How Long Does it Take to Get a PhD?

How long does it take to get a PhD? On average, PhD programs are 4 or 5 years long. The time it takes to get a PhD is slightly longer in the US, between 4-6 years, because these programs tend to be more structured. If you want to know how to get a PhD in Canada or Europe, you can expect it to take 3-5 years. However, there are PhD programs that take longer, such as part-time programs, or are extremely short, like online accelerated PhD programs. Ultimately, how long it takes to get a PhD is up to you. In this article, we’ll look at the average PhD program lengths, the typical PhD timeline, and tips on how to get your PhD finished faster.

How long does it take to get a phd.

On average, it takes 4-5 years to complete a Doctor of Philosophy (PhD) program. In the US, most PhD programs are between 4-6 years, while in Canada they are typically shorter, around 3-4 years.

Some students take longer than 6 years to complete their PhD, but in general the longest time it takes to get a PhD is capped at 8 years. If you’re enrolling in a part-time PhD program, for instance, your timeline will probably be extended to 6-8 years.

The shortest PhD programs out there are accelerated or sometimes online PhD programs. Some of these are only 1-2 years long, but there are comparatively fewer programs available, and they are only suitable for certain fields and careers which require less intensive research which defines most PhD programs.

One of the main reasons why it takes many years to get a PhD is because these programs are comprehensive and the requirements to graduate are extensive. Most have a set number of credit hours you need to complete, examinations to write, plus you’ll need to write your PhD thesis or dissertation, unless you pursue a PhD without dissertation .

There are certainly ways to shorten the PhD application timeline and time to graduate, which includes enrolling in a shorter program if possible, increasing your course load or the number of research hours you can dedicate per week, but generally a PhD will still take some time.

Even if you want to do a PhD without a master’s degree first, such as by applying to a direct entry PhD program, the program is still usually 4-5 years long.

We’ll take a look at the typical PhD timeline and how long it takes to get a PhD normally. After, we’ll cover some tips on how to get your PhD done faster or how you can avoid dragging things out.

In North America, the typical PhD program is divided into two stages. The first stage is where you complete all the required coursework, comprehensive exams and other academic requirements, depending on the program. The second stage is when you submit a proposal for original, independent research, get it approved and start working on your thesis or dissertation. Your PhD culminates with your thesis defense. Once your thesis has been approved, you’ll be eligible to graduate.

This timeline is somewhat flexible, as you might complete the first stage in 1 or 2 years but take longer to complete your dissertation. For the purpose of this general PhD schedule, we’ll assume your PhD program is a typical length of 4-6 years.

Application Stage

We’ve included the application stage of getting your PhD here first because the grad school application timeline can take several months to put together your application package and hear back about acceptance to a program. Secondly, because the application stage involves some critical steps you’ll need to complete in order to get your PhD.

1. Research proposal

To apply to a PhD program, you’ll most likely be required to submit a research proposal and be prepared to answer any research proposal questions your advisor will have. This is your “proposal” of what research question you will explore during your studies at a program, or an outline of what research topic you want to pursue. If you’re not sure how to write a research proposal, check out these Oxford PhD proposal samples or a Cambridge PhD proposal sample.

2. Application materials

The admission requirements for a PhD can vary from program to program, but here are the general components of a PhD application:

  • Required prerequisite coursework
  • Official transcripts (and minimum GPA)
  • Graduate school statement of purpose
  • CV for graduate school or research resume
  • PhD motivation letter

Some programs may also ask you to submit additional essays, such as a letter of intent, research interest statement or grad school career goals statement .

Many PhD programs also invite you to a grad school interview to get to know you better. Be ready for common graduate school interview questions such as “ tell me about yourself ” and “ why do you want to do a PhD ?”

PhD Years 1-3: Coursework Stage

1. orientation.

Your PhD program will usually begin with your orientation, where you’ll learn about the program’s individual structure, requirements and expectations. You’ll also either choose or be assigned an academic advisor and schedule an initial meeting with them. Your advisor will be a member of the university faculty who will act as your support while you complete your research and write your thesis.

2. Coursework

The first year or two of your PhD will involve completing required advanced coursework in your field. You’ll attend lectures and seminars and you may participate in research projects with department faculty or fellow graduate students or even lab work, depending on your field.

3. Electives

Along with required coursework, you’ll have the chance to take elective courses that interest you or relate to your field. It’s important to choose electives that will enrich your program. Choose ones that really interest you, that might help inform your PhD research or that will help you fulfill your credit requirements.

4. Extracurriculars

PhD programs sometimes have extracurricular activities or additional requirements outside the classroom. This can include internships or a practicum you need to complete for credit, or you might be interested in attending academic conferences or relevant events to socialize and network you’re your colleagues in the field.

5. Comprehensive exams

The coursework stage of your PhD program will end with comprehensive exams , sometimes called qualifying or preliminary exams. These are your “final exams” to make sure that you completed the necessary PhD coursework and that you’re ready and qualified to take on your own independent research in the next phase.

1. Thesis proposal

You may recall that you submitted a research proposal as part of your PhD application, and this step of the process is similar. Your thesis proposal is just like your research proposal, but it’s a more refined and developed version. Throughout your coursework, your research question might have changed or you might have changed course a little bit. If you’re still thinking about your PhD topic , take the time to solidify it before you reach the thesis proposal stage.

Your research proposal might have been a first draft, while your thesis proposal is your official announcement of: this is what I propose to research in this PhD program.

Depending on your field and the program, you thesis research might involve a great deal of lab work, or data collection or fieldwork. Whatever the case, your thesis proposal is a complete outline of what you intend to do for this independent research project and the steps you’ll take.

2. Thesis approval

Once your proposal is written, you’ll submit it for approval. Your academic advisor, PhD supervisor or the PhD committee overseeing your program will review it and either approve it or make suggestions for changes. Once it’s been polished and finalized, you’ll be given the go ahead to start conducting your research.

3. PhD research

Your research alone will probably take you several semesters to complete. On top of the fieldwork, lab work or data collection and analysis you’ll be completing, you’ll be using this time to write and review. Writing your thesis or dissertation takes a fair number of hours to outline, draft, edit and complete. It also means hitting the books to complete a literature review of your research topic so you have a complete background understanding of your chosen topic and how it will inform your research.

Your research and the preparation of your thesis is really the biggest part of this second stage, and is probably the longest part of your PhD altogether.

4. Extra requirements

When you’re not deep in your research, you’ll be completing other requirements of your PhD program or additional duties that enrich your education. Some programs require you to dedicate some hours to teaching, whether it be leading seminars for undergraduate students or acting as a teaching assistant for university faculty.

You’ll also be strongly encouraged to publish as a graduate student , so you may be involved in the research projects of faculty members or other grad students when you’re not working on your dissertation.

5. Thesis submission and preparation for thesis defense

When you’re finished writing your thesis and you’re ready to submit it, it’s critical to know how to prepare for thesis defense . Because not only do you have to complete this original, new body of research work, you have to get the approval of your PhD committee to put it out into the world.

Your thesis defense is essentially the final presentation of your PhD.

6. Thesis defense

Your thesis defense is an oral presentation of your research project, but it also involves submitting your written document to be reviewed. Essentially, you’ll present the entirety of your thesis to the PhD supervising committee, including your findings and conclusions. From there, the committee will ask thesis defense questions . Your answers will defend your methodology and results to the committee, basically proving the value and validity of your work. While this is an evaluation of sorts, it is also your opportunity to share your original ideas and invite further research into your topic.

After your defense, the PhD committee will either approve your thesis or send it back to you with edits or changes to be made before it can be formally approved.

Graduation and Postdoc

Once your thesis has been approved, congratulations! You’ll be eligible for graduation and be awarded your degree. Now that you’ve finished this marathon, you can choose to pursue further studies or start looking for a job after grad school .

With a PhD, you have many different options for positions in your field. You might want to know how to find a job in academia or how to get a tenure track position at a university if you’re interested in teaching others. PhD graduates who decide to transition from academia to industry or who would rather work outside the realm of academia can find industry jobs after PhD that suit their skills and experiences.

Either way, you’ll need to prepare for how to find a postdoc position, explore what the career options are for you, decide what your career goals are and start sending out applications. Remember to prep your postdoc resume and get read for postdoc interview questions , since the job hunt will begin soon after you finish your PhD!

Is it possible to get your PhD done faster? What are some ways you can speed up the process and avoid taking 8 years to complete your graduate studies? Luckily, there are many key ways you can make your journey through grad school easier and speed things up a little, from the type of PhD program you choose to the habits and skills you cultivate during your program.

#1 Enroll in an accelerated program

The first way to guarantee it will take less time to get your PhD is to, of course, enroll in a shorter PhD program. Direct entry PhD programs allow you to enroll once you’ve completed your bachelor’s degree in exceptional circumstances. Note that these are not the easiest PhD programs to get into , as your academic record needs to be excellent, and you’ll likely need prior research experience and you may even need to have publications already. However, a direct entry PhD program is around 4-5 years, but it allows you to skip the 1-2 years it would take to earn a master’s degree.

You can also choose to enroll in an online or accelerated PhD program that is designed to be much shorter than the traditional PhD. Once again, though, these programs are not available to students in every field, so you may need to research whether there are any options for you.

