How the Social Security Administration Calculates COLA
The SSA evaluates CPI-W inflation figures across the third quarter (July, August, and September).

Key Factors Affecting Net Payments
Medicare Part B Premiums: Standard Medicare Part B monthly premiums are automatically deducted from most Social Security checks. Any rise in Medicare premiums can offset part of the net dollar gain from the COLA.
Tax Thresholds: Higher gross monthly benefits can push total retirement income past federal tax thresholds, subjecting a higher portion of Social Security income to taxation.
Notification Access: Beneficiaries can check their personalized updated benefit amounts in December through their secure online personal Social Security portal or via mailed notices.
