The average deductible for Affordable Care Act marketplace plans increased sharply in 2026, according to a new KFF analysis. Rising healthcare costs and the expiration of enhanced premium tax credits pushed many Americans toward cheaper plans with higher out-of-pocket expenses. As a result, average ACA deductibles climbed by 37%, marking the steepest increase in the program’s history.
The report highlights growing affordability concerns across the healthcare industry. Many consumers now face difficult decisions between paying higher premiums or accepting plans with costly deductibles. Consequently, healthcare experts warn that millions of Americans may delay treatment or reduce healthcare spending because of rising financial pressure.
Why ACA Deductibles Increased in 2026
The primary reason behind the deductible spike was the expiration of enhanced federal premium tax credits. These subsidies had helped millions of Americans lower their monthly healthcare costs during previous years. However, after those benefits ended, insurance premiums rose significantly across ACA marketplaces.
To reduce monthly payments, many consumers switched from silver plans to bronze plans. Bronze plans usually offer lower monthly premiums but come with much higher deductibles and out-of-pocket costs. According to KFF, the average ACA deductible increased from $2,759 in 2025 to $3,786 in 2026.
Additionally, bronze plan deductibles averaged nearly $7,500 in 2026. This dramatic increase created financial stress for many middle-income families who rely on marketplace coverage. Experts believe the trend reflects a growing affordability crisis in the individual insurance market.
Impact on Marketplace Enrollment
Higher healthcare costs also affected ACA enrollment numbers. KFF estimates that marketplace enrollment could decline to approximately 17.5 million people in 2026. In 2025, enrollment reached more than 22 million individuals. Therefore, millions may lose or drop coverage because they can no longer afford rising premiums and deductibles.
Furthermore, enrollment declines were especially severe among people earning slightly above the federal subsidy threshold. These individuals lost access to expanded financial assistance and faced steep premium increases. As a result, many consumers either downgraded coverage or exited the marketplace completely.
Several states reported particularly large enrollment drops. North Carolina, Ohio, West Virginia, Indiana, Delaware, and Arizona experienced some of the biggest declines in ACA plan selections.
Premium Payments Continue Rising
Premium payments increased sharply in 2026. Average monthly payments rose from $113 to $178 per month, representing a 58% increase nationwide. While some consumers reduced costs by selecting bronze plans, many still struggled to manage rising healthcare expenses.
KFF also found that many consumers reduced spending on food, clothing, and household necessities to pay healthcare bills. These findings illustrate the growing burden of healthcare affordability in the United States.
Shift Toward Bronze Plans
Bronze plans became increasingly popular in 2026 because consumers searched for lower monthly premiums. Enrollment in bronze plans increased from 30% to 40% of total ACA marketplace selections. Meanwhile, silver plan enrollment fell to a record low.
Silver plans traditionally provide lower deductibles and cost-sharing reductions for lower-income individuals. However, without enhanced subsidies, many consumers could no longer afford them. Consequently, the market shifted heavily toward high-deductible coverage options.
Healthcare analysts warn that this trend may reduce access to preventive care and essential medical services. Patients with large deductibles often postpone doctor visits or avoid filling prescriptions because of financial concerns.
Cost-Sharing Reduction Enrollment Declines
The percentage of consumers selecting cost-sharing reduction silver plans dropped to only 37% in 2026. This represents the lowest level recorded since ACA marketplaces launched.
Many eligible consumers chose cheaper plans despite losing valuable deductible assistance. Therefore, healthcare advocates worry that underinsured Americans may face greater medical debt and worsening health outcomes in the coming years.
Rising Financial Pressure on Consumers
Healthcare affordability continues to challenge families nationwide. According to KFF surveys, many marketplace enrollees reported serious financial strain after subsidy expiration. Some individuals reduced essential household spending to maintain insurance coverage. Others dropped insurance entirely because costs became unmanageable.
In addition, older adults experienced some of the largest premium increases. Many consumers between ages 55 and 64 reported dramatic cost hikes compared to previous years. This age group often faces higher healthcare needs, making affordability even more critical.
What This Means for Healthcare Access
Higher deductibles can discourage people from seeking medical care early. When patients delay treatment, health conditions often worsen over time. Consequently, hospitals and healthcare systems may eventually face higher costs from preventable illnesses and emergency care utilization.
Healthcare policy experts also believe rising deductibles could widen disparities in healthcare access. Lower-income families and individuals with chronic conditions may face the greatest challenges under increasingly expensive marketplace plans.
Potential Long-Term Consequences
If affordability problems continue, ACA enrollment may decline further in future years. Policymakers may face growing pressure to restore enhanced subsidies or introduce new financial assistance programs. Without policy intervention, healthcare costs could continue rising for millions of Americans.
Future Outlook for ACA Coverage
The ACA marketplace remains an essential coverage source for millions of Americans. However, affordability challenges threaten long-term enrollment stability. Industry analysts expect policymakers, insurers, and healthcare organizations to closely monitor enrollment trends throughout 2026.
At the same time, consumers may continue shifting toward lower-premium plans despite higher deductibles. Unless subsidies return or premiums stabilize, many Americans could remain underinsured. Healthcare experts stress that balancing affordability with adequate coverage will remain a major challenge for the healthcare industry moving forward.
Conclusion
The 37% increase in ACA deductibles represents a historic shift in healthcare affordability. Expiring subsidies, rising premiums, and increased enrollment in bronze plans contributed to record-high out-of-pocket costs in 2026. As consumers struggle with growing financial pressure, healthcare access and enrollment stability remain major concerns.
Moving forward, policymakers and insurers may need to explore new strategies to improve affordability and protect healthcare access for millions of Americans relying on ACA marketplace coverage.
