How can I determine whether Carnegie Mellon or UC San Diego would be more affordable for me?

For a California resident, UC San Diego will often be the lower-cost option, especially when California and UC need-based aid applies, but the real answer is the net price shown in your two official aid offers. UCSD charges you the in-state tuition rate, while Carnegie Mellon is private and has the same published tuition for in-state and out-of-state students. Run each school’s current net price calculator, then compare it with your actual award letters once available.

At UCSD, look specifically for UC grants, the Cal Grant, the Middle Class Scholarship, and any campus scholarship funding. These programs can substantially reduce eligible Californians’ costs, and UCSD’s resident tuition advantage remains important even before aid. Confirm whether your award assumes that you will live on campus, off campus, or at home, since UCSD’s housing and meal costs can change the total considerably.

For Carnegie Mellon, separate institutional grants and outside scholarships from loans and work-study. A Carnegie Mellon grant lowers the bill directly; a federal loan must be repaid, and work-study is money you earn through a job rather than an upfront tuition reduction. Carnegie Mellon may be competitive if its need-based grant is large enough to offset the difference between its private tuition and UCSD’s resident rate.

Make a four-year comparison, not just a first-year one. For each college, add billed costs such as tuition, fees, housing, and meals; then add realistic estimates for books, transportation, personal expenses, and travel home. Subtract only grants and scholarships. Ask each financial-aid office whether institutional grants are renewable, what academic or financial conditions apply, and how aid could change if your family’s income changes. The lower remaining amount, after excluding loans and work-study, is the clearest measure of what your family would actually need to pay.
