The problem is that in the US it's a fixed amount vs in Germany a proportion of your income. This works OK for higher incomes but for lower incomes it's a big problem. And as always, the people in the middle get screwed. Not enough money to afford the premiums easily but too much money to get subsidies.
SO this is just what the employer pays. The employee then pays premiums monthly as well for access. Employers pay somewhere between $5k and $25k (or more) per employee a year for health care depending on quality and portion of premiums they pay for the employee. Usually its split, so someone makes $80k a year, they pay $10k a year in premiums, employer pays $10k a year in premiums.
In Europe (here: Germany example), which is frequently seen here as the ideal example of healthcare spending:
Employees and employers typically split around 14.6% of gross salary for public health insurance. [1]
