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.
The Social Security Administration sets the early retirement age â the youngest age that you can start collecting Social Security â at 62 years old. However, if you take benefits before your full retirement age â which ranges from 65 years old to 67 years old depending on the year you were born â your monthly benefit will be reduced.
