Markup Calculator

Markup percentage expresses how much you have added above your cost, measured as a fraction of that cost. The formula is: Markup (%) = (Selling Price − Cost) ÷ Cost × 100. First, profit is determined by subtracting cost from selling price. That profit is then divided by cost — not by selling price — and multiplied by 100. Because the denominator (cost) is smaller than the denominator used for margin (selling price), markup percentages are always higher than margin percentages for the same transaction. The calculator also displays the equivalent profit margin so you can see both perspectives at once. To find a selling price from a target markup, multiply cost by (1 + markup as a decimal): for a 50% markup on $60, the price would be $60 × 1.50 = $90.
