How to use this retirement calculator
This retirement calculator projects your FIRE (Financial Independence, Retire Early) corpus target specifically for Indian inflation and market conditions. Five inputs drive the result:
- Current age & target retirement age— the horizon over which your investments will compound. The retirement calculator works for any age from 22 to 70.
- Current monthly expenses — what your household spends today (groceries, rent / EMI, utilities, discretionary). This is inflated forward by India’s 6-6.5% long-run CPI to compute retirement-age expense.
- Current investments — EPF balance, PPF, equity MF, FDs, and any other liquid wealth. The retirement calculator projects this forward at your expected return rate.
- Existing monthly SIP — what you currently invest each month across equity, debt, hybrid funds. Combined with the lump-sum above, this is your current trajectory.
- Safe Withdrawal Rate (SWR) — 3-3.5% conservative for India (vs US’s 4%), 4% global default. The retirement calculator defaults to 3.3% (≈ 30× annual expenses) as the India-margin-of-safety baseline.
The retirement calculator shows your required corpus at retirement, projected corpus at current pace, the gap, and the additional monthly SIP needed to close that gap. Every input auto-saves to the URL — share with a CA, spouse, or bookmark for quarterly reviews.
How the FIRE / retirement calculator works
FIRE stands for Financial Independence, Retire Early — the idea that you accumulate enough invested wealth to fund your lifestyle for the rest of your life without further employment. The maths is simple in principle: take today’s expenses, inflate them to your retirement date, and divide by a safe annual withdrawal rate to find the corpus you need. The work is in honest assumptions: how long you’ll live, how fast prices will rise, what your portfolio will earn, and how much you can sustainably draw down without running out.
The core formula
Required corpus = Annual expense at retirement ÷ SWR
With a 4% safe withdrawal rate (SWR), required corpus = annual expense × 25. With 3% SWR, it’s × 33. The expense at retirement is your current expense compounded at inflation for the years until you retire:
Annual expense at retirement = Today's annual expense × (1 + inflation)years to retire
For ₹75,000/month today (₹9 lakh/year), 25 years to retirement at 6% inflation: annual expense at retirement = ₹9L × 1.0625 ≈ ₹38.6 lakh. Required corpus at 4% SWR = ₹9.66 crore.
The 4% safe withdrawal rate
The 4% rule comes from the 1998 “Trinity Study” (Bengen et al), which back-tested US portfolios from 1926 onward and found that a 60/40 stock/bond portfolio could sustain a 4%-of-initial- corpus withdrawal, inflated annually, for 30 years with very high success probability. The rule has held up across most subsequent market cycles in the US.
For India, the 4% rule deserves caution:
- India’s long-run inflation (6-7%) has been higher than the US (~3%), making sustained real withdrawals harder.
- Indian sequence-of-returns risk is higher because the equity market is more volatile.
- Indian fixed income (debt MFs / bonds) yields are nominally higher but real yields after tax have been modest.
Many Indian FIRE practitioners aim for 3% to 3.5% SWR (× 28 to × 33 multiplier) to give themselves headroom. The calculator’s SWR field defaults to 4% but lets you toggle to 3% for a more conservative target.
Inflation assumptions
India’s long-run CPI averages 6-7%. Healthcare inflation consistently runs higher (~8%), which matters in retirement when medical costs become a larger share of expense. Education inflation is similarly high at ~10% if you’re funding child education before retiring.
The calculator uses a single inflation rate. For a more sophisticated plan, run it twice: once with 6% (general expenses) and once with 8% (healthcare-heavy retirement) and choose between the two outputs as the conservative target.
Pre-retirement returns — what to assume
For long-horizon (15+ years) equity-heavy portfolios, the historical Indian record suggests:
- Pure equity / index funds — 11–14% nominal over 15+ year rolling windows.
- Aggressive hybrid (75% equity, 25% debt) — 10–12%.
- Balanced (50/50) — 8–10%.
- Conservative (75% debt, 25% equity) — 7–8%.
