This Could Be the Worst Social Security Decision You'll Ever Make
One positive aspect of Social Security is that you're allowed to sign up for benefits when you want to, albeit within an eight-year window. That gives you lots of choices in the context of retirement planning.
The earliest age at which you can claim benefits is 62. But for each year you file for benefits before full retirement age (FRA), your benefits get reduced. FRA begins at 66, 67, or somewhere in between, depending on your year of birth.
You're also allowed to delay benefits beyond FRA. For each year you do, up until age 70, your benefits will grow 8%.
