Fers Pension Calculator
If you’re a federal employee planning your retirement, one of the most important questions you have is: How much will I receive from my FERS pension? Our FERS Pension Calculator makes answering that question fast and easy. With just three pieces of information—your years of service, high-3 salary average, and current age—you can get an instant estimate of your annual retirement income under the Federal Employees Retirement System (FERS).
This tool is perfect for federal workers approaching retirement or anyone planning their long-term financial future within the civil service system.
🔍 What Is the FERS Pension?
FERS, or the Federal Employees Retirement System, is the primary retirement plan for most U.S. civilian federal employees. It consists of three main components:
- Basic FERS Pension (defined benefit)
- Social Security
- Thrift Savings Plan (TSP)
The basic FERS pension provides a guaranteed monthly income based on your service and earnings. It’s calculated using a formula that factors in your years of service, high-3 average salary, and a multiplier based on your age and tenure. This calculator focuses on that first component—your annual pension estimate.
🛠️ How to Use the FERS Pension Calculator (Step-by-Step)
Using this tool is straightforward and only takes a few seconds:
Step 1: Enter Your Years of Service

Step 2: Enter Your High-3 Average Salary
This is the average of your highest-paid three consecutive years of service. Often, this is your last three years, but not always.
Step 3: Enter Your Current Age
Your age helps determine which pension multiplier applies to your situation.
Step 4: Click “Calculate”
The calculator instantly shows your estimated annual pension based on the FERS formula.
Step 5 (Optional): Click “Reset”

🧮 How Is the FERS Pension Calculated?
The basic FERS pension is calculated using the following formula:
FERS Annual Pension = High-3 Salary × Years of Service × Multiplier
- Multiplier is 1.0% if under age 62 OR less than 20 years of service.
- Multiplier is 1.1% if age 62 and 20+ years of service.
This tool automatically applies the correct multiplier based on your input.
📘 Example Scenarios
Example 1: Federal Worker Age 60 with 25 Years of Service
- High-3 Salary: $80,000
- Years of Service: 25
- Age: 60
Multiplier: 1.0%
Calculation:
$80,000 × 25 × 0.01 = $20,000/year
Example 2: Federal Worker Age 63 with 30 Years of Service
- High-3 Salary: $100,000
- Years of Service: 30
- Age: 63
Multiplier: 1.1% (eligible due to age 62+ and 20+ years)
Calculation:
$100,000 × 30 × 0.011 = $33,000/year
