Calculators

Updated on 12 April 2021

Resources

This page provides links to tax, tax credits, benefits and financial calculators provided by other websites. We take an active interest in calculators as tools to save people time and to help them to be self-sufficient.

It is important that calculators give the right answers. This is not always easy to do as the subjects are sometimes very complex and designers of calculators leave out difficult things on occasion.
