Ecom Fee Calculator

About This Site

Free, independent fee calculators for people who sell online.

Ecom Fee Calculator exists to answer one question well: how much of this sale do I actually keep? Platform fee pages are long and spread across several help articles, and many calculators online are out of date, hide the working, or ask for an email before showing a result. This site does the opposite.

How We Verify Rates

  • Every rate is read from the platform's own pricing page, help center, or official announcement. We do not copy rates from other calculators or blogs.
  • Each fee is stored once, in a versioned data file, together with what it applies to, any threshold or cap, its effective date, and the official source link. The calculators, explanations and FAQs all read from that file, so they can't disagree with each other.
  • Each calculator shows the date the rates were last checked and links to the sources, so you can check them yourself.
  • If we cannot confirm a fee on an official page, we leave it out and say so on the page. A missing fee you know about is better than a wrong one.

What the Calculators Don't Cover

The calculators estimate the standard fees for a single order or payment. They do not include optional advertising you buy directly, shipping labels purchased through a platform, refunds or chargebacks, currency exchange on payouts, income tax, or custom pricing you may have negotiated. Your platform statements are always the final word.
