Social Security recipients are getting a much clearer picture of what their benefits could look like in 2027.
After the latest inflation data, AARP is projecting a 3.6% Social Security cost-of-living adjustment (COLA) for 2027, while The Senior Citizens League is forecasting a slightly lower 3.5% increase.
Neither number is official yet.
But with two of the three months used to calculate the annual adjustment now in the books, the range gives retirees and other Social Security recipients a useful preview of what could be coming.
What Is the Latest 2027 Social Security COLA Estimate?
The latest forecasts are clustered within a very narrow range.
Following the August inflation report, AARP’s estimate increased to 3.6%, up from its previous 3.5% projection.
At the same time, The Senior Citizens League is forecasting a 3.5% COLA.
That means current estimates differ by only one-tenth of a percentage point.
If either projection is close to the final number, the 2027 adjustment would be larger than the 2.8% COLA beneficiaries received for 2026.
It would also be the largest annual COLA since 2023, when benefits rose 8.7%.
The increase would not represent extra money in the same way that a pay raise might. Social Security’s COLA is designed to help benefits keep pace with rising consumer prices.
And those prices have continued to climb.
Why the 2027 COLA Isn’t Official Yet
Social Security does not determine the annual COLA using the inflation rate from a single month.
Instead, the calculation is based on the Consumer Price Index for Urban Wage Earners and Clerical Workers, better known as the CPI-W.
According to the Social Security Administration, annual cost-of-living adjustments are tied to changes in this inflation index.
For the 2027 COLA, the key period is the third quarter of 2026:
- July
- August
- September
The average CPI-W for those three months is compared with the corresponding third-quarter average used for the previous COLA.
July and August are already known.
The Senior Citizens League reported that the CPI-W was up 3.4% from a year earlier in July and 3.5% in August.
That leaves September as the final piece of the calculation.
The September inflation report is scheduled for October 14, 2026, which is also when the official 2027 Social Security COLA is expected to be announced.
Until then, 3.5% and 3.6% should be treated as projections—not guaranteed increases.
How Much Could Your Social Security Check Increase?
The actual dollar increase depends on the size of your benefit.
Here’s a simple illustration of what a 3.5% or 3.6% increase could look like before deductions:
| Current Monthly Benefit | Increase at 3.5% | Increase at 3.6% |
|---|---|---|
| $1,000 | $35.00 | $36.00 |
| $1,500 | $52.50 | $54.00 |
| $2,000 | $70.00 | $72.00 |
| $2,500 | $87.50 | $90.00 |
| $3,000 | $105.00 | $108.00 |
For someone receiving $2,000 per month, for example, a 3.6% adjustment would amount to approximately $72 more per month, or roughly $864 over a full year before considering deductions or other adjustments.
Someone receiving $2,500 per month could see approximately $90 more per month at 3.6%.
These calculations are useful estimates rather than exact benefit quotes. Social Security determines each person’s actual benefit amount, and the amount deposited into a bank account can also be affected by deductions.
