Enter the real cost of the job and the gross margin you want. The calculator shows the quote price, markup percentage, and gross profit so you can stop guessing.
If a job costs $1,000 and you add a 50% markup, the price is $1,500. Your profit is $500, but your margin is only 33.3% because margin is profit divided by the final price.
cost / (1 - margin) margin / (1 - margin) Markup is profit divided by cost. Margin is profit divided by selling price. A 50% markup on a $1,000 job cost creates a $1,500 price and a 33.3% gross margin.
Margin is usually clearer because it tells you what share of the final price remains after job cost. Markup is still useful when crews think in cost-plus terms.
Include materials, subcontractors, labor burden, rentals, permits, disposal, and job-specific overhead. Do not hide real costs outside the calculation.
