Mercari charges one flat 10% — but the base includes the shipping your buyer pays, and the 2.9% + $0.50 processing fee everyone still quotes was eliminated in January 2025. See the fee split on item vs shipping and your true net payout.
Selling Fee = 10% × (Item Price + Buyer-Paid Shipping); Net Profit = (Item + Shipping) − Fee − Item Cost − Label CostMercari's entire seller-side cost is one flat 10% applied to the order amount including buyer-paid shipping. The separate 2.9% + $0.50 payment processing fee was eliminated on January 6, 2025. Your payout is the order total minus the fee minus any label costs deducted for buyer-paid shipping.
| Symbol | Meaning |
|---|---|
| 10% | The only seller fee — no listing, subscription, or processing charges on top |
| Buyer-Paid Shipping | Included in the 10% fee base — the most commonly missed detail |
| Label Cost | Postage deducted from your payout when the buyer pays for an in-app label |
| Instant Pay | Optional $3 flat immediate cash-out — avoidable by using free Direct Deposit |
Our calculations are based on established financial and scientific formulas. The following sources inform the default values and methodology used in this calculator:
Mercari's selling fee is a flat 10% with no fixed per-order charge — but the base is the order amount, and the order amount includes shipping the buyer pays you. The money for the label passes through your settlement on its way to the carrier, and Mercari takes its 10% in transit. Sellers who quote "just 10% of the item price" understate their fee by exactly the shipping share.
| Item price | Buyer shipping | Fee on item | Fee on shipping | Total Mercari fee |
|---|---|---|---|---|
| $30.00 | $0.00 | $3.00 | $0.00 | $3.00 |
| $30.00 | $8.00 | $3.00 | $0.80 | $3.80 |
| $30.00 | $15.00 | $3.00 | $1.50 | $4.50 |
Same item three ways. Every dollar of buyer-paid shipping costs you ten cents of fee on top of the label itself.
Two pricing habits follow. First, charging shipping separately does not dodge the fee — bundling it into the item price puts the same total in the same base. What changes is which number the buyer sees in search: Mercari buyers filter and compare on item price, so a $30 + $8 shipping listing and a $38 free-shipping listing cost the buyer the same but do not compete the same. Second, if you subsidize shipping by charging less than the label costs, the fee shrinks with it — the 10% is on what you charge, not on what the carrier costs.
This engine splits the fee into "on item" and "on shipping" rather than showing one total, because the shipping line is the one sellers can actually act on: it is the only part of the base you choose when you set the shipping charge.
Until January 6, 2025, Mercari charged a selling fee of 10% plus a payment-processing fee of 2.9% + $0.50 on every sale. The processing fee was eliminated on that date, leaving one flat 10%. The catch is that the internet's muscle memory outlived the fee: a large share of third-party Mercari calculators — and older blog posts and YouTube guides — still add both lines, overstating your fees by nearly $2 on a $50 sale.
| Sale (incl. buyer shipping) | What stale tools show | What Mercari actually charges |
|---|---|---|
| $30.00 | $3.00 + $1.37 = $4.37 | $3.00 |
| $50.00 | $5.00 + $1.95 = $6.95 | $5.00 |
| $100.00 | $10.00 + $3.40 = $13.40 | $10.00 |
The "phantom" column is 2.9% + $0.50 — the retired processing fee — added to the real 10% selling fee.
The overstatement is not small in margin terms. On a $50 item that cost you $25, two dollars of phantom fees is a tenth of your real profit — enough to reject a perfectly good offer because a calculator from 2024 said it was bad. If a tool shows you four or five fee lines, quotes a "payment processing" charge, or screenshots an interface with a separate deposit fee, it is describing pre-2025 Mercari.
This calculator charges 10%, once, on the order total including buyer-paid shipping — nothing else. If your actual settlement ever shows a second percentage line, check the date on whatever guide you are comparing against before checking your own math.
Mercari's stack is short enough to verify by hand, which is worth doing once. A $30 item sells with the buyer paying $8.00 of shipping, and the label costs you $8.00. Your gross settlement is $38.00 — item plus the shipping you collected. Mercari takes 10% of all of it: $3.00 on the item and $0.80 on the shipping, $3.80 together. The $8.00 label is deducted. What is left: $38.00 − $3.80 − $8.00 = $26.20, from which your $12.00 item cost leaves $14.20 of profit.
| Step | Amount | Running total |
|---|---|---|
| Item price | +$30.00 | $30.00 |
| Buyer-paid shipping | +$8.00 | $38.00 |
| Selling fee — item (10%) | −$3.00 | $35.00 |
| Selling fee — shipping (10%) | −$0.80 | $34.20 |
| Label cost | −$8.00 | $26.20 |
| Item cost | −$12.00 | $14.20 |
No processing fee since January 6, 2025 — this walkthrough is the complete stack, not a simplification.
Note where the profit margin lands: $14.20 on a $30 item is 47.3% — and the calculator computes the margin against the item price, not the $38 gross. That is deliberate. The shipping dollars are pass-through: they arrive and leave in the same breath, so counting them in your revenue denominator would flatter the margin on every heavy item you ship.
Because the fee is a bare 10% with no fixed component, the rate is the same at $5 and $5,000 — unlike Poshmark's flat tier or eBay's per-order fee, there is no price point where Mercari's cut suddenly grows. The only variable you control is the shipping charge, which is why the fee split — not the total — is this page's headline readout.
Depop removed its 10% selling fee in the US — sellers keep the full sale price. But buyers pay a marketplace fee of up to 5% + $1, and that checkout total is what your listing competes against. See both sides of the zero-fee model.
Vinted sellers keep 100% of the sale price — but buyers pay a Buyer Protection fee ($0.70 + 5% in the US, 3-8% in the UK), and that checkout total shapes what you can charge. Model your payout and the buyer's real cost side by side.

Mercari's flat 10% (charged on the buyer's shipping too) is one of the simplest fee schedules in e-commerce — which makes it a clean baseline. Run the same item through the three percentage-fee marketplaces and see which net payout wins.
One item, one form, all three fee schedules side by side — with the exact net payout on each, not three separate calculators to re-enter.
