Markup vs. Margin Calculator for Contractors

Enter a job cost and a target. The calculator converts markup and margin correctly and shows what a discount does to margin dollars. Figures are not a recommended price and not a promise about your profit.

Cost does not fall when the price is discounted. Always look at dollars remaining, not only the new percentage. Replace the $10,000 starter figure with your own complete cost - labor burden, materials, other direct costs, and a fair share of overhead.

Why contractors mix these up

Markup is the percentage you add on top of cost. Margin is the percentage of the selling price that remains after cost. A 25% markup on a US$10,000 cost is a US$12,500 price and a 20% margin - not 25%. To hold a 25% margin on that same cost, the price is US$13,333.33. That gap is about US$833 in the bid. These figures are a teaching example only.
