How much can I earn while on social security

If you wait to start Social Security until your maximum retirement age, you can earn as much as you like. However, there are restrictions on how much you earn if you start your benefits early -- at age 62.

And, here is a pitch for delaying the start of Social Security:
if you wait until age 70 to start Social Security, your monthly benefit could be more than double what it was at 62. To maximize retirement income, many experts recommend retirees consider the following rule of thumb:
-- Don’t take Social Security at age 62 unless you have a very short life expectancy.
-- If you think that you will likely die before 80, start Social Security sometime between ages 65 and 67.
-- If you think that you will live beyond 85, delay the start of Social Security until you are 70.
