What's the difference between margin and markup?
Margin is profit as a percentage of the selling price; markup is profit as a percentage of the cost price — they're different numbers from the same profit figure.
Calculate profit, profit margin, and markup from cost price and selling price, right in your browser.
Enter a cost price and a selling price, and this calculator returns three figures: the raw profit (selling price minus cost price), the profit margin (profit as a percentage of the selling price), and the markup (profit as a percentage of the cost price). Margin and markup are two different percentages of the same profit figure, and mixing them up is a common, genuinely consequential business mistake — a 50% margin and a 50% markup describe very different profitability.
For example, a product costing 100 and selling for 200 has a profit of 100: that's a 50% margin (100 is 50% of the 200 selling price) but a 100% markup (100 is 100% of the 100 cost price). Both numbers are correct, but they answer different questions.

They're different percentages of the same profit — a 50% margin and a 50% markup describe very different profitability, and swapping them can seriously mislead a pricing decision.
The gap between them grows larger as profit becomes a bigger share of the selling price.
Swapping them produces a negative or nonsensical profit figure.
Financial reports often expect margin; supplier or cost conversations often expect markup — check which is expected.
