Reseller True-Profit & Fee Calculator
True net profit for resellers across eBay, Etsy, Poshmark, Mercari, Depop, Whatnot and TikTok Shop. Every fee itemised from current 2026 schedules, plus platform comparison and the minimum price that hits your target profit.
What did that sale actually make you?
Sale price is not profit. Each marketplace stacks different fees, and they changed a lot in 2026. This itemises every one, then subtracts shipping, what you paid for the item and supplies.
Platforms and fees covered (US, as of 2026-10-01)
- eBay: final value fee by category tier (standard, sports cards, handbags, watches, athletic shoes), per-order fee, Promoted Listings.
- Etsy: listing fee, 6.5% transaction, payment processing, Offsite Ads (15% or 12%).
- Poshmark: flat fee under $15, 20% above.
- Mercari: 10% selling fee.
- Depop: no US selling fee, payment processing, boosted listings.
- Whatnot: category commission plus payment processing.
