About Feesplain

Free tools for sellers and freelancers to see exactly where their money goes.

Platform fee pages are long, scattered and change often. Feesplain turns them into calculators that show every fee line by line, so you can price confidently and know your real profit before you list.

How we keep fees accurate

Each calculator uses the platform's standard published US rates, with the date we last checked them shown on the page. Platforms offer category exceptions, promotions and different rates outside the US, so always compare with your final statement.

Your data

Calculator inputs are only used to compute your result. The invoice generator runs entirely in your browser: your invoices are saved on your device and never uploaded.

Estimates only, based on standard published US fees for typical transactions. Category exceptions, promotions, currency conversion, chargebacks and taxes can change what you actually pay. Not financial or tax advice.
