Frequently asked questions

Is National Calculators free to use? +

Yes. Every calculator is free with no sign-up. Calculations run in your browser, so the numbers you type are never sent to a server or stored.

How accurate are the figures? +

Country-specific calculators use official government and tax-authority figures. Each one links to its source and shows the tax year it applies to. They are estimates for general guidance, not financial, tax or legal advice.

Which countries are covered? +

National Calculators covers the United Kingdom, Ireland, the United States, Germany, France, Spain, Italy, the Netherlands and Poland, with more added over time. Universal tools like BMI, percentages and loan maths work everywhere.

What languages can I use it in? +

The site defaults to English and offers each country in its main local language. Switch language or country from the top navigation at any time.

Who is behind National Calculators? +

National Calculators is built and maintained by Vikas Dulgunde, a software engineer, with every money figure sourced from official publications and dated to the year it applies to.
