2027 FERS COLA: What the October 14 Announcement Means for Federal Retirees

The 2027 FERS COLA is 2.6% for eligible Federal Employees Retirement System (FERS) retirees age 62 and older. The Social Security Administration (SSA) announced a 3.6% cost-of-living adjustment (COLA) on October 14, 2026, and that figure drives the FERS number.
‍

The 2027 FERS COLA is the annual inflation adjustment that applies to eligible FERS annuities beginning with the January 2027 payment. A reduced statutory formula subtracts one percentage point from the Social Security COLA whenever the qualifying inflation increase exceeds 3%. Civil Service Retirement System (CSRS) annuitants receive the full 3.6% adjustment, while FERS annuitants often receive a reduced one.
‍

This article explains how OPM calculated the 2027 FERS COLA, who qualifies, and how it compares to the CSRS and Social Security adjustments. It also covers what factors can change the actual dollar amount a retiree sees, including proration, Medicare, and Federal Employees Health Benefits (FEHB) premiums.

Federal Employee Advisor Network, a retirement planning firm specializing in federal employee benefits, prepared this guide using figures confirmed by the SSA and the U.S. Office of Personnel Management (OPM).
‍

What Is the 2027 FERS COLA?
‍

The 2027 FERS COLA is a 2.6% increase to the basic annuity of eligible FERS retirees age 62 and older. It takes effect December 1, 2026, with the first higher payment issued in January 2027.
‍

Based on inflation figures the Bureau of Labor Statistics (BLS) released October 14, the 2027 cost-of-living adjustment is 3.6% for Social Security recipients and CSRS retirees. Under the statutory FERS COLA formula codified at 5 U.S.C. § 8462, a Social Security COLA above 3% translates into a FERS adjustment one percentage point lower.
‍

The 2.6% figure applies to the basic FERS annuity only. The basic annuity is the base monthly pension OPM calculates at retirement, before any survivor benefit election or insurance deductions.
‍

This base amount is the only portion that receives the annual COLA. The 2.6% does not apply to the FERS Special Retirement Supplement, which never receives a COLA.
‍

Not every eligible FERS retiree will see the full 2.6%. OPM applies proration rules to annuities paid for less than a full year.
‍

How the FERS “Diet COLA” Formula Produced 2.6%
‍

SSA set the 2027 Social Security COLA at 3.6%, based on the change in the third-quarter CPI-W average compared with the same quarter in the preceding year. Under the FERS COLA formula, that qualifying increase above 3% produces an adjustment one percentage point lower, yielding a 2.6% FERS COLA for 2027.
‍

OPM applies the following tiered formula under statute:

• If the qualifying CPI-W increase is 2% or less: FERS receives the full CPI-W increase.
• If the qualifying CPI-W increase is more than 2% but no more than 3%: FERS receives a flat 2%.
• If the qualifying CPI-W increase is more than 3%: FERS receives the CPI-W increase minus one percentage point.

Because the 2027 Social Security and CSRS COLA landed at 3.6%, the reduced FERS adjustment is 2.6%. The pattern also showed up in 2026, when CSRS received 2.8% but FERS received only 2.0%. That gap illustrates how the formula narrows the FERS raise whenever the qualifying CPI-W increase exceeds 2%, not only above 3%.
‍

Congress established FERS in 1986 as a retirement system with three main components: the basic FERS annuity, Social Security, and the Thrift Savings Plan (TSP). While Social Security has its own annual COLA, TSP balances depend on investment performance and withdrawals. Neither component guarantees that a retiree's total income will keep pace with inflation.
‍

The reduced formula applies only to the basic FERS annuity. For a FERS retiree who also receives Social Security, the Social Security portion gets the full 3.6%; the FERS reduction never touches it. According to Federal News Network’s October 14 reporting, compounded reduced COLAs over a long retirement can create a difference of thousands of dollars between FERS and CSRS annuitants.
‍

2027 COLA Comparison: FERS vs. CSRS vs. Social Security
‍

The table below compares the 2027 adjustment across the three main federal retirement income streams, using the SSA’s October 14, 2026 announcement and OPM’s published COLA rules.
‍

The one-percentage-point gap between CSRS and FERS is consistent with the statutory formula whenever inflation exceeds 3%.
‍

Who Receives the 2027 FERS COLA, and Who Doesn’t
‍

Not every FERS retiree will see a 2.6% bump in January 2027. OPM COLA rules divide FERS annuitants into several groups.
‍

Eligible FERS retirees age 62 and older generally receive the 2.6% adjustment to their basic annuity. Retirees whose annuities have been payable for less than a full year receive a prorated adjustment.
‍

According to Chapter 2 of OPM’s CSRS and FERS Handbook, annuitants in their first year on the roll receive a prorated COLA. The rate equals one-twelfth of the full COLA for each month the annuity has been payable. The same proration rule applies under CSRS.
‍

