The fee math (where it gets interesting)
On a $50 sale:
- Poshmark: $10 fee → you net $40 (buyer pays separate $8.27 shipping)
- Mercari: $5 (10%) + $1.95 (2.9% + $0.50) = $6.95 fee → you net $43.05 if buyer pays shipping
Mercari wins on raw fees at every price point above $15. But Poshmark's bigger fashion audience often pushes the sale price 20-40% higher — which more than makes up the gap on the right item.
Where Poshmark wins
- Women's fashion sells faster and higher. 80M users, mostly women, browsing daily.
- Designer items go for retail+. Lululemon, Free People, vintage Coach — Poshmark prices are unmatched.
- Flat shipping. Buyer always pays $8.27 — no shipping math, no surprises.
- Bundling. Buyers can build a bundle from your closet and get one shipping fee, lifting average order value.
Where Mercari wins
- Lower fees. Roughly 7% less on a $50 item.
- No sharing required. Poshmark expects 50-100 shares/day to rank; Mercari is set-and-forget.
- Anything goes. Electronics, books, toys, tools — Mercari sells the categories Poshmark ignores.
- Faster sales. Average listing sells 3-5x quicker.
The verdict
Women's fashion, designer, or curated styling: Poshmark. The premium prices and bundle dynamics beat Mercari's lower fees.
Everything else (men's, kids, electronics, general): Mercari. Lower fees, faster turnover, no daily-sharing tax on your time.
Best play: Cross-list. Most full-time fashion resellers run both, and use a tracker to see which platform sells each style faster.
