Planning for retirement is one of the most important financial steps you can take as a federal employee. The Federal Employees Retirement System (FERS) provides a structured pension program, but understanding how much you’ll receive after retirement can be complicated.
That’s why we created this FERS Calculator tool — a simple and accurate way to estimate your annual and monthly pension based on your High-3 average salary, years of service, and retirement age.
In this guide, we’ll explain what the FERS Calculator is, how to use it, provide examples, and answer the most common questions federal employees have about their pensions.
FERS Calculator
🔎 What is the FERS Calculator?
The FERS Calculator is an online tool designed to help federal employees estimate their pension benefits under the Federal Employees Retirement System.
The FERS pension is calculated using a formula that considers:
- High-3 Average Salary (the average of your highest three consecutive years of pay)
- Years of Creditable Service
- Retirement Age
The calculator applies the official FERS formula to give you an annual pension estimate and a monthly breakdown, helping you plan for retirement with more confidence.
🛠 How to Use the FERS Calculator
Using our calculator is quick and straightforward. Here’s a step-by-step guide:
- Enter Your High-3 Salary
- This is the average of your highest-paid three consecutive years.
- Example: If your highest three years averaged $85,000, enter
85000.
- Enter Your Years of Service
- This is the total number of creditable years you worked in federal service.
- Example: If you’ve worked for 28 years, enter
28.
- Enter Your Retirement Age
- This is the age at which you plan to retire.
- Example: If you plan to retire at age 62, enter
62.
- Click “Calculate”
- The tool will instantly display your annual pension and monthly pension.
- Click “Reset” if you want to enter new values and recalculate.
📊 Example FERS Pension Calculation
Let’s walk through an example to see how the calculator works:
- High-3 Average Salary: $90,000
- Years of Service: 25
- Retirement Age: 62
👉 Since the employee is 62 or older with at least 20 years of service, the multiplier is 1.1% (0.011).
Formula:
Annual Pension = High-3 × Years of Service × Multiplier
Annual Pension = $90,000 × 25 × 0.011
Annual Pension = $24,750 per year
Monthly Pension = $24,750 ÷ 12 = $2,062.50 per month
This gives the federal employee a clear estimate of their retirement income.

⚖️ How FERS Pension is Calculated
The FERS pension formula is based on two main rules:
- General Formula (Age < 62 or Service < 20 years):
- Annual Pension = High-3 × Years of Service × 1% (0.01)
- Enhanced Formula (Age ≥ 62 and Service ≥ 20 years):
- Annual Pension = High-3 × Years of Service × 1.1% (0.011)
This small increase can make a big difference for employees who meet the eligibility requirements.
