Frequently asked questions
Which takes less, Poshmark or Mercari?
Mercari, at every price point under the classic default rates. Its ~12.9% + $0.50 stack sits well under Poshmark's flat 20%, and under $15 Mercari's percentage also beats Poshmark's $2.95 flat fee. The gap is roughly 7% of the sale price above $15 — real money on higher-value items: about $5 kept per $80 sale.
Why does Poshmark charge so much more than Mercari?
The 20% is all-inclusive and funds a different model: payment processing is bundled (Mercari bills it separately), shipping runs on Poshmark's prepaid priority-label system, and the social "posh party" machinery drives discovery. Whether that is worth 7 points depends on your inventory — mainstream and premium apparel often realizes enough extra on Poshmark to cover the difference.
Is Poshmark ever the better payout despite the higher fee?
Yes, whenever its buyers pay more. The fee gap on a $30 item is about $1.63, so if the same piece sells for $33+ on Poshmark — common for popular brands with strong comp prices there — Poshmark wins despite the rate. Compare realized prices for your actual brands, not just the fee lines, before committing a closet to one platform.
Do these fees change often enough to re-check?
Yes. Mercari removed and reinstated selling fees within 2024 alone, and Poshmark trialed a buyer-fee structure the same year before rolling it back. Every rate on this page is an editable field precisely so the comparison survives the next restructure: plug in the current numbers from each platform's fee page and read the fresh gap.
