Social Security COLA 2027: Social Security beneficiaries in the United States could see their monthly payments increase by around 3.5% in 2027, according to the latest forecast from The Senior Citizens League (TSCL).
The estimate is slightly lower than the group’s previous forecast of 3.6%. However, the 3.5% figure is not yet official. The final 2027 Cost-of-Living Adjustment (COLA) will be announced by the Social Security Administration (SSA) on October 14, 2026, after September inflation data is released by the Bureau of Labor Statistics.
2027 Social Security COLA Could Be 3.5%
TSCL’s latest projection puts the 2027 Social Security COLA at 3.5%. The estimate is also broadly in line with a projection from independent Social Security and Medicare policy analyst Mary Johnson, who similarly estimated that the increase could be 3.5%.
The final percentage, however, could still change depending on inflation data released before the official announcement.
TSCL Executive Director Shannon Benton said short-term economic changes that affect inflation could influence the final calculation.
When Will the Official 2027 COLA Be Announced?
The Social Security Administration is expected to announce the official 2027 COLA on October 14, 2026.
The calculation depends on inflation data from the third quarter. The September CPI-W figure is particularly important because the COLA calculation uses the CPI-W readings for July, August and September.
Two of those three figures were already available at the time of the latest TSCL forecast.
After the official announcement, Social Security recipients will receive personalized notices showing their new benefit amounts in December.
How Much Could the Average Social Security Check Increase?
If the projected 3.5% COLA becomes the final figure, the average retiree’s monthly Social Security payment could increase by approximately $67.90.
Based on the figures cited in the report:
- Current average monthly benefit: $1,940.08
- Estimated 3.5% increase: $67.90
- Estimated new monthly benefit: $2,007.98
That would mean roughly $814.80 more per year if the beneficiary received the same monthly amount throughout the year.
What If Your Monthly Benefit Is $2,071?
The amount added to a Social Security check depends on the individual’s current benefit.
For example, if someone currently receives $2,071 per month, a 3.5% increase would work out to approximately $72.49 more per month.
That would bring the estimated monthly payment to about $2,143.49.
Calculation:
$2,071 × 3.5% = approximately $72.49
$2,071 + $72.49 = approximately $2,143.49
The actual increase will depend on the official COLA and the recipient’s individual benefit amount.
Why Does Social Security Get a COLA?
The annual Cost-of-Living Adjustment is designed to help Social Security benefits keep pace with changes in consumer prices.
COLAs are calculated using the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W), which is published monthly by the Bureau of Labor Statistics (BLS).
When the relevant inflation measure increases, Social Security benefits are adjusted accordingly under the applicable calculation.
How Is the Social Security COLA Calculated?
The calculation compares the average CPI-W for the third quarter of the current year with the average CPI-W for the third quarter of the last year in which a COLA became effective.
If there is an increase, the resulting percentage is rounded to the nearest tenth of one percent.
If there is no increase, or the rounded increase is zero, there is no COLA for that year.
Inflation Remains Important for the 2027 COLA
The latest forecast comes after the release of August inflation data.
According to the figures cited in the report, consumer prices were up 3.4% year over year, while core inflation increased 0.3% month over month.
Energy prices are also being closely watched because sudden changes in fuel costs can influence inflation readings and, consequently, COLA expectations.
The final September inflation data will therefore be important in determining whether the 3.5% forecast holds.

Why a 3.5% COLA May Still Feel Different to Seniors
A 3.5% increase would represent a significant adjustment, but the actual impact can vary from one household to another.
TSCL has pointed out that older Americans often spend their money differently from people who are still working. Expenses such as healthcare, housing and other essential costs can represent a different share of a retiree’s budget.
Because the COLA is based on CPI-W, the inflation measure may not perfectly reflect the spending patterns of every Social Security recipient.
As a result, even when benefits increase, some seniors may still feel pressure from rising household expenses.
How to Calculate Your Estimated 2027 Benefit
Beneficiaries can make a simple estimate using their current monthly Social Security payment.
Formula:
Current monthly benefit × 1.035 = estimated monthly benefit
For example:
| Current Monthly Benefit | Estimated 3.5% Increase | Estimated New Benefit |
|---|---|---|
| $1,500 | $52.50 | $1,552.50 |
| $1,750 | $61.25 | $1,811.25 |
| $1,940.08 | $67.90 | $2,007.98 |
| $2,071 | $72.49 | $2,143.49 |
| $2,500 | $87.50 | $2,587.50 |
| $3,000 | $105.00 | $3,105.00 |
These figures are illustrations based on a 3.5% assumption, not official 2027 benefit amounts.
How to Check Your Personalized Social Security Benefit
Beneficiaries can use their account on SSA.gov to view their Social Security information and estimate retirement benefits.
Personalized notices containing the new benefit amounts are expected to be available in December after the official COLA announcement.
What Happens Next?
The most important date for beneficiaries is October 14, 2026, when the Social Security Administration is expected to release the official 2027 COLA.
Until the September inflation data is incorporated into the calculation, the current 3.5% estimate remains a forecast rather than a confirmed increase.
If the projection ultimately becomes the official COLA, beneficiaries would see their monthly Social Security payments adjusted according to the 3.5% increase.
