$1000 a month would be cheap.
My share of premiums for my family plan is $20k/year. My employer is a non-profit and very transparent about expenses. They pay an additional $30k.
That's before deductible. Also not counting Medicare tax.
That means 50k/yr. I'm fairly well paid. That's nearly a fifth of my total compensation package, and almost than the median adult income in my town. Just in premiums.
