Stop Guessing. Start Simulating.
A standard spreadsheet uses a flat 6% inflation rate and ignores the 12.5% Long-Term Capital Gains tax. If you use a basic calculator to plan your Financial Independence and Early Retirement (FIRE) in India, you are walking blindfolded into a minefield.
You need a true simulation engine.
What is a FIRE Calculator?
A FIRE Calculator is a financial modeling tool that projects your current assets, savings rate, and future expenses over a multi-decade timeline to determine the exact year your investment corpus can indefinitely sustain your lifestyle without running out of money.
The Core Math of FIRE
The foundation of FIRE math is the Safe Withdrawal Rate (SWR). In India, due to higher baseline inflation (6-7%) and LTCG tax drag, a safe withdrawal rate is typically 3% — not the US-derived 4% Rule.
FIRE Number by Monthly Expenses
| Monthly Expenses | Annual Expenses | FIRE Corpus (3% SWR) | Equivalent Example |
|---|---|---|---|
| ₹40,000 | ₹4.8 Lakhs | ₹1.6 Crores | Lean FIRE, Tier-2 city |
| ₹75,000 | ₹9 Lakhs | ₹3 Crores | Regular FIRE, smaller metro |
| ₹1,25,000 | ₹15 Lakhs | ₹5 Crores | Chubby FIRE, Bangalore |
| ₹2,00,000 | ₹24 Lakhs | ₹8 Crores | Comfortable Fat FIRE |
| ₹3,00,000 | ₹36 Lakhs | ₹12 Crores | Full Fat FIRE |
Assumptions: 3% SWR, inflation-adjusted annual withdrawals, 40-year retirement horizon.

Launch the FIRE CalculatorWhy Indian Variables Make Generic Calculators Dangerous
To get an accurate result, your calculator must account for India-specific factors that US tools completely miss:
| Variable | Generic Calculator | plannF |
|---|---|---|
| Inflation rate | Flat 6% on everything | Separate rates: 6% lifestyle, 14% healthcare |
| LTCG tax | Ignored | 12.5% with ₹1.25L annual exemption |
| EPF access rules | Unknown | EPF locked until age 58 — modeled correctly |
| Old vs New Tax Regime | Not applicable | Full regime switch analysis |
| Currency | USD | INR (₹) native |
How to Use the plannF FIRE Simulator
- Input Your Assets: Enter current Equity Mutual Funds, FDs, and EPF balances. Do not include your primary residence.
- Define Your Expenses: Enter your current monthly expenses — we allow you to split by category for different inflation rates.
- Set the Rules: Adjust equity return expectation (default 12%), general inflation (default 7%), and healthcare inflation (default 14%).
- Run the Simulation: Watch the timeline instantly project the exact age your net worth crosses the "Freedom Line."
- Model Scenarios: Try "What if I reduce expenses by ₹20,000/month?" or "What if I take a 1-year sabbatical at 38?"

Watch the DemoHow Much Should You Be Saving? (The SIP Needed)
Working backward from the target corpus helps you figure out your required monthly SIP:
| FIRE Target | Years to FIRE | Required Monthly SIP (at 12% CAGR) |
|---|---|---|
| ₹3 Crores | 15 years | ₹64,000/month |
| ₹3 Crores | 20 years | ₹33,000/month |
| ₹5 Crores | 15 years | ₹1,07,000/month |
| ₹5 Crores | 20 years | ₹55,000/month |
| ₹5 Crores | 25 years | ₹28,000/month |
CAGR: 12%. No existing corpus assumed. Adjust for your starting corpus — each ₹1 Crore you already have today reduces the required SIP significantly.

1. Should I use a 3% or 4% SWR for my FIRE calculation?
Use 3% for India. The popular "4% Rule" was developed from Trinity Study data on US markets with 2-3% inflation. India's structurally higher inflation (6-7%) requires a more conservative withdrawal rate. For a 50-year retirement (retiring at 40), some experts recommend as low as 2.8%. See our detailed India SWR guide.
2. Should I include my EPF in the FIRE corpus calculation?
Include it, but only the portion accessible at your planned retirement age. EPF is locked until age 58 for most employees. If you plan to retire at 45, your EPF balance cannot be considered part of your immediately accessible retirement corpus — though it will be a significant asset a decade later. plannF handles this automatically by modeling EPF as a future-dated asset.
3. How does a FIRE calculator account for step-up SIPs?
A basic calculator assumes your monthly investment stays constant. A proper simulator like plannF lets you model step-up SIPs — where your monthly investment automatically increases by 10% each year alongside salary hikes. This dramatically improves your FIRE timeline and is far more realistic than assuming a flat SIP throughout your career.
4. What if I have existing loans (home loan, car loan)?
Loans reduce your investable surplus. In the FIRE calculator, you should input your net monthly savings after all EMI payments. Once a loan is paid off, the freed-up EMI amount should immediately flow into your investment SIP. Model this in plannF by setting a future date when the EMI disappears and the investment increases accordingly.
5. Can I model different income sources (rental income, part-time work) in the calculator?
Yes — in plannF, you can model multiple income streams during different phases of your FIRE journey. For example: full salary until 45, part-time consulting income (₹50,000/month) from 45-55, and zero active income from 55 onwards. This Barista FIRE or phased FIRE model dramatically reduces the corpus required.
