How it works
Customer payment = Product price + buyer-paid shipping
Fees = Price × selling fee rate + payment × payment fee rate
Estimated earnings = Payment − fees − cost − shipping expense − packaging − ads
Returns, discounts, fixed costs, taxes, payment-method differences, platform rounding and recognition timing are excluded. Estimated earnings are NOT after-tax net profit.

How to use this profit margin calculator
Enter product price, cost, shipping, packaging and ads to estimate fees, settlement and earnings per sale. Compare multiple products and estimated sales quantities on one page.
How are break-even and target margin prices calculated?
Earnings equal customer payment minus estimated fees and direct costs. Enter a target profit margin to estimate the break-even selling price and the price needed for that margin.
Does it match actual platform settlements?
No. Default fee rates are examples. Actual rates, returns, taxes and fixed costs can differ. Values are in the chosen currency. Country-specific fees and taxes are not applied automatically.
