The Social Security COLA 2027 forecast is pointing toward a bigger increase than beneficiaries received this year. The latest projections put the 2027 cost-of-living adjustment at about 3.5% to 3.6%, although the final number will depend on September inflation data.
AARP currently projects a 3.6% COLA, while the Senior Citizens League (TSCL) puts its estimate at 3.5%. Both forecasts are above the 2.8% COLA for 2026.
The official number is expected on October 14, 2026, when the Social Security Administration has the final inflation data needed to calculate the adjustment.
What is the Social Security COLA 2027 Forecast?
The latest Social Security COLA 2027 forecast is 3.5% to 3.6%, according to recent projections from AARP and the Senior Citizens League.
The range has moved considerably during 2026 as inflation readings changed.

A 3.6% increase would be the largest annual Social Security adjustment since 2023, when benefits rose 8.7%.
The forecast is still an estimate. The final cost-of-living adjustment cannot be calculated until September’s inflation figure is available.
Why Could Social Security Benefits Increase in 2027?
The main reason is inflation.
The Social Security Administration bases the annual COLA on the Consumer Price Index for Urban Wage Earners and Clerical Workers, or CPI-W. It compares the average CPI-W for July, August and September with the corresponding period from the previous year.
Recent inflation readings have kept the 2027 forecast above the 2026 increase.
In August, US consumer prices rose 3.4% over the previous year, according to the Bureau of Labor Statistics. AARP said the CPI-W, the specific inflation measure used for the COLA, was up 3.5% year over year in August.
For Social Security recipients, that matters because the COLA is designed to help benefits keep pace with rising prices.
How Much Could Social Security Benefits Increase in 2027?
A 3.6% Social Security COLA would increase the average retired worker’s monthly benefit by about $75. This calculation is based on the current average payment level.
As the Social Security Administration, the mean monthly benefit for retired workers was $2,085.98 in July 2028.
At different COLA levels, the increase would look approximately like this:
|
COLA |

Approx. new monthly benefit |
|
3.4% |
$71 |
$2,157 |
|
3.5% |
$73 |
$2,159 |
|
3.6% |
$75 |
$2,161 |
These figures are illustrations. Individual Social Security payments vary depending on a person’s benefit amount.
AARP’s estimate, using the average retired-worker benefit of $2,071 at the start of 2026, puts a 3.6% increase at about $75 more per month.
When Will the 2027 Social Security COLA Be Announced?
The 2027 Social Security COLA is expected to be announced on October 14, 2026.
The timing is tied to the release of September inflation data. The Social Security Administration needs the July, August and September CPI-W figures to complete the calculation.
That means the current forecast could still change slightly if September prices rise or fall more than expected.
For beneficiaries, the increase will take effect with January 2027 Social Security payments.
How is the Social Security COLA Calculated?
The Social Security COLA is calculated using the third-quarter CPI-W average.
The process is straightforward:
- The government measures CPI-W in July, August and September.
- Those three-monthly figures are averaged.
- The average is compared with the third-quarter average from the previous year.
- The percentage increase becomes the Social Security COLA.
- The final figure is rounded to the nearest tenth of a percentage point.
The calculation has been used for Social Security COLAs since 1983.
This also explains why forecasts can change from month to month. Until September’s number is known, the final calculation is incomplete.
How Does the 2027 Forecast Compare with Recent COLAs?
The projected 2027 increase would be higher than the last two annual adjustments.
Recent Social Security COLAs include:
- 2023: 8.7%
- 2024: 3.2%
- 2025: 2.5%
- 2026: 2.8%
- 2027 forecast: about 3.5%–3.6%
The 2026 COLA was based on the increase in CPI-W between the third quarters of 2024 and 2025.
If the current 2027 forecast holds, beneficiaries would receive a larger increase than they did this year.
Will a Higher COLA Give Retirees More Purchasing Power?
A higher COLA means a larger Social Security check, but it does not necessarily mean retirees will feel substantially better off.
That is because the COLA follows inflation rather than creating additional purchasing power.
For many older Americans, household budgets are particularly sensitive to:
- Groceries
- Housing
- Energy
- Healthcare
- Insurance
- Prescription medications
AARP notes that many older adults are feeling continued pressure from these expenses. Its research also found that 74% of current Social Security beneficiaries had made financial changes because rising costs had outpaced their benefit payments.
This is one reason the size of the COLA attracts so much attention each year.
Why is the Social Security COLA Important?
Social Security is a source of retirement income for millions of Americans. The annual cost-of-living adjustment tells us how much that income will change as prices go up.
Besides the current inflation rate and household expenses being above the Federal Reserve’s 2% target over the long-term which is causing an issue for fixed-income households in the US, Social Security beneficiaries in 2027 may also need to watch their benefits closely if inflation stays at the level, it’s been for so long.
Even though the current projection is not entirely positive, still it does indicate some good news to expect from the coming year, and those benefiting from such social programs will only be able to find out the full extent of the change on October announcement day as of right now.
What Happens Next for Social Security Recipients?
The next important date is October 14, 2026.
Until then, retirees and other beneficiaries can use the 3.5%–3.6% range as a planning estimate, rather than treating it as the final number.
The key dates are:
- September 2026: Final month of inflation data used in the COLA calculation
- October 14, 2026: Expected official COLA announcement
- December 2026: Updated benefit information becomes available to beneficiaries
- January 2027: New COLA-adjusted Social Security payments begin
Conclusion
The Social Security COLA 2027 forecast currently sits around 3.5% to 3.6%, which would be higher than the 2.8% increase beneficiaries received in 2026.
A 3.6% adjustment would add about $75 a month to an average retired worker’s benefit, although the actual increase will depend on each person’s current payment.
The final answer is now close. With only September inflation data left to factor in, the Social Security Administration is expected to announce the official 2027 cost-of-living adjustment on October 14.
