    How to Use

    1. Enter your unit cost (what you paid for the product) in the Cost field.
    2. Enter your selling price in the Selling Price field.
    3. Read your markup percentage, dollar profit, and equivalent profit margin on the right.
    4. 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.
