Estimated insurance coverage costs revised downward.
Relative to their previous projections, CBO and JCT now estimate that the ACA’s coverage provisions will result in lower net costs to the federal government: The agencies now project a net cost of $36 billion for 2014, $5 billion less than the previous projection for the year; and
$1,383 billion for the 2015–2024 period, $104 billion less than the previous projection.
The estimated net costs for 2014 stem almost entirely from spending for subsidies that are to be provided through insurance exchanges (often called marketplaces) and from an increase in spending for Medicaid…
Those estimates address only the insurance coverage provisions of the ACA, which do not generate all of the act’s budgetary effects. Many other provisions, on net, are expected to reduce budget deficits. Considering all of the provisions—including the coverage provisions—CBO and JCT estimated in July 2012 (their most recent comprehensive estimate) that the ACA’s overall effect would be to reduce federal deficits.
Note that the overall budgetary effect of the ACA is to reduce federal deficits. As indicated in CBO’s 2012 estimate, repeal of the ACA would have resulted in a ten year increase in budget deficits of over $100 billion.