#2 Choose the right mentor

One of the first things you can do to ensure your PhD is smooth sailing is to choose the right mentor or academic advisor. Many programs allow you to choose your advisor, while some assign one to you. Whatever the case, it’s important to establish a strong working relationship and clear expectations early on.

One of the first things you’ll do as a PhD student is meet with your advisor. Take the time to discuss with them what your expectations for the program are, ask questions and ask them what their expectations are of you. Your advisor is there to help you and advise you, and they have resources and connections you can use to your advantage. But they are also working with a busy schedule and might be advising more than one PhD student, too. A mutually respectful relationship with open communication will ensure fewer interpersonal hurdles down the road.

#3 Earn credit hours faster

One way you can shave some time off your PhD is by earning your credit hours faster and getting to the research and thesis-writing stage faster. This might mean you take on a full-time course load or ask your advisor for ways to earn extra credit, such as participating in research projects. Some PhD programs will give you course credit for previous graduate level coursework you might have completed during your master’s degree, or for certifications and professional education you completed outside of school.

#4 Keep your thesis focused

When you get started on your research, it’s easy to feel overwhelmed with the amount of work you need to complete, with the writing of your thesis on top of it all. One way to keep your research hyper-focused and on point is to keep your thesis topic narrow. If your subject is too broad, you’ll be spending way too much time in your research. Give yourself clear objectives and scope, and don’t deviate from your PhD proposal if you don’t have to.

There may be a million questions you want to explore within your PhD topic, but there will be other opportunities to explore them. Keep your focus narrow so you don’t spend years and years asking and answering research questions!

One of the best things you can do to get your PhD done faster and adjust to the experience of graduate school is to change your thinking. Adopt a growth mindset so that you’re open to new learning, willing to listen to constructive feedback on your proposal or thesis and willing to grow your skills. A PhD is an advanced program, and you’ll already be very skilled, but it is also an opportunity to learn and grow. There will be challenges for you, so be ready to meet and overcome them instead of letting them draw you back or slow you down.

#5 Develop your professional skills fast

A PhD is an opportunity to grow your professional skillset as much as it is an opportunity for you to contribute meaningfully to your field. If you haven’t already been working on skills such as communication, presenting or lecturing and writing, now is the time to start.

Strong writing skills will help you get your thesis finished and edited faster, as you’ll be more familiar with the process and understand what makes a strong document. It’s also a useful skill to learn how to write effective funding proposals or grant proposals. You may need to do so to secure funding for your research, but it’s a highly valuable skill in the workforce, too.

Good presentation skills will help you during your thesis defense or if you’re asked to present during a conference. They will also help you build confidence in your voice and ideas and make you a better communicator when you’re networking or job searching.

#6 Keep to your schedule

This is maybe the most important skill if you want to finish your PhD faster: make a detailed schedule and hold yourself accountable to it. If you like, you can plan out your entire PhD week by week from Day 1. Write down what your course schedule is, when you’ll do research and how many hours, when you’ll write and how many hours, what extracurriculars or personal activities will take up your time and so on.

A detailed schedule gives you an overview of your PhD and a timeline of when you’ll finish. It will keep you organized and accountable, so you can avoid procrastinating or avoidable speed bumps that might slow you down. It also helps you compartmentalize the many items on your to-do list so you don’t stress out about how much you need to accomplish.

When creating your schedule, especially during the research stage when there is no formal class schedule for you to adhere to, focus on deliverables. Set a date when you will submit a section of your thesis to your advisor, or when you will complete your literature review. Setting goals and clear outcomes will keep you on track and focused.

#7 Take initiative and be independent

The last tip to help you get your PhD done faster is to take initiative. Remember that a PhD is a largely independent endeavor. You’ll have the support of a committee or advisor, but you can’t rely on them to do the work for you or put everything on hold if they aren’t available when you need them. Be flexible and adaptable so you can keep working and moving forward, even if your schedule gets interrupted or needs to change to suit your situation.

It's also important to take the initiative in your learning. Take advantage of opportunities for growth, networking, and gaining experience where you can. Get the most out of your PhD program and use your experiences to fuel your end goal of completing your thesis.

On average, it takes 4-5 years to get a PhD. There are a few factors that can influence the time it takes to complete your PhD, from program length and structure to what country you are earning your PhD in, to your own personal work ethic and schedule.

PhD programs in the US are on average 4-6 years. In Canada and the UK, they are usually 3-5 years long. Part-time PhD programs may take up to 7-8 years to complete. Direct-entry PhD programs and dual master’s and PhD programs are typically 5 years long. If you’re enrolling in an online, hybrid or accelerated PhD program, the timeline is usually 2-3 years, but there are some extremely short 1-year PhD programs offered online for specific disciplines.

Yes, you can finish your PhD before the “normal” timeline. For example, if you complete your coursework early, if you finish writing your thesis faster than average and get it approved, or if you otherwise complete all your PhD program requirements before the anticipated finish date. 

Yes, there are online PhDs available for certain fields and disciplines. These typically range from 2-3 years, although there are some traditional 4-year PhD programs offered online. There are also some “accelerated” online PhDs which last 12-18 months.

A PhD program is not necessarily shorter if you first complete a master’s degree, but having gone through a master’s program can better prepare you to finish your PhD faster. Some PhD programs accept credit hours from your master’s degree towards the coursework requirements for a PhD, and if you’ve previously written a master’s thesis or completed some research during your graduate studies, this will be an advantage. Since you’ll already be familiar with the process of writing a thesis and conducting your own research, you can avoid some stumbling blocks in your PhD program that might otherwise slow down your progress.

Yes, it is possible to get a PhD without first completing a master’s degree. There are direct entry PhD programs that allow students with a bachelor’s degree to enroll, so long as they meet the admission requirements and have exceptional academic records. Some online PhDs also waive the master’s degree requirement.

Yes, it is possible to complete a traditional PhD program in a shorter amount of time than anticipate. This usually means dedicating yourself to full-time study or taking on a larger course load and increased research hours. It takes significant work, but it can be done with the right schedule and commitment.

The fastest PhD programs are the short, 1-year accelerated programs. These programs have fewer credit hours to complete, and some have no dissertation requirement, only qualifying exams to finish. However, there are not many programs out there, and they are not available for every field of interest.

How to finish your PhD is less time

Look for accelerated classes.

Accelerated courses are an easy way to reduce the amount of time it takes to finish a PhD. Therefore, look into if your program offers any shorter courses. 

Work on your dissertation throughout the program

Working on your dissertation little by little throughout the program will allow you to speed up your doctoral timeline. In addition, it may reduce the likelihood that you’ll drop out before finishing your final project.

Maintain regular communication with your advisor

Establish regular communication with your advisor or supervisor. Regular meetings can help you receive guidance, address any issues, and ensure you are heading in the right direction.

Seek feedback early and often

Share your work and progress with your advisor, peers, or other trusted individuals often. Then, you should incorporate suggestions and revisions as you go along. This will help you refine your work and avoid major revisions later.  

Maintain a healthy school-life balance

While it is important to be dedicated to your PhD, it’s just as important to maintain a healthy work-life balance. Therefore, be sure to prioritize yourself! While finishing your PhD in less time is a great feat, it is important that you are not sacrificing your well-being while doing so.

How Long Does It Take to Get a PhD?

If you aspire to rise to the top of your field, then you may have your sights set on a PhD.

PhD students in a group study

Earning a doctoral degree can be a years-long process, but choosing an accelerated doctoral online program may help you complete your program more quickly.

Editorial Listing ShortCode:

Whether you’re wanting to earn one of the highest paying doctoral degrees or you have a specific one in mind, this guide can help walk you through how long it takes to complete your PhD program.

a watch showing years

For a traditional, campus-based PhD program, the average time to finish a PhD is 8 years. Fulfilling the program’s requirements will often demand a serious investment of your time.

Even still, some people are able to finish their programs in just 3 to 6 years. Multiple factors may influence the overall length of your program.

Required Credit Hours

Many PhD programs require you to earn 120 credit hours before entering the exam and dissertation phases.

Fortunately, there are PhD programs without such high credit-hour demands. For example, at some universities, you may earn a PhD with only 60 credit hours.

Full-Time vs. Part-Time Schedule

Enrolling in a doctoral program part-time may allow you to keep up with your regular job. You’ll have to decide whether you prefer the flexibility of part-time schooling or the faster schedule of full-time studies.

Final Project Requirements

Many PhD programs end with the completion of a dissertation. This assignment may take years to complete, so PhD students often end up in the all-but-dissertation (ABD) phase for quite some time.

University Scheduling

Some schools promote their ability to help you through the PhD process faster than normal. Accelerated class schedules with eight-week online courses may speed your studies along. Focused attention from dissertation advisors may help as well.

PhD Program Components

students in class

Before you enroll in a PhD program, it’s important to know some of the basic requirements:

Prerequisites

Most schools require you to already hold a master’s degree, but some offer bachelor’s-to-PhD programs.

Length to Completion

On average, it takes eight years to earn a PhD. Even still, completing doctoral coursework and a dissertation in three to four years is not unheard of.

Topic of Interest

PhD stands for Doctor of Philosophy, but that doesn’t mean you’ll be getting a philosophy degree. Your field of study will depend on your interests and the programs that your university offers. You may tailor your doctoral focus though your choice of a dissertation topic.

