The 4% Rule in FIRE — Can You Safely Withdraw 4% Annually from Your Portfolio?

What is the 4% Rule?

The 4% Rule is the foundation of FIRE strategy, stating that you can safely withdraw 4% of your investment portfolio's value annually for 30 years without risk of depleting funds.

Origin of the 4% Rule

The rule comes from the Trinity Study from 1998, which analyzed historical returns of the US stock and bond markets from 1926.

Key assumptions:

• Portfolio: 50-75% stocks, 25-50% bonds
• Withdrawal period: 30 years
• Inflation-adjusted withdrawals
• US market (S&P 500)

How Does the 4% Rule Work in Practice?

Basic Example

• Capital: 1,500,000 PLN
• First withdrawal: 60,000 PLN (4% of 1,500,000)
• Second year: 60,000 × inflation rate (e.g., 61,800 PLN at 3% inflation)
• Subsequent years: Adjust for inflation, regardless of portfolio value

The Mechanism

1. Year 1: Withdraw 4% of initial value
2. Year 2: Withdraw year 1 amount + inflation
3. Market rises: Don't increase withdrawals
4. Market falls: Still withdraw the same amount (inflation-adjusted)

Trinity Study — Historical Results

Success Probability (30 years of withdrawals)

Study Conclusions

• 4% withdrawal rate has 95-98% chance of success
• Higher stock allocation increases probability of success
• 3% withdrawal rate is virtually 100% safe

The 4% Rule in Polish Conditions

Differences for Polish Investors

1. Currency and Inflation

• PLN vs USD: Currency risk with foreign investments
• Polish inflation: Historically higher than US (2-8% vs 2-3%)
• Solution: Investments in currency-hedged ETFs

2. Available Instruments

• WSE: Limited diversification
• Global ETFs: VWRA, IWDA available in PLN
• Treasury bonds: EDO, COI as alternatives

3. Taxation

• Belka tax: 19% on capital gains
• IKE/IKZE: Tax optimization possibilities
• Impact on withdrawals: Must account for taxes in calculations

Alternative Approaches to the 4% Rule

1. The 3.5% Rule

Conservative approach for greater security:

• Success probability: ~100%
• Capital needed: 28.6x annual expenses (vs 25x)
• Example: For 60,000 PLN annually = 1,714,000 PLN

2. Dynamic Withdrawals

Adjusting withdrawals to market conditions:

• Bear market: Reduce withdrawals by 10-20%
• Bull market: Can increase withdrawals
• Advantage: Greater flexibility
• Disadvantage: Variable income

3. Guardrails Strategy

Withdrawal corridor 3-5%:

• Portfolio grows: Increase withdrawals to 5%
• Portfolio declines: Reduce withdrawals to 3%
• Example: Base withdrawal 4%, corridor ±1%

4. Bond Tent

Increasing bond allocation with age:

• 45 years: 70% stocks, 30% bonds
• 55 years: 60% stocks, 40% bonds
• 65 years: 50% stocks, 50% bonds
• Goal: Reducing risk with age

Criticism of the 4% Rule

Main Problems

1. SORR (Sequence of Returns Risk)

• Problem: Early retirement declines are most harmful
• Solution: Higher bond allocation in first years

2. Variable Market Conditions

• Low interest rates: Bonds provide lower returns
• High stock valuations: Potentially lower future returns
• Solution: Review rule in context of current conditions

3. Life Expectancy

• 30 years may not be enough: FIRE at age 40-50
• Solution: Planning for 40-50 years of withdrawals

Practical Application in Poland

Portfolio for 4% Rule in Poland

Basic FIRE Portfolio

• 40% VWRA (Vanguard FTSE All-World) — global stock market
• 25% IWDA (iShares Core MSCI World) — developed markets
• 20% EDO/COI treasury bonds — inflation protection
• 10% REITs/commodities — diversification
• 5% Cash — liquidity for first months

Age-Based Allocation

Financial Freedom Runway and the 4% Rule

Financial Freedom Runway in Freenance shows how many months you can live off current assets:

Runway Formula with 4% Rule:

Runway = (Assets × 0.04 ÷ 12) ÷ Monthly expenses × 12

Interpretation:

• 300+ months: FIRE achieved (can apply 4% rule)
• 200-300 months: Close to FIRE (consider conservative 3.5%)
• < 200 months: Keep building capital

Practical Application Examples

Example 1: Anna, 45 years, 1,800,000 PLN

• Annual withdrawal: 72,000 PLN (4%)
• Monthly expenses: 6,000 PLN
• Portfolio: 70% global ETFs, 30% treasury bonds
• Success probability: ~96%

Example 2: Marek, 40 years, 2,500,000 PLN

• Conservative 3.5%: 87,500 PLN annually
• Monthly expenses: 7,300 PLN
• Portfolio: 75% stocks, 25% bonds
• Success probability: ~99%

Monitoring the 4% Rule

Indicators to Track

1. Portfolio value: How it changes over time
2. Real withdrawal rate: Current withdrawal vs portfolio value
3. Inflation: Adjust withdrawals for inflation
4. Asset allocation: Rebalancing according to plan

When to Modify Strategy

• Withdrawal rate > 6%: Consider reducing expenses
• Withdrawal rate < 2%: Can increase expenses
• Prolonged bear market: Temporarily reduce withdrawals

Summary of the 4% Rule

Advantages:

• Simple to implement
• Historically proven
• Provides spending predictability

Disadvantages:

• Based on past data
• Doesn't account for variable market conditions
• May be too conservative/aggressive

Recommendation for Poland:

• Start with 3.5-4% depending on age
• Use dynamic withdrawals in early years
• Monitor regularly and adjust strategy
