Interpretation

How profit margin works

Profit margin shows how much of your selling price is kept as profit after covering cost. It is different from markup.

Profit margin = (profit ÷ selling price) × 100
Markup = (profit ÷ cost price) × 100

For example, if a product costs £40 and sells for £60, profit is £20. The margin is 33.3% because £20 is one third of the selling price. The markup is 50% because £20 is half of the cost price.

Common questions

What is the difference between margin and markup?
Margin is profit as a percentage of selling price. Markup is profit as a percentage of cost. They are not the same.
How do I find selling price from a target margin?
Use: selling price = cost ÷ (1 − target margin as a decimal). For a 30% margin, divide cost by 0.70.
What does break-even mean?
Break-even is the number of units you need to sell so that contribution profit covers your fixed costs.
