The annual instructional tuition and standard fee costs for an undergraduate student attending Illinois State University vary depending on residency status. For in-state residents, baseline tuition and fees typically range between 15,000 and 17,000 dollars per academic year, whereas out-of-state students face higher price points. When factoring in additional expenses such as residence hall housing, meal plans, and textbooks, the comprehensive yearly gross cost of attendance increases significantly before financial aid is applied.
