I started with Obamacare here in Massachusetts in 2015. It was about $300/month. It went up closer to $400/month for 2016. I just got the first bill for the same plan (Harvard Pilgrim Standard Silver) but at 2017 rates: $705.05/month.
This is for a plan where I pay for at least the first $2000 per year. So if I do actually need health care for any reason the annual cost will be at least $10,460. All of this must be paid with post-tax dollars since I’m paying for it rather than having an employer pay for it.
Note that if I were getting the federal minimum wage of $7.25 per hour and working full time (2000 hours/year), assuming an income and payroll tax rate of 0 percent, I would generate a surplus of only $4,040 with which to pay for (a) food, (b) shelter, (c) retirement, (d) taxes to feed the Great Father in Washington, (e) taxes to support local schools and state operations, etc.
Exercise for the reader: What is the implied annual inflation rate here and what will the cost be next year?
