New beneficiaries coming onto Social Security's rolls tend to have, on average, higher
benefits than those leaving, so average benefits normally rise from month to month. This gradual
rise in average benefits is altered by abrupt increases due to annual cost-of-living
adjustments or COLAs. The COLA for December 2024 is 2.5 percent and is first payable in January 2025.
The table below provides estimated average benefits for certain
beneficiary types, at the end of December 2024.
