About Seller Fees Calc

Seller Fees Calc is a small independent site that builds free fee and profit calculators for people who sell online, from weekend resellers to full time shops.

Most fee calculators are lead magnets for paid software. They ask for your email, hide the math, or quietly use last year's rates. We wanted the opposite: open calculators that show every fee line by line, link to the official source, and say when they were last checked.

How we check fees

Every rate comes from the platform's own fee page or help center, never from another calculator. The date of our last full check is shown on every calculator. When a platform announces a change, we update the calculator and the explanation on the same page.

Independence

We are not affiliated with eBay, PayPal, Venmo, Etsy, Whatnot, Mercari, Poshmark, Depop or TikTok. Their names are used only to describe which fees each calculator works out. The site is paid for by ads.
