2027 Social Security COLA: For the first time in three years, retirees are looking at a Social Security raise that could actually outpace the rising cost of Medicare. New Consumer Price Index data released this week points to a 2027 Social Security COLA as high as 3.6%, according to the latest estimate from the Senior Citizens League, while the Medicare Trustees Report projects the standard Part B premium will climb only about 3.25% next year, to roughly $209.50 a month. If both figures hold, 2027 would mark the first year since 2023 that the cost-of-living adjustment has grown faster than the Part B premium eating into it.
That gap matters more than it might sound. Every year, millions of beneficiaries watch their raise get partially cancelled out because Medicare’s Part B premium is deducted straight from their monthly Social Security check before it ever reaches their bank account. In 2026, that dynamic hit particularly hard: the Part B premium jumped 9.7%, nearly three and a half times faster than the 2.8% COLA it was supposed to be offset by. Independent analyst Mary Johnson and several advocacy groups are now projecting a rare reversal for 2027, though every figure in play remains an estimate until the Social Security Administration makes its official announcement on October 14, 2026. This guide breaks down where the numbers currently stand, why the estimates keep shifting, and what beneficiaries should actually expect. We’ll be updating this article monthly as new inflation data refines the forecast.
Latest 2027 Social Security COLA Estimates
Multiple organizations independently track and forecast the annual COLA before the Social Security Administration makes it official, and their estimates have been narrowing as more inflation data comes in through the summer.
| Source | 2027 COLA Estimate |
|---|---|
| Senior Citizens League | 3.6% |
| Independent analyst Mary Johnson | 3.4% |
| AARP | 3.5% |
| Committee for a Responsible Federal Budget | 3.2% |
These estimates have actually been trending downward over recent months. Mary Johnson’s own forecast moved from 4.7% in June, to 3.7% the following month, to 3.4% now, illustrating just how sensitive these projections are to each new round of Consumer Price Index data. July’s inflation report showed consumer prices up 3.4% year over year, down slightly from 3.5% in June, which is largely what pulled several forecasts lower. Core CPI, which strips out volatile food and energy prices, rose 2.5% annually, matching Wall Street’s expectations.

Why the COLA Number Keeps Moving Every Month
The annual Social Security cost-of-living adjustment is calculated using the Consumer Price Index for Urban Wage Earners and Clerical Workers, known as CPI-W, averaged specifically across the third quarter, meaning July, August, and September. Because the official calculation only uses those three months, every inflation report released before October carries real weight in shaping the final number, and estimates published in June or July are inherently less reliable than ones published in September.
This is also why analysts have been revising their forecasts downward as the summer progressed. Elevated readings earlier in the year pushed some early estimates as high as 4.7%, but a cooling trend through July has brought most projections back into a tighter 3.2% to 3.6% range. The Social Security Administration will not confirm the actual figure until October 14, 2026, once the full third-quarter data set is available, and the confirmed adjustment then takes effect with January 2027 payments.
What’s Driving Inflation and the Higher COLA This Year
Behind the numbers, several economists have pointed to tariff policy as a meaningful contributor to the elevated inflation readings feeding into this year’s COLA calculation. Certain price categories have stayed persistently high even as headline inflation cools, with outpatient hospital care rising 5.8% according to Mary Johnson’s analysis, a detail that matters specifically for retirees since healthcare costs make up a disproportionate share of typical senior spending compared to the general CPI-W basket the COLA is actually calculated from.
This dynamic has been described by some analysts as a second consecutive year of a larger-than-typical adjustment tied to trade policy effects on consumer prices, following a similar pattern that shaped the 2026 COLA. Whether that continues into 2028 depends heavily on how tariff policy and broader inflation trends develop over the coming year, something no current forecast can reliably predict this far out.
Why Medicare Part B Premiums Usually Eat Into the COLA
For beneficiaries enrolled in Medicare Part B who have their premium deducted directly from their Social Security payment, the annual COLA and the annual Part B premium increase are functionally in competition with each other. A large COLA paired with an even larger premium hike can leave a beneficiary with less net monthly income than the headline percentage suggests.
The 2026 example illustrates just how sharply that gap can bite. The standard Part B premium rose from $185 to $202.90, a 9.7% jump, while the COLA that same year landed at only 2.8%. According to policy analysis from the Center for Retirement Research, that increase alone consumed more than a quarter of the entire 2026 cost-of-living adjustment, and pushed Part B premiums to an all-time high as a share of the average retired worker’s benefit, at 9.4%.
2027 Projections: COLA vs Part B Premium Side by Side
| Category | 2026 Confirmed | 2027 Projected |
|---|---|---|
| Social Security COLA | 2.8% | 3.2% to 3.6% |
| Standard Part B monthly premium | $202.90 | Approximately $209.50 (Trustees Report); some private forecasters project up to $216 to $219 |
| Part B premium percentage increase | 9.7% | Approximately 3.25% |
| Average retired worker monthly benefit | $2,071 | Roughly $67 to $75 higher, based on current COLA estimates |
If the final numbers land close to current projections, 2027 would be the first year since 2023 that the COLA percentage exceeds the Part B premium percentage increase, a reversal significant enough that some retirement analysts are already calling it a modest silver lining after several difficult years for fixed-income retirees.
Not Every Beneficiary Sees the Same Net Increase
An important, often overlooked detail is that federal retirees under the Federal Employees Retirement System, or FERS, do not receive the full COLA percentage that Social Security recipients and Civil Service Retirement System retirees get. Under what is sometimes called the diet-COLA rule, FERS retirees generally receive a reduced adjustment when the full COLA exceeds 2%, meaning a 3.6% Social Security COLA could translate to roughly a 2.6% increase for many FERS annuitants, a full percentage point below what CSRS retirees and standard Social Security beneficiaries would receive.
Beneficiaries who pay an Income-Related Monthly Adjustment Amount, or IRMAA, because of higher income also need to factor in that their 2027 surcharge will be calculated using 2025 income data, which can catch retirees off guard if they had an unusually high-income year, such as one involving a large final-year payout or a Roth conversion, two years before the surcharge actually applies.

