Public vs Private College: Cost, Salary, and ROI

Using typical inputs (public $27k/yr, private $58k/yr, $15k room and board, $5k public and $15k private scholarships, $55k and $60k starting salaries), the public four-year cost is about $148,000 versus about $244,000 for private. Private's higher starting salary narrows the gap, but on a five-year income-versus-cost basis public still shows a stronger return. Private can be worth it when generous aid drops its net price near public's, or when a specific program meaningfully lifts earnings. Always compare the net price after scholarships, not the sticker.
