Confused concerning the 4% retirement rule? Uncover why specialists like Bengen maintain altering the protected withdrawal price—and why 3.5% could also be safer in India.
Retirement planning usually boils down to 1 sensible fear: “How a lot can I safely withdraw from my nest egg annually so the cash lasts so long as I do?”
The reply individuals hunt for is a single quantity: the Secure Withdrawal Fee (SWR). Probably the most well-known of them is the 4% Rule, born from William Bengen’s analysis within the Nineties. However over three many years Bengen has refined his view a number of instances — and people modifications matter. This text explains why Bengen modified his suggestions, the assumptions behind his numbers, why the U.S. findings don’t map neatly to India, and why — for many Indians — 3%–3.5% (and as little as realistically potential) is the safer zone.
Secure Withdrawal Fee India: Is 3.5% Higher Than the 4% Rule?

What precisely is a Secure Withdrawal Fee (SWR)? — Easy language
SWR solutions a sensible query: from a retirement corpus, how a lot can you’re taking out within the first yr, then enhance that quantity yearly to match inflation, and nonetheless anticipate the cash to final (for a set horizon like 30 years)?
Instance (easy): retire with Rs.1 crore.
- A 4% SWR means withdraw Rs.4,00,000 in yr one. In yr two, enhance the rupee quantity by the inflation price (to maintain buying energy). Repeat annually. The SWR is “protected” if, traditionally, that plan survived for the retirement horizon being examined.
Two issues to recollect:
- SWR is an estimate based mostly on historic knowledge and particular portfolio assumptions.
- It’s not a assure — it depends upon future returns, inflation, and the way lengthy you reside.
Refer my earlier publish on SWP and the way it’s really misguided on this monetary world “Systematic Withdrawal Plan SWP – Harmful idea of Mutual Funds“
William Bengen — the place the 4% got here from (and the info behind it)
In 1994 William Bengen analysed long-run U.S. historic returns (shares and bonds again to 1926). He examined many beginning years and withdrawal charges for a 30-year retirement horizon. His headline consequence: 4% (first-year withdrawal, then inflation changes) would have survived virtually all historic 30-year retirements within the U.S.
Essential particulars which might be usually missed:
- Portfolio assumed: Bengen’s exams assumed a balanced portfolio — roughly 50–75% in U.S. equities (primarily large-cap shares) and 25–50% in intermediate-term authorities bonds. The 4% consequence depends upon staying invested on this combine and never panic-selling after crashes.
- Worst beginning yr: one of many hardest historic begin years was 1966, which produced a most sustainable price round 4.15% in Bengen’s backtests. He rounded right down to 4% as a conservative, easy-to-remember rule.
- Not a regulation: Bengen’s consequence was empirical — “it survived in historic knowledge” — not a common mathematical reality.
How and why Bengen revised his suggestions over time
Bengen didn’t proclaim “4% without end” and cease. As markets modified and he ran new exams, he up to date his findings. Summarised:
Interval / Analysis Part | Portfolio Assumption | Bengen’s steered SWR (approx) | Why he modified |
1994 (authentic) | 50–75% US equities + bonds | 4.0% | Historic worst-case (e.g., retirement beginning 1966) survivals led to 4% as conservative spherical quantity. |
Late Nineties–2000s | Add U.S. small-cap publicity | 4.5%–4.7% | Small caps traditionally improved long-term returns and survival charges in backtests. |
2010s | Similar belongings, however a lot decrease bond yields & increased fairness valuations | ~3.5%–4.0% | Decrease anticipated future returns (low bond yields, costly shares) decreased the sustainable withdrawal estimates. |
2020s (current) | Emphasis on adaptability | No single fastened % | Bengen started arguing for versatile withdrawals — spend extra in good markets and reduce in unhealthy markets. |
So his “altering” isn’t flip-flopping for enjoyable — it displays totally different inputs (asset combine, valuations, bond yields) and trendy warning about decrease future returns.
