Show the calculation steps
- FIRE number = annual expenses ÷ withdrawal rate = ₹7,20,000 ÷ 4% = ₹1,80,00,000.
- Real return = (1 + 10%) ÷ (1 + 6%) − 1 = 3.77%, so everything is in today's money.
- Each month: balance = balance × (1 + real monthly return) + ₹60,000 saved, until it reaches ₹1,80,00,000.
- Progress today = ₹30,00,000 ÷ ₹1,80,00,000 = 16.7%. Income the current portfolio could support: ₹10,000 a month.
- The withdrawal-rate rule of thumb (for example 4%) comes from historical studies and is not a guarantee. Use a lower rate for a longer retirement.
What sets the age
Two things matter most: how much of your income you save and how much you need to spend. A high savings rate both builds the portfolio faster and shows you can live on less, which lowers the number you need.
Test different choices
Increase your monthly saving or lower your expenses and watch the age fall. Even small changes early can move the date by years.
Formula
Investments needed = Annual expenses ÷ Withdrawal rate
Age = Current age + years until the portfolio reaches that number
Each month: balance = balance × (1 + real monthly return) + saving
Where:
- Real return
- = (1 + return) ÷ (1 + inflation) − 1
