This week, we’re replaying one episode that stood out in particular as Wade’s favorite conversation of the year, based on both the discussion and the questions it sparked from listeners. We’ll be back with brand new episodes after the holiday break. Thanks for listening this year, and we look forward to continuing the conversation in 2026. Repost from Episode 195 In this episode of Retire with Style, Wade Pfau and Alex Murguia talk with William Bengen, pioneer of the 4% rule in retirement planning. They explore the rule’s evolution, how inflation and market valuations shape sustainable withdrawals, and Bengen’s current recommendations. The discussion highlights the role of asset allocation, the importance of withdrawal strategies, and why ongoing monitoring is essential for a secure retirement. Takeaways William Bengen modernized retirement income planning with the 4% rule. Inflation is a critical factor in determining sustainable withdrawal rates. Market volatility can significantly impact retirement portfolios. A comprehensive withdrawal plan should consider multiple factors. Current recommendations suggest a withdrawal rate of around 5.5%. Asset allocation plays a vital role in retirement planning. Investors should consider a rising equity glide path strategy. Regular monitoring and adjustments to retirement plans are essential. High inflation can permanently elevate withdrawal amounts. The 4% rule is not a one-size-fits-all solution.