The “versatile withdrawals” drawback — concept vs. retiree psychology
In current interviews Bengen has emphasised a versatile method: increase withdrawals when markets are robust, reduce when markets are weak. Academically it’s wise — it preserves capital and reacts to actuality.
However for retirees this raises actual issues:
- Predictability issues greater than optimization. Retirees want a gentle, dependable revenue to budgeting and planning life. Telling them “reduce spending if markets fall” is straightforward on paper however painful in observe — you can not simply shrink medical care, a dependent’s schooling, or recurring commitments as a result of markets fell.
- Behavioral danger: Many retirees panic-sell in bear markets. A method that requires frequent changes will increase the prospect of emotionally pushed errors.
- Practicality: Month-to-month payments, EMIs, care prices — households want revenue predictability.
So whereas versatile withdrawals are a sound instrument, they should be used fastidiously — not because the default method for retirees who worth stability.
Sequence of Returns Danger — the silent hazard everybody misses
Sequence of returns danger means the order of funding returns issues if you find yourself withdrawing cash. Two portfolios with similar common returns can behave very in a different way for a retiree, relying on whether or not the unhealthy years arrive early or late.
Illustration (easy simulation, similar common returns however totally different order):
Assumptions for illustration:
- Corpus: Rs.1,00,00,000 (Rs.1 crore)
- Preliminary withdrawal: 4% = Rs.4,00,000 annually (for simplicity, we maintain withdrawals fixed right here to focus on the order impact — this isolates sequence danger)
- Common return goal throughout the 10-year window: 6% per yr.
We assemble two 10-year return sequences with the similar common (6%):
- Good-first: large optimistic returns within the early years, modest thereafter.
- Unhealthy-first: the identical returns however in reverse order (large negatives early, large positives later).
Key balances after withdrawals (chosen years):
Yr | Good-first steadiness (Rs.) | Unhealthy-first steadiness (Rs.) |
1 | 1,21,00,000 | 96,00,000 |
2 | 1,35,14,999 | 92,00,000 |
5 | 1,48,33,519.75 | 81,68,000 |
10 | 1,31,30,190.15 | 1,11,96,650.48 |
Interpretation:
- With good returns early you construct a buffer; the portfolio grows even when you withdraw.
- With unhealthy returns early you shrink the bottom and could also be pressured to chop withdrawals or promote when costs are low. Even when later years are good, the early injury can depart you emotionally and financially worse off.
Lesson: If a portfolio faces extreme unfavourable returns early in retirement, withdrawals can do everlasting injury. Sequence danger is likely one of the essential causes to be conservative early in retirement.
Labored instance: Rs.1 crore corpus, 6% inflation — 4% vs 3.5% withdrawal
Actual retiree concern: how large is the distinction between 4% and three.5%? Even a half-percent sounds small, nevertheless it compounds.
Assumptions:
- Corpus = Rs.1,00,00,000 (Rs.1 crore)
- Inflation = 6% yearly
- Two withdrawal guidelines: 4% and 3.5% (first-year withdrawal quantities; annually the rupee withdrawal will increase by 6% to maintain up with inflation)
Preliminary withdrawals (yr 1):
- 4% – Rs.4,00,000
- 3.5% – Rs.3,50,000
Inflation-adjusted withdrawals (chosen years):
We compute withdrawal in yr n as preliminary withdrawal × (1.06)^(n?1).
Yr | 4% path (Rs.) | 3.5% path (Rs.) |
1 | 4,00,000 | 3,50,000 |
10 | 6,75,792 | 5,91,318 |
20 | 12,10,240 | 10,58,960 |
30 | 21,67,355 | 18,96,436 |
(Instance calculations: Yr 10 withdrawal at 6% inflation means multiply preliminary withdrawal by 1.06^9. For 4%: 4,00,000 × 1.06^9 ? Rs.6,75,792.)
