Q. If I retire early and can receive the Social Security supplement at age 56, how can I find out from Social Security how much I will be getting each month in the supplement?
A. You can’t. You’ll have to go to www.ssa.gov/mystatement and get an estimate of your Social Security benefit at age 62. When you have the figure, plug it into the following formula: Social Security benefit estimate x your total years of FERS service rounded to the nearest year ÷ 40.
