If you’re a federal employee, you’ve probably heard these four acronyms more times than you can count — but that doesn’t always mean you know what they actually do for you. Here’s the plain-English version.
FERS (Federal Employees Retirement System) is built on three parts working together: a basic pension, Social Security, and your TSP. Most federal employees hired after 1987 are covered by FERS. It’s the foundation your retirement income sits on — not the whole picture, just the base.
The Thrift Savings Plan is your retirement savings account — similar to a 401(k) in the private sector. You contribute a percentage of your salary, your agency matches part of it, and you choose how it’s invested across different funds. How you allocate that money can make a real difference over a career.
Federal Employees’ Group Life Insurance is coverage available through your job. Most people are automatically enrolled in Basic coverage, with optional add-ons (Options A, B, and C). What people often miss: FEGLI costs increase as you age, especially for optional coverage — so what made sense at 30 may look very different at 55.
Social Security isn’t separate from your federal benefits — it’s one of the three legs of FERS. When you claim it (as early as 62, or as late as 70) changes your monthly benefit for the rest of your life. Timing here isn’t a minor detail.
None of these four pieces work in isolation. Your TSP strategy should account for your FERS pension. Your FEGLI coverage should reflect your actual life stage. Your Social Security timing should fit your full retirement picture — not be an afterthought.
