Illinois State University Tuition, Costs & Financial Aid
How much does Illinois State cost after financial aid?
Illinois State University's average net price—what aid recipients pay after grants and scholarships—is $19,398, which sits above the peer median of $15,634 for comparable institutions (same type and size). Aid covers about 43% of the published cost for the average aid recipient, an offset of $14,911 against the sticker total.
Across income bands, the average net price moves from $11,568 for families earning under $30,000 to $12,301 for the $30,001–$48,000 band, $16,348 for $48,001–$75,000, $23,865 for $75,001–$110,000, and $28,224 for families earning over $110,000. The spread between the lowest and highest bands is $16,656, a difference of averages that shows the largest discounts flow to families with lower incomes.
In its 2024-25 Common Data Set, the university reported first-year aid figures for the 2024-25 academic year. Students with need received an average need-based grant of $14,941 and an average total package of $17,600, covering about 70% of need on average.
Of the 2,896 first-year students determined to have need, 352 had their need fully met. The university also awarded merit aid to 1,121 first-year students, averaging $4,917 per recipient.
The published cost of attendance at Illinois State University is $34,309. Azimuth ranks the university #558 for affordability among nonprofit four-year institutions.
After grants and scholarships, the average net price for aid recipients from families earning under $30,000 is $11,568, for those earning $48,001 to $75,000 it is $16,348, and for those earning over $110,000 it is $28,224. The spread between the lowest and highest bands is $16,656.
Aid covers about 43% of the published cost for the average aid recipient, an offset of $14,911. The average net price across all aid recipients is $19,398, which is $3,764 above the $15,634 median for comparable institutions (same type and size).
Borrowers who complete a degree carry a median of $20,482 in federal student loans, $406 above the $20,076 peer median. 91.5% of federal aid recipients take federal loans.
Parents who borrow hold a separate median of $28,767 in Parent PLUS loans. If repaid over ten years, the median federal student debt corresponds to an estimated payment of $233 a month.
Student loans: what does repayment look like?
Borrowing is widespread at Illinois State University: 91.5% of federal aid recipients take federal loans, and the median federal student debt among those who complete a degree is $20,482. That median sits above the peer median of $20,076 at comparable institutions (same type and size) by $406, so the typical federal debt load is in line with peers.
Parent borrowers, a separate population, carry a median Parent PLUS loan of $28,767. In its 2024-25 Common Data Set, the university reported that 59% of its 2,595 bachelor's graduates borrowed from any source, with an average cumulative debt of $26,698 per borrower.
Of those graduates, 57% held federal loans averaging $19,089. Another 14% of the graduates held private loans, which averaged $35,501 per private borrower.
Graduates of Illinois State University earn a median of $62,507 four years after completion, a figure in the 58th percentile among nonprofit four-year institutions. They earn about $369 more than expects for similar students, effectively at the expected level, an outcome in the 56th percentile among nonprofit four-year institutions.
Earnings scenarios derived from the university's program mix suggest a typical earnings level of $62,507, with a downside scenario of $49,209 and an upside scenario of $87,051. The median federal student debt for borrowers who complete a degree is $20,482, which is above the $20,076 median for comparable institutions (same type and size) by $406.
That debt corresponds to an estimated payment of $233 a month if repaid over ten years. Earnings that sit near the model's expectation and a debt level that mirrors the peer median point to a return picture that is steady but not outsized.
Median Parent PLUS borrowing, a separate parent-borrower population, is $28,767. The estimated monthly student payment if repaid over ten years is $233.

Student payment as a share of available income
At median graduate earnings of $62,507, with a $22,590 annual allowance for basic expenses:
7.0% 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.
