1. Current Forecast Range: 3.4% to 3.6%
Most analysts now project a COLA increase for 2027 between 3.4% and 3.6%, reflecting cooling inflation over the summer of 2026.
- AARP estimates a 3.6% adjustment.
- Senior Citizens League projects 3.5%.
- Additionally, independent analyst Mary Johnson estimates 3.4% based on July CPI‑W data.
Also, these projections suggest a meaningful COLA increase for 2027, larger than the 2.8% adjustment retirees received in 2026.
2. Why the COLA Increase for 2027 Is Trending Higher
The COLA increase for 2027 is tied to inflation data from July, August, and September 2026, with August CPI‑W already showing a 3.5% year‑over‑year rise. Moderating inflation earlier in the year pulled projections down from earlier 4%+ estimates, but current data still supports a solid COLA.
3. What a 3.4%–3.6% COLA Means for Retirees
A COLA increase in this range would raise the average monthly Social Security benefit:
- Additionally the average benefit (2026): $2,071
- Also at 3.5%, the average benefit would rise by about $72–$75 per month, reaching roughly $2,143–$2,146.
This would be the largest COLA increase since 2023, helping retirees offset rising costs though many analysts note that healthcare and housing inflation may still outpace benefits.
4. When the Official Number Will Be Announced
The Social Security Administration will release the official COLA on October 14, 2026, after September inflation data is finalized.
Bottom Line
The projected increase likely between 3.4% and 3.6% signals a stronger‑than‑average adjustment driven by persistent inflation. While helpful for retirees, the final number will depend on September CPI‑W data, making October’s announcement crucial for 2027 financial planning.
