Retirement & FIRE PlannerFIRE
Most retirement calculators answer the easy question — what will my SIP be worth? This one answers the hard one: how much do you actually need, and when do you cross the line where work becomes optional? It computes your FIRE number from inflation-adjusted expenses, finds the age your corpus first covers a full retirement, and stress-tests whether the money lasts to life expectancy.
Highlights
- FIRE number built from a real drawdown to life expectancy, not just a 25× shortcut.
- Financial independence age: the year your corpus first overtakes the target.
- Coast, Lean and Fat FIRE milestones alongside the standard number.
- Exact monthly SIP required to close the gap, solved rather than guessed.
- Year-by-year drawdown showing whether the corpus survives — or the age it runs dry.

What FIRE actually means, and the four flavours worth knowing
Financial Independence, Retire Early is less about quitting work than about reaching the point where work is a choice. The mechanism is simple: accumulate enough invested capital that its returns cover your living costs indefinitely. The difficulty is entirely in the numbers.
The community has settled on a few variants, and they are genuinely different plans rather than marketing labels.
- Regular FIRE: a corpus that funds your current lifestyle indefinitely.
- Lean FIRE: the same idea at roughly 75% of your expenses — reachable years earlier, with less margin.
- Fat FIRE: around double your expenses, for those who want the option of a materially better lifestyle.
- Coast FIRE: enough invested today that, with no further contributions, compounding alone carries you to your target by your retirement age. You still need income for living costs, but you can stop saving.
Why the 4% rule needs adjusting for India
The 4% safe withdrawal rate — and its shorthand, the 25× rule — comes from US research on a 30-year retirement funded by US stocks and bonds. It is a useful anchor, and this calculator shows it as a cross-check, but importing it unmodified into an Indian plan is optimistic for two reasons.
First, Indian inflation has historically run higher than the 2-3% those studies assume, and 6-7% inflation compounds brutally over decades. Second, FIRE by definition means a longer retirement: someone retiring at 45 with a life expectancy of 85 needs the corpus to survive 40 years, not 30. The failure rate at 4% rises materially as the horizon lengthens.
This is why the headline number here comes from an explicit year-by-year drawdown to your life expectancy rather than a fixed multiple. Many Indian FIRE planners work with 3-3.5% instead of 4%, which translates to needing 28-33× expenses rather than 25×.
Inflation is the variable that decides everything
At 6% inflation, costs double roughly every twelve years. Monthly expenses of ₹60,000 today become about ₹1.7 lakh in twenty years and ₹3.4 lakh in thirty. Planning against today's expenses is the most common and most expensive mistake in retirement planning.
What matters is the real return — your nominal return minus inflation. A 12% return against 6% inflation is a real return of about 5.7%, not 6%. Over thirty years that difference alone moves the required corpus significantly, which is why this calculator reports real returns explicitly.
Note also that retirement does not stop inflation. Your withdrawals must keep rising through a thirty or forty year retirement, which is exactly what the drawdown schedule models.
Where EPF and NPS fit in a FIRE plan
EPF at 8.25% tax-free is an excellent debt allocation and a poor FIRE vehicle, for one structural reason: you cannot access it freely before retirement. NPS is worse on this count, locking money until 60 with only partial withdrawal permitted, and mandating an annuity for a portion at exit.
For a plan that targets independence at 45 or 50, this creates a sequencing problem. Your EPF and NPS balances are real wealth and belong in your corpus, but they are not available during the years between early retirement and 60. Many Indian FIRE plans therefore run two buckets: accessible investments to bridge from early retirement to 60, and locked retirement accounts that take over afterwards.
If you include EPF and NPS in the current corpus above, sense-check that the accessible portion alone can cover the bridge years.
The three levers, in order of power
Your savings rate dominates everything else. It cuts the target and raises the contribution simultaneously — spending less both shrinks the corpus you need and grows the corpus you build. Nothing else in the model does both at once.
Time is the second lever, and it works on its own once compounding takes hold. The third is return, which gets the most attention and deserves the least: chasing an extra 2% adds risk you may not be able to hold through a bad decade, and it does nothing to the target.
Try it above. Raising your SIP by 20% will almost always pull your financial independence age in further than raising your assumed return by two percentage points.
Methodology
- Current expenses are scaled by your retirement expense ratio, then inflated to the retirement date.
- The FIRE number is the present value at retirement of inflation-linked annual withdrawals to life expectancy, taken at the start of each year.
- A safe-withdrawal-rate figure is shown alongside as a familiar cross-check — at 4% this is the 25× rule.
