Medicare’s Impact on Social Security COLA

Medicare premium increases in 2026 may significantly reduce Social Security COLA gains for retirees.
Part B premiums rise $17.90 monthly, consuming much of the average 2.8% COLA increase.
Lower-income retirees not on Medicaid are most affected, as premiums directly reduce benefits.
Higher-income retirees pay more via IRMAA, though the impact is smaller relative to income.
Planning ahead, comparing plans, and using HSAs can help retirees manage healthcare costs.
