    Introduction

    This FERS Retirement Calculator helps federal employees estimate their pension under the Federal Employees Retirement System (FERS). Enter your date of birth, service dates, High-3 salary, and sick leave hours to get a quick estimate of your monthly and annual pension. The calculator also checks which retirement types you qualify for, applies the correct multiplier (1.0% or 1.1%), and accounts for survivor benefit deductions and early retirement penalties.

    Your FERS pension is one of three parts of federal retirement income, along with Social Security and the Thrift Savings Plan (TSP).1 Knowing your estimated pension amount helps you plan ahead and decide when to retire. Use this tool to see how changes in your retirement date, sick leave balance, or survivor benefit election affect your final pension.

    How to Use Our FERS Retirement Calculator

    Enter your federal employment details below to estimate your FERS pension. The calculator will show your gross and net annual pension, monthly payments, eligibility status, and a full step-by-step breakdown of how your benefit is computed.

    Date of Birth: Enter the date you were born. This sets your Minimum Retirement Age (MRA), which determines when you can first retire under FERS rules.

    Retirement Service Computation Date (RSCD): Enter your RSCD, not your hire date. Your RSCD adjusts for breaks in service, part-time work, and military buybacks. You can find this date on your SF-50 or by asking your HR office.

    Projected Retirement Date: Pick the future date you plan to retire. This must be after both today's date and your RSCD.

    Retirement Type: Choose the type of retirement you expect to use. Options include Regular Retirement, MRA+10 (with or without an early penalty), VERA, and Discontinued Service Retirement.

    Unused Sick Leave (Hours): Enter the number of sick leave hours you expect to have when you retire. The calculator converts these hours into extra service credit at a rate of 2,087 hours per year.

    Prior Military Service: Select "Yes" if you served in the military. If you did, enter the years and months you served, whether you receive military retired pay, whether that retired pay is based on a combat-related disability or is reserve retired pay, and whether you have paid the military deposit (buyback). Military service after 1956 counts toward your FERS pension only if you pay the deposit, and if you receive military retired pay it counts only when that pay is based on a combat-related disability or is reserve retired pay.7

    High-3 Average Salary: Enter the average of your three highest-paid consecutive years of base pay. Include basic pay and locality pay,8 but not overtime or bonuses.2 For most federal employees the High-3 is the final three years of service, though an earlier period counts if basic pay was higher then.2

    Marital Status: Select "Married" or "Not Married." Married employees are automatically set to the 50% survivor benefit by default, as required by OPM unless your spouse consents to a waiver.2

    Survivor Benefit Election: Choose the survivor benefit level for your spouse. The 50% election reduces your pension by 10%.2 The 25% election reduces it by 5%.2 Choosing "No Survivor Benefit" means no reduction, but your spouse will not receive a continuing pension after your death.

    What Is the FERS Retirement Calculator?

    This calculator estimates your federal pension under the Federal Employees Retirement System (FERS). FERS took effect on January 1, 1987, and new federal civilian employees with retirement coverage have been covered by it since then.1 If you work for the federal government, your FERS pension is one of three parts of your retirement income. The other two parts are Social Security and the Thrift Savings Plan (TSP).1

    How Your FERS Pension Is Calculated

    Your FERS pension is based on a simple formula: High-3 Average Salary × Years of Creditable Service × Multiplier. Your High-3 is the average of your highest-paid three consecutive years of base pay.2 Creditable service is how long you worked for the federal government, plus any military service you bought back and unused sick leave. The multiplier is either 1% or 1.1%. You get the higher 1.1% rate if you retire at age 62 or older with at least 20 years of service.2

    When Can You Retire Under FERS?

    FERS has several retirement types, each with its own age and service rules:

    • Regular Retirement: Age 62 with 5 years of service, age 60 with 20 years, or your Minimum Retirement Age (MRA) with 30 years.3
    • MRA+10: Your MRA with at least 10 years of service. If you retire before age 62 under this option, your pension is reduced by 5% for each year you are under 62, unless you have 30 years of service, or 20 years with your annuity starting at age 60 or later.2
    • VERA (Early Out): Age 50 with 20 years, or any age with 25 years.4 Your agency must offer this option.4
    • DSR (Discontinued Service): Same age and service rules as VERA, but applies when your job is eliminated or you face involuntary separation.4

    Your Minimum Retirement Age (MRA) depends on your birth year. It ranges from 55 to 57.3 People born in 1970 or later have an MRA of 57.3

    Key Terms You Should Know

    Your Retirement Service Computation Date (RSCD) is not the same as your hire date. It is adjusted for breaks in service, part-time work, and military buybacks. This date sets how many years of creditable service you have. Unused sick leave is added to your service time when your pension is calculated. Every 2,087 hours of sick leave equals one extra year of service credit. Sick leave counts toward computing your annuity only, not toward eligibility,5 so it does not help you meet the 20-year requirement for the 1.1% multiplier.

    Survivor Benefits and Your Pension

    If you are married, your pension automatically includes a 50% survivor benefit for your spouse. This means your spouse would receive 50% of your unreduced pension after you pass away.6 In return, your pension is reduced by 10% while you are alive.2 You can choose a 25% survivor benefit instead, which reduces your pension by 5%,2 but your spouse must give notarized consent to that election.4 You may also waive the survivor benefit entirely, but your spouse must agree to that in writing.6

    Military Service and Your FERS Pension

    If you served in the military, that time can count toward your federal pension. Military service performed before 1957 counts without a deposit, but service after 1956 counts only if you pay the military deposit (buyback).7 If you are awarded military retired pay, the military service counts only when that retired pay is based on a service-connected disability incurred in combat or caused by an instrumentality of war, or is reserve retired pay.7

    Frequently asked questions

    What is the FERS retirement formula?

