Retirement Planner
How much do you need for retirement?
Inputs
Your retirement plan
Years to retirement
Retirement duration
Monthly expense at retirement
Corpus needed at retirement
FV of existing savings
Additional corpus needed
Required monthly SIP
Assumes monthly SIP increases your corpus, no inflation step-up in SIP itself. For inflation-indexed SIPs, use the Step-Up SIP calculator.
How this works
Three numbers anchor any retirement plan: how much you spend today, how long you'll live in retirement, and what inflation does to your bills along the way. This calculator does three things in sequence:
- Inflates today's expense to retirement-age rupees — at 6% inflation over 30 years, ₹50,000/month becomes ~₹2.87 L/month.
- Computes the corpus needed to fund those inflated expenses for the full retirement period — accounting for the post-retirement portfolio still earning a return (typically lower, debt-heavy mix).
- Solves for the monthly SIP that gets you there given your pre-retirement return assumption and existing savings.
The 25× rule of thumb (and its limits)
A popular shortcut: corpus = 25× annual expenses (i.e., a 4% safe withdrawal rate). It's based on US equity returns over 30-year retirements. In India, with higher inflation and shorter equity history, a more conservative 30× is safer. This calculator does the full math instead of relying on the rule, so it accounts for your specific inflation, return, and longevity assumptions.
What to watch for
- Inflation kills retirement plans more than markets do. A 1% miss on inflation compounded over 30 years is a 35% miss on the corpus you'll need.
- Life expectancy is rising. Indian urban life expectancy is already ~75 and climbing — plan for 90 to be safe.
- Healthcare is your wildcard. This calculator assumes flat real expenses. In practice, medical bills spike in the last 10 years of life. Build a buffer.
- Sequence risk is real. A bad market in the first 5 years of retirement is far worse than the same drawdown later. Glide your asset allocation more conservative as retirement approaches.
