Inflation matters most here. At 6%, your expenses double about every twelve years, so the amount you need looks large.

Frequently Asked Questions

Answers to common questions about this tool.

How much do I need to retire?

Commonly quoted as 25–30 times annual expenses, adjusted for inflation to your retirement date. Test the assumptions rather than trusting one figure — changing the return by two percentage points moves the answer enormously, and that sensitivity is the honest finding.

When should I start?

Now, and the arithmetic is unusually stark. Starting at 25 rather than 35 roughly doubles the final corpus for the same monthly amount, because the first decade of compounding does the most work. No later increase fully substitutes for it.

How accurate is Retirement Calculator?

It uses the standard formula for the calculation, so the maths is exact for the numbers you enter. For loans, tax and investments, treat the answer as a close estimate and confirm the final figure with your bank or adviser.

Does Retirement Calculator save the numbers I enter?

No. Your figures are worked out in the browser and are not sent to any server or stored in an account. Salary, loan and health details stay on your device.

Are the income tax calculators up to date?

They are built on the slabs published by the Income Tax Department for the year shown on each page. Rules change with each Budget, so confirm the figures on the official portal before you file.

Can I rely on these calculators for health decisions?

They are good for a quick check, such as BMI or daily calories. They are not a medical diagnosis, so talk to a doctor before changing medicine, diet or treatment based on a result.

Do I need to install an app?

No. Every calculator runs in the browser on your phone or computer, with no download and no sign-up. Bookmark the page if you use it often.
