FERS Pension Calculator
Planning for retirement as a federal employee requires understanding how your pension is calculated under the Federal Employees Retirement System (FERS). Our FERS Pension Calculator is a powerful, easy-to-use online tool designed to help you quickly estimate your annual and monthly retirement annuity based on your salary, years of service, age, unused sick leave, and survivor benefit election.
Whether you’re approaching retirement or just starting your federal career, this calculator gives you a clear picture of your potential income so you can plan confidently.
What Is FERS?
The Federal Employees Retirement System (FERS) is the retirement plan for U.S. civilian federal employees. It provides retirement income through three main components:
- Basic Benefit Plan (pension)
- Social Security
- Thrift Savings Plan (TSP)
This calculator focuses specifically on the FERS Basic Benefit Plan, which provides a defined monthly annuity based on a formula involving your salary and service history.
How the FERS Pension Is Calculated
Your FERS pension is generally calculated using this formula:
High-3 Average Salary × Years of Creditable Service × Multiplier
Key Factors Explained
1. High-3 Average Salary
Your “High-3” is the highest average basic pay you earned during any three consecutive years of federal service. This usually occurs in your final years of employment.
2. Years of Creditable Service
This includes:
- Total years and months of federal service
- Converted unused sick leave (added as additional service credit)
3. Retirement Age
Your age at retirement can affect your pension multiplier. If you retire at:
- Age 62 or older with at least 20 years of service → 1.1% multiplier
- Otherwise → 1% multiplier
4. Survivor Benefit Election
You may choose to provide a survivor benefit to your spouse, which reduces your pension:
- Full survivor benefit → 10% reduction
- Partial survivor benefit → 5% reduction
- No survivor benefit → No reduction
Our calculator automatically factors this into your final estimate.

Example FERS Pension Calculation
Let’s look at a practical example:
- High-3 Salary: $100,000
- Years of Service: 25
- Retirement Age: 62
- Unused Sick Leave: 1,000 hours
- Survivor Benefit: Full
Step-by-Step Breakdown
- Convert sick leave:
1,000 ÷ 2,087 = 0.48 years - Total service:
25 + 0.48 = 25.48 years - Multiplier:
Age 62 + 20+ years → 1.1% - Gross Annual Pension:
$100,000 × 25.48 × 0.011 = $28,028 - Survivor Reduction (10%):
$2,802.80 - Net Annual Pension:
$25,225.20 - Monthly Pension:
$2,102.10
This gives you a clear estimate of what to expect in retirement income.
