What it may cost by family income
Estimated average net price — what families actually pay after grants and scholarships — by annual household income. Net price matters far more than the $88,488 sticker price. All figures are the full cost of attendance — housing, food, and books included, not just tuition.

|---|---|
| Under $30k | $1,716 |
| $30k–$48k | $1,928 |
| $48k–$75k | $5,578 |

Sticker cost of attendance: $88,488. GPA context: ~4.0 weighted; most top 10%.
What the whole degree costs
Every cost figure above is one year. A bachelor's degree is four — sometimes five. Today's-prices makes no assumptions; the second column assumes prices rise ~3.5% a year, in line with recent averages.

Applying to a specific major at Washington University in St. Louis
12% is the acceptance rate for the whole university — not for every major. For the programs below, admission is usually decided separately and is harder than that number suggests. Almost no university publishes a by-major admission rate, and neither does the federal government, so we do not show one: any site that does is estimating.
To find the real figure for your major, check Washington University in St. Louis's Common Data Set and its admissions page, or ask an admissions officer directly — that question gets answered more often than students expect.
