The 2.8% COLA Preview in December 2025: Early Boost for SSI, Full Impact in January
The crown jewel of December 2025 Social Security changes is the 2.8% COLA announcement from October 2025, calculated via the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W), promising an average $56 monthly increase for retirement benefits starting January 2026.
This adjustment—up from 2025’s 2.5%—reflects Q3 2025’s 2.76% CPI-W rise, rounded to the nearest tenth, ensuring benefits keep pace with everyday costs like a $48 grocery bump for retirees.
For SSI’s 7.5 million recipients, December brings the magic: The regular December payment hits December 1 at 2025 rates ($943 single/$1,415 couples), but January’s COLA-adjusted amount advances to December 31 due to New Year’s Day holiday—creating a “double-check” month without extras, just timing convenience.
Retirement, SSDI, and survivors see no December hike—their January payments rise seamlessly. Notices mail early December or hit mySocialSecurity accounts by November 19 if you opt digital—averaging $1,920 to $2,056 for retirees. Pro tip: Recalculate Medicare premiums (Part B up $10 to $185.70) from deductions—net gains vary.
