In May, the average Social Security check for retired-worker beneficiaries was $1,916.63, equating to roughly $23,000 on an annualized basis. This income helps form a financial foundation for most seniors, with 88% of respondents in a Gallup survey indicating that their Social Security payout represents either a "major" or a "minor" source of income.

The purpose of Social Security's COLA (Cost-of-Living Adjustment) is to ensure that the purchasing power of benefits is not eroded by inflation5. It accounts for price changes in a broad basket of goods and services, allowing beneficiaries' income to reflect inflation or deflation over time.
