Average Affordable Care Act benchmark premiums have increased 3.4% for the 2023 coverage year according to a new analysis from the Robert Wood Johnson Foundation. 

It also found that premiums are greatly affected by the number of insurers competing in the rating region: The more insurers, the lower the benchmark premiums, and vice versa. For example, a region with one or two insurers had premiums that averaged $128 and $119 higher than regions with five or more insurers.
