Analysts now estimate the Social Security COLA for 2027 at about 3.6%, according to recent projections that cite slowing inflation and updated CPI readings.
Multiple forecast pieces report a roughly 3.6% cost-of-living adjustment for 2027; one headline reads, ‘Social Security 2027 COLA projected at 3.6%, largest boost since 2023.’

The estimate is a projection, not the official number. The Social Security Administration traditionally announces the annual COLA in mid-October; one report notes the official 2027 COLA is “set to be announced Oct. 14.”
Analysts arrive at COLA projections by tracking the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) over the 12-month measurement period used to calculate benefits. Forecast stories attribute the latest 3.6% figure to cooler inflation readings through early September.

For beneficiaries, a 3.6% COLA would raise monthly payments modestly; earlier coverage estimated a roughly $73 monthly increase for a typical retiree under similar percentage projections.
Because these are forecasts, the final COLA will match the SSA’s official October announcement and the CPI-W measurement for the period the agency uses to set the adjustment.
