Freedom Partners Chamber of Commerce has analyzed all publicly available information for health-insurance premiums from healthcare.gov and state insurance departments. It then calculated the weighted averages for all health-insurance plans available on the Affordable Care Act’s exchanges. The weighted average gives a more accurate view of overall premium increases, because it takes into account each insurance plan’s market share.

Findings reveal that nationally, premiums for individual health plans increased on average between 2015 and 2016 by 14.9%. Consumers in every state except Mississippi faced increased premiums, and in no fewer than 29 states the average increases were in the double digits. For a third of states, the average premiums rose 20% or more.
