How can I accurately compare the cost of attendance at UIUC and the University of Michigan?

The meaningful comparison is each school’s estimated net price: total annual cost of attendance minus grants and scholarships, not loans or work-study. Run the official net price calculator for UIUC and Michigan using the same parent income, assets, household size, and number of siblings in college, then save both results.

Use the same housing assumption at both schools. Compare a residence hall and meal plan with a similar lifestyle at each campus, then add realistic personal expenses such as books, laundry, winter clothing, health insurance if you will not remain on a family plan, and spending money. Do not assume the schools’ personal-expense allowances will match your own habits.

Travel is likely a real difference: Urbana-Champaign is close enough for many Illinois students to make lower-cost trips home, whereas Ann Arbor may require more gas, train, bus, or flight spending depending on where you live. Estimate round-trip costs for the number of visits you actually expect to make each year, including breaks.

Finally, compare four-year affordability rather than only first-year offers. List renewable scholarships separately, note their GPA or enrollment requirements, and distinguish grants from federal loans, parent loans, and work-study. Revisit the calculations once you have actual aid offers.
