eBay vs Poshmark Profit Calculator

Compare eBay and Poshmark seller fees, payout, net profit, and match-price deltas for the same resale item before you decide where to list.

This v1 reuses the shipped EastSea fee engines for eBay and Poshmark. It holds item economics constant, compares the same realized item price, and keeps eBay shipping / tax / promoted-rate assumptions explicit.

Scenario inputs

Enter a scenario to compare both platforms.
  • The same negotiated item price is used on both sides for the core comparison.
  • eBay keeps buyer shipping, sales tax rate, and promoted listings drag explicit.
  • Poshmark keeps seller shipping discount explicit and applies the shipped US baseline fee rule.
  • Other seller cost is folded into eBay’s packaging-cost lane because the shipped eBay module has no separate other-cost field.
