FERS Supplement Bridge Calculator
Estimate your Special Retirement Supplement (SRS) — the bridge from early retirement to Social Security at 62
The FERS Supplement (also called the Special Retirement Supplement or SRS) is a bridge payment that replaces the Social Security income you would have earned if you hadn't retired early. It pays from your retirement date until age 62, when Social Security begins. Use this calculator to estimate your monthly supplement, check your eligibility, and see total bridge payments.
Your Retirement Details
Special provisions apply to law enforcement officers, firefighters, and air traffic controllers
Your Minimum Retirement Age (MRA) is 57 based on your birth year
Earliest: age 57 (your MRA). Must be before 62 to receive the supplement.
Total creditable FERS years (capped at 40 in the formula)
Your estimated monthly SS benefit at 62 (PIA). Check your mySSA account.
Earnings from a post-retirement job (triggers the earnings test)
No COLA: The FERS Supplement does not receive annual cost-of-living adjustments. It is a fixed payment based on your estimated Social Security benefit at age 62, and stays the same until it stops at 62.
How it works:
Formula: Monthly SRS = (FERS years ÷ 40) × estimated SS benefit at 62
Example: 30 FERS years, $2,000/mo SS → (30÷40) × $2,000 = $1,500/mo
Earnings test: Reduced by $1 for every $2 earned above $24,480 (2026) until age 62
Ends at 62: The supplement stops when you become eligible for Social Security

Special Provision Retirement — Who Qualifies Early
Certain federal employees in physically demanding or high-risk jobs qualify for special provision retirement — earlier retirement with an enhanced pension multiplier and full FERS Supplement eligibility. These employees can retire as early as age 50 with 20 years of covered service, or at any age with 25 years. The pension formula uses 1.7% per year for the first 20 years (instead of 1%), then 1% for each year beyond 20 — meaning a 20-year LEO retiring at 50 receives 34% of high-3 (1.7% × 20), plus the full SRS bridge to age 62.

Special Provision Pension Formula vs. Regular FERS
| Factor | Regular FERS | Special Provision |
|---|---|---|
| Earliest retirement age | MRA (55–57) | Age 50 |
| Min. service (early) | 10 years (MRA+10, reduced) | 20 years (unreduced) |
| Pension multiplier (first 20 yrs) | 1.0% | 1.7% |
| Pension multiplier (years 21+) | 1.0% | 1.0% |
| FERS Supplement (SRS) | Yes (if under 62) | Yes (if under 62) |
| Mandatory retirement | No | ATC: age 56; LEO & CBPO: age 57; FF & others: none |
Example: 20-Year LEO at Age 50
A law enforcement officer with a $100,000 high-3 salary and 20 years of covered service retires at 50. Pension = $100,000 × 20 × 1.7% = $34,000/year. If their estimated SS at 62 is $2,000/mo, the SRS = (20÷40) × $2,000 = $1,000/month for 12 years (age 50 to 62).
Example: 25-Year Firefighter at Any Age
A firefighter with 25 years of covered service can retire at any age. Pension = high-3 × (20 × 1.7% + 5 × 1.0%) = high-3 × 39%. The SRS = (25÷40) × SS at 62 — a larger supplement because more years of FERS service means a higher proration factor.
Important: Covered Service Rules
- • Only years in a primary special provision position count toward the 20/25-year requirement
- • Years in non-covered positions (e.g., supervisory or administrative roles) may not qualify
- • Mixed service (some covered, some regular) requires careful proration — contact OPM
- • Air traffic controllers face mandatory retirement at age 56; LEOs and CBPOs face mandatory retirement at age 57 — the SRS bridges the gap to Social Security at 62 in both cases
- • Military buyback can add years, but only covered civilian service counts for the 20/25-year threshold
Who Can Receive the FERS Supplement?
