Fers Deferred Retirement Calculator
If you’re a former federal employee under the Federal Employees Retirement System (FERS) who left before meeting immediate retirement requirements, you may still qualify for a deferred retirement. But how much will your pension be worth when you reach eligibility age?
That’s exactly what the FERS Deferred Retirement Calculator helps you answer. With just three key inputs, this free tool gives you a fast, clear estimate of your annual retirement benefit—even if you’re no longer in federal service.
In this article, we’ll explain how to use the calculator, walk through examples, and answer the most common questions federal employees have about deferred retirement under FERS.
🧮 What Does the FERS Deferred Retirement Calculator Do?
The FERS Deferred Retirement Calculator estimates your annual pension based on:
- Your High-3 Average Salary
- Your Years of Creditable Federal Service
- Your Age at Retirement (when you plan to start collecting)
The tool uses official FERS formulas to estimate your deferred benefit based on whether you meet eligibility thresholds (such as age 62 with 20 years of service). If you don’t meet those, it applies the standard 1% multiplier. If you do, it uses the higher 1.1% multiplier.
✅ How to Use the FERS Deferred Retirement Calculator (Step-by-Step)
Using the calculator is simple and only takes a minute:
Step 1: Enter Your High-3 Salary
This is the average of your highest-paid consecutive 3 years of federal service. Input this in dollars (e.g., 84,000).
Step 2: Enter Your Years of Creditable Service
Add up your years of full-time federal employment. Part-time and temporary service may count differently depending on your situation. You can use decimal values like 15.5 or 20.25.
Step 3: Enter Your Retirement Age
This is the age at which you plan to start receiving your deferred pension. For many, this is age 62 or older.
Step 4: Click “Calculate”
The tool will instantly compute your estimated annual pension, based on FERS deferred retirement rules.
🔍 Example: Deferred Pension Calculation
Let’s say you worked 17 years in the federal government, earned a high-3 average salary of $90,000, and you plan to begin your deferred retirement at age 60.
- High-3 Salary: $90,000
- Years of Service: 17
- Retirement Age: 60
You do not meet the special eligibility rule of age 62 with 20 years of service, so your multiplier will be 1.0% (0.01).
Estimated Pension = 90,000 × 17 × 0.01 = $15,300 annually
🧠 What Is FERS Deferred Retirement?
Deferred retirement allows federal employees under FERS who leave before reaching full retirement eligibility to still collect a pension later—if they have at least 5 years of creditable service.
You become eligible to receive that pension at a minimum age of 62, or earlier with more service:
| Age | Years of Service | Eligibility |
|---|---|---|
| 62+ | 5+ | Full deferred |
| 60+ | 20+ | Full deferred |
| MRA* | 10+ | Reduced deferred |
*MRA (Minimum Retirement Age) ranges from age 55 to 57 depending on your birth year.
🔄 When Is the 1.1% Multiplier Used?
FERS offers a bonus multiplier of 1.1% instead of 1% if:
- You retire at or after age 62
- AND have 20 or more years of creditable service
This results in a higher annual pension. The calculator automatically adjusts based on your inputs.
