About EasyCalcs

EasyCalcs is a collection of free, fast online calculators for questions that come up in everyday life: how much zakat do I owe this year, what is my exact age, how many days until my deadline, is my weight in a healthy range, and how do I work out this percentage.

We built EasyCalcs around three principles. Simplicity — each tool does one job with no clutter, no signup and no downloads. Transparency — every calculator explains the formula behind it in plain English so you can check the result yourself. Privacy — all calculations run inside your own browser; the numbers you type are never uploaded to any server.

The site is free to use and supported by advertising. If you spot an error or have an idea for a calculator we should add, we would love to hear from you on the contact page.
