Worked example

Calculated by the same engine as the calculator above.

Inputs
Annual Expenses
₹6,00,000
Withdrawal Rate (%)
3.5
Result
FIRE Number
₹1,71,42,857
Annual Expenses
₹6,00,000
Withdrawal Rate
3.50%

Formula

FIRE number = Annual expenses / (w / 100)

  • Annual expenses = yearly spending you want the corpus to fund
  • w = withdrawal rate (%): 3.5% by default for ₹, 4% for other currencies

Assumptions

  • The FIRE number is annual expenses divided by the withdrawal rate; at 3.5% that is about 28.6 times annual expenses, at 4% it is 25 times.
  • Inflation, taxes, market returns and the length of retirement are not modelled.
  • The withdrawal rate is your assumption; the 4% rule comes from historical studies and may not fit Indian conditions or long retirements.
  • A withdrawal rate of 0 cannot produce a valid number.
  • Educational estimate only, not financial advice. Capitallytics does not execute transactions.

FIRE Calculator FAQ

Answers about how this calculator works.

What is the 4% rule?
It suggests withdrawing about 4% of your corpus in the first year of retirement. A 4% rate means you need 25 times your annual expenses.
Is 4% a safe withdrawal rate in India?
It is a rule of thumb from historical studies, not a guarantee. Higher inflation or a long early retirement may call for a lower rate, so try 3% or 3.5% too.
Should I use current or future expenses?
The calculator uses whatever you enter. If you retire years from now, inflate today's expenses with the Inflation calculator first.
How do I know how long it will take to reach my FIRE number?
Use the Savings Goal calculator with the FIRE number as the target, your current savings and monthly contribution.