Steps to Completion

You’ll take advanced classes before sitting for comprehensive exams. After passing your exams, you’ll likely begin working on a dissertation. You must defend your dissertation before finishing your program.

Doctoral studies begin with a series of classes through which you may increase your knowledge of your field of study and learn about conducting research. These are advanced classes, so they should be more in-depth than the ones you took during your undergraduate and master’s programs.

The number of courses that you need to take can vary significantly. It’s not uncommon for PhD programs to require 120 credit hours of coursework. That amounts to about 40 classes.

At other schools, the requirements are lower. Your university’s program may involve just 60 credit hours or, possibly, even fewer. A less intense course load may significantly slash your time to completion.

Your university may require you to maintain a GPA above a minimum threshold. An unsatisfactory GPA may keep you from moving on to the next step of the PhD process.

Comprehensive Examinations

Universities often require students to demonstrate their readiness for a doctoral project before advancing to the next stage of their studies. Readiness is proven through comprehensive exams , which may also be known as:

  • Preliminary examinations
  • Major field examinations
  • General examinations

Often, comprehensive exams take the form of written or oral tests. In other situations, faculty may assess students’ readiness on the basis of a portfolio evaluation or a written paper.

Dissertation and Defense

PhD dissertation paper

A dissertation, also known as a graduate thesis, is a body of work that presents original research in your field. This manuscript focuses on a unique idea and includes evidence to support your thesis. During your doctoral studies, there are classes designed to help prepare you for your dissertation work.

The dissertation process may take several years. Once your manuscript is complete, you must defend it to the doctoral program faculty. After your defense, you may need to do further work on your manuscript, or the committee may decide that your dissertation is complete.

Not all programs require a dissertation. Instead, there may be an alternative doctoral project. Although both dissertations and capstone projects are rigorous, projects can sometimes be completed within a shorter time frame.

Average Time to Complete PhD by Field of Study

Students in some disciplines usually take a lot more time to finish their doctoral work than students in other fields.

If you’re studying in the following scientific fields, you may be more likely to earn your on-campus degree in seven years or less:

  • Physics — average of five years
  • Psychology — average of five to seven years

On the other hand, if your field of study relates more to the humanities, your on-campus degree program may take longer:

  • History — average of eight years
  • English — average of eight years
  • Education — average of 13 years

These are the traditional figures. There are ways to finish faster.

Some schools require doctoral students to take around 40 classes, which, in a traditional on-campus setting, may take years. After completing the coursework, you must write your dissertation and defend it. The dissertation process alone might take multiple years.

Doctoral programs online may help shorten the PhD process to three or four years. Fewer credit hours may be required, and the classes may be delivered in an accelerated format.

Schools with an emphasis on quick doctoral programs may also offer dissertation advisors to efficiently guide students through that phase. Alternatively, some universities allow students to complete capstone projects that don’t take as long as dissertations.

Getting a PhD Online vs. Campus

Online education has changed students’ options for earning a PhD. These days, aspiring students may choose whether to attend classes on a college campus or online.

Traditional programs may require you to relocate to the university’s campus and attend school full-time. On average, it takes just over eight years to complete those programs. The benefits of choosing an online school instead may include:

Faster Progress

Accelerated eight-week courses may allow you to finish your course load sooner. You may complete your entire program in just three or four years.

Multiple Start Dates

Online programs often let you join throughout the year, so you don’t have to put your studies on hold until the fall semester.

Flexibility

Not being required to move to campus or come to class at set times may allow you to work your studies around your schedule.

Equal Status

Online programs are just as rigorous as on-campus ones. As long as your university is accredited, your degree will be just as valuable as one from a traditional university setting.

Cost-Savings

Finishing your doctoral studies faster may mean that you pay less tuition.

How to Finish Your PhD in Less Time

Although you can’t earn a doctoral degree overnight, you shouldn’t have to spend the majority of your working years striving toward PhD-completion. The following tips for accelerating the PhD process may help you finish your studies more quickly than the average doctoral student.

1. Use What You Already Know

Every school requires a minimum number of credit hours that you must earn in the pursuit of your degree. To help you meet this threshold, some schools will allow you to transfer in credits from other doctoral programs. Universities may also give you credit for your professional experience. Reducing your class load may save you both time and money.

2. Look for Short Classes

Accelerated course schedules are one of the best ways to speed through the degree process. Every eight weeks, you’ll begin a new set of classes. Over the course of a year, there may be five different sessions during which you can take classes.

3. Work on Your Dissertation Throughout the Program

Traditionally, dissertation work begins once the classroom portion of your studies is over. Quick doctoral programs may allow you to begin the dissertation process while you’re still taking other classes. This approach, known as an embedded dissertation, may reduce the likelihood that you’ll drop out before finishing your final project. It might also speed up your doctoral timeline.

4. Ask for Help

A lack of support can lead some doctoral students to drop out. On the other hand, having a good support system can help you push through and finish your program more quickly. Build a team of family, friends, and academic mentors who can encourage you, guide you, and lend practical help when you’re feeling overwhelmed by school.

Why Get a PhD?

You may need to earn a doctoral degree to achieve your career goals . For example, if you want to become a clinical psychologist, this level of study is essential. Many scientific and research positions require doctoral studies. University faculty typically need to hold terminal degrees as well.

Even if a doctorate is not a requirement for your desired line of work, it may help you achieve greater success. You might be granted higher levels of responsibility, and you may earn more money. In some fields, those who hold PhDs make around 20% more than those with master’s degrees, according to the Bureau of Labor Statistics .

Do You Have to Have a Master’s Degree to Get a PhD?

Many schools consider a master’s degree an essential prerequisite for PhD admission. If you don’t already have a master’s degree, a bachelor’s-to-doctorate program may allow you to earn a master’s and a PhD for less time and money than it would take to pursue them separately.

How Long Does It Take to Get a PhD After a Master’s?

You may be able to complete your doctoral program in three to four years if you opt for an accelerated online program. On average, traditional on-campus PhD programs take around eight years to complete.

How Hard Is It to Finish a PhD?

Doctoral studies are challenging. That shouldn’t come as a surprise; if doctorates were easy to acquire, nearly every college graduate would end up with a PhD behind his or her name.

Approximately 50% of students who begin a PhD program don’t end up finishing. Many quit within two years of starting. Another large portion gives up upon reaching the dissertation phase.

Although all PhD programs are challenging, the flexible nature of online programs may help you find success. Choosing a doctoral track that doesn’t require a dissertation may help as well.

What Is the Easiest PhD to Get?

Easiest PhD to Get

All PhD programs are demanding, but you might have an easier time if you select a program that aligns with your interests and your career goals. The flexibility of online study may help your doctoral program seem less burdensome. In addition, capstone projects are sometimes easier than writing dissertations.

If earning a doctoral degree in a short time frame is important to you, then consider the many potential benefits that online programs have to offer. Within just a few years, you may be able to place the letters “PhD” at the end of your name.

How Do You Get a PhD? A Guide to the PhD Timeline

Man sits at a library table researching several books.

Everyone who considers a doctoral degree knows a PhD is a big commitment. 

Not only will it require all your mental energy, focus, and persistence, but it will also require a significant investment of your time. Your particular area of research, your institution’s policies and procedures, and the standard expectations within your field affect how long it takes to earn a PhD. The average PhD length is five or six years, while some students may take eight or nine years.

Regardless of how long a PhD program takes,  there are some common stages of a PhD that all doctoral students share. These significant and essential milestones shape the timeline for earning your doctorate . Read on as we take you through each step and explore the typical steps to a doctorate degree.

Are you just starting to apply to graduate school? Check out our Guide to  Graduate Admissions to get all your questions answered! 

How Long Do PhD Programs Take?

The number of credit hours that you need to complete your doctoral coursework might depend on several factors: do you already have a master’s degree? Will you earn one en route to the doctorate? Or do you even need one? 

Different disciplines and research interests have their own PhD process, but even within your field of study, institutions may have diverse pathways for obtaining that terminal degree. For most, coursework will take anywhere from two to three years to complete.

During this time, students can serve as graduate research or teaching assistants or could even lead their own courses as instructors. In many degree programs, students develop their potential dissertation topics through their coursework and define their research plans in the next few years.

Steps to Getting a PhD: PhD Qualifying Exam and Comprehensive Exam

Many programs set up academic checkpoints to help keep students on track during their PhD journeys. The timing varies by program, but one of the most common – and possibly most stressful – forms of benchmarking is the PhD comprehensive exam or qualifying exam. Often administered around the end of the student’s coursework, these exams are your chance to demonstrate what you learned in your classes.

A faculty committee from your department oversees testing. Usually comprised of at least three members, your professors ask questions or assign writing prompts based on your experience in the program thus far. The format is generally a combination of written and oral exams designed to test your expertise in your discipline’s methodologies and significant content areas.

To better prepare yourself, research the number and kind of qualifying benchmarks the program will require in the university catalog before you begin your program. This will allow you and your advisor to effectively plan out the first few years of your degree and give you an idea of how you’ll be evaluated throughout your program.

