Prudent Withdrawal Rate

Even if the probability of success for a 4% withdraw rate is less than some thought, it’s still strong when your portfolio is monitored actively.

Tom Lauricella’s column last week in the Wall Street Journal questions the reliability of being able to withdrawal 4% to 5% from your portfolio throughout retirement. See “Why Your Nest Egg May Not Last.” The so-called “Safe Withdrawal Rate” is from a study done by Trinity University in 1998 that examines the likelihood of a portfolio lasting over various periods of time when you withdraw a fixed percentage and adjust that amount up each year with the rate of inflation. The column quotes a new study from Ed Easterling’s book Probable Outcomes that shows the 95% probability of success for a 4% withdrawal dropping to 76% if you retire when stocks are in the top 20% of their historic valuation.

It is important to note that there is no such thing as a truly safe withdrawal rate. Investment returns and inflation are always uncertain. This does not mean that it’s time to abandon the Trinity Study or buy an annuity to guarantee a portion of your income. From a practical standpoint, we do not set up 4% distributions and then ignore what’s going on with the portfolio. A 76% probability of success is an acceptable projection when you’re monitoring the portfolio. Minor adjustments can easily be made long before the portfolio is at risk of being depleted which will increase the likelihood of success.

We advise clients to start their distribution at no more than 4% of the portfolio value. Then we monitor withdrawals with the objective of avoiding a distribution rate that exceeds 6% of the portfolio value in down markets. This means that a portfolio would need to lose a third of its value before withdrawals should be reduced. The original amount of withdrawal could be quickly restored as soon as the portfolio value recovers.

I believe the 4% withdrawal rate is still a prudent amount to use to project retirement income from a balanced portfolio. Adjustments may need to be made along the way because uncertainty will always be with us. The best defense is to always have control of your spending. That way you can quickly trim your spending if necessary in a down market.
