Markup vs margin: what's the difference?

They sound interchangeable, but they're measured against different numbers — and that gap is where contractors lose money.

Markup is your profit as a percentage of what the job cost you. Margin is your profit as a percentage of what you charged. So a 50% markup isn't a 50% margin — it's only 33%.

If you "add 30%" to your costs thinking you're keeping 30%, you're actually keeping about 23%. On a $10,000 job that's roughly $700 you assumed was profit but wasn't.

If your markup is… …your margin is
10%9.1%
25%20.0%
50%33.3%
100%50.0%

Rule of thumb: decide the margin you need to stay profitable, then use the calculator above to find the markup that gets you there.
