Federal Employees Retirement System Calculator
Planning for retirement is one of the most crucial financial decisions in life—especially for federal employees under the Federal Employees Retirement System (FERS). Knowing your estimated pension can help you set goals, adjust your savings strategy, and retire with confidence. That’s why we created this FERS Retirement Calculator—a simple, free tool that provides an accurate pension estimate based on your salary, years of service, and retirement age.
Whether you’re a new federal employee or just a few years away from retirement, this tool is designed to give you clarity and control over your financial future.
What Is the FERS Calculator?
The FERS Calculator is a browser-based tool that helps federal employees estimate their annual pension under the Federal Employees Retirement System. It uses key inputs—your high-3 average salary, years and months of service, and retirement age—to compute your pension based on FERS formulas.
With a single click, it provides a quick snapshot of what your FERS pension will look like in retirement.
How to Use the FERS Pension Calculator (Step-by-Step)
Using the FERS Retirement Calculator is straightforward. Here’s a quick guide to help you get an accurate estimate:
- High-3 Average Salary ($):
Enter the average of your highest three consecutive years of basic pay. This does not include bonuses, overtime, or allowances. - Years of Service:
Input the total number of full years you have worked as a federal employee. - Additional Months of Service:
Enter any additional months beyond full years (0–11). These will be converted into fractions of a year. - Retirement Age:
Provide your expected retirement age (between 50 and 70). This affects your pension multiplier. - Click “Calculate”:
Press the Calculate button. Your Annual Pension Estimate will appear below the form. - Reset Option:
To clear the form and start over, click the Reset button.
How the Calculation Works
The tool follows official FERS pension formulas, which generally include a multiplier of 1% of your high-3 salary for each year of service. However, if you retire at age 62 or older with at least 20 years of service, the multiplier increases to 1.1%, giving you a higher annual pension.
Formula:
javaCopyEditFERS Annual Pension = High-3 Salary × Years of Service × Multiplier
- Standard Multiplier: 1.0%
- Enhanced Multiplier: 1.1% (if age ≥ 62 and service ≥ 20 years)
Example Scenarios
Let’s look at some realistic use cases to see how the calculator can help:
Example 1: Retiring at 60 with 25 Years of Service
- High-3 Salary: $85,000
- Years: 25
- Months: 0
- Age: 60
Calculation:
Multiplier = 1.0%
Pension = $85,000 × 25 × 0.01 = $21,250/year
Example 2: Retiring at 62 with 20 Years of Service
- High-3 Salary: $100,000
- Years: 20
- Months: 0
- Age: 62
Calculation:
Multiplier = 1.1%
Pension = $100,000 × 20 × 0.011 = $22,000/year
