Frequently asked questions

Are the calculators free to use?

Yes. Every calculator on Helpful Calculators is completely free, with no sign-up, account or app download required. They run entirely in your browser.

Do I need to create an account or share any personal data?

No. There is no sign-up and the calculations happen locally in your browser, so the figures you enter are not sent to a server. Any values you save are stored only on your own device.

Are the calculators specific to the UK?

Yes. The financial tools use UK tax rules, rates and thresholds — including the separate systems for England, Scotland, Wales and Northern Ireland where they apply. Results are estimates to help you plan and are not financial advice.
