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 2017 is 2.0 percent and is first payable in January 2018.

The table below provides estimated average benefits for certain beneficiary types, at the end of December 2017.
