Mercari charges sellers one fee: 10% of the item price plus any shipping the buyer pays. There is no separate processing fee for sellers.
How Mercari calculates the fee
- 10% selling fee on the item price + buyer-paid shipping (listings created or updated on/after Jan 6, 2025). No separate seller payment-processing fee. Buyers separately pay a 3.6% Buyer Protection fee.
- Mercari's help page defines the fee base as item price plus buyer-paid shipping; sales tax is not part of it.
Example (formula-derived)
$50 item + $7 buyer-paid shipping: 10% x $57 = $5.70 selling fee. Payout $51.30 before your label cost.
Not included
