How much retirement corpus do I need?
Tell us the monthly income you want and when it should start. We work backwards — inflating your spending every single year, medical costs faster than the rest — to the smallest corpus that actually funds it. No 25× rules of thumb, no signup, nothing stored.
Your target income
Your corpus
Simple applies one flat rate (8%) to your whole corpus. 3-bucket uses real asset-class returns — safe money for near-term spending, equity (10%) for the long bucket, sold only after it has gained. Both end up assuming roughly the same equity exposure, so this is a like-for-like comparison. Buckets come out modestly ahead on average — and considerably ahead if markets fall early.
Withdrawals grow every year — general spending at 6%, the medical 15% at 10% — while the remaining corpus earns 8%. Never a flat number.
Simple vs 3-bucket, on your numbers
Same corpus, same spending, same horizon — the only thing that changes is how the money is held and which pot you sell from.

How the corpus calculator works
- Say what you want to spend per month, in today's money, and the age the income should start.
- We grow that spending forward — general costs at 6%/yr, the medical slice at 10% — right through to the age you plan to.
- We search for the smallest corpus that survives every one of those years, simulating the drawdown rather than applying a multiple.
- You get two numbers — the corpus needed when withdrawals begin, and what you'd need invested today to reach it — plus the monthly SIP that closes any shortfall.

Frequently asked questions
How much corpus do I need to retire in India?▾
There is no single number — it depends on what you spend, when you stop, and how long you plan for. The honest way to get it is to work backwards from your spending: take the monthly income you want in today's money, grow it with inflation every year to the age your plan ends, and find the smallest pot that funds all of it.
That's what this calculator does, year by year, rather than applying a rule of thumb like 25× or 30× annual expenses. Those multiples come from US studies at US inflation rates; at India's ~6% general and ~10% medical inflation they tend to understate what you need.
