The Modernization of The 4% Rule For Retirement Savings

Bengen’s 4% Rule

The 4% rule has been in existence as far back as 1994. It was introduced by William Bengen, a financial adviser, as an answer to the question on how much a person can withdraw from his/her retirement savings yearly and still have enough to last for retirement years.

It is a rule which stipulates that the retirees who withdraw 4% of their retirement fund’s balance and subsequently adjust the balance for inflation yearly after that, would have a balance that could last for approximately 30 years. However, several experts have posited that there is a need to modernize this rule of thumb to suit the present day circumstances.

Shortcomings of The Rule

The most apparent issue which the 4% rule of retirement savings has is that it is laden with so many uncertainties. For instance, how many more years does the retiree have to live? What is the direction of inflation rate? What sort of healthcare needs will come up?

What effect will taxes have on the income? Etc. The answers to these questions show that the uncertainty of future occurrences may impact the utility of the rule in modern times. Ultimately, the uncertainties can primarily affect the income plan.

Also, the fundamental assumptions on which Bengen’s study rely have some flaws. On market returns, the study utilized withdrawal rates levied on the different portfolio of bonds and stocks by making use of investment returns and inflation data between mid-1990s and 1926.

Its portfolio assumption is 40% bonds and 60% stocks. It is worthy to note that bond returns at that period were near 5% which is way below what exists in the present day. Also, the market has become more volatile and having a futuristic approach while testing the different market conditions is likely to be helpful in determining how long a portfolio can last.

One other assumption surrounding the rule is the fact that it holds longevity of the portfolio as a core objective rather than income needs. This assumption may be a problem if the retiree’s sequence of spending weighs more in the first years of retirement than later years.

Thus, different strategies have been introduced to explore the various methods of managing sequence risk. Such strategies include, bucket strategy which refers to breaking down the retirement savings into buckets using time periods or lines of crediting for the protection of portfolio longevity.

Similarly, the Bengen study’s approach to taxation issues is quite simple. The method may have worked during the 1990s, but experts have posited that it is not capable of meeting up with the current situation considering how complex the current taxation issues are. For example, the types of retirement assets of present-day retirees have differing tax obligations. While some are tax-free, others are fully taxable.

Also, tax code in the process of taxing the different retirement fund sources has gotten more complicated. In fact, for retirees who are high-income earners, there is additional complexity in determining timing of the income obtained from required minimum distributions when they are 70½ years, qualified distributions, benefits of Social Security, while also managing the effect they have on taxes. Therefore, as a retiree’s wealth exceeds a need for qualified distributions or benefits of Social Security, it becomes essential to consider the actual impact of taxes on withdrawal strategy.

A recent study looks into the impacts of RMDs and benefits of Social Security on withdrawal strategies that are tax efficient.

The study concluded that portfolio longevity could be improved by utilizing a more detailed approach for the conversion of qualified assets to assets that are exempted from taxes in some of the retirement years. Also, it suggested the management of qualified withdrawals in a way that wholly covers standard deductions while also maxing out the lesser tax brackets for those years where the retiree does not need the income.

Starting- point Approach

Although the 4% rule has some shortcomings, it remains a good starting point when planning for retirement. Thus, it is suggested that the rule should be treated as a general technique for assessing your level of savings, but not as the ultimate or only means.

It may be used as the starting point, but upon retirement, the odds are high that there will be a need to carry out a yearly assessment to determine how best to go on with managing your income sources putting your expenses and tax and into consideration.
