CalcPulse is a free website of online calculators and unit converters. We built it for people who want a quick, clear answer and want to understand how it was worked out.
What makes our calculators different
Every calculator shows its formula and the steps behind the result, so you can check the maths yourself. Calculators run in your browser, work on phones and computers, and can be installed on your phone like an app.
How we build and check them
Each calculator is written from its standard formula and tested against known examples before it is published. Pages explain the method in plain language and include a worked example. Where a result depends on local rules, such as tax or lending, we say so and ask you to confirm with an official source.
Corrections
