Millions of Americans receiving Social Security could see higher monthly payments in 2027, with current estimates pointing to a cost-of-living adjustment (COLA) of about 3.5% to 3.6%. If the forecast holds, the increase would be higher than the 2026 adjustment. However, the final figure has not yet been announced and will depend on additional inflation data.
Estimates
Independent Social Security and Medicare policy analyst Mary Johnson currently estimates that the 2027 Social Security COLA could be 3.5%. Her latest projection takes into account recently released consumer price data. She has also noted that changes in oil prices could affect inflation and cause the estimate to move in either direction.
The Senior Citizens League has also projected a 3.5% COLA, down from its earlier estimate of 3.6%. Based on the group’s latest calculation, the average monthly Social Security benefit could increase by approximately $67.90.
AARP has a slightly higher forecast. The organization recently raised its estimate to 3.6%, compared with 3.5% previously. At that level, the average retired worker could receive about $75 more per month.
These figures remain projections rather than official numbers. The final COLA will be determined after the government releases the inflation data needed for the annual calculation.
Payments
The dollar increase for each beneficiary would depend on their current monthly Social Security benefit. A percentage adjustment applies to the existing benefit, so people receiving larger payments would generally see a larger increase in dollar terms.
For example, a person receiving $2,000 per month would receive an additional $70 if the COLA were 3.5%. A 3.6% adjustment would increase the same benefit by $72.
| Current Monthly Benefit | 3.5% Increase | 3.6% Increase |
|---|---|---|
| $1,500 | $52.50 | $54 |
| $2,000 | $70 | $72 |
| $2,500 | $87.50 | $90 |
| $3,000 | $105 | $108 |
These examples are based only on the percentage increase. Actual payments can differ depending on a person’s benefit amount and other factors that affect their monthly payment.
History
The potential 2027 increase can be compared with recent Social Security adjustments. In 2026, Social Security and Supplemental Security Income beneficiaries received a 2.8% increase.
COLA figures have varied considerably over the past decade. The adjustment was 0% in 2016, while the 2023 COLA reached 8.7%, reflecting the period of elevated inflation.
The Social Security Administration says the average COLA over the past decade has been about 3.1%. A 3.5% to 3.6% adjustment would therefore be above that recent average.
The size of the COLA is intended to help benefits keep pace with inflation. However, the impact on household budgets depends on how prices for necessities such as food, housing, healthcare and energy change over the same period.
Inflation
The annual Social Security COLA is based on a specific measure of inflation called the Consumer Price Index for Urban Wage Earners and Clerical Workers, or CPI-W.
The calculation uses inflation readings from the third quarter of the year. The Social Security Administration compares the average CPI-W for July, August and September with the corresponding third-quarter average from the previous year.
Recent inflation figures have provided an indication of where the 2027 COLA could stand. The CPI-W increased 3.5% over the 12 months through August, while the broader Consumer Price Index increased 3.4% during the same period.
Energy prices are one factor that could affect future inflation readings. Oil prices can change relatively quickly, influencing gasoline costs and other prices throughout the economy.
Timing
The September inflation report will be an important part of the 2027 COLA calculation because it completes the third-quarter data used by the Social Security Administration.
The agency generally announces the official COLA for the following year in October. Until then, estimates from analysts and advocacy groups can change as new inflation information becomes available.
For Social Security recipients, this means the current 3.5% to 3.6% range should be treated as a forecast rather than a confirmed increase.
Outlook
A 3.5% to 3.6% Social Security COLA would raise monthly benefits for millions of recipients in 2027. Depending on the final percentage and the size of an individual’s benefit, the increase could amount to several dozen dollars per month. The September inflation data will help determine the final calculation, with the Social Security Administration expected to announce the official 2027 COLA in October.
