What is Profit Margin?

Profit margin measures how much of your revenue remains as profit after covering costs. It shows how efficiently you turn sales into profit.

Profit Margin Formula

Profit = Revenue − Cost
Gross Margin % = Profit ÷ Revenue × 100
Markup % = Profit ÷ Cost × 100

Margin vs Markup – What's the Difference?

Margin is based on revenue. Markup is based on cost. A 50% markup does not equal a 50% margin.
