#377: Today’s episode is sheer retirement nerd bliss. We talk to the creator of the 4 percent retirement safe withdrawal rule, Bill Bengen. If you’re new to retirement planning, you might not yet grasp the gravity of this. Let’s cut to the chase: the 4 percent rule is one of the most revolutionary, groundbreaking insights in the field of retirement research in the past 30 years. To understand why, let’s climb in our time machines and return to 1994. Back then, many financial advisors were telling their clients that they could safely withdraw 7 percent of their retirement portfolio each year. After all, the simplistic logic went, the stock market has historically yielded between 7 to 9 percent returns, so that type of withdrawal rate shouldn’t dwindle the principle … right? ⠀ Bill Bengen, an MIT graduate and former rocket scientist, decided to build a better model. He looked at the performance of investment portfolios across 30-year time horizons, beginning in 1926. Under the assumption that the portfolio is invested 50 percent in an S&P 500 Index and 50 percent in intermediate-term bonds, in a tax deferred account, he found that retirees could only withdraw 4.2 percent of their portfolio in the first year of retirement, and that amount adjusted for inflation each subsequent year. He called this the “safe withdrawal rate” that gave people a reasonable chance of not outliving their money, based on historic performance. He published the results in the Journal of Financial Planning and caused a stir. This was revolutionary. It upended the assumptions that dominated the field at the time. And it remains a cornerstone of retirement planning to this day. We talk to Bill Bengen about his discovery – and his latest research – in today’s episode.

#375: Here’s the deal: The majority of people who write about personal finance repeat the same tired aphorisms and cliches. “Millennials aren’t investing enough,” they’ll lament. “Millennials are amassing wealth at a slower pace than previous generations!” But when you ask for their source, they turn up blank. Each writer points to a headline, which sources another headline, in a neverending circular secondary-source-citation that fails to point to any primary data source. Nick Maggiulli doesn’t play that game. If you haven’t heard the name Nick Maggiulli yet, prepare to meet one of the most original, insightful voices in the media landscape of personal finance and investing. (His last name is pronounced “ma - julie,” and his godfather refers to him as “paper hands,” but that latter point is a different story for another day.) Nick is a data scientist with a knack for clear written communication, a rare Venn Diagram intersection of skill sets. He holds a laser-focused interest in the arenas of personal finance and investing, and he’s eager to share fresh, nuanced, evidence-backed takes about savings, spending and investing with anyone who will listen. He recently released his first book, Just Keep Buying; the title reflects a user-friendly reminder to continue dollar-cost averaging. It also speaks to the main idea behind wealth creation: accumulate income-producing assets, consistently, for as long as you possibly can. It’s an honor to welcome Nick Maggiulli onto the Afford Anything podcast for what I hope is the first of many appearances. In today’s episode, we discuss actionable strategies for managing your money, including assessing your spot along the save-invest continuum, implementing the 2X rule into your spending decisions, and saving half of your inflation-adjusted future raises.
