I tried to buy a plan on healthcare.gov in January of 2015.
I elected for a Bronze plan which would have paid 60% and I would have paid 40%.
For my family of four (two adults and two minor children) with basically no health issues the cost of the plan would have been approximately $12,000, or $1,000 per month.
My employer at the time offered health insurance which I had, but I had a job offer which paid approximately $20,000 more per year after taxes as a 1099 contractor, and I would have to buy my own insurance.
Ultimately I did not take the contract job because of the cost of the plan.
Oh, and for 2016, the company I stayed with where I had insurance - my plan was canceled by United because it was no longer cost effective - United cited increased costs due to new Federal regulations in a letter I have from them, addressed to me. My insurance approximately doubled in cost from $2,600/year to $4,900/year for LESS coverage with my new lower plan.
