Social Security recipients will receive an annual cost-of-living adjustment of 8.7% next year, the largest increase since 1981, the Social Security Administration announced Thursday.

The spike will boost retirees’ monthly payments by $146 to an estimated average of $1,827 for 2023.

The hefty increase, which follows a 5.9% adjustment for this year, is aimed at helping Social Security’s roughly 70 million recipients contend with the high inflation that’s been plaguing the US since last year.

“Will the COLA be enough to keep up with inflation? It’s too early to say,” said Mary Johnson, Social Security and Medicare policy analyst at The Senior Citizens League, an advocacy group. “It depends on what inflation is going to do from October onwards.”

The adjustment is the highest that most current beneficiaries have ever seen, but that’s because it is based on an inflation metric from August through October, which is also around 40-year highs.

A related metric, the Consumer Price Index, increased 8.2% in September, compared with a year ago, the Bureau of Labor Statistics announced Thursday.