Doctoral Dissertation Prospectus and Defense

You may be required to complete and defend a dissertation prospectus before officially becoming a PhD candidate. A prospectus is a document outlining your dissertation plan, which includes an explanation of your research topic, a potential outline of your dissertation, the methodologies you intend to employ, the significance of your research question, and a bibliography including sources that form the foundation of your research.

Your prospectus allows your dissertation advisor to understand the scope of your project. It should be thorough enough that they can provide useful feedback to help shape your research plan. After some revisions, an approved prospectus is the green light to move into the next stage of your PhD.

Advancement to Doctoral Candidacy

If you have heard the term ABD – “All But Dissertation” – then that means you are in the home stretch of your doctoral program!

Well, sort of…only your dissertation remains!

Doctoral Dissertation Research and Writing

While you’ve made it through the coursework and qualifying exams, the dissertation is the culminating component of the doctoral degree. At this point, your approved research plan is ready to be set into motion. Depending on your discipline, this could be the stage where you travel extensively to conduct fieldwork, explore archives, or visit labs to collaborate on projects that relate to your dissertation work. For many students, the research phase can take a couple of years, but some may be able to complete it in one.

Writing your dissertation can be one of the most challenging parts of the whole PhD process. Not only are you condensing years of research into a single cohesive document, but you are also formulating graphs, charts, and other textual references to help clarify your argument. Often, formatting can be a major challenge for many students. 

In this stage, it’s most helpful to seek out resources to help you with the writing process. Many universities have dissertation writing workshops where you can learn best practices, as well as support groups where students meet regularly and help keep each other accountable. Most universities also offer competitive dissertation completion grants, supporting students with additional funding so they focus more of their time and effort on completing this undertaking.

Dissertation Defense

Everyone gets nervous about this major rite of passage. It can be difficult to take criticism over something you have poured your heart and soul into for years. Remember, though, that a good advisor will not let you defend if you’re not ready, and you literally wrote the book on your topic!

The dissertation defense is not intended to tear your work apart but rather is your opportunity to prove your expertise to your dissertation committee. Many defenses are open to observers, so you should attend a few in advance of your own, especially within your department, to get a sense of what it’s like. 

First, you’ll present the main points of your thesis. Then the committee will ask questions so they can clearly understand your arguments. Finally, they’ll send you out of the room while they deliberate and decide if you pass or not. If all goes well, you’ll be addressed as “Doctor” the next time you walk into the room!

Get Started on Your PhD Journey Today

No matter what your particular timeline looks like as you work toward your doctorate, know that the faculty and other students within your program are frequently a huge source of support — which means you won't do this alone! Additionally, every school has resources to assist PhD students, from libraries to writing centers to dedicated student support services.

Earning a Ph.D. from a U.S. grad school typically requires nearly six years, federal statistics show.

how many years to get a phd degree

(CAIAIMAGE/TOM MERTON/GETTY IMAGES)

A Ph.D. is most appropriate for someone who is a “lifelong learner.” 

Students who have excelled within a specific academic discipline and who have a strong interest in that field may choose to pursue a Ph.D. degree. However, Ph.D. degree-holders urge prospective students to think carefully about whether they truly want or need a doctoral degree, since Ph.D. programs last for multiple years.

According to the Survey of Earned Doctorates, a census of recent research doctorate recipients who earned their degree from U.S. institutions, the median amount of time it took individuals who received their doctorates in 2017 to complete their program was 5.8 years. However, there are many types of programs that typically take longer than six years to complete, such as humanities and arts doctorates, where the median time for individuals to earn their degree was 7.1 years, according to the survey.

Some Ph.D. candidates begin doctoral programs after they have already obtained master’s degrees, which means the time spent in grad school is a combination of the time spent pursuing a master’s and the years invested in a doctorate. In order to receive a Ph.D. degree, a student must produce and successfully defend an original academic dissertation, which must be approved by a dissertation committtee. Writing and defending a dissertation is so difficult that many Ph.D. students drop out of their Ph.D. programs having done most of the work necessary for degree without completing the dissertation component. These Ph.D. program dropouts often use the phrase “ all but dissertation ” or the abbreviation “ABD” on their resumes.

According to a comprehensive study of  Ph.D. completion rates  published by The Council of Graduate Schools in 2008, only 56.6% of people who begin Ph.D. programs earn Ph.D. degrees.

Ian Curtis, a founding partner with H&C Education, an educational and admissions consulting firm, who is pursuing a Ph.D. degree in French at Yale University , says there are several steps involved in the process of obtaining a Ph.D. Students typically need to fulfill course requirements and pass comprehensive exams, Curtis warns. “Once these obligations have been completed, how long it takes you to write your dissertation depends on who you are, how you work, what field you’re in and what other responsibilities you have in life,” he wrote in an email. Though some Ph.D. students can write a dissertation in a single year, that is rare, and the dissertation writing process may last for several years, Curtis says.

[ READ: What Is a Doctorate or a Doctoral Degree?  ]

Curtis adds that the level of support a Ph.D. student receives from an academic advisor or faculty mentor can be a key factor in determining the length of time it takes to complete a Ph.D. program. “Before you decide to enroll at a specific program, you’ll want to meet your future advisor,” Curtis advises. “Also, reach out to his or her current and former students to get a sense of what he or she is like to work with.”

Curtis also notes that if there is a gap between the amount of time it takes to complete a Ph.D. and the amount of time a student’s funding lasts, this can slow down the Ph.D. completion process. “Keep in mind that if you run out of funding at some point during your doctorate, you will need to find paid work, and this will leave you even less time to focus on writing your dissertation,” he says. “If one of the programs you’re looking at has a record of significantly longer – or shorter – times to competition, this is good information to take into consideration.”

Pierre Huguet, the CEO and co-founder of H&C Education, says prospective Ph.D. students should be aware that a Ph.D. is designed to prepare a person for a career as a scholar. “Most of the jobs available to Ph.D. students upon graduation are academic in nature and directly related to their fields of study: professor, researcher, etc.,” Huguet wrote in an email. “The truth is that more specialization can mean fewer job opportunities. Before starting a Ph.D., students should be sure that they want to pursue a career in academia, or in research. If not, they should make time during the Ph.D. to show recruiters that they’ve traveled beyond their labs and libraries to gain some professional hands-on experience.”

Jack Appleman, a business writing instructor, published author and Ph.D. candidate focusing on organizational communication with the  University at Albany—SUNY , says Ph.D. programs require a level of commitment and focus that goes beyond what is necessary for a typical corporate job. A program with flexible course requirements that allow a student to customize his or her curriculum based on academic interests and personal obligations is ideal, he says.

[ READ: Ph.D. Programs Get a Lot More Practical.  ]

Joan Kee, a professor at the University of Michigan  with the university’s history of art department, says that the length of time required for a Ph.D. varies widely depending on what subject the Ph.D. focuses on. “Ph.D. program length is very discipline and even field-specific; for example, you can and are expected to finish a Ph.D, in economics in under five years, but that would be impossible in art history (or most of the humanities),” she wrote in an email.

Jean Marie Carey, who earned her Ph.D. degree in art history and German from the  University of Otago  in New Zealand, encourages prospective Ph.D. students to check whether their potential Ph.D. program has published a timeline of how long it takes a Ph.D. student to complete their program. She says it is also prudent to speak with Ph.D. graduates of the school and ask about their experience.

Bennett urges prospective Ph.D. students to visit the campuses of their target graduate programs since a Ph.D. program takes so much time that it is important to find a school that feels comfortable. She adds that aspiring Ph.D. students who prefer a collaborative learning environment should be wary of graduate programs that have a cut-throat and competitive atmosphere, since such students may not thrive in that type of setting.

[ READ: 4 Fields Where Doctorates Lead to Jobs.  ]

Alumni of Ph.D. programs note that the process of obtaining a Ph.D. is arduous, regardless of the type of Ph.D. program. “A Ph.D. is a long commitment of your time, energy and financial resources, so it’ll be easier on you if you are passionate about research,” says Grace Lee, who has a Ph.D. in neuroscience and is the founder and CEO of Mastery Insights, an education and career coaching company, and the host of the Career Revisionist podcast.

“A Ph.D. isn’t about rehashing years of knowledge that is already out there, but rather it is about your ability to generate new knowledge. Your intellectual masterpiece (which is your dissertation) takes a lot of time, intellectual creativity and innovation to put together, so you have to be truly passionate about that,” Lee says.

Erin Skelly, a graduate admissions counselor at the IvyWise admissions consulting firm, says when a Ph.D. students struggles to complete his or her Ph.D. degree, it may have more to do with the student’s academic interests or personal circumstances than his or her program.

“The time to complete a Ph.D. can depend on a number of variables, but the specific discipline or school would only account for a year or two’s difference,” she wrote in an email. “When a student takes significantly longer to complete a Ph.D. (degree), it’s usually related to the student’s coursework and research – they need to take additional coursework to complete their comprehensive exams; they change the focus of their program or dissertation, requiring extra coursework or research; or their research doesn’t yield the results they hoped for, and they need to generate a new theory and conduct more research.”

Skelly warns that the average completion time of a Ph.D. program may be misleading in some cases, if the average is skewed based on one or two outliers. She suggests that instead of focusing on the duration of a particular Ph.D. program, prospective students should investigate the program’s attritition and graduation rates.

