Q. I will be able to retire on Dec. 19, 2018, at 57 years old, so I will have the time and the age, but I will probably retire at the end of the month on the last full pay period in December. How do I calculate the FERS special retirement supplement between 2018 (age 57) and the time I turn 62 years of age?
A. Your special retirement supplement will be based on the amount of Social Security benefit you earned while a FERS employee. You’ll find the method used to determine that amount at https://www.opm.gov/retirement-services/publications-forms/csrsfers-handbook/c051.pdf. Just scroll to Part 51A2.
