Margin Calculator

The Margin Calculator shows you exactly how much profit you're making on every sale. It's free to use and requires no sign-up, so retailers, freelancers, and online sellers can check pricing on the fly. It's especially useful when you're setting prices for a new product and need to know if your margin actually covers your costs.

How does Margin Calculator work?

Margin measures how much of your selling price is actual profit after covering the cost of the item. The calculation is margin = (selling price − cost) ÷ selling price × 100, which is different from markup, a common point of confusion for new sellers. Entering your cost and price lets you see the percentage instantly, along with the profit amount in currency.

Frequently asked questions

Is Margin Calculator free?

Yes, the Margin Calculator is free with no sign-up needed. You can check margins for as many products or price points as you want at no cost.

Is margin the same as markup?

No, margin and markup are calculated differently even though both describe profit. Margin is profit divided by selling price, while markup is profit divided by cost, so the two percentages are never equal for the same sale.

What margin percentage is considered good?

A healthy margin depends heavily on your industry, since retail, services, and manufacturing all carry very different typical margins. Instead of relying on one universal number, use the calculator to compare your margin against competitors or your own historical pricing.

Can I use this to work backward from a target margin?

The calculator is built around entering cost and price to reveal the margin, so working backward means adjusting your selling price until the displayed margin matches your goal. This trial-and-error approach still takes only seconds since results update instantly.
