What FERS Is and How It Pays You
FERS — the Federal Employees Retirement System — is the pension program for most federal civilian employees hired after 1983. It works by taking money from your paychecks during your working years, matching some of that money, and then paying you a monthly amount for life once you retire. The amount you receive depends on how long you worked, how much you earned, and the age at which you stop working.
FERS is actually three separate pieces working together: a basic pension, Social Security contributions, and a savings account called the Thrift Savings Plan (TSP). Understanding how each piece works helps you know what to expect when you retire.
You do not have to do anything to be in FERS if you are a federal employee — you are automatically enrolled. Contributions come straight from your paycheck, and your agency matches part of what you contribute. The system is managed by the Office of Personnel Management (OPM), which handles all the calculations and sends out your monthly check.
Key Takeaways
- FERS has three parts: a basic pension based on your years of service and salary, Social Security contributions, and the Thrift Savings Plan, which is your own retirement savings account.
- Your basic pension payment is calculated using a formula that multiplies your years of service by a percentage of your average salary over your highest-earning three years.
- You can retire as early as age 57 with 30 years of service, or at age 62 with 5 years of service, but retiring earlier means a smaller monthly payment.
- FERS contributions are taken from your paycheck automatically, and your agency contributes a matching amount that goes into your TSP account.
- Once you start receiving your FERS pension, the payment continues for your entire life, and your surviving spouse or children may receive a portion if you choose that option.
How Your Basic Pension Payment Is Calculated
Your monthly FERS pension is based on a straightforward formula: years of service × 1% × your average salary. The "average salary" part is your highest three consecutive years of earnings. So if you worked 30 years and your average high-three salary was $60,000, your annual pension would be 30 × 1% × $60,000 = $18,000 per year, or $1,500 per month.
The 1% multiplier is the standard rate for most federal employees. Some employees in special occupations — such as law enforcement officers, firefighters, or air traffic controllers — use a higher multiplier of 1.7% instead, which results in a larger pension.
Your "high-three" average is recalculated using your actual earnings records, so it reflects raises, bonuses, and any overtime you received during those three years. Part-time work, leave without pay, or periods when you were not earning your full salary will lower this average.
When You Can Retire and How It Affects Your Payment
FERS has two main retirement windows. The first is age 57 with 30 years of service. If you meet this combination, you can retire immediately and receive your full calculated pension with no reduction. The second is age 62 with 5 years of service. You can also retire at any age if you have 30 years of service, but your pension will be reduced by 5% for each year you are under age 62.
If you retire before age 62 with fewer than 30 years of service, your pension is reduced permanently. For example, retiring at age 55 with 25 years of service means your pension is cut by 35% (7 years × 5%) for the rest of your life. This reduction never goes away, even after you turn 62.
The reduction is designed to account for the fact that you will receive payments for a longer period. If you can wait until you meet one of the unreduced retirement windows, your lifetime income is usually higher, even though you receive fewer total checks.
The Three Parts of FERS: Pension, Social Security, and TSP
Your FERS pension is only one piece of your retirement income. The second piece is Social Security. FERS employees pay into Social Security just like private-sector workers, so you will receive a Social Security benefit when you turn 62 or 67 (depending on your birth year). This is separate from your FERS pension and is managed by the Social Security Administration, not OPM.
The third piece is the Thrift Savings Plan (TSP), which is a retirement savings account similar to a 401(k). Your agency automatically contributes 1% of your salary to your TSP account. If you contribute your own money, your agency will match up to 4% of your salary. You control how this money is invested — you choose from different fund options — and you decide when and how much to withdraw after you retire. Unlike your pension, which is may provide for life, your TSP balance depends on how well your investments perform.
Together, these three sources — your FERS pension, Social Security, and TSP withdrawals — make up your total retirement income. The FERS pension is the only part that is may provide and paid for life.
What Happens to Your Pension If You Leave Federal Service
If you leave your federal job before you are may be able to access to retire, you have options for what happens to your FERS contributions. If you have fewer than 5 years of service, you can withdraw your own contributions plus interest, but your agency's contributions go back to the government. If you have 5 or more years of service, you can leave your money in the FERS system and receive a deferred pension starting at age 62, even if you never work for the federal government again.
A deferred pension is calculated the same way as an immediate pension — using your years of service and high-three average — but you do not receive any payments until you reach age 62. This option is useful if you leave federal service but want to preserve your retirement benefit.
You can also roll your TSP balance into an Individual Retirement Account (IRA) or another employer's retirement plan if you leave. Your FERS pension itself cannot be rolled over — it stays in the FERS system until you are ready to receive it.
Survivor Benefits and What Your Family Receives
When you retire, you choose how your FERS pension will be paid out. The standard option is a single life annuity, which pays you the full amount for your entire life, but stops when you die. Your family receives nothing after that.
Alternatively, you can choose a survivor benefit option, which reduces your monthly payment but guarantees that your spouse or children will receive a portion of your pension if you die. The most common survivor option is a joint and survivor annuity, which pays you a reduced amount during your lifetime, and then pays your surviving spouse a percentage of that amount (usually 50% or 75%) for the rest of their life.
If you have children under age 18 (or 22 if they are in school full-time), they may also receive a benefit if you die. The exact amount depends on which survivor option you chose and how many may be able to access family members you have. You must make your survivor benefit choice before you retire — you cannot change it afterward.
How Taxes and Cost-of-Living Adjustments Work
Your FERS pension is subject to federal income tax. You can request that OPM withhold taxes from your monthly check, or you can pay taxes when you file your annual return. State and local taxes on your pension depend on where you live — some states do not tax pensions at all, while others tax them fully.
Every year in December, FERS pensions receive a cost-of-living adjustment (COLA) if inflation has occurred. This adjustment is tied to the Consumer Price Index and is designed to help your pension keep pace with rising prices. The COLA is automatic — you do not have to request it — and it applies to all retirees, including those who retired many years ago.
The COLA amount varies from year to year. In some years it is 2% or 3%, and in years with very low inflation it may be less than 1%. In rare years with deflation, there is no COLA increase, but your pension also does not decrease.
Frequently Asked Questions
Can I work another job while receiving my FERS pension?
Yes, you can work in the private sector or for a non-federal employer without any restrictions on your FERS pension. However, if you return to federal employment, your FERS pension may be suspended while you are working, depending on your age and years of service. Contact OPM to understand how returning to federal work would affect your specific situation.
What if I become disabled before I can retire?
FERS has a disability retirement program. If you become unable to work due to injury or illness, you may receive a disability benefit even if you have not reached normal retirement age. The amount is typically calculated as 60% of your high-three average salary, or your regular FERS pension amount if that is higher. You must apply through OPM and provide medical documentation.
How do I know what my high-three average salary is?
Your high-three average is shown on your annual Leave and Earnings Statement (LES), which your agency provides each pay period. You can also contact OPM's retirement services or log into your federal employee account to view your estimated retirement benefit. OPM can provide a detailed breakdown of how your high-three is calculated.
What happens to my FERS pension if I move to another country?
You can receive your FERS pension while living outside the United States. OPM will continue to send your monthly payment, and your COLA adjustments will continue as well. However, you may need to complete periodic certifications to confirm you are still alive, and some countries may have tax implications for receiving a U.S. federal pension.
Can I receive my FERS pension and Social Security at the same time?
Yes. Your FERS pension and Social Security are separate programs, so you can receive both. However, if you did not pay into Social Security for enough years, a provision called the Government Pension Offset (GPO) may reduce your Social Security spousal or survivor benefits. This does not affect your own Social Security benefit based on your own earnings record.
