Markup Calculator
Calculate selling price and markup amount from a cost and markup percentage, with the resulting gross margin shown for comparison.
How it works
Markup amount = cost × markup% ÷ 100. Selling price = cost + markup amount. Gross margin% = markup amount ÷ selling price × 100.
Formula / calculation method
markup amount = cost × (markup % ÷ 100)selling price = cost + markup amountmargin % = markup amount ÷ selling price × 100
Worked examples
- A 25% markup on a cost of 100 adds 25 and gives a selling price of 125.
- A 100% markup on 50 adds 50 and gives a selling price of 100, which is a 50% gross margin.
