Planning for retirement requires a clear understanding of your timeline and the rules governing Social Security benefits. While you can claim benefits starting at age 62, doing so results in a permanent reduction of your monthly payment by up to 30 percent compared to waiting for your full retirement age. This age threshold is the specific point where you qualify for your total benefit amount.

Changes to this system began with the Social Security Amendments of 1983. Congress passed this law to adjust for longer life expectancies. Since 2021, the full retirement age has increased by two months each year for those born in 1938 or later. This gradual increase reached 67 years for individuals born in 1960 or later, which currently stands as the final age increase for the program.

Your specific full retirement age depends on your birth year. For those born between 1943 and 1954, the age is 66. It then increases by two-month increments for each subsequent year of birth. If you were born in 1955, the age is 66 years and two months. If you were born in 1956, it is 66 years and four months. Those born in 1957 reach this age at 66 years and six months, while those born in 1958 hit the mark at 66 years and eight months. For those born in 1959, the age is 66 years and 10 months.

Retiring before your full retirement age permanently lowers your check. Conversely, waiting beyond this age allows for an increase in your benefit amount by roughly 8 percent for each year you delay, up until age 70.
