- Enter your selling price in the Selling Price field.
- Read your markup percentage, dollar profit, and equivalent profit margin on the right.
- Want to convert a margin target into a markup target? Use our Profit Margin Calculator — the two metrics move in opposite directions on the same trade.
Formula Explained
Markup (%) = ((Selling Price − Cost) / Cost) × 100
- Selling Price
- = Final price charged to the customer
- Cost
- = Your unit cost — what you paid the supplier or to produce the item
Worked example: Cost $60, selling price $100. Markup = ($100 − $60) / $60 = 0.6667 = 66.67%. That same trade is a 40% margin.
