Just days away from its launch, the Department of Health and Human Services has finally released premium rates for the 36 state Obamacare exchanges it will run. One analysis found many consumers are in for higher costs.

HHS proudly announced that the final premiums it’s decided on are lower than the Congressional Budget Office (CBO) had originally predicted. But though the prices are lower than the CBO had thought, both of those numbers are dramatically higher than what Americans currently pay.

The conservative Manhattan Institute for Public Policy Research compared HHS’s numbers to current insurance premium averages and found that Obamacare will almost double underlying insurance rates for the average 27-year-old man, Avik Roy reported in Forbes.
