In 2025, Social Security benefits, including SSDI and Supplemental Security Income (SSI) payments, will increase by 2.5% due to the cost-of-living adjustment (COLA). The COLA is applied annually based on changes in the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W), which measures inflation.
Keep in mind, any of this is subject to change going into 2025.
