Q. How is my annuity reduced after working full time for seven years, part time for 10 years and then full time for an additional 13 years? Is it still the high-3, or is there a reduction because of less money contributed for those 10 part-time years?
A. You’ll get full credit for the time; however, your annuity will be reduced proportionate to the amount of your service that was part-time.
You can see how that’s done at www.opm.gov/retirement-services/publications-forms/csrsfers/c055.pdf; scroll to Part 55A2.
