What FIRE means in the Indian context
FIRE stands for Financial Independence, Retire Early — building a corpus large enough that investment income covers your living expenses indefinitely, freeing you from needing a paycheck. In India this usually means a higher savings rate than the original US FIRE movement assumed, because structural inflation here runs 6–7% versus 2–3% in developed markets, and there is no direct equivalent of Social Security to fall back on. Most Indian FIRE followers do not stop working entirely — they use the corpus to leave a stressful full-time job for more flexible, lower-stress, or passion-driven work.
Why this calculator uses a lower Safe Withdrawal Rate than the US 4% rule
The famous "4% rule" comes from the Trinity Study, built on decades of US market and inflation data. Applied directly to India, it understates how fast expenses grow: at 4% withdrawal with 7% inflation, a ₹2Cr corpus can run out in as little as 20–22 years. This calculator defaults to a 3.5% Safe Withdrawal Rate — equivalent to roughly a 28.5× annual-expense multiple — which survives 30–40 year retirements with meaningfully less sequence-of-returns risk. You can adjust the SWR slider yourself if you want a more conservative (lower %) or aggressive (higher %) target.
Step-by-step: using the controls on this page
- Enter your monthly expenses — not your salary. Your FIRE number depends entirely on what you spend, not what you earn.
- Set your current age and target retirement age to fix the number of years this plan has to compound.
- Adjust the Safe Withdrawal Rate if you want a different corpus-to-expense multiple than the India-adjusted 3.5% default.
- Add your current corpus — existing EPF, mutual funds, stocks, or FDs already working for you — to see how much less you need to save from here.
- Add any children's goals (education, wedding) with their expected age and cost, and set a health corpus for post-retirement medical inflation.
- Read the FIRE Number headline, the monthly SIP needed, and the corpus accumulation chart to see whether your current trajectory gets you there.
Reading your results
- Your FIRE Number — the total corpus you need at retirement, in future (inflation-adjusted) rupees.
- Monthly SIP needed — how much you must invest each month, from today, to reach that number by your target age.
- Years to FIRE — how long it takes at your current savings pace, given the return and inflation assumptions above the chart.
- Coast FIRE badge — appears when your existing corpus alone, left to compound with no further contributions, already reaches your FIRE number by your target age.
- Corpus breakdown — splits your total target into lifestyle corpus, health corpus, and any children's goals, each inflated independently to the year it's needed.
Worked example: Priya, 30, ₹60,000/month expenses, retiring at 45
Priya is 30, spends ₹60,000/month today, and wants to retire at 45 — 15 years away. At 6% inflation, her expenses grow to roughly ₹1.44L/month by then. This calculator's default 3.5% Safe Withdrawal Rate puts her lifestyle corpus at ₹4.9Cr; adding a ₹20L (today's value) health corpus — inflated at 8–10%/yr to ₹47.9L by retirement — brings her total FIRE number to ₹5.4Cr. Starting from ₹0 saved, she needs to invest about ₹1.1L/month (at 12% expected pre-retirement return) to get there. Her Coast FIRE number — what she'd need invested today, untouched, to still hit ₹5.4Cr by 45 — is just ₹98.8L, because 15 years of compounding does most of the work. Change any of Priya's numbers — expenses, ages, corpus — in the calculator above to see your own version of this math.
Lean, Coast, Standard, or Fat FIRE — which target applies to you
"FIRE number" isn't one fixed multiple — it depends on the lifestyle you're targeting, and the Lean / Coast / Standard / Fat toggle above the FIRE number on this page switches between them directly, recalculating your SIP, years-to-FIRE, and chart for whichever you pick. Lean FIRE targets essential expenses only, at a 20× annual-expense multiple. Standard FIRE uses this calculator's India-adjusted 3.5% SWR (about 28.5×) by default — adjustable via the Safe Withdrawal Rate pills in the sidebar. Fat FIRE assumes an upgraded lifestyle at a 50× multiple. Coast FIRE is a different question entirely: not "how big a corpus do I need at retirement," but "how much do I need invested today, with no further contributions, to grow into that number by my target age" — for Priya above, that's ₹98.8L versus her ₹5.4Cr retirement-day target. See Retireopedia: FIRE for the full breakdown of each variant.
How existing EPF, NPS, and market investments count differently toward your number
Not all corpus is equally liquid or equally taxed. Provident fund and pension money (EPF, VPF, PPF, NPS) compounds tax-efficiently but is partly locked until specific ages or events, and NPS mandates a minimum annuity purchase at exit. Market investments (equity mutual funds, direct stocks, FDs) are fully liquid but carry capital gains tax on withdrawal and more volatility. Real estate can anchor net worth but rarely funds monthly expenses without selling or renting it out. When you enter your current corpus into this calculator, it's worth mentally splitting it across these three buckets first — see the EPF vs NPS calculator and EPF-to-retirement-corpus calculator to understand how much of your provident fund balance is really available for early, pre-60 FIRE spending versus locked until statutory retirement age.
Should you prepay your home loan or keep investing toward FIRE?
This trade-off comes up constantly in Indian FIRE planning. Prepaying a home loan gives a guaranteed, risk-free return equal to your loan's interest rate (often 8–9%), with no market risk and no tax on the "return." Investing the same money in equity has historically returned more over 15+ year horizons, but with real volatility and sequencing risk right when you need the money. As a rule of thumb: if your loan rate is close to or above your realistic long-term equity return assumption, prepayment is often the safer FIRE-accelerating move; if your loan rate is meaningfully lower (as many older EMI schedules are), continuing to invest usually reaches your FIRE number faster. There's no universally correct answer — it depends on your risk tolerance, loan tenure remaining, and how close you already are to your number.
Why children's goals and health corpus are separate line items
Education, weddings, and healthcare don't inflate at the same rate as everyday living expenses, and they don't land evenly across your timeline — a wedding at your child's age 27 is a single large withdrawal, not a monthly cost. Lumping them into a generic "expenses" multiplier either under- or over-states your real target. This calculator inflates each goal to the specific year it occurs and adds it to your lifestyle corpus separately, so the total FIRE number reflects when money actually leaves the portfolio, not just how much.
Limitations of this calculator
This is a deterministic, single-path projection: it assumes one constant rate of return and one constant inflation rate for the entire period. Real markets don't move in a straight line — a market downturn in the years just before or after retirement (sequence-of-returns risk) can meaningfully change outcomes even if the long-run average return is unchanged. Treat the numbers here as a planning anchor, not a guarantee, and revisit them at least once a year as your expenses, income, and market conditions change.
