The U.S. Social Security Administration announced the annual cost-of-living adjustment, known as COLA, at 2.8% for 2026. The increase takes effect in January and raises average retirement benefits by about 56 dollars per month. The measure affects approximately 75 million beneficiaries of programs such as Social Security and Supplemental Security Income.
The calculation relies on the consumer price index for urban wage earners and clerical workers, or CPI-W, comparing the third quarter of 2024 with that of 2025. Over the past 20 years, the average COLA stood at 2.6%, according to data from a nonpartisan senior group. In 2025, the adjustment reached 2.5%.
- Multiply the current monthly benefit by 0.028 to estimate the increase.
- Account for deductions such as Medicare Part B premiums.
- Opt for federal tax withholding at fixed rates of 7%, 10%, 12%, or 22%.
Annual adjustment calculation
The COLA reflects the percentage change in CPI-W between specific quarters. Federal authorities apply the formula to preserve the purchasing power of benefits.
In 2023, the index hit 8.7%, the highest in four decades, due to post-pandemic inflation. In subsequent years, values approached the historical average.
Impact on beneficiaries
Around 75 million people receive monthly payments from these programs. The average increase of 56 dollars applies to retirees, with variations based on the original benefit amount.
Medicare Part B premiums may rise 11.6%, to 206.50 dollars monthly, according to projections. Higher-income beneficiaries face additional costs via IRMAA.
Deductions and planning
Federal tax withholding applies if combined income exceeds 25 thousand dollars for singles or 32 thousand for married couples filing jointly. Combined income adds half of benefits plus other sources.
Beneficiaries select fixed rates for withholding. Factors like medical premiums reduce the net amount received.
Adjustment history
The 2026 COLA aligns with expert forecasts of 2.7% to 2.8%. The 2024 adjustment stood at 3.2%, followed by 2.5% in 2025.
Over the past 20 years, the 2.6% average demonstrates relative stability. The formula uses a subset of the consumer price index.
Premium projections
The standard Part B monthly rate may increase by 21.50 dollars. Automatic deductions occur directly from benefit checks.
Adjustments account for inflation and medical costs. Beneficiaries monitor official announcements for planning.
Individual estimate
Simple multiplication by the 0.028 factor provides the expected addition. Agency online tools assist with accurate calculations.
Other elements, such as optional taxes, influence the final payment. Annual adjustments ensure adaptation to the economy.
