The 4% rule doesn't survive Indian inflation: how to size a real FIRE number

Financial independence has a famous shortcut: save twenty-five times your annual expenses and withdraw 4% a year. It comes from US research built on US inflation, US asset returns and a thirty-year horizon. Each of those three assumptions is wrong for an Indian professional retiring at forty-five.

Three reasons the number is too small

• Inflation. Your headline inflation is not your personal inflation. Education, healthcare and domestic help — the three costs that dominate an Indian household's later years — have run persistently ahead of the index.
• Horizon. Retiring at forty-five with a reasonable life expectancy is a forty-plus year drawdown, not thirty. The withdrawal rate that survives thirty years does not automatically survive forty.
• Sequence risk. A poor first five years does disproportionate damage, because you are selling units to eat at exactly the wrong time. The average return over thirty years can be fine while the plan still fails.

What we actually model

For Indian households we work from a withdrawal rate in the region of 3% to 3.5% rather than 4%, which moves the target from twenty-five times expenses to roughly twenty-eight to thirty-three times. On an annual spend of ₹18 lakh that is the difference between ₹4.5 crore and something closer to ₹5.5 crore — a gap large enough that discovering it at fifty is a problem and discovering it at thirty-five is a plan.

We also model the corpus in two buckets: a stability bucket sized to cover three to five years of spending, and a growth bucket. The stability bucket exists so that a bad market never forces a sale.

The lever that matters

The surprising part, every time: your savings rate decides the timeline far more than your returns do. Save half your income and independence is roughly fifteen to seventeen years away. Save a third and it is closer to twenty-five. Two extra percentage points of return move that by a year or two; ten extra points of savings rate move it by the better part of a decade.

The part a spreadsheet will not tell you

Tax treatment on withdrawal, the order in which you draw down different pots, what happens to health cover when you leave employment, and whether your spouse's plan is the same plan. These are the questions that separate a number from a roadmap.

Run the calculator on our services page to get an honest first number. Then come and argue with it — that conversation is where the actual planning starts.

One caution about the corpus itself. A number that assumes you never help a parent with a medical bill, never fund a child's education abroad and never take a career break is not a plan; it is a spreadsheet. We model those as explicit line items with their own timing, because they are the events that actually happen to Indian households during the decade in which people are trying to retire.
