Amounts are rounded for display; calculations use the full values. Round a target price up to your currency’s smallest unit before selling.

Behind the numbers

Behind the numbers

Gross profit = selling price − cost

Margin (%) = gross profit ÷ selling price × 100

Markup (%) = gross profit ÷ cost × 100

Rates in formulas are decimals: 30% is calculated as 0.30.

A practical example

A $100 sale isn’t $100 in profit

An online retailer sells an item for $100 that costs $60. Gross profit is $40, margin is 40%, and markup is 66.67%. A 40% markup would produce a different price: $84.

What this includes

Common questions

Why aren’t margin and markup the same?

They use different denominators. Margin measures profit as a share of revenue; markup measures the increase over cost. Use margin when comparing the share of revenue retained.

Can my profit margin be negative?

Yes. If an item costs $75 and sells for $50, it loses $25 and has a −50% margin. This is a real loss, not an invalid calculation.
