FIRE stands for Financial Independence, Retire Early. The core idea is simple: if you save enough money that your investment returns can cover your living expenses forever, you never need to work again unless you want to. The most common benchmark is the 4% rule, which says you can withdraw 4% of your portfolio each year indefinitely without running out of money.
Your FIRE number is simply your annual expenses divided by your withdrawal rate. If you spend ₹6 lakh a year and use the 4% rule, your FIRE number is ₹1.5 crore. The calculator factors in your current savings, monthly investments, and expected return to tell you how many years away you are from hitting that target.
Frequently Asked Questions
What is the 4% rule?
The 4% rule comes from the Trinity Study (1998), which found that a portfolio of 60% stocks and 40% bonds could sustain withdrawals of 4% per year for at least 30 years in almost all historical scenarios. Many FIRE practitioners in India adjust this to 3-3.5% to account for longer retirements and different market conditions.
Should I account for inflation?
Yes. The simplest way is to reduce your expected return by your inflation estimate. If you expect 10% returns and 6% inflation, use 4% as your real return in the calculator. This gives you an inflation-adjusted projection.
What's a realistic return to expect in India?
Nifty 50 has historically delivered around 12-13% CAGR over long periods. After taxes and costs, 10-11% is a reasonable expectation for equity investments. Debt/fixed income returns are typically 6-8%. A blended portfolio might target 8-10%.
Is 4% withdrawal rate safe for early retirement in India?
The original Trinity Study was based on US market data for 30-year retirements. If you're retiring at 35, you might need a 50+ year portfolio. Many Indian FIRE followers use 3-3.5% to be safer. The calculator lets you adjust the withdrawal rate.
