What is IndCalculators?
IndCalculators is a growing collection of free online calculators for India. In one place you can work out your income tax, convert CTC into take-home salary, plan investments with SIP and lumpsum tools, project your EPF, NPS, PPF, FD and RD corpus, size up a loan with the EMI calculator, and handle everyday needs like GST, HRA and gratuity. Browse them all on the calculators page.
Every tool is free, needs no sign-up, and is private by design: the calculation runs entirely in your browser, so the figures you type never leave your device. Alongside the calculators we publish plain-English guides and timely updates that explain the rules behind the numbers.
Why we built it
Personal-finance decisions in India — your tax, your salary structure, your investments — often feel like a black box. Numbers appear on a payslip or a return, and most people accept them without seeing the working. When you can't check how a figure was reached, you have to take someone else's word for it.
We think that's backwards. Tax slabs, EPF rates, EMI formulas and compounding all follow clear, published rules — rules that can be followed, checked and explained. So we set out to build the tools we always wished we'd had: calculators that show the breakdown, paired with guides that explain each step. The goal is simple — when you can see how a number is calculated, you can trust it and make better decisions.
