How to use this calculator
- Enter the cost and the markup percentage.
- Press Calculate for the selling price and profit.
How it works
Markup is added to the cost to set the selling price: price = cost × (1 + markup ÷ 100). The profit is the difference.
Markup is measured against cost; margin is measured against the selling price — they are not the same number.
Worked example
$100 cost, 20% markup. Selling price = $120, profit = $20.
Common mistakes
- Confusing markup with margin — a 20% markup is not a 20% profit margin (it's ~16.7%).
- Applying the percentage to the selling price instead of the cost.
