Email is the only channel: hello@sellerfeecalculators.com. We usually reply within two business days. There is no contact form, chat widget, or phone line, and we do not ask for an account or a newsletter signup before you write.

Report a fee that does not match your statement

Every rate on this site is read from the platform's own published fee schedule and dated on the calculator page. Schedules still change, and a calculator can fall behind between the announcement and the day we apply it. If a number here disagrees with what you were actually charged, email us. Include:

That is enough to check the source, update the calculator if the schedule changed, and record the old and new rates on the fee change log. We do not need your seller account, order ID, or payout history.

Ask how a calculation works

If a line on a payout slip looks wrong, say which calculator you used and which input you are unsure about (category, shipping, sales tax, or item cost). Most mismatches come from the fee being taken on more than the item price, or from a category that uses a different rate than the default. We will point at the specific rule, not a generic percentage.

For eBay specifically, the complete fee schedule lists every category rate we model. The calculator at the eBay fee calculator applies those rates to your own numbers, including the per-order fee.

Request another marketplace

If you sell on a platform that is not listed yet and you want a calculator for it, say which one and, if you can, link the official fee page. We add platforms when the schedule is public, stable enough to model, and used by enough sellers that a dedicated page will get used. A request is not a promise of a date.

What we cannot help with

This site is independent. It is not affiliated with, endorsed by, or sponsored by any marketplace or payment provider named here. We cannot reverse a fee on your account, reopen a case, change a payout, or talk to a platform on your behalf. For those, you have to use that platform's own seller support.

We also cannot give tax advice, tell you whether a sale is reportable, or estimate income tax from a payout. Net payout here means what the platform deposits after its own fees. It is not after-tax profit.

Bug reports

If a calculator fails to update, a number looks rounded wrong, or a page breaks on your device, include the browser and a short description of what you entered and what you expected. A screenshot helps when the payout slip is the thing that looks off.
