Negotiating PhD Funding: What You Can Ask For

Negotiating PhD Funding: What You Can Ask For

You can negotiate a PhD funding offer, but not a base stipend set at a published rate, as Princeton's is. What can move is one specific term: summer months, guaranteed years, fees or a fellowship top-up. Ask after the offer is in writing and before you accept.

Job-offer negotiation advice tells you to name a higher number. That fails when the number is a university-wide rate that a department cannot change for one admit. A request that works is a side-by-side: your preferred offer, a real competing offer, and the one line where they differ. This page shows which lines are set, which can move, and a constructed email that asks for one of them. For the full offer-reading checklist, start with what "fully funded" means in a US PhD offer.

Every university and Council of Graduate Schools (CGS) page quoted below was checked on October 29, 2026. Stipend rates change every year, so read the current year's rate page before you write.

What is set and what is not

Set: the published rate. Princeton's Graduate School posts its stipend and salary rates for 2026-27 on its funding calendar page:

When the number is on a rate table like this, a department asking for "$3,000 more" for one person is asking the university to break its own schedule. Do not spend your one request there.

Set: the guarantee, and its condition. MIT EECS's admissions FAQ says: "In the EECS PhD program, students are fully funded throughout the duration of their graduate program, assuming satisfactory progress in their research and in their academic PhD milestones." Carnegie Mellon's Computer Science Department says it "offers all admitted Ph.D. students comprehensive financial support (stipend, tuition, university student fees, university student health insurance; please see links below) while they are in good academic standing in their respective programs" (CMU CSD doctoral admissions). There is nothing to negotiate in a promise that already covers every admit.

Not set: the mix of sources. MIT EECS also says "Decisions on support are made after decisions on admission" and that "Any newly admitted student will automatically be considered for Department fellowships and assistantship support." Which source pays you (a fellowship, a research assistantship or a teaching assistantship) and in which year is decided per student. That mix decides your summer, your teaching load and what happens if a grant ends. It is also where a department has room.

Unknown: how often packages change. No university we checked publishes how many admits ask, or how many get a changed package. We have no data on it either. Treat any claimed success rate as unsourced.

Our view: in a program with a published rate and a funding guarantee, negotiate terms, not the stipend. Ask about summer, years, fees or a top-up, and only with a written competing offer that beats your preferred offer on that exact term. The countercase: if a program publishes no rate table, gives no multi-year guarantee, or funds you from one professor's grant, the package is less fixed. There, a direct question about the stipend itself is reasonable. And if you hold only one offer, you have no side-by-side, so ask questions, not for changes.

The four terms that can move

These are lines where two offers can differ and where a department may have discretion. Each one links to a page that goes deeper.

1. Summer months. A 10-month assistantship plus a line saying summer support is typical is not a 12-month promise. Princeton lists summer research pay as its own two-month line. See nine-month versus twelve-month PhD funding.
2. Guaranteed years and the condition. A fixed "five years" and CMU's "while they are in good academic standing" are different promises. Ask what happens after year five if you are still making progress.
3. Fees and health insurance. A tuition waiver can leave mandatory fees. CMU names fees and health insurance in its support sentence; not every letter does. See why fees remain after a tuition waiver.
4. Fellowship top-ups and outside awards. First-year fellowships, recruitment supplements and how an outside fellowship combines with department money. MIT EECS asks students with an outside fellowship to contact the department "to discuss the Department policy on merging various sources of support". See whether you can stack PhD funding awards.

When to ask, and by when

The window is short. At MIT, "Decisions on financial aid are mailed between late February and April 1" and "Applicants have until April 15 to notify MIT of their decision to accept or decline the offer of admission" (MIT EECS FAQ, no cycle year stated). MIT EECS adds that "Faculty members will not discuss financial support or thesis supervision with a student who has not yet been admitted." So there is nothing to negotiate until the admission and the funding letter both exist.

The end of the window is your acceptance. The CGS April 15 Resolution says: "Acceptance of an offer of financial support*, such as full tuition support, a fellowship, traineeship or assistantship, completes an agreement that both student and graduate school are expected to honor." Ask before you accept, not after. Whether April 15 applies to your offer at all is covered in whether April 15 applies to your grad offer. If you need time for a second offer to arrive, see how to ask for more time on a PhD offer.

Build the side-by-side first

Put both written offers in one table before you write anything. Use the letters' own wording. The request is the one row where your competing offer is clearly better.

Constructed example: two offers side by side

Constructed example, written by us. The programs and amounts are invented and are not any university's package.

The academic-year stipends are close, and A's is higher, so there is nothing to ask for on that line. The real gap is summer: B promises $8,000 a summer in writing and A promises nothing. Fees are a second gap, but ask one thing. Summer is the larger and clearer one, so that is the request.

Constructed example: the email to Offer A

Constructed example, written by us, not a real applicant's email. 147 words, including the subject line and sign-off.

Subject: PhD admission, funding question before my decision

Dear Dr. Okafor,

Thank you again for the offer of admission and funding. Your program is my first choice, and I would like to accept.

One term is holding me back. My offer from you describes summer funding as "usually available." I also hold an offer from another program that guarantees an $8,000 summer research stipend in each of years one to five, in writing. I can share that letter if it helps.

Is it possible to confirm summer support for my first year, or to describe how summer funding has been decided for recent students in my area? A written answer on summer would let me decide quickly.

I plan to respond to both programs by April 5, 2027, which is before the April 15 deadline in your letter. Thank you for considering this.

Best regards, Ananya Rao

Why it works: it names the preferred program, quotes the exact line in question, names one term and the competing number, offers the letter, asks a yes-or-no question with a fallback, and gives a date. It does not mention the stipend, rank or a threat to walk away.

Who to send it to

Send it to one person: the graduate program coordinator or director of graduate studies named in your offer letter, unless the letter tells you to contact someone else. If a professor recruited you, tell them in one line that you have asked the program about summer support. Do not send separate requests to the professor and the office: two people may answer differently, and you then have two answers to reconcile.

What not to do

• Do not invent or inflate an offer. You may be asked for the letter. If you cannot send it, do not cite it.
• Do not use an offer you would never accept. Our view: a competing offer is only a fair lever if you would actually go there.
• Do not set an ultimatum. "Match this or I decline" ends the conversation. A question gets an answer.
• Do not bundle every gap. Four requests read as dissatisfaction. Pick the one row that matters most.
• Do not wait until April 15. The program needs time to answer, and a late answer leaves you no time to decide.
• Do not negotiate after you accept. CGS calls acceptance an agreement both sides "are expected to honor".

Questions about negotiating PhD funding

Can you negotiate a PhD stipend?

Not where it is a published rate. Where a university publishes a rate table, as Princeton does for 2026-27, the base stipend is set, so ask about summer, years, fees or a fellowship top-up instead. Where no rate is published, a direct question about the stipend is reasonable.

Do you need a competing offer to negotiate a PhD offer?

To ask for a change, yes, in our view. Without one you have no side-by-side to point to. You can still ask questions: how summer has been funded for recent students, which fees are covered, what happens after the guaranteed years.

Will negotiating make the program withdraw my offer?

We found no university page that says a polite funding question affects an offer, and no data on it. Missing a check-in deadline is different: the CGS FAQ says "Failure to do so may result in withdrawal of the offer of financial support." Answer every dated check-in, even while you wait for a reply.

When is the best time to negotiate PhD funding?

After both offers are in writing and before you accept. For US fall entry at a program that follows the April 15 Resolution, that is between your funding letter and April 15, 2027, a Thursday. If the funding comes from one professor's grant, check the advisor's grant end dates before you negotiate.
