What Is the FERS Retiree Annuity Supplement (RAS)? Eligibility, Calculation, and Rules
By Tim Hayes, Financial Advisor for the Public and Not-for-Profit Sector
What Is the RAS
The Retiree Annuity Supplement (RAS) is unique to FERS. OPM pays it in addition to the FERS basic annuity. It’s intended as a substitute for the Social Security benefit portion of your complete FERS benefit package, from the date of retirement until you turn 62 — the earliest age Social Security itself becomes available.
Receiving it isn’t an election. If you’re eligible, OPM pays it automatically — no application or opt-in required.
RAS belongs to the retiree alone. It doesn’t pass to a surviving spouse. A separate, distinct benefit — the Survivor Supplement — covers that instead, with its own eligibility rules and its own end date.
Who Is Eligible for RAS
For a federal employee, RAS eligibility comes down to retiring on an immediate, unreduced pension before 62. Two standard paths get you there: MRA + 30 years of service, or age 60 + 20 years of service.
Special provision employees — law enforcement, firefighters, air traffic controllers, CBP officers — have their own third path, with earlier eligibility and different rules. That’s covered in its own section further down.
There’s a fourth route too: involuntary retirement, or voluntary early retirement taken during a major agency reorganization, reduction-in-force, or early-out authority. This one still leads to RAS — but the payments don’t start right away. They’re deferred until you reach your MRA, even if you retired well before it.
Anyone on the MRA+30 or 60/20 path faces the same decision: retire now at 1% plus RAS, or work to 62 for 1.1% with no RAS. Special provision employees don’t face this choice — their multiplier doesn’t hinge on reaching 62.

What the RAS Actually Pays
Here’s a rough way to estimate the RAS. Take your years of creditable civilian FERS service. (Purchased military time doesn’t count, unless it’s USERRA time.) Divide by 40. Multiply that by the Social Security benefit SSA says you’d get at 62.
Example: 22 years of service, $2,400/month SSA estimate.
22 ÷ 40 = 0.55 0.55 × $2,400 = $1,320/month
Example: 30 years of service, same SSA estimate.
30 ÷ 40 = 0.75 0.75 × $2,400 = $1,800/month
The ratio tops out at 1.0 — full credit — at 40 years. Getting to 40 years and still qualifying for RAS is rare. It usually means starting federal work in your late teens or early twenties, then retiring well before 62 via MRA+30.
The Earnings Test: Where the RAS Gets Complicated
The RAS isn’t locked in for good for a federal employee who’s already retired. It’s checked every year against an earnings test. The rules copy Social Security’s early-retirement test almost exactly.
For 2026, the exempt amount is $24,480. Stay under that in wages or self-employment income, and OPM leaves your RAS untouched. Go over it, and OPM cuts your RAS by $1 for every $2 you earn above the limit.
A worked example. Say your RAS is $12,000 a year — $1,000 a month. Want to know when it hits zero? Double the RAS. Add the exempt amount.
$12,000 × 2 = $24,000 $24,000 + $24,480 = $48,480
At $48,480 in earned income, this retiree’s RAS drops to zero. The cut is a straight line the whole way. At the midpoint — $36,480 — the RAS is cut exactly in half, to $6,000.
Three details worth knowing before you plan around this:
- Only earned income counts. Wages and self-employment income trigger the cut. TSP withdrawals don’t. Pension income doesn’t. Rental and investment income don’t either. A retiree living off TSP withdrawals instead of a paycheck sees no RAS reduction from that money.
- The cut is a year behind. OPM sends a survey each April asking what you earned last year, not this year. The cut based on that survey usually lands in the following year’s checks, spread across twelve months. So there’s a real lag between earning the money and seeing the adjustment.
- RAS stops cold at 62, no matter what. Once you turn 62, the supplement ends, and your real Social Security benefit takes over. The earnings test only matters in the years between your retirement date and your 62nd birthday.
Special Provision Employees: A Different RAS Timeline
Yes — law enforcement officers, firefighters, air traffic controllers, and CBP officers get RAS. They qualify the same way regular FERS employees do, just through their own age-and-service combination: age 50 with 20 years of covered service, or any age with 25 years of covered service, well ahead of a standard MRA.
What’s different isn’t whether they get it — it’s the timing and the earnings test.
RAS starts immediately at retirement, not at MRA. A federal LEO retiring at 50 starts collecting RAS that same year — not five or seven years later when they’d otherwise reach MRA.
No earnings test until MRA. A regular FERS retiree on RAS gets hit with the $1-for-$2 earnings test right away. A special provision retiree is exempt until MRA — typically 55 to 57. Income earned before MRA doesn’t touch the RAS. Income earned after MRA does.
That’s their real decision: how much to work before MRA, while it’s free, versus after, once the standard test applies.
The retirees who benefit most started covered service young — early-to-mid 20s — since that gets them to 20 or 25 years well ahead of MRA, opening a long exempt window. Someone who starts closer to 35 retires near their MRA anyway, and the window shrinks to almost nothing.
One note on military buyback: purchased military time can count toward the general FERS service thresholds once the deposit is paid. Still, it doesn’t count toward the 20- or 25-year covered-service requirement for special provision retirement unless that military time was itself served in a covered role.
Running the Actual Trade-Off — Regular FERS Retirees
Should you retire early with RAS, or work to 62 for the 1.1% multiplier? That’s not a rule of thumb — it’s arithmetic specific to your numbers. Three things move the answer most:
How big is your pension base? The gap between 1.1% and 1% compounds across your whole High-3 salary, every year of service, for life. On a large pension, that 10% permanent bump can beat several years of RAS bridge money.
How many years does RAS actually bridge? Retire at 60, and RAS covers two years before it ends at 62. Retire at 55, and it covers seven. More bridge years favor early retirement. Fewer years close the gap fast.
Will you keep earning after you retire? Step away from paid work entirely, and the earnings test never touches your RAS — you get the full run of it. Take on part-time work, consulting, or a second career, and the earnings test can claw back a big share of it. Sometimes most of it. That changes the math fast.
None of these numbers stand alone. Years of service, High-3 salary, your real SSA estimate at 62, and your plans to keep working — all of it has to go into one calculation before “retire early” or “work to 62” has a real answer for a federal employee in your specific situation.
