Construction Profit Margin Calculator
Enter the contract price and your job costs to see profit and margin. On a $250,000 job with the example costs below, net profit is $35,000.00.
How the construction profit margin calculator works
Enter the contract price, then the direct costs of the job: materials, labor and subcontractors. Add your overhead as a percent of the contract price. The calculator returns gross profit, net profit, both margins and two markup figures so you can see what the job really earns.
Gross profit is the price minus direct job costs. Net profit takes overhead out of that as well. Overhead covers costs that are not tied to one job, such as the office, insurance, vehicles, software and owner salary. If you do not know your overhead rate, the contractor overhead calculator can work it out.
The formulas
Example: With the default inputs the gross profit is $60,000.00, a gross margin of 24%. Overhead of $25,000.00 brings net profit to $35,000.00, a net margin of 14%. Total cost is $215,000.00. The markup on direct cost is 31.58% and the markup on total cost is 16.28%. These figures are an illustration, not a benchmark for your trade.
Margin versus markup
Margin is measured against the selling price. Markup is measured against cost. A 24 percent margin is not a 24 percent markup, and mixing them up is a common way to underprice a bid. To go from a target margin to a price, divide cost by one minus the margin. Our margin calculator handles that conversion directly.
Limits
The tool treats overhead as a flat share of price and ignores taxes, financing, warranty reserves, change orders and retainage. Use real job costs, including payroll taxes and insurance in labor. This is a planning estimate and not financial or tax advice. To build a full bid from quantities, see the contractor bid calculator.
Where overhead comes from
Overhead is the cost of running the business that you cannot charge to one job. Typical items are office rent, insurance, vehicles, tools, software, advertising, administrative pay and the owner’s salary. Add them up for a year and divide by annual revenue to get an overhead percent. If you enter an overhead percent that is too low, the net profit and net margin will look better than they really are.
Using the results to bid
Work backwards from the margin you need. Enter your estimated costs, then adjust the contract price until the net margin reaches your target. Compare the gross margin across jobs to see which types of work pay best, and watch the net margin to see whether overhead is eating the gain. A job with a good gross margin can still lose money if overhead is high.
Remember that estimates change. Material prices move, labor takes longer than planned and change orders add cost. Many contractors leave room for contingency in the price, which is not included in this calculator. Re-run the numbers when actual costs come in, and use the totals to tighten your next estimate.

Frequently asked questions
What is a good profit margin in construction?
It varies by trade, job size and market. Compare your own results across jobs rather than relying on one number.
What is the difference between gross and net profit?
Gross profit is price minus direct job costs. Net profit also subtracts overhead. The default example shows $60,000.00 gross and $35,000.00 net.
Is margin the same as markup?
No. Margin divides profit by price, and markup divides profit by cost. The default gross margin is 24%, while the markup on direct cost is 31.58%.
How is overhead handled?
It is entered as a percent of contract price and subtracted from gross profit.
