Calculation Methodology & Rules

The FIRE Calculator projects when you will achieve financial independence and be able to retire early based on your savings rate and SWR.

1. The FIRE Number Formula

Your target corpus is determined by dividing your annual living expenses by your safe withdrawal rate:

FIRE Number = Annual Expenses / (SWR % / 100)

For example, if your annual expenses are ₹6 Lakhs and your SWR is 4% (0.04), your target is:
₹6,00,000 / 0.04 = ₹1,50,000,000 (1.5 Crore).

2. Compounding & Monthly Contributions

We run a month-by-month projection growing your current savings at a monthly rate of Expected Return / 12 and adding your monthly investment until the target is reached.

To understand how inflation affects these numbers, you can cross-reference with our Inflation Calculator to adjust your future expenses.

For detailed rules, formulas, references, and official guidelines, see the complete Ganakam Calculation Methodology.

Frequently Asked Questions

Your FIRE (Financial Independence, Retire Early) number is the total corpus you need to retire early. It is calculated by dividing your annual expenses by your safe withdrawal rate. At a standard 4% withdrawal rate, your FIRE number is exactly 25 times your annual expenses.

You can retire as soon as your total investment corpus meets or exceeds your FIRE number. This calculator estimates how many years it will take based on your current savings, monthly investments, and expected return rate.

The Safe Withdrawal Rate is the percentage of your retirement corpus you can withdraw annually without running out of money, typically adjusted for inflation each year. 4% is a widely accepted guideline globally (the Trinity Study), though some prefer a conservative 3% to 3.5% for longer early retirements.
