- The Threat of Inflation: A monthly expense of ₹50,000 today inflates to a massive ₹2,14,594 by age 55 at a 6% inflation rate.
- Post-Retirement Return: In retirement, your corpus must be invested conservatively (e.g., debt funds/FDs yielding 8%) to minimize risk.
- Capital Depletion Model: This calculation assumes you consume both interest and principal, leaving a balance of ₹0 at age 85. Adjust assumptions upward to leave an inheritance.

The FIRE Number You Calculated Is Probably Wrong — Here's How to Fix It
Most FIRE calculators give you a single number: "You need ₹X crore to retire." The problem is that number is usually calculated in today's rupees — as if inflation doesn't exist for the next 20-30 years of retirement. It does. And it's relentless.
Indian inflation averages 5–7% for general expenses, but healthcare inflation runs at 10–14% per year. A ₹1 lakh/month retirement lifestyle today will cost ₹3.2 lakhs/month in 20 years at 6% inflation. Your corpus needs to generate ₹3.2 lakhs/month by then — not ₹1 lakh/month.
This is where the Inflation-Adjusted FIRE calculator differs from basic tools. It asks: What is your inflation estimate before retirement? What is your inflation estimate during retirement (usually higher, due to medical expenses)? What return do you expect your corpus to generate during the withdrawal phase?
The result is a more accurate target corpus — often 40–60% higher than what basic calculators suggest. This is uncomfortable but important. Planning for ₹3 crore when you need ₹4.8 crore means running out of money at age 74 instead of 85. The earlier you know your real number, the more time you have to adjust your savings rate.
Retire on facts, not optimistic assumptions.
