The Social Security cost-of-living adjustment (COLA) is the annual percentage increase applied to retirement, Social Security Disability (SSDI), and Supplemental Security Income (SSI) benefits to keep them aligned with consumer prices. SSA announces the new COLA every October, based on the change in the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) between the third quarter of the current year and the third quarter of the previous year. Benefits adjusted by the new COLA appear in January checks.
The 2026 COLA is 2.5%. This page lists every Social Security COLA since 2000 and notes the years that stand out: the record 8.7% increase for 2023, the three years with no adjustment at all (2010, 2011, and 2016), and the run of small adjustments in the 2014 to 2017 period.

What COLA means for your Social Security benefit
A COLA is applied to your whole benefit amount, not just the "base" portion, so if you receive $2,000 a month and the COLA is 2.5%, your new check is $2,050. That adjustment is permanent. It is baked into the calculation for every future year and is included in any new COLAs on top of it. This is why delaying Social Security past your full retirement age is a powerful inflation hedge: each year of delayed retirement credits is calculated before any COLA, and then future COLAs stack on top of the larger number.
COLA also applies to SSI, the Social Security maximum family benefit, and the earnings test limits. It does not automatically update the taxable wage base, that is calculated separately based on national average wage growth, or the federal income tax thresholds that govern when benefits become taxable.
Social Security years with no COLA
Three years in this table had a 0.0% adjustment. Those were years in which CPI-W did not rise on a year-over-year basis, so no increase was paid. The most recent case was 2016, when a drop in gasoline prices pulled the CPI-W index below the previous year's reading. By law, Social Security benefits cannot decrease as a result of negative CPI-W, so SSA skips the COLA for that year instead.
How COLA affects long-term Social Security planning
Over a 30-year retirement, COLAs compound in a way that is easy to underestimate. A benefit of $2,000 in 2025, if COLAs averaged 2.5% a year, would be worth roughly $4,200 a month in nominal dollars by 2055. That is not an increase in purchasing power, it is just protection against prices rising over time. But it is far more inflation protection than most private pension plans offer.