The FERS Special Retirement Supplement (SRS) is available to FERS employees who retire before age 62 under specific eligibility paths. It bridges the gap between your retirement date and the start of Social Security at 62. Below are the five ways to qualify, the earliest age you can start, and how long the supplement lasts.
| Retirement Path | Earliest Age | Min. Service | Pension Reduced? | Supplement? |
|---|---|---|---|---|
| MRA + 30 (Regular FERS) | MRA (55–57) | 30 years | No | Yes |
| MRA + 10 (Regular FERS) | MRA (55–57) | 10 years | 5%/yr if under 62 | Yes |
| Age 60 + 20 (Regular FERS) | 60 | 20 years | No | Yes |
| Age 50 + 20 (Special Provision) | 50 | 20 years | No | Yes |
| Any Age + 25 (Special Provision) | Any age | 25 years | No | Yes |
When It Starts
The supplement begins on your retirement date — the day after you separate from federal service. Your first payment typically arrives within 4–8 weeks, once OPM processes your retirement paperwork. Interim payments may be issued while your final annuity is calculated.
How Long It Lasts
The supplement pays from your retirement date until age 62 — the earliest age you can claim Social Security. Retiring at 57 means 5 years of payments. Retiring at 50 under special provisions means up to 12 years. It stops at 62 regardless of whether you actually claim Social Security.
When It Ends
The supplement stops at age 62 — no exceptions. At that point, you become eligible to claim Social Security retirement benefits, which the supplement was designed to replace. If you delay claiming Social Security past 62, you will have a gap in income unless you have other sources.
Minimum Retirement Age (MRA) by Birth Year
Your MRA determines the earliest age you can retire under FERS and receive the supplement. Special provision employees (LEO, firefighters, ATC) are exempt from the MRA requirement and can retire as early as age 50 with 20 years of service.
Understanding the FERS Supplement (SRS)
What It Is
- Bridge payment: Replaces SS income until age 62
- Paid by OPM: Not a Social Security payment
- Formula: (FERS years ÷ 40) × SS at 62
- Taxable: Subject to federal income tax
Who Does NOT Qualify
- CSRS employees: Only FERS employees receive SRS
- Age 62+: Supplement stops when SS begins
- Disability retirement: Different rules apply
- Deferred retirement: No supplement if you leave before MRA
The Earnings Test
The FERS Supplement is subject to the Social Security annual earnings test until age 62. If you work after retiring and earn above the exempt amount, your supplement is reduced. In 2026, the exempt amount for those under full retirement age is $24,480. For every $2 you earn above that limit, your supplement is reduced by $1.
FERS Supplement FAQs
How is the FERS Supplement calculated?
The supplement equals your estimated Social Security benefit at 62, prorated by your years of FERS service: (FERS years ÷ 40) × SS benefit at 62. For example, 30 years of FERS service with a $2,000 estimated SS benefit = (30÷40) × $2,000 = $1,500/month.
What is the earliest age I can receive the FERS Supplement?
For regular FERS employees, the earliest is your Minimum Retirement Age (MRA), which ranges from 55 to 57 depending on your birth year. For special provision employees (law enforcement officers, firefighters, and air traffic controllers), the earliest is age 50 with 20 years of service, or any age with 25 years of service.
What is the minimum years of service required?
It depends on your retirement path: MRA+10 requires 10 years of service (pension reduced 5%/year if under 62), MRA+30 requires 30 years (unreduced), age 60+20 requires 20 years, and special provisions require 20 years (at age 50) or 25 years (at any age). You must also be under age 62 when you retire.
How long does the FERS Supplement last?
The supplement lasts from your retirement date until age 62 — the earliest age you can claim Social Security. If you retire at 57, you receive it for 5 years. If you retire at 50 under special provisions, you receive it for up to 12 years. It stops at 62 regardless of whether you claim Social Security.
When does the supplement stop?
The FERS Supplement stops at age 62 — the earliest age you can claim Social Security retirement benefits. It is designed as a bridge to replace the Social Security income you would have received if you had not retired early. If you delay claiming Social Security past 62, you'll have an income gap.
Is the FERS Supplement taxable?
Yes, the FERS Supplement is subject to federal income tax. However, it is not subject to Social Security or Medicare taxes (FICA). Many retirees choose to have federal income tax withheld from their supplement payments.
Can I work and still receive the supplement?
Yes, but your earnings may reduce the supplement through the annual earnings test. If you earn above the exempt amount ($24,480 in 2026), your supplement is reduced by $1 for every $2 over the limit. The test applies until age 62.
Do CSRS employees get the FERS Supplement?
No. The FERS Supplement is only available to FERS employees. CSRS employees do not receive a special retirement supplement. If you transferred from CSRS to FERS (CSRS Offset), different rules may apply — contact OPM for details.
