Handy Calc is a small collection of free, fast calculators for everyday questions about money, dates, health and measurements.
Every calculator runs entirely in your browser. The numbers you type are not sent to us or stored anywhere.
We explain the formula behind each tool so you can check the maths yourself. Results are estimates for general information and are not financial, medical or legal advice.
