How we compute Degree value-add & ROI. Investment basis = average net price × 4 years + median debt (net price preferred; published sticker cost used as a fallback). Earnings premium = median earnings 10 years after entry minus the $46,700 typical earnings of a worker with only a high-school diploma (BLS Current Population Survey, median annual earnings for workers with a high-school diploma and no college (~$899/week, 2023)). Degree value-add = premium × 10 years minus total cost, the net return of the degree itself over a high-school career (it can be negative). ROI multiple = 10-year premium ÷ cost. Payback = cost ÷ annual premium. Ranked by value-add among the 918 four-year colleges in this snapshot that report both earnings and cost; 226 of them do not pay back at ten years. Missing values are excluded, never estimated.
