Your FERS Pension
Your multiplier, your High-3, and what you actually get each month

Your gross pension is only the start. The survivor election, taxes, and FEHB each take a cut before the check clears.

How deductions reduce your gross pension to net take-home.
Estimate only; not financial, legal, or tax advice. Service time uses the OPM 30/360 method and the multiplier follows the applicable basis; sick-leave credit adds to the computation but not to eligibility, while bought-back military time counts toward both. Confirm your official figures with OPM and your HR/benefits office.
How your pension is computed
The FERS pension is a guaranteed lifetime annuity paid monthly. Controllers earn an accelerated multiplier, and the whole formula comes down to two numbers:
1. Your High-3 average salary
Your High-3 is the average of your highest 36 consecutive months of adjusted basic pay. For almost all air traffic controllers, this represents your final 3 years of service before retirement.
- Basic pay
- Locality pay
- Overtime Pay
- Holiday, Sunday & Night Premium Pay
- CIC & OJTI Premium Pay
- Differential Pay (CIP, COLA, etc.)
2. The multiplier: two computations
Regular federal employees earn a flat 1.0% per year. ATCs get special provisions, but which enhanced formula applies depends on how you retire.
The Standard Path: 1.7% capped at 20 years
This is the retirement route for the vast majority of controllers:
- The Gates: Retiring under ATC special early-out (Age 50 with 20 years of ATC service, or Any Age with 25 years) or mandatory separation at age 56.
- The Formula: You receive 1.7% of your High-3 for the first 20 years of total service, plus 1.0% for every year beyond 20.
- Total Service Counts: While you need 20 or 25 years of ATC "good time" to unlock the retirement gates, your actual pension calculation uses your total federal service years (including military buyback, non-ATC time, and sick leave) to compute the 1.7%/1.0% split.

The 30-Year Enhancement: 1.7% on every ATC year
A powerful, lesser-known provision (5 U.S.C. § 8415(f)) that removes the 20-year cap. If you qualify, every ATC year of your career earns the 1.7% multiplier. For example, a 30-year ATC career yields 51% of your High-3 instead of 44% (e.g. a $175,000 High-3 pays $89,250/yr instead of $77,000/yr).
- At least 5 years of FERS ATC service (as a controller and/or supervisor).
- Retire under FERS general rules (reaching Minimum Retirement Age (MRA) of 57 with 30 years of service).
The only practical way to follow this path as a controller is to move into a position which is exempt from mandatory separation at 56. Operations Manager is ideal, because you still receive ATC good time. Other federal positions can help you qualify for this path, but you will only earn 1.0% during those years.

ATC Pension Multiplier Comparison
Your multiplier determines the percentage of your High-3 salary you will receive as your starting gross pension. Below is a comparison of how your total pension percentage grows by career length (assuming all years are ATC service):
