How it works
Methodology & formulas
This calculator is transparent by design. Review the steps and formulas so you can trust the estimate and adjust assumptions when your dashboard differs.
Calculation steps
- 1Add sellingPrice and shippingCharged to get the transaction subtotal.
- 2Apply the editable seller fee rate to that subtotal.
- 3Subtract the seller fee, actual shipping cost, and packaging from seller revenue.
- 4Calculate effective fee rate against the transaction subtotal.
Formulas
- Subtotal = sellingPrice + shippingCharged
- Seller Fee = Subtotal × sellerFeePercent
- Net Before Item = Subtotal − Seller Fee − actualShippingCost − packagingCost
- Effective Fee Rate = Seller Fee ÷ Subtotal × 100
Important assumptions
- Starting U.S. model: Mercari seller fee defaults to 10% of the transaction subtotal, item price plus buyer-paid shipping.
- The Seller fee rate field is editable for legacy listings, non-U.S. sellers, account-specific terms, or future policy changes.
- Buyer protection fees are buyer-side charges and are not counted as seller costs.
- Actual carrier or label cost belongs in Your actual shipping cost when you absorb it or it is withheld from your payout.
- Taxes, promoted listing costs, returns, and Mercari Local charges are outside this estimate unless entered as a cost.
