Compare seller fees: one item, six marketplaces
The same sale, run through all six fee schedules at once. This is a comparison of published fees under the standard assumptions below — each platform's own calculator page has the full options (categories, tiers, promotions).
Poshmark ignores the shipping input — its buyer pays for a prepaid label and its commission is on the sale price only. Mercari's Buyer Protection fee (3.6%) is paid by the buyer and is not subtracted from the Mercari payout.
| Platform (assumptions) | Total fees | You keep | Effective rate |
|---|
Standard assumptions: eBay “most categories” · Whatnot Standard tier, most categories · Etsy without Offsite Ads · Depop US seller without Boost (Depop rates are Reported — see its calculator page). Fees verified Oct 19, 2026; each platform's source is stamped on its own page.
Fees are only one part of selling on a platform — audience, sell-through speed, and shipping rules differ, and this page says nothing about any of those. It answers exactly one question: for this item at this price, what does each platform's published fee schedule take?
