The 2027 social security cola forecast currently points to a benefit increase above the 2.8% adjustment received in 2026, but the official percentage has not yet been determined. As of August 24, 2026, the latest published estimates include a 3.5% projection from AARP and a 3.6% projection from the Senior Citizens League. The final COLA will depend on inflation readings for July, August and September 2026, with the Social Security Administration expected to announce the official adjustment in October.
The latest inflation data have moved expectations higher than the long-term assumptions used in the Social Security Trustees Report. The July Consumer Price Index showed that the CPI-W, the inflation measure used in the Social Security COLA formula, stood at 327.104. That July figure is the first of the three readings that will directly determine the 2027 adjustment.
For Social Security recipients, the next several weeks matter because two more CPI-W readings remain. August data are scheduled for release September 11, followed by September data on October 14. Until those numbers are available, no percentage can be treated as the official 2027 COLA.
Latest 2027 Social Security COLA Forecast
The most current forecasts released after the July inflation report put the expected 2027 increase in the mid-3% range.
AARP currently projects a 3.5% COLA for 2027. Its August 12 analysis said that such an adjustment would raise the average retired worker’s monthly benefit by about $73.
The Senior Citizens League has a slightly higher estimate of 3.6%. Its projection also followed the July inflation report and represented a decline from its earlier 3.8% estimate.
These estimates are not official government figures. They are current forecasts based on inflation data available before the complete third-quarter measurement period has finished.
The distinction is important. The Social Security Administration does not simply adopt an analyst’s forecast. It applies a specific statutory formula after all three months of the relevant quarter become available.
A separate estimate cited by the Committee for a Responsible Federal Budget puts the 2027 increase at approximately 3.2%, showing why the final figure remains uncertain even though the available forecasts are clustered above 3%.
The range of published estimates currently looks like this:
| Organization or source | Current 2027 estimate |
|---|---|
| AARP | 3.5% |
| Senior Citizens League | 3.6% |
| Committee for a Responsible Federal Budget estimate | About 3.2% |
| Social Security Administration official figure | Not yet announced |
The strongest takeaway is not that one particular percentage has been confirmed. Instead, the latest published forecasts indicate that analysts expect the 2027 adjustment to be higher than the 2.8% increase applied in 2026.
Why the 2027 COLA Is Not Official Yet
Social Security COLAs follow a formula based on the Consumer Price Index for Urban Wage Earners and Clerical Workers, commonly called CPI-W.
The calculation uses the average CPI-W for the third quarter of the current year. That means July, August and September are the three months that matter directly for the 2027 adjustment.
The three readings are averaged and compared with the third-quarter 2025 average that was used as the previous comparison point.
The third-quarter 2025 CPI-W average was 317.265. The three underlying monthly figures were 316.349 in July, 317.306 in August and 318.139 in September 2025.
The 2027 calculation therefore has a fixed starting point. What remains unknown is the average of the three CPI-W readings from July through September 2026.
That is why the July number alone cannot establish the final COLA.
July CPI-W Provides the First Key Reading
The Bureau of Labor Statistics released July 2026 inflation data on August 12.
The CPI-W reached 327.104 in July. The index was unchanged on a not-seasonally-adjusted basis from June, while the 12-month increase was 3.4%.
The July number matters because it is the first month inside the official third-quarter calculation period.
It also shows that the inflation environment remains stronger than the 2026 COLA would suggest. The 2026 COLA was 2.8%, while the July CPI-W was 3.4% higher than a year earlier.
However, the 3.4% annual CPI-W increase should not be confused with a 3.4% Social Security COLA. The COLA calculation does not simply use the annual inflation rate reported for July.
Instead, the Social Security formula compares quarterly CPI-W averages.
That difference explains why the final adjustment can differ from the inflation percentage appearing in monthly headlines.
What the July Number Means for Benefits
The July CPI-W reading places the 2027 calculation above the 2025 third-quarter reference average, but two more months must be added before the government can calculate the final percentage.
The 2025 third-quarter average was 317.265. July 2026’s CPI-W reading of 327.104 was therefore above that reference level.
This does not mean Social Security recipients have already earned a 3.1% COLA.
It means the first month of the three-month measurement period is now available.
The August and September figures could move the quarterly average higher or lower. The final percentage will reflect the complete July-through-September average.
That makes the September CPI-W release especially important.
August and September Inflation Data Are Still Missing
The next major date on the calendar is September 11, 2026, when the Bureau of Labor Statistics is scheduled to release the August CPI report.
The final data point will arrive on October 14, 2026, when September CPI information is scheduled for release.
Once September’s CPI-W is available, the three-month average can be calculated.
The Social Security Administration then determines the official COLA under the statutory formula.
This sequence explains why current forecasts can change quickly. A stronger August or September CPI-W reading would increase the three-month average, while weaker readings would put downward pressure on it.
For now, the July reading provides a firm first data point, but it does not settle the outcome.
How the 2027 Increase Compares With 2026
Social Security beneficiaries received a 2.8% COLA in 2026.
The increase applied to Social Security and Supplemental Security Income payments and represented the latest officially announced COLA. The Social Security Administration said the average retirement benefit increased by about $56 per month as a result of the 2026 adjustment.
The latest 2027 forecasts are higher.
