Social Security COLA 2027: Oct. 14 Announcement — Forecasts Point to 3.5–3.6%, About $73–$75 More a Month

The official 2027 Social Security cost-of-living adjustment (COLA) has not been published yet as of Oct. 12, 2026. The Bureau of Labor Statistics (BLS) releases September CPI data on Wednesday, Oct. 14, 2026, at 8:30 a.m. ET, and the Social Security Administration (SSA) is widely expected to announce the 2027 COLA the same day. Independent forecasts currently cluster around 3.5% (TSCL / FEDweek) to 3.6% (AARP / Kiplinger). On the average retired-worker benefit near $2,087–$2,088 a month, that would mean roughly $73 to $75 more per month before Medicare Part B and other withholdings — not an official SSA figure until Oct. 14.

Educational only — not Social Security, Medicare, tax, or financial advice. Percentages and dollar examples below are based on published history, independent forecasts, and simple arithmetic. Wait for the official SSA announcement and your own COLA notice before you change a budget. Confirm numbers at SSA.gov and Medicare.gov.

The announcement clock: Oct. 14 at 8:30 a.m. ET

Two things are fixed; everything else is still open.

• Fixed: BLS’s October release calendar lists the Consumer Price Index for September 2026 on Wednesday, Oct. 14, 2026, at 8:30 a.m. Eastern. That September CPI-W reading is the last monthly piece SSA needs for the third-quarter average.
• Expected: SSA typically announces the COLA the same day the final third-quarter CPI-W data are available. Multiple retirement outlets and advocacy groups are pointing to Oct. 14 for the 2027 announcement.
• Still unpublished: As of Oct. 12, SSA’s COLA pages still show only the 2.8% increase that took effect for 2026. There is no official 2027 percentage on SSA.gov yet.

Treat every pre-announcement headline as a forecast. The legal COLA is the one SSA publishes after the CPI-W math is complete.

How the Social Security COLA is calculated

By statute, the COLA is based on the percentage increase in the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W), published by BLS. SSA compares:

• the average CPI-W for the third quarter (July–August–September) of the current year, with
• the average CPI-W for the third quarter of the prior year in which a COLA became effective.

If that percentage increase, rounded to the nearest tenth of one percent, is positive, that is the COLA. If there is no increase (or the rounded result is zero), there is no COLA for that year.

That is why September’s print matters so much: July and August CPI-W are already out; September closes the third-quarter average. July showed roughly a 3.4% year-over-year CPI-W reading and August about 3.5%, according to reporting that cites BLS and TSCL — but those single-month year-over-year figures are not the COLA. Only the Q3-to-Q3 average comparison sets the official rate.

Think of the formula in three steps. First, BLS publishes monthly CPI-W index levels. Second, SSA averages July, August, and September for this year and for the base year. Third, SSA divides the difference by the base-year average, multiplies by 100, and rounds to the nearest tenth of a percent. That rounded positive result becomes the COLA applied to benefits. There is no discretionary “bonus” vote in Congress for the automatic COLA under current law — and there is also no guarantee every year will produce an increase if prices fall on that measure.

Advocacy groups sometimes argue that CPI-W understates inflation for older households (housing, medical care, and other weights differ from a retiree basket). That debate is real in policy circles, but it does not change how SSA must compute the statutory COLA today. For household budgeting, use the official percentage SSA publishes, then adjust your own spending categories with your actual rent, drugs, and utilities — not with a national average alone.

Recent official COLAs (SSA history, by the January payment year):

• 2023: 8.7%
• 2024: 3.2%
• 2025: 2.5%
• 2026: 2.8%

A confirmed mid-3% raise for 2027 would be larger than 2025 and 2026, and smaller than the pandemic-era spike of 2023 — still useful for budgeting, not a windfall that erases every grocery and rent increase of the last few years.

2027 COLA forecast table (independent estimates, not official)

Different organizations use slightly different methods and timing. As of early October 2026, the cluster looks like this:

Source	2027 COLA forecast	Implied avg. monthly raise*	Status
The Senior Citizens League (TSCL)	~3.5%	~$73 on ~$2,087.52 → ~$2,160.58	Independent forecast
FEDweek	~3.5%	Similar to TSCL band	Independent forecast
AARP	~3.6%	~$75 on ~$2,086 average	Independent forecast
Kiplinger (staff economist)	~3.6%	In the AARP-style band	Independent forecast
Social Security Administration	Not published yet	—	Official number due after Oct. 14 CPI

*Dollar examples use published average-benefit snapshots cited by those forecasters. Your own raise = your current benefit × the official COLA (SSA rounds benefits under its rules). Medicare premiums and other deductions can shrink the net deposit.

