Free Online Calculators

Quick, accurate calculators for the questions you actually search for: what your loan EMI works out to, how much a SIP grows, your exact age from date of birth, GST on an invoice, income tax under the new vs old regime, BMI, percentages, and dozens more.

Every calculator shows its working — breakdowns, schedules, and charts where relevant — so you can sanity-check the number instead of trusting a black box. India-specific calculators (GST, gratuity, HRA, PPF, FD) follow the current official formulas and slabs.

Nothing to install and nothing to sign up for. Type your numbers, get the answer, copy it where you need it.

Common questions

Are the India tax and finance calculators up to date?

Yes. The income tax, GST, gratuity, HRA, PPF, and FD calculators follow the current rules and slabs, and are reviewed when budgets or rates change.

Can I rely on these for financial decisions?

They are accurate for the formulas they implement and great for planning, but they are educational tools — confirm large decisions with your bank or a qualified advisor.

Do the calculators work offline?

Once a calculator page has loaded, the math runs entirely in your browser, so it keeps working even on a flaky connection.
