₹50,000 of current monthly expenses equals ₹6 lakh of annual present-day spending. A FIRE corpus reference divides that annual amount by a selected planning withdrawal rate.
Quick answer
At a 4% withdrawal-rate reference, the arithmetic is ₹6 lakh ÷ 4% = ₹1.5 crore. A different selected rate produces a different reference. The multiplier is simply the inverse of the selected rate.
This is a simple corpus reference under a selected withdrawal-rate assumption, not a retirement-success forecast. The calculation does not establish that ₹1.5 crore—or any other multiple—is enough.
What the reference omits
The FIRE calculation does not model:
- a future inflation path
- market volatility or sequence risk
- tax and product costs
- dynamic spending
- healthcare shocks or large goals
- pensions and other contractual income
- a retirement age, date, or probability
Retirement planning requires a horizon/longevity assumption, and actual lifespan can differ. Constant-return projections do not capture sequence-of-returns risk.
Illustrative scenario
Illustrative scenario: keep present-day annual spending at ₹6 lakh and compare several user-selected withdrawal-rate assumptions. Then test explicit inflation, return, withdrawal, and horizon assumptions in Retirement Readiness. The outputs are scenarios, not evidence that a corpus will last.
Common mistakes
- Calling the 4% planning reference a guarantee.
- Treating 25 times or another multiple as a universal target.
- Omitting taxes, healthcare, and future goals.
- Assuming an average return describes the order of annual returns.
What to do next
Use the FIRE Calculator for the simple present-day reference. Use Retirement Readiness and Wealth Withdrawal when you need assumption-visible projections and depletion mechanics.
