Free Amazon Seller Tools & Calculators

This is the free tools section of the Goat Consulting site, where we build calculators and estimators that answer the numbers questions Amazon sellers run into every week. You'll find in-browser tools for estimating FBA fees, checking profit margin on a new product, and sanity-checking the math before you commit inventory to a SKU. Every tool is built in-house by a member of our team who has run these same calculations for brands across dozens of product categories, so you get an answer you can trust in under a minute without a login, a signup, or a demo.

Most sellers land here while deciding whether a product is worth listing or working out why a SKU's margin is thinner than expected, so the tools below are meant to be a quick-reference check you can come back to every time Amazon changes a fee or you evaluate a new product. If you'd rather have the Goat Consulting team review your fees, margins, and account performance in depth instead of working through it yourself, reach out.
