That is what your employer paid for your insurance. You might be able to get a cheaper plan on Obamacare/ACA. Companies pay large portion of your insurance that you never see. COBRA brings it all to light.

There is a movement to count medical benefits as income, which would shed light on this (in fact that was part of Obamacare/ACA, but politicians keep putting it off because they know no wants to pay taxes on their healthcare...)

Yeah, I would be more fine with employer provided healthcare if people had to pay taxes on it.

I work at a small company and around the ACA times they told us they were weighing their options: removing healthcare benefits with a corresponding bump in pay (including tax ramifications), or keeping healthcare. At the time they let us know what they were paying, and it was a shitload - something like $18k/year for my family of 3.

They ended up keeping healthcare. And now I have a family of 5. No clue what they pay, but I'm sure it's a ton.
