How much do I need for FIRE?
Your FIRE number is 25 times your annual expenses. If you spend $50000/year you need $1.25 million. If you spend Rs 50000/month (Rs 6 lakh/year) you need Rs 1.5 crore. At Rs 1 lakh/month expenses you need Rs 3 crore. This assumes a 4% annual withdrawal rate which has historically sustained portfolios for 30+ years through all market conditions.
How to achieve FIRE in India?
With a Rs 1 lakh monthly salary saving 50% (Rs 50000/month) in equity mutual funds earning 12% you can reach Rs 1.5 crore in approximately 12 years. Living frugally investing aggressively and increasing savings with each raise are the three pillars. Many Indian FIRE enthusiasts achieve financial independence by age 40-45 with a corpus of Rs 2-3 crore.
What is the 4% rule for FIRE?
The 4% rule states you can withdraw 4% of your portfolio in the first year of retirement and adjust for inflation each year with minimal risk of running out in 30 years. Based on the Trinity Study of US stock and bond returns this means a $1 million portfolio supports $40000/year. In India with higher returns some experts suggest a 3-3.5% withdrawal rate for additional safety.
