You Could Spend WAY More Than the 4% Rule Suggests (Says the Man Who Created It)

Financial planning’s most famous guideline just got an upgrade. In this exclusive interview, James speaks with Bill Bengen—the MIT-trained engineer turned financial advisor who created the 4% rule—about his updated research and what it means for retirees today. Bengen reveals that diversification alone can raise the safe withdrawal rate to 4.7%, and under certain market conditions, retirees may be able to withdraw 6%, 7%, or even 8% annually. The original 4% rule was never meant to reflect average scenarios. It was built from the worst-case retirement timing in modern history. Even then, a 4% withdrawal strategy lasted 30 years. Bengen’s findings show that across history, the average sustainable withdrawal rate has exceeded 7%, suggesting many retirees could be living more cautiously than necessary. In this conversation, James and Bengen discuss the two factors that matter most when determining safe withdrawals: inflation expectations and stock market valuations at retirement. They also explore why downturns don’t usually require major changes to a plan, but inflation threats demand immediate attention. Rather than focusing on a single “magic number,” Bengen emphasizes a process-oriented approach—one that starts with your circumstances and considers the economic environment before setting a withdrawal strategy. - Advisory services are offered through Root Financial Partners, LLC, an SEC-registered investment adviser.
