Average PhD Stipend in 2026: Amounts by Country, Field & Cost-of-Living Gap (Sourced Data)
The average PhD stipend varies so dramatically by country, field, and institution that a single headline number obscures more than it reveals. A doctoral researcher on a US National Science Foundation Graduate Research Fellowship receives $37,000 per year in stipend — while a humanities PhD student at a smaller American university might receive barely $20,000 for the same calendar year. Across borders, the divergence is even sharper: a UK UKRI-funded student will receive £20,780 in 2025–26, while a Canadian tri-agency CGRS-D awardee collects CA$40,000. This guide compiles verified figures from the funding bodies themselves, flags where gaps between stipend and living wage are widest, and maps the trend lines shaping doctoral compensation in 2026.
Every figure in this article is attributed to a named source and year. Where 2026 rates are not yet published, the most recent available figures are used and labelled accordingly. No estimate is presented without a traceable origin.
United States: NSF GRFP and the National Average
The US has no single national PhD stipend. Funding flows through federal fellowship programmes, institutional grants, and teaching or research assistantships, producing a wide band of outcomes depending on field and institution.
The flagship federal fellowship is the National Science Foundation Graduate Research Fellowship Program (NSF GRFP). For 2025–26, the GRFP pays a $37,000 annual stipend plus a $16,000 Cost of Education allowance per year for each of the three funded years — a total of $159,000 per fellowship. The $37,000 rate is documented in the NSF GRFP programme solicitation published on NSF.gov in September 2025.
Beyond the GRFP’s premium tier, the real-world average diverges significantly. The PhD Stipend Survey — a crowdsourced database at phdstipends.com — places the average US PhD stipend at approximately $30,904 across surveyed institutions, against an average local living wage for those same locations of $38,939. That represents a structural shortfall of roughly 21% before rent is paid.

United Kingdom: UKRI Rates for 2025–26 and 2026–27
UK Research and Innovation (UKRI) sets a mandatory minimum stipend for all its funded PhD studentships. The 2025–26 minimum — effective from 1 October 2025 — is £20,780 per year for students outside London, with a £22,780 rate for London-based students (a £2,000 London weighting). UKRI described the increase as “the largest real-terms increase in the stipend since 2003,” according to its official announcement on ukri.org.
For 2026–27, UKRI has confirmed a further 4.9% uplift, taking the minimum to £21,805 outside London and £23,805 in London from 1 October 2026, as reported by Research Professional News and corroborated by multiple university HR pages.
| Academic Year | Outside London | London Weighting | Source |
|---|---|---|---|
| 2025–26 (from 1 Oct 2025) | £20,780 | £22,780 | UKRI.org |
| 2026–27 (from 1 Oct 2026) | £21,805 | £23,805 | Research Professional News, Feb 2026 |
Individual universities and research councils may pay above this minimum; the UKRI figure is a floor, not a ceiling.
Australia: Research Training Program Stipend 2026
The Australian Government’s Research Training Program (RTP) funds doctoral stipends through universities, which have discretion to set rates at or above the government’s indexed minimum. For 2026, full-time RTP stipend rates across major institutions range from approximately AU$35,656 per year (Griffith University, 2026) to AU$39,500 (University of Melbourne, 2026). QUT’s published 2026 rate is AU$37,010, compared with AU$33,637 in 2025 — a substantial year-on-year increase reflecting the government’s indexation decision. For comparison, part-time students receive 50% of the relevant full-time rate.
The RTP stipend is tax-exempt for domestic PhD students undertaking full-time research (Australian Taxation Office ruling), meaning the nominal figure is close to the take-home amount.
Canada: CGRS-D at CA$40,000
Canada’s tri-agency doctoral scholarship — the Canada Graduate Research Scholarship – Doctoral (CGRS-D), administered jointly by SSHRC, NSERC, and CIHR — was increased to CA$40,000 per year for three years effective September 2024, following a federal announcement in May 2024. The previous rate had been significantly lower; the increase was framed by the Government of Canada as a major investment in retaining domestic research talent.
