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.
Updated August 08, 2017. Full Retirement Age (FRA) is not the same age for everyone, as it is determined by your day and year of birth. It is the age at which you are eligible to receive your full amount of Social Security benefits. If you collect benefits earlier than FRA, your benefits are reduced. The earliest you can collect Social Security retirement benefits is age 62. If you begin benefits later than FRA your benefits are increased as you get the benefit of something called delayed retirement credits.
