Understanding PhD Funding: The Basics

What Does PhD Funding Cover?

PhD funding typically comes as a comprehensive package that includes:

Tuition Coverage: Most funded programs waive tuition fees entirely. For instance, Stanford GSE offers all admitted PhD students a five-year funding package that provides tuition aid, fellowship stipend, and assistantship salary which covers the standard cost of attendance.

Living Stipend: This is your regular income for living expenses. According to recent data, the minimum stipend for UKRI-funded doctoral students for 2025-2026 is £20,780 per year (tax-free). In the United States, stipends typically range from $20,000 to $40,000 annually depending on the field and institution.

Health Insurance: Many programs include comprehensive health coverage. For example, Cornell provides Cornell individual student health insurance for students on full assistantships.

Additional Benefits: Some programs offer travel grants, research allowances, and emergency funds for unexpected expenses.

How Long Does Funding Last?

Funding duration varies by program and country. The NSF Graduate Research Fellowship provides three years of support over a five-year fellowship period, while many university-funded packages cover five to six years of doctoral study.

Major PhD Funding Sources

1. University-Funded PhD Programs

Many top universities offer comprehensive funding packages directly to admitted students. This is perhaps the most straightforward funding path.

How It Works:

When you’re admitted to a fully-funded PhD program, the university commits to supporting you throughout your degree. Many universities offer ‘full-ride’ PhD scholarships that cover tuition fees and living expenses.

Top Universities with Full Funding:

Stanford University: Offers comprehensive five-year funding packages
Yale University: Provides full coverage for domestic and international students
University of Chicago: Offers funding for up to eight years in some programs like anthropology
Princeton University: Guarantees full funding from day one for all PhD students

Application Strategy:

Most universities don’t require separate funding applications. Simply apply to the PhD program, and if admitted, you’ll automatically be considered for funding packages. However, acceptance rates at top programs can be competitive, often below 10%.

2. Teaching Assistantships (TAs)

Teaching assistantships represent one of the most common funding sources for PhD students. They offer a win-win situation: you gain valuable teaching experience while earning your stipend.

What Teaching Assistants Do:

Graduate teaching assistants assist the delivery of content to undergraduate or Masters students, helping with tasks such as marking exams, lab demonstrations, tutorial support and tutorial delivery.

Pay and Hours:

According to recent data, in 2025-26, teaching assistants can expect to earn at least £20,780 per year (tax-free), though rates typically range between £15 and £30 an hour. In the United States, the University of Utah provides teaching assistantships with a $28,500 salary plus tuition benefits and subsidized health insurance.

Most TA positions require 15 to 20 hours per week, averaging no more than 15 hours per week.

Benefits Beyond Money:

Teaching assistantships allow students to enhance their communication, organizational, and leadership skills, all of which are transferable to various career paths. Additionally, the experience looks excellent on your CV, particularly if you’re considering an academic career.

How to Apply:

Once accepted onto a PhD program, you can apply to any teaching assistant positions on offer, which are usually circulated by email to all PhD students in the department.

3. Research Assistantships (RAs)

Research assistantships focus on supporting faculty research projects. They’re particularly common in STEM fields where professors have substantial research grants.

Key Differences from Teaching:

A research assistant is an academic appointment for research that is not directly thesis-related, with RAs spending 15 to 20 hours per week. Meanwhile, Graduate Research Assistants (GRAs) work on thesis-related research.

Funding Sources:

Research assistantships are funded by faculty research grants, other faculty funds or as needed, by the GSE Dean’s Office, and can lead to joint publications with faculty or to dissertation topics.

Benefits:

Research assistantships offer direct exposure to cutting-edge research, potential co-authorship opportunities, and deep engagement with your field. You’ll work closely with established researchers, building networks that can benefit your career.

4. Federal and Government Grants

Government-funded research grants provide prestigious, portable funding that follows you to any eligible institution.

NSF Graduate Research Fellowship Program (GRFP) – United States

The NSF GRFP is one of the most prestigious fellowships for STEM PhD students.

Award Details:

Industry partnerships offer an exciting alternative path, allowing you to maintain employment while pursuing your doctorate.

How It Works:

The Northeastern University Industry PhD pathway allows employees to pursue their PhD degree while continuing to work full time, with the employer entering into an Academic Partnership Agreement that includes an annual administrative fee covering tuition and certain fees.

Benefits:

The Academic Partnership Agreement permits the student/employee to continue working full-time and to engage in use-inspired research that is aligned to the employer’s business.

Geographic Trends:

In Germany, about 16% of all doctoral students took up a company-based PhD in 2013, and about 60% of research and development in Europe is conducted at companies instead of universities.

Career Outcomes:

Students who take part in industrial doctorate programs usually are highly demanded and valued by employers, with many able to access the labor market shortly after finishing their PhD.

Considerations:

While industry PhDs offer excellent practical experience, they may come with publication restrictions due to intellectual property concerns. Additionally, some companies require confidentiality agreements.

7. University-Specific Scholarships and Fellowships

Beyond general funding, many universities offer specialized scholarships.

Typical Packages:

Many STEM PhD programs offer five-year funding packages including tuition waiver, stipend ($25,000-$40,000), health insurance, and research support.

Humanities and Social Sciences

While funding is less abundant than STEM, strong programs still offer full support.

Common Funding Sources:

Teaching assistantships (more prevalent than in STEM)
University fellowships
External fellowships (SSRC, Fulbright-Hays, etc.)
Dissertation completion grants

Strategies:

Consider applying to multiple external fellowships, as competitive humanities programs often require students to secure some external funding.

