How to calculate a selling price from markup
Markup is how much you add to the cost to set your price. Multiply the cost by the markup percentage to get the profit, then add it to the cost for the selling price. The calculator also shows the resulting profit margin, so you see both views of the same price at once.
The formulas
Price = Cost × (1 + markup% ÷ 100) · Profit = Price − Cost · Margin = Profit ÷ Price × 100
Worked example
Cost $40 with a 150% markup:
- Profit: $40 × 150 ÷ 100 = $60
- Selling price: $100
- Resulting margin: $60 ÷ $100 = 60%
Markup is not margin
They describe the same profit differently: markup is on cost, margin is on price. To convert, margin = markup ÷ (1 + markup). So a 150% markup is a 60% margin, a 100% markup is a 50% margin, and a 50% markup is a 33% margin. Quoting one as the other is a classic pricing error.
Common mistakes to avoid
Confusing markup with margin when setting prices. Marking up only on product cost while ignoring shipping, fees, and returns. Assuming a high markup guarantees profit — check the margin after all costs.
Frequently asked questions
Cost $40 with 150% markup — what's the price?
Profit is $60, so the selling price is $100. That equals a 60% margin.
