Remember...Social Security does have an earnings limit if you retire early.

The Social Security website provides an example:

You begin receiving your Social Security benefits at age 62 in January 2014. At age 62, you are entitled to $800 a month in benefits. ($9,600 for the year)

You work and earn $23,480 ($8,000 over the $15,480 limit) in 2014. Your Social Security benefits would be reduced by $4,000 ($1 for every $2 you earned over the limit), but you would still receive $5,600 of your $9,600 in benefits for 2014.($9,600 - $4,000 = $5,600)
