The Social Security Administration's annual cost-of-living adjustment will go up by 2.8% in 2026, translating to an average increase of more than $56 for retirees every month, agency officials said Friday. The benefits increase for nearly 71 million Social Security recipients will go into effect beginning in January. The cost-of-living adjustment, or COLA, for retirees and disabled beneficiaries is financed by payroll taxes collected from workers and their employers, up to a certain annual salary, which is slated to increase to $184,500 in 2026, from $176,100 in 2025.
