2027 COLA Estimate: The Social Security COLA 2027 increase is now projected to land between 3.4% and 3.6%, according to the newest round of forecasts released after the August 2026 Consumer Price Index report. The Senior Citizens League and independent analyst Mary Johnson both currently peg the 2027 cost-of-living adjustment at 3.5%, while AARP’s latest model, updated on September 19 after the August inflation reading, points to 3.6%. The Committee for a Responsible Federal Budget, a nonpartisan budget watchdog, has the number slightly lower at 3.4%. All of these remain projections. The Social Security Administration will not confirm the official 2027 COLA until the September Consumer Price Index report is published, which locks in the last of the three months used in the government’s formula.
If the final number lands anywhere in the 3.4% to 3.6% range, it would be the largest Social Security benefit increase since the 8.7% adjustment in 2023, and noticeably higher than the 2.8% raise beneficiaries received for 2026. For the average retired worker, who received roughly $2,071 a month as of January 2026, a 3.5% raise would add about $72 to $75 to the monthly check, pushing the average payment above $2,145. Nearly 75 million Americans, including retirees, disabled workers, survivors, and Supplemental Security Income recipients, will feel the effect of whatever number the Social Security Administration ultimately announces. We’ll be updating this article monthly as new inflation data and forecaster estimates are released, so the figures below reflect the most current projections available.

What Is the Social Security COLA and How Is It Calculated
The cost-of-living adjustment is an annual increase applied to Social Security and Supplemental Security Income benefits so that monthly checks keep pace with inflation. The adjustment has been calculated automatically every year since 1975, replacing the old system in which Congress had to pass special legislation to raise benefits.
The Social Security COLA formula compares the average Consumer Price Index for Urban Wage Earners and Clerical Workers, known as CPI-W, across the third quarter of the current year (July, August, and September) with the average CPI-W from the third quarter of the previous year in which a COLA took effect. The percentage difference between those two averages, rounded to the nearest tenth of a percent, becomes the official COLA. If prices do not rise, there is no increase for that year.
For the 2027 cycle, the Bureau of Labor Statistics has already released July and August 2026 inflation data. The August CPI-W came in 3.5% higher than the same month a year earlier, while the broader CPI-U rose 3.4% over the same period. The September figure, due out on the same day the Social Security Administration makes its announcement, will complete the three-month average used in the final calculation.

Latest 2027 COLA Estimates: What Each Forecaster Predicts
Multiple organizations track inflation data throughout the year and publish their own 2027 Social Security COLA estimate ahead of the official announcement. Their numbers have moved several times in 2026 as new inflation reports came out.
| Forecaster | Latest Estimate | Based On |
|---|---|---|
| AARP | 3.6% | August 2026 CPI-W plus Cleveland Fed inflation projections for September |
| The Senior Citizens League (TSCL) | 3.5% | August 2026 CPI-W data |
| Mary Johnson (independent analyst) | 3.5% | August 2026 CPI-W and CPI-U readings |
| Committee for a Responsible Federal Budget | 3.4% | Third-quarter inflation trend through August |
Estimates swung considerably earlier in the year. TSCL’s projection moved from an initial 2.8% forecast in January up to as high as 3.9% in the spring before settling near 3.5%. Mary Johnson’s forecast was even more volatile, briefly touching 4.7% in June after a hot inflation reading before cooling back down to the mid-3% range by August. Analysts note that with only the September report left to release, the range of outcomes has narrowed considerably, and most groups now expect the final Social Security cost-of-living adjustment to land somewhere between 3.4% and 3.6%.
How Much Extra Money the 2027 COLA Could Mean for You
A higher COLA increase translates directly into a bigger monthly Social Security check, though the exact dollar amount depends on your current benefit amount. Below is a general breakdown based on the average retired-worker benefit of $2,071 per month, using several possible COLA outcomes.
| Estimated COLA | New Average Monthly Benefit | Monthly Increase | Annual Increase |
|---|---|---|---|
| 3.4% | About $2,141 | About $70 | About $844 |
| 3.5% | About $2,144 | About $72 | About $869 |
| 3.6% | About $2,146 | About $75 | About $895 |
These figures are averages. Your own increase will be a percentage of your current benefit amount, so higher earners with larger checks will see a bigger dollar increase, while smaller checks will see a smaller one in raw dollar terms even though the percentage is identical for everyone.

Social Security COLA History: 2016 to 2027
Looking at past increases helps put the projected 2027 COLA in context. Over the last decade, adjustments have ranged from a 0% freeze to the largest increase in four decades.
| Year | COLA Percentage |
|---|---|
| 2016 | 0.0% |
| 2017 | 0.3% |
| 2018 | 2.0% |
| 2019 | 2.8% |
| 2020 | 1.6% |
| 2021 | 1.3% |
| 2022 | 5.9% |
| 2023 | 8.7% |
| 2024 | 3.2% |
| 2025 | 2.5% |
| 2026 | 2.8% |
| 2027 | Projected 3.4% to 3.6% (official figure due October 14, 2026) |
If the final 2027 number comes in around 3.5%, it would rank among the larger increases of the past two decades, trailing only 2022 and 2023, and would mark the third straight year the adjustment has trended upward after bottoming out at 2.5% in 2025.
When Will the 2027 COLA Be Announced
The Social Security Administration is scheduled to release the official 2027 cost-of-living adjustment on October 14, 2026, at approximately 8:30 a.m. Eastern time, the same morning the Bureau of Labor Statistics publishes the September Consumer Price Index report. This date follows the standard pattern the agency has used in recent years, with the announcement typically coming in mid-October once all three months of third-quarter data are available.
After the announcement, the Social Security Administration mails personalized COLA notices to beneficiaries in early December, spelling out the exact new benefit amount for each individual. Anyone with a My Social Security online account can also view this notice digitally, usually before the mailed version arrives, through the account’s Message Center.

