The calculator

Enter revenue, labour, materials, equipment, subcontractors and other direct costs for the same scope. Their difference is direct margin; the percentage uses revenue as its denominator. The result does not automatically include company overheads and is not net profit or cash receipts. Without revenue, the percentage cannot be calculated.

Fields start from a realistic example — replace them with your own numbers.
