Your key ages
If you were born in 1947, your full retirement age is 66. You reach it in 2013. 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, 1947, you are treated as born in 1946, and the rules for 1946 apply to you (see the 1946 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 1947 would get on your record, as a share of your full benefit.

|---|---|---|---|---|
| 62 | 2009 | 75% | $1,500 | 35% |

| 64 | 2011 | 86.7% | $1,733 | 41.7% |

Where you stand in 2027
You turn 80 in 2027. There is nothing to gain from waiting any longer: delayed credits stop at 70. If you have not claimed, apply now. Social Security can pay up to six months of back benefits once you are past full retirement age.