What Beneficiaries Should Do While Waiting for the Official Numbers
- Treat every current figure as a planning estimate, not a confirmed amount, since both the COLA and the Part B premium remain projections until October and November respectively.
- Check whether you are subject to IRMAA based on your 2025 income, since that determines whether you pay above the standard Part B premium in 2027.
- If you are a FERS retiree, budget using the reduced diet-COLA estimate rather than the full Social Security percentage, since your actual increase will likely be lower.
- Watch for the Social Security Administration’s official COLA announcement on October 14, 2026, followed by your personalized benefit statement showing your exact new payment amount.
- Review your Medicare Part D and Medicare Advantage options during the Annual Enrollment Period, since drug and plan costs also shift annually alongside Part B.
- Set up or check your mySocialSecurity account online to view your current benefit statement and any updates as they are posted.

FAQs
What is the 2027 Social Security COLA estimate right now?
Current estimates range from 3.2% to 3.6% depending on the source, with the Senior Citizens League projecting the high end at 3.6% and the Committee for a Responsible Federal Budget projecting the low end at 3.2%. The official figure will not be confirmed until October 14, 2026.
When will the official 2027 COLA be announced?
The Social Security Administration typically announces the final cost-of-living adjustment in mid-October each year, based on third-quarter CPI-W data. The 2027 announcement is expected on October 14, 2026, with the new amount taking effect in January 2027.
Will the 2027 COLA actually be bigger than the Medicare Part B premium increase?
Based on current projections, yes. The COLA is estimated at 3.2% to 3.6%, while the Part B premium is projected to rise around 3.25%, which would make 2027 the first year since 2023 that the COLA outpaces the premium increase percentage-wise.
How much will Medicare Part B cost in 2027?
The 2026 Medicare Trustees Report projects a standard Part B premium of about $209.50 a month, up from $202.90 in 2026, though some private forecasters expect the final figure to land somewhat higher, in the $216 to $219 range. The Centers for Medicare and Medicaid Services will confirm the official amount in November 2026.
Why do Social Security COLA estimates keep changing?
The COLA is calculated using average CPI-W data across July, August, and September only, so each new inflation report released before October shifts the estimate. Forecasts made earlier in the year, before all three months of data exist, are inherently less reliable than those made closer to the official announcement.
Do federal retirees get the same COLA as Social Security recipients?
Not necessarily. Civil Service Retirement System retirees and Social Security beneficiaries generally receive the full COLA, but Federal Employees Retirement System retirees receive a reduced adjustment under the diet-COLA rule whenever the full COLA exceeds 2%, meaning a 3.6% Social Security COLA could translate to roughly 2.6% for many FERS annuitants.
How much extra money will the average retiree get in 2027?
Based on current COLA estimates and an average retired worker benefit of around $2,071, beneficiaries could see an increase of roughly $67 to $75 a month, though the exact figure depends on the final COLA percentage confirmed in October.
Conclusion
The projected 2027 Social Security COLA of 3.2% to 3.6% represents a meaningful shift from the pattern retirees have faced in recent years, where Medicare premium hikes routinely outpaced and diluted the annual raise meant to protect their purchasing power. With the Part B premium currently projected to rise at a comparatively modest 3.25%, this could be the first year since 2023 where beneficiaries actually keep more of their cost-of-living increase rather than watching most of it disappear into higher healthcare costs. Both figures remain estimates for now, with the Social Security Administration confirming the final COLA on October 14, 2026 and Medicare finalizing 2027 premiums the following month, so beneficiaries should treat current numbers as a planning guide rather than a locked-in amount until those official announcements arrive.
