Deciding when to retire should not be a complicated matter. Unfortunately the Internet is making it so by amplifying bad advice to seniors suggesting that waiting to collect benefits is not only sensible but well worth the wait.
It is, of course, all nonsense. You cannot materially increase your expected Social Security benefits by changing your claiming date. This middle school math seems to befuddle PhDs, recognized financial gurus, and media outlets like the Wall Street Journal. They in turn have confused seniors with terrible advice that has been magnified by the Internet into urban legend.
Everyone understands that seniors want to get what's yours, but waiting until 70 is not the way to do it. You have a better chance of maximizing your benefits with Tarot cards than listening to experts on the issue of setting your claiming date.
What The Social Security Administration says
The Social Security Administration provides facts. It says that there is no expected increase in return by changing your claiming date.
"If you live to the average life expectancy for someone your age, you will receive about the same amount in lifetime benefits no matter whether you choose to start receiving benefits at age 62, full retirement age, age 70 or any age in between."
You can think of this comparison like the race between the tortoise (lower checks) and the hare (higher checks), where the Social Security Administration gives the tortoise a large enough head start that you expect a tight race at the finish. While checks claimed at age 62 are smaller, you get more of them over your life. Including interest on the early checks, the amount that you collect at age 62 from Social Security over a normal life is about the same as you get by waiting to age 70.
The basic mistake
You are probably wondering why you hear wildly different answers to the same question. The answer is simple. It is part ideology and part poor financial advice. Many writers ignore the interest that early-money would earn. Almost all ignore the risk of a reduction of future benefits, which is projected to occur within the lifetime of current retirees.
In a short article, I can't replace your personal financial advisor. I can tell you that if your financial advisor says that he didn't factor in time value of money, or he says that the risk of Social Security insolvency is overblown, it is time to replace your financial advisor.
Old-age insurance is wise, but trying to make money on it isn't
In deferring your claiming date, you are essentially buying additional old-age insurance from Social Security, trading current checks for future certainty. Insurance isn't about making money. It is about losing less money on an unexpected event. In the case of old age insurance, you will get a lot of money if you live to 100. Unfortunately that event will give you a lot of cost, as well. This isn't something that you buy in order to make money.