2027 Social Security Payment Dates After the COLA Takes Effect
The increased benefit amount does not appear in every recipient’s check at the same time. Payment timing depends on the type of benefit and, for retirement and disability beneficiaries, the recipient’s date of birth.
| Recipient Group | First Payment With 2027 COLA |
|---|---|
| SSI recipients and those who started benefits before May 1997 | December 31, 2026 |
| Born on the 1st through the 10th of the month | January 13, 2027 |
| Born on the 11th through the 20th of the month | January 20, 2027 |
| Born on the 21st through the 31st of the month | January 27, 2027 |
SSI payments move earlier because January 1, 2027 falls on a holiday and January 3 falls on a Sunday, pushing the payment back to the last business day of December.
How the COLA Affects Medicare Part B Premiums
Most people who receive Social Security have their Medicare Part B premium deducted directly from their monthly benefit. Because the Part B premium for the coming year is typically announced around the same time as the COLA, any increase in that premium is factored into the net benefit boost. The Centers for Medicare and Medicaid Services usually confirms the standard Part B premium in November, and the Social Security Administration incorporates that figure into the personalized COLA notices sent in December. Beneficiaries who are also enrolled in Medicare should watch for both announcements, since a higher Part B premium can offset part of the raw COLA increase.
How to Apply for Social Security Benefits and Check Your Status
Beneficiaries and new applicants can manage nearly every part of the process directly through the Social Security Administration’s official online systems rather than visiting a field office in person.
How to apply: New retirement, disability, or survivor claims can be filed online through the Social Security Administration’s benefits application portal. Applicants generally need identifying information, employment history, and banking details for direct deposit.
Processing time: Standard retirement applications are typically processed within a few weeks, while disability claims often take several months because of the additional medical review involved.
Payment schedule: Ongoing benefit payments follow the birth-date schedule shown in the payment dates table above, and SSI payments are issued on the 1st of each month unless that date falls on a weekend or holiday.

FAQs
What is the projected Social Security COLA for 2027?
Current forecasts from AARP, The Senior Citizens League, and independent analysts place the 2027 COLA between 3.4% and 3.6%, though the official figure will not be confirmed until October 14, 2026.
When will the official 2027 COLA be announced?
The Social Security Administration will announce the official 2027 cost-of-living adjustment on October 14, 2026, alongside the release of the September Consumer Price Index report.
How much will my Social Security check increase in 2027?
The increase depends on your current benefit amount and the final COLA percentage. For the average retired worker receiving about $2,071 a month, a 3.5% COLA would add roughly $72 per month.
Why does the Social Security COLA change every year?
The COLA is tied to inflation as measured by the CPI-W. When prices rise, benefits increase to help recipients maintain their purchasing power; when prices stay flat, there is no increase.
Will Medicare premiums reduce my 2027 COLA increase?
Possibly. Since most Medicare Part B premiums are deducted directly from Social Security payments, an increase in the premium can offset part of the raw COLA increase for beneficiaries enrolled in Medicare.
When will I receive my first payment with the new COLA?
SSI recipients and certain long-time beneficiaries will see the increase starting December 31, 2026, while most Social Security retirement and disability recipients will see it in their January 2027 payment, timed according to their birth date.
Is the 2027 COLA estimate final?
No. Every figure published before October 14, 2026 is a projection based on partial inflation data. The Social Security Administration's number, based on the complete July-through-September CPI-W average, is the only official figure.
How is the Social Security COLA percentage calculated?
It is based on the percentage change in the average CPI-W between the third quarter of the current year and the third quarter of the last year a COLA was applied, rounded to the nearest tenth of a percent.
What was the highest COLA in Social Security history?
The largest increase since automatic COLAs began in 1975 was 14.3% in 1980. In recent history, the 8.7% increase in 2023 was the highest in over four decades.
Does everyone get the same dollar increase from the COLA?
No. The COLA is a percentage increase, so it is applied to each individual's current benefit amount, meaning people with higher benefits see a larger dollar increase than people with smaller benefits.
Can the Social Security COLA ever be negative?
No. If inflation is flat or negative, the COLA is simply 0% for that year rather than a reduction in benefits.
Conclusion
The Social Security COLA 2027 increase is shaping up to be the largest benefit boost beneficiaries have seen since 2023, with most forecasters converging around a 3.4% to 3.6% range ahead of the official October 14, 2026 announcement. While the exact number will not be locked in until the September inflation data is released, retirees, disabled workers, and SSI recipients can use the current estimates, historical trends, and the calculator on this page to get a realistic sense of what their checks may look like in January 2027. Because the final figure depends on data not yet published, it is worth bookmarking this page and checking back as the announcement date approaches, since forecasts can still shift with each new inflation report.