“It is worthwhile to look at the program requirements and the school’s proposed timeline for completion, and meet current students to get their input on how realistic these expectations for completion are,” Skelly says. “That can give you an honest idea of how long it will really take to complete the program.”

  • PhD in USA – A Guide for 2024/25
  • Finding a PhD

A PhD in USA takes approximately 5 – 6 years of full-time study and can cost between $12,000 – $45,000 per academic year. PhD programs in USA differ from that in the UK and Europe in that students must first take taught classes, coursework and exams before starting their research project.

Why Do a PhD in USA?

The United States has long had some of the most distinguished universities and advanced PhD programmes in the world. Combined with curriculum flexibility, rigorous teaching methods, vast funding opportunities, breathtaking campuses and significant career prospects, it’s no wonder that it is one of the most sought-after study destinations for research students.

In addition to comprehensive training standards, here are a few other reasons why a student may choose to undertake their PhD in the United States:

  • Longer learning timeframes – A PhD in the US lasts longer than a PhD in the UK or Europe. This allows students to more confidently transition from undergraduate to postgraduate studies; more commonly referred to as ‘graduate studies’ in the US. This gives you the opportunity to learn more about your subject, research methods and academic writing in general before starting your research project.
  • World-class universities – It’s no secret that some of the most well-known higher education institutions that continue to dominate global rankings are based in the United States. Although many factors go into determining whether a position is right for you, a PhD at a high-ranking American university will undeniably have many benefits, from excellent learning standards to access to innovative equipment and deep expertise.
  • International network – The US has long been a popular choice among PhD students around the world. As such, the US hosts a diverse and multicultural learning environment in which many research students will quickly feel at home.
  • Opportunities – With over 4,000 universities in the US, we can safely say you will have plenty of opportunities to find the ideal combination of project, supervisor and university that works for you.

Universities in USA

Universities in the United States can be divided into two types: public universities and private universities.

Public universities are financed by the state in which they are based. Because of this, public universities charge less for students from within the state and more for students from outside the state, including international students.

Private universities are not financed by their state, but by private donors, research funds and tuition fees. For this reason, private universities generally charge higher tuition fees than public universities and require all students to pay the same amount, regardless of whether they come from out-of-state or abroad.

According to the Times Higher Education World University Rankings 2024 , eight of the top ten universities in the world are located in the United States. These are:

1 UK University of Oxford
2 USA Stanford University
3 USA Massachusetts Institute of Technology
4 USA Harvard University
5 UK University of Cambridge
6 USA Princeton University
7 USA California Institute of Technology
8 UK Imperial College London
9 USA University of California, Berkeley
10 USA Yale University

Method of Study

The main difference between a PhD in the US and a PhD in Europe lies in the program structure. Whereas a European PhD essentially consists of a single phase lasting three to four years , an American PhD consists of three different phases, each with its own time frame.

  • Phase One – The first phase lasts approximately two years and focuses on building a basic foundation for the doctoral student. This phase consists largely of taught components such as lectures, tutorials and laboratory sessions, in which the student learns more about theoretical concepts and research methods within their discipline.
  • Phase Two – The second phase can be considered an assessment phase, which runs both periodically alongside and at the end of the first phase. Here, students complete coursework and take exams on the basis of the material they have covered of which they must pass in order to proceed to the third phase.
  • Phase Three – The third phase lasts approximately three years and resembles the European PhD structure. During this period, the student undertakes an independent research project, including forming a research design, conducting experiments, writing a thesis (more commonly referred to in the USA as a dissertation) and sitting a viva exam.

Teaching Requirements

Besides structure, a key difference between a PhD program in the US and in Europe is the focus on teaching requirements. In the US, doctoral students are expected to lecture, lead tutorials, host laboratory sessions, mark coursework and provide office hours for undergraduate students. Although students studying in European will likely contribute to these at some point during their study, this would normally be on a voluntary basis and involve less time commitment.

Research Flexibility

Another difference is project flexibility. In Europe, students typically apply to a PhD project predetermined by a supervisor, and although there may be some scope to adapt the project, depending on the funding provider , it will usually be limited to how the project is carried out rather than what it is about. In the US, however, a student applies to become a doctoral candidate within a department rather than applying for a particular research project. This is because students are expected to decide on their thesis topic (also commonly referred to as a dissertation research topic) near the end of their first phase after they have developed a better understanding of their subject and know where their interests lie. Therefore, research students in the US generally have more flexibility and influence in the direction of their research than students in the United Kingdom or Europe.

PhD Admission Requirements in USA

PhD admission into US universities can be highly competitive, both because of the limited number of positions and the large number of annual applicants.

The eligibility requirements for a doctoral program in the USA can generally be divided into four sections:

How to Apply for a PhD in USA

  • Grade Point Average ( GPA ) – in the US, a scoring system known as Grade Point Average is used to measure academic ability. A student’s GPA is calculated as a weighted score of the subjects they study during their undergraduate degree; an equivalent score is calculated by universities for international applicants. Although universities rarely set minimum GPA requirements for doctoral study, it’s worth being aware that a GPA of 3.0 is equivalent to a UK second class honours (2:1); the typical entry requirement for UK universities.
  • Graduate Records Exam (GRE) – most universities will require you to take a series of examinations known as Graduate Records Exams, which are used to determine your suitability for graduate study. GREs will assess your analytical, reasoning and critical thinking skills as well as your depth of your subject.
  • Student aptitude – in addition to academic ability, US universities also look for characteristics of a strong researcher. These include traits such as engaging in the subject in your own time, e.g. by attending talks and conferences, demonstrating a high degree of independence and enthusiasm, and a general passion for your subject.
  • English Language Proficiency – international students whose first language is not English must sit language exams such as IELTS or TOELF to demonstrate their English language proficiency.

International students will also require a F1 student visa in order to study in the US, however, you would typically apply for this after you have secured a place into a doctorate program.

How to Apply for PhD in USA

When applying for a PhD position at a graduate school, the application process will differ between universities, however, they will all typically ask for the following:

  • Academic CV – a short document summarising your educational background and current level of experience .
  • Personal statement – a document which outlines why you believe you are suitable for PhD study and your passion for the subject.
  • Academic transcripts – a complete breakdown of the modules and their respective marks you have taken as part of your previous/current degree.
  • GRE scores – a transcript of your Graduate Records Exam results.
  • Research statement – a condensed version of a research proposal outlining your general research interests, if required.
  • Recommendation letters – references from several academic referees who endorse your qualities as a person, your abilities as a student and your potential as a doctoral researcher.

Application Deadlines and Fees

Since PhD programs in the United States have taught components, they commence at the same time as all other taught degrees, and therefore share the same application deadlines and start dates. This corresponds to an application period that typically begins in August and ends in February. Admission decisions are typically made in April, with successful students starting in August/September.

When you apply to a graduate school, you will be expected to pay a fee for each doctorate application to cover the school’s administrative costs for processing your application. The fee varies from university to university, but typically ranges from $50 to $100 .

Funding your PhD in USA

It’s very common for a PhD student to receive financial aid in the form of a PhD scholarship; in fact, this will be the case for the vast majority of students in the US.

PhD funding can be ‘fully funded’ covering the student’s graduate program tuition fees, accommodation and living costs, or ‘partially funded’ covering the student’s tuition fee only in part or full.

Besides funding, a graduate student can take on an assistantship, such as a graduate teaching assistant or research assistant, in which they take on a part-time salaried position at the university alongside their studies.

Due to the international and collaborate nature of American universities, there are also a number of international scholarships available, such as the Fulbright Scholarship and the AAUW International Fellowship .

PhD Duration in USA

In the US, a PhD takes approximately 5 – 6 years to complete if studying full-time, and 8 – 10 years if studying part-time.

If you already have a Master’s degree, your first phase can be shortened by one year at the discretion of the university.

Cost of a PhD in USA

The cost of a PhD program in the US can vary considerably depending on the type of university, i.e. whether it’s a public or private university, the doctoral course, i.e. whether it’s in a STEM subject such as computer science, engineering or a non-STEM subject, and whether you are a home or international student.

In general, however, the typical annual tuition fee for a PhD in the US is between $12,000 and $45,000 per academic year.

As with any doctoral degree, additional costs may include travel for collaborations, bench fees, accommodation and living expenses.

Master's vs PhD | A Complete Guide to the Differences

Published on November 27, 2020 by Lauren Thomas . Revised on May 10, 2024.

The two most common types of graduate degrees are master’s and doctoral degrees:

  • A master’s is a 1–2 year degree that can prepare you for a multitude of careers.
  • A PhD, or doctoral degree, takes 3–7 years to complete (depending on the country) and prepares you for a career in academic research.

A master’s is also the necessary first step to a PhD. In the US, the master’s is built into PhD programs, while in most other countries, a separate master’s degree is required before applying for PhDs.

Master’s are far more common than PhDs. In the US, 24 million people have master’s or professional degrees, whereas only 4.5 million have doctorates.

The table below shows the key differences between the two.

Master’s PhD
Career prospects Usually intended for a career outside of academia. Prepares for a research career, ideally as a university professor.

how many years to get a phd degree

A PhD is right for you if:

  • Your goal is to become a professor at a university or some other type of professional researcher.
  • You love research and are passionate about discovering the answer to a particular question.
  • You are willing to spend years pursuing your research even if you have to put up with a lot of dead ends and roadblocks.

