Profit margin formulas

Gross margin = (revenue - cost of goods) / revenue x 100; net margin = (revenue - cost of goods - expenses) / revenue x 100; markup = (revenue - cost of goods) / cost of goods x 100

Gross margin looks only at direct costs. Net margin also includes operating expenses.

  1. Enter total revenue for the sale, product, job, or period.
  2. Enter cost of goods or direct delivery cost.

Common questions

What is the difference between profit margin and markup?

Profit margin compares profit to selling price. Markup compares profit to cost. The same sale can have a 40% margin and a 66.7% markup.

How do I calculate net profit margin?

Subtract cost of goods and operating expenses from revenue, divide by revenue, then multiply by 100.

Should I use gross margin or net margin?

Use gross margin to understand direct product or delivery profitability. Use net margin when operating expenses matter to the decision.
