2027 COLA Count Drops to 3.1%: What Federal Retirees Should Review Now

‍

The 2027 COLA count has dropped to 3.1% through June, down from 3.6% through May, according to FedWeek's tracking of the inflation index used to set the annual adjustment. This is a running count, not the final number. The cost-of-living adjustment (COLA) is the yearly increase applied to federal annuities and Social Security benefits to help retirement income keep pace with inflation.

‍

The count still sits above the 3% mark, so it matters especially for retirees under the Federal Employees Retirement System (FERS). It also affects broader income planning for those under the Civil Service Retirement System (CSRS) and Social Security recipients.

‍

This article explains what changed, why the number isn't confirmed, how the 3% threshold affects FERS retirees, and the specific items you should review now. The official COLA will be announced in October 2026 and applied to federal annuities under U.S. Office of Personnel Management (OPM) rules. For the running month-by-month figure, see the latest 2027 FERS and CSRS COLA estimate.

‍

What Changed in the 2027 COLA Count?

‍

The 2027 COLA count fell from 3.6% through May to 3.1% through June 2026. According to FedWeek, the running count declined by about half a percentage point after the June reading of the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) came in lower than May's figure. The CPI-W is the specific inflation index the Social Security Administration uses to calculate each COLA.

‍

Why did it drop? Easing energy prices drove most of the decline, following a suspension of hostilities with Iran that had earlier pushed gasoline costs higher.

‍

That trend isn't locked in. FedWeek notes that renewed tensions have again started to lift energy costs. The July, August, and September CPI-W readings are the only months that count toward the official calculation, and they could move the final number in either direction. The June CPI-W measured 327.075 against the third-quarter 2025 baseline of 317.265, which works out to roughly 3.1%, as reported by MOAA's COLA Watch.

‍

Why the Final 2027 COLA Is Not Confirmed Yet

‍

The 3.1% figure is a running count, not the official 2027 COLA. The Social Security Administration announces the Social Security COLA in mid-October 2026, after the September CPI-W data is released. The same underlying figure then applies to FERS and CSRS annuities under OPM rules. Until then, every published percentage is an estimate based on incomplete data.

‍

Here's why the current count carries an asterisk. The Social Security Administration compares the average CPI-W for July, August, and September of the current year against the same three months of the prior year. No other months enter the formula directly.

‍

The January-through-June readings, including the June figure driving today's 3.1% count, help analysts see where the calculation is heading. But they don't directly set the result. That's why the accurate language is "current count," "running estimate," or "if finalized," not "the 2027 COLA is 3.1%."

‍

Why the 3% Level Matters for FERS Retirees

‍

The 3% threshold is the single most important number for FERS retirees watching the 2027 COLA. FERS annuitants don't always receive the same adjustment as CSRS annuitants, because of a provision often called the "FERS COLA cap" or "diet COLA." According to FedWeek, the rules work in tiers based on where the final CPI-W count lands.

‍

If the final count stays above 3%, eligible FERS retirees generally receive 1 percentage point less than the indicated figure. If the count finishes between 2% and 3%, those FERS retirees receive a flat 2%. Retirees under CSRS receive the full amount.

‍

One qualification matters here. FERS annuitants generally aren't eligible for COLAs until age 62, except for survivor benefits, disability benefits, and certain special provision retirements such as law enforcement officers, firefighters, and air traffic controllers.

‍

The current count sits at 3.1%, just above the threshold. A small further decline could shift the entire FERS outcome from the reduced formula into the flat 2% band.

‍

What a 3.1% COLA Could Mean for FERS and CSRS Retirees

‍

The table below shows how three plausible final outcomes would translate into actual adjustments for each retirement system, based on the COLA rules described by FedWeek. These are illustrative scenarios, not predictions.

‍

‍

The pattern is clear. The gap between the two systems begins once inflation rises above 2%. Above 3%, most eligible FERS retirees generally receive one percentage point less than CSRS retirees.

‍

For context, FedWeek reports that the January 2023 increase reached 8.7% for CSRS and 7.7% for FERS, the largest in four decades. Since then, annual COLAs have run 3.2%, 2.5%, and 2.8% under CSRS, and 2.2%, 2%, and 2% under FERS.

‍

How Social Security Fits Into the COLA Picture

‍

Social Security follows its own COLA rules, separate from your federal pension. Many FERS retirees receive Social Security benefits in addition to their annuity. Those Social Security benefits generally receive the full Social Security COLA, the same full CPI-W figure that applies to CSRS annuities, separate from the reduced FERS annuity COLA calculation.

‍

This is why total-income review matters more than tracking a single percentage. Your FERS annuity, your Social Security benefit, and any withdrawals from your Thrift Savings Plan (TSP) each behave differently. The TSP is the federal government's tax-advantaged retirement savings program.

‍

TSP withdrawals don't automatically rise with inflation at all. They change only if you adjust them. Looking only at your pension COLA gives you an incomplete picture of how your spending power will actually change next year. If you want to model the TSP piece, you can estimate your TSP retirement income directly.

