The article "FBI Retirement Benefits: The Complete Guide to Federal Retirement Planning" explains the benefits FBI agents receive under FERS (Federal Employees Retirement System). It covers three key components: a pension based on the highest three-year average salary, Social Security eligibility, and the Thrift Savings Plan (TSP), which functions similarly to a 401(k). Agents can retire at 50 with 20 years of service or at any age with 25 years. The guide also outlines additional perks like health insurance, locality pay, and student loan assistance to help agents secure a stable retirement.
