How it works
Margin is profit as a share of the selling price; markup is profit as a share of cost. A 50% markup is only a 33% margin — mixing them up is a common pricing mistake.
Formula
Margin = (Price − Cost) ÷ Price × 100 Markup = (Price − Cost) ÷ Cost × 100
Example
Cost $40, price $65: profit $25, margin 38.46%, markup 62.5%.
