Bill Bengen Discusses His Retirement Withdrawal Strategy


William “Bill” Bengen, whose 1994 study introduced the concept of the 4% withdrawal rate for retirees, recently participated in a question and answer session on social media website Reddit. The conversation focused on retirement withdrawal strategies and portfolio allocation. I’ll provide some highlights here. The full exchange is interesting, though you will want to set aside some free time as it encompasses nearly 450 questions and comments in total. Keep your eyes open for an interview with Bengen to appear in the AAII Journal early next year.

Not surprisingly, there were several questions about Bengen’s withdrawal strategy. chartThe 4.5% rule is a guideline for how much can be safely withdrawn each year without causing the retiree to run out of money over a period of 30 years. As such, it is referred to as a safe withdrawal rate (SWR). The strategy starts by withdrawing 4.5% of portfolio assets (Bengen has increased the percentage since his original research was published). The dollar amount is then increased by inflation each year thereafter. [Bengen uses the consumer price index (CPI) for determining by how much the withdrawals should be increased.]

There were several questions about whether or not the 4.5% rule is still applicable in the current environment. Bengen believes the state of the economy has had “little bearing on safe withdrawal rates.” Rather, he thinks the big dangers are encountering a “major bear market early in retirement” and/or experiencing high inflation during retirement. (Bengen called inflation “the retiree’s worst enemy.”) Though the average safe withdrawal rate has historically been 7%, a bear market similar to what occurred in 1937 or 2000 drops the SWR to 5.25%. Adding in the heavy inflation of the 1970s lowers the SWR to 4.5%. Bengen then added, “So far, I have not seen any indication that the 4.5% rule will be violated.” Continue Reading »