A 3.5% adjustment would be 0.7 percentage point above the 2026 COLA. A 3.6% increase would be 0.8 percentage point higher.
That difference could matter for retirees who rely heavily on monthly Social Security income.
The size of the dollar increase, however, depends on each person’s actual benefit. Social Security does not give every recipient the same dollar increase because the percentage applies to individual benefit amounts.
What a 3.5% COLA Would Mean
A 3.5% COLA would increase a monthly Social Security benefit by 3.5%.
For example, someone receiving $2,000 per month would see a gross increase of $70, bringing the benefit to $2,070 before other deductions.
A $2,500 monthly benefit would increase by $87.50, while a $3,000 benefit would rise by $105.
These examples demonstrate how the percentage translates into dollars. They are not predictions of individual benefits.
AARP’s current 3.5% forecast estimates an increase of roughly $73 per month for the average retired worker.
The actual amount for an individual beneficiary will depend on the person’s benefit amount and any deductions that apply.
What a 3.6% COLA Would Mean
The Senior Citizens League’s current projection is slightly higher at 3.6%.
At that rate, a $2,000 monthly benefit would increase by $72.
A $2,500 benefit would rise by $90, while a $3,000 benefit would increase by $108.
Again, these calculations illustrate the effect of the percentage. They do not represent the final Social Security payment for any specific recipient.
The official percentage must come from the completed CPI-W calculation.
Why Current Forecasts Differ
Forecasts differ because analysts use the available inflation data and make different assumptions about where prices will settle during the remaining months.
The July data have already changed expectations.
CBS reported that the Senior Citizens League lowered its projection from 3.8% to 3.6%, while AARP reduced its estimate from 3.6% to 3.5% after the July CPI report.
That movement demonstrates how sensitive the forecast can be to each new inflation release.
It also explains why retirees should be cautious about headlines that present a forecast as though it were already official.
The only confirmed 2027 figure will come after the September CPI-W data become available and the Social Security Administration completes its calculation.
The 2026 Trustees Report Has a Lower Projection
The Social Security Administration’s 2026 Trustees Report provides another useful benchmark, although it should not be confused with the current inflation-based forecast.
Under the report’s intermediate assumptions, the estimated 2027 COLA is 2.4%. The same report estimates 2.4% adjustments for several following years under its long-range assumptions.
That 2.4% figure is a projection based on the Trustees Report’s economic assumptions. It is not the official 2027 COLA.
The latest CPI data have moved current outside forecasts above that level.
This difference is significant because the Trustees Report and current COLA forecasts serve different purposes. The Trustees Report looks at long-term Social Security finances and economic assumptions, while current COLA estimates respond to the inflation data that will feed directly into the statutory calculation.
When Will the Official 2027 COLA Be Announced?
The official 2027 COLA is expected in October 2026, after the September CPI report is released.
The Bureau of Labor Statistics has scheduled the September CPI release for October 14 at 8:30 a.m. Eastern Time.
The Social Security Administration has stated that it will announce the next COLA in October.
That means the final number is still several weeks away as of August 24.
The timing also gives beneficiaries a clear sequence to follow:
- August 12: July 2026 CPI data released.
- September 11: August 2026 CPI data scheduled.
- October 14: September 2026 CPI data scheduled.
- October: Social Security Administration expected to announce the 2027 COLA.
- January 2027: The new COLA is expected to appear in Social Security benefits payable for January.
The final payment timing can vary based on the type of Social Security or SSI benefit involved, but the annual COLA itself is determined from the third-quarter inflation calculation.
What Retirees Should Watch Next
For anyone following the 2027 adjustment, the next major number is the August CPI-W reading.
The September CPI-W will be even more important because it completes the three-month period used in the calculation.
Until then, the most useful approach is to distinguish between an estimate and an official determination.
The current forecasts from AARP and the Senior Citizens League both place the expected increase above 3%, while another estimate cited by the Committee for a Responsible Federal Budget is closer to 3.2%.
Those differences are normal before the full data set is available.
The latest information does establish one clear point: the 2027 COLA process is now underway, and July’s CPI-W reading has provided the first official inflation figure that counts toward the adjustment.
2027 Social Security COLA Forecast: What Is Confirmed Now
The current situation can be summarized simply:
| Key point | Latest confirmed status |
|---|---|
| 2026 COLA | 2.8% |
| 2025 Q3 CPI-W average | 317.265 |
| July 2026 CPI-W | 327.104 |
| AARP 2027 estimate | 3.5% |
| Senior Citizens League estimate | 3.6% |
| CRFB-cited estimate | About 3.2% |
| August CPI release | September 11, 2026 |
| September CPI release | October 14, 2026 |
| Official 2027 COLA | Not yet announced |
The July CPI-W reading has strengthened the case for an adjustment above 2026’s 2.8%, but the final percentage remains dependent on the next two CPI-W readings.
For beneficiaries planning their 2027 budgets, the most important dates are therefore September 11 and October 14. Those releases will provide the remaining inflation information needed to determine the final adjustment.
The latest 2027 social security cola forecast gives retirees a useful early indication, but the official number will not be known until the Social Security Administration completes the calculation after the third-quarter CPI-W data are available.
Stay tuned to the next inflation releases, and share your thoughts on where you expect the 2027 Social Security COLA to land.
