I have a bit more than a year before I reach 62, so I will be investigating this more thoroughly in 2013. Just got an estimated SS statement in August.
Using those numbers - If I start drawing at 62 I will bring in more money than if I wait to start drawing at age 66 UNLESS I live beyond age 77. The monthly amount depends on how much you have made and contributed over your work-lifetime - I think . . .
Kinda depends how long you think you'll live. And THAT is a guess . . .
