Mercari Fee Calculator
See what a Mercari sale actually nets you — the flat 10% selling fee, itemized down to your true margin.
Flat 10% selling fee on item price plus whatever the buyer pays for shipping. No payment processing fee, no listing fee. If you offer "free shipping," leave shipping at $0 — your label cost is deducted separately and isn't part of this fee.
How this is calculated
Mercari selling fee is a flat 10% of item price plus whatever shipping the buyer pays — no tiers, no category rates, no minimums. There's no listing fee and, since Mercari's January 2025 fee change, no separate payment processing charge.
Free-shipping listings don't add anything to the fee base, since the buyer isn't paying for shipping directly — but the seller's actual label cost still comes out of the payout as a real cost, just not as part of this fee. That label cost varies by weight and carrier, so it isn't modeled here.
True margin is order total minus the selling fee — before your original cost for the item, any free-shipping label cost you absorbed, or cancellation/authentication fees on the rare sale where those apply.

Scope & limitations
Covers the standard 10% selling fee on a completed sale under Mercari's current (post–January 2025) fee structure. Not modeled: the old 2.9% + $0.50 processing fee that may still apply to un-updated pre-2025 listings, the 5%/$25-cap cancellation fee, authentication service charges ($5–$10), and the actual carrier cost of seller-absorbed "free shipping" labels. Treat this as a fee-stack estimate, not a final invoice.

Frequently asked questions
Does Mercari still charge a payment processing fee?
No. As of Mercari's fee structure change on January 6, 2025, the flat 10% selling fee is the only seller-side fee — there's no separate 2.9% + $0.50 processing charge. Older listings created before that date and never updated may still carry the old processing fee, but new and updated listings don't.
Is the 10% fee charged on shipping too?
Only on shipping the buyer pays. Mercari's fee base is item price plus buyer-paid shipping. If you offer "free shipping" and absorb the label cost yourself, there's no buyer-paid shipping amount, so the fee is 10% of the item price alone — your label cost comes out separately, not as part of this fee.
Are there any other seller fees on Mercari?
Listing is always free. Mercari does charge a cancellation fee (5% of item price, capped at $25) if a seller cancels a confirmed sale, and optional authentication services run $5–$10 per item — neither is modeled here since they don't apply to a standard completed sale.
Why isn't there a sales tax input?
Mercari collects and remits marketplace facilitator sales tax automatically in states that require it, and that tax isn't part of the seller's fee base or payout either direction — it passes through to the buyer and the state, so it doesn't affect what you keep.
