Retirement withdrawal planning is the most critical phase of financial planning — getting it wrong means running out of money. William Bengen's 4% rule has guided retirees since 1994, but modern research suggests adjustments may be needed. With the average retirement lasting 20-30 years and healthcare costs rising 5-7% annually, sustainable withdrawal strategies are more important than ever.

Key Takeaways
- • Annual Withdrawal = Portfolio × Withdrawal Rate. 4% rule: $1M × 4% = $40K/year, inflation-adjusted.
- • Portfolio longevity: simulate year-by-year with withdrawals + inflation adjustment vs. returns.
- • Sequence of returns risk: poor early years devastate outcomes. Bucket strategy mitigates this.
- • RMDs from traditional IRAs/401(k)s start at age 73 (SECURE 2.0). Roth IRAs have no RMDs.

How Does Retirement Withdrawal Work?
Annual Withdrawal Formula
Annual Withdrawal = Portfolio × Withdrawal Rate. 4% rule: $1M × 4% = $40K first year, then adjust for inflation each year.
Portfolio Longevity Simulation
Year-by-year: portfolio grows by expected return, shrinks by withdrawal. Withdrawal increases by inflation annually. Run until portfolio exhausted or horizon reached.
4% Rule Origin
William Bengen (1994) found 4% of initial portfolio, inflation-adjusted, historically lasted 30 years in US markets. Trinity Study (1998) confirmed with 50/50 portfolio.

Frequently Asked Questions
What is the 4% rule?
William Bengen's 1994 research found that withdrawing 4% of initial portfolio (adjusted for inflation) historically lasted 30 years. A $1M portfolio = $40K/year first year, then inflation-adjusted.
Is the 4% rule still valid?
It was based on historical US returns. With lower expected returns, many advisors now suggest 3-3.5%. The Trinity Study confirmed 4% has a ~95% success rate over 30 years with a 50/50 stock/bond portfolio.
What is sequence of returns risk?
Poor returns in early retirement years are devastating. A -20% loss year 1 followed by recovery is much worse than the reverse. This is the biggest risk retirees face.
How do I adjust withdrawals for inflation?
Increase your withdrawal amount by inflation rate annually. Year 1: $40K. Year 2 at 3% inflation: $41,200. Year 10: $52,272. This maintains purchasing power but increases portfolio strain.
What is the bucket strategy?
Divide portfolio into 3 buckets: 1-2 years cash (spending), 3-7 years bonds (stability), 8+ years stocks (growth). Draw from cash bucket, replenish from bonds/stocks periodically.
When must I take Required Minimum Distributions?
RMDs from traditional IRAs and 401(k)s start at age 73 (SECURE 2.0 Act). Based on life expectancy tables. Roth IRAs have no RMDs. Penalty for missing: 25% of the amount not withdrawn.
