    Frequently Asked Questions

    What is a FIRE number?

    A FIRE number is the total amount of money you need to have invested to achieve financial independence and retire early. It is calculated by dividing your annual expenses by your safe withdrawal rate (typically 4%).

    What is the 4% rule?

    The 4% rule is a retirement withdrawal guideline that suggests you can withdraw 4% of your retirement savings annually (adjusted for inflation) and have a high probability of your savings lasting 30 years. It was based on the Trinity Study.

    Can I retire at 45 in India?

    Yes, retiring at 45 in India is possible with careful planning. You need a substantial corpus (typically ₹2-5 crore depending on lifestyle), diversified investments, and a sustainable withdrawal strategy. Our FIRE calculator helps you determine your specific target.

    How much money do I need to retire in India?

    For early retirement in India, most FIRE seekers target ₹2-5 crore. This depends on your annual expenses, expected inflation, withdrawal rate, and lifestyle expectations. Use our calculator to find your personalized FIRE number.

    Is FIRE realistic in India?

    Yes, the FIRE movement is growing in India. With strong equity returns (12-15% historically from mutual funds), real estate appreciation, and disciplined saving, many Indians are achieving financial independence in their 40s. Key factors include high savings rates (40-60% of income) and smart investing.

    How much should I invest monthly for early retirement?

    The amount depends on your current age, target retirement age, and lifestyle. Generally, FIRE seekers aim to save 40-60% of their income. For example, a 30-year-old wanting to retire at 45 with ₹6L annual expenses needs to invest approximately ₹50,000 per month at 12% returns.

    What are the risks of early retirement?

    Key risks include inflation eroding purchasing power, unexpected healthcare costs, market volatility in early retirement years (sequence of returns risk), longevity (outliving savings), and lifestyle changes. Mitigation strategies include a diversified portfolio, health insurance, and flexible spending.

    How does inflation affect retirement planning?

    Inflation reduces the purchasing power of your savings over time. At 6% inflation, ₹1 crore today will be worth about ₹31 lakh in 20 years. Your FIRE number should account for inflation-adjusted expenses, and your investment strategy should target returns that outpace inflation.
