Frequently asked questions
Are these finance calculators free to use?
Yes โ all tools are free, require no sign-up and run instantly in your browser.
Do the tax and salary tools reflect current rates?
They implement published official rates and thresholds, and each page names its sources and the period they apply to. Rules change, so always double-check critical cases.
Is my financial data uploaded anywhere?
No. Every calculation happens locally in your browser; nothing you enter leaves your device.
Are the results financial advice?
No. The tools produce mathematical estimates and cannot consider your full situation. They are a starting point, not a recommendation.
Which countries do the tax tools cover?
Alongside country-agnostic tools there are dedicated sets for Japan (income tax, social insurance, residence tax) and the UK (income tax, NIC, SDLT, council tax and more).
