An NIH F32 grant is the Ruth L. Kirschstein National Research Service Award for individual postdoctoral fellows. It funds up to three years of mentored research training in a health-related field for a US citizen or permanent resident holding a doctoral degree, paying a stipend that starts at $63,900 in FY2026 and carrying a service-based payback obligation once the award ends.
An F32 is an individually awarded National Research Service Award (NRSA) fellowship: unlike an institutional T32 training grant, the fellow — not the institution — is the named recipient, and the fellow selects the sponsoring mentor before applying.

What is the NIH F32 postdoctoral fellowship?
The F32 activity code funds the Ruth L. Kirschstein NRSA Individual Postdoctoral Fellowship. According to the NIH activity code definition, its purpose is “to provide postdoctoral research training to individuals to broaden their scientific background and extend their potential for research in specified health-related areas.” The award covers a fellow stipend, a fixed institutional allowance and partial tuition support, and it runs for up to three years, non-renewable.
Because the F32 is awarded to the individual, the fellow drives the application: choosing a sponsor, a host institution and a research training plan, then submitting it to the relevant NIH institute under the current F32 parent funding announcement.
Who is eligible for an NIH F32 grant?
F32 eligibility rules are stricter than many NIH mechanisms because the award is an NRSA fellowship funded under the Public Health Service Act. Applicants must be US citizens or permanent residents at the time of award — a requirement that does not apply to every NIH career-development mechanism.
- Hold a research or clinically qualifying doctoral degree (Ph.D., M.D., D.D.S., D.V.M., or equivalent) from an accredited institution.
- Secure a position and a named sponsor or co-sponsor at an eligible domestic public, private or non-profit institution with the research resources to support the proposed training.
- Apply early in the postdoctoral period; several NIH institutes, including the National Institute of Mental Health, recommend applying within the first three years of postdoctoral status.
- Not hold, and not have held, an independent research grant (such as an R01) or an equivalent NIH career award at the time of the F32 application.
Applicants who have already used postdoctoral T32 institutional training support are still eligible for an F32, but the National Institute on Aging notes that “postdocs who have not been supported by a postdoctoral T32 may request the full 3 years of F32 funding,” meaning prior T32 time is generally netted against the three-year F32 ceiling.
How much does the NIH F32 pay in FY2026?
The F32 stipend is a fixed NIH-wide scale set annually and tied to years of relevant postdoctoral experience, not to the fellow’s home institution’s salary structure. For fiscal year 2026, NIH’s Kirschstein-NRSA postdoctoral stipend levels are:
| Years of postdoctoral experience | FY2026 annual stipend |
|---|---|
| 0 years | $63,480 |
| 1 year | $63,900 |
| 2 years | $64,380 |
| 3 years | $66,948 |
| 4 years | $69,180 |
| 5 years | $71,748 |
| 6 years | $74,424 |
| 7+ years | $77,076 |
Beyond the stipend, the National Cancer Institute’s F32 guidance confirms an institutional allowance of up to $12,400 annually at non-federal institutions, intended to defray research supplies, travel to scientific meetings and health insurance. The fellowship additionally covers 60% of actual tuition and fees, up to $4,500 per year, rising to $16,000 per year for fellows enrolled in a formal degree-granting programme, plus up to $3,000 per year toward childcare from a licensed provider.
F32 applications are accepted on three standard annual due dates: 8 April, 8 August and 8 December, shifting to the next business day when a deadline falls on a weekend.
What are the NRSA payback requirements for F32 recipients?
The payback obligation is the governance feature that most distinguishes NRSA postdoctoral fellowships from ordinary NIH research grants. It applies only to postdoctoral NRSA support — predoctoral F31 fellows incur no service payback obligation, while postdoctoral F32 and T32 trainees do.
Under the NRSA payback regulations at 42 CFR Part 66, the first 12 months of postdoctoral NRSA support trigger a service obligation equal in length to the funded period. A fellow satisfies it through health-related research, teaching or other approved activity, or by completing a second NRSA-supported year, which fulfils the obligation month-for-month. A fellow who takes only one year and then leaves qualifying activity must repay that year’s stipend.
- Fellows with an active payback obligation must keep NIH informed of their current address.
- They must submit an Annual Payback Activities Certification Form each year until the obligation is discharged.
- The obligation attaches to the individual fellow, not the sponsoring institution, and travels with them if they change employer.
Because 42 CFR Part 66 governs postdoctoral NRSA support generally, the same payback mechanics apply to postdocs funded through T32 institutional training grants — payback is an NRSA-wide rule, not an F32-specific penalty.
F32 vs T32: how does the individual fellowship differ from an institutional training grant?
Both are Kirschstein-NRSA mechanisms and both carry the same payback obligation for postdoctoral trainees, but their governance differs sharply in who holds the award and who selects the trainee.
| Feature | F32 (individual fellowship) | T32 (institutional training grant) |
|---|---|---|
| Award recipient | The individual postdoctoral fellow | The institution |
| Who selects the trainee | Fellow self-applies with a chosen sponsor | Institutional programme director selects trainees each year |
| Application authorship | Written primarily by the fellow, with sponsor input | Institution submits and renews; trainee has limited authorship role |
| Maximum duration | Up to 3 years, non-renewable | Institution-level award (typically 5 years); individual trainee slots usually 1-2 years |
| NRSA payback obligation | Applies (postdoctoral support) | Applies (postdoctoral support) |
| Citizenship requirement | US citizen or permanent resident | US citizen or permanent resident |
In practice, institutions use T32 slots while a research plan matures, then move the trainee to an individual F32 once that plan is well developed, since F32 review rewards a fully specified, fellow-authored training plan.
Answer-first Q&A: common F32 questions
What is an NIH F32 grant?
An NIH F32 grant is the individual Kirschstein-NRSA postdoctoral fellowship that funds up to three years of mentored research training in a health-related field. It is awarded directly to the fellow, who must hold a qualifying doctoral degree and a named institutional sponsor before applying.
What is the difference between F32 and K99?
An F32 funds mentored training only, with no independent-research phase and a strict US citizen/permanent-resident requirement. A K99/R00 Pathway to Independence award funds a shorter mentored phase followed by an independent faculty-level R00 phase, and does not require US citizenship.
How much is an F32 grant?
The FY2026 stipend ranges from $63,480 for an entry-level postdoc to $77,076 for a fellow with seven or more years of experience, plus a $12,400 annual institutional allowance and partial tuition and childcare support layered on top.
Who is eligible for F32?
US citizens and permanent residents holding a qualifying doctoral degree, who have secured a sponsor and institutional home and have not yet held an independent NIH research award, are eligible to apply for an F32.
Implications for research administrators and institutions
Institutional research administration offices should track F32 and T32 postdocs identically for NRSA payback-compliance purposes, since 42 CFR Part 66 applies to both mechanisms, not F32 alone. Offices should verify doctoral-degree completion, citizenship status and sponsor eligibility before submission, since a late-discovered gap after award can trigger a rescission — and flag the T32-to-F32 sequencing pattern early, since a postdoc who has already drawn two years of T32 support typically has only one remaining F32 year under the shared three-year NRSA ceiling.
Outlook: what this means for postdoctoral funding strategy
With T32 slots capped and competitive, the individually awarded F32 remains the most accessible NRSA route for postdocs whose institution has no open training-grant slot in their field. Institutions that build early support around F32 mentorship — helping fellows identify sponsors and draft plans before the April, August or December deadlines — turn a citizenship-restricted, payback-bound award into a reliable bridge toward independent funding such as a K99/R00 or an R01.
