About Exmover

Exmover is a free collection of online calculators for money, health, math and everyday life. Every calculator is built to give a clear, accurate answer in seconds, with the working shown so you can understand the result.

What we believe

• Free for everyone. No account, no sign-up and no limits on use.
• Private by design. Calculations run entirely in your browser. The numbers you enter are never sent to a server.
• Transparent. Each calculator explains the formula it uses, and we use widely accepted methods such as the standard amortization formula, the WHO BMI ranges and the Mifflin–St Jeor equation.
• Fast on any device. Pages load quickly and work on phones, tablets and desktops, in light or dark mode.

How the calculators are checked

Every calculator is tested against worked examples before it is published, and the results are compared with the published formula. If you find a result that looks wrong, please tell us and we will investigate.

Important note

Results are estimates for planning and education. They are not financial, medical, legal or tax advice. For important decisions, check the figures with a qualified professional.
