Plan your retirement

“How much is enough?” is the most important money question most people never answer. This retirement calculator takes your current expenses, inflation, the years until you retire and how long retirement may last, and works out the corpus you'll need — then the monthly investment that gets you there, after counting what you've already saved in EPF, PPF, NPS or mutual funds.

How to use it

  1. Enter your age, when you want to retire, and the age you want your money to last until.
  2. Enter today's monthly household expenses (excluding EMIs that will end before retirement).
  3. Adjust inflation and the expected returns before and after retirement.

How it's calculated

  1. Expense at retirement = today's expense × (1 + inflation)years to retirement.
  2. Corpus = the amount that, earning the post-retirement return, can pay that expense every month — rising with inflation — until your planned age.
  3. Monthly investment = the SIP that grows to (corpus − future value of current savings).

Example

A 30-year-old spending ₹50,000 a month, retiring at 60 and planning till 85, with 6% inflation, 11% returns before and 7% after retirement, and ₹5 lakh saved, needs a corpus of roughly ₹7.7 crore. That calls for a monthly SIP of about ₹23,000. Starting at 40 instead nearly doubles it, to about ₹44,500 a month — the strongest argument for starting early. Check individual pieces with the EPF,NPS and SWP calculators.

Frequently asked questions

How much money do I need to retire in India?
It depends on your expenses, inflation and how long retirement lasts. This calculator inflates today’s monthly expense to your retirement date, then works out the corpus needed to keep paying that rising expense until the age you plan for, while the corpus earns a conservative return.
What return should I assume before and after retirement?
Before retirement, a diversified equity-heavy portfolio has historically returned roughly 10–12% a year over long periods (not guaranteed). After retirement, money usually shifts to safer debt and hybrid options, so 6–8% is a more realistic planning figure.
Why is the required corpus so large?
Inflation. At 6%, expenses roughly double every 12 years, so a ₹50,000 monthly budget today becomes nearly ₹2.9 lakh a month in 30 years — and keeps rising through retirement.
Does it include EPF, PPF or NPS?
Enter what you have already saved for retirement in “Current savings” — including EPF, PPF and NPS balances — and the calculator grows it to your retirement date before working out the gap.
