Using the tools
FeeFinderMate provides estimates for the marketplace scenarios described on each page. Results depend on the values and settings you choose. You are responsible for checking that the seller type, category, rate period and VAT assumptions fit your transaction.
Estimates and official charges
Published fees can change and account-specific charges may differ. Confirm important estimates with the marketplace’s official tools and your account records before buying stock or making pricing decisions. The calculators do not provide accounting, tax or financial advice.
Availability and corrections
We may update fee schedules, correct errors or change features. We do not promise uninterrupted access or a match to every transaction. If you find an issue, contact us with enough information to reproduce it.
Independent service
FeeFinderMate is not affiliated with or endorsed by Amazon, eBay or TikTok. Marketplace names are used to identify the relevant tools and sources.
Content and permitted use
You may use the calculators for your own estimates and link to the site. Do not misuse the service, attempt to interfere with its operation or present FeeFinderMate estimates as official marketplace charges.
Responsibility
To the extent permitted by applicable law, FeeFinderMate does not accept responsibility for losses arising from decisions made using these estimates. Nothing in these terms excludes rights or responsibilities that cannot legally be excluded.
