Record-high inflation could mean a bigger Social Security cost-of-living adjustment in 2023

Social Security beneficiaries started 2022 with a 5.9% cost-of-living adjustment to their monthly checks, the highest increase in about 40 years.

But as inflation climbs with each month, the buying power of those benefit increases has diminished.

The Consumer Price Index for all Urban Consumers, or CPI-U, rose 8.5% from a year ago, according to March data released by the U.S. Bureau of Labor Statistics on Tuesday.
