What is a FIRE Calculator?

FIRE stands for Financial Independence, Retire Early. It is a personal finance movement where you build a corpus (accumulated wealth) large enough that your investment returns permanently cover all your living expenses β€” so you never need to work for money again.

In India, FIRE is gaining massive traction among millennials tired of the 9-to-5 grind. Whether you want to quit at 35, start your own business, travel full-time, or simply have the security of knowing you could stop working anytime β€” FIRE gives you that freedom.

Your FIRE number is the total corpus you need. Once you know this number, every investment decision becomes sharper.

How is it calculated?

The FIRE number is calculated using the safe withdrawal rate (SWR) concept:

FIRE Number = Annual Expenses at Retirement Γ· Safe Withdrawal Rate

The classic US 4% rule gives: FIRE Number = Annual Expenses Γ— 25

For India, adjusted for higher inflation (6% vs 2-3% in US), the safe withdrawal rate is 3-3.5%, giving:

India FIRE Number = Annual Expenses Γ— 28 to 33

Our calculator uses a more precise present value formula accounting for your specific retirement age, life expectancy, and post-retirement return assumptions, giving you an accurate India-specific FIRE number.

How to use this calculator

1. Enter your current age and target FIRE age
2. Enter your current monthly expenses β€” the calculator inflation-adjusts this to your FIRE age
3. Enter your current savings/corpus β€” include all investments: mutual funds, EPF, PPF, NPS, stocks, FDs
4. Enter your monthly SIP β€” how much you invest every month currently
5. Set pre-FIRE CAGR (use 12% for equity-heavy portfolio) and post-FIRE return (use 7-8% for conservative post-retirement allocation)
6. Set inflation (6%) and life expectancy (85 is standard)
7. Calculate to see your FIRE number, projected corpus, and whether you are on track

Frequently asked questions

What is a realistic FIRE age for India?β–Ύ
Most Indian FIRE seekers target 40-50 years, compared to 35-45 in the US. This is because of higher family obligations, no universal healthcare, and the need for a larger corpus to handle Indian inflation. FIRE at 45 is very achievable for a dual-income family saving 40%+ of income.
How much corpus do I need to retire in India?β–Ύ
A rough estimate: multiply your current monthly expenses by 300-400 to get your FIRE number. If you spend β‚Ή50,000/month today, you need β‚Ή1.5-2 crore at today's value, but inflation-adjusted to your retirement age. Our calculator gives the exact number.
What should I invest in to reach FIRE?β–Ύ
For the accumulation phase (pre-FIRE): 70-80% equity (Nifty 50 index funds + flexicap), 20-30% debt. For post-FIRE: shift to 50% equity + 50% FD/bonds + Sovereign Gold Bonds. SWP (Systematic Withdrawal Plan) from equity funds is the most tax-efficient withdrawal method.
Is EPF and PPF counted in FIRE corpus?β–Ύ
Yes. Include your EPF balance, PPF balance, NPS balance, mutual fund portfolio, stocks, and FDs in the current corpus field. Exclude the market value of your primary residence unless you plan to downsize and rent.
What is Lean FIRE vs Fat FIRE?β–Ύ
Lean FIRE means retiring on a frugal lifestyle (β‚Ή30,000-50,000/month). Regular FIRE means maintaining your current lifestyle. Fat FIRE means retiring with luxury spending (β‚Ή1-2 lakh/month). Barista FIRE means semi-retiring with part-time income covering some expenses. Our Lean/Fat FIRE calculator compares all four.
