Every year, Social Security is eligible for a COLA. When inflation remains flat, Social Security benefits remain flat. When there's a decrease in inflation from one year to the next, Social Security benefits also remain flat.

American seniors are frustrated with how Social Security adjusts for inflation, and they want change.

Social Security's cost-of-living adjustment could rise 2.7%. But Medicare Part B premiums are set to rise even more, eating most of the COLA.