The CGRS-D is competitive: candidates may apply a maximum of three times and must not have previously held a tri-agency doctoral award. Fields span natural sciences, engineering, health research, and social sciences and humanities, with the same dollar value across all disciplines.
Germany: TV-L E13 Contracts vs DFG/DAAD Stipends
German doctoral funding takes two main forms, with meaningfully different income levels:
- Salaried positions (TV-L E13, 50–65% FTE): Most German PhD positions are employment contracts under the collective agreement TV-L at pay group E13. A 50% E13 Step 1 position yields approximately €2,001 gross/month, translating to roughly €1,370 net/month for a single person in tax class 1 (lohntastik.de net salary calculator, 2026 rates). Step and tax-class variations can push net pay to approximately €1,800/month for those in later career steps or favourable tax circumstances.
- Stipend-based funding (DFG Research Training Groups / DAAD): The German Academic Exchange Service (DAAD) doctoral scholarship is set at €1,200 per month for doctoral candidates (DAAD scholarship database, current rates). These stipend payments are generally tax-free but do not accrue pension entitlements, making long-term financial comparison with employment contracts complex.
PhD Stipends by Field: STEM vs Humanities
The most consistent predictor of PhD stipend level within any single country is discipline. In the United States, STEM programmes (science, technology, engineering, and mathematics) offer typical assistantship stipends in the range of $28,000–$45,000 per year, while humanities and social sciences programmes cluster between $20,000–$35,000 (ApplyKite, 2026; phdstipends.com survey data). The gap — roughly $5,000–$15,000 annually — reflects the relative abundance of external grant funding available to STEM supervisors, who can buy out student stipends from research grants.
A similar pattern holds in the UK, where STEM students are more likely to hold UKRI-funded studentships (guaranteed at the minimum rate) while arts and humanities doctoral students more frequently rely on departmental bursaries, graduate teaching assistantships, or self-funding. In Germany, engineering and natural science PhD students are almost universally employed on E13 contracts; humanities doctoral students are more likely to hold DAAD or foundation stipends at lower rates.
“STEM fields command higher stipends than the humanities and social sciences, largely because there is often more grant funding available for research.” — ApplyKite PhD Student Salary Guide, 2026
The Cost-of-Living Gap: When the Average Isn’t Enough
Nominal stipend figures matter less than purchasing power. According to the PhD Stipend Survey (phdstipends.com), only approximately 10% of US universities offer doctoral stipends that exceed the local cost of living for their county. The average local living wage across surveyed institutions is $38,939 per year, while the average stipend sits at $30,904 — a deficit of roughly 21% before any discretionary spending. The shortfall is most acute in high-cost metros: Stanford’s graduate stipend of $48,216 still trails Santa Clara County’s estimated living wage of $55,860, as noted by Rice University’s Graduate and Postdoctoral Studies office.
The UK picture is comparable. London doctoral students on the UKRI minimum of £22,780 (2025–26) face a city where the London Living Wage Foundation pegs the real living wage at £13.85/hour (2024–25) — approximately £27,700 for a 38.5-hour week — placing UKRI’s London-weighted stipend roughly 18% below a standard full-time equivalent living wage. For city-level cost-of-living statistics across countries, the companion dataset at tesify.app/phd-stipend-cost-of-living-statistics-2026 provides purchasing-power-adjusted comparisons for 30 university cities.
The financial pressure on doctoral students is not merely a comfort issue. Research on graduate student mental health consistently links financial insecurity to heightened anxiety and attrition risk — a feedback loop that funding bodies are beginning to acknowledge through the kind of above-inflation increases UKRI and Canada have implemented since 2024.
Trends: Are Stipends Keeping Pace with Inflation?
The most notable recent policy movements are:
- UK: UKRI increased its minimum stipend by 8% for 2025–26, the largest real-terms increase in over two decades, then by a further 4.9% for 2026–27 — maintaining above-inflation growth for two consecutive years.
