Full retirement age is 67 for anyone born in 1960 or later, and 66 for people born from 1943 to 1954; for births in 1955 to 1959 it rises by two months a year. Claiming at 62 with a full retirement age of 67 pays 70% of your full benefit; waiting to 70 pays 124%.

Born on January 1? Use the previous year: Social Security treats you as reaching an age the day before your birthday. The percentages are computed from the statute: benefits drop by 5/9 of 1% for each of the first 36 months before full retirement age and 5/12 of 1% for each month beyond that, and delayed retirement credits add 2/3 of 1% per month (8% a year) up to age 70 (42 U.S.C. §402(q) and (w) (reduction and delayed credits); SSA, Retirement age and benefit reduction).
