Calculate profit and profit margin from cost and selling price.
How to use Margin
- Enter the values you want to calculate and choose the relevant units or settings.
- The result updates as you type. Adjust the available settings if needed.
- Review the result, then use Copy result or a download link when available.
What to expect
Calculate profit and profit margin from cost and selling price. Profit is selling price minus cost. Margin divides that profit by selling price, so a zero selling price is undefined.
