About these calculators
The money calculators cover common questions: how much tax each regime leaves you with, what goes into your EPF each month, how much of your HRA is exempt, and what a loan EMI or a SIP works out to. Each one prints its formula, plus the official source and check date for any rate it uses, so you can follow the working. Treat the results as planning estimates, not tax or investment advice. The everyday calculators do quick sums: BMI, age on a date, days between two dates, percentages and discounts.
You can use all 31 without an account. To jump to one, type part of its name in the filter box above.
