Federal LEO, Firefighter, and ATC Retirement Pay Examples: What the 1.7% Multiplier Actually Pays

How the Enhanced Annuity Formula Translates to Actual Pay

The special category retirement formula sounds straightforward — 1.7% of your high-three average salary for the first 20 years of covered service, then 1.0% for additional years. But translating that formula into a monthly deposit amount requires understanding which salary components count toward your high-three, how mixed service (covered plus non-covered years) factors in, and what happens to your annuity when you add sick leave credit.

The examples below use realistic salary figures drawn from current federal pay scales and account for the variables that most online retirement calculators either oversimplify or ignore entirely.

Example 1: Federal LEO Retiring at 50 With 25 Years

Profile: FBI Special Agent, GS-13 Step 10 with Law Enforcement Availability Pay (LEAP). 25 total years of federal service — 22 years of covered LEO service and 3 years of non-covered civilian service before transferring to the Bureau.

High-three calculation: A GS-13 Step 10 base salary in 2026 is approximately $119,000 (varies by locality). LEAP adds 25% of base pay, bringing adjusted salary to roughly $148,750. The high-three is the average of the three highest consecutive years of basic pay, including locality and LEAP. Assuming modest step increases, the high-three comes to approximately $146,500.

Annuity computation:

• First 20 years of covered service at 1.7%: $146,500 x 0.017 x 20 = $49,810 per year
• Next 5 years (2 covered + 3 non-covered) at 1.0%: $146,500 x 0.01 x 5 = $7,325 per year
• Total annual annuity: $57,135 ($4,761 per month)

That's roughly 39% of the agent's final working salary — before adding the FERS Supplement, TSP withdrawals, and eventually Social Security. This agent would also receive an immediate COLA adjustment in the following January and would be exempt from the FERS Supplement earnings test until reaching their MRA (age 56-57).

Example 2: Federal Firefighter Retiring at 57 (Mandatory Separation) With 30 Years

Profile: USDA Forest Service wildland firefighter, GS-09 Step 10 with firefighter premium pay. 30 years of federal service — 28 years of covered firefighter service and 2 years of early-career seasonal work that was non-covered.

High-three calculation: GS-09 Step 10 base is approximately $77,000. With overtime, night differential, and hazard pay during fire seasons, a career wildland firefighter's base pay (the figure that counts for the high-three) is approximately $79,500 averaged over the three highest years. Premium pay beyond base doesn't count toward the high-three; only base pay, locality adjustments, and certain within-grade increases factor in.

Annuity computation:

• First 20 years of covered service at 1.7%: $79,500 x 0.017 x 20 = $27,030 per year
• Next 10 years (8 covered + 2 non-covered) at 1.0%: $79,500 x 0.01 x 10 = $7,950 per year
• Total annual annuity: $34,980 ($2,915 per month)

At 57, this firefighter is past their MRA, so the FERS Supplement earnings test applies immediately. The supplement is based on creditable FERS civilian service, not automatically total federal service; if the two seasonal years are not creditable FERS civilian service, use 28/40 rather than 30/40 of the projected Social Security benefit at age 62.

Example 3: Air Traffic Controller Retiring at 56 (Mandatory Separation) With 26 Years

Profile: FAA air traffic controller at a Level 12 facility, ATCS pay scale. 26 years of continuous covered ATC service — no breaks, no non-covered civilian time.

High-three calculation: Level 12 facility controllers at the top of the CPC (Certified Professional Controller) band earn approximately $190,000 in base pay including the ATC premium. The high-three for this controller averages approximately $187,000.

Annuity computation:

• First 20 years of covered service at 1.7%: $187,000 x 0.017 x 20 = $63,580 per year
• Next 6 years at 1.0%: $187,000 x 0.01 x 6 = $11,220 per year
• Total annual annuity: $74,800 ($6,233 per month)

Controllers at high-traffic facilities are among the highest-paid special category employees, and the enhanced multiplier produces a correspondingly large annuity. This controller faces mandatory separation at 56 — one year earlier than LEOs and firefighters — but with 26 years of all-covered service, the annuity calculation is clean: no mixed-service complications.

How Sick Leave Changes These Numbers

In each example above, unused sick leave at retirement gets converted to additional service credit for annuity computation. The conversion rate is 2,087 hours per year of service. So 1,000 hours of unused sick leave adds approximately 5.7 months to your total service time.

That additional time is computed at the 1.0% rate (it goes beyond 20 years in all three examples). For the LEO example with a $146,500 high-three, 1,000 hours of sick leave adds roughly $700 per year to the annuity. Not transformative, but it compounds with COLAs over a 30-plus-year retirement.

The critical caveat: sick leave credit counts only for annuity computation, not for eligibility. If you have 19 years and 8 months of covered service plus 2,000 hours of sick leave, you still don't meet the 20-year threshold.

What These Examples Don't Include

These annuity figures are the basic FERS pension only. Your total retirement income also includes the FERS Supplement (bridge payment until age 62), Social Security benefits (starting at 62 or later), TSP withdrawals, and any post-retirement employment income. The full income picture depends on your TSP balance, your Social Security earnings record, and whether you work in the private sector after retiring.

The Special Category Retirement Guide includes an annuity calculation worksheet that walks through the full computation with your actual salary history, a FERS Supplement calculator, and a TSP contribution planner to help estimate your complete retirement income.
