FIRE — Financial Independence, Retire Early — has a devoted following built mostly around US cost-of-living and market assumptions. The core math still applies in India, but a couple of the standard assumptions need adjusting before the numbers mean anything.
What your FIRE number really is
The FIRE number is the corpus that lets you withdraw enough to cover annual expenses indefinitely, typically calculated as 25x your annual expenses (the inverse of a 4% withdrawal rate). Spend ₹8 lakh a year and the target is ₹2 crore — not a random round number, but a direct function of your own spending.
Why the 4% rule needs an Indian adjustment
The 4% safe withdrawal rate was derived from US market history. Indian equity markets have historically offered higher long-term returns but with higher volatility, and inflation has historically run hotter than the US. A more conservative 3–3.5% withdrawal rate is a safer assumption for an India-based retirement lasting 40+ years, which raises the actual target corpus by 15–30% over the naive 25x calculation.
Savings rate is the real lever
The timeline to FIRE is driven far more by savings rate than by investment returns. Someone saving 50% of income can plausibly reach FIRE in ~17 years; at a 30% savings rate that stretches past 25 years — a bigger swing than any realistic difference in fund performance. Increasing savings rate does double duty too: it grows the corpus faster and lowers the annual expense target it needs to cover.
Fat FIRE, Lean FIRE, Coast FIRE
Not all early retirement looks the same. Lean FIRE targets a frugal, minimal-expense lifestyle with a smaller corpus. Fat FIRE preserves a higher, more comfortable spending level and needs a proportionally larger number. Coast FIRE is a middle path — save aggressively early, then let compounding alone carry you to full retirement while working a lower-stress, lower-income job in between.
