There are many things to consider when determining your FERS retirement benefits [2]. If you meet certain requirements, you will receive a Special Retirement Supplement which is paid until you reach age 62. This supplement is similar to the Social Security benefit [3] earned while you were employed by the Federal government. However, since the formula for the Special Supplement assumes a working life of 40 years, each year of FERS service is worth one-fortieth of the estimated Social Security benefit. The FERS Supplement is often significantly less than the Social Security benefit you will receive at age 62. The supplement ends at age 62 even if you elect to wait to apply for Social Security benefits.

Steps to Computing the Annuity Supplement
The FERS supplement provides a level of income before age 62 similar to what the retiree will receive at age 62 as part of a Social Security benefit, if eligible for Social Security at that age. The formula for calculating the supplement is complex and they use your complete creditable service earnings history to determine your benefit.
- A complete earnings history is compiled using the employee’s basic civil service pay under FERS and deemed wages for years of employment.
- The earnings history is updated for inflation.
- The supplement is calculated using the same formula that Social Security uses to compute a Social Security benefit, including the maximum reduction for early retirement under Social Security.
- The result of the previous step is multiplied by a fraction to approximate the proportion of a full career Social Security benefit earned under FERS.

You may be eligible for a Special Retirement Supplement if you retire:
- After the Minimum Retirement Age (MRA) [2] with 30 years of service;
- At age 60 with 20 years of service; or
- Upon involuntary or early voluntary retirement [6] (age 50 with 20 years of service, or at any age with 25 years of service) after OPM determines that your agency is undergoing a major reorganization, reduction-in-force (RIF) or transfer of function. You will not receive the Special Retirement Supplement until you reach your MRA.
If you transfer to the Federal Employees Retirement System (FERS) from the Civil Service Retirement System (CSRS), you must have at least one full calendar year of FERS-covered service to qualify for the supplement.
Retirees that have earnings from wages or self-employment that exceed the Social Security annual exempt amount ($17,640 in 2019) will see their Retirement Supplement either reduced or stopped.
