What is FIRE?
FIRE stands for Financial Independence, Retire Early. The goal is to build a corpus large enough that the returns it generates can cover your living expenses indefinitely — making paid work optional rather than necessary.
The FIRE movement is built on one core insight: if you can reduce your expenses and invest the difference consistently, the point at which your investments fund your lifestyle arrives much earlier than a conventional retirement age.
What is your FIRE number?
Your FIRE number is the total corpus you need to be financially independent.
It is derived from the 4% safe-withdrawal rule, which suggests that a well-diversified portfolio can sustain annual withdrawals of about 4% of its value over a long retirement without depleting the corpus.
FIRE number = Annual expenses ÷ 4% = Annual expenses × 25
Worked example: If your monthly expenses are ₹50,000, your annual expenses are ₹6,00,000. Your FIRE number is ₹6,00,000 × 25 = ₹1,50,00,000 (₹1.5 Crore). Once your investments reach this size, withdrawing 4% per year covers your full annual expenses.
Note: this is a nominal estimate. The 4% rule originates from US research and may not directly apply to Indian market conditions, inflation rates, or investment horizons. Use it as a planning reference and review your plan periodically.
How does the FIRE calculator work?
The calculator takes four inputs and finds the time to reach your FIRE number.
First it calculates your FIRE number as 25 times your annual expenses. Then it grows your current savings and monthly investment contributions together at the expected annual return, compounding month by month, until the total corpus reaches your FIRE number. The result is the number of years needed to reach financial independence at your current savings rate and expected return.
How do I use Chola Securities' FIRE calculator?
Using the calculator takes four steps.
- Enter your monthly expenses — your current monthly living costs.
- Enter your current savings — the total investment corpus you already have.
- Enter your monthly investment — the fixed amount you invest each month.
- Enter your expected annual return — the return rate you expect from your portfolio.
The calculator instantly shows your FIRE number and how many years it will take to reach it at your current pace.
How can I reach FIRE sooner?
Three levers can shorten the time to financial independence.
Spending less reduces your FIRE number directly and also frees up more money to invest each month. It is the most powerful of the three levers.
Investing more each month grows your corpus faster and reduces the years remaining.
Earning a higher return on your portfolio shortens the journey — though higher expected returns should always be grounded in realistic assumptions about your asset allocation.

- See how changing your monthly investment or return rate changes the years to FIRE.
