The man who created the 4% rule for retirement savings now wants you to spend more — says 5.5% is 'more realistic'

Bill Bengen, the creator of the 4% rule for retirement savings, now suggests retirees should consider spending 5.5% annually. In an interview with Business Insider, Bengen explained that the original 4% figure should be adjusted to 4.7% for more realistic conditions, but under current market conditions, he recommends a higher rate of 5.5%.

This adjustment could have significant implications for retirement planning and spending habits. Historically, the 4% rule advised retirees to withdraw 4% of their portfolio in the first year, with subsequent adjustments for inflation. Bengen's recommendation is based on a different calculation, taking into account factors such as stock market valuations, inflation expectations, and diversification benefits across various asset classes.

This newer approach allows for more conservative withdrawal rates, with a $1 million 401(k) generating an initial annual income of $40,000 under the 4% rule, $47,000 with 4.7%, or $55,000 at 5.5%.
