How to use it
- Choose “Cost and markup” to find a price, or “Cost and price” to find the markup.

- Enter the markup percentage, or the selling price.
- Read the price or the markup, the profit, and the margin that goes with it.
Markup is measured against cost
A 50% markup on a cost of 60 is a price of 90: you add half the cost on top. The margin on that same sale is 33.3%, because 30 of profit is a third of the 90 the customer paid. Suppliers and wholesalers usually quote markup; accountants and investors usually mean margin. Being handed one and reporting the other is the most common pricing error there is.
Picking a markup
There is no correct figure. A markup has to cover everything between the cost you typed and the money that reaches you — processing fees, returns, support, the sales that never happen — plus the profit you actually want. Work out the margin you need first, then read off the markup that produces it; that direction is the profit margin calculator.
Questions
How do I calculate markup?
Divide the profit by the cost. A cost of 60 sold at 90 is 30 of profit, and 30 ÷ 60 is a 50% markup.
How do I add a markup to a cost?
Multiply the cost by one plus the markup. A 40% markup on 25 is 25 × 1.4 = 35.
Is a 50% markup the same as a 50% margin?
No. A 50% markup on a cost of 60 gives a price of 90, which is a 33.3% margin. A 50% margin needs a price of 120, which is a 100% markup.
Can markup be more than 100%?
Yes. Markup is measured against cost and has no ceiling: an item that costs 5 and sells for 20 has a 300% markup and a 75% margin.
What is keystone pricing?
Doubling the wholesale cost to set the retail price. That is a 100% markup, which is a 50% margin. It is a convention in some retail, not a rule.
