Consider these twin concepts—opportunity cost and delayed retirement credits—before you decide when to start taking Social Security.
By waiting until age 70, you’ll increase your monthly benefit, but at what cost? A recent article in Forbes, “Social Security Benefits: Getting Paid To Wait,” examines the dilemma. Money managers call it “opportunity risk:” if you take money from retirement accounts that would otherwise be invested and grow, in order to delay taking Social Security, you are risking the potential for that money to grow.
Can you plan for opportunity cost? Start by looking at whether to wait to take Social Security after your “normal” retirement age, which is 66 for most people. If you wait to claim at age 70, you’ll see the largest-possible Social Security benefit. If you’re not working, you’ll probably be withdrawing money from your retirement funds, which means that those funds won’t be able to grow for a period of several years. As a result, you’ll need to weigh the opportunity cost of not having funds growing tax-deferred in your retirement accounts, against the larger Social Security benefit you will eventually get.
