How it works

What the calculator is doing

Enter the revenue or selling price and the total cost tied to the work, product, or project you want to evaluate.

The calculator subtracts cost from revenue to find the profit amount.

It then divides profit by revenue to estimate the profit margin percentage, which helps when you want to compare results across different-sized deals.

Understanding your result

Profit tells you how many dollars are left. Margin tells you what share of revenue those dollars represent. Seeing both together makes it easier to compare small, large, and repeatable work without guessing which result is healthier.

Ways people use this tool

Example scenarios help turn a quick estimate into a more useful comparison or planning step.

Check margin on a quoted project

Enter expected revenue and total cost before finalizing a quote so you can see whether the job still leaves enough room.

Compare two pricing options

Use the same cost with two different revenue figures to see how a higher price changes both profit and margin.

Review a completed job

Enter the actual numbers after the work is done to see whether the project performed as expected.

FAQ

Common questions

What is the difference between profit and margin?

Profit is the dollar amount left after costs. Margin is that profit expressed as a percentage of revenue, which makes comparisons easier.

Can the margin be negative?

Yes. If total cost is higher than revenue, the calculator will show a loss and the margin percentage will be negative.

Should overhead be included in total cost?

If the decision depends on real profitability, include any overhead or operating cost you want the estimate to reflect.
