"On average, people will have a choice of 56 different insurance plans -- depending on which state you live in, though, that figure could range from seven (in Alabama) to 106 (in Arizona). The average number of insurers in a state is eight, though that again ranges from one to 13 in different states.
As for premiums, before tax credits kick in, they will average 16 percent below the Congressional Budget Office's original estimates for a silver-level plan (which covers 70 percent of costs). The number of insurers in a state is directly tied to how low premiums will be, Lambrew noted. Arizona, with an average of 106 plans to choose from, had the second-lowest average premiums for a 27-year-old adult: $166 a month. Wyoming, with an average of 16 plans, had the highest average premium at $342 a month.
But then the tax credits take effect. Those knock the premium for that 27-year-old, projected to earn $25,000, down to $145 in most states."
