About This Calculator

Amazon fee calculators are everywhere, yet three problems never seem solved: rates go stale without anyone admitting it, tools sit behind sign-up walls or SaaS funnels, and “net profit” often quietly ignores storage and returns.

This site takes the opposite bet: every official number links to its Amazon source with the date it was checked, every unverifiable number wears an estimate badge and stays editable, and the full cost stack — referral, fulfillment, storage, returns, plan fee — is itemized on screen.

It covers Amazon.com, Amazon.co.uk and Amazon.in, runs entirely in your browser, and stores nothing server-side. It is an independent tool and is not affiliated with Amazon.
