Marketplace Profit Calculator
Break down referral, payment, fulfilment and ad fees per marketplace, then get net profit, margin and your break-even price.
Variable fees are charged on the selling price; fixed fees (fulfilment, storage, payment fixed fee) are not. ROI uses cost plus shipping as the denominator, margin uses the price.
Amazon referral fees were read from the official pricing page on 2026-09-18, including the tiered categories. Other marketplaces are example values until they are verified the same way.
Estimates only. Marketplaces change fees and your account may have different rates or additional charges — always reconcile against your own statements.
The whole calculation runs in your browser; nothing is sent to us.
