Profit Margin Calculator

See how much of your revenue remains after the costs you include.

Positive revenue for one item or a consistent period.

Costs for the same item or period; zero is allowed.

Use up to two decimal places without commas or currency symbols. USD inputs are limited to $1 billion.

Formula

Profit = revenue − cost. Margin = profit ÷ revenue × 100. Markup = profit ÷ cost × 100.

Worked example

For an illustrative $80 revenue and $52 cost, profit is $28, margin is 35%, and markup is approximately 53.85%.

What to include

Use revenue and costs for the same item or period. This is not automatically gross or net profit: that depends on which costs you enter. No platform fees, taxes, or overhead are added automatically.

Zero costs and losses

Revenue must be positive. Zero cost gives 100% margin and undefined markup. Cost above revenue produces a loss and negative margin. Money is handled in cents; percentages display up to two decimals.
