What is the difference between markup and margin?
Markup is the percentage added to your cost to set a sale price. Margin is the percentage of the final sale price that remains as profit. They are not the same number.

Why 20% markup is not 20% profit
It is the most common financial mistake in the industry. Understanding this difference is the key to stop losing money without realizing it.
Markup
It is the percentage you add to your direct costs to set the sale price. It looks backward, focused on what you already spent.
Markup = (Profit / Cost) × 100
- ✓Easy to calculate mentally.
- ✓Useful for quick quotes.
- ✗Gives a false sense of high profitability.
Real margin
It is the percentage of your total sale price that actually becomes profit. It looks forward—the real money your business keeps.
Margin = (Profit / Sale price) × 100
- ✓Reflects the real health of your business.
- ✓Taxes and fees are calculated on this base.
- ✓This is what investors and banks look at.
The growth trap
Imagine your project costs $1,000. You add 20% markup and charge $1,200. Your profit is $200. But $200 is only 16.6% of the $1,200 you collected. If operating costs, surprises, or taxes (always calculated on the sale price) add up to 18%, you lost money working even though you thought you had 20% profit.
Frequently asked questions about margin and markup
Why does a 20% markup not equal a 20% margin?
Because markup uses cost as the base and margin uses sale price as the base. With a 20% markup, your real margin is lower, so many contractors overestimate profitability.
What margin should I target in construction jobs?
It depends on trade, risk, and overhead, but you should define a target margin and quote from that objective. Use this calculator as a pricing checkpoint before sending estimates.
How do I use this result in my estimate workflow?
Calculate your real margin first, then adjust line-item pricing before sharing the quote. This helps protect profit after taxes, overhead, and unexpected costs.
