Mercari vs Poshmark Fees 2026: Which Is Actually Cheaper?

The two fee structures

Mercari and Poshmark take opposite approaches to seller fees:

• Mercari: A flat 10% selling fee on every sale, with a $1.00 minimum — so anything selling for $10 or less effectively pays $1.00. No separate payment-processing fee since it was folded into the flat rate on January 6, 2025.
• Poshmark: A bracket system — $2.95 flat on sales under $15, and 20% of the sale price on sales of $15 or more. No separate processing fee on top.

On paper, Poshmark's flat $2.95 fee for low-priced items looks like the better deal below $15. It isn't. Mercari's flat 10% fee has a $1.00 minimum, so even a very cheap item stays capped at $1.00 — well under Poshmark's flat $2.95.

Side-by-side fee comparison

Mercari = flat 10%, $1.00 minimum, no separate processing fee. Poshmark = $2.95 flat under $15, 20% at/above $15. All USD. Verify your own numbers in the Poshmark calculator and the Mercari calculator.

Why there's no breakeven point

You'd expect a crossover somewhere — a price where the cheaper platform flips. There isn't one, and with Mercari's current flat-rate structure the reason is simple arithmetic in both directions. Under $15, Mercari's fee is 10% of price with a $1.00 minimum, which tops out at $1.50 right at the $15 mark — always below Poshmark's $2.95 flat fee for that bracket. At $15 and above, Poshmark switches to a flat 20%, exactly double Mercari's flat 10%, so Mercari's fee is mathematically always half of Poshmark's from that point on. Mercari wins in both brackets, for two different (and both very clean) reasons.

So why do sellers still choose Poshmark?

If fees were the only variable, this wouldn't be a close call. But sell-through rate usually matters more to your total profit than the fee percentage on any single sale. Poshmark built its business around social selling — follows, shares, "Posh Parties," and a buyer base that's heavily concentrated in women's fashion, shoes, and accessories. For those categories, Poshmark's discovery engine can move inventory faster than Mercari's more traditional, search-based marketplace, even though Poshmark keeps a bigger cut of each sale.

Mercari's strength is breadth — electronics, home goods, collectibles, and general merchandise all perform reasonably well there, and its lower, more predictable fee schedule rewards sellers who already have consistent demand for what they're listing.

The practical takeaway: don't pick a platform on fees alone. If you're deciding between the two for a clothing item with strong Poshmark-style appeal, model both fee totals, but weight sell-through probability more heavily than the fee gap — a faster sale at a lower net payout usually beats a slower sale at a higher one.

Common mistakes sellers make comparing these two

• Assuming Mercari's fee is always exactly 10%. A $1.00 minimum applies to every sale, so anything priced at $10 or below actually pays a higher effective rate than 10% — a $5 item pays a $1.00 fee, a 20% effective rate.
• Assuming Poshmark's 20% only applies above $15. It applies to the entire sale price once you cross $15, not just the amount above it — a $15.01 sale is taxed at 20% on the full $15.01, not just the one cent over the threshold.
• Ignoring shipping cost differences. Poshmark's buyer-paid flat shipping ($8.27 US) can make items feel more "final price" competitive than Mercari, where sellers often set their own shipping. Factor this into your total pricing strategy, not just the seller fee.
• Comparing fee rates instead of net dollars. A lower percentage on a platform where your item won't sell for months isn't actually cheaper. Compare expected net profit, weighted by how likely the item is to sell on each platform.
