Fers Retirment Calculator
For federal employees, planning for retirement under the Federal Employees Retirement System (FERS) can feel overwhelming. With several components like the High-3 average salary, years of service, and age playing key roles in determining pension eligibility and income, it’s important to get an accurate estimate of your benefits.
That’s where our FERS Retirement Calculator comes in. This user-friendly tool helps federal workers project their annual FERS pension based on a few simple inputs. Whether you’re nearing retirement or just planning ahead, this calculator gives you a clearer picture of your financial future.
What is the FERS Retirement Calculator?
The FERS Retirement Calculator is an online tool that estimates your annual basic pension benefit under the FERS system. The formula behind the tool reflects the standard FERS pension calculation:
Pension = High-3 Salary × Years of Service × Multiplier
This calculator is ideal for current federal employees (including postal workers, law enforcement, and military service members with FERS creditable time) looking to estimate their immediate or deferred retirement benefit.
The Tool Uses:
- Your High-3 salary (average of your highest-paid consecutive 3 years)
- Your total years and months of creditable federal service
- Your age at retirement
- Applicable pension multiplier (1% or 1.1% depending on retirement age and service years)
How to Use the FERS Retirement Calculator
Follow these simple steps to use the calculator effectively:
1. Enter Your High-3 Average Salary
This is your highest average basic pay earned during any consecutive 3-year period. Exclude bonuses and overtime.
2. Input Your Years of Service
This is the full number of years you’ve worked in a FERS-covered position.
3. Add Additional Months of Service
If you haven’t completed a full year, enter the number of extra months (0–11) here. The calculator will automatically convert months into a fraction of a year.
4. Enter Your Retirement Age
This helps determine whether you qualify for the higher multiplier (1.1%) available to employees age 62+ with at least 20 years of service.
5. Click “Calculate”
The calculator will instantly display your estimated annual FERS pension in dollars.
6. Click “Reset” to Clear the Form
Start over anytime by clicking the reset button.
Example: Federal Pension Estimate
Let’s walk through a sample calculation:
Input:
- High-3 Salary: $90,000
- Years of Service: 25
- Additional Months: 6
- Retirement Age: 63
Calculation:
- Total Service: 25.5 years
- Multiplier: 1.1% (because age ≥ 62 with ≥ 20 years)
- Pension = $90,000 × 25.5 × 0.011 = $25,245.00 per year
Estimated Annual FERS Pension: $25,245.00
This would be your lifetime annuity before taxes and other potential deductions (like survivor benefits or FEHB premiums).
