How to use this calculator
- Enter the cost and the selling price.
- Press Calculate for the profit, margin and markup.
How it works
Profit = price − cost. Margin = profit ÷ price × 100 (against the sale price). Markup = profit ÷ cost × 100 (against the cost) — the two are different.
Worked example
Cost $80, price $100. Profit $20, margin 20%, markup 25%.
Frequently asked questions
