Marketplace Fee Calculator
Estimate marketplace fees, net payout, and profit based on your sale price, shipping charged, product cost, and fee rates.
Overview
A marketplace fee calculator helps sellers estimate total fees, net payout, and profit before listing or repricing a product. Enter your sale price, shipping charged to the buyer, product cost, percentage fees, and any fixed fee to see how much you may keep from each sale.
How it works
The calculator first adds the sale price and shipping charged to find the gross order value. It then applies the marketplace fee rate and payment processing rate to that amount, adds any fixed fee, and subtracts the total fees from the order value to estimate net payout. Finally, it subtracts your product cost to estimate profit and expresses that profit as a percentage of the order value.

Frequently asked questions
What does this marketplace fee calculator estimate?
It estimates total selling fees, your net payout after fees, and your profit based on the values you enter.
Should I include shipping charged to the buyer?
Yes. Many marketplaces charge fees on the full amount paid by the buyer, including shipping, so this calculator includes it in the order value.
Does this calculator include my product cost?
Yes. Your entered product cost is subtracted after fees to estimate profit.
Can I use this for any online marketplace?
Yes, as long as you know the marketplace percentage fee, payment processing fee, and any fixed fee per order.
Why might my actual payout be different?
Actual payouts can differ because of taxes, refunds, promotions, category-specific fees, shipping-label charges, reserves, or fee minimums and caps.
What is the difference between net payout and profit?
Net payout is what remains after marketplace fees. Profit goes one step further by also subtracting your product cost.
