Adjust figures to match your product and seller account.
1
Original price & order costs
Enter the listed price and costs for one order. The discount is applied before percentage-based fees.
2
Marketplace fees
Enter the percentage fee and any fixed transaction charge that apply to your selling channel.
Sales tax is not treated as seller revenue. Some platforms calculate fees on buyer-paid tax; enter it separately where a tax field is provided. Estimates do not automatically model actual refund adjustments, chargebacks or costs not entered above. Enter a return allowance where relevant and reconcile against your actual seller statements.
Independent educational estimate, not an official marketplace calculator, accounting or tax advice.
