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.
  • TikTok Shop: referral fee (8% for most categories since Aug 2026), per-order fee, affiliate commission.

Tools

  • calculate_net_profit: every fee line, net profit, margin, ROI, what you keep.
  • compare_platforms: the same item on all seven, ranked by net profit.
  • find_breakeven_price: the lowest list price that reaches your target profit.
  • get_fee_schedule: the schedule used, with the date and official page to verify.

Fees change often. Every result carries its as-of date, and you can pass custom_fee_pct or custom_flat_fee to adjust for anything that has changed or applies to your account. Sales tax and income tax are not included.
