What is FIRE (Financial Independence, Retire Early)?
FIRE is a movement focused on achieving financial independence—the ability to cover all living expenses through passive income without working. The goal is to retire decades earlier than the traditional 65-year retirement age. Instead of working 40 years and retiring at 65, FIRE followers aim to retire at 35-45.
The FIRE Promise: Build enough wealth that your investments generate income exceeding your expenses. Once achieved, you can stop working and live off investment returns forever.
The Math Behind FIRE
The 4% Rule
Research shows that withdrawing 4% of your invested corpus annually is sustainable indefinitely. This accounts for inflation and market downturns.
Example:
- Annual expenses: ₹30,00,000
- FI Number (corpus needed): ₹30,00,000 / 0.04 = ₹75,00,00,000 (₹7.5 crore)
- At 8% annual returns: ₹7.5 crore generates ₹60,00,000 annually (4% withdrawal) = ₹5,00,000/month
Calculating Your FI Number
| Annual Expenses | FI Number (÷0.04) | Years to FIRE (at 30% savings rate, 12% returns) |
|---|---|---|
| ₹6,00,000 (₹50K/month) | ₹1,50,00,000 | 8-10 years |
| ₹12,00,000 (₹1L/month) | ₹3,00,00,000 | 12-15 years |
| ₹24,00,000 (₹2L/month) | ₹6,00,00,000 | 16-20 years |
| ₹36,00,000 (₹3L/month) | ₹9,00,00,000 | 18-22 years |
