Why the US 4% Rule Fails in India
The famous Trinity Study established the "4% Rule" based on 70 years of US market data with 2–3% inflation.
In India, lifestyle inflation runs at 6.5% to 8.0%. If you withdraw 4% adjusted for 7% inflation each year, a bad market sequence in the first 5 years will deplete your corpus in under 25 years.
The Indian FIRE Formula: The 33x Rule
$\text{Target Corpus} = \text{Annual Essential Expenses} \times 33$
If your family lives comfortably on ₹12 Lakhs/year:
$\text{Target Corpus} = 12\text{L} \times 33 = \mathbf{₹3.96 \text{ Crores}}$
The 3-Bucket Deployment Architecture
1. Bucket 1 (Cash Buffer - 3 Years of Expenses): ₹36 Lakhs in Liquid Funds / Sweep FDs to fund monthly living expenses with zero market stress.
2. Bucket 2 (Income Stability - 7 Years of Expenses): ₹84 Lakhs in Target Maturity Debt Funds & Corporate Bonds yielding steady 7.5%.
3. Bucket 3 (Long-Term Growth - Remainder): ₹2.76 Crores in Nifty 50 & Global Equities compounding uninterrupted for the next 20+ years.
