Markup vs Margin: Why Contractors Accidentally Lose Money
One of the most dangerous bidding errors in construction estimating is confusing markup with gross margin. If you have $10,000 in job costs and want a 25% profit margin, marking up your cost by 25% gives you $12,500. However, $2,500 on a $12,500 ticket is only a 20% margin—leaving your overhead uncovered.
1. Markup Formula
Markup is how much higher your price is compared to what you paid:
Example: A $100 material cost marked up by 50% sells for $150.
2. Margin Formula
Margin measures what portion of the total contract price you keep:
Example: That same $150 invoice with $50 profit yields a 33.3% margin.
