Markup ↔ margin calculator
Enter your job cost and the margin (or markup) you want. This shows what to charge — and the conversion most contractors get wrong. A 30% markup is only a 23% margin; price from the margin you need to keep.
This calculator is an educational tool. Results are estimates from the numbers you enter — your real costs and obligations vary.

FAQ
Markup is added on top of cost; margin is what's left as a share of the price. A 30% markup equals a 23% margin. Price from margin, then convert to the markup that achieves it.
From margin: price = cost ÷ (1 − margin). From markup: price = cost × (1 + markup). The tool converts between them so you can see both.
