Welcome to iCalculator

Calculators are our passion

We know it's nerdy but calculators are our passion and we aim to make our calculators easy to use and understand. When practicable, we provide detailed breakdown of the calculations and supporting information so that you understand exactly how the calculator works and what information you need to know. A good example of this is our tax calculator, which provides a line by line calculation explanation, analysis and links to supporting information so that you can have a clear understanding of how your tax (PAYE, NIC's etc.) are calculated.

The iCalculator project was launched in 2009. In the early days iCalculator simply provided a few mathematical calculators. As the years have past, iCalculator has grown and grown and now provides dedicated advice and support (with tax guides, supporting articles and clarification of terminology). We have, and continue, to refine our calculators to provide more detailed breakdown, results and information so that you have the tool you need.
