Mercari fee calculator (2026)

One 10% fee, and no seller processing fee

On the default sale — $40 item, $5 shipping paid by the buyer, $12 cost, $4 postage, $1 packaging — the buyer pays $45.00. Mercari's fee is $4.50 (10% of the $45 base) and you keep $23.50, which is 52.2% of what the buyer paid.

Selling fee — 10%

Charged on the item price plus the shipping the buyer pays. Selling an item cheaply with expensive shipping does not reduce the fee, because the shipping is in the base. Many guides and calculators still show 12.9% + $0.50 — the old selling-plus-processing model. On this sale that would take $6.31 instead of $4.50, understating your payout by $1.81.

Payment processing — nothing charged to the seller

Since 6 January 2025 the separate 2.9% + $0.50 processing charge is gone from seller payouts in the US; the 10% selling fee is the whole marketplace charge. Buyers pay their own 3.6% Buyer Protection fee on top of the price, so it does not come out of your share. Direct deposit is free; Instant Pay costs about $3 per cash-out, which is a cash-flow cost rather than a per-sale fee.

What is not in the default number

Free shipping offers. If you pay the shipping to attract buyers, put that amount in "postage you pay" — or set the buyer's shipping to 0 and your postage to the label cost, which is what actually happens to your money.

Promoted listings. Mercari's promotion tools raise visibility; treat any spend as a cost of the sale if you use them per item.

Returns and cancellations. A return can cost you the outbound and return postage. If returns are common in your category, add the average loss to "packaging / other".

Break-even and target-margin prices

With these costs the item breaks even at $13.89. To keep 30% of revenue rather than any profit at all, the price needs to be $23.33. Mercari buyers negotiate in messages and through offers, so knowing the floor is the difference between a sale and a donation.
