How we compute this. Payback = total net cost ÷ annual earnings premium, where the premium is median earnings 10 years after entry minus the $48,360 baseline (BLS 2024 median for a high-school-diploma worker 25+). Total net cost = net price × 2 years. We do not discount future dollars. The institution-wide earnings figure blends every major — a specific program's payback can be far better or worse.