Default 12% in the calculator reflects an equity-heavy long-horizon portfolio. Adjust down if your asset allocation is more conservative.
Worked example — ₹75K monthly expense, age 35 to 60
Today’s annual expense ₹9 lakh, 25-year horizon, 6% inflation, 12% pre-retirement return, 4% SWR:
- Annual expense at retirement = ₹9L × 1.0625 = ₹38.6L
- Required corpus = ₹38.6L ÷ 4% = ₹9.66 crore
- Existing corpus ₹0, ₹50K SIP @ 12% for 25 years → ~₹9.5 cr
- Gap = ₹16 lakh (small; close to on-track)
- Additional SIP needed: ₹830/month (top-up)
Same scenario starting at age 50 instead of 35:
- 10-year horizon, ₹50K SIP → only ~₹1.16 cr accumulated.
- Required corpus ₹1.61 cr (less inflation runway).
- Gap ₹45 lakh; additional ₹19,400/month SIP needed.
The lesson: the difference between starting at 35 vs 50 is roughly a 20× compounding multiplier. Time in the market is the most precious variable in any FIRE plan.
What the calculator does NOT account for
- Pension / EPF / NPS — if you have an employer pension or expect EPS payouts, subtract that monthly income from your retirement expense to size the corpus down.
- One-time large expenses — child marriage, home purchase, parent care — budget these as add-ons.
- Healthcare insurance — covered by adequate health insurance, not by the corpus.
- Government health benefits — minimal in India; do NOT factor in.
- Sequence-of-returns risk — the order of returns matters; bad returns early in retirement permanently impair the corpus. The 4% rule survives this in back-tests but gives no margin. A 3-3.5% SWR provides one.
- Longevity beyond 90 — default life expectancy is 90; bump to 95 or 100 for a stress test.
Strategies for closing a gap
- Save more — the additional-SIP figure above is the deterministic answer. Adjust your monthly outgo or ramp savings via annual step-up.
- Retire later — each extra year of accumulation at 12% adds roughly 10-12% to the corpus AND reduces the required corpus (fewer years of expense to cover).
- Lower your retirement expense — downsize home, move to a lower cost-of-living city, eliminate discretionary spend. Each ₹10K/month reduction lowers the required corpus by ₹30 lakh at 4% SWR.
- Earn more / take on additional risk — higher equity allocation, longer SIP horizon, possibly side income. Beware: this strategy substitutes return assumptions for cash savings, which is a less reliable lever.
FIRE variants
- Lean FIRE — minimalist lifestyle (₹30-40K/mo retirement expense). Requires ₹1-1.5 cr corpus.
- Regular FIRE — comfortable middle-class lifestyle (₹75K-1L/mo). Requires ₹3-5 cr.
- Fat FIRE — affluent lifestyle (₹2L+/mo). Requires ₹6-10 cr+.
- Coast FIRE — reach a corpus that, if left to compound until traditional retirement age, will grow to the full required corpus. You can then “coast” with minimal new contributions.
- Barista FIRE — reach a corpus large enough to cover most expenses, with a part-time job covering the rest. More flexibility than full FIRE.
Frequently asked questions
- Is the 4% rule guaranteed for India?
- No rule is guaranteed. The 4% rule has 95% historical success in US back-tests for 30-year retirements. Indian data is shorter and more volatile; many advisors recommend 3% to 3.5% for safety. Use the SWR slider to compare both.
- Should I include EPF / PF in my corpus?
- Yes. EPF + PPF + NPS Tier 1 + mutual fund holdings + any other invested wealth all count as your “current corpus.” Real estate is debatable: count it only if you intend to sell at retirement.
- How does the calculator handle taxes?
- Returns shown are pre-tax. Most withdrawals from MFs in retirement are LTCG (12.5% above ₹1.25L exemption) or slab rate for debt; for SWR-based planning, this is small enough to fold into the conservative SWR. For precision, plan for an extra 0.5 to 1% tax drag.
- How accurate is this calculator?
