# Gross Margin Calculator

Calculate gross margin and markup from cost and selling price. Understand the difference between margin (% of revenue) and markup (% of cost). Free, no ads.

## Quick answer

Gross Margin = (Revenue − Cost) ÷ Revenue. Markup = (Revenue − Cost) ÷ Cost. Example: Cost $100, Price $150 → Gross Margin = 33.3%, Markup = 50%. These terms are often confused — retailers use markup; financial analysts use margin.
