Turn a cost into a price. Enter what an item costs you and the markup you want to add, and see the selling price, your profit, and the true margin.
Markup and margin are not the same number — a 50% markup is only a 33% margin. This shows both so you price off margin, which is what actually covers overhead.
Markup is profit as a percentage of cost; margin is profit as a percentage of price. Add 50% markup to a $60 cost and you get a $90 price — but that's a 33% margin, not 50%. Confusing them quietly loses money, so this calculator shows both.
Markup is measured against your cost: markup % = (price − cost) ÷ cost × 100. Margin is measured against your selling price: margin % = (price − cost) ÷ price × 100. They describe the same dollar of profit from two different angles, and confusing them is one of the most common — and most expensive — pricing errors small businesses make.
You buy an item for $50 and sell it for $75. Your profit is $25. As a markup that is $25 ÷ $50 = 50% markup. As a margin it is $25 ÷ $75 = 33% margin. Same $25, two different percentages. A seller who thinks "I want a 50% margin" but actually applies a 50% markup will end up with only a 33% margin and quietly undercharge on every sale.
To turn a markup into a margin: margin = markup ÷ (1 + markup). A 50% markup is 0.5 ÷ 1.5 ≈ 33% margin. To go the other way: markup = margin ÷ (1 − margin). Retailers often use "keystone" pricing — a 100% markup, i.e. doubling cost — which is a 50% margin.
Use it to set a price from a target markup, to reverse-engineer the margin a price actually earns, or to check that a discount still leaves you profitable. Enter your cost and either your price or your target markup, and the calculator solves for the rest.
Multiply your cost by (1 + markup%) to get the price. The difference is your profit. This calculator also converts it to the margin so you can compare prices fairly.
Enough that the resulting margin covers your overhead and leaves profit — many small businesses target a 40–50%+ markup on products, more on specialized work. Check the margin, not just the markup.
