It varies depending on your age and where you live, and whether you're buying individual or family coverage. I'll give you an example, assuming you're asking about people who buy their own insurance and aren't eligible for any government assistance. I went to the Covered California web site https://coveredca.com/shopandcom... and found the price for a platinum plan for a 48-year-old person in a random zip code that turned out to be in San Bernardino County. I picked platinum because there's no deductible and low copay, I don't think there's any plan in the US where paying the premium entitles you to unlimited services with no copays. Not even Medicare is set up like that. The cheapest platinum plan is an HMO at $406 a month, or $4,872 a year. There's no deductible, but there are copays such as $20 for a primary care visit. There's no copay for preventive care services like mammograms.The maximum one would have to pay out-of-pocket in a year is $4,000. So, depending how much health care service you receive, it would cost anywhere from $4,872 to $8,872 a year.
