FIRE Number Calculator – How Much Money You Need To Retire Early
This is not financial advice. Always consult a certified financial planner before taking action.
Most people dream of retiring early – sitting on a sunny beach at 45 instead of sitting in traffic at 65. But how much money do you actually need to make that happen? The FIRE movement (Financial Independence Retire Early) gives us a simple and powerful formula to calculate that magic number – your FIRE Number.
In this article, we will break down the formula, show real-world examples, create step-by-step instructions, and help you understand exactly what you must save and invest to exit the rat race early.

What Is a FIRE Number?
Your FIRE Number is the total amount of money you need invested so you can live off your investment returns instead of working. It represents financial independence – when money works for you, not the other way around.
The classic formula to calculate FIRE number is:
FIRE Number = Annual Expenses × 25
This formula assumes a sustainable 4% withdrawal rate – meaning you can take out 4% of your total portfolio every year and your money should last 30+ years.

Why Does the FIRE Number Matter?
Most people save blindly. They don’t know how much money is enough. Once you calculate your FIRE number, everything becomes clearer:
- You know exactly how much you must save.
- You know when you can retire.
- You can choose work by passion, not compulsion.

How To Calculate Your FIRE Number (Step-by-Step)
Step 1: Calculate Your Monthly & Annual Expenses
First, list everything you spend money on:
- Rent / housing
- Groceries
- Transport (fuel / metro / car maintenance)
- EMIs or loans
- Entertainment
- Insurance
- Healthcare
Example monthly budget:
| Expense Type | Monthly Cost (₹) |
|---|---|
| Housing (Rent) | ₹15,000 |
| Food & Groceries | ₹10,000 |
| Transport | ₹5,000 |
| Insurance & Health | ₹3,000 |
| Other Lifestyle Spending | ₹7,000 |
Total = ₹40,000/month = ₹4,80,000/year
Step 2: Multiply Your Annual Expenses by 25
Using the 25× rule:
₹4,80,000 × 25 = ₹1,20,00,000
Your FIRE Number = ₹1.2 Crore
Step 3: Adjust for Inflation
If you're planning to retire in 20 years, inflation matters. At 5% yearly inflation, expenses double in approx. 14–15 years. So your FIRE number must be higher to remain safe.
Step 4: Add Safety Margin
Most financially careful planners add a buffer of 10–20% extra.
Revised FIRE number:
₹1.2 Crore + 20% buffer = ₹1.44 Crore needed to retire early

Examples of FIRE Number for Different Lifestyles
| Monthly Cost | Annual Expense | FIRE Number (×25) |
|---|---|---|
| ₹25,000 | ₹3,00,000 | ₹75,00,000 |
| ₹40,000 | ₹4,80,000 | ₹1,20,00,000 |
| ₹60,000 | ₹7,20,000 | ₹1,80,00,000 |
| ₹1,00,000 | ₹12,00,000 | ₹3,00,00,000 |
How Much Should You Save Per Month To Reach FIRE?
Use this simple calculation:
Total Fire Number ÷ Years to FIRE ÷ 12 = Monthly Savings Needed
Example:
Goal = ₹1.2 Crore
Target time = 20 years
₹1,20,00,000 ÷ 20 ÷ 12 = ₹50,000/month (without investment returns)
But investments grow! With an average return of 10% per year, you only need around:
₹18,000/month (approx.) to reach ₹1.2 Crore in 20 years
Where Should You Invest Toward Your FIRE Number?
Everyone’s risk tolerance varies, but common FIRE-friendly investments include:
- Index Funds / ETFs (core growth engine)
- REITs – passive rental income
- Government Bonds – low risk stability
- Dividend Stocks – recurring income
- Gold ETFs – hedge against inflation
Sample Allocation for FIRE Portfolio:
| Asset Type | Allocation % |
|---|---|
| Index Fund | 50% |
| REITs | 20% |
| Government Bonds | 10% |
| Dividend Stocks | 10% |
| Gold ETF | 10% |
How To Make Your FIRE Number Smaller (Faster Retirement Tips)
You can either earn more or need less. The second part is easier. To reduce the FIRE number, consider:
- Living in a smaller city instead of a metro
- Cooking at home more often
- Using public transport
- Avoiding lifestyle inflation
- Buying used cars instead of EMIs

FIRE Number Calculator For Couples
If two people share expenses, the FIRE number becomes surprisingly lower than calculated individually.
Example:
- Combined monthly cost: ₹60,000
- Annual = ₹7,20,000
- FIRE Number = ₹1.8 Crore
Per person responsibility for FIRE = ₹90,00,000
FAQs
1. How accurate is the FIRE number calculator?
It gives a strong estimate, but real life changes. Inflation, lifestyle, and unexpected expenses can change your real needs.
2. Is the 25× rule safe?
It is widely accepted, but many experts suggest increasing it to 27–30× for extra safety.
3. What if I want luxurious retirement?
Increase your FIRE number – larger expenses require a bigger corpus. The math stays the same.
4. Can I retire early without investments?
No. Savings alone lose value due to inflation. Investments are the engine that creates early retirement wealth.
5. Should I include children's education cost in expenses?
Yes – anything that costs money during retirement must be included in your FIRE calculation.
6. What if returns drop in the future?
Having a buffer (20–30%) protects you. Also diversify investment types.
Conclusion
Your FIRE number is your financial compass. Once you know it, you know where to go and how fast you need to move. Whether your goal is ₹75 lakh or ₹3 Crore, early planning makes it achievable.
