02

Subtract every variable cost

Products, fulfilment, packaging, ads, transaction fees and estimated refund loss.

03

Get contribution profit, margin, break-even item price and target-margin price.

Important: A 25% profit margin isn't the same as a 25% markup. This calculator uses margin = (revenue − variable costs) / revenue. Its break-even and target prices assume the per-order costs you entered stay fixed while the item price changes; real fees and ad costs can vary. Enter selling price excluding collected sales tax, or account for taxes in your costs.
