Did the Affordable Care Act Make Health Care More Affordable?

The expiration of the ACA’s enhanced premium tax credits at the start of 2026, combined with rising insurer premiums, put a spotlight on health care affordability that extends beyond Marketplace enrollees. KFF’s Cynthia Cox examines the ACA’s record and the broader underlying question it raises: what’s a fair price for Americans people to pay for health care?

The ACA MarketplaceS

In Preliminary Rate Filings, ACA Marketplace Insurers Largely Propose Double-Digit Premium Increase For 2027, Following a Steep Climb This Year 

ACA Marketplace insurers are proposing a median premium increase of 14% for 2027— indicating a likely second consecutive year of double-digit increases, according to a new analysis of preliminary rate filings in 16 states and DC. If these increases hold, typical premiums for insurers participating in the ACA Marketplaces would jump by more than one-third between 2025 and 2027.

The Average Marketplace Deductible Grew by About $1,000 Per Person in 2026, With More Enrollees Shifting to Higher-Deductible Plans as Enhanced Tax Credits Expired

The average Affordable Care Act (ACA) Marketplace deductible experienced the steepest increase in history—growing by 37% or over $1,000, from $2,759 in 2025 to $3,786 in 2026 as enhanced premium tax credits expired, according to a new KFF analysis. After the enhanced tax credits ended, many Marketplace shoppers shifted toward lower-premium, higher-deductible plans.

  • What’s Driving the GOP Health Plan

    From Drew Altman

    This was published as a Wall Street Journal Think Tank column on May 30, 2014. Conservative House Republicans are pushing for a vote on a GOP health-care plan, presumably to appeal to their base, to give GOP candidates health reform ideas to talk about on the campaign trail and to show that they have a policy position beyond repealing the Affordable Care Act. Polling shows they have a ways to go. The Kaiser Family Foundation’s May tracking poll…

  • The Affordable Care Act and Insurance Coverage in Rural Areas

    Issue Brief

    Rural populations face disparities compared to metropolitan populations in health care. While rural individuals were not more likely to be uninsured than metropolitan counterparts pre-Affordable Care Act, they were poorer and less likely to have private insurance. With coverage changes in the ACA involving an expansion of Medicaid for poor and near-poor populations, decisions by states with large rural populations may cause rural residents to have disparate access to coverage, which may exacerbate cost and…
