California's single-payer pricetag: $400 billion

A bill transforming California’s healthcare system into a single-payer model would cost $400 billion, a sum that widely surpasses the state’s $125 billion budget.

According to a legislative analysis, the state could seek various waivers to help pay for the program through Obamacare provisions and Medicaid, but to fully fund the system lawmakers would need to add a 15 percent payroll tax. The cost would largely be offset by current state, federal and private spending on healthcare in California, but total costs would still increase by roughly $50 billion to $100 billion a year.
