Margin & Markup Calculator
Get profit margin and markup from cost and price — or work backward to a target price
Enter your cost and selling price and this calculator shows both your profit margin (as a share of the sale price) and your markup (as a share of cost) at the same time. Flip it around and you can enter just your cost and a target margin to find out what you need to charge. Everything is calculated instantly in your browser and no pricing data is ever sent to a server, so small business owners and online sellers can use it with confidence.

FAQ
- What's the difference between margin and markup?
- Margin is profit as a percentage of the selling price; markup is how much you added on top of cost, as a percentage of cost. A 30% markup on cost works out to only about a 23% margin on the sale price — the two numbers are not the same.
- How do I find the price for a target margin?
- On the "Price from target margin" tab, enter your cost and the margin (%) you want. The tool applies price = cost ÷ (1 − target margin) and instantly returns the required selling price and your expected profit.
- Is my pricing data saved or sent anywhere?
- No. Every calculation runs inside your browser — nothing is transmitted or stored.
