The product margin calculator shows you the difference between what you pay for a product and what you sell it for — as both a margin percentage and a markup percentage. Many e-commerce sellers confuse margin and markup, but the difference matters: a 50% markup on a $20 item means selling at $30 (33% margin), not 50% margin. This tool calculates both, plus your break-even volume if you enter your fixed costs.
How to calculate product margin
Gross profit per unit = Selling price - Cost Margin % = Profit ÷ Selling price × 100 Markup % = Profit ÷ Cost × 100 Break-even units = Fixed costs ÷ Profit per unit
