Same $40 item.
Nine platforms. $8.00 of difference.

Every marketplace describes its fee differently — a commission here, “payment processing” there, a buyer-side fee somewhere else. The only comparison that means anything is what lands in your account. So here is one $40 sale, no shipping charged, run through every platform this calculator supports.

$40 item, nothing charged for shipping, fees as published in August 2026. DoorDash is left out because it is a gig payout, not a marketplace sale — there is no seller fee to compare.

Reading the table honestly

Vinted keeps the most in your pocket on this sale and Poshmark the least — a $8.00 gap on a single $40 item, or 20% of the sale price. Across a hundred sales a year that is $800.00.

But the cheapest fee is not automatically the most money. A platform that takes 20% and sells your item in three days beats a platform that takes nothing and never sells it. Fees decide your margin; the audience decides whether there is a sale to take a margin on.

Where the ranking flips

  • Cheap items.Fixed fees dominate. A $6 sale costs $0.65 on Depop (10.8%) but $0.60 on Mercari (10.0%) and nothing on Vinted — while Poshmark's flat $2.95 under $15 takes 49% of it.
  • When you charge for shipping.Etsy, eBay, Whatnot and Mercari all charge their percentage on the postage the buyer pays. Add $8 shipping to this $40 item and eBay's fee rises from $5.84 to $6.93.
  • Vinted's 0%. Genuinely zero for sellers, but buyers pay a ~5% + $0.70 protection fee on top of your price, which is money leaving the transaction that you never see. Compare on what the buyer spends, not on the seller fee alone.
  • Offsite Ads. Etsy's $4.25 becomes $10.25 on this item if the sale is attributed to Offsite Ads — which would move it below Poshmark.
