I know somebody who works for BCBS and she has confirmed their premiums are going up because of Obamacare. And that makes sense, right?
The real answer is "it depends". Everyone's rates will go up because they always go up. The question is, how much will they go up compared to what they would have gone up anyway?
In general, if you're young &/or healthy, then higher than average. If you're old &/or sick, lower than average. Young males & old females will be higher while young females & old males will be lower (again, this is all *in general*).
If you had a pre-existing condition, then an extreme amount lower (although, I guess technically, if you didn't have a premium before, that means way higher than $0, but the point is you can get insurance now).
If you work for a small company (<51 employees) or are on individual coverage, you'll see bigger swings than if you work for a particularly large company (250+), which will be virtually unaffected by most of the regulations. The reason is that the insurance companies will no longer be able to take your claims into account. So, small groups or individuals that would have gotten lower increases will be higher than normal & those that would have gotten higher increases will be lower than normal as everyone gets an increase closer to the average.
If you're on Medicare or Medicare Advantage, you'll be pretty much unaffected (again, just compared to what you would have gotten if Obamacare didn't exist).
There will be some added fees for Obamacare, to help with subsidies. Your rate could go up in the 1-2% (EDIT: & probably a little higher when you renew in 2014 compared to your 2013 renewal) range just due to those fees. On the other hand, at your next renewal, adding millions of previously uninsured people to the risk pool should drive down average claims, which should mean lower premiums for everyone. Also, the insured won't be picking up the tab for the uninsured who go to the emergency room, & that will definitely drive down costs.
Also, just as a point of clarification for some people that need it (not you, Berzerker), there is no product called Obamacare. No one can "buy Obamacare". It's a set of regulations that apply to private companies. There is no "government plan" or Public Option. The government employees have insurance through private companies just like anyone else.
The only government plans are Medicare & Medicaid, & they already existed.
