Mercari vs Poshmark Fees (2026): Same Item Compared

Fee by fee, side by side

Same item, three price points

The $10 row is the story: Mercari leaves you $9.00 where Poshmark leaves $7.05 — the flat fee's 29.5% bite. Above $15, Poshmark's 20% is exactly double Mercari's 10%, so the dollar gap grows linearly with price. The only wrinkle: Mercari's fee base includes buyer-paid shipping, so "free shipping" listings dodge that slice on Mercari while Poshmark's commission never touches shipping at all.

Which items belong where

• Under $15: Mercari, always — or bundle on Poshmark past the threshold.
• Everyday fashion $15–$60: cross-list both; Poshmark's feed often moves it faster despite the 10-point premium.
• Non-fashion (home, toys, electronics): Mercari — Poshmark's audience isn't shopping for it.
• High ticket: Mercari's flat 10% caps your exposure; Poshmark takes a fifth of everything.

The shipping difference

Shipping is where these two fee books stop being comparable. Poshmark hands every order a prepaid flat-rate USPS label the buyer pays by default — dead simple for anything under the weight allowance, and the seller's only fee exposure is voluntary: the shipping discounts you attach to offers come out of your payout. Mercari's approach is more flexible and more dangerous: labels are cheaper per weight tier and can be buyer- or seller-paid, but picking the wrong tier (or buying retail off-platform) quietly eats the 10% you saved on fees. The discount habit compounds the same way: Poshmark buyers expect shipping offers, and each $4.99 discount is effectively another 16.6% fee on a $30 sale. Sellers who run the same inventory on both platforms usually find Poshmark's shipping wins on simplicity and loses on flexibility — and that the "fee winner" flips once label subsidies and weight classes enter the math. Price the label before you price the item; on both platforms the shipping decision is worth more than the commission decision.

The payout-timing footnote

Neither platform holds your money long, but they differ on the last mile: Poshmark's direct deposit is free and lands in a few days, while Mercari's Instant Pay costs $3 per transfer (standard deposit stays free). Habitual instant-cash-out users hand back a slice of the fee advantage one $3 charge at a time — on a $30 sale, that's another 10%. The comparison table above assumes patient, free payouts on both; if you always tap "instant," Mercari's real take is 10% plus $3 per transfer, and the gap to Poshmark narrows accordingly.

The honest caveat

Fee math says Mercari; your closet's turnover may disagree. Poshmark's buyer base pays the 20% without flinching because the feed moves items — and an item sold beats an item listed. Use the calculator for the floor, then let sell-through data pick the winner.
