Margin and markup calculator

Margin is profit divided by selling price. Markup is profit divided by cost. A 50% markup does not mean a 50% margin.

Change-order margin check

Use the base job above, then add the cost and customer price of proposed extra work.

Enter the full direct cost, including the labor you intend to count. Results exclude overhead, taxes and unentered costs. No measurements, supplier rates or legal terms are inferred. These calculators run in your browser; entered amounts are not submitted.

Keep the calculation with the job

PropertyPromoKit connects reviewed estimates, photos, approved changes and entered job costs. Profit Guard compares your quote-cost budget with actuals in your workspace.
