About the profit & margin calculator
Calculate revenue, costs, gross profit, profit margin, markup, and return on investment. This tool is designed to provide a quick estimate with clear, easy-to-understand results. It runs in your browser and does not require you to create an account.
How the calculation works
Profit = selling price − total cost. Margin = profit ÷ selling price × 100.
Example
Selling an item for 50 that costs 30 produces a profit of 20 and a 40% margin.
