How construction profit is calculated
Profit is what remains after every cost of delivering the project is subtracted from revenue:
Profit = Revenue − (Material + Labor + Subcontractor + Other Costs)
Profit margin expresses that profit as a percentage of revenue, so you can compare profitability across projects of different sizes:
Profit Margin (%) = (Profit ÷ Revenue) × 100
A fit-out project bills the client $500,000. Materials cost $260,000, labor $110,000, subcontractors $50,000, and other expenses $10,000 — a total cost of $430,000. Profit is $500,000 − $430,000 = $70,000, a 14% profit margin.
Frequently asked questions
What is a good profit margin in construction?
Most general contractors target 8–15% net profit margin, though it varies by project type, region, and risk. Specialty and design-build contractors often target higher margins to cover added risk and design overhead.
Is profit margin the same as markup?
No. Markup is added to cost to set your price, while margin is profit as a percentage of revenue. The same dollar amount of profit produces a different markup % and margin % — see our guide on markup vs. margin.
Should overhead be included as a cost?
Yes. Company overhead (office, admin staff, insurance, equipment depreciation) should be allocated to each project, either as a percentage of cost or a fixed amount, before calculating true profit.