A master’s degree is the better choice if any of the following apply:

  • You want to continue studies in your field, but you’re not committed to a career as a professional researcher.
  • You want to develop professional skills for a specific career.
  • You are willing to pay a higher upfront cost if it means finishing with your degree (and thus being able to work) much faster.
  • You want the option to study part-time while working.

The length of time required to complete a PhD or master’s degree varies. Unsurprisingly, PhDs take much longer, usually between 3–7 years. Master’s degrees are usually only 1–2 years.

Length of a master’s

Master’s degrees are usually 2 years, although 1-year master’s degrees also exist, mainly in the UK.

Most of the degree consists of classes and coursework, although many master’s programs include an intensive, semester-long master’s thesis or capstone project in which students bring together all they’ve learned to produce an original piece of work.

Length of a PhD

In the US, a PhD usually takes between 5 and 7 years to complete. The first 2 years are spent on coursework. Students, even those who choose to leave without finishing the program, usually receive a master’s degree at this point.

The next 3–5 years are spent preparing a dissertation —a lengthy piece of writing based on independent research, which aims to make a significant original contribution to one’s field.

Master’s degrees tend to prepare you for a career outside of academia, while PhDs are designed to lead to a career in research.

Careers for master’s graduates

There are two types of master’s degrees: terminal and research-intensive. The career prospects are different for each.

Terminal master’s degrees are intended to prepare students for careers outside of academia. Some degrees, known as professional degrees, specifically prepare students for particular professions; these include the Master of Public Policy (MPP), Master of Business Administration (MBA), Doctor of Physical Therapy (DPT), Master of Fine Arts (MFA), and Master of Public Health (MPH) degrees.

Other master’s degrees, usually Master of Arts (MA) or Master of Sciences (MS or MSc) degrees, do not necessarily lead to a specific career, but are intended to be a final degree. Examples include an MS in Communications or MS in Data Analytics.

In research-intensive master’s programs, students take coursework intended to prepare them for writing an original piece of research known as the master’s thesis . Such programs are usually intended to prepare for further study in a doctoral program.

Careers for PhD graduates

As research degrees, PhDs are usually intended to lead to an academic career. A PhD can be thought of like an apprenticeship, where students learn from professional researchers (academics) how to produce their own research.

Most students aspire to become a university professor upon the completion of their degree. However, careers in academia are highly competitive, and the skills learned in a doctoral program often lend themselves well to other types of careers.

Some graduates who find they prefer teaching to producing research go on to be teachers at liberal arts colleges or even secondary schools. Others work in research-intensive careers in the government, private sector, or at think tanks.

Below are a few examples of specific fields and non-academic careers that are common destinations of graduates of those fields.

  • Computer Science
  • Lab Sciences

Many government jobs, including economists at a country’s central bank, are research-intensive and require a PhD. Think tanks also hire economists to carry out independent research.

In the private sector, economic consulting and technology firms frequently hire PhDs to solve real-world problems that require complex mathematical modeling.

Graduate students from the humanities are sometimes hired by museums, who can make use of their research and writing skills to curate exhibits and run public outreach.

Humanities PhDs are often well-suited to research and grant-writing roles at nonprofits. Since so much of research is funded by grants, PhD students often gain a lot of experience applying for them, which is a useful skill in the nonprofit sector.

There are a wide range of non-academic research jobs for lab scientists with doctorates in subjects like chemistry, biology, ecology and physics.

Many PhD graduates are hired by pharmaceutical companies that need to perform research to create and test their products. Government agencies, such as the Environmental Protection Agency (EPA), also hire lab scientists to work on research projects.

Job prospects after graduation vary widely based on the field. In fields like management, computer science, statistics, and economics, there’s little underemployment—even graduates from less well-known programs can easily find jobs that pay well and use the skills they’ve gained from the PhD.

However, in other fields, particularly in the humanities, many PhD graduates have difficulty in the job market. Unfortunately, there are far more PhD graduates than assistant professor roles, so many instead take on part-time and low-paid roles as adjunct instructors. Even non-academic careers can sometimes be difficult for PhDs to move into, as they may be seen as “overqualified”  or as lacking in relevant professional experience.

Because career options post-PhD vary so much, you should take the time to figure out what the career prospects are in your field. Doctoral programs often have detailed “placement” records online in which they list the career outcomes of their graduates immediately upon leaving the program. If you can’t find these records, contact the program and ask for them—placement information should play an important role in your choice of PhD program.

Prevent plagiarism. Run a free check.

Although PhDs take far longer to complete, students often receive a living stipend in exchange for being a teaching or research assistant. Master’s degrees are shorter but less likely to be funded.

Both master’s degrees and PhDs lead to increased salaries upon graduation. While PhDs usually earn a bit more than those with a master’s degree, in some fields, the wages are identical, meaning that no financial benefit is gained from going on to a PhD.

Cost of a master’s

The upfront cost of a master’s degree is usually higher than a doctoral degree due to the lower amount of financial aid available. However, increased salaries also arrive faster than with a doctoral degree, because people graduate much earlier from a master’s program.

Some master’s students do receive stipends for their degrees, usually as compensation for being a teaching or research assistant. In addition, many people complete master’s degrees part time while working full-time, which allows them to fund their living costs as well as tuition.

The cost varies significantly by school and program. Public schools are usually cheaper than private ones. Some master’s degrees, such as MBAs, are notoriously expensive, but also result in much higher wages afterwards that make up for the high cost.

The master’s wage premium , or the extra amount that someone with a master’s degree makes than someone with just a high school diploma, is 23% on average. Many universities provide detailed statistics on the career and salary outcomes of their students. If they do not have this online, you should feel free to contact an administrator of the program and ask.

Cost of a PhD

PhDs, particularly outside the humanities, are usually (though not always) funded, meaning that tuition fees are fully waived and students receive a small living stipend. During the last 3–5 years of a PhD, after finishing their coursework (and sometimes before), students are usually expected to work as graduate instructors or research assistants in exchange for the stipend.

Sometimes students can apply for a fellowship (such as the National Science Foundation Graduate Research Program in the United States) that relieves them of any obligations to be a teaching or research assistant. Doctoral programs in the US tend to be better funded than in the rest of the world.

Sometimes, PhD degrees can be completed part-time, but this is rare. Students are usually expected to devote at least 40 hours a week to their research and work as teaching or research assistants.

The main cost of doctoral programs comes in the form of opportunity cost—all the years that students could be working a regular, full-time job, which usually pays much better than a graduate school stipend.

The average wage premium for PhDs is 26%, which is not much higher than the master’s degree premium.

In the US, the application process is similar for master’s and PhD programs. Both will generally ask for:

  • At least one application essay, often called a personal statement or statement of purpose .
  • Letters of recommendation .
  • A resume or CV .
  • Transcripts.
  • Writing samples.

Applications for both types of programs also often require a standardized test. PhDs usually require the Graduate Record Examination (GRE), which tries to measure verbal reasoning, quantitative, critical thinking , and analytical writing skills. Many master’s programs require this test as well.

Applying for a master’s

Master’s degrees programs will often ask you to respond to specific essay prompts that may ask you to reflect upon not just your academic background, but also your personal character and future career ambitions.

Northwestern University’s Kellogg Business School requires Master’s of Business Administration (MBA) applicants write two essays, one about a recent time they demonstrated leadership and the second about their personal values.

Who you should ask for your letters of recommendation varies by program. If you are applying to a research-intensive master’s program, then you should choose former professors or research supervisors. For other programs, particularly business school, current work supervisors may be a better choice.

Some professional master’s programs require a specific test. For example, to apply to law school, you must take the Law School Admissions Test, or LSAT. For business school, you must take either the GRE or the Graduate Management Admissions Test (GMAT).

Applying for a PhD

When applying for a PhD, your resume should focus more on your research background—you should especially emphasize any publications you’ve authored or presentations that you’ve given.

Similarly, your statement of purpose should discuss research that you’ve participated in, whether as an assistant or the lead author. You should detail what exactly you did in projects you’ve contributed to, whether that’s conducting a literature review, coding regressions, or writing an entire article.

Your letters of recommendations should be from former professors or supervisors who can speak to your abilities and potential as a researcher. A good rule of thumb is to avoid asking for recommendations from anyone who does not themselves have a PhD.

A master’s is a 1- or 2-year graduate degree that can prepare you for a variety of careers.

All master’s involve graduate-level coursework. Some are research-intensive and intend to prepare students for further study in a PhD; these usually require their students to write a master’s thesis . Others focus on professional training for a specific career.

A PhD, which is short for philosophiae doctor (doctor of philosophy in Latin), is the highest university degree that can be obtained. In a PhD, students spend 3–5 years writing a dissertation , which aims to make a significant, original contribution to current knowledge.

A PhD is intended to prepare students for a career as a researcher, whether that be in academia, the public sector, or the private sector.

This depends on the country. In the United States, you can generally go directly to a PhD  with only a bachelor’s degree, as a master’s program is included as part of the doctoral program.

Elsewhere, you generally need to graduate from a research-intensive master’s degree before continuing to the PhD.

This varies by country. In the United States, PhDs usually take between 5–7 years: 2 years of coursework followed by 3–5 years of independent research work to produce a dissertation.

