Key Points
Projections for Social Security’s 2027 cost‑of‑living adjustment have slipped as recent government inflation data show a modest slowdown. While a 3.9% increase was once expected, analysts now anticipate a lower figure.
Predictions Vary Widely
Despite agreement that 2027’s COLA will exceed the 2.8% rise slated for 2026, forecasts differ. Recent estimates include:
- AARP: 3.5% COLA.
- Senior Citizens League (TSCL): 3.6% COLA.
- Committee for a Responsible Federal Budget (CRFB): 3.2% COLA.
The CRFB notes that higher adjustments can provide short‑term relief to seniors but add pressure to a Social Security trust fund projected to become insolvent in about six years.

How COLAs Are Calculated
The annual Social Security COLA is legally based on the Bureau of Labor Statistics’ inflation figures for July, August, and September, using the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI‑W). This measure tracks price changes for goods and services typically purchased by urban wage earners and office workers.
The choice of CPI‑W has drawn criticism. Senior advocacy groups such as AARP and the Senior Citizens League have long pushed for the Consumer Price Index for the Elderly (CPI‑E), arguing it better reflects seniors’ spending patterns. Adopting CPI‑E would require an act of Congress.
A recently reintroduced bill would mandate that the government apply whichever index—CPI‑W or CPI‑E—produces the larger adjustment. The proposal remains pending and does not affect 2027 benefits, though it signals possible future changes.
What Seniors Should Keep in Mind
Because inflation remains volatile, the 2027 COLA is still uncertain. Historically, the final percentage is not announced until mid‑October. Beneficiaries are advised to treat current forecasts as provisional and to plan for a range of possible outcomes.