- All maths uses high-precision decimal arithmetic and 800+ property-based assertions verify the invariants. The numbers are only as good as your assumptions on inflation, returns, and longevity — review them annually.

FIRE variants — leanFIRE, fatFIRE, baristaFIRE, coastFIRE (India numbers)
The global FIRE community distinguishes four common flavours. Here are the India-specific corpus targets for each, assuming a 30-year retirement horizon and the conservative 3.3% SWR (30× annual expenses) that is more defensible for Indian inflation + equity behaviour than the 4% / 25× benchmark inherited from US studies.
FIRE variants with India-specific monthly expense bands and corpus targets at 3.3% SWR (30× multiplier)| Variant | Monthly spend | Annual spend | Corpus at 3.3% SWR | Who it suits |
|---|
| leanFIRE | ₹40,000 | ₹4.8 L | ₹1.44 Cr | Tier-2 city, minimal lifestyle, no dependants |
| regular FIRE | ₹80,000 | ₹9.6 L | ₹2.88 Cr | Metro, middle-class household, 1–2 kids grown |
| fatFIRE | ₹2,00,000 | ₹24 L | ₹7.2 Cr | Metro, international travel, premium healthcare |
| baristaFIRE | ₹60,000 (₹30K from corpus) | ₹7.2 L (₹3.6 L from corpus) | ₹1.08 Cr (plus ~₹30K/mo part-time work) | Retire from primary job, keep low-stress part-time income |
| coastFIRE | ₹80,000 (future) | ₹9.6 L (future) | ~₹90 L at 35, grow to ₹2.88 Cr by 60 | Save enough young, then pause SIPs while compounding catches up |
These are nominal, present-day expense-level targets — before you layer inflation to your retirement year. For a 35-year-old targeting regular FIRE at 55, inflate ₹2.88 Cr at 6.5% for 20 years → ₹10.13 Cr as the nominal target on the day you retire. The calculator above does this math automatically.
Worked examples — retirement calculator for common India profiles
Example A — 28-year-old fresher targeting FIRE at 50
- Current age 28, FIRE age 50 (22-year horizon)
- Current monthly expense ₹50,000 → annual ₹6 L
- Inflation 6.5% → at age 50: ₹23.7 L annual expense
- Target corpus at 3.3% SWR: ₹23.7 L × 30 = ₹7.12 Cr
- Current portfolio ₹5 L, existing SIP ₹25,000/month at 12% expected
- Projected corpus at 50 (current ₹5 L + ₹25K SIP × 22 yrs at 12%): ~₹3.58 Cr
- Gap: ₹7.12 Cr − ₹3.58 Cr = ₹3.54 Cr shortfall
- Required additional SIP to close gap: ~₹25,000/month (total SIP ~₹50K/mo)
Interpretation: 50% savings rate at ₹1 L take-home is achievable for a fresher without dependants living in a tier-2 city. For metro-living, either accept FIRE at 55 instead of 50, or target leanFIRE (₹40K expense) first.
Example B — 40-year-old starting late, targeting 60
- Current age 40, retirement age 60 (20-year horizon)
- Current monthly expense ₹1 L → annual ₹12 L
- Inflation 6.5% → at 60: ₹42.3 L annual expense
- Target corpus at 4% SWR: ₹42.3 L × 25 = ₹10.58 Cr
- Current portfolio ₹30 L (PPF ₹15 L, equity MF ₹15 L), SIP ₹40K/month
- EPF expected at 60 (assuming ₹25K/mo employer + employee contribution compounding at 8.25%): ~₹1.68 Cr
- Projected equity corpus at 60 (₹15 L + ₹40K × 20 yrs at 12%): ~₹4.45 Cr + ₹45 L PPF = ₹4.9 Cr liquid
- Total projected: ₹4.9 Cr + ₹1.68 Cr EPF = ₹6.58 Cr
- Gap: ₹10.58 Cr − ₹6.58 Cr = ₹4 Cr shortfall
- Options: bump SIP to ₹90K, delay retirement by 3 years, or target a leaner expense band (₹70K → ₹9.96 Cr target which is closer to projected).
