The 4% Rule in Switzerland: How Much Can You Really Withdraw?
The "4% rule" is the most famous rule of thumb in retirement planning. With a starting capital of CHF 500'000, you can withdraw CHF 20'000 in the first year — and the money will last 30 years. It sounds that simple. Except: the rule comes from the USA. From a different market reality, with different taxes, different life expectancy, and different social security. In Swiss financial forums, it's still quoted as universal truth. This article corrects that. We show you where the 4% rule comes from, in which 5 fundamental points Swiss reality differs, and what your realistic Swiss withdrawal rate looks like — with a concrete example and three alternative withdrawal strategies.

Where the 4% rule comes from — Bengen and the Trinity Study
In 1994, American financial advisor William Bengen published a study in the Journal of Financial Planning. His question: how much can a retiree safely withdraw from a stock-bond portfolio without the money running out in their lifetime? Bengen tested every 30-year window from 1926 to 1976 with historical US market data. His answer: 4% of starting capital in the first year, then inflation-adjusted annually — and the money lasted in every 30-year window tested.
In 1998, three professors from Trinity University verified the calculations with expanded data. The "Trinity Study" confirmed: with a 50/50 or 60/40 stock-bond portfolio, capital survived in 95%+ of historical 30-year windows with a 4% withdrawal rate. The study has been updated several times, most recently in 2011 with data through 2009 — the conclusion remained stable.
So the "4% rule" was born: simple, robust, widely quoted. The FIRE movement (Financial Independence, Retire Early) adopted it as the gold standard. From a US rule of thumb, it became the global standard measure for retirement wealth.
The mathematical idea behind it: with a long-term real portfolio return of about 5-6% per year (nominal 7-8%, minus 2-3% inflation) and a 4% withdrawal, the substance lasts statistically almost certainly 30 years — usually much longer. In about 50% of historical windows, wealth actually grew during the decumulation phase.
The 5 reasons it doesn't work 1:1 in Switzerland
The Trinity Study is based on US data — and Swiss reality differs in five important points. Some speak for a lower withdrawal rate, others for a higher one. The net result makes it a stand-alone Swiss calculation.
Difference 1
AHV as reliable pension foundation
Swiss AHV pays a real public pension of up to CHF 30'240 annually for individuals, CHF 45'360 for couples (as of December 2026 incl. 13th AHV payment). US Social Security is much more variable and long-term politically uncertain. For Swiss retirees, this means: a large part of basic costs is already covered, securities wealth doesn't have to do everything. This security allows tendentially higher equity allocations and withdrawals from the wealth portion — you can calculate less risk-averse.
Difference 2
Lower historical inflation
Average Swiss inflation was around 0.8% per year from 1995-2024. US inflation in the same period was around 2.5%. This difference significantly affects nominal adjustment of withdrawals. At a 4% starting withdrawal of CHF 20'000, 2% inflation requires CHF 29'700 after 20 years. At 1% Swiss inflation, only CHF 24'400. Lower inflation relieves your portfolio — you need less wealth for the same lifestyle.
Difference 3
Higher life expectancy
Swiss people have one of the highest life expectancies worldwide by far. A 65-year-old Swiss woman statistically lives another 22 years, a man 20 years. Wealth must therefore last not 30, but rather 25-35 years. Anyone retiring at 65 and living to 90 needs a more conservative withdrawal rate. The classic Trinity Study tests 30 years — for longer horizons, the "safe" rate drops to 3.5% or 3.2%.
Difference 4
Tax-free capital gains for private individuals
Swiss private investors pay no capital gains tax on realised securities gains. In the USA, long-term capital gains are taxed at 15-20%. This fundamentally changes the withdrawal mathematics: a US retiree must give about 15% of every realised gain to tax — a Swiss keeps 100%. Effectively, a Swiss can run a lower gross rate with the same net withdrawal — or, conversely, have more net spending at the same gross rate.
