There have been a lot of numbers shown about in a rather loose fashion for what health insurance costs so I'll put my actual costs on the table. This is for a family plan (in my case this is my wife and myself but the group rate would cover any number of children.
Prior to 2009 I was on an HMO, cadillac plan, with no deductible, 10/25/50 copays for Rx, 30 for office visits, 200/day hospital, 50/ER visits, $2000/yr out of pocket cap. The total premium for this plan for 2009 is $13666.90/yr with my company picking up ~67% of the premium.
I tracked all our expenses, asked providers what things actually cost, and based on these costs and our history, I switched to a "consumer-driven" high deductible plan this year. This is a donut plan where the first $2500 of any medical expenses are 100% covered, the next $1500 is entirely out of pocket, then a traditional 80/20 plan kicks in but also includes a 10/25/50 copay for Rx. $4000/yr out of pocket cap in network, $6000/yr cap out of network for out of pocket costs. The total premium was $9682.66/yr with my employer picking up ~75% of the premium.
For this year we saved ~$1200 in premiums by switching to the high deductible plan. If our expenses had stayed in line with past years, we would have ended up saving ~$1200 overall, which is why we switched.
We use an FSA to pay the out of pocket costs (copays/coinsurance) on a pretax basis and plan that out based on past expenses.
A benefit to the consumer driven plan is that we do see all the bills and see what providers charge. We also see the insurance company's negotiated rates which are much lower than what the providers bill, so much lower that one realizes that those billing rates are total bullshit.
Now to the point. This wasn't a normal year. We did have much higher expenses than in years past (two trips to the ER via ambulance and one overnight hospital stay) that blew out our projections. Months after these events, the bills for this are still coming in (due to grossly inefficient, private hospital billing procedures) so we still don't have a clear picture of what the care cost us. Note: consumers can not make reasoned decisions about level of care desired when providers simply will not provide cost information at the time of service. Based on the bills received so far we estimate that we will hit the out of pocket limit for the year and likely already have done so. Until the final bills come in, I can't say whether or not the switch to a high deductible plan has paid off financially but I do know the risk premium should not be considered trivial when selecting a plan.
Edit: I should add that even though we have a chronic condition in the family requiring four daily maintenance meds and no foreseeable cure, even with these med costs and even with the ER visits mentioned above, the insurance company will still make money off us this year as they have every year.