Cumulative nominal withdrawals over 30 years (sum of every yr’s withdrawal):
- 4% path – Rs.3,16,23,274 (~Rs.3.16 crore)
- 3.5% path – Rs.2,76,70,365 (~Rs.2.77 crore)
Distinction over 30 years: ~Rs.39.53 lakh (? Rs.39,52,909)
What this reveals: that modest preliminary conservatism (0.5% much less withdrawal) yields a considerably decrease drawdown on the corpus over many years, giving higher probability of survival and suppleness towards unhealthy returns, higher-than-expected healthcare prices, or longevity surprises.
Monte Carlo Simulation: Testing 3%, 3.5%, and 4% Withdrawal Charges in India
Relating to retirement planning, guidelines of thumb just like the 4% rule could be helpful however usually don’t replicate Indian realities. To see how protected totally different withdrawal charges are for Indian retirees, I ran a Monte Carlo Simulation.
What’s Monte Carlo Simulation?
It’s a way the place we run 1000’s of “what if” situations with totally different mixtures of inventory and bond returns. As an alternative of assuming the market grows easily, it captures volatility — the ups and downs that retirees really face.
Assumptions Used
- Portfolio: 50% Nifty 50 TRI (fairness) + 50% 10-Yr Authorities Securities (G-sec)
- Nifty 50 anticipated return: 10% per yr, volatility: 18%
- G-sec anticipated return: 7.5% per yr, volatility: 3%
- Correlation between fairness and debt: -0.2 (mildly unfavourable)
- Inflation: 6% per yr
- Retirement horizon: 30 years
- Preliminary corpus: Rs.1 crore
- Withdrawal examined: 3%, 3.5%, and 4% of preliminary corpus (inflation-adjusted yearly)
- Simulations: 10,000 random paths
Outcomes at a Look
SWR | tenth Yr Median Corpus | twentieth Yr Median Corpus | thirtieth Yr Median Corpus | 30-Yr Survival Chance |
3.0% | Rs.1.68 Cr | Rs.2.74 Cr | Rs.4.25 Cr | 96.5% |
3.5% | Rs.1.58 Cr | Rs.2.36 Cr | Rs.3.09 Cr | 89.9% |
4.0% | Rs.1.49 Cr | Rs.1.97 Cr | Rs.1.95 Cr | 77.7% |
The takeaway: Decrease withdrawal charges not solely enhance security but additionally depart behind a a lot bigger legacy corpus.
Chart 1 – Median Corpus Progress Over 30 Years

Interpretation:
At 3% withdrawal, the corpus grows steadily and infrequently faces depletion. At 4%, the median corpus stagnates, exhibiting a lot increased danger of operating out of cash.
Chart 2 – Chance of Corpus Survival (30 Years)

Interpretation:
At a 3% withdrawal, the portfolio lasts for 30 years in virtually 97% of circumstances. At 4%, it drops to 78%. This distinction is large and reveals why “4% rule” could also be too dangerous within the Indian context.
Why This Issues for Indian Retirees
- Volatility tolerance: Western retirees usually maintain 60–75% in fairness even in retirement. In India, most are uncomfortable with that danger, so warning is required.
- Sequence of returns danger: If a nasty inventory market hits in your early retirement years, increased withdrawals (like 4%) can destroy the corpus.
- Safer zone: For Indian retirees, 3% to three.5% withdrawal appears a lot safer and sensible. In the event you can stay with even much less, that’s the very best insurance coverage towards uncertainty.
Disclaimer – The Monte Carlo outcomes introduced above are based mostly on historic return assumptions of Nifty 50 TRI and 10-year Authorities Securities. Precise future returns could differ considerably on account of market cycles, rate of interest actions, inflation, and financial situations. These charts present possibilities, not ensures. Buyers ought to deal with this solely as an academic illustration and never as personalised monetary recommendation. At all times evaluate your withdrawal technique recurrently and alter based mostly in your precise portfolio efficiency and spending wants.