A retiree who began receiving an annuity partway through 2026 will see only a fraction of the 2.6% in January 2027. The full rate applies in subsequent years, once the annuity has been payable for a complete year before the December 1 effective date.
‍

FERS retirees under age 62 generally receive no annuity COLA. According to OPM, FERS COLAs do not begin until age 62, except for retirees covered by certain special provisions, survivors, and most disability annuitants.
‍

Certain FERS retirees may qualify for COLAs before age 62. This group includes retirees covered by special retirement provisions (such as law enforcement officers, firefighters, and air traffic controllers), eligible disability annuitants, and survivor annuitants. Eligibility and timing depend on the applicable retirement provisions.
‍

A FERS firefighter who retires at age 50 under the special provisions, for example, is eligible for annual COLAs from the start of retirement. The same early-eligibility rule applies to law enforcement officers and air traffic controllers who retire before age 62.
‍

Survivor annuitants under FERS receive COLAs without the age-62 restriction that applies to retirees. A FERS survivor annuitant will see the 2.6% adjustment in January 2027 if the annuity has been payable for a full year by the December 1 effective date.
‍

One group of disability annuitants falls outside the COLA entirely. According to OPM, FERS disability annuitants receiving the 60% rate during their first year on the disability roll will not receive a COLA increase. COLAs resume once the disability annuitant transitions to the 40% rate after year one, continuing until age 62.
‍

The FERS Special Retirement Supplement receives no COLA. COLA increases for FERS annuitants apply to the retiree’s basic annuity, not the annuity supplement. The supplement bridges income between retirement and Social Security eligibility, but it does not receive annual inflation adjustments.
‍

Federal Employee Advisor Network, a retirement planning firm specializing in federal employee benefits, regularly works with clients who assume their full retirement income will adjust with inflation each year. Many realize later that the supplement, which can run several hundred dollars a month, never grows.
‍

To confirm individual eligibility and annuity type, federal annuitants can sign in to their OPM Services Online account. The account shows the retirement category, the date the annuity became payable, and the current gross monthly amount.
‍

What the 2027 FERS COLA Means in Dollar Terms
‍

A 2.6% adjustment produces meaningful but modest monthly increases. The figures below are illustrative gross increases before any deductions and assume the retiree qualifies for the full, un-prorated COLA.
‍

According to FedSmith’s October 14 analysis, a FERS retiree with an average monthly annuity of about $2,400 would see an increase of roughly $62 per month, or about $744 for the year. A CSRS retiree with an average monthly annuity of about $6,000 would see about $216 per month, or roughly $2,592 annually.
‍

OPM rounds the adjusted annuity down to the next whole dollar, so individual results may differ slightly from a straight percentage calculation. For example, a $3,217.50 monthly annuity increased by 2.6% would equal approximately $3,301.16 before rounding. The final amount would be $3,301, assuming the full COLA applies.
‍

For Social Security, the parallel estimate was simpler. According to CNBC’s reporting on the October 14 announcement, Social Security retirement benefits will rise by $75 per month on average as a result of the 3.6% COLA.
‍

A FERS retiree who also collects Social Security receives the two increases separately. The FERS portion applies at 2.6%, and the Social Security portion applies at the full 3.6%.
‍

As SSA Commissioner Frank Bisignano stated in the agency’s announcement, “Social Security will implement this cost-of-living adjustment for 76 million Americans, giving them greater financial stability.”
‍

To estimate your own 2027 increase, multiply your current basic monthly annuity by 0.026. Then multiply your current monthly Social Security benefit, if any, by 0.036. Add the two figures to see the gross monthly increase before Medicare, FEHB, and tax withholding changes.
‍

Medicare Part B and FEHB: What Could Affect Your Net Increase
‍

The gross 2027 FERS COLA is not what lands in a retiree’s bank account. Medicare Part B and FEHB premium changes can meaningfully affect the net raise, though the effect varies by individual.
‍

Medicare Part B premiums may change in 2027, potentially reducing the net benefit of the COLA for retirees enrolled in Medicare. The 2026 Medicare Trustees Report, published June 9, 2026 by the Boards of Trustees of the Federal Hospital Insurance and Federal Supplementary Medical Insurance Trust Funds, projected the standard monthly Part B premium at about $209.50 for 2027, up from $202.90 in 2026.
‍

These figures are projections, not final rates. The Centers for Medicare & Medicaid Services (CMS) typically publishes the official 2027 Part B premium in November, and that figure may differ. Retirees should use the official CMS announcement at Medicare.gov when calculating expected deductions.
‍

If the projection holds, the standard Part B premium rises by $6.60 per month in 2027. That increase would offset roughly 10% of the $62 average FERS COLA for a retiree with a $2,400 basic annuity.
‍

