Mercari fee calculator FAQs

How much does Mercari charge in fees?
For current US listings, Mercari charges sellers 10% of the item price plus buyer-paid shipping, with no separate payment-processing fee. A $30 item plus $5 buyer shipping has a $3.50 seller fee. The 3.6% Buyer Protection fee is paid by the buyer, not deducted as a seller fee in this calculator.
Did Mercari's fees change recently?
The current US schedule took effect January 6, 2025: sellers pay 10% of item price plus buyer-paid shipping, and no separate payment-processing fee applies to new or updated listings. This schedule was checked on October 3, 2026 against the official Help Center.
How does Mercari shipping protection affect ROI?
Eligible Mercari prepaid labels provide shipping protection up to $200 for standard, economy, and Media Mail shipments, or up to $20 for First-Class Envelopes, subject to Mercari's conditions. Your own label does not qualify for Mercari Shipping Protection. Enter any carrier insurance you pay for under Other costs; this calculator does not model shipment-loss probabilities or insurance payouts.
Which optional costs are excluded from the seller fee?
The 10% estimate covers the standard seller fee. Withdrawal fees, cancellation charges, seller-funded shipping, packing, and any paid optional services are separate costs. Enter shipping costs you cover under Actual shipping cost and other expenses under Other costs. The estimate does not predict whether an optional service will pay for itself.
What about Mercari Local versus shipped?
This calculator only models shipped sales, so it doesn't estimate Mercari Local fees. Check Mercari's Help Center for those. For shipped sales, the current standard US seller schedule doesn't add a separate payment-processing fee. This calculator estimates 10% of the item price and entered buyer-paid shipping. Any optional delivery, shipping-label, cancellation, or withdrawal costs need to be accounted for separately.
Are Mercari cash-out fees real?
Mercari's fee schedule, checked October 3, 2026, lists no fee for a completed direct deposit, a $2 charge for a failed direct deposit, and a $3 flat fee for each Instant Pay cash-out. These withdrawal fees are separate from the 10% seller fee and are not deducted automatically by this calculator. Include any withdrawal cost allocated to this item under Other costs.