Why the U.S. 4% rule is hard for India (an in depth look)
- Larger long-term inflation in India
U.S. historic inflation is ~2–3% (for a lot of many years). India’s long-term common has been increased — usually ~5–6% or extra. Larger inflation will increase future spending wants shortly, that means withdrawals develop sooner in rupee phrases. - Totally different debt market & yields
Bengen’s exams included long-term U.S. authorities bonds with lengthy, regular histories. India’s debt market construction, tax guidelines, and yields are totally different. Predictable long-term “protected” returns like long-duration treasuries are a weaker assumption right here. - Fairness tradition and behavioral consolation
Bengen’s 4% assumptions require holding 50–75% fairness even throughout retirement. Many Western retirees are extra comfy with equities as a result of they’ve lengthy, multigenerational expertise with public markets. Indian retirees are usually newer to fairness investing — a 50–75% fairness posture throughout retirement after which seeing a 30% market decline is emotionally brutal. Folks usually promote on the worst time. - Longevity
Indians, particularly in city areas, live longer. A retirement horizon of 30 years could also be too quick — extra may have 35–40 years of sustainability.
These elements make the 4% rule unreliable as a direct transplant into Indian retirement planning.
Sensible, detailed recommendation for Indian retirees (the way to translate this into motion)
- Goal a conservative SWR: 3%–3.5%
- 3% in order for you most security and may settle for decrease spending initially.
- 3.5% in order for you a center path — cheap spending now with higher odds of lasting.
- 4% must be used solely in case you are comfy with excessive fairness publicity and with the emotional stress of volatility.
- Use the bucket technique (detailed):
- Bucket 1 (0–7/10 years): money + short-duration debt + liquid devices — sufficient to fund near-term withdrawals. This removes the necessity to promote equities in a down market.
- Bucket 2 (subsequent 10–15 years): mix of debt and average fairness (25–40%) — goal for some progress whereas preserving capital.
- Bucket 3 (long run): increased fairness (40–50%) for progress to fight longevity and inflation. Transfer cash into nearer-term buckets on a deliberate schedule.
- Maintain assured revenue the place potential
- A small portion invested in annuities or a pension-like product should buy sleep — a hard and fast flooring to fulfill important bills. Even small assured revenue reduces sequence danger and permits equities to do their job.
- Plan for well being inflation individually
- Medical prices usually rise sooner than CPI. Maintain a separate well being corpus or ensure medical insurance is strong.
- Select an fairness allocation you’ll be able to emotionally stay with
- In the event you can’t deal with 50–75% fairness, don’t pressure your self for theoretical increased SWR. The advantage of a decrease fairness allocation is peace of thoughts; the price is probably going a decrease sustainable withdrawal price — so cut back SWR accordingly.
- Keep away from knee-jerk reactions on market swings
- Persist with the plan — but when markets crash and your withdrawals threaten long-term sustainability, cut back discretionary spending (holidays, downscaling luxuries) relatively than pressured promoting of progress belongings.
- Evaluation each 2–3 years (not each day)
- Verify the plan, not the each day NAV. Use multi-year opinions to make measured changes.
- Look ahead to charges and taxes
- Excessive fund charges and taxes compound the issue. Use low-cost funds and tax-efficient withdrawal sequencing (tax-exempt vs taxable buckets).
Backside line — the straightforward sentence to recollect
William Bengen gave us a vastly helpful rule of thumb — however even he modified it as markets and knowledge modified. He proved the technique (check traditionally, look at asset mixes), not a single everlasting quantity. For many Indian retirees: goal for a withdrawal price within the 3%–3.5% vary, maintain fairness publicity at a degree you’ll be able to emotionally deal with, use buckets and a few assured revenue, and be conservative early in retirement as a result of sequence danger is actual.
And at all times keep in mind: decrease withdrawal = extra peace of thoughts.
