Calculators.icu is the online home of calculators for any occasion. Our goal is to provide fast, and easy calculations for simple and complex subjects that would normally require an amount of research to understand. Take for example, anything provided by HMRC, they have a lot of documentation, which can be used to understand the formula, but who really has the time to read it?

There are no sign-up fees, there's no registration, and all the calculations are free of charge.

At the time of writing tax related calculators are UK specific, however there will be examples that can be applied worldwide.
