Every income band — the federal numbers (Public-school prices below reflect what in-state families reported paying; out-of-state families typically pay more.)

Household incomeAvg net price / yr≈ four years*

*Four-year figures grow each year's price by 3.5% — the same method College Compass uses in a family's plan. "Net price" is what families actually paid after grants and scholarships, as reported to the U.S. Department of Education — not a calculator's estimate. Federal reporting groups every income above $110k into one band; families well above it often pay closer to the full cost.