Starting late is the single most expensive mistake in retirement planning. The compounding runway is irreplaceable. See our SIP vs lumpsum guide on deploying any late-career bonuses or windfalls directly.
Example C — Self-employed, high earner, 38 targeting FIRE at 45
- Current age 38, FIRE age 45 (7-year horizon)
- Current monthly expense ₹1.5 L → annual ₹18 L (metro + kids in private school)
- Inflation 7% → at 45: ₹28.9 L annual expense
- Target corpus at 3% SWR (aggressive safety): ₹28.9 L × 33 =₹9.54 Cr
- Current portfolio ₹2 Cr (equity ₹1.5 Cr, debt ₹50 L), SIP ₹1 L/month
- Projected corpus at 45 (₹2 Cr + ₹1 L × 7 yrs at 11% blended): ~₹5.39 Cr
- Gap: ₹4.15 Cr shortfall in 7 years
- Requires ~₹2.5 L/month SIP + any lumpsum deployments to close — tight but doable for a ₹5 L+ take-home
India glide-path: equity allocation by age
Too conservative too early — inflation erodes real value. Too aggressive at retirement — sequence-of-returns risk can permanently wreck the corpus if the first 5–10 years of withdrawals coincide with a bear market. A rule-of-thumb glide path that works for Indian taxpayers (factoring PPF ceiling, EPF auto-accrual, and 80C incentives) is:
Recommended equity / debt / cash allocation by age bracket for an Indian FIRE portfolio| Age | Equity % | Debt % | Cash / liquid % | Notes |
|---|
| 25–35 | 80–90 | 10–20 | 2–3 | Max equity; PPF + ELSS fill debt |
| 35–45 | 70–80 | 20–30 | 3–5 | Start layering debt; EPF accrual helps |
| 45–55 | 55–70 | 30–45 | 5 | De-risk; add government / SDL debt funds |
| 55–60 | 45–55 | 40–50 | 5–10 | Pre-retirement bridge; lock SCSS on turning 60 |
| 60+ (retired) | 30–45 | 45–60 | 10 | Bucket strategy: 3-yr cash + 5-yr debt + long-term equity |
Sequence-of-returns risk — the silent corpus killer
The single biggest threat to a retired corpus is not average return; it is the order of returns. A 30-year retirement that starts with two bad equity years can run out of money even if the long-run average returns are great. The maths: you withdraw inflation-adjusted rupees from a corpus that shrank by 30% in year 1 — you cannot recover from that hole even if year 5 onward delivers stellar returns.
Mitigations for Indian FIREers:
- 3-year cash bucket. Keep 3× annual expenses in liquid funds + sweep-FD at retirement start. If equity crashes in year 1, withdraw from cash, not equity. See our emergency fund calculator for sizing the liquid tier.
- Dynamic SWR. Instead of rigid 4% / inflation-adjusted withdrawals, reduce withdrawals by 10% in years when the portfolio is down 15%+. This is the Guyton-Klinger guardrails approach; it materially reduces ruin risk.
- Delay SCSS / annuity to 70. If you can defer these to later, they cover the “late-in-retirement” years when sequence risk has mostly played out. Early years come from portfolio; later years from guaranteed income.
- Part-time income (baristaFIRE). Even ₹20K/month of consulting or passive income during the first 5 years of retirement dramatically extends corpus longevity.
Taxation of retirement withdrawals (FY 2026-27)
How your corpus is taxed when you withdraw varies by instrument. Plan the drawdown order to minimise the tax drag.
- Equity MF. Each year’s redemption = LTCG event. ₹1.25 L annual exemption is automatic; gains above that taxed at 12.5% flat under Section 112A. See our LTCG calculator for per-year drawdown modelling.
