Costs & financial aid
Compare the year and population before comparing prices. Published budgets, group averages and your actual aid offer are different.
2026–27 cost of attendance
Published by Washington University in St. Louis$96,994
Published billed charges — not the full cost of attendance
- 2026–27
- Partial costs only
This budget assumes
- Any state of residence
- On campus
- All undergraduates
The school does not publish a complete 2026–27 cost of attendance for this situation. Costs it leaves out are not zero — plan for housing, food, books, travel and personal expenses that are not listed here.
Amounts the school publishes for this situation
Separate published amounts. They do not make up a complete budget, and ICP does not add them together.
- Tuition
- $71,310
- Student activity fee
- $712
- Student health and wellness fee
- $700
- Average housing and food (university meal plan)
- $24,272
- Books and supplies
- $1,412
- Travel (four round trips)
- $1,050
- Miscellaneous
- $2,804
This is the school’s budget before financial aid. It is not a bill, the federal average net price, or your own aid offer.
About this budget
- The school labels these figures 2026–27.
- Source: Undergraduate cost of attendance 2026-27 (WashU Financial Aid Costs) (Washington University in St. Louis Office of Student Financial Services). Researched October 21, 2026; independently audited October 22, 2026.
Research notes: "Total university charges" ($96,994) and "Total other estimated expenses" ($5,266) are published; no grand total. ICP sum = $102,260. Travel assumes four round trips.
Understand the five kinds of college costs
- Tuition & fees
- Instruction and required college fees; living costs are additional unless explicitly included.
- Attendance budget
- College charges plus estimated living, books, travel and other included expenses, before aid.
- Average annual cost after grants & scholarships
- A historical average after federal, state/local and college grant aid for a specified federal-aid population. Outside private scholarships are not automatically deducted; loans and work-study are not discounts.
- Your net cost
- Your entered attendance cost minus selected grants and scholarships. Loans and work-study remain funding sources.
- Borrowing
- Debt to repay, not a discount. Work-study is earned over time, not an upfront bill reduction.
Average annual cost after grants & scholarships
$13,360
2024–25
Includes applicable federal, state/local and college grants and scholarships. First-time, full-time students receiving federal financial aid form the reporting population. The attendance budget includes estimated living expenses. Your actual cost may differ.
About this number: Average annual cost after grants & scholarships
Federal average net price: average attendance cost (tuition, fees, books, supplies and living expenses) minus qualifying federal, state/local and institutional grants and scholarships for this population. Federal aid defines the reporting population, not the only aid deducted; some included students receive federal loans or work-study but no grants. This is a historical average, not a personalized award. Outside private scholarships are not automatically deducted. Loans and work-study are not subtracted. This is not tuition alone, an individual award, a guaranteed price or necessarily a college bill.
