Given the myriad of products and services available to today’s prospective retirees, there are a lot of choices to consider about which retirement income strategy to pursue, from portfolio-based withdrawal strategies to annuities with income guarantees and more.
Yet as it turns out, what seems like a relatively simple question – which retirement income strategy is the best – is actually remarkably difficult to determine. Because as it turns out, which is “best” depends heavily on how you measure what “best” really means in the first place.
For instance, when evaluating by what produces the most wealth, the best retirement strategy is generally to just not spend very much (and ideally invest for growth along the way, too)! If the goal is to maximize retirement spending, then the “best” strategy is to invest as aggressively as possible in order to maximize the portfolio growth that will substantiate that spending. Yet portfolios with maximal growth can also produce the greatest catastrophes, which means a risk-averse retiree may not want that approach, even if it would otherwise have increased retirement spending!
What all of this ultimately means is that in framing different retirement income strategies – and the trade-offs they might entail – it’s important to give serious consideration to the measuring stick that will be used to evaluate the potential retirement outcomes. Because the “best” retirement income strategy may be very different depending on whether you measure based on wealth, spending, probabilities of success, magnitudes of failure, or utility functions that weigh both the upside and downside risks!