- Debt MF post-April-2023. Slab rate at redemption (Section 50AA). For a retiree with total income in ₹3–7 L band under new regime, effective drag is 0–15%. Debt fund laddering + staggered redemption is usually better than the tax-equivalent FD ladder.
- EPF. Fully tax-exempt on withdrawal if 5+ years of continuous service. 80C benefit already claimed in contribution years, no further tax. The companion Employees’ Pension Scheme 1995 provides a small slab-taxable pension. See our EPF calculator.
- PPF. Fully exempt (EEE) on maturity at year 15 (or extended in 5-year blocks) under Section 80C. Premature withdrawal rules vary; keep as the tax-free bedrock of the retirement corpus.
- NPS Tier-1. 60% lumpsum at 60 tax-free, 40% mandatory annuity per PFRDA exit regulations — annuity income fully taxable at slab. See NPS calculator.
- Senior Citizen Savings Scheme (SCSS). Interest fully taxable at slab. 80TTB gives seniors a ₹50,000 deduction on total interest income. Auto-applied in ITR.

Worked example — 35-year-old planning retirement at 60
A concrete, end-to-end walkthrough of the retirement corpus calculator using realistic India assumptions. Plug your own numbers into the calculator above to reproduce this for your situation.
Worked example — 35-year-old retirement plan with 7% inflation, 12% pre-retirement return, 7% post-retirement return, life expectancy 85| Input | Value |
|---|
| Current age | 35 |
| Retirement age | 60 |
| Life expectancy | 85 (25-year retirement) |
| Current monthly expense | ₹75,000 (₹9 lakh/year) |
| Inflation assumption | 7% per year |
| Pre-retirement return | 12% (equity-heavy SIP) |
| Post-retirement return | 7% (debt-heavy bucket) |
| Current corpus | ₹15 lakh (across equity MF + PPF + EPF) |
Step 1 — Inflate the expense. ₹9 lakh today at 7% inflation for 25 years → annual expense at 60 ≈ ₹48.85 lakh (₹4.07 lakh/month). This is what life will cost on day 1 of retirement.
Step 2 — Apply the corpus multiplier. With a 25-year retirement horizon at 7% post-retirement return vs 7% inflation (real return ≈ 0%), you need approximately 25-30× the annual expense. Using a conservative 27× multiplier (the India-realistic equivalent of 3.7% SWR): ₹48.85 L × 27 = ₹13.19 Cr nominal corpus target at age 60.
Step 3 — Project current corpus forward. ₹15 lakh compounded at 12% for 25 years → ~₹2.55 Cr at retirement.
Step 4 — Compute the SIP gap. Shortfall = ₹13.19 Cr − ₹2.55 Cr = ₹10.64 Cr. Back-solving the SIP formula at 12% over 25 years for a ₹10.64 Cr future value gives a required monthly SIP of approximately ₹56,500/month.
Step 5 — Reality check. ₹56,500 SIP is roughly 75% of the current monthly expense. For a household earning ₹1.5-2 lakh net-of-tax, this is achievable but tight. Options to ease the SIP burden: (a) step-up the SIP 8-10% per year as income grows (a step-up SIP starting at ₹35K and growing 10% annually meets the same target), (b) accept retirement at 62 instead of 60, which compounds two more years and cuts the required SIP by ~₹12K, or (c) target a leaner monthly expense of ₹60K today instead of ₹75K (drops the corpus to ~₹10.55 Cr and the SIP to ~₹45K).
NPS vs PPF vs equity mutual fund for retirement — which to pick?
