When it comes to planning for retirement, all investors can agree on one thing: save early and save often. But as the Baby Boomer generation has started to retire, the topic of decumulation, or spending down one’s retirement assets, is gaining prominence – and it’s far from a straightforward exercise.
When it comes to planning for retirement, all investors can agree on one thing: save early and save often. After all, accumulating a retirement portfolio through good long-term investing habits can allow you to enjoy a great deal of financial flexibility in your post-working years.
However, over the past 10 years, as the Baby Boomer generation has started to retire, the topic of decumulation, or spending down one’s retirement assets, has gained more prominence. With over 10,000 individuals in the U.S. turning 65 each day1, decumulation is likely to remain an important topic for many years to come. Unfortunately, it can be far from a straightforward exercise. Investors face competing objectives, including a desire to maximize the income they draw from their portfolio, minimizing the variability of that income from year to year, and ensuring that their portfolio will support their spending needs throughout their lifetime.
What makes it so difficult to achieve these goals simultaneously is that investors in retirement are very susceptible to sequence of returns risk. What does that mean? Simply that retirees decumulating their portfolio may realize different retirement outcomes just due to the sequence in which market returns occur. Said another way, when you retire can be as important as how much you have when you retire.
The examples below illustrate the portfolio value over time of three different hypothetical investments which all had an average annual rate of return of 7%. For an investor in the accumulation phase, all three investments would have ended with the same value, although they experienced different paths to get there, as shown in the first chart. This story changes, however, when an investor enters retirement and begins to decumulate. Portfolio withdrawals compound losses, making it harder to recover from a portfolio decline, especially one that comes early in the sequence. The second chart illustrates the same three portfolios, but we’ve now added $60,000 inflation-adjusted annual withdrawals. Sequencing risk can be biting: while one investor would have run out of money before the end of the 20 years, another would have ended the period with more than her starting assets!
