About HandySums

HandySums is a free collection of everyday calculators and tools: loan repayments, income tax, fuel costs, BMI, unit conversions, PDF tools and more. Everything works in your browser, with no sign-up.

Made for where you live

Many sums depend on your country. Tax brackets, currency, how cars are rated for fuel, even BMI cut-offs. HandySums lets you switch between Global, South Africa and India, and each tool tells you which rules it is using.

How we keep the numbers right

Tax tables, VAT and GST rates and example fuel prices are checked against official and reputable sources, and each tool says when its figures were last checked. Calculations follow standard published formulas. If you spot a mistake, please tell us and we will fix it.
