Key drivers
- May 2026 CPI-W already 3.645 percent above the 2025 Q3 CPI-W base average
- Energy inflation lifted near-term CPI but may partly reverse before Q3
- Core CPI is lower than headline, limiting persistence
- SSA formula rounds the Q3 CPI-W increase to the nearest tenth
- September 2026 CPI release fixes the last resolving input on October 14, 2026
Resolution

- Social Security Administration latest Cost-of-Living Adjustment page
- expected
- October 14, 2026
- rule
- Resolve to SSA's first official published COLA for Social Security benefits beginning with December 2026 benefits payable in January 2027. Use the percent adjustment rounded to the nearest tenth of one percent under the SSA CPI-W formula comparing the average CPI-W for July, August, and September 2026 with the average CPI-W for July, August, and September 2025. Ignore later revisions or corrections unless the official resolver policy explicitly treats the first print as invalid.
