How to calculate profit margin

Working out your margin by hand is easy to fumble, especially when markup and margin get mixed up. This tool does it for you in one step: type in the cost and the price, and your results appear immediately.

Behind the scenes it uses the standard formulas:

Profit = selling price − cost
Profit margin % = (profit ÷ selling price) × 100
Markup % = (profit ÷ cost) × 100

So a product that costs $40 and sells for $100 earns $60 profit, a 60% profit margin, and a 150% markup. That’s the kind of clarity a quick profit margin calculator online gives you in seconds.

Margin vs. markup — what’s the difference?

This trips up a lot of business owners, so it’s worth being clear. Margin is your profit as a percentage of the selling price. Markup is your profit as a percentage of the cost. They describe the same dollar of profit from two angles — and confusing them is one of the fastest ways to underprice a product.

That’s exactly why this tool shows both at once. Whether you’re searching for a gross profit margin calculator, a markup calculator, or a clear profit margin vs markup calculator, you get every number side by side, no extra math required.

Why use a free online profit margin calculator?

Pricing decisions deserve more than a rough mental estimate. A dedicated profit margin calculator helps you:

Set prices that actually leave room for profit
Compare products to see which ones earn their place
Sanity-check a supplier quote before you commit
Understand how a discount eats into your margin

And because it’s a profit margin calculator free of any cost or account, you can test different prices as often as you need. It works on desktop or mobile, with results that update the moment you type.

Who it’s for

A clear view of margin matters in almost every business:

Retail & wholesale — work out a healthy retail profit margin or wholesale profit margin before you set your price list
Ecommerce — check the margin on each product before factoring in shipping and platform fees
Freelancers & services — make sure your rates cover costs and still turn a profit
Restaurants & small business — price menu items or services so the numbers add up

However you sell, knowing your margin is the difference between busy and profitable.

Quick profit margin tips

Always price from margin, not markup, if you want a target like “30% margin” to mean what you think it does.
Remember that a high markup doesn’t always mean a high margin — a 100% markup is only a 50% margin.
Factor in all your costs (shipping, fees, packaging) so your gross margin reflects reality.
Revisit your margins whenever supplier costs change; small cost creep can quietly erase your profit.
