SellerSum features and specs

• 13 fee and profit calculators
  Calculators for eBay, Etsy, PayPal, Stripe, Square, Whatnot, Depop, Poshmark and Mercari, plus margin, markup and food cost. A comparison hub puts every marketplace's cut side by side.
• Rates quoted from official fee pages
  Every rate comes from the marketplace's own published fee page, and each calculator shows the date it was last checked. The source link sits on the page, so you can confirm the number yourself instead of taking our word for it.
• Tested against the marketplaces' own examples
  Where a marketplace publishes a worked example, the calculator reproduces it to the cent. eBay's $400 phone example is one of them, and a unit test fails the build if it ever stops matching.
• Fee changelog and email alerts
  Every fee change is logged with the date it landed. Sign up and you get one email when any tracked marketplace moves its rates, whichever calculator you use.
• Free, no signup
  Every calculator is free and works without an account. Nothing is behind a paywall.
