Social Security beneficiaries are projected to receive a cost-of-living adjustment (COLA) between 3.4 percent and 3.6 percent for 2027, marking the largest increase in several years yet reflecting persistent inflation rather than real economic gains.
The 2027 figure represents a meaningful jump from recent years—the 2025 COLA was 2.5 percent and 2026 came in at 2.8 percent—but the gains are almost entirely erosion recovery. At 3.6 percent, the average monthly retirement benefit of $1,937.53 would increase by roughly $70, a nominal cushion that translates to near-zero real improvement once price growth is factored in.
The official 2027 COLA will be finalized in October by the Social Security Administration, calculated using third-quarter data from the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W). Early projections shifted materially as inflation moderated. In May 2026, when CPI-W surged 0.7 percent month-over-month and 4.4 percent year-over-year—the fastest pace since April 2023—independent analyst Mary Johnson raised her 2027 forecast to 4.7 percent. June CPI data, driven by energy price declines, cooled annual growth to 3.5 percent. Johnson lowered her estimate by a full percentage point to 3.7 percent. After July CPI data released August 12, she cut it again to 3.4 percent, citing inflation moderation.
The Senior Citizens League adjusted its estimate down to 3.6 percent from 3.8 percent. AARP, using Federal Reserve inflation projections, released an estimate of 3.5 percent.
The consensus range of 3.4 to 3.6 percent exceeds both the 2026 COLA (2.8 percent) and the long-term average (2.6 percent), though it aligns with the Social Security Administration's 10-year historical average of 3.1 percent. The larger nominal adjustment masks a structural constraint: benefits adjusted for inflation-adjusted terms will remain essentially flat in real purchasing power.
