Estimating the total cost for a four-year undergraduate education at Illinois State University involves combining instructional tuition, mandatory student fees, on-campus housing accommodations, and meal plans. For in-state resident students, the cumulative gross cost over four academic years typically ranges between 100,000 and 115,000 dollars before accounting for financial aid, institutional scholarships, or grants. Out-of-state students face significantly higher total sticker prices, though a vast majority of students receive financial assistance packages that lower net out-of-pocket expenses considerably.
