FERS Benefit Calculator
✅ What Is the FERS Benefit Calculator?
The FERS Benefit Calculator is an interactive tool that estimates your retirement pension under the Federal Employees Retirement System.
It is based on the official FERS pension formula:
- 1% × High-3 Average Salary × Years of Service
- Or 1.1% × High-3 Average Salary × Years of Service (if retiring at age 62 or older with at least 20 years of service).
This calculator gives you both:
- Annual Pension Estimate
- Monthly Pension Estimate
By using it, you get a clear picture of how much income you can expect to receive after retirement.
🛠️ How to Use the FERS Benefit Calculator
Using the calculator is simple and requires only three inputs:

- Example: If you’ve worked for 25 years, enter 25.
- Retirement Age
