The number of people who are uninsured would increase by 17 million in 2018, compared with the number under current law. That number would increase to 27 million in 2020, after the elimination of the ACA’s expansion of eligibility for Medicaid and the elimination of subsidies for insurance purchased through the marketplaces established by the ACA, and then to 32 million in 2026.

Average premiums in the nongroup market (for individual policies purchased through the marketplaces or directly from insurers) would increase by roughly 25 percent—relative to projections under current law—in 2018. The increase would reach about 50 percent in 2020, and premiums would about double by 2026.
