Note
Please don’t email us personal payslip data — your name, personal ID number, or exact amounts. A sample is enough for a rough estimate: the site has no account, no sign-up and no form, and the calculation stays in your browser. Google Analytics 4 does run on every page, but without cookies, and it only ever sends Google the page address, the referrer, an approximate location derived from your IP address, and your device and browser type — never what you type into the calculator or the content of an email you send us.
