Estimated Annual FERS Pension:
Understanding Your FERS Pension Estimate
The Federal Employees Retirement System (FERS) is a defined benefit retirement plan for federal employees. Calculating your estimated pension can help you plan for your financial future. This calculator provides an estimate based on key factors, but it's important to remember that your official pension amount will be determined by your agency's retirement system upon your actual retirement.
How FERS Pensions are Calculated
The basic FERS pension formula depends on your years of creditable service and your average of the three highest years of basic pay (often referred to as the "High-3" average salary). The multiplier used in the calculation varies based on your age and service at the time of retirement.
Standard Retirement Multiplier:
For those retiring at their Normal Retirement Age (NRA), which is typically 62 with at least 5 years of service, or at age 60 with at least 20 years of service, the multiplier is 1%.
Early Retirement Multiplier:
If you retire before your NRA under specific early retirement provisions (like voluntary separation, often requiring at least 20 years of service and being between ages 50-55, or other special provisions), the multiplier is reduced. For most early retirements, including voluntary separation, the multiplier is 1%.
However, a common scenario for FERS retirement is retiring at age 60 or later with at least 20 years of service, which still uses the 1% multiplier. Retiring between ages 56 and 59 with at least 20 years of service uses a 1% multiplier. For those retiring before age 56 and 8 months with at least 20 years of service, the multiplier is 1%.
FERS Special Retirement Supplement (SRS):
This calculator does NOT include the FERS Special Retirement Supplement (SRS), which is a separate benefit that can approximate Social Security benefits for retirees between their retirement date and age 62. The SRS calculation is complex and depends on many factors not included here.
FERS Retirement Age Scenarios:
Minimum Retirement Age (MRA) with 30+ Years of Service: Retirees can take their pension with no reduction at their MRA (which is gradually increasing to 67) if they have at least 30 years of service. The multiplier is 1%.
Age 60 with 20+ Years of Service: Retirees can take their pension with no reduction at age 60 if they have at least 20 years of service. The multiplier is 1%.
Age 62 with 5+ Years of Service: This is the most common standard retirement. The multiplier is 1%.
Age 56 and 8 months with 20+ Years of Service: For retirements occurring between MRA and age 60 (but not meeting the age 60/20yr criteria), the multiplier is 1%.
Voluntary Early Retirement (VER): Typically requires at least 20 years of service and an age between 50 and 55. The multiplier is 1%. Some CSRS employees might retire with a higher multiplier at an earlier age, but for FERS, it generally remains 1% for these early outs.
Using This Calculator:
To get your estimated annual FERS pension:
Years of Creditable Service: Enter the total number of full years and any partial years you have worked in federal service that are considered creditable for FERS retirement.
High-3 Average Salary: Find your average basic pay over the highest-paid three consecutive years of your federal career.
Retirement Age: Select the age at which you plan to retire. The options reflect common FERS retirement milestones. If you are retiring under a specific early out like Voluntary Separation, select that option.
Voluntary Separation: Indicate if your retirement falls under voluntary early retirement provisions. If 'Yes', you will be prompted to enter your specific years of service for that condition.
The calculator will then apply the appropriate multiplier to your High-3 average salary, multiplied by your years of service, to give you an estimated annual pension amount.

It is based on general FERS formulas and may not account for all unique circumstances, such as specific agency contributions, buy-back programs, or changes in law.
