In the Indian context, FIRE is less about not working and more about having the freedom to work on your own terms. It's the point where your accumulated investments generate enough passive income to cover your living expenses indefinitely.

• It estimates your FIRE corpus, which is the total savings you need, based on your desired monthly expenses.
• It accounts for long-term inflation to ensure your future income maintains its purchasing power.
• It uses a 'Safe Withdrawal Rate' (SWR) of 3-4% to calculate a sustainable income from your corpus.
• It projects how long it will take to reach your goal based on your current investments and returns.

The withdrawal rate is the percentage of your corpus you withdraw each year. A rate of 3.5% means for every ₹1 crore saved, you can safely generate an income of ₹3.5 lakhs per year. A lower rate is safer and makes your money last longer, while a higher rate is riskier and can deplete your savings, especially during market downturns.

• Family Size: More dependents mean higher expenses and a larger required corpus.
• Lifestyle Expectations: A lavish lifestyle requires a much larger FIRE number than a simple one.
• Healthcare Costs: Unplanned medical expenses can significantly impact your corpus.
• Inflation: Higher inflation means you need a larger corpus to maintain the same standard of living.
