The social security cola 2027 announcement date is not here yet, but the timeline is becoming clearer. The Social Security Administration (SSA) has confirmed that the next cost-of-living adjustment will be announced in October 2026, and the Bureau of Labor Statistics (BLS) has scheduled the September Consumer Price Index report for October 14, 2026, at 8:30 a.m. Eastern Time. That September inflation report supplies the final month of data needed for the 2027 COLA calculation.
For millions of Americans receiving Social Security, the October announcement will determine how much their monthly benefits increase in 2027. However, no official 2027 percentage has been announced as of August 28, 2026.
Current private-sector estimates point to a 2027 increase of roughly 3.5% to 3.6%. Those figures are forecasts, not the official COLA. The final adjustment will depend on the inflation data used under federal law.
When Is the 2027 Social Security COLA Announcement?
The SSA’s official COLA information page currently states that the next COLA will be announced in October 2026. It does not yet list a specific official announcement date for the 2027 adjustment.
The key date on the federal economic calendar is Wednesday, October 14, 2026. That is when the BLS is scheduled to release the September 2026 Consumer Price Index at 8:30 a.m. Eastern Time.
The September CPI report matters because the Social Security COLA calculation uses inflation data from July, August and September. September is therefore the final month required to complete the calculation.
Based on the current federal release schedule and the SSA’s statement that the next COLA will be announced in October, October 14 is the key date beneficiaries should watch. However, it is important to distinguish between the scheduled CPI release date and an independently confirmed SSA announcement date.
The SSA has not yet published a 2027 COLA announcement stating that October 14 is the official announcement date. Therefore, reports describing October 14 as the final SSA announcement date should be treated as an expected date until the agency confirms it.
Why October Is So Important for Social Security Benefits
The Social Security COLA is not simply selected by the SSA. Federal law establishes the formula used to determine the annual adjustment.
The calculation is tied to the Consumer Price Index for Urban Wage Earners and Clerical Workers, commonly called the CPI-W. The relevant comparison uses the average CPI-W for the third quarter of the current year against the corresponding third-quarter average from the previous year.
The third quarter consists of:
- July
- August
- September
July and August inflation data will be available before the September report. The September figure completes the three-month period used in the calculation.
That is why the October CPI release is so important. Once the September data become available, the complete third-quarter figures can be used to determine the adjustment.
The process also explains why the final 2027 percentage cannot be confirmed in August.
What the Latest Inflation Data Show
The most recent national CPI report available as of August 28 covers July 2026. The BLS reported that the CPI for all urban consumers increased 0.1% in July on a seasonally adjusted basis after declining 0.4% in June. Prices were 3.4% higher over the 12 months ending in July.
Core inflation, which excludes food and energy, increased 0.2% in July and was up 2.5% over the previous 12 months.
The July report also showed significant differences among major categories. Energy prices fell 1.5% during the month, while the energy index remained 14.7% higher than a year earlier. Shelter increased 0.1% in July and accounted for roughly two-thirds of the monthly increase in the overall CPI.
These figures provide important information about inflation, but they do not establish the 2027 Social Security increase by themselves.
August and September CPI-W data still have to be incorporated into the official calculation.
Current Estimates for the 2027 COLA
Although the official number remains pending, several organizations have released updated estimates.
AARP currently projects a 3.5% COLA for 2027 based on its analysis of current inflation trends. AARP said that such an increase would add about $73 per month to the average retired worker’s benefit.
The Senior Citizens League has projected a 3.6% increase based on the latest available inflation data. CBS News reported that the group’s estimate fell from 3.8% after July inflation data were released.
These estimates should not be confused with the official government determination.
The final COLA could be higher or lower because August and September CPI-W readings are still outstanding.
A simple comparison of the current projections looks like this:
| Organization or source | Current 2027 estimate | Status |
|---|---|---|
| AARP | 3.5% | Forecast |
| Senior Citizens League | 3.6% | Forecast |
| Social Security Administration | Not announced | Official figure pending |
| 2026 COLA | 2.8% | Official |
The difference between the forecasts is small, but even a few tenths of a percentage point can affect monthly benefits for people receiving Social Security.
The 2026 COLA Provides the Current Baseline
The current official COLA is 2.8% for 2026.
