Q. I would like to know how much my retirement refund would be with 16 years at the GS-07 level . I know you would not have an exact amount due to federal taxes but a ball park would help.
A. Your refund would be based on the amount of your contributions to the retirement fund, which you can find on your most recent pay slip, and accrued interest. Interest rates have varied from a high of 7.125 percent in 1994, when you entered on duty, to 3.125 percent in 2010.
