Episode 21 – Season One Finale: Bill Bengen on A Richer Retirement and the Future of Safe Withdrawal Rates 

To close out Season One of SMC, Brett and Chris sit down with a true legend in retirement planning — Bill Bengen, the creator of the original 4% rule and author of the new book A Richer Retirement. Bill’s research reshaped how advisors and retirees think about generating income from portfolios. But retirement planning has evolved, and so has his thinking. In this conversation, Brett and Bill go beyond the headline rule of thumb and explore what actually creates a secure, flexible, and meaningful retirement today. They discuss: How Bill’s latest research updates the traditional 4% rule Why asset allocation matters more than most withdrawal debates The role of small-cap stocks in historical retirement success How retirees can adjust spending without sacrificing peace of mind The difference between “not running out of money” and having a truly rich retirement Where advisors and DIY investors often misunderstand safe withdrawal strategies Bill also shares insights from A Richer Retirement about lifestyle design, spending flexibility, and why retirement success is about more than just portfolio math. This episode blends academic research, real-world planning, and practical takeaways — a fitting close to the first season. Contact Bill www.bengenfs.comSend us a question: [email protected]: www.brettcroft.comProduced by 32Q LLC
