Cost & financial aid brief
Princeton University Tuition, Costs & Financial Aid
How much does Princeton University cost after financial aid?
Aid covers about 93% of the published cost for the average aid recipient, an offset of $77,912 against the sticker price. The average net price across all aid recipients is $6,128, but that single figure masks a steep gradient across income bands.
Families earning under $30,000 see an average net price of $41; the figure moves to $352 for the $30,001–$48,000 band, $1,217 for $48,001–$75,000, $4,478 for $75,001–$110,000, and $36,094 for families earning over $110,000. The spread between the lowest and highest bands is $36,053, a difference of averages that shows the largest discounts are concentrated on families with lower incomes.
The lowest-band net price sits far below the overall average, a pattern that coincides with deep aid targeting at the bottom of the income scale. In its 2025-26 Common Data Set, the university reported required fees of $314 and on-campus food and housing of $22,120 as part of the sticker charges for that year.
Estimated books and supplies ran $1,050, transportation $1,000, and other expenses $3,000.
Princeton University publishes a cost of attendance of $84,040. For aid recipients, the average net price is far lower.
Aid recipients from families earning under $30,000 face an average net price of $41, while those in the $48,001–$75,000 band see an average net price of $1,217. For aid recipients from families earning over $110,000, the average net price is $36,094.
The spread between the lowest and highest bands is $36,053. Azimuth ranks Princeton University #51 for affordability among nonprofit four-year institutions.
Tuition and fees are $62,688 and room and board is $20,250. The average net price for first-time full-time Title IV aid recipients is $6,128, reflecting an average financial aid savings of $77,912 against the published sticker price.
This average net price is below the peer median of $27,371 for comparable institutions (same type and size) by $21,243. The median federal student debt at completion is $10,320.
About 24.1% of federal aid recipients borrow federal loans. This median debt is below the peer median of $24,199 by $13,879.
Median Parent PLUS borrowing stands at $41,000. The estimated monthly payment if repaid over ten years for the median federal debt is $117.
Student loans: what does repayment look like?
Federal borrowing at Princeton University is concentrated among a minority of students: 24.1% of undergraduates take federal loans, and completers who borrow leave with a median federal debt of $10,320. That median is below the $24,199 median at comparable institutions (same type and size) by $13,879.
Parent borrowers, a separate population, carry a median Parent PLUS loan of $41,000. In its 2025-26 Common Data Set, the university reported that 11% of the 1,319 bachelor's graduates in the cohort borrowed from any source.
The average cumulative amount was $21,251 per borrower. Of those graduates, 6% held federal loans averaging $12,304, including 2% who also carried private loans averaging $67,833.
Four years after completing a degree at Princeton University, graduates working and not enrolled earn a median of $108,590, a figure in the 98th percentile among nonprofit four-year institutions. That median runs above the $68,250 median for comparable institutions (same type and size) by $40,340.
Earnings scenarios derived from the university's program mix place the typical outcome at $108,590, with a downside scenario of $57,903 and an upside scenario of $190,062. The median federal debt for borrowers who complete a degree is $10,320, which sits below the $24,199 median at comparable institutions (same type and size).
If repaid over ten years, that debt corresponds to an estimated monthly payment of $117.
Median Parent PLUS borrowing, a separate parent-borrower population, is $41,000. The estimated monthly student payment if repaid over ten years is $117.

Student payment as a share of available income
At median graduate earnings of $108,590, with a $22,590 annual allowance for basic expenses:
1.6% of income above the allowance · Excellent
- Excellent Under 8% · selected scenario
- Good 8–under 12%
- Concerning 12–20%
- High risk Over 20%
How this estimate works
These are modeled earnings scenarios, not observed earnings percentiles. Annual student payments ÷ (earnings − basic-expense allowance). The starting allowance, $22,590, uses the published framework’s 2024 baseline; it is not a current local living-cost estimate. Change it for your budget, including taxes and other obligations. This combines school-level figures for illustration, not a typical individual’s budget or an official school rating. Parent PLUS is separate.
Payment assumptions
Payments are 10-year standard payments on the median balance, before loan fees, used as a yardstick. Rates for newly issued loans may differ, and loans made after July 1, 2026 can repay over a longer term; existing loans keep their original fixed rates.

Net price and borrowing. The 2023–24 income-band averages include living costs and cover eligible first-time, full-time aid recipients; public-school figures reflect in-state tuition. They are not individual aid offers. Peer matching supplies overall net prices, not matched income-band averages. College Scorecard data and documentation.
A personal student-risk assessment also needs your major and borrowing plan; these school-level illustrations do not assign you a personal risk zone.
