Terms of use

By using Seller Profit Math you agree to these terms.

Estimates only

All results are rough estimates, not 100% accurate, not a guarantee and not financial, tax or legal advice. Fee figures are copied from platforms' public fee pages on the dates shown and may be out of date, may not match your category, country, plan or promotions, and some are marked as unverified. Your platform's own statement of fees is what counts. For tax questions, consult a qualified professional.

No warranty and limitation of liability

The site and every result are provided "as is" and "as available", without warranties of any kind, express or implied, including accuracy, completeness or fitness for a particular purpose. To the fullest extent the law allows, we are not liable for any direct, indirect, incidental or consequential losses arising from your use of the site or reliance on its results. This includes pricing, listing, tax and business decisions. Always verify numbers yourself before you act on them.
