BizMargin exists to give small business owners, freelancers, and professionals access to a free profit margin and markup calculator for Amazon sellers and small business owners — completely free, with no account required and no data stored on our servers.
Too many business tools are bloated, expensive, or buried behind paywalls. We believe the tools that power good business decisions should be accessible to everyone — whether you're a solo freelancer or a growing team.

Oliver built BizMargin as part of the Boring Factory — a collection of free, focused utility tools for business owners. Just useful software, free to use.
We take your privacy seriously. BizMargin does not store any data you enter into the tool. All calculations happen locally in your browser. We use Google Analytics for anonymous usage statistics and Google AdSense for advertising. See our Privacy Policy for full details.