- Canada: The federal government raised all tri-agency doctoral scholarships to CA$40,000 in September 2024, reversing years of stagnation that had eroded the relative value of the awards.
- Australia: RTP base rates have risen year-on-year as the government indexes them, though the trajectory varies by university. The government has faced public pressure from the Fore Australia campaign to substantially increase the base rate.
- United States: The NSF GRFP has held its stipend at $37,000 since FY2023; there is no announced increase for 2026. Individual universities have raised assistantship floors (Cornell raised its minimum by 8% for 2023–24, per Cornell Graduate School data), but federal fellowship rates have stagnated in nominal terms.
- Germany: TV-L collective agreements are renegotiated periodically; the 2023 round delivered increases, but doctoral salaries continue to be set at 50–65% FTE, limiting absolute take-home pay.
The net picture is one of uneven progress: some jurisdictions have made meaningful real-terms gains while others have allowed doctoral compensation to drift below inflation. For students planning multi-year programmes, understanding how long a PhD takes in their country matters as much as the headline stipend — four years at £20,780 is a very different financial commitment than four years at CA$40,000.
Prospective doctoral students can supplement the national data in this article with targeted searches — PhD scholarship databases often list institutional stipend rates alongside eligibility criteria, allowing direct comparisons across programmes in the same field. Platforms like Tesify also help doctoral researchers structure their thesis chapters efficiently, which matters most during the final stipend-supported stretch of a programme.
Frequently Asked Questions
What is the average PhD stipend in the US in 2025–26?
The average PhD stipend across US programmes is approximately $30,904 per year, based on the PhD Stipend Survey (phdstipends.com). The NSF GRFP flagship fellowship pays $37,000 in stipend plus a $16,000 Cost of Education allowance. STEM assistantships at research universities typically fall between $28,000 and $45,000; humanities programmes range from $20,000 to $35,000.
What is the UKRI PhD stipend for 2026–27?
From 1 October 2026, the UKRI minimum doctoral stipend rises to £21,805 per year outside London and £23,805 in London — a 4.9% increase over the 2025–26 rates of £20,780 and £22,780 respectively, as confirmed by UKRI and reported by Research Professional News in February 2026.
Do PhD students in Germany earn a salary or a stipend?
Both models exist. Most German PhD positions are employment contracts at TV-L E13 pay group, 50–65% FTE, yielding approximately €1,370–€1,800 net per month (2026 rates). A minority of doctoral candidates hold stipends from DAAD (~€1,200/month, tax-free) or DFG Research Training Groups. Employment contracts accrue social insurance entitlements; stipends do not.
Are PhD stipends taxable?
Tax treatment differs by country. In Australia, RTP stipends for full-time domestic PhD students are tax-exempt under ATO rulings. In the UK, UKRI stipends are also tax-free for full-time research students. In the US, stipends are generally taxable as ordinary income unless covered by a scholarship exclusion; the $16,000 NSF GRFP Cost of Education allowance is non-taxable when applied to tuition. In Germany, TV-L E13 salaries are subject to standard income tax and social insurance deductions.
What country offers the highest PhD stipend in real terms?
On a purchasing-power-adjusted basis, Switzerland (not covered in this article’s main comparison, but frequently cited) and Scandinavia typically rank highest globally, with doctoral salaries of CHF 50,000–55,000 and NOK/SEK equivalents well above living wage. Among the countries compared here, Canada’s CA$40,000 and Australia’s AU$37,000+ rates provide strong purchasing power relative to cost of living outside major cities, while the US NSF GRFP at $37,000 in expensive metros often falls short of local living wages.
Can I negotiate my PhD stipend?
In most countries, stipends attached to government-funded fellowships (NSF GRFP, UKRI, CGRS-D, RTP) are set by the funding body and cannot be individually negotiated. However, some universities top up fellowship stipends from their own funds. Institutional teaching assistantships and research assistantships funded from supervisor grants may have more flexibility, particularly in the US and Canada. Contacting the graduate administrator directly — and knowing the market rate for your field — is the starting point.
