Does USC change the financial aid for resident versus commuter students? Some schools (e.g. UCs) do, but others (e.g. CSUs) do not. USC’s net price calculator does not ask if the student will be a commuter or resident (unlike the UCs and CSUs).
USC estimates room and board at $12,902. The cost of living at the parents’ house (including food and utilities consumed by the student) and commuting can vary greatly from one family to another.