Professional Doctorates (Education, Business, etc.)

Professional doctorate funding varies significantly.

EdD Programs: Often offer graduate assistantships and fellowship opportunities, though funding may be less comprehensive than research PhDs.

DBA Programs: Typically offer less funding than traditional business PhDs, with many students self-funding or using employer tuition benefits.

How to Maximize Your Funding Opportunities

Start Early

Begin researching funding options at least 12-18 months before you plan to start your PhD. Many major fellowships have fall deadlines for the following academic year.

Cast a Wide Net

Don’t rely on a single funding source. Apply to:

Multiple PhD programs with good funding reputations
External fellowships (2-3 opportunities)
Discipline-specific scholarships
Diversity fellowships if applicable

Craft Strong Applications

For Fellowships:

Clearly articulate your research vision
Demonstrate how your work addresses significant questions
Show broader impacts beyond your immediate field
Get feedback from advisors and peers

For Assistantships:

Highlight relevant experience (teaching, tutoring, research)
Emphasize your communication and organizational skills
Express genuine interest in mentorship and education

Understand Tax Implications

The stipend is considered taxable income by the IRS, though tuition waivers are not taxed. International students should check their home country’s tax treaty with the host country.

Negotiate When Appropriate

If you receive multiple offers, don’t be afraid to mention competing packages. Many programs have some flexibility to match or improve offers for strong candidates.

Plan for Summer Funding

Most stipends cover nine months (academic year). Investigate:

Summer teaching opportunities
Research grants from your department
External summer research fellowships
TA or RA positions during summer terms

Special Considerations for International Students

Visa Implications

Fulbright grantees enter the United States on an exchange visitor (J-1) visa under a Department of State program, which requires them to return to their home countries for a minimum of two years at the end of the grant period.

Limited vs. Unlimited Opportunities

Private universities don’t distinguish between domestic and international students, while public universities differentiate fees for in-state and out-of-state students, so international students pay the same as out-of-state domestic students.

Application Fee Waivers

Many universities offer application fee waivers for international students who can demonstrate financial need. Contact graduate admissions offices well before deadlines.

Timeline Considerations

International students need extra time for visa processing, credential evaluation, and English language testing. Plan accordingly.

Red Flags to Watch For

Unfunded or Partially-Funded Offers

If a PhD program doesn’t offer full funding, consider it carefully. This often indicates:

The program may not be well-established
You might struggle financially
The program may not value doctoral education appropriately

Unclear Funding Duration

Always clarify how many years of funding are guaranteed. Avoid programs with vague commitments or funding contingent on annual renewal without clear criteria.

Excessive Work Requirements

Standard assistantships require 15-20 hours weekly. Be wary of positions demanding significantly more, as this can impede dissertation progress.

Managing Your PhD Finances

Living on a Stipend

Most PhD stipends are designed for modest living. Consider:

Housing: Many students share apartments or live in graduate housing
Budgeting: Track expenses and prioritize necessities
Additional Income: Some students take on limited tutoring or consulting work within university guidelines

Emergency Funds

Many institutions offer emergency funds, such as the GSE Student Emergency Fund which assists graduate students who experience a financial emergency or unanticipated expenses causing financial hardship.

Dissertation Support

GSE Dissertation Support Grants help advanced PhD students who require additional financial support for dissertation research activities, available at up to $6,500 total per student.

Frequently Asked Questions (FAQs)

1. Can I work outside my PhD program while on a stipend?

Most programs allow limited outside work (typically up to 10 hours per week), but check your funding agreement. Graduate students may assume a secondary hourly role up to 5 hours per week, but may not exceed a combined total of 20 hours a week working at the university.

2. What if I don’t get funding in my first year?

Some programs offer admission without funding, expecting students to secure support later. While possible, this is risky. Consider deferring admission to reapply for funded positions, or look at programs with guaranteed funding.

3. Are PhD stipends really tax-free?

It depends. In the UK, the stipend is usually non-taxable and does not need to be paid back. However, in the United States, stipends are considered taxable income. Check your specific country’s tax laws.

4. How competitive are major fellowships like NSF GRFP?

Very competitive, with acceptance rates typically around 10-15%. However, you can apply multiple times (as an undergraduate senior and early in your PhD), so don’t be discouraged if you don’t succeed initially.

5. Can I change advisors or programs after accepting funding?

The NSF fellowship is portable and can be transferred to a different institution of higher education if a fellow chooses to transfer to another institution after completion of the first fellowship year. University funding policies vary—always check your specific agreement.

6. What happens if I take longer than the funded period to finish?

This varies by program. Some offer extensions, others require you to secure alternative funding or go without stipend while finishing. Discuss completion timelines with advisors early.

7. Do international students have equal access to funding?

At private universities, yes. Private universities don’t distinguish between domestic and international students for funding. Some public universities and government grants may prioritize domestic students. Additionally, up to 15% of CGRS D awards will be available to international applicants.

Conclusion

Funding your PhD is absolutely achievable with proper research and planning. Remember, doctoral education differs fundamentally from undergraduate study—you’re not just a student; you’re a junior researcher contributing to your field. Most quality PhD programs recognize this by offering comprehensive funding packages.

The key is to start early, apply strategically, and remain persistent. Whether through university funding, teaching assistantships, prestigious fellowships, or industry partnerships, there’s likely a path that fits your situation and goals.
