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 $43,393 sticker price. All figures are the full cost of attendance — housing, food, and books included, not just tuition.
| Household income | Est. net price / year |
|---|---|
| Under $30k | $5,098 |
| $30k–$48k | $6,241 |
| $48k–$75k | $9,438 |
| $75k–$110k | $18,177 |
| Over $110k | $22,742 |
Sticker cost of attendance: $43,393 (out-of-state) · $24,591 in-state. GPA context: ~3.7 UW avg.
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.
| Household income | 4 yrs, today's prices | 4 yrs with increases |
|---|---|---|
| Under $30k | $20,392 | $21,488 |
| $30k–$48k | $24,964 | $26,305 |
| $48k–$75k | $37,752 | $39,781 |
| $75k–$110k | $72,708 | $76,615 |
| Over $110k | $90,968 | $95,856 |
First-year aid is not guaranteed to repeat — ask Purdue University how grants change after year one. That answer moves these numbers more than anything else on this page.
Applying to a specific major at Purdue University
50% 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 Purdue University's Common Data Set and its admissions page, or ask an admissions officer directly — that question gets answered more often than students expect.
At Purdue University: 741 bachelor's degrees awarded a year · $85,981 median earnings (Computer Science.)
Applicant demand has grown far faster than faculty and seats, so many universities cap CS enrollment, admit to it directly, or require a competitive internal application after enrolling.
Check: Whether the school admits to CS directly, and whether switching into CS later is restricted — the answer changes your real odds more than your test scores do.
At Purdue University: 1,825 bachelor's degrees awarded a year · $71,255 median earnings (Mechanical Engineering.)
Most engineering colleges admit students directly into the college rather than the university at large, and review them against a separate, usually more selective pool.
Check: Whether you apply to the engineering college directly, and what happens if you are not admitted — some schools offer general admission with a later transfer path, others do not.
At Purdue University: 224 bachelor's degrees awarded a year · $41,565 median earnings (Finance and Financial Management Services.)
Many undergraduate business schools admit their own cohort at application time and are more selective than the university overall; others admit only after two years of coursework.
Check: Whether the business school is direct-admit for first-years, and if not, what GPA the internal application actually requires.
Federal data shows no bachelor's completions at Purdue University in nursing, architecture or visual & performing arts, so those are not listed above. Small or new programs can be missing from federal reporting — confirm with the school before ruling one out.
