Approximately 76 million Americans will see a 3.6 percent boost in their monthly Social Security benefits and Supplemental Security Income (SSI) payments beginning in 2027, the Social Security Administration (SSA) announced Wednesday.
The cost-of-living adjustment (COLA) translates to an average increase of roughly $75 per month for retired workers starting in January 2027.
Key Details & Important Timelines
-
Who is Affected: Nearly 72 million Social Security beneficiaries and about 7.3 million SSI recipients.
-
Payment Start Dates:
-
SSI Beneficiaries: Updated payment amounts will take effect on December 31, 2026.
-
Social Security Recipients: Increased monthly benefit checks will begin in January 2027.
-
-
Early Access via Digital Notice: Recipients who create or log into a personal my Social Security account and sign up for paperless notices by November 18, 2026, can view their personalized COLA notice online up to three weeks earlier than those receiving notices by mail. Official paper notices will be mailed throughout December for individuals who do not opt into digital communications.
How the Increase Is Calculated
Under federal law, annual COLAs are determined by changes in the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W), compiled by the Department of Labor’s Bureau of Labor Statistics. The 2027 adjustment compares the average third-quarter CPI-W numbers from 2026 to the same period in 2025.
The 3.6 percent rate represents a step up from recent adjustments—such as the 2.8 percent increase implemented in 2026—reflecting persistent price pressures across housing, everyday consumer items, and broader cost trends.
Additional 2027 Changes
Alongside the COLA increase, the Social Security Administration noted other automatic adjustments tied to average wage growth:
-
Taxable Maximum Increase: The maximum amount of earnings subject to the Social Security payroll tax will rise to $192,300 in 2027, up from $184,500 in 2026.
-
Medicare Details: Beneficiaries enrolled in Medicare can check their personalized 2027 benefit updates and premium adjustments through the my Social Security Message Center starting in late November.
