The US could insure 30 million more Americans and virtually eliminate out-of-pocket health care expenses while saving $2 trillion in the process, according to a new report about Medicare for All released by the libertarian Mercatus Center.

In the report, Charles Blahous attempts to roughly score Bernie Sanders’s most recent Medicare-for-All bill and reaches the somewhat surprising (for Mercatus) conclusion that, if the bill were enacted, the new costs it creates would be more than offset by the new savings it generates through administrative efficiencies and reductions in unit prices.

The report’s methods are pretty straightforward. Blahous starts with current projections about how much the country will spend on health care between 2022 and 2031. From there, he adds the costs associated with higher utilization of medical services and then subtracts the savings from lower administrative costs, lower reimbursements for medical services, and lower drug prices. After this bit of arithmetic, Blahous finds that health expenditures would be lower for every year during the first decade of implementation. The net change across the whole ten-year period is a savings of $2.054 trillion.
