Mercari’s current US structure is split between seller and buyer: the seller pays a 10% selling fee, while the buyer pays a 3.6% Buyer Protection fee. Mercari does not add a separate seller payment-processing fee.
What the seller pays
The 10% seller fee is calculated on the item price plus buyer-paid shipping. If you offer free shipping, the label or shipping expense is still a cost to subtract from your payout.
| Example | Amount |
|---|---|
| Item price | $50.00 |
| Buyer-paid shipping | $6.99 |
| Seller fee basis | $56.99 |
| 10% seller fee | $5.70 |
If the seller instead pays for shipping, the fee basis in this example is the $50 item price—but the label cost must still be deducted when calculating profit.
What the buyer sees
The buyer pays a 3.6% Buyer Protection fee on the item price and buyer-paid shipping. This is not deducted from the seller payout, but it raises the checkout total and may affect the offer a buyer is willing to make.
Shipping is part of the margin
Mercari’s prepaid label rates can change when carriers and surcharges change. Use the current label shown in the listing flow instead of an old static shipping chart. Compare that cost with shipping independently, then enter the actual amount in the Mercari US fee calculator.
Rates were checked against Mercari’s official fee policy. Always confirm the checkout and payout breakdown for your specific order.
