If you're married, then your spouse faces the same decision, and your situation becomes more complex if your spouse worked most of his or her career and will be receiving a significant Social Security income based on his or her own earnings record.
To help you determine the best age for you and your spouse to start benefits, I'm going to borrow some words of wisdom from author Andy Landis, who offers an excellent description of the considerations you need to take into account in the latest edition of his book, Social Security: The Inside Story. According to Landis, here's what you have to do: "Remember two numbers: age 78 and age 82-1/2." Let's see why he says this.
We're going to look at three people born in 1950, all currently earning $75,000 per year and all earning similar amounts in prior years, adjusted for wage inflation. All three plan to stop working at age 62. Person A plans to start Social Security at age 66 (the Full Retirement Age for these three individuals). The initial monthly income for this age-66 starter will be $2,000 per month. Person B plans to start Social Security at age 62 and will receive $1,500 per month. Person C is going to wait until age 70 to start Social Security and will receive $2,640 per month.
Now let's compare the age-66 starter with the age-70 starter, using the same logic. The age-70 starter will catch up to the age-66 starter if he or she lives to age 82-1/2. By age 85, the age-70 starter will be "money ahead" of the age-66 starter by $19,200 and ahead of the age-62 starter by $61,200. If the age-70 starter lives to age 90, he or she will be ahead of the age-66 starter by $57,600 and ahead of the age-62 starter by $129,600.
So if you think you'll live until age 78, then waiting to start your benefits until age 66 is the best strategy. And if you think you'll make it to age 82-1/2, then waiting to start benefits until age 70 is the best strategy for you. The difference in total benefits is one very important reason why estimating your life expectancy should be a critical part of your retirement planning. Two good websites that offer calculators to help you do this are www.livingto100.com and www.bluezones.com.
The "money-ahead" amounts shown above are just for one person; a married couple can gain higher amounts by carefully selecting the start date for each spouse, and could easily add over $100,000 in payouts over their joint lifetimes.
I agree with Andy's conclusions about Social Security start dates -- see my post, When Should You Start Social Security Benefits? Do the Math! for more on this topic.
Of course, Andy's analysis doesn't reflect such factors as inflation, cost-of-living increases, taxation of Social Security benefits, investment earnings, and wage earnings after age 62. But I've seen other analyses that do consider some of these factors (and significantly complicate the analysis), and they still result in nearly the same conclusions regarding "break-even" ages.
Don't let all the numbers you'll have to deal with intimidate you -- it's well worth your time to do the math and make informed choices about when to start your Social Security benefits. It could put many thousands of extra dollars into your retirement pockets.
