Social Security benefits will increase 2.8 percent in 2019, the largest cost-of-living adjustment (COLA) in seven years.

The COLA, announced Thursday, Oct. 11, will increase the average Social Security retirement benefit by $39 a month or roughly $468 a year. The average single retired Social Security recipient is expected to receive $1,422 in December 2018 before increasing to $1,461 a month later. The COLA affects household budgets for about 1 in 5 Americans, including Social Security beneficiaries, disabled veterans and federal retirees.
