Ten days from now, roughly 75 million Americans find out how big their raise will be. Every major forecaster now puts the Social Security COLA 2027 somewhere between 3.4% and 3.6%. If it lands at 3.4% or higher, it would be the largest cost-of-living adjustment since the 8.7% bump of 2023.
That’s a meaningful jump from the 2.8% beneficiaries got this year. But the final number hinges on one last inflation report, and Medicare premiums could quietly eat into the gain. Here’s what the forecasts say, how the math works and what it could mean for your monthly check.

Social Security COLA 2027: When It Will Be Announced
Mark your calendar for Wednesday, Oct. 14, 2026. That’s when the Bureau of Labor Statistics is scheduled to release September’s Consumer Price Index, the final piece of the puzzle. AARP and Fox Business both report that the official 2027 COLA is expected the same day.
For context, last year’s announcement came a bit later than usual. The Social Security Administration (SSA) revealed the 2026 COLA on Oct. 24, 2025.
The raise itself won’t show up right away. According to the SSA’s pattern since 1983, COLAs take effect with benefits payable for December, which beneficiaries receive in January. So the new amount should hit most checks in January 2027.
What about SSI?
Supplemental Security Income (SSI) recipients usually see the increase a little sooner. For 2026, the SSA said higher SSI payments began on Dec. 31, 2025. Because Jan. 1, 2027, falls on a Friday holiday, the first 2027 SSI payment would typically arrive on Thursday, Dec. 31, 2026. Check the SSA’s official payment calendar to confirm your date.
The Latest Social Security COLA 2027 Estimates
After August inflation data landed on Sept. 11, the big forecasters updated their Social Security COLA 2027 numbers. Here’s where they stand:
| Forecaster | 2027 COLA estimate | Notes |
|---|---|---|
| AARP Public Policy Institute | 3.6% | Uses Cleveland Fed projections for September |
| The Senior Citizens League (TSCL) | 3.5% | Down from 3.6% a month earlier |
| Committee for a Responsible Federal Budget (CRFB) | 3.4% | Nonpartisan budget watchdog |
Independent analyst Mary Johnson, a longtime COLA forecaster, put her estimate at 3.4% in mid-August, according to The Motley Fool. That was before the August CPI report came out.
AARP’s Rich Johnson, vice president for financial security at the AARP Public Policy Institute, sounded fairly confident. “Unless prices change dramatically in September, we’re confident that the COLA will be in the mid-3 percent range,” he told AARP.
Forecasts have moved a lot this year. Mary Johnson projected as high as 4.7% back in June, and TSCL held at 3.8% into July before cooling energy prices pulled estimates down.
How the COLA Is Actually Calculated
The formula is set by law, and it’s simpler than it sounds.
- Take the CPI-W. That’s the Consumer Price Index for Urban Wage Earners and Clerical Workers, a subset of the headline inflation gauge.
- Average July, August and September. That gives you the third-quarter (Q3) average for 2026.
- Compare it to Q3 2025. The percentage increase, rounded to the nearest tenth, becomes the COLA.
- No increase, no COLA. That happened in 2010, 2011 and 2016, when the COLA was 0%.
So far, two of the three months are in. The CPI-W was up 3.4% year over year in July, per CRFB, and 3.5% in August, according to AARP and Fox Business. The broader CPI-U, the number you usually see in headlines, rose 3.4% in August.
That’s why every Social Security COLA 2027 forecast is clustered in the mid-3% range. September would need a big surprise in either direction to push the final number outside it.
TSCL executive director Shannon Benton put it plainly in comments to Fox Business: “The biggest thing we’re watching with the COLA announcement coming are short-term shocks to the economy that push inflation way up or down in the next 30 days.”
What a 3.5% Raise Means for Your Monthly Check
Let’s make it real. According to the SSA’s 2026 COLA fact sheet, the estimated average retired worker benefit in January 2026 was $2,071 a month after the 2.8% COLA.
Here’s how that average check could change under each forecast (our math, based on SSA’s $2,071 figure):
| COLA | Monthly increase | New average benefit | Extra per year |
|---|---|---|---|
| 3.4% (CRFB) | about $70 | about $2,141 | about $845 |
| 3.5% (TSCL) | about $72 | about $2,143 | about $870 |
| 3.6% (AARP) | about $75 | about $2,146 | about $895 |
Your own figure will differ. AARP, for example, used a July 2026 average retiree benefit of about $2,086, which translates to roughly $75 more per month at 3.6%. TSCL uses a different overall average of $1,940.08 and estimates a $67.90 bump at 3.5%.
