Navigating the Federal Employees Retirement System (FERS) can be challenging. Many workers have reached out to our law firm wondering how their annuities are calculated, what factors are important, and what could lead to a reduction or deduction in retirement benefits.
Our federal employee rights attorneys would like to go over some of the basics when calculating FERS retirement benefits. We’ll also note how your average salary, retirement age, and nature of your federal employment could affect how much you receive when you retire.
If you have any questions about the FERS or need to speak with a lawyer about a problem with your federal retirement benefits, The Bell Law Group can help. For a free, confidential no-obligation consultation, contact our employment law attorneys today.
Key Takeaways:
- When calculating federal retirement benefits, the three key elements are your high-3 average salary, your years of federal service, and the age you decide to retire. You may also have an adjustment to account for inflation/changes in the cost of living.
- The basic annuity formulas for FERS benefits are Your High-3 Salary × 1% × Your Years of Creditable Service or (depending on age and service) Your High-3 Salary × 1.1% × Your Creditable Years of Service.
- Federal employees in high-risk or physically demanding roles may qualify for special retirement provisions, which includes earlier retirement eligibility, enhanced pension calculations, and mandatory retirement ages.
- Your retirement benefits may be reduced if you opt for early retirement with just 10 years of service (MRA+10) or you opt for full or partial survivor benefits for your spouse.
- If the U.S. Office of Personnel Management (OPM) makes a mistake while calculating your retirement benefits, be sure to contact the OPM directly, note the nature of the error, and provide copies of any supporting documentation. You should also hire a lawyer if you need help with reconsideration or an appeal.
The Three Core Elements of the FERS Basic Annuity Formula
To calculate your FERS retirement, the OPM will take three key elements into consideration:
- Your High-3 Average Salary: This refers to your highest average basic pay as a federal employee during a period of three consecutive years.
- Your Total Years of Creditable Service: This refers to the number of years and months that you have worked for the federal government.
- Your Age at the Time of Retirement: This refers to your age when you decide that it’s time to retire.
We recommend reading through the OPM’s guide through the federal retirement process if you are nearing retirement age. Their resource provides solid insight into how to prepare for retirement, what to expect, and potential delays and setbacks in the process.
Retirement Benefits and Cost-of-Living Adjustments (COLAs)
In addition to the above three elements, your retirement benefits may be adjusted to keep up with the pace of inflation. This is known as a Cost-of-Living Adjustment (COLA). When a COLA is payable, it takes effect in December of each year, with beneficiaries receiving the adjustment payment the following month (January).
The COLA can vary each year and is determined by changes in the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W).
What You Should Know About Your High-3 Average Salary
Your high-3 average salary is the highest average basic pay you received during any consecutive three-year period. This includes your base salary, locality pay to offset a higher cost of living in your area, and other forms of pay related to your basic pay in your role.
Your high-3 does not have to be your last three years of service before you apply for retirement. This is important for any federal employees who shifted to a lower-paying position or had a reduction in their basic pay in the years leading up to retirement.
Do Overtime Pay or Bonuses Count Toward My High-3 Federal Salary Calculation?
No. Overtime, bonuses, awards, and any travel per diems are not included in your high-3 average salary. Your high-3 average salary is focused solely on your base salary.
What You Should Know About Your Total Years of Creditable Service
Your creditable years of service apply to any positions covered by the FERS or the older Civil Service Retirement System (CSRS). Your years of creditable service may include:
- Time in civilian federal positions covered by the FERS or CSRS
- Certain periods of military service
- Certain periods of leave without pay (LWOP)
The Sick Leave Conversion Trick
If you have any unused sick leave from your time in federal service, it can be used to increase the amount of your annuity. This unused sick leave is considered creditable service for these calculations once you qualify for retirement.
However, unused sick leave cannot be used as a substitute for creditable service allowing for an earlier retirement.
For example, say that your Minimum Retirement Age (MRA) is 57 years old as long as you have completed 30 years of creditable service. If you are 57 years old and have 29 years of creditable service, you cannot apply that year of unused sick leave to your years of service.
What You Should Know About Your Age at the Time of Retirement
For anyone born after 1970, the Minimum Retirement Age is 57 years old. However, to retire at age 57, you need to have completed 30 years of creditable retirement.
For those who reach 60 years old, you can retire if you have 20 years of creditable service.
For anyone 62 years old, you need just 5 years of creditable service.
Pension Multiplier: The 1% vs. 1.1% Critical Age Milestone
Your age at the time of retirement affects your pension multiplier.
- If you retire before age 62, your pension formula = Your high-3 salary × 1% × Your years of service
- If you retire at age 62 but with less than 20 years of service, your pension formula = Your high-3 salary × 1% × Your years of service
- If you retire at age 62 or older with at least 20 years of service, your pension formula = Your high-3 salary × 1.1% × Your years of service
Don’t take that extra 0.1% for granted. It may not seem like much on its own, but it can mean thousands of dollars in the long run during retirement.
