At a time when the financial community provided inconsistent retirement advice, the 4% withdrawal rate was a data-backed strategy that revolutionized retirement planning. Today we speak with William Bengen, a literal rocket scientist and the influential personal advisor who popularised the 4% withdrawal rate, A.K.A, the 4% rule. After exploring what the 4% rule entails and the impact that it had on the financial industry, we talk about updates that William has made to his theory since first publishing about it in 1994. We then unpack more of the rule, talking about its conservative nature, whether young retirees should adhere to it, and if there are situations where you should break the rule. Reflecting on criticisms of the 4% rule, we ask William about how it fits with the notion of dynamic spending. His answers highlight his approach in helping his clients to maintain the same lifestyle that they have when they enter retirement. Later, we touch on tips to keep track of your expenses, whether you should taper your retirement income, the role of bonds and small-cap stocks in your portfolio, and William’s view that financial planning should be fee and not commission-based. We wrap up by discussing William’s career and how he defines success for himself.
