Adam Beck, a professor of health insurance at the American College of Financial Services, was quoted in the CheatSheet report saying that "[t]he premiums are actually right where the Congressional Budget Office originally predicted they'd be in 2017."

Also, the U.S. Department of Health and Human Services pointed out that several of the states facing large premium increases actually had marketplace premiums considerably below the national average and "especially far below the cost of comparable employer plans in that state."

Lucky Indiana and Massachusetts consumers will find that the average ACA premiums will fall by 3 percent. New Hampshire, Arkansas and Ohio are also lucky enough to see premiums fall, albeit by a scant 2 percent.

Before you despair over what exchange coverage may cost you, you might be heartened by the Department of Health and Human Services, which said that 22 percent of those who aren't already getting subsidies to help them pay for their health insurance could be eligible for tax credits in 2017. And it reminded consumers that they could always switch to a lower-cost plan — although of course that's not likely to be consumers' first choice, because of the necessity of switching doctors.

Beck added that while "[m]ost marketplace consumers will still pay less than $100 per month," for the "17 percent who don't receive subsidies, these increases are really, really tough."

CheatSheet evaluated the premium increases across the country and came up with this list of the 10 hardest-hit states. With luck, you don't live in any of them — or else you get health coverage from an employer.

Whether the Cubs win the World Series or not, the news isn't good for exchange shoppers in Illinois.

And their average tax credit per month is less than that in Kansas, at just $156.

Nebraskans will not be happy in 2017 if they're not eligible for subsidies. While 2016's average premium was $272, in 2017 they'll be paying an average premium of $411. Not only is it a big chunk of change, it's a 51 percent increase. Those who do qualify for the average tax credit, though, will be able to take advantage of an extra $296 per month.

2. Oklahoma

Oklahoma probably won't feel all that "OK" to folks who are buying their health coverage on the exchanges next year. After this year's average premium of $251, a 69 percent increase will boost the average 2017 premium to $424 — an increase of 69 percent. The one consolation is a decent average tax credit per month of $282.

1. Arizona

Pity the poor Grand Canyon State. At least some residents will feel as if they have a Grand Canyon in their checkbooks when they find out that 2016's average premium of $196 is giving way to 2017's $422 — an increase of 116 percent. The average tax credit will help at least some folks, though, at $280 per month.