- Accumulation compounds monthly with an annual SIP step-up; the required SIP is solved from the linearity of future value.
- Financial independence age is found by recomputing the target every year as expenses inflate and comparing it to the corpus.
Scope and assumptions
- Returns are assumed steady each year; real markets are not, so treat the corpus as a planning midpoint.
- Taxes on withdrawals are not modelled, and neither are lump sums such as property sales or inheritance.
- Include EPF and NPS balances in your current corpus if you are counting them toward retirement.
- A retirement longer than 40 years makes sequence-of-returns risk more important than the average return.
FAQ
How much money do I need to retire in India?
Work backwards from expenses, not from a round number. Take your current monthly spending, adjust it for how retirement changes it, inflate it to your retirement date, and find the corpus that funds inflation-linked withdrawals for the rest of your life. For someone spending ₹60,000 a month today and retiring in 30 years, that typically lands in the ₹8-12 crore range in future rupees — which sounds alarming until you remember those are heavily inflated rupees.
What is my FIRE number?
The corpus at which investment returns cover your living expenses indefinitely. The quick version is 25× annual expenses, from the 4% withdrawal rule. This calculator computes it more carefully, as the present value of every inflation-adjusted withdrawal from retirement to life expectancy, and shows the 25× figure alongside for comparison.
Is the 4% rule safe for India?
Treat it as an upper bound rather than a target. It was derived from US market history over 30-year retirements with lower inflation than India has experienced. For a FIRE plan spanning 40 years or more at 6-7% inflation, many Indian planners use 3-3.5% instead, which means needing roughly 28-33× expenses rather than 25×.
What is Coast FIRE and have I reached it?
Coast FIRE is the amount invested today that will grow into your full FIRE number by your target retirement age with no further contributions. Once you hit it you still need to earn enough to live on, but you can stop saving for retirement entirely. The calculator shows your Coast FIRE number and flags whether your current corpus already clears it.
What is the difference between Lean FIRE and Fat FIRE?
Lean FIRE funds a deliberately modest lifestyle, around 75% of typical expenses, and is reachable years earlier with correspondingly less margin for error. Fat FIRE targets roughly double, for people who want the option of significantly more comfort. Both are shown as milestones so you can see how the timeline shifts.
How do I calculate the SIP needed for retirement?
Project what your existing corpus grows to by retirement, subtract that from your target, and solve for the monthly contribution that fills the gap. Because future value is linear in the contribution amount, this has an exact answer rather than needing trial and error — the calculator reports the required monthly SIP and how much more it is than you are investing now.
Should I include EPF and NPS in my retirement corpus?
Yes, if you are counting them toward retirement, but note the access constraint. Neither is freely available before retirement age, and NPS locks funds until 60 with a mandatory annuity at exit. If you are targeting independence at 45 or 50, check that your accessible investments alone can bridge the years until those accounts open up.
What is a step-up SIP and why does it matter so much?
A step-up SIP increases your monthly investment by a fixed percentage each year, usually tracking salary growth. The compounding effect is large: a ₹30,000 SIP growing 10% a year contributes dramatically more over 30 years than a flat ₹30,000. If your income rises and your SIP does not, inflation quietly erodes your real savings rate.
What inflation rate should I assume for India?
6-7% is the common planning range. Headline CPI has often been lower, but personal inflation for the things retirees actually buy — healthcare, education, domestic help, services — has run higher. Healthcare inflation in particular is frequently in double digits, which matters because it becomes a larger share of spending later in retirement.
How long will my retirement corpus last?
That depends on the withdrawal rate, the return, and inflation. The drawdown schedule above runs your projected corpus year by year through retirement, growing withdrawals with inflation, and reports either that the corpus survives to your life expectancy or the exact age it runs out. If it runs out, raising the SIP or delaying retirement are the two reliable fixes.
What is sequence-of-returns risk?
The risk that a market crash lands in the first few years of retirement, when you are withdrawing from a full corpus. The same average return with poor early years can exhaust a portfolio that would otherwise have lasted decades. It is why retirees hold two to three years of expenses in liquid, low-volatility assets, and why a 40-year retirement warrants a lower withdrawal rate than a 25-year one.
Can I retire early in India at 45?
It is achievable but demands a savings rate most people find uncomfortable — frequently 50-60% of income — and a corpus large enough to fund a retirement of 40 years or more. Set your retirement age to 45 above and look at the required SIP. If it is unrealistic, the levers are spending less, earning more, or moving the date. Spending less is the most powerful, because it lowers the target and lifts the contribution at the same time.
