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.

  • Betting on Private Insurers

    Perspective

    Just-released estimates of national health spending in 2010 by the Centers for Medicare and Medicaid Services (CMS) show that 45% of our health care spending is financed by the federal and state governments, primarily through the Medicare and Medicaid programs. This share has grown temporarily in recent years because of the economic downturn, as private insurance has declined and Medicaid has grown. It has also increased due to our demographic destiny: the growing cohort of baby…

  • August Kaiser Health Tracking Poll: A Look At The GOP As The Republican Convention Draws Near

    Perspective

    Despite the ongoing focus on Republican opposition to the Affordable Care Act (ACA), the latest Kaiser Health Tracking Poll finds that the ACA is not the top health care priority among Republicans. While jobs are still the number one issue, when asked about the health care issues that will impact their vote this fall, Republicans’ top concern was the cost of health care and insurance, named by two-thirds as either “extremely” or “very important” to…

  • Transparency and Complexity

    Perspective

    This fall a new rule takes effect requiring all private health plans to offer a uniform, simple to read, summary of benefits and coverage (SBC).  The SBC will provide consumers with standardized information about how plans cover essential health benefits and what coverage limits and cost sharing applies. The SBC is one of the most popular provisions of the ACA.  Consumers often find health insurance difficult to understand and would no doubt welcome a plainly written…

  • KFF Data Note: Americans’ Views on the Personal Impact of the ACA and the Supreme Court’s Decision

    Perspective

    As the Supreme Court hears cases challenging the constitutionality of parts of the Affordable Care Act, a relatively small share of the public thinks the Supreme Court’s decision will have a lot of impact on their family (28 percent). At the same time, the public is divided as to whether the law overall will leave their own families better off (26 percent), worse off (33 percent), or if it won’t make much difference (34 percent).…

  • KFF Data Note: A Snapshot of Public Opinion on the Individual Mandate

    Perspective

    This week, the Supreme Court hears arguments on several challenges to the Patient Protection and Affordable Care Act (ACA), including the provision that requires individuals to purchase health insurance as of 2014, known as the individual mandate. For the two years since the law’s passage, and during the debate leading up to it, this provision has been one of the most controversial aspects of the law. As the lawyers, policymakers, ACA opponents and supporters focus…

  • Public Opinion on the ACA: Cruising or Turbulent Ride?

    Perspective

    Regular readers of the Kaiser Health Tracking poll know by now that public opinion on the Affordable Care Act (ACA) has been at a steady cruising altitude since it was signed into law on March 23, 2010, with a little over four in ten viewing the law favorably and a similar share unfavorably. But, has public opinion on the law since passage been more turbulent for different groups of Americans, for example, those with lower…

  • Is a Death Spiral Inevitable If There is No Mandate?

    Perspective

    If the Supreme Court acts within the next couple of weeks to overturn the individual mandate in the Affordable Care Act (ACA) while leaving the rest of the law intact, expect to hear a lot about how the individual insurance market will be destined for a "death spiral." When compared with implementing the ACA in full as planned, there's a consensus that eliminating the mandate would increase premiums and mean that far fewer of the…

  • How the ACA Changes Pathways to Insurance Coverage for People with HIV

    Perspective

    There are multiple sources of insurance coverage and care for people with HIV in the United States.  These include public programs, such as Medicaid and Medicare, and the Ryan White HIV/AIDS program, as well as private coverage through an employer or in the individual market. Medicaid, the nation's principal safety-net health insurance program for low-income Americans, is estimated to cover the largest share of people with HIV. Fewer are covered by Medicare, the federal health…

  • How Small Business Owners Get Health Insurance

    Perspective

    As with any economic policy issue, there has been much discussion of how the Affordable Care Act (ACA) will affect small businesses. But, there’s been very little focus on how the health reform law will affect the owners of those businesses as people. As our recently released Employer Health Benefits Survey shows, small businesses are much less likely than larger businesses to offer health benefits to their workers. Half of businesses with 3-9 workers and…

  • Data Note: Americans’ Views on the Personal Impact of the ACA and the Supreme Court’s Decision

    Poll Finding

    This Data Note draws from the March 2012 Kaiser Health Tracking Poll and examines people's impressions of how the law and the Court case will affect them, focusing primarily on those groups that are in the position to receive the greatest benefits. For the most part, those that stand to benefit most are not more likely than others to expect to be better off under the law, or to feel that the Supreme Court's decision…
