Your key ages
If you were born in 1958, your full retirement age is 66 and 8 months. You reach it in 2024 if you were born January through April, or 2025 if you were born May through December. Claim before then and your check is permanently smaller. Claim after and it grows by 8% a year until 70.
One detail catches people out: Social Security counts you as reaching an age the day before your birthday. If you were born on January 1, 1958, you are treated as born in 1957, and the rules for 1957 apply to you (see the 1957 page).
What each claiming age pays
The table shows the share of your full benefit you would get for life, and what that means on a $2,000 full benefit. The spousal column shows what a husband or wife born in 1958 would get on your record, as a share of your full benefit.

Where you stand in 2027
You turn 69 in 2027, which is past your full retirement age of 66 and 8 months. The earnings test no longer applies, so you can work and collect with no money held back. If you have not claimed yet, every month you wait until 70 adds two-thirds of 1% to your check for life.