In the rest of the world, students normally have a master’s degree before beginning the PhD, so they proceed directly to the research stage and complete a PhD in 3–5 years.

A master’s degree usually has a higher upfront cost, but it also allows you to start earning a higher salary more quickly. The exact cost depends on the country and the school: private universities usually cost more than public ones, and European degrees usually cost less than North American ones. There are limited possibilities for financial aid.

PhDs often waive tuition fees and offer a living stipend in exchange for a teaching or research assistantship. However, they take many years to complete, during which time you earn very little.

In the US, the graduate school application process is similar whether you’re applying for a master’s or a PhD . Both require letters of recommendation , a statement of purpose or personal statement , a resume or CV , and transcripts. Programs in the US and Canada usually also require a certain type of standardized test—often the GRE.

Outside the US, PhD programs usually also require applicants to write a research proposal , because students are expected to begin dissertation research in the first year of their PhD.

How Long Does It Take To Get A PhD (Doctorate)?

  • In General , PHD

Doctorate Degree

As with many things in life, how long it takes you to get a PhD depends mostly on you. Because doctorate degrees are flexible, the duration of study can vary. But if you work hard and are disciplined, how long will it take you to get a PhD

Find A PhD

How long is a full-time PhD?

In most cases, PhD research involves full-time study. You should expect to dedicate around 35 hours per week to your work. However, in busy periods, such as writing up your thesis , you may need to work for considerably longer. 

In the UK,  it usually takes three to four years of full-time study to gain a PhD. Time is spent carrying out research and collecting data towards a thesis. Your thesis can take a year to write and will offer an original contribution to your subject.Once you have completed your thesis you will usually have to undertake a PhD viva to present, explain and defend your research.

Most students begin a PhD after completing a relevant masters course. A masters degree will usually take around one year to complete if you are studying full time, or two to five years if you are studying part time. So from undergraduate to doctorate, you should expect it to take at least four years full time.

In Europe, the time it takes to gain a PhD can vary depending on the country and the subject of study. For example, in Germany, a PhD in a scientific subject might take two to three years full time, and a doctorate in the arts or humanities may take four to six years full time. In Norway, all PhDs usually take three years on a full-time basis. Most countries are similar to the UK, where you complete your PhD once you have done a relevant masters course.

In Norway , all PhDs usually take three years on a full-time basis – here is a great explanation from the  University of Oslo . It can take up to six years to complete a PhD on a part-time basis, but this way of studying is unusual. 

The USA has a different university set up to the UK and Europe as most doctorate degrees are gained by going to Graduate School straight after you have completed your undergraduate degree. This means that the time it takes to gain your masters-level qualification is built into the time it takes to get your PhD. It is common for it to take four to five years to gain a Doctorate from the time you start Graduate School, but it can take up to eight years of full-time study. It depends on the institution and the type of PhD you choose.  

Some institutions, like Franklin University, allow students to transfer credits and count professional work experience towards their doctorate degrees, so you could complete a PhD in as little as three years.

How long is a part-time PhD?

Studying for a PhD part time is a good way to accommodate other work or life commitments alongside your research. Typically, it takes twice as long as a full-time PhD and you will study for around 20 hours a week.

Not many PhD students undertake their doctorate on a part-time basis, but those who do will have between five and seven years to complete their PhD. 

Part-time PhDs are unusual in Europe. In Germany, you could expect a PhD to take four to eight years. France is similar to Germany, and it takes around three to four years for a full-time doctorate in the sciences, and four to five years for a doctorate degree in the arts and humanities. At the University of Oslo, it can take up to six years to complete a PhD on a part-time basis. 

Part-time and online PhDs are more common in the USA and these take anywhere from five to 10 years to complete.

How long is a distance learning PhD?

There are some doctorate degrees which are studied by distance learning. These online PhDs allow students to study at a location and time that suits their schedule. These tend to be part time only and usually take up to seven years to complete. 

Entry requirements for a PhD

In the UK the vast majority of PhD candidates will begin a PhD after completing a relevant masters course . A masters degree will usually take around one year to complete if you are studying full time, or two to five years if you are studying part time. Once you've gained this qualification you can move onto the doctorate after you have excelled at your PhD interview.

Different countries in Europe have different traditions and regulations surrounding doctorate degrees. Most countries are similar to the UK, where you complete your PhD once you have done a relevant masters course. 

Why does it take so long to complete a PhD? 

Due to the complexity of the study and the amount of original research required, PhDs typically take longer to complete than other undergraduate degrees. It can take a long time to create a thesis, since you must make an original and noteworthy contribution to your field.

What is the deadline for finishing a PhD?

The deadline for submitting your PhD will be set by your university. In the UK, the deadline is defined by the last date on which you can submit your thesis. For most PhDs, the deadline is four years for full-time students and seven years for part-time students. It may be possible to extend the deadline up to four years, but this is at the discretion of the university. 

Does funding impact the length of a PhD? 

Generally, PhD funding providers will cover you for a set amount of time during the course of your PhD. Most students will aim to finish their PhD within the timeframe set by their funding provider to avoid incurring additional fees. 

Self-funded students cover their own tuition fees and other related costs, therefore many self-funded students aim to complete their PhDs in the shortest time possible.

Getting a Ph.D. in Psychology

Verywell / Evan Polenghi

Ph.D. vs. Psy.D.

Job opportunities, earning a degree, specialty areas, alternatives.

Getting a Ph.D. in psychology can open up a whole new world of career opportunities. For many careers paths in psychology-related career paths, a doctoral degree is necessary to obtain work and certification. A Ph.D. is one option, but it is not the only educational path that's available to reach some of these goals.

A Ph.D., or doctor of philosophy, is one of the highest level degrees you can earn in the field of psychology . If you're considering pursuing a graduate degree, you might be wondering how long it takes to earn a Ph.D. in psychology . Generally, a bachelor's degree takes four years of study. While a master's degree requires an additional two to three years of study beyond the bachelor's, a doctoral degree can take between four to six years of additional graduate study after earning your bachelor's degree.

Recently, a new degree option known as the Psy.D. , or doctor of psychology, has grown in popularity as an alternative to the Ph.D. The type of degree you decide to pursue depends on a variety of factors, including your own interests and your career aspirations.

Before deciding which is right for you, research your options and decide if graduate school in psychology is even the best choice for you. Depending on your career goals, you might need to earn a master's or doctoral degree in psychology in order to practice in your chosen field. In other instances, a degree in a similar subject such as counseling or social work may be more appropriate.

A doctorate in psychology is required if you want to open your own private practice.

If you want to become a licensed psychologist, you must earn either a Ph.D. or a Psy.D. in clinical or counseling psychology.

In most cases, you will also need a doctorate if you want to teach and conduct research at the college or university level. While there are some opportunities available for people with a master's degree in various specialty fields, such as industrial-organizational psychology and health psychology , those with a doctorate will generally find higher pay, greater job demand, and more opportunity for growth.

In order to earn a Ph.D. in psychology, you need to first begin by earning your bachelor's degree. While earning your undergraduate degree in psychology can be helpful, students with bachelor's degrees in other subjects can also apply their knowledge to psychology Ph.D. programs . Some students in doctorate programs may have a master's degree in psychology , but most doctorate programs do not require it.

After you’ve been admitted to a graduate program, it generally takes at least four years to earn a Ph.D. and another year to complete an internship. Once these requirements have been fulfilled, you can take state and national exams to become licensed to practice psychology in the state where you wish to work.

Once you enter the graduate level of psychology, you will need to choose an area of specialization, such as clinical psychology , counseling psychology, health psychology, or cognitive psychology . The American Psychological Association (APA) accredits graduate programs in three areas: clinical, counseling, and school psychology.   If you are interested in going into one of these specialty areas, it's important to choose a school that has received accreditation through the APA.

For many students, the choice may come down to a clinical psychology program versus a counseling psychology program. There are many similarities between these two Ph.D. options, but there are important distinctions that students should consider. Clinical programs may have more of a research focus while counseling programs tend to focus more on professional practice. The path you choose will depend largely on what you plan to do after you complete your degree.

Of course, the Ph.D. in psychology is not the only graduate degree option. The Psy.D. is a doctorate degree option that you might also want to consider. While there are many similarities between these two degrees, traditional Ph.D. programs tend to be more research-oriented while Psy.D. programs are often more practice-oriented.

The Ph.D. option may be your top choice if you want to mix professional practice with teaching and research, while the Psy.D. option may be preferred if you want to open your own private psychology practice.

In the book "An Insider's Guide to Graduate Programs in Clinical and Counseling Psychology," authors John C. Norcross and Michael A. Sayette suggest that one of the key differences between the two-degree options is that the Ph.D. programs train producers of research while Psy.D. programs train consumers of research. However, professional opportunities for practice are very similar with both degree types.

Research suggests that there are few discernible differences in terms of professional recognition, employment opportunities, or clinical skills between students trained in the Ph.D. or Psy.D. models. One of the few differences is that those with a Ph.D. degree are far more likely to be employed in academic settings and medical schools.

Social work, counseling, education, and the health sciences are other graduate options that you may want to consider if you decide that a doctorate degree is not the best fit for your interests and career goals.

