Strategy Comparison

💡 What This Tool Does

The Strategy Comparison tool compares different retirement withdrawal strategies to help compare which approach ranks highest in the model for the scenario. It analyzes strategies like the 4% rule, dynamic withdrawal, and guardrails to show which shows the strongest modeled outcomes for the portfolio.

Key Questions It Answers:

• Which withdrawal strategy ranks highest in the model for the portfolio?
• How much can be safely withdrawn each year in the model?
• Which strategy provides the strongest modeled balance of income and safety?
• How do different strategies perform in market downturns?

📋 How to Use This Tool

Before Starting

Have modeled retirement plan data ready:

• Retirement account balances
• Expected retirement expenses
• Social Security and other income
• Desired withdrawal amount

Step-by-Step Instructions

1. Select Strategies to Compare: Choose 2-4 withdrawal strategies
2. Set Parameters: Initial withdrawal rate, adjustments, guardrails
3. Run Comparison: Analyze how each strategy performs
4. Review Results: Compare success rates, income levels, ending balances
5. Choose Preferred Strategy: Select based on stated priorities

🔍 What to Look For

Key Metrics

1. Success Rate: Percentage of scenarios where strategy succeeds
   • 85%+ is generally considered good
   • Higher is better, but may mean lower income
2. Average Annual Income: How much the model indicates can be withdrawn on average
3. Ending Balance: Portfolio value at end of retirement
4. Worst Case Scenario: Performance in market downturns

📊 How to Interpret Results

Understanding the Output

The comparison shows how different withdrawal strategies perform for the specific modeled portfolio and goals.

Next Steps

1. Select strategy with 85%+ success rate
2. Review annually and adjust as needed
3. Run Monte Carlo to verify robustness
4. Consider combining strategies

🎓 Advanced Withdrawal Strategies

The 4% Rule Origins

Based on William Bengen's 1994 research, the 4% rule worked historically but may be too aggressive or conservative depending on current market valuations.

Dynamic Spending Rules

Adjust withdrawals based on portfolio performance and age. Spend more in good years, less in down years, maintaining portfolio longevity while maximizing lifestyle.

Guardrails Approach

Set upper and lower spending limits. If portfolio performs well, increase spending. If it declines, reduce spending. This balances enjoyment with safety.

❓ Frequently Asked Questions

Q1: Is the 4% rule still safe?

It's a good starting point but may be too aggressive with today's low interest rates and high stock valuations. Consider 3.5% for more safety or dynamic strategies.

Q2: What's the preferred withdrawal strategy?

Dynamic strategies that adjust spending based on portfolio performance typically maximize both longevity and lifestyle in the model. The preferred option depends on flexibility and risk tolerance.

Q3: Should I adjust withdrawals for inflation every year?

Not necessarily. Dynamic strategies suggest increasing only when portfolio performs well, keeping real spending roughly constant but not rigidly inflation-adjusted.

Q4: What if I need more than 4% early in retirement?

Consider a "smile" spending pattern - higher early (active years), lower mid-retirement, potentially higher late (healthcare). Front-load spending if healthy and active.

Q5: How do I choose between strategies?

Fixed strategies (4% rule) are simple. Dynamic strategies provide more flexibility but require active management. Choose based on comfort level with adjusting spending.