Special Retirement Coverage (SRC): Provisions for High-Risk and Physically Demanding Roles
There are enhanced retirement benefits and rules for federal employees who are in high-risk or physically demanding positions.
These employees will often contribute more to the retirement system during federal service in exchange for enhanced pension calculations and earlier eligibility for retirement.
Who Is Eligible for Special Retirement Coverage?
According to the Defense Civilian Personnel Advisory Service (DCPAS), people eligible for SRC include:
- Federal law enforcement officers (LEOs)
- Federal firefighters
- Nuclear materials couriers
- Customs and Border Protection (CBP) officers
- Members of the Supreme Court Police
- Member of the Capitol Police
- Department of Defense (DOD) air traffic controllers
Key Benefits Associates with Special Retirement Coverage
Some of the key benefits associated with these special retirement provisions include:
- You Can Retire at an Earlier Age: Eligible federal workers with at least 20 of covered service can retire at age 50; if you have at least 25 years of covered service, you can retire at ay age.
- Your Pension Calculations Are Enhanced: Rather than standard calculations, eligible federal workers qualify for 1.7% of their high-3 average salary for the first 20 years of service PLUS 1% of their average high-3 salary for each year of service exceeding 20 years.
- You Have a Mandatory Age for Retirement: Given the physical demands of these roles, there may be a mandatory retirement age for these federal employees.
Reductions and Deductions for Federal Retirement Benefits
There are some notable factors that could lead to a reduction in FERS benefits.
Early Retirement: Minimum Age Requirement Plus 10 (MRA+10)
MRA+10 is an early retirement option. It allows federal workers to retire If you reach your minimum retirement age and have at least 10 years of creditable service (but less than 30 years of service).
However, under MRA+10, the OPM will reduce your benefits by 5% for each year you are younger than age 62. This can have a significant impact on how much you receive in federal retirement benefits.
FERS Retirement Survivor Benefits
After a federal retiree passes away, an eligible beneficiary can receive FERS survivor benefits. This is usually a spouse, though there are other eligible survivors.
Under FERS rules:
- A full survivor benefit would reduce your monthly annuity by 10%. After your death, your spouse would receive 50% of your total unreduced monthly annuity for life.
- A partial survivor benefit would reduce your monthly annuity by 5%. After your death, your spouse would receive 25% of your unreduced monthly annuity for life.
Common Deductions from Monthly Retirement Benefits
The following deductions will not reduce the total retirement benefits you’re eligible for, but they may alter how much you deposit each month:
- Federal income taxes
- State income taxes
- Federal Employees Health Benefits (FEHB)
- Federal Employees’ Group Life Insurance (FEGLI)
If you’ve gone through a divorce, you may also need to split federal retirement benefits with your spouse if ordered to do so by the court.
What About FERS Disability Retirement?
Federal disability retirement allows disabled public servants to retire early if they’ve fulfilled certain eligibility requirements. This differs from early retirement and deferred retirement.
For more information, we encourage you to read our 2026 guide to FERS disability retirement. The Bell Law Group is here to help with any issues you encounter while retiring from federal service.
What to Do When the OPM Makes a Mistake That Affects Retirement Benefits
If the OPM makes an error that affects your retirement eligibility or your benefits, you can have the matter reviewed and corrected when appropriate. Here are the steps you need to take if you notice an OPM mistake:
Identify the Specific Error(s) Made by the OPM
Note the exact error(s) in the OPM’s records or findings. Some common mistakes by the OPM may include:
- Incomplete paperwork or documentation
- Miscalculation of the high-3 average salary
- Incorrect years of creditable service
- Wrong cost-of-living adjustments (COLAs)
- Errors in FEHB or FEGLI enrollment
- Errors in survivor benefit elections
- Discrepancies in service records
Gather All Relevant Supporting Documents
Compile all relevant paperwork and filings related to your federal service and retirement. This may include:
- Relevant past correspondence with the OPM
- Relevant SF-50s (Notification of Personnel Action)
- Your application for retirement
- Military discharge papers
- Annuity statements
You may also want to contact the agency you work for/are retiring from. Your agency may be able to offer guidance for your situation and provide additional documentation.
We recommend reading our resource on what federal workers should do with SF-50s, as this could be helpful to federal employees at any stage of their career.
Contact the OPM About the Mistake
When you have your documents ready, contact the OPM directly (note the number for Retirement Services).
Explain the issue that has come up and provide copies of any supporting documents. For your personal records of this process, we recommend taking notes on:
- The date and time of any phone calls
- The names of OPM representatives you’ve spoken to
- Any confirmation numbers received
- Copies of all correspondence from the OPM
When Necessary, Request Formal Reconsideration or an Appeal
If the OPM does not correct the error or makes a decision that you do not agree with, you can file an appeal or reconsideration. Note that there may be a tight deadline you have to meet, so make sure to act promptly and be mindful of any dates or windows mentioned by the OPM.
