Cost-of-living adjustments (COLAs) raise Social Security benefits most years. Here is how the 2026 COLA works and why it matters for claiming.

Social Security benefits are adjusted each January for inflation using the Consumer Price Index for Urban Wage Earners (CPI-W). The 2026 COLA was 2.8% — a $2,000 benefit became about $2,056.

COLAs matter for claiming in two ways: they apply even before you claim (so delaying lets the COLA-adjusted amount grow), and they compound over a long retirement — a 3% average COLA roughly doubles nominal benefits over 25 years. That is why the COLA calculator is worth running alongside break-even math.

COLAs are not guaranteed — in low-inflation years (2010, 2011, 2016) there was no COLA.
