OSU cost of attendance at a glance (2024-25)
| Figure | Ohio State (Columbus) | Oklahoma State (Stillwater) | Oregon State (Corvallis) |
|---|---|---|---|
| Cost of attendance, in-state | $31,162 | $28,615 | $34,878 |
| In-state tuition and fees | $13,641 | $10,444 | $15,117 |
| Out-of-state tuition and fees | $42,423 | $25,964 | $40,077 |
| Extra tuition for nonresidents | $28,782 | $15,520 | $24,960 |
| Average net price after grants | $17,269 | $17,058 | $21,504 |
Cost of attendance is the school's full yearly budget for a first-year student: tuition and fees, housing, food, books and other expenses. Net price is what students who got federal aid paid on average after grants and scholarships. At public universities, both figures describe in-state students.
Net price by family income
The average net price changes a lot with family income. These are College Scorecard averages for in-state students who received federal aid:
| Family income | Ohio State | Oklahoma State | Oregon State |
|---|---|---|---|
| $0-$30,000 | $6,061 | $12,518 | $16,485 |
| $30,001-$48,000 | $5,538 | $12,445 | $15,853 |
| $48,001-$75,000 | $9,708 | $13,913 | $16,651 |
| $75,001-$110,000 | $18,203 | $19,296 | $21,090 |
| Over $110,000 | $27,873 | $24,910 | $29,717 |
Ohio State charges the most out-of-state tuition of the three, yet it has the lowest average net price for families earning up to $75,000. Oklahoma State has the lowest cost of attendance and the lowest net price for families earning over $110,000.
Out-of-state students
If you don't live in the school's state, the tuition gap is large. In 2024-25, out-of-state tuition and fees were 3.1 times the in-state rate at Ohio State, 2.5 times at Oklahoma State and 2.7 times at Oregon State. The federal cost of attendance and net price figures above don't cover nonresidents, so use each school's calculator to estimate your own cost. Our guide to in-state vs. out-of-state tuition covers regional programs that can lower the nonresident rate, such as the Western Undergraduate Exchange, which covers Oregon, and the Midwest Student Exchange Program, which covers Ohio. Each university decides whether it takes part, so ask its admissions office.