Difference 5
CHF appreciation and Swiss equity market
The Swiss franc has appreciated in real terms against USD, EUR, and GBP over the last 30 years. This makes imported goods (cars, electronics, travel) cheaper — the effective purchasing power of Swiss pensions slowly grows relative to abroad. Additionally, the Swiss equity market (SMI) is historically more defensive than the S&P 500 — lower volatility, higher dividend yield, dominated by quality companies like Nestlé, Roche, Novartis. This alone doesn't change the 4% rule, but it makes a globally diversified portfolio with a Swiss component less volatile than a pure US portfolio.
The realistic Swiss withdrawal rate
When you cleanly calculate the 5 Swiss specifics, the following range emerges:
| Profile | Recommended withdrawal rate | Reasoning |
|---|---|---|
| Retirement at 65, life expectancy 85-90, wealth to be preserved | 3.0-3.3% | Conservative, inheritance-oriented |
| Retirement at 65, life expectancy 85, wealth can be consumed | 3.5-4.0% | Classic Swiss Trinity adaptation |
| Retirement at 60-62 (early retirement), 30+ years horizon | 3.0-3.5% | Longer decumulation phase |
| FIRE at 45-50, 40+ years horizon | 2.8-3.2% | Very long decumulation, before AHV |
| Late retirement at 70, short horizon | 4.5-5.0% | Shorter decumulation, higher withdrawal tolerable |
The rule of thumb "3.5% in Switzerland" is a good middle ground for most retirees between 60 and 65. Those wanting to bequeath wealth go more toward 3.0%. Those wanting to consume it while healthy can go to 4%.
The Swiss advantage: the lower withdrawal rate initially sounds like sacrifice. But it's more than compensated by the reliable AHV base. A US retiree with CHF 500'000 must finance their entire living from it. A Swiss retiree with the same wealth has additional CHF 25-45'000 AHV. Effectively, they have more available income at a lower wealth withdrawal.
Worked example: Mrs Meier with CHF 500'000
Mrs Meier is 65, just retired. She has:
- AHV pension: CHF 27'000/year (just below maximum)
- PK pension (remainder after 50% lump sum): CHF 12'000/year
- Wealth from PK withdrawal + free savings: CHF 500'000
- Residence: Zürich, condominium fully amortised
- Living costs gross: CHF 60'000/year
Guaranteed income from AHV + PK: CHF 39'000. Gap from wealth: CHF 21'000/year. On CHF 500'000 wealth, that's a 4.2% withdrawal rate. Slightly above the classic Swiss 3.5% recommendation — but not panic-inducing.
Classic Trinity-style calculation
4.2% withdrawal, 60% equities / 40% bonds, 1% inflation, 5% return
Mrs Meier withdraws CHF 21'000 inflation-adjusted each year, then CHF 21'210, CHF 21'422, etc. At a net real return of 4%, her capital grows slightly anyway.
Wealth at 75: ~CHF 510'000 (real ~CHF 460'000)
Wealth at 85: ~CHF 510'000 (real ~CHF 415'000)
Lasts until: 95+ — substantial inheritance balance
Stress test: Weak start
What if markets stagnate in the first 5 years?
Imagine the first 5 years after retirement bring 0% return (market phases like 2000-2005). Mrs Meier still withdraws CHF 21'000 per year.
Wealth after 5 years: ~CHF 395'000 (CHF 105'000 less)
Then normal 4% returns over 20 years. Final wealth at 90: ~CHF 380'000.
Still sufficient — but the buffer for the last 5 years gets tight. Here is sequence-of-returns risk in practice.
Conservative variant with 3.5%
Mrs Meier reduces withdrawal to 3.5% (CHF 17'500/year)
Gap not 100% covered from wealth — Mrs Meier adjusts lifestyle slightly (CHF 56'500 instead of CHF 60'000 gross).
Wealth at 85: ~CHF 580'000 (real ~CHF 470'000)
Lasts until: 100+ — high inheritance reserve
This variant offers psychological security: even during a severe market crisis, Mrs Meier doesn't have to anxiously cut withdrawals.

