The $1 trillion in new revenue would come from the law's expansion of Medicaid and from subsidies to individuals purchasing insurance.
Though most of the money would eventually flow to healthcare providers, insurers would keep an average of $22 billion per year for profit and administrative costs, the study said.
The Supreme Court is expected to issue its decision on healthcare reform before the end of June. If upheld, the law is projected to expand insurance coverage to 32 million people by 2016.
The study estimated that through 2020, the Medicaid expansion will cost $669 billion, and the private insurance subsidies $557 billion. The two represent about 98 percent of the law's total costs, it said.
