FIRE Calculator – Financial Independence Retire Early Calculator
The FIRE (Financial Independence, Retire Early) calculator helps you determine when you can stop working by calculating the corpus needed to sustain your expenses indefinitely. It factors in your savings rate, investment returns, and desired withdrawal rate to project your path to financial freedom.

What Your Results Mean
Your FIRE number is the corpus that, when invested, can generate enough returns to cover your annual expenses indefinitely at your chosen withdrawal rate. The years to FIRE tells you how long it will take at your current savings rate. To reach FIRE faster, either increase your savings rate or reduce your annual expenses — both have a direct impact.
What This Calculator Does
Enter your current savings, annual income, annual expenses, expected return rate, post-FIRE return, and safe withdrawal rate. The calculator shows your FIRE number (target corpus) and how many years until you reach it.
How the Calculation Works
The FIRE number is calculated as your annual expenses divided by your safe withdrawal rate. The calculator then projects how long it will take your current savings plus annual investments to reach that target, given the expected returns.
Calculation Logic (Simplified)
FIRE Number = Annual Expenses / Safe Withdrawal Rate. Years to FIRE = calculated iteratively based on annual savings and compounded growth.Example Calculation
Annual expenses of ₹6,00,000 with a 4% withdrawal rate means your FIRE number is ₹1,50,00,000 (₹1.5 crore). If you save ₹5,00,000/year and earn 12% returns, you could reach FIRE in about 14 years.
When to Use This Calculator

- You're evaluating how your savings rate impacts your early retirement timeline
- You're comparing different withdrawal rates to find a sustainable FIRE target

Common Mistakes to Avoid
- Using the US-centric 4% rule without adjusting for India's higher inflation and different market conditions — 3–3.5% may be safer
- Not factoring in healthcare costs which rise significantly with age and inflate at 10–12% in India
- Underestimating post-FIRE expenses — lifestyle inflation, travel, and unexpected costs often increase spending
- Ignoring the impact of sequence-of-returns risk — a market crash early in FIRE can permanently damage your corpus
- Not planning for taxes on withdrawals from equity and debt investments

Assumptions and Limitations
Assumptions
- Annual expenses remain constant in real terms after achieving FIRE
- The safe withdrawal rate is sustainable over a 30–40 year retirement period
- Investment returns are constant both before and after FIRE
- No additional income is earned after achieving financial independence
Limitations
- The calculator uses constant return assumptions — real markets are volatile and sequence of returns matters
- Healthcare costs, which are the biggest wildcard in FIRE planning, are not modeled separately
- Tax on withdrawals (LTCG, STCG) is not factored into the withdrawal rate
- The 4% rule was derived from US data — its applicability to Indian markets and inflation is debated
- Lifestyle changes, family obligations, and unexpected expenses are not accounted for
