FIRE — Financial Independence, Retire Early — is a movement built around one core principle: accumulate a corpus large enough that 4% annual withdrawal sustains your lifestyle indefinitely. With India's growing number of high-income professionals, FIRE is increasingly achievable in your 40s or even 30s. This calculator determines exactly how large your corpus must be and how much you need to save every month to reach it by your target retirement age.
The 4% Rule — Basis of FIRE Corpus
The 4% rule (from the Trinity Study) states that withdrawing 4% of a diversified portfolio annually is sustainable for 30+ years with high probability. So: FIRE Corpus = Annual Expenses / 0.04. If you need ₹60,000/month (₹7.2 lakh/year), your FIRE corpus is ₹7.2L / 0.04 = ₹1.8 crore. In India, many FIRE planners use a more conservative 3–3.5% withdrawal rate, given higher inflation.
Adjusting for Indian Inflation
India's inflation (5–6% p.a.) is higher than the US/Western inflation assumed in the original Trinity Study (~3%). This means your corpus needs to be larger, or you should use a lower safe withdrawal rate (3.5%). Our calculator adjusts your current monthly expenses to future values at the target retirement age using your assumed inflation rate, giving a more realistic picture.
The FIRE Journey in India
FIRE in India is accelerated by lower absolute living costs compared to Western countries, a large number of doctors/engineers/IT professionals with high savings capacity at early ages, and the growing availability of low-cost index funds (Nifty 50 index funds with 0.1–0.2% TER). The main risk is healthcare inflation — provisioning ₹20–50 lakh extra in a dedicated health emergency fund is widely recommended by Indian FIRE practitioners.
Frequently Asked Questions
What is the FIRE corpus for India?
Using the 4% rule at 6% inflation: if you need ₹50,000/month today and will retire in 20 years, your future monthly expenses will be approximately ₹1.6 lakh/month (₹19.2 lakh/year). FIRE corpus = ₹19.2L / 0.04 = ₹4.8 crore. The exact number depends on your lifestyle, family size, and retirement age.
What is Lean FIRE vs Fat FIRE?
Lean FIRE means retiring with a frugal lifestyle on a smaller corpus. Fat FIRE is retiring with a larger corpus that supports a comfortable/affluent lifestyle. Barista FIRE is a hybrid — you retire from full-time work but do part-time/freelance work to supplement the investment drawdown. In India, Barista FIRE is very common among early retirees.
What investments are best for FIRE in India?
A typical FIRE portfolio in India uses: 60–70% equity (Nifty 50 + mid-cap index funds), 20–30% debt (PPF, NPS, G-Secs), and 5–10% gold (Sovereign Gold Bonds). NPS is particularly useful as a FIRE instrument because of its 80CCD(1B) extra deduction and forced equity allocation.
How do I calculate my FIRE number?
FIRE Number = Annual Expenses at Retirement / 0.04 (using 4% rule). Annual Expenses at Retirement = Current Monthly Expenses × 12 × (1 + Inflation)^Years until retirement. Our calculator does this automatically — just enter your current expenses, expected inflation, and target retirement age.
