Kurt Giesa and Chris Carlson, members of the American Academy of Actuaries, provided one set of estimates in January 2013. Writing in the Academy’s journal, Contingencies, these actuaries from Oliver Wyman in Milwaukee predicted that under the ACA, premiums for young, healthy adults age 21 to 29 would increase two to four times as much as premiums if they bought similar insurance before ObamaCare.

For singles between 21 to 29 who are ineligible for government subsidies because of their income, the actuaries forecast that premiums would be 42% higher than without ObamaCare. For those age 30 to 39 with similar coverage and circumstances, premiums would be 31% higher than without ObamaCare. By comparison, those age 60 to 64 with single coverage and ineligible for subsidies would see about a 1% increase in premiums over what they would be paying absent ObamaCare.

Young people don’t need to make much to pay more than they would without ObamaCare. The study’s “core finding” was that single young adults 21 to 29 with incomes of as little as $25,000 “can expect to see higher premiums than would be the case absent the ACA.” That’s after accounting for ObamaCare subsidies.
