When you start out with a faulty premise, you can't trust the results. You can't ignore income taxes and the cost-of-living adjustments in picking a strategy for when you should start receiving Social Security retirement benefits.
You can look to maximize payments received from Social Security, but numerous academic research papers point out that the "present value" of the total benefits paid out are about the same, regardless of when you start receiving them. Present value is a finance concept that considers the time value of money -- which is the focus of your letter.
I spoke with Bill Meyer, at Social Security Solutions, who tells me the best interest yield to use when considering the time value of money for Social Security payments is the yield associated with Treasury's inflation-protected securities, or TIPS. The actual rate is nowhere near the 4 percent number you cited. You could choose to take additional investment risk by investing in stocks or other investments. If we are talking about additional risk, then that makes this the proverbial apples-to-oranges comparison.
Which Social Security strategy makes the most sense? It depends on whether you're single, divorced or married, and also on the health and life expectancy of you and, if married, your spouse.
Besides trying to maximize the payments from the government, you would want to protect against longevity risk, or the risk of outliving your income.
A 2010 paper that appeared in the Journal of Financial Planning by William Meyer and William Reichenstein, "Social Security: When to Start Benefits and How to Minimize Longevity Risk," provides ideas on which strategy might be appropriate for different people.
It explains that single people who expect to live the average number of years get the same present value of benefits no matter when they begin. Single people with shorter life expectancies should take benefits early, and vice versa: Those with longer life expectancies should delay. Couples who want to take advantage of present value should have the lower-earning spouse take benefits as soon as possible, and the higher-earning spouse should delay until age 70.
I hope this helps you to better decide when to take benefits. Here's hoping you have a happy and long retirement!
