(Bloomberg) — Every year, Americans give up thousands of dollars of income by filing for Social Security benefits too early. If you're anywhere near retirement, or want to help guide your parents, here's how to think about when to file—a once-in- a-lifetime decision with huge financial consequences.
You can start getting a monthly check at 62, but that locks in a reduced benefit for the rest of your life. Retirees currently get the full Social Security benefit at 66. Waiting even longer will fatten those checks further. File for Social Security as a single person at 70 and your monthly check can be76 percent higherthan if you had filed at 62. That's a source of income that automatically adjusts for inflation and will last as long as you do.
Of course, you could die before you get those higher benefits or get to enjoy them for long. But research suggests that for those with average life spans, it usually makes sense to wait.
Even for groups statistically more likely to die in their 60s, including African Americans and people without high-school diplomas, one study found that some delay in Social Security benefits makes sense. This is particularly true for couples in which one spouse—usually the man, in older male-female couples—is the main breadwinner.
"If you're a primary earner, not only do you get higher benefits for the rest of your life, you pass on higher benefits to your widow if you die first," says Sita Slavov, a professor of public policy at George Mason University.
Most Americans don't even hold out until they reach the full retirement age. Some need the checks to live on. But according to new research by Slavov and colleagues at Stanford University and the U.S. Treasury Department, many retirees could dip into savings but decide not to.
The study, issued this month, looked at tax data for Americans born in 1940. It found that about a third of people who file early for Social Security benefits had enough assets in individual retirementaccounts (IRAs) to make up for two years of Social Security checks. About a quarter had enough to cover four years of benefits. Retirees probably also had other savings, investments, and pensions that researchers weren't able to measure.
