Starting at 62
For people born in 1958, starting at 62 is 56 months before full retirement age. The Social Security Administration puts the reduction at about 28.33%, so a $1,000 benefit becomes about $716. A spouse's benefit is cut by about 33.33% at 62.
Waiting until 70
Each month you wait past full retirement age adds 2/3 of 1%. From 66 and 8 months to 70 is 40 months, which adds 26.67%: $1,000 becomes about $1,267.
Two details
If you were born on January 1, Social Security treats you as born the year before. And if you delay benefits past 65, the agency says you should still apply for Medicare within 3 months of your 65th birthday.