The three pillars of long-horizon Indian retirement saving have very different lock-in, tax, and return profiles. The right answer is almost always “use all three”, but the allocation between them depends on age, tax slab, and how much flexibility you want post-60. Comparison table:
NPS Tier-1 vs PPF vs equity mutual fund — lock-in, return, tax treatment, and withdrawal flexibility for retirement planning in India| Parameter | NPS Tier-1 | PPF | Equity Mutual Fund |
|---|
| Lock-in | Until age 60 (75 max) | 15 years (extendable in 5-yr blocks) | None (open-ended; ELSS has 3-yr lock) |
| Expected return (long run) | ~9-10% (active choice equity 75%) | 7.1% (FY 2026-27 admin rate) | ~11-12% nominal (index / flexi-cap) |
| Contribution cap per year | No cap; tax break capped at ₹50K (80CCD(1B)) + 80C limit | ₹1.5 lakh/year | No cap |
| Tax on contribution | Deductible u/s 80CCD(1B) + 80C | Deductible u/s 80C | ELSS deductible u/s 80C; regular MF: no deduction |
| Tax on growth | Tax-deferred | Tax-free (EEE) | Tax-deferred until redemption |
| Tax on withdrawal | 60% lumpsum tax-free; 40% mandatory annuity taxable at slab | Fully tax-free | LTCG 12.5% above ₹1.25 L/year exemption |
| Withdrawal flexibility | Very low — locked till 60, then 40% annuity-locked | Low — partial after year 5, full at maturity | Very high — redeem any business day |
| Best for | Extra ₹50K tax break, disciplined long-horizon corpus | Tax-free debt bedrock, parking emergency-style funds | Core compounding engine, post-60 flexibility |
Typical allocation for a 30-something planner: Max out PPF (₹1.5 L/year) for the tax-free debt bedrock, contribute ₹50K/year to NPS Tier-1 for the extra 80CCD(1B) deduction, and route the remaining monthly savings into equity mutual funds via SIP. This combines the tax advantage of all three buckets while preserving post-60 flexibility through the MF portion. Use our NPS calculator, PPF calculator, and SIP calculator to size each stream precisely.
Sequence-of-returns risk — why the first 5 years matter most
The sequence of returns problem is the most counter-intuitive and under-discussed risk in retirement planning. Two retirees with the same average annual return over 30 years can have completely different outcomes — one ends with millions, the other runs out of money — purely based on whether the bad return years come early or late.
Why the early years are uniquely dangerous. When you start drawing down a retired corpus, every rupee you withdraw during a bear market is a rupee that can never compound back. If the portfolio drops 30% in year 1 and you still withdraw 4%, you have crystallised a permanent loss on that withdrawal slice. Over a 30-year retirement, the first 5 years of returns explain 60-70% of the variance in terminal corpus outcomes. The last 5 years explain almost none — because by then the corpus has either survived or it has not.
Concrete example. A ₹3 cr corpus, 4% withdrawal (₹12 L/year inflation-adjusted), 8% average return over 30 years. If the 8% comes evenly distributed, the corpus ends at ₹4 cr. If the first three years deliver −20%, −10%, −5% (followed by 27 years averaging ~11% to maintain the same 30-year average), the corpus is exhausted by year 22. Same average return, very different outcome.
Practical mitigations for Indian retirees.
- Bucket strategy. Hold 3 years of expenses in cash and liquid funds, plus 5-7 years in debt funds and SCSS (post-60). Equity stays untouched in bear years; withdrawals come from cash and debt while the equity portion has time to recover. Bucket refilling happens in good years only.
- Dynamic / guardrail withdrawals. Skip the inflation adjustment in years where the portfolio fell more than 10%. This Guyton-Klinger style rule preserves capital during bad sequences and lifts success rates from ~85% (rigid 4% rule) to ~98% (4% + guardrails) over 30 years.
- Delay the equity drawdown. Live entirely off EPF + PPF maturity + SCSS interest + NPS lumpsum during the first 5-7 years of retirement. Let equity compound through potentially bad early years. This is the single most effective sequence-risk hedge for Indian retirees because we already have multiple tax-advantaged fixed-income vehicles that mature near 60.
- Part-time income. Even ₹20-30K/month of consulting, teaching, or board fees during the first 5 years of retirement removes the need to withdraw from any equity slice during a bad sequence. baristaFIRE is mathematically the strongest variant for someone retiring at 55-58.
How much money do I need to retire in India?
