NOW AVAILABLE: prices for every insurance plan offered on Healthcare.gov. Download it now before it goes away.

I've just had time for a brief glimpse, but my best guess is a 15% decrease to a 20% increase for individual plans that (from the data available) clearly appear to be inferior to my wife's current employer-sponsored PPO plan. There are only 4 such plans to choose from, all from the same insurer. All the remaining plans are HMO plans.

NOTE: the percent rate changes I've quoted above assume the employer contribution; if the rate change were based solely on employee contributions, the rate increase would be on the order of 115%-200%.
