3 Reasons You Might Regret Claiming Social Security at 70
Age 70 is far from the most popular to sign up for Social Security. In fact, seniors most commonly claim benefits at 62 because that's the earliest age they can file.
Signing up at full retirement age, or FRA -- which is age 66, 67, or somewhere in between -- is another common choice. But many seniors don't want to wait until their 70th birthday to start collecting benefits.
There's an upside to holding off on filing for Social Security until the age of 70. For each year you delay your claim beyond FRA, your benefits grow 8%.
