The two primary types of graduate degrees are a master’s degree and a doctoral degree (PhD). A master’s is a 1-2 year program focused on advanced knowledge and skills in a specific field, preparing students for professional careers across various industries. In contrast, a PhD degree, also known as a doctorate degree or Doctor of Philosophy, is a 3-7 year research-intensive degree aimed at training individuals for academic and research careers, where they can contribute original knowledge through a dissertation.
Master’s degrees are far more common, reflecting their broader appeal and accessibility. Around 24 million people in the US hold master’s or professional degrees, while only 4.5 million have doctorates or PhDs. This disparity highlights how master’s programs cater to many professional aspirations beyond academic research. Additionally, in the US, master’s degrees are often integrated into PhD programs, with students earning a master’s before proceeding to the dissertation stage.

Which is right for you?
Choosing between a master’s degree and a PhD is a personal decision that your long-term goals, interests, and career aspirations should guide. Consider the following factors:
Career Goals: If you aspire to work in academia, conduct independent research on a specific subject, or hold leadership roles, a PhD may be the better choice. If you’re interested in advancing your professional skills or pursuing a specific career path, a master’s degree could be sufficient.
Interests and Passion: A PhD requires an immense commitment to research and a deep passion for your field. If you’re driven by intellectual curiosity and a desire to contribute new knowledge to a particular research field, a PhD may be the right path. If your interests are more professionally oriented, a master’s degree could be a better fit.
Time and Financial Resources: PhD programs are longer and often require significant financial investment and a willingness to delay earning potential for several years. Master’s programs are typically shorter and may provide quicker returns on your investment.
Length of time required
One of the most significant differences between a master’s degree and a PhD is the time commitment required for each program.
Length of a master’s
Most master’s programs can be completed in one to two years of full-time study. The exact duration may vary depending on the field of study, the program structure, and whether you pursue a thesis or non-thesis option.
- Non-thesis or coursework-only master’s programs can often be completed in one year of full-time study or two years of part-time study.
- Thesis-based master’s programs typically require two years of coursework and research, culminating in a thesis or research project.
Length of a PhD
Earning a PhD is a multi-year endeavor that requires extensive research, coursework, and a dissertation that makes a significant original contribution to your field. The average PhD program takes three to seven years to complete, with some disciplines requiring even longer commitments.
- The first two to three years are typically dedicated to coursework, qualifying exams, and developing a research proposal.
- The remaining years are focused on conducting original research, writing the dissertation, and defending it before a committee.
Note: The length of a PhD program can vary significantly depending on the field of study, the institution, and the individual student’s progress and research focus.
Career prospects
The career paths and opportunities available to master’s and PhD graduates can differ substantially, making it crucial to consider your long-term goals when choosing between the two degrees.
Careers for master’s graduates
Master’s degrees can be broadly classified into terminal and research-intensive, each offering distinct career prospects for graduates.
Terminal master’s degrees equip students with advanced knowledge and skills for professional careers outside academia. Some of these are professional degrees, specifically tailored to prepare individuals for particular professions. Examples 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).
Other terminal master’s degrees, such as the Master of Arts (MA) or Master of Science (MS or MSc), provide a comprehensive education in a specific field without necessarily leading to a specific career path. These degrees, like an MS in Communications or an MS in Data Analytics, are intended to be the final academic credential for students seeking to enhance their knowledge and expertise in a particular area.

Research-intensive master’s degrees are often viewed as stepping stones toward doctoral programs. They equip students with the foundational research experience and academic credentials required for admission to PhD programs in their respective fields.
Careers for PhD graduates
PhD programs are designed as research-intensive degrees, primarily geared towards preparing students for academic careers. A PhD can be viewed as an apprenticeship, where students learn from experienced researchers (academics) and develop the skills to conduct and produce their own original research.
For most PhD students, the ultimate goal is to secure a university professor position upon completion. However, the path to an academic career is highly competitive, and the specialized research skills acquired during a doctoral program often open doors to a broader range of career opportunities.
Beyond academia and research-focused roles, the analytical, critical thinking, and problem-solving abilities cultivated during a PhD program are transferable to various industries and sectors. PhD graduates may find rewarding careers in fields such as consulting, policymaking, or leadership roles in major corporations’ research and development departments.
Costs and salaries
The financial implications of pursuing a master’s degree versus a PhD are significant and should be carefully considered.
