How it works
Enter the cost and the selling price and the tool returns the profit (price minus cost), the profit margin (profit as a percentage of the price), and the markup (profit as a percentage of the cost). Margin and markup are often confused but measure different bases, so both are shown. A reverse mode finds the selling price needed to hit a target margin from a given cost. Currency formatting is configurable and all math runs locally.
margin % = (price − cost) / price × 100
markup % = (price − cost) / cost × 100
Common use cases
- Pricing a product to hit a target profit margin.
- Comparing margin and markup on a sale.
- Checking the profit on a cost-plus quote.
Frequently asked questions
What is the difference between margin and markup?
Both measure profit, but against different bases. Margin is profit divided by the selling price; markup is profit divided by the cost. A 50% markup is only a 33% margin, so mixing them up distorts pricing.
Can it find the price for a target margin?
Yes. Enter your cost and a desired margin percentage and the reverse mode computes the selling price that achieves it.
