About this calculator

Markup ≠ margin. Markup is added to cost (cost × 1.20 = invoice with 20% markup). Margin is what comes out of the invoice (20% markup = 16.7% gross margin). General contractors typically need 20-30% markup just to cover overhead (insurance, vehicles, office) and leave 5-10% net profit. New construction is leaner (15-20%); design-build remodelers run 25-35%. If a quote shows "0% markup" or you're buying at "cost," you're either being misled or the contractor is going broke.

Frequently asked

Markup is added to cost (cost × 1.20 = price). Margin is share of revenue (margin / price). 20% markup = 16.7% margin.
