Core formulas
The formulas to keep straight
Mercari fee base = item price + buyer-paid shippingSeller fee = fee base x 10%Buyer Protection fee = fee base x 3.6%Seller profit = fee base - seller fee - product cost - seller-paid shipping costHow do Mercari fees work in 2026?
Mercari now needs a two-sided fee check. Verified July 4, 2026, Mercari's US fee page says new or updated listings effective January 6, 2025 have a 10% seller fee on item price plus buyer-paid shipping. The same fee page says a 3.6% Buyer Protection fee is charged to the buyer.
That means the seller fee and buyer fee can both be true. The seller does not receive the buyer protection fee, but the buyer still feels it in the price.
Mercari US fee examples, verified July 4, 2026
| Item price | Buyer-paid shipping | Seller fee | Buyer Protection fee | Seller net before costs |
|---|---|---|---|---|
| $20.00 | $5.00 | $2.50 | $0.90 | $22.50 |
| $40.00 | $6.00 | $4.60 | $1.66 | $41.40 |
| $75.00 | $8.00 | $8.30 | $2.99 | $74.70 |
| $100.00 | $10.00 | $11.00 | $3.96 | $99.00 |
Do older Mercari listings use the same fee?
Do not assume every old listing uses the new fee until you check the listing status. Mercari's page says listings created before January 6, 2025 had older buyer-fee treatment until updated, while listings created or updated on or after that date use the 10% seller fee.
For pricing work, use the current rules for any listing you are creating now. If an old listing still sells under older terms, the order report is the source of truth.
- Use 10% seller fee for new listings.
- Use 10% seller fee after updating an older listing.
- Check order details before reconciling an older sale.
Why should sellers care about the buyer fee?
The buyer fee does not come out of the seller payout, but it can make the listing look expensive. A $40 item with $6 buyer-paid shipping becomes $47.66 before tax after the 3.6% Buyer Protection fee. That matters when buyers compare the same used item on eBay, Depop, or Facebook Marketplace.
My rule: calculate seller profit first, then look at buyer checkout price. If the buyer price looks high, adjust item price or shipping presentation before assuming the item is overpriced.

Worked examples
Examples you can compare against your own numbers
Example: $40 item with buyer-paid shipping
A seller lists an item for $40 and charges the buyer $6 shipping. The fee base is $46.
| Fee base | $46.00 | $40 item price + $6 buyer-paid shipping. |
|---|---|---|
| Seller fee | $4.60 | $46 x 10%. |
| Buyer Protection fee | $1.66 | $46 x 3.6%, paid by buyer. |
| Seller net before costs | $41.40 | $46 - $4.60. |
Takeaway: The seller sees a $4.60 platform fee, while the buyer sees an extra $1.66 before tax.
