401(k) and IRAs Understanding the 4% Rule

When you retire, you will likely rely on your 401(k) and IRA accounts as a source of income, but have you considered how you will withdraw from these accounts to support your lifestyle? There are a few different options available including fixed-dollar or fixed-percentage withdrawals, but one recommendation still stands the test of time: The Four Percent Rule! 

The Four Percent Rule Revisited 

Devised by William Bengen in 1994, the Four Percent Rule has been a fundamental element in retirement planning. It’s based on the premise that retirees can safely withdraw 4.2% from their savings each year and adjust this amount by roughly 2% annually to match inflation. There is a 90% chance your nest egg will last about three decades. There is no guarantee, but it can be a helpful guideline for retirees.  

Bengen tested this theory by looking back at retirements over 50 years from 1926 to 1976. Historically, this strategy has weathered various economic storms, including the stock market crash of 1929, the Great Depression, World War II, and the stagflation of the 1970s.  

It is fair to ask whether his formula still holds up. The short answer is yes, its resilience suggests it remains a sound approach for retirement spending today! But keep in mind that the formula is an estimate because everyone’s life situations are different.  

How Does the Four Percent Rule Work? 

Imagine your retirement portfolio is valued at $2.5 million. Under the Four Percent Rule, you would withdraw 4%, which is $100,000, in the first year. This sets the baseline for future withdrawals. 

Each subsequent year, you adjust the withdrawal amount to align with inflation. For instance, if inflation is 2% in the second year, you would withdraw $102,000. To adjust for inflation, retirees have a couple of options: 

Set a flat annual increase of 2% each year to align with the Federal Reserve’s target inflation rate. This option provides steady increases for participants. Adjust withdrawals based on actual inflation rates, which can be more effective in matching income to cost-of-living changes over the years. 

If you’re unsure of which path to take, talk to a financial advisor to determine which works best for you and your finances. You can also use the Four Percent Rule calculator to help you determine the savings required to withdraw annually. 

Advantages of the Four Percent Rule 

Using the Four Percent Rule has advantages for retirees: 

The Four Percent Rule is easy, straightforward, and simple to use. It provides a predictable and steady income for people in retirement, as well as the peace of mind of knowing their funds will not be exhausted for at least 30 years. It helps retirees keep a consistent withdrawal schedule without overextending their funds. 

Considerations for the Four Percent Rule 

While the Four Percent Rule is a helpful retirement tool, there are a few things to keep in mind when using it. 

Keep an eye on the market. Major market downturns can diminish the value of accounts, so by staying up to date with trends, you can make better investment and withdrawal decisions. Be consistent with withdrawals every year. When you increase or decrease your withdrawal amount, the principal and compound interest are affected. By maintaining a 4% withdrawal each year, you keep a steady account. If you are eligible for early retirement, you may need to adjust the amount you are withdrawing each year. Speak with your financial advisor before getting started. 

Is It Still the Key to Making Money Last in Retirement? 

For two decades, the 4% Rule has served as a magic number for financial planners and retirees to provide some structure and retirement withdrawal planning. While the original Rule was based on the concept of “worst-case” economic scenario and stock and bond returns, some argue that 3% or 5% would be a more realistic number in today’s calculations.  

Regardless, playing it safe with the 4% rule in calmer economic times may leave some with a huge amount of money left over which is not a bad problem. To learn more, read Barret’s interview with Bengen here.
