Seller Fee and Margin Calculator
Estimate seller profit and margin from your own selling price, product cost, shipping and fee assumptions. Enter your own assumptions. The calculator does not claim live provider pricing or retailer inventory.
Net profit = sale price − product cost − shipping − other costs − (sale price × fee percent / 100 + fixed fee). Net margin = net profit / sale price × 100.

Amounts use the same currency within each calculation. No retailer prices, stock, fees, tax rates or compatibility statements are fetched or guaranteed.
