How does the annual COLA increase affect my benefit?
2026 Social Security Cost-of-Living Adjustment
Effective January 2026, SSA increased all Social Security and SSI benefits by 2.8%. This is a modest increase compared to the record 8.7% in 2023, but a step up from 2025's 2.5%. For the average beneficiary, it adds about $56 per month.
How SSA Calculates the COLA
The COLA isn't a political decision — it's a formula. SSA compares the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) for July, August, and September of each year against the same period of the prior year. If the average rises, benefits rise by the same percentage in January.
The 2026 COLA of 2.8% reflects CPI-W data from Q3 2025 vs. Q3 2024. SSA announces the following year's COLA every October. It's applied automatically — you don't need to apply or request the increase.
CPI-W vs. what seniors actually spend. The CPI-W tracks spending patterns of working-age adults — not retirees. Seniors spend more of their income on healthcare and housing, which typically inflate faster than the CPI-W captures. Critics argue a senior-specific index (CPI-E) would produce higher COLAs more of the time.

Will the COLA Be Offset by Medicare?
Yes — partly. In 2026, the standard Medicare Part B premium is $202.90/month, up from $185.00 in 2025. The Social Security "hold harmless" rule protects most beneficiaries from having their net SS check reduced by Part B increases, but the premium hike does eat into the COLA gain.
Net impact example — average beneficiary: 2026 COLA adds +$56/month. Part B premium increase subtracts -$17.90/month. Net check increase: approximately +$38.10/month for most beneficiaries.
