What is the difference between markup and margin?

SHORT ANSWER

Markup is measured against your cost. Margin is measured against your selling price. The same dollar of profit produces a bigger markup number than margin number.

Buy at $100, sell at $150. You made $50. As a share of the $100 cost that is 50% markup. As a share of the $150 sale it is 33% margin.

Suppliers and pricing talk in markup. Banks, lenders and financial statements talk in margin. You need both, and you need to know which one someone means.

For example

A 100% markup is a 50% margin. A 50% markup is a 33% margin. A 33% markup is a 25% margin.

Why it matters

Operators who quote markup and budget with it as if it were margin consistently overestimate profit — often by a third.

The mistake to avoid

Telling a lender you run 50% margins when you actually run 50% markup.
