I'll tell you because of the medical policy changes where I work (I telecommute and live outside the new policies 'covered area') I'm no longer covered by my company's medical care, so I had to go out an look both at the ACA exchanges for my state (NY) or look at full up "private" policies
The ACA plans all sucked, because NONE would cover my 16YO son "He has to go on Medicare"
So, I bought what is considered a Platinum level plan - (4 people, Me, My wife, my 20 YO daughter at college and said 16YO son). Cost? About $2400/month (does not include dental or vision - the company still provides that)
Some of the fun?
I can't use a flex spending account! That's right, the law now prevents you from using a FSA to pay for Gold or Platinum level plans, so this money is all AFTER taxes! (The company does reimburse me for what they used to kick in for my plan when they covered me - less than half)
The best plan I found has a fairly large "co-insurance" (you pay your deductible, AND your co-insurance)
I know what it costs - all TOO well, and have told my MDs "This is out of pocket". One interesting thing - You will find most MDs have a different, lower rate for services "Out of Pocket" (there was some time while the new plan was kicking in I had nothing, even though it became retroactive). Comes from them not having to do all the paperwork!! (plus the insurance companies only pay a percentage of your MDs bill. The bill might say $200, but they have a negotiated rate with your insurance co to take only $80)
