Margin Calculator
Calculate profit margin, markup percentage, and revenue from cost and selling price.
Margin vs. Markup Explained
Profit margin and markup are both measures of profitability, but they use different bases. Margin is calculated as a percentage of the selling price, while markup is calculated as a percentage of the cost. This distinction matters because a 50% markup results in only a 33.3% margin.
Understanding the difference is critical for pricing strategy. If you set prices based on a target margin (common in retail and e-commerce), you need to convert that to the equivalent markup on your costs. Our calculator shows both values simultaneously so you can price with confidence.
