Social Security benefits account for 50 percent or more of retirement income for three out of five beneficiaries receiving Social Security benefits who are age 65 or older. Nearly one out of four received all of their income from Social Security in 2012.
But it can be a costly move. If you start taking Social Security at 62, rather than waiting until your full retirement age (FRA), you will receive reduced benefits. FRA ranges from 65 to 67, depending on the year in which you were born.