Open the calculator →Sequence-of-returns risk — the underestimated killer
Sequence-of-returns risk describes a mathematically elegant but psychologically uncomfortable effect: the order of returns in the first 5-10 retirement years is disproportionately important. Even if your average return over 30 years is 5% — what matters is whether you had the bad years at the beginning or the end.
| Scenario | Average return | Final wealth after 30 years |
|---|---|---|
| Steady 5% every year | 5% | CHF 1.05M |
| First 5 years -5%, then 7% | 5% | CHF 380'000 (-64%!) |
| First 5 years +12%, then 4% | 5% | CHF 1.50M (+43%) |
Three scenarios, same average return, three very different outcomes. The reason: withdrawals from a falling portfolio are irreversible. Anyone withdrawing CHF 20'000 in a crash year has withdrawn a larger percentage than thought — and cannot make up the loss later, because the money is already gone.
Three protection strategies
- Liquidity buffer in the first 5 years: hold 2-3 annual withdrawals in cash/money market. During market decline, withdraw from there, not from the equity portion.
- More defensive allocation just before and after retirement: reduce equity allocation in the 2 years before and 5 years after retirement (60% instead of 70%).
- Dynamic withdrawal ("guardrails"): reduce withdrawal by 10-20% for 1-2 years after a market decline of >20%. This gives the portfolio time to recover.
Practical consequence: the "static" 4% rule is an approximation. In reality, retirees should be flexible — more frugal in bad markets, more generous in good ones. This effectively increases the sustainable withdrawal rate by 0.3-0.5 percentage points. Those who are flexible can therefore confidently try 4% instead of 3.5%.
Three alternatives to the rigid 4% rule
Alternative 1 — Variable Percentage Withdrawal
Instead of a fixed franc amount each year, you withdraw a fixed percentage of current wealth — e.g. 4% per year. With good markets, withdrawal grows automatically; with bad ones, it shrinks.
- Advantage: capital never runs out, mathematically impossible
- Disadvantage: uncertain annual income, difficult for planning
- Suitable for: retirees with flexible lifestyle and AHV/PK base security
Alternative 2 — Bucket Strategy
Wealth is split into 3 "buckets":
- Bucket 1 (cash): 2-3 annual withdrawals, immediately available
- Bucket 2 (bonds): another 5-7 annual withdrawals, medium-term
- Bucket 3 (equities): rest, long-term 10+ year horizon
Withdrawals always from Bucket 1. When equities run well, Bucket 1 is refilled from Bucket 3. During market decline, from Bucket 2.
- Advantage: psychologically robust — you don't panic-watch the equity bucket
- Disadvantage: slightly more administrative effort, small performance hit from higher cash quote
- Suitable for: most Swiss retirees — the emotionally most robust variant
Alternative 3 — Floor-and-Upside
You establish a "floor" (safe minimum income) and invest the rest with growth focus.
- Floor: AHV + PK pension + possibly annuity → guaranteed basic income
- Upside: securities portfolio with higher equity allocation — withdrawals vary by market phase
- Advantage: security for basic needs, growth for comfort/inheritance
- Disadvantage: annuities can be expensive, floor strategy requires planning
- Suitable for: retirees with high security need and existing pension structure
Special case: FIRE in Switzerland
The FIRE movement (Financial Independence, Retire Early) takes the 4% rule directly from the USA — problematic in Swiss application. Three reasons:
- Longer decumulation phase: someone retiring at 50 plans 40+ years of consumption. The 4% rule was validated for 30 years. At 40+ years, the "safe" rate drops to 3.0-3.3%.
- No AHV before 65: in Switzerland, AHV pension begins at earliest 63 (early withdrawal) or 65. Before that, all income must come from wealth — no crutch like US Social Security from 62.
- Health insurance burden: those who stop working early continue paying health insurance — in Switzerland fixed at about CHF 4-6'000 per year per person, regardless of income. That eats significantly into the FIRE budget.
