What is profit margin?
Profit margin is the share of revenue left over after covering the cost of goods sold (COGS). It is the most common measure of a business's profitability per unit of revenue.
Profit = Revenue − Cost Margin = Profit ÷ Revenue × 100 Markup = Profit ÷ Cost × 100
Worked example
You buy a product for 100 and sell it for
150:
Profit = 150 − 100 = 50 Margin = 50 ÷ 150 × 100 = 33.33% Markup = 50 ÷ 100 × 100 = 50.00%
Margin vs. Markup
Margin is profit as a percentage of revenue; markup is profit as a percentage of cost. A 50% markup is only a 33.33% margin — they are not the same number.
