About EasyCalcBox

EasyCalcBox is a collection of free online calculators for everyday questions about money, health, dates and maths. We started it because most calculator websites are slow, full of pop-ups and do not explain how they get their answers.

What we believe in

• Clear answers. Every calculator shows the result as you type, with the formula behind it and a worked example.
• Privacy. Calculations run in your browser. We do not store what you enter.
• Accuracy. Tax rates and rules are checked against official sources, and each page shows when it was last reviewed.
• Your language. EasyCalcBox is available in English and German, with French, Italian and Spanish coming soon.

How we are funded

The site is free to use and is paid for by advertising. Ads never change the results of a calculator.
