How to use it
Type the cost price (what you pay) and the selling price (what you charge). The calculator shows your profit, profit margin and markup instantly.
Margin vs markup
- Profit = selling price − cost.
- Margin % = profit ÷ selling price × 100 — profit as a share of the price you charge.
- Markup % = profit ÷ cost × 100 — how much you add on top of cost.
A common mistake is confusing the two: a 50% markup is only a 33.3% margin. Knowing the difference protects your pricing.
Price and sell with confidence
