Terms of use and disclaimer

The short version: our numbers are careful estimates, not a guarantee. Check fees in Seller Central before you spend money.

Last updated October 18, 2026

Estimates, not quotes

Every calculator and table on this site produces an estimate from Amazon's published US fee schedules and the inputs you provide. Amazon sets and changes its fees, measures your products itself, and may assign a different size tier, weight or fee category than you entered. The fees Amazon actually charges are the ones in your Seller Central account.