Realistic Swiss FIRE mathematics:
| FIRE age | Recommended withdrawal rate | Wealth for CHF 50'000/year |
|---|---|---|
| 45 (40+ years horizon) | 2.8-3.0% | CHF 1.67-1.79M |
| 50 (35+ years horizon) | 3.0-3.3% | CHF 1.50-1.67M |
| 55 (30+ years horizon) | 3.3-3.6% | CHF 1.39-1.50M |
| 60 (25+ years horizon) | 3.5-4.0% | CHF 1.25-1.43M |

Checklist: Find your own withdrawal rate
Step 1: Base inventory
- Expected AHV pension (updated account statement)
- PK pension at chosen withdrawal mode (annuity/lump sum/mixed)
- Other income (rentals, royalties, part-time job)
- Total "guaranteed" annual income
Step 2: Estimate living costs
- Actual living costs of the last 3 years (from account statement, minus savings)
- Disappearing costs (commute, work clothing, BVG contributions)
- New costs (more leisure, travel, health)
- Target living costs after retirement
Step 3: Calculate gap
- Target living minus guaranteed income = wealth withdrawal
- Wealth withdrawal / wealth = withdrawal rate
- Below 3.5%? → comfortable
- 3.5-4.5%? → borderline, dynamic strategy required
- Above 4.5%? → adjust living costs or work longer
Step 4: Stress tests
- What if markets drop -20% in the first 5 years?
- What if inflation is 4% for 5 years?
- What if care costs hit from age 80 (CHF 80-150k/year)?
- Review semi-annually: does reality still match the plan?
The central insight: The 4% rule is a useful rule of thumb, but not natural law. For Swiss retirees, the sustainable withdrawal rate is closer to 3.5% — compensated by the reliable AHV base. Those flexible enough to withdraw less in bad market years can move closer to 4%. Those wanting to bequeath wealth or aiming for FIRE retirement at 50 should stay closer to 3%. More important than the exact percentage is the flexibility of the strategy and protection against sequence-of-returns risk in the first 5 years.

Explore arvy →Frequently asked questions
What is the 4% rule?
A US retirement rule of thumb from 1994 (Bengen) and 1998 (Trinity Study). Withdraw 4% of starting capital in year 1, then continue inflation-adjusted — historically the money lasted in every 30-year window with a 50/50 portfolio.
Does the 4% rule work in Switzerland?
Not 1:1. Swiss reality is different: stronger AHV base, lower inflation, higher life expectancy, tax-free capital gains, CHF appreciation. Realistic is 3.5% — but available AHV income compensates.
How much can I really withdraw as a Swiss retiree?
3-4% of starting capital depending on profile. CHF 500'000 → CHF 15-20'000/year in addition to AHV/PK. Preserve wealth: 3%. Consume at good living standard: 4%. FIRE with 40+ years: 2.8-3.0%.
What is sequence-of-returns risk?
The first 5-10 years after retirement are disproportionately important. Bad returns at the start can irreversibly damage wealth — withdrawals from a falling portfolio aren't recoverable. Protection: liquidity buffer, more defensive allocation, dynamic withdrawal.
What alternatives to the 4% rule exist?
Three: Dynamic withdrawal (percentage instead of franc amount), bucket strategy (cash/bonds/equities buckets), floor-and-upside (pension floor plus growth portfolio). Bucket strategy psychologically most robust for most.
How does AHV affect my withdrawal rate?
CHF 30'240 maximum single pension, CHF 45'360 couple (from 12/2026 incl. 13th AHV). Covers basic costs for many retirees. Wealth only needs to cover the "gap" plus comfort → lower required withdrawal rate than in the USA.
Is the 4% rule usable for FIRE in Switzerland?
Too optimistic — FIRE decumulation phase 40-50 years instead of 30. Realistic 2.8-3.3%. But: hurdle absolutely lower because AHV starts at 65. For CHF 30'000/year from 50, you need about CHF 1M wealth.
What happens to my withdrawal during high inflation?
4% rule provides inflation-adjusted increase. CH inflation historically low (~1%), relieves portfolio. High inflation hits pensions harder than securities — equities are best long-term inflation hedge.