    The FERS pension formula is High-3 Average Salary × Years of Creditable Service × Multiplier. The multiplier is 1% for most retirees. It increases to 1.1% if you retire at age 62 or older with at least 20 years of creditable service.2

    What is my Minimum Retirement Age (MRA)?

    Your MRA depends on the year you were born. If you were born before 1948, your MRA is 55. If you were born between 1948 and 1952, it rises in two-month steps from 55 and 2 months to 55 and 10 months.3 For birth years 1953 through 1964, the MRA is 56.3 From 1965 to 1969, it rises again in two-month steps. If you were born in 1970 or later, your MRA is 57.3 This calculator figures out your MRA automatically from your date of birth.

    Where do I find my Retirement Service Computation Date (RSCD)?

    Your RSCD is listed on your SF-50 (Notification of Personnel Action). You can also ask your agency's human resources office. Do not use your hire date. The RSCD adjusts for breaks in service, part-time work, and military deposit payments.

    Does sick leave count toward the 20-year requirement for the 1.1% multiplier?

    No. Unused sick leave adds to your total creditable service for the pension calculation only, not for eligibility.5 It does not count toward the 20-year service threshold needed for the 1.1% enhanced multiplier. Only actual federal service time and creditable military service count toward that threshold.

    How is unused sick leave converted into service credit?

    OPM converts sick leave at a rate of 2,087 hours per year. For example, if you have 1,044 hours of unused sick leave, that equals about 6 months of extra service credit added to your pension calculation.

    How does the MRA+10 early retirement penalty work?

    If you retire under MRA+10 before age 62, your pension is reduced by 5% for each full year you are under 62. OPM calculates this as 5/12 of 1% for each full month under age 62.2 For example, if you retire 3 years (36 months) before turning 62, your pension is cut by 15%. The reduction does not apply if you have 30 years of service, or 20 years with your annuity starting at age 60 or later.2 Postponing the start of your annuity reduces or eliminates it.2

    What is the High-3 average salary?

    Your High-3 is the average of your three highest consecutive years of base pay. For most federal employees, this is the last three years before retirement.2 It includes locality pay, which counts as basic pay for retirement,8 but does not include overtime or bonuses.2

    Can I waive the survivor benefit if I am married?

    Yes, but your spouse must give written consent.6 OPM automatically applies the 50% survivor benefit for married retirees. If you want to reduce it to 25% or waive it entirely, your spouse must give notarized consent.4

    What is the difference between VERA and regular retirement?

    VERA (Voluntary Early Retirement Authority) lets you retire earlier than normal rules allow. It requires age 50 with 20 years of service, or any age with 25 years.4 However, your agency must offer VERA.4 You cannot choose it on your own. Regular retirement has its own age and service combinations and is always available once you meet the requirements.

    Is the pension estimate before or after taxes?

    The amounts shown are before federal and state income taxes. Your FERS pension is taxable income. The actual amount you take home will be lower after taxes. Tax rates depend on your total income, filing status, and state of residence.

    Do I need to complete a military deposit to get credit for military service?

    Yes. Under FERS, military service after 1956 counts toward your pension only if you pay the military deposit (buyback).7 If you are awarded military retired pay, the service counts only when that retired pay is based on a service-connected disability incurred in combat or caused by an instrumentality of war, or is reserve retired pay.7

    What happens if I retire at age 62 with less than 20 years of service?

    You still qualify for regular retirement if you have at least 5 years of creditable service.3 However, your multiplier will be 1%, not the enhanced 1.1%. You need both age 62 and 20 years of service to earn the higher rate.2

    Is the survivor benefit deduction applied before or after the early retirement penalty?

    The early retirement penalty (age reduction) is applied first. Then the survivor benefit deduction is calculated on the already-reduced amount. This means the survivor deduction is smaller than it would be if applied to the full gross pension.

    Can I defer my MRA+10 pension to avoid the penalty?

    Yes. If you retire under MRA+10, you can postpone the start of your annuity to any date up to just before your 62nd birthday, and the longer you wait, the smaller the age reduction.4 If you have 20 years of service and your annuity starts at age 60, the reduction is eliminated.4 You will not receive payments during the postponement. You can keep your health coverage for up to 18 months by paying the full premium plus a 2% administrative charge, and you can reenroll in FEHB when your annuity begins if you had FEHB coverage for the 5 years before you separated.4

    Does part-time service affect my pension?

    Yes. OPM figures your High-3 using the full-time rates of basic pay for your position, then prorates the basic annuity by a proration factor that reflects your part-time schedule.9 That proration can lower your pension compared to full-time service over the same number of years.

    What is Discontinued Service Retirement (DSR)?

    DSR applies when your position is eliminated or you are involuntarily separated through no fault of your own.4 The eligibility rules are the same as VERA: age 50 with 20 years of service, or any age with 25 years.4 Unlike VERA, DSR does not require your agency to offer it. It is triggered by the involuntary action itself.

    Does locality pay count in the High-3 calculation?

    Yes. Your High-3 includes basic pay plus locality pay.8 It does not include overtime or bonuses, but it does include pay increases subject to retirement deductions, such as shift rates.2 Locality pay is considered part of your base pay for FERS pension purposes.8

    What if I have a CSRS component from prior service?

    This calculator is designed for FERS-only retirements. If you have a CSRS (Civil Service Retirement System) component from earlier federal service, your pension is calculated differently and may use a blended formula.2 Contact your HR office for a dual-coverage estimate.