Higher-income retirees pay more. The Income-Related Monthly Adjustment Amount (IRMAA) adds a surcharge for individual filers with modified adjusted gross income above $106,000, or joint filers above $212,000 based on 2026 thresholds. CMS will publish 2027 IRMAA brackets alongside the standard premium.
‍

Higher FEHB premiums could also offset part of the 2027 COLA for some retirees. The actual effect depends on the retiree’s selected health plan, coverage level, annuity amount, and other deductions.
‍

To understand how the 2027 COLA compares with FEHB premiums, compare your plan's monthly premium increase with the dollar increase in your annuity. The program-wide average premium change alone cannot tell you whether your individual retirement income will increase after health insurance deductions.
‍

FEHB Open Season runs from mid-November to mid-December each year. That window is when a retiree can switch plans before 2027 premiums take effect in January.
‍

When the 2027 COLA Takes Effect and Where to See It
‍

The 2027 FERS COLA takes effect December 1, 2026. Federal annuities are paid at the end of each month for the prior month, so the first higher payment arrives in January 2027.
‍

CSRS and FERS retirees can view their new annuity amount in their OPM online account at Services Online. The adjusted figure usually appears in the account after OPM processes the December 1 effective date, typically in late December or early January.
‍

Social Security recipients can view the increase through my Social Security account or by waiting for the mailed notice SSA typically sends in December. Medicare Part B enrollees will see the official 2027 premium figure in my Social Security Message Center in late November.
‍

Keep year-end pay statements from OPM and SSA together in one place. Those documents are the fastest reference when you need to confirm your gross annuity, your Social Security benefit, and your net deposit for 2027 tax planning and FEHB comparisons.
‍

Planning Your 2027 Retirement Income
‍

The 2027 FERS COLA confirms a familiar pattern. When inflation runs above 3%, the FERS diet COLA formula produces a measurably smaller raise than CSRS and Social Security beneficiaries receive.
‍

Combined with potential Medicare Part B and FEHB premium changes, some FERS retirees may see a smaller net increase in January 2027 after all deductions apply. The headline percentage and the deposit in your account can look quite different once Medicare and health premiums come out.
‍

A practical review covers three areas. First, your TSP withdrawal strategy, including whether your current withdrawal rate still matches your spending needs. Second, your FEHB plan choice during Open Season, with attention to your specific plan premium rather than the program-wide average. Third, your overall income allocation across your basic annuity, Social Security, TSP, and any supplement.
‍

Federal Employee Advisor Network, a retirement planning firm specializing in federal employee benefits, recommends completing that review before the first 2027 payment arrives. Working from your actual net figure, rather than the 2.6% headline, keeps your plan aligned with real cash flow.

Frequently Asked Questions
‍

What is the 2027 FERS COLA?
‍

The 2027 FERS COLA is a 2.6% cost-of-living adjustment applied to the basic annuity of eligible Federal Employees Retirement System retirees age 62 and older. SSA announced a 3.6% COLA on October 14, 2026, and the FERS figure follows from the statutory formula. The 2.6% adjustment will first appear in annuity payments issued in January 2027.
‍

Why do FERS retirees get a smaller COLA than CSRS retirees?
‍

FERS retirees receive a reduced COLA because Congress designed FERS as a three-part retirement system that combines a smaller federal pension with Social Security and the Thrift Savings Plan (TSP). Under 5 U.S.C. § 8462, when the qualifying inflation increase exceeds 3%, the FERS adjustment equals the Social Security COLA minus one percentage point.
‍

When will I see the 2027 FERS COLA in my payment?
‍

The 2027 FERS COLA takes effect December 1, 2026. Your first higher payment arrives in January 2027 because federal annuities are paid at the end of each month for the prior month. Your adjusted monthly amount will appear in your OPM Services Online account once processed.
‍

Does the FERS supplement receive the 2027 COLA?
‍

No. According to OPM, the FERS Special Retirement Supplement never receives a COLA. The supplement is a fixed dollar amount designed to bridge income between retirement and Social Security eligibility at age 62. Only the basic FERS annuity receives the 2.6% adjustment in 2027.
‍

Do FERS retirees under 62 receive the 2027 COLA?
‍

Most FERS retirees under age 62 receive no annuity COLA in 2027. Exceptions apply to retirees covered by special retirement provisions, eligible disability annuitants, and survivor annuitants. Eligibility and timing depend on the applicable retirement provisions and the retiree’s annuity category.
‍

How is my 2027 FERS COLA calculated?
‍

Your 2027 FERS COLA equals your current basic monthly annuity multiplied by 2.6%, provided your annuity has been payable for at least a full year. For example, a $2,400 monthly annuity rises by about $62. Annuities payable less than a year receive a prorated adjustment under OPM rules.
