As leaders in Congress kick off the 115th session by assuring the public they will repeal the Affordable Care Act (ACA) in full by the end of this year, a newly released estimate puts the cost of a total repeal at roughly $350 billion through 2027.

According to the nonpartisan Committee for a Responsible Federal Budget, repealing the law's Medicare-related cuts and its tax increases -- such as the "Cadillac tax" on high-cost insurance plans -- could cost the government more than if it left the ACA in place.

But the report found that lawmakers could save money if they just repeal parts of the law. For example, if Congress only does away with the ACA's coverage provisions (mainly the Medicaid expansion), it could save $1.55 trillion through 2027.
