the best is to call a local insurance agent for enrollment 

Ur from ohio ? +Edward Harris 

valid point. I believe it goes something like this:
1.  138% of poverty - 500 ded 1500 Max Out of Pocket and 93/7 coinsurance.
2. 138-150% of poverty  - 1500 ded- 87/13 Cost sharing

+Burdel Blunt Oh I'm sorry, I thought you were asking about how much of your medical bills you could expect to pay when buying an individual plan.

Remember! Out of pocket cost sharing makes a big difference, it's nice to have a plan that pays out even before you hit the deductible. 

What was the point that I missed?

Go Josh and many others like me. Thank you +HealthCare.gov​. 

Obamacare 

make sure your doctor are on the network

+Clint White the 315 millions you are alluding to, most of these people Already had insurance through their employers or bought policies on their own. The idea of ACA is to close the gap between uninsured and insured. You see, all the uninsured were stressing the system that used to be in place. They would just show up to the emergency and get treatments they couldn't afford to pay, then the weight of the loss money was getting put on insured people to cover the deficit, which is not fair. So ACA came along, to allow uninsured people to buy insurance and be responsible so that we all contribute to lower the cost of medical bills. Now the way it is right, it is very expensive. That's why the government recognizes that not everyone can afford it, unless there are tax credits for certain household income threshold. So let's be responsible Americans. Do your part and no one would be paying for someone else medical bills. The is fairer that way.

For many broker websites (and the government website), rates have just been released. In many states, UnitedHealthcare and Aetna are now offering Exchange plans. The deadline for a Jan 1 effective date is December 15th, so don't forget that date!
