Markup vs. Margin: They're Not the Same

People mix these up constantly. Markup is profit as a percentage of cost. Margin is profit as a percentage of selling price. Same dollar amount of profit, different denominators, completely different numbers.

Buy a shirt for $20, sell it for $30. Your profit is $10. Markup = $10 / $20 = 50%. Margin = $10 / $30 = 33.3%. Same shirt, same $10 profit.

The Formula

Selling Price = Cost × (1 + Markup% ÷ 100)
Profit = Selling Price − Cost
Margin% = Profit ÷ Selling Price × 100
