About CalcHub
CalcHub is a collection of free, simple calculators for everyday money, health and writing questions.
What we do
We build calculators that are quick to use and clear about what they assume. Every tool shows its working, so you can check the figures.
How it works
All calculations run in your browser. The numbers you type are not sent to our servers and are not stored.
Accuracy
Results are estimates for planning. They are not financial, tax, medical or legal advice. For a loan, insurance or tax decision, confirm the figures with your bank, adviser or the official source.