A Word From Verywell

If you are considering a Ph.D. in psychology, spend some time carefully researching your options and thinking about your future goals. A doctoral degree is a major commitment of time, resources, and effort, so it is worth it to take time to consider the right option for your goals. The Ph.D. in psychology can be a great choice if you are interested in being a scientist-practitioner in the field and want to combine doing research with professional practice. It's also great training if you're interested in working at a university where you would teach classes and conduct research on psychological topics.

Academia Insider

Can I do a PhD after masters? How long does it take to get a PhD / Doctorate

A common question that many graduate students have is whether they can pursue a PhD after completing their master’s degree.

The answer is yes, it is possible to continue your academic career by obtaining a doctoral degree in your field of study.

There are several factors that need to be considered before embarking on this path.

This article will provide an overview of the key factors students should consider when deciding whether to pursue a PhD after completing their master’s degree.

Should I get my PhD after my masters? What about industry?

Deciding whether to pursue a PhD immediately after a master’s degree or enter the workforce first depends on personal goals, interests, and circumstances.

A PhD typically requires around five years of self-directed effort, similar to starting a business. If passionate about research, it might be best to begin right away.

Working in industry before pursuing a PhD can lead to habits that may not benefit academia and can take longer to adjust back to a scholarly environment.

Long-term relationships are essential in academia, and aggressive industry tactics might not be well-received.

Starting a PhD earlier allows for more time to produce research and establish a successful career, particularly for those considering a long-term academic path.

PhD pursuit offers flexibility in research topics and projects, enabling exploration across various subjects and building connections with professionals from different fields. This leads to unique opportunities and experiences that may not be available when working for a single company.

Considering factors like personal goals and readiness for the workload and demands of a PhD program is crucial.

Weigh the potential benefits of advancing education against the time, cost, and personal demands of a doctoral program. If a PhD aligns with one’s career aspirations and personal goals, it may be a worthwhile pursuit.

However, if the investment required outweighs the potential benefits, it might not be the best choice.

It’s always possible to try a PhD program for a year or two and then make a more informed decision based on individual experiences.

How Long Does It Take to Get a PhD or Doctorate? Time to complete everything

Leading up to getting a PhD there are many qualifications you need to get. Here is the amount of time a typical US Doctorate can take to achieve including all of the previous qualifications. It can take up to 13 years to complete

Bachelor’s Degree4 years (typical)4 years
Master’s Degree (optional)2 years (typical)6 years
PhD Coursework3 years (average)9 years
PhD Comprehensive Exams1-2 semesters9.5 years
PhD Dissertation: This is a key component of the years of study involved in a doctorate degree. Research3 years (average)12.5 years
PhD Dissertation Defense1-2 semesters13 years

The length of time to complete a PhD varies depending on several factors.

On average, in the US it takes about six years, with three years dedicated to coursework and another three years for the dissertation project.

Factors that can influence the duration include:

  • prerequisites of the program,
  • program format,
  • the student’s motivation,
  • prior knowledge,
  • Personal circumstances, such as being an international student, can influence the time it takes to complete the doctoral program.
  • Funding and scholarship stipend can significantly affect the years of study and the time it takes to earn a doctorate degree. 
  • field of study,
  • dissertation topic,
  • Support of the graduate advisor can be a crucial factor in minimizing the time it takes to complete a doctorate degree.

The range can be as short as three years or as long as seven to eight years , depending on the individual and the circumstances.

Do you need a master’s for a PhD? A shorter career path that doesn’t take so long.

In certain fields, such as clinical psychology, it is possible to pursue a PhD without obtaining a master’s degree first.

To do so, one must demonstrate a strong academic and research background, as well as a commitment to the field.

Here are the most important attributes if you are thinking about going straight into a PhD without a master’s:

  • Strong academic and research background: Ensure that you have excelled in your coursework and maintained a high GPA.
  • Undergraduate research experience: Engage in research projects during your undergraduate studies, preferably with a thesis component.
  • Clinical exposure (if applicable): Gain relevant experience in the field to showcase your practical knowledge and commitment.
  • Leadership experience: Participate in activities that demonstrate your ability to lead and work effectively within a team, as this can be advantageous in the years of study required to earn a doctorate degree.
  • Interpersonal skills: Develop strong communication and collaboration skills, which are essential for success in a PhD program.
  • Clear determination: Express your dedication to pursuing a PhD directly from your undergraduate studies, highlighting your commitment to the field and how quickly you aim to earn a doctorate.
  • Assess your certainty: Be sure that you are confident in your goals and prepared to invest the necessary effort to be competitive without a master’s degree.

By satisfying these requirements, you can better assess your eligibility to apply for a PhD without a master’s degree and potentially save time and money in the process.

Earn a Doctorate without a Masters – How Does It Work? 

Obtaining a PhD without a master’s degree is not a common path, but it is possible under certain circumstances.

Typically, a PhD candidate has an undergraduate degree with high grades, a master’s degree, and relevant research skills.

However, there are exceptions where individuals have successfully transitioned from their undergraduate studies directly to a PhD program.

One such scenario involves having a strong rapport with a potential PhD supervisor, perhaps from your undergraduate program, which can significantly reduce the time it takes to earn a doctorate.

This relationship can help compensate for the lack of a master’s degree, but it’s not a guarantee.

Another example is being an exceptional student with a first-class undergraduate degree and a dissertation closely aligned with the advertised PhD project.

Demonstrating an outstanding attitude and performance during your undergraduate project may give you an edge over other applicants.

In applied PhDs, practical experience can also be beneficial, particularly if it includes valuable contacts in the field.

For instance, if your PhD is related to professional sports and you have numerous connections within the industry, it may facilitate recruitment and collaboration, enhancing your chances of acceptance.

However, as with the other examples, this is not a sure-fire way to secure a position.

While securing a PhD without a master’s degree is challenging, it is not impossible.

The best approach is to pursue a master’s degree, as it will better prepare you for a PhD program. – Dr Andy Stapleton

Nonetheless, if you are determined to bypass the master’s route, perseverance and strategic networking can potentially lead to success.

What after Masters: MPhil or Doctorate Degree?

After completing a Master’s degree, you may be considering whether to pursue an MPhil or a PhD.

Here are the differences between the two:

LevelIntermediate research degreeHighest academic research degree
ObjectiveDevelop research skillsProduce independent research contributing to the field
Duration1-2 years (full-time)Typically take 3-7 years (full-time or part-time).
ScopeSmaller in scale and depthBroader scope and deeper engagement
Research FocusLess complex topicsMore complex topics
SupervisionSupervised researchSupervised research with more independence
TrainingLimitedResearch workshops, writing classes, group work, interdisciplinary modules
Career ImpactGood for research-oriented positionsGreater career advancement in academia and research
DissertationSmaller in scale and less comprehensiveLarger, more comprehensive, and novel research project

A PhD, being the highest academic title awarded for independent research, offers a broader scope and deeper engagement with complex topics than an MA or MPhil.

It can be thought of as an apprenticeship in planning and conducting your research.

The program duration ranges from three to seven years, depending on whether you choose to study full-time or part-time.

Entry is competitive, as candidates must demonstrate a strong track record of academic success.

PhD students attend research workshops, writing classes, and work in groups to explore each other’s studies.

They have opportunities to discuss their research across the university, in graduate school, and other classes, which can be particularly beneficial for an international student. A PhD involves a multi-year project based on independent research, with support from supervisors and training that contributes to the chosen field of study.

It’s essential to have a clear idea of the topic you want to explore in-depth and the methods you plan to employ before applying for a PhD program.

Doing a PhD can be both intellectually and emotionally demanding.

However, working in a department with dedicated and talented staff, excellent supervisors, ongoing training, and support from fellow students can make the experience enjoyable and rewarding.

It is crucial to choose the right supervisor and have a good working relationship with them, as this can significantly impact your PhD journey and the time it takes to complete it.

Wrapping up PhD programs after a masters – how long does it take to complete?

Pursuing a PhD after a master’s degree is a common path for those looking to advance in academia or research-intensive careers.

While obtaining a PhD requires a significant commitment of time and resources, it can lead to prestigious positions or high-paying jobs. It is crucial to consider personal goals, interests, and the job prospects in the field before enrolling in a doctoral program.

For those considering a PhD without a master’s degree, it is essential to demonstrate a strong academic and research background and commit to the field.

The decision between an MPhil and a PhD depends on the desired scope, depth, and career impact of the research. Ultimately, individuals should carefully weigh the potential benefits against the time it takes, cost, and personal demands of a doctoral program before making a decision.

A Brief History of Kamala Harris and Her Politics

Vice President Kamala Harris is now the obvious heir as the Democratic nominee following President Joe Biden ’s announcement that he would not seek reelection. Harris’s ascent is a remarkable turn of fate for a politician whose unpopularity has been viewed as a key reason why Biden initially decided to seek a second term. While Harris, 59, has secured major endorsements and has strong appeal with crucial voting blocs for Democrats — as the first woman of color to serve as vice president — there is still a chance others could mount challenges for the nomination.

In a Bloomberg News/Morning Consult poll conducted in early July, 46% of swing-state voters said they trusted Harris to fulfill the duties of the presidency if Biden were no longer able to serve. Some 77% of swing-state Democrats said they supported her to take over for Biden if he were unable to continue.
