# Markup & Margin Calculator

> Convert between markup and margin — they are not the same number, and confusing them costs money.

Markup is profit divided by cost; margin is profit divided by selling price. A 50% markup is only a 33% margin, which is why the two are so often confused and why pricing set against the wrong one falls short. Enter any two of cost, price, markup or margin and get the rest.

## FAQ

### Why does a 50% markup give only a 33% margin?

Because the denominators differ. Cost 100, markup 50% gives a price of 150 and profit of 50. Divided by cost that is 50%; divided by price it is 33.3%. Setting a 50% markup when you needed a 50% margin leaves you a third short.
