How much do you actually need to retire in India?

"How much do I need to retire?" is usually answered with a multiple — twenty-five times expenses, thirty times, a round crore. Every one of those numbers is someone else's answer to a question with four of your inputs in it. The arithmetic is not hard, and doing it yourself is the difference between a plan and a wish.

The four inputs, and which one dominates

Your annual expenses at retirement — not today's. This is the input people get wrong, and it is the one the answer is most sensitive to. Take today's annual spending, subtract what stops (the EMI that ends, the children's education, your own retirement contributions), add what starts (healthcare, which rises faster than general prices), then inflate the result to your retirement date. The inflation calculator does the last step; a 6% assumption roughly triples a number over twenty years.

Years the money must last. Not to life expectancy — past it. Planning to the average means a coin-flip chance of outliving the plan. Thirty years past a retirement at 60 is the usual honest floor.

The return you can expect after retiring, on a portfolio that is necessarily more conservative than the one that got you there.

Inflation during retirement, which does not stop on your last working day. A corpus that funds year one exactly and grows at the inflation rate funds year thirty exactly. One that does not, does not.

The retirement calculator takes all four; the financial freedom calculator runs the full lifecycle including the drawdown.

What the multiples are actually saying

The familiar "25×" comes from the 4% rule — the observation that a portfolio withdrawn at 4% of its starting value, inflation-adjusted, historically survived thirty years in US data. The Indian caveats are substantial and are worked through in the 4% rule versus an SWP: different inflation history, different asset return series, a shorter reliable dataset.

Treat a multiple as a sanity check on arithmetic you have done, never as a substitute for it. If your own calculation lands wildly away from 25-30× your retirement-year expenses, the input to re-examine is usually the expense estimate, not the return assumption.

Two adjustments the headline number ignores, both real:

Subtract what you already have coming. EPF balance, NPS corpus, gratuity, a property that will be sold, an SCSS floor. The gap you must fund with an SIP is the target minus these, not the target.

Add a health buffer outside the corpus. A medical event funded by selling equity in a bad year is the mechanism by which retirements fail, which is sequence-of-returns risk arriving through the back door.

The number is a direction, not a destination

The single most useful property of this calculation is that redoing it annually costs an hour and changes the plan while changing it is still cheap. The inputs move — your spending, your horizon, the market — and a corpus target computed once at 35 and never revisited is a number about a person who no longer exists. Fold it into the annual portfolio audit.

And a target you cannot fund today is still worth computing. Knowing you are at 40% of the required SIP is actionable in a way that "I should save more" never is — that gap is the input to your 30-year wealth blueprint.

⚠️ Every figure here depends on assumptions about inflation, returns and longevity that no one can guarantee. These are planning tools, not forecasts; WealthTicker is not a SEBI-registered investment adviser.

Key takeaway

Four inputs — retirement-year expenses, years the money must last, post-retirement return and ongoing inflation — and the first one dominates the answer. Compute it yourself rather than adopting a multiple, subtract the EPF, NPS, gratuity and other pots already coming to you, keep a health buffer outside the corpus, and redo the whole thing once a year. A target you cannot yet fund is still the most useful number in your plan.