Other groups get the same percentage. AARP estimates that at 3.6%, the average surviving spouse benefit ($1,933) would rise about $70, and the average disability benefit ($1,635) about $59.
SSI recipients
The 2026 federal SSI payment standard is $994 a month for an individual and $1,491 for a couple, per the SSA. A 3.5% COLA would lift the individual amount to roughly $1,028 (SSA rounds these figures down to the dollar).
The Medicare Part B Catch
Here’s the part retirees often miss. For most people on Medicare, the Part B premium comes straight out of their Social Security check. When Part B goes up, part of your COLA disappears before you ever see it.
The standard Part B premium is $202.90 a month in 2026, up $17.90 from $185 in 2025, according to CMS. That increase swallowed about a third of the average 2026 raise.
The 2027 Part B premium has not been announced yet. CMS typically releases it in the fall, usually in November. But the 2026 Medicare Trustees Report projected a $209.50 monthly premium for 2027, according to the Military Officers Association of America. That would be a $6.60 increase, the smallest percentage rise since 2023.
If both projections hold, here’s how the Social Security COLA 2027 math looks for an average retiree:
- 3.5% COLA on $2,071: about +$72
- Projected Part B increase: about -$6.60
- Net gain: roughly $66 a month
That’s a better net result than this year. Still, it’s only a projection, and higher earners who pay income-related surcharges (IRMAA) could see a bigger bite.
Why a Bigger COLA Isn’t Exactly a Win
A larger COLA sounds like good news. But it exists because prices rose faster. It’s designed to help you keep pace, not get ahead.
Benton has also argued that the CPI-W, which tracks the spending of urban wage earners, doesn’t represent the average senior’s budget. Indivar Dutta-Gupta of the National Academy of Social Insurance told AARP that older Americans are feeling inflation most in groceries, energy, housing and health care.
The pressure is real. AARP cited a Nationwide Retirement Institute survey in which 74% of current beneficiaries said they had made financial changes because rising costs outpaced their benefits. More than half said they had cut discretionary spending.
Inflation isn’t the only headwind for household budgets either. Consumer mood has soured, as we covered in our look at consumer confidence hitting a 12-year low, and the Fed’s preferred gauge is still well above its target, per our August PCE inflation breakdown.
Other Changes Coming on Oct. 14
The COLA isn’t the only number the SSA will update. Expect new figures for:
- The earnings test limit. In 2026, beneficiaries under full retirement age lose $1 for every $2 earned above $24,480. That threshold typically rises each year.
- The taxable wage cap. Social Security payroll tax applies to earnings up to $184,500 in 2026. It’s widely expected to climb in 2027.
- The maximum benefit. A worker retiring at full retirement age can get up to $4,152 a month in 2026.
- Work credits. In 2026, $1,890 in earnings buys one credit. You need 40 credits to qualify for retirement benefits.
If you’re still working, the jobs market matters too. Our September jobs report recap breaks down what the latest hiring slowdown means for older workers and savers.
What to Do Before the Social Security COLA 2027 Arrives
You can’t change the number, but you can get ready for it. Here’s a simple game plan:
- Budget with 3.4%, not 3.6%. Planning around the low end of the forecasts means any surprise is a pleasant one.
- Factor in Medicare. Subtract a few dollars for a likely Part B increase until CMS confirms the 2027 premium.
- Use Medicare open enrollment. It runs Oct. 15 through Dec. 7. A cheaper drug or Medicare Advantage plan could save you more than the COLA adds.
- Sign in to my Social Security. The SSA posts COLA notices in the Message Center of your online account, typically in late November or December.
- Watch for scams. The SSA says it never asks for gift cards, wire transfers or upfront fees. Ignore any call or text claiming you must “verify” your account to get your raise.
The bottom line: the Social Security COLA 2027 is shaping up to be the biggest raise in four years, likely adding around $70 a month to the average retirement check. Check back with USA One News on Oct. 14 for the official number and what it means for your budget.
