The full retirement age for Social Security benefits depends on the year you were born. If you were born in 1957, your full retirement age is 66 and 6 months. However, if you were born in 1960 or later, your full retirement age is 67. You can start receiving Social Security retirement benefits as early as age 62, but your benefit amount will be reduced if you start before your full retirement age. The reduction is a small percentage for each month before your full retirement age
