United Benefit Advisors has produced this chart showing group health insurance costs by state.
It should come as no surprise that the Northeastern US is the most expensive area of the country for group health insurance. However, the amount of difference in cost might be a shock.
These are 2016 figures. The numbers for 2017 are a little higher, and we expect the numbers for 2018 to increase by more than 15%. These are costs under group heath insurance policies. The cost for individual policies will be slightly higher (before the ACA subsidy is applied).