The short answer is 25-30× your annual expenses at retirement, but the long answer depends on city, lifestyle, healthcare coverage, and dependants. A ballpark by lifestyle (in today’s rupees, before inflation adjustment to your retirement year):
- leanFIRE — ₹40K/month expense → ₹1.44 Cr corpus needed (today’s rupees). Suits debt-free tier-2 city home, minimal lifestyle, no dependants.
- regular FIRE — ₹75-80K/month expense → ₹2.7- ₹2.9 Cr (today’s rupees). Suits a metro middle-class household with kids who are independent, own home, decent healthcare coverage.
- fatFIRE — ₹2 L/month expense → ₹7.2 Cr (today’s rupees). Suits metro premium lifestyle, regular international travel, private healthcare provisioning.
Now inflate to retirement year. A regular-FIRE ₹2.88 Cr today becomes about ₹11-12 Cr if you’re retiring in 22-25 years at 6.5-7% inflation. The calculator at the top of this page handles the inflation math automatically when you enter your current age and retirement age.
What is the 25× rule for retirement?
The 25× rule (also called the “rule of 25”) says your retirement corpus needs to be 25 times your annual expenses at the year of retirement. It comes from the Trinity Study (Cooley, Hubbard & Walz, Trinity University working paper, 1998), which found that withdrawing 4% of your starting corpus in year 1 — and inflation-adjusting each subsequent year — gave a 95%+ probability of the corpus lasting 30 years. 25 = 1 ÷ 0.04, so the multiplier is just the inverse of the safe withdrawal rate.
For India we recommend bumping the multiplier to 30-33× because (a) Indian inflation is roughly 2× higher than the US baseline the rule was tested on, (b) Indian retirement horizons are stretching past 30 years as life expectancy grows, and (c) sequence-of-returns risk is elevated in an emerging market. A 30× multiplier corresponds to a 3.33% withdrawal rate; a 33× multiplier corresponds to ~3%.
Is ₹1 crore enough for retirement in India?
For most people retiring in the next 5-15 years, ₹1 crore is not enough. At the India-safe 3.3% withdrawal rate, ₹1 cr supports about ₹27,500/month of inflation-adjusted expenses. That covers a leanFIRE lifestyle in a tier-2 city — but only if you (a) already own a debt-free home, (b) have negligible healthcare risk thanks to family or employer-retiree coverage, and (c) keep monthly expenses below ₹30K.
For a metro household with ₹60K-1 L monthly expense at the year of retirement, the corpus needed is ₹2.2-3.6 cr at the same SWR. ₹1 cr is meaningful as a milestone but should be treated as the first checkpoint, not the destination.
How is retirement corpus calculated?
The retirement corpus calculation is a 4-step process: (1) inflate today’s annual expense to the retirement year using your inflation assumption, (2) multiply by the SWR multiplier (25× for the US 4% rule, 30-33× for India-safe 3-3.3%), (3) compound your current investments forward to the retirement year at expected returns, (4) back-solve the SIP needed to fill any shortfall. The calculator at the top of this page runs all four steps using the inflation, return, and horizon inputs you provide.
Should I invest in NPS or mutual funds for retirement?
Use both. NPS Tier-1 provides an extra ₹50K deduction under Section 80CCD(1B) that is unavailable through mutual funds — that is worth ~₹15K of real tax savings per year at the 30% slab. But NPS locks 40% into a mandatory annuity at 60 and the annuity income is taxed at slab — a meaningful drag for high-bracket retirees. Mutual funds give you full drawdown flexibility and a flat 12.5% LTCG tax above the ₹1.25 L annual exemption per Section 112A.
Practical allocation: contribute exactly ₹50,000/year to NPS Tier-1 (to capture the bonus deduction under Section 80CCD(1B)), and route every additional rupee into equity index funds + ELSS via SIP. ELSS captures the 80C limit (NPS within 80C is governed by Section 80CCD(1)); the rest flows into regular index / flexi-cap funds for unrestricted flexibility. See the NPS calculator and SIP calculator for sizing.
