Profit Margin Calculator

What it does

Calculate profit margin, markup, and gross profit from cost and revenue — or reverse it: input a cost and desired margin, and the tool computes the price you need to charge. Margin is profit as a percent of revenue; markup is profit as a percent of cost. Mixing them up is the number-one pricing mistake, so the tool shows both.

Every computation runs in your browser. Useful for pricing products, evaluating deals, or stress-testing a quote. Follow up with break-even calculator to see how many units you need to sell, or ROI calculator for investment returns.

1. Enter the unit cost.
2. Enter the selling price (or flip to reverse mode).
3. In reverse mode, enter a target margin — the tool returns the required price.
4. Read profit, margin %, and markup % side by side.
