Q. I am retiring in January with 36 years in. The last 6 were part time (20 hours per week). Looks like they are using my high-3 from the last three (part-time) years. After 36 years in CSRS, I’m getting basically 50 percent or less! You mentioned some court case where CSRS was found unlawful and they are using FERS calculations. Could you give me specifics so I can look up that case?
A. Because of a court decision, the method for computing a CSRS annuity with part-time service is the same as the one for FERS. You can find that method by going to www.opm.gov/retirement-services/publications-forms/csrsfers-handbook/c055.pdf and scrolling to Subchapter 55B2.
