How can I compare the true cost of attending USC versus WashU?

The biggest practical tradeoff is that USC’s Los Angeles location can make housing, food, local transportation, and travel materially more expensive, while WashU’s St. Louis setting often has a lower day-to-day cost of living. But the school with the lower posted cost is not automatically cheaper: base the decision on each college’s official first-year financial-aid offer and the amount your family would actually need to pay or borrow. Compare both offers side by side using the same categories, not just the “scholarship” line.

Start with each school’s billed charges: tuition, mandatory fees, housing, and meal plan. Then subtract only gift aid, such as university grants, need-based scholarships, and outside scholarships that reduce your bill. Keep loans, parent borrowing, and work-study separate; they can make an offer look larger, but they are not discounts in the same way grants are.

Next, estimate indirect costs for each campus: books and supplies, health insurance if you will not waive the school plan, personal expenses, travel home, and transportation. USC students should pay particular attention to Los Angeles transportation and what happens to housing costs after any guaranteed on-campus housing period. At WashU, check the expected cost of living off campus in later years as well, rather than assuming the first-year housing price will remain your long-term cost.

Also read the renewal terms for every award. Confirm whether a scholarship is guaranteed for four years, what GPA or enrollment requirements apply, whether need-based aid is likely to change if family income or assets change, and whether tuition increases are covered by fixed-dollar awards. If either offer seems to overlook a major change in your family’s finances, submit a documented aid appeal before committing.

The most useful verdict is the four-year net price: add your expected annual out-of-pocket cost, realistic indirect expenses, and any borrowing at USC and WashU, then compare the totals. Choose USC only if its aid package closes enough of the Los Angeles cost gap to make the four-year difference manageable; otherwise, WashU may be the more affordable option even if the initial aid letters appear close.