TSCL’s path through 2026 illustrates how forecasts move: early-year readings near 2.8%, a spring jump toward the high 3s, then a pullback to about 3.6% in July and 3.5% in August. AARP’s September analysis still pointed to 3.6% using CPI-W data through August plus a September inflation projection. One soft or hot September print can still nudge the final tenth of a percent.

Why do TSCL and AARP sometimes differ by a tenth of a percent? Timing and assumptions. One shop may weight the latest month more heavily or plug in a different September inflation path from a Fed district bank model. By early October, with only one CPI print left, that gap usually narrows to something like the current 3.5% vs. 3.6% band. A hotter-than-expected September energy or food print can still lift the Q3 average; a cooler print can shave it. That is precisely why this article refuses to call either number “the” COLA.

For context, a jump from the 2.8% COLA that applied for 2026 into the mid-3s would be the strongest automatic raise since the 3.2% adjustment for 2024 — still far below 2023’s 8.7%. Households that felt squeezed when COLAs cooled in 2025–2026 may breathe easier, but grocery, rent, and insurance line items do not move in lockstep with CPI-W. Keep a personal inflation tracker for the categories you actually buy.

What a 3.5% or 3.6% raise looks like by benefit size

Use this only as a planning worksheet. Multiply your current gross monthly Social Security benefit by 0.035 or 0.036 after SSA announces, then wait for your COLA notice for the exact payable amount.

Current monthly benefit (gross)	At 3.5%	New approx. total	At 3.6%	New approx. total
$1,200	+$42	$1,242	+$43	$1,243
$1,600	+$56	$1,656	+$58	$1,658
$2,087.52 (avg. retired worker snapshot)	+~$73	~$2,160.58	+~$75	~$2,163
$2,800	+$98	$2,898	+$101	$2,901
$3,500	+$123	$3,623	+$126	$3,626

Annualized, the average-worker raise in the 3.5–3.6% band is roughly $876 to $900 before taxes and Medicare. That is meaningful for many households — and still easy to overestimate if Part B, IRMAA, or Medicare Advantage plan costs rise at the same time.

Medicare Part B offset: why the “raise” is not always the deposit

Most people who get Social Security and are enrolled in Medicare Part B have the standard Part B premium withheld from their monthly benefit. That is why retirees often talk about the net COLA after Medicare.

• 2026 standard Part B premium (published): $202.90 per month (CMS).
• 2027 Part B premium: not final in this package. Some Medicare Trustees / industry projections have floated figures near $209.50 — label that clearly as an estimate only, not the CMS final rate. CMS typically finalizes next year’s Part B premium later in the fall.

If a projected Part B increase of about $6–$7 a month were to land near that estimate, a large share of a ~$73–$75 gross COLA could be absorbed for someone paying the standard premium from their check. Higher-income beneficiaries subject to IRMAA pay more than the standard premium, so their offset can be larger. People whose Part B is paid by a state Medicare Savings Program may see a different net picture.

Also remember: Medicare Annual Enrollment Period (AEP) runs Oct. 15 through Dec. 7 for coverage changes effective in 2027. That window opens the day after the expected COLA announcement. Review Part D and Medicare Advantage options at Medicare.gov; do not assume last year’s plan is still the best fit for 2027 premiums and formularies.

Two practical Medicare notes for the same two-week stretch:

• Do not wait for the COLA headline alone to pick a 2027 plan. Premiums, deductibles, networks, and Part D formularies can change even when the COLA looks “about right.” Compare on Medicare.gov during AEP.
• Extra Help and Medicare Savings Programs can reduce Part D costs and, in some cases, help with Part B premiums for people with limited income and resources. Start at SSA.gov (Extra Help) and Medicare.gov (Medicare Savings Programs) or your state Medicaid office — not a Facebook lead form.

If your Social Security deposit already shows a Medicare deduction line, open last year’s COLA notice or your my Social Security benefit verification letter so you can compare gross benefit vs. net deposit side by side when the 2027 numbers post.

When the raise shows up: OASI vs. SSI timing

For Social Security retirement, survivor, and disability benefits (OASI / SSDI paid on the regular schedules), a COLA generally shows up in the January payments — that is, benefits for December paid in January under SSA’s rules, on the birthday-based Wednesday schedule for most beneficiaries.

For Supplemental Security Income (SSI), the federal payment for January is normally due on the 1st. When January 1 is a federal holiday (as it is in 2027), SSI payments for January are typically made at the end of the prior December — often cited as around Dec. 31, 2026 for the January 2027 SSI amount that already includes the new COLA. People who receive both Social Security and SSI should watch both schedules; SSA notes that some beneficiaries get both.

Exact deposit dates for your birthday group come from SSA’s published payment calendars and your my Social Security account — not from a news headline. Set up or sign in to my Social Security so you can get Message Center notices when COLA information is posted.

