How Multi-Platform Fees Work

This calculator compares configured fees across the supported selling platforms:

PlatformFee StructureBest For
eBay13.6% + $0.30/$0.40 for most categoriesCategory and amount tiers vary
Mercari10% of item price + buyer-paid shippingNo separate processing fee under the current structure
Poshmark20% at $15 or above; $2.95 under $15Seller-funded shipping adjustments are separate
FB Local0% platform-fee assumptionPayment and other costs may apply

Pro Tips

  • Treat the comparison as fee-assumption arithmetic, not a sell-through forecast
  • Remove listings from other platforms immediately when an item sells
  • Use Facebook local pickup for heavy or bulky items to avoid shipping
  • Confirm category, payment, shipping, and account-specific fees before listing