The SSA announced the 2026 adjustment on October 24, 2025. The increase applied to Social Security benefits beginning in January 2026, while increased SSI payments began on December 31, 2025.
The SSA said the 2026 increase affected nearly 71 million Social Security beneficiaries. It also estimated that the average Social Security retirement benefit would increase by about $56 per month.
That 2.8% adjustment serves as the latest confirmed benchmark while beneficiaries wait for the 2027 figure.
If the 2027 COLA ultimately comes in at 3.5% or 3.6%, it would be higher than the 2026 adjustment. But the final percentage cannot be stated as fact until the government completes the calculation.
What Happens Before the Official Announcement
The remaining timeline is relatively straightforward.
The BLS is scheduled to release the August 2026 CPI report on September 11, 2026, at 8:30 a.m. Eastern Time. That report will provide another month of inflation data for the third-quarter calculation.
The September CPI report is scheduled for October 14, 2026, at 8:30 a.m. Eastern Time.
Once the September data are available, the three-month third-quarter average can be completed.
The SSA’s official COLA page says the next adjustment will be announced in October 2026.
For that reason, October is the critical month for beneficiaries waiting for the official 2027 increase.
Will the 2027 COLA Be 3.5% or 3.6%?
There is no official answer yet.
The current estimates of 3.5% and 3.6% reflect available inflation data. They are useful indicators, but they do not replace the statutory calculation.
AARP’s 3.5% estimate is based on current inflation trends, while the Senior Citizens League’s latest projection is 3.6%.
The remaining inflation readings could change either forecast.
For Social Security recipients, this distinction is important. A forecast can change before the government publishes the final number. Therefore, beneficiaries should avoid treating an estimate as a guaranteed increase.
The official percentage will come after the required inflation data are available and the statutory formula is applied.
When Would the 2027 Increase Begin?
The COLA announced in October 2026 will affect Social Security benefits in 2027.
The SSA explains that its COLA figures are associated with the calendar year in which the adjustment becomes effective. The 2027 increase will therefore affect benefits payable in 2027 rather than changing payments immediately after the October announcement.
SSI payments can follow a different payment calendar because SSI payments are generally issued at the beginning of the month.
The exact payment date can depend on the type of benefit and an individual’s payment schedule. The important point for the COLA announcement is that October establishes the annual adjustment, while the increased Social Security benefit is reflected in payments beginning in 2027.
What Beneficiaries Should Watch for in October
People waiting for the 2027 COLA should focus on three pieces of information.
First, watch the September CPI release from the BLS. That report is scheduled for October 14 and provides the final inflation data needed for the third-quarter calculation.
Second, look for the SSA’s official announcement. The agency has already confirmed that it will announce the next COLA in October 2026.
Third, wait for the final percentage before calculating a new monthly benefit.
Current estimates are useful for planning, but they remain estimates until the official number is released.
2027 COLA Announcement Date: What Is Confirmed Right Now?
As of August 28, 2026, the confirmed facts are clear:
- The 2027 Social Security COLA has not yet been officially announced.
- The SSA says the next COLA will be announced in October 2026.
- The BLS has scheduled the September 2026 CPI release for October 14, 2026, at 8:30 a.m. ET.
- The September inflation figure is the final piece of the third-quarter CPI-W data used in the COLA calculation.
- Current outside estimates range from about 3.5% to 3.6%.
- The official 2027 percentage remains pending.
The most important distinction is between an expected date and an officially announced date. October 14 is the scheduled date for the September CPI release, but the SSA has not yet published a 2027 COLA notice formally identifying that date as its announcement date.
Bottom Line
The social security cola 2027 announcement date is approaching, but the official increase is still several weeks away. The SSA has confirmed that the 2027 COLA will be announced in October 2026, while the BLS has scheduled the September CPI report for October 14 at 8:30 a.m. ET. That report is expected to provide the final inflation data needed for the annual calculation.
Current forecasts suggest an increase around 3.5% to 3.6%, but those numbers can still change. The final figure will depend on the remaining inflation data and the formula required under federal law.
For now, October 2026 is the key month to watch, with October 14 standing out as the scheduled release date for the inflation report that completes the calculation.