Birthday-group reminder for retirement and survivor benefits paid on the Wednesday schedule (most people who started benefits in May 1997 or later): SSA pays on the second, third, or fourth Wednesday depending on whether your birth date falls on the 1st–10th, 11th–20th, or 21st–31st. The COLA changes the amount; it does not rewrite that Wednesday logic. When a scheduled payment date falls on a weekend or holiday, SSA’s published calendar already shifts the deposit — which is why you should rely on the official 2027 payment schedule once SSA posts it, not on a rule of thumb from a neighbor.

People paid on the “3rd of the month” (generally those who began receiving benefits before May 1997, and many who get both Social Security and SSI) follow a different day. Either way, January is when the new COLA shows up in regular Social Security deposits; SSI’s January amount often arrives a day or two earlier at year-end when the 1st is a holiday.

Checklist before Oct. 14 (and right after)

• Do not lock a budget on a forecast. Pencil 3.5–3.6% as a planning band; rewrite the line item when SSA publishes the official rate.
• Know your current gross benefit. Your raise is a percentage of what SSA pays you now, not of a national average.
• Separate gross COLA from net deposit. Ask what Part B (and any IRMAA) will be for 2027 once CMS publishes it.
• Create or unlock my Social Security at SSA.gov so COLA notices can appear in Message Center (historically available online in late November for many beneficiaries).
• Mark AEP: Oct. 15–Dec. 7 for 2027 Medicare plan changes. Use Medicare.gov plan finder tools; bring a current medication list.
• Watch for scam spikes (see next section) the week of the announcement and when COLA notices mail or post online.
• If you still get a paper check, Treasury pushes electronic payment — go to godirect.gov; SSA services are free.
• Working while on benefits? Earnings limits for people under full retirement age are separate from COLA; report work as SSA requires.

Scam warning: COLA season is peak fraud season

SSA repeats this every year for a reason: when COLA headlines hit, phone, text, email, and social-media scams spike. Hard rules:

• SSA will not call, text, or email you to demand immediate payment by gift card, wire, cryptocurrency, or cash reload.
• SSA will not threaten to suspend your benefits today unless you “verify” by sharing a one-time code, bank password, or full Social Security number with a stranger who contacted you first.
• Official COLA information appears on SSA.gov and in your own my Social Security Message Center / mailed notice — not on a random Facebook ad or a link in an unsolicited text.
• Report suspected Social Security fraud to the Inspector General at oig.ssa.gov/report or 1-800-269-0271 (TTY 1-866-501-2101).

If someone pressures you to “secure your COLA raise” for a fee, hang up. The COLA is automatic for people already receiving benefits; you do not pay a private company to “apply” for it.

Common COLA-season scripts include: “Your COLA was denied — press 1”; “We need to deposit your back pay — confirm your routing number”; and fake websites that mimic SSA.gov with an extra hyphen or misspelling. Bookmark https://www.ssa.gov yourself. Do not tap links in texts. If you already shared information, call your bank, consider a credit freeze, and report to the SSA OIG and to reportfraud.ftc.gov.

FAQ

Is the 2027 COLA official yet?
No. As of Oct. 12, 2026, SSA has not published a 2027 COLA. Forecasts of 3.5–3.6% are independent estimates.

When will we know the official number?
After BLS releases September CPI on Oct. 14, 2026, at 8:30 a.m. ET. SSA is expected to announce the COLA the same day once the Q3 CPI-W average is known.

What were recent COLAs?
8.7% (2023), 3.2% (2024), 2.5% (2025), 2.8% (2026) — SSA official history.

How much will the average retiree get?
On a ~$2,087.52 average retired-worker benefit (TSCL/SSA August 2026 snapshot cited in forecast coverage), 3.5% is about +$73/month; 3.6% is about +$75/month. Your amount depends on your own benefit.

Will Medicare take part of the raise?
Often yes, if Part B is withheld from your check and the 2027 premium rises. The 2026 standard Part B premium is $202.90. Any ~$209.50 figure for 2027 is a projection until CMS finalizes it — label it as an estimate.

When does the raise hit my bank?
Social Security payments reflecting the new COLA generally appear in January 2027 deposits (by birthday schedule). SSI for January often pays at the end of December when Jan. 1 is a holiday.

Where should I check?
SSA.gov for COLA and my Social Security; Medicare.gov for Part B / plan enrollment; CMS.gov for official premium fact sheets. Ignore paid “COLA claim” ads.

Bottom line for U.S. retirees

Oct. 14 is the date that turns forecasts into an official percentage. Plan with a 3.5–3.6% band and about $73–$75 on the average retired-worker check, then replace those figures with SSA’s announcement and your own notice. Keep Medicare Part B and AEP (Oct. 15–Dec. 7) in the same conversation so you budget the net deposit, not just the headline raise — and treat unsolicited COLA calls as fraud until proven otherwise on SSA.gov.