‍

Why a Lower COLA Count Still Requires Planning

‍

A lower COLA count doesn't make planning less important. If anything, the opposite is true. A smaller adjustment means a smaller income increase, which leaves less cushion against the costs that quietly erode your budget.

‍

Several of those costs move independently of your COLA. Premiums under the Federal Employees Health Benefits Program (FEHB), Medicare Part B premiums, federal and state taxes, and general inflation can each offset part or all of an annual adjustment. A 3.1% raise on your annuity means little if healthcare premiums and Part B climb by a comparable amount.

‍

Here's the practical takeaway. Don't assume a COLA, reduced or not, will fully protect your purchasing power on its own.

‍

What Federal Retirees Should Review Now

‍

Rather than react to a running count, use this update as a prompt for a structured income review. Work through these five areas:

‍

1. Monthly retirement income. Add up every stream: your FERS or CSRS pension, Social Security, TSP withdrawals, survivor benefits, and any other income. Knowing the total lets you judge how much a one-point COLA swing actually matters to your budget.
   
   
2. TSP withdrawal strategy. Because TSP withdrawals don't adjust for inflation automatically, some retirees increase them to cover rising costs. Doing so can shorten the long-term life of the account, so weigh any increase against how long you need the balance to last.
   
   
3. Tax planning. Review how your pension income, the taxable portion of Social Security, TSP withdrawals, potential Roth conversions, and required minimum distributions (RMDs) interact. A COLA can nudge you into a higher bracket or increase the share of Social Security that's taxed. For a deeper look, see our guide to taxes on federal retirement income.
   
   
4. FEHB and Medicare costs. Healthcare is the expense most likely to absorb a COLA. Review FEHB and Medicare Part B costs alongside your expected adjustment to see the net effect on your income.
   
   
5. Survivor planning. Consider how household income would change if one spouse passed away. A lost Social Security benefit or a reduced annuity can reshape the budget far more than a fraction of a COLA point.
   
   

What Employees Near Retirement Should Consider

‍

If you're close to retiring, the 2027 COLA count intersects with several timing decisions. Your retirement date determines whether your first COLA is prorated. An annuity that begins partway through 2026 generally earns only a fraction of the first adjustment. Your FERS eligibility matters too, since the COLA generally doesn't apply until age 62 outside the special-provisions categories.

‍

Beyond the COLA itself, weigh when to claim Social Security, when to begin TSP withdrawals, and how FEHB coverage will coordinate with Medicare once you reach 65. These choices interact. Locking in one without considering the others can cost more over a full retirement than any single year's COLA difference. You may benefit from reviewing these decisions together rather than treating COLA, TSP withdrawals, taxes, and healthcare costs separately.

‍

Common Mistakes to Avoid

‍

Even well-informed retirees stumble on a few recurring errors around COLA season:

‍

• Treating 3.1% as the final 2027 COLA when it's only a running count through June.

• Assuming FERS and CSRS retirees receive the same increase, when the FERS cap often reduces the FERS figure above 2%.

• Forgetting that TSP withdrawals don't adjust automatically for inflation.

• Ignoring taxes, FEHB premiums, and Medicare costs that can offset the entire adjustment.

‍

Bottom Line

‍

The 2027 COLA count stands at about 3.1% through June 2026, according to FedWeek, down from 3.6% through May on easing energy prices. That number isn't final. The official 2027 COLA will be confirmed in October 2026 after September CPI-W data is in, then applied to federal annuities under OPM rules.

‍

FERS retirees should watch the 3% threshold especially closely, since a small move below it would shift the FERS result to a flat 2%. Treat this update as a reason to review your total retirement income, not as a reason to make quick financial decisions. Schedule a free consultation with a federal retirement specialist to turn each COLA milestone into a full income, tax, and healthcare review.

Frequently Asked Questions

‍

1. Is the 2027 federal retiree COLA final?

No. The 3.1% figure is a running count through June 2026, not the final 2027 COLA. The Social Security Administration announces the figure in October 2026, based only on the average CPI-W for July, August, and September compared with the same months in 2025. It's then applied to federal annuities under OPM rules.

‍

2. Why does the 3% level matter for FERS retirees?

The 3% level is the threshold where the FERS COLA cap changes the outcome. If the final count stays above 3%, most eligible FERS retirees generally receive 1 percentage point less than the full figure, according to FedWeek. Between 2% and 3%, eligible FERS retirees generally receive a flat 2%.

‍

3. Do CSRS retirees receive the same COLA as FERS retirees?

Not always. CSRS retirees generally receive the full applicable COLA, while FERS retirees may receive a reduced amount when inflation runs above 2%. Any Social Security benefits a FERS retiree receives are a separate benefit that generally gets the full Social Security COLA, apart from the capped FERS annuity adjustment.

‍

4. Should federal retirees change TSP withdrawals now?

Not on the basis of the current COLA count alone. Thrift Savings Plan withdrawals don't adjust automatically for inflation, so review any change alongside your pension income, Social Security, taxes, and healthcare costs. Increasing withdrawals to cover expenses can shorten how long the account lasts.
