ACA Premiums Set to Rise 14% in 2027, Middle-Income Americans Hit Hardest as Subsidies Expire

Middle-income Americans straining to pay for Affordable Care Act health insurance are unlikely to get relief next year, according to a new analysis that shows insurers in the marketplace are proposing a second straight year of double-digit premium hikes.

Across the 77 insurers in the ACA program that have submitted rate filings that are publicly available, the median proposed premium increase for 2027 is 14%, according to Wednesday's analysis from the healthcare research nonprofit KFF. The insurers cited mounting healthcare costs, federal regulatory changes and the recent expiration of pandemic-era enhanced subsidies as the biggest factors driving premiums higher.

The rise in premiums adds to what already was a significant jump in 2026, when the median rate increase was 20%, according to KFF.

This comprehensive analysis examines the proposed rate increases, the impact on middle-income enrollees, the factors driving the hikes, and the broader implications for the U.S. healthcare system and the upcoming midterm elections.

The Subsidy Cliff: Middle-Income Americans Bear the Brunt

While most Americans in Obamacare still qualify for subsidies that protect them from paying the full premiums, middle-class enrollees who don't get those subsidies will face an especially stark increase in costs. That group includes households with incomes at or above 400% of the poverty level — about $63,000 per year for an individual or $129,000 for a family of four.

For these enrollees, the full burden of the 14% median premium increase will be felt directly. Unlike subsidized enrollees, whose out-of-pocket costs are capped based on income, middle-income Americans must pay the full premium amount. This creates a significant affordability challenge for families who earn too much to qualify for subsidies but not enough to comfortably absorb rising healthcare costs.

The subsidy cliff has become an increasingly contentious issue in healthcare policy debates. Advocates argue that the 400% threshold is arbitrary and leaves many middle-income families struggling with healthcare affordability. Some lawmakers have proposed extending subsidies to higher income levels or replacing the threshold with a more graduated phase-out.

The 2026-2027 Premium Surge: Two Years of Double-Digit Hikes

The current rate proposals continue a troubling trend. According to KFF, the median premium increase in 2026 was 20%, the largest single-year jump in the program's history. The 14% proposed increase for 2027 would mark two consecutive years of double-digit hikes, a pattern not seen since the early years of the ACA marketplace.

Year	Median Premium Increase	Key Factors
2026	20%	Post-pandemic cost catch-up, inflation, provider cost increases
2027 (Proposed)	14%	Subsidy expiration, sicker enrollee pool, rising hospital and drug costs

The rate increases come as federal lawmakers have proposed various policy changes to overhaul the expensive U.S. healthcare system, but no comprehensive legislation has amassed enough support to pass. The higher costs are contributing to Americans' existing worries about overall affordability, a concern that many voters say is front of mind with November's midterm elections looming.

Why Insurers Are Raising Rates: The Factors Behind the Hikes

Health insurers must send filings to regulators every year, explaining what they expect to see in premium rate changes for individual market health plans for the coming year. The KFF analysis of these filings identified several key drivers of the proposed increases:

1. Rising Healthcare Costs

The analysis found that insurers listed rising costs across the healthcare sector as the biggest cause of rising premiums. This includes:

Hospital costs: Continued increases in the cost of hospital care, driven by labor costs, supply chain pressures, and facility investments.
Prescription drug costs: Ongoing increases in the cost of brand-name and specialty drugs, particularly in areas like diabetes, cancer, and autoimmune conditions.
Workforce costs: Labor shortages and wage increases for healthcare workers, including nurses, physicians, and support staff.
Sicker patients: An increase in the severity of illness among enrollees, leading to higher medical claims.

Overall inflation contributed to this pressure, driving prices higher across the entire economy. Healthcare is a labor-intensive sector, and wage pressures have been particularly acute.

2. Expiration of Enhanced Subsidies

Insurers also blamed the expiration of federal subsidies that had offset costs for many people and caused the Affordable Care Act program to balloon in size in recent years. When those tax credits expired in January 2026, many plan costs skyrocketed.

That prompted large swaths of enrollees to depart the marketplace, leaving sicker patients who carry higher risks and costs, and driving premiums higher. This phenomenon, known as adverse selection, occurs when healthy individuals drop coverage, leaving a pool of enrollees with higher average healthcare needs.

3. Federal Regulatory Changes

Insurers also cited federal regulatory changes as a contributing factor. While the specific changes were not detailed in the KFF analysis, insurers have been navigating a shifting regulatory landscape under the current administration, including changes to subsidy rules and marketplace requirements.

Impact on Enrollees: Subsidized vs. Unsubsidized

The impact of the premium increases varies significantly depending on whether enrollees qualify for subsidies:

Enrollee Type	Income Level	Impact of 14% Increase
Subsidized	Below 400% FPL (<$63,000 individual)	Protected from full increase; out-of-pocket costs capped at percentage of income
Unsubsidized	At or above 400% FPL (≥$63,000 individual)	Faces full 14% increase; significant affordability strain

For subsidized enrollees, the tax credit structure ensures that premium increases are largely absorbed by the government. Enrollees pay a percentage of their income for the benchmark silver plan, with the government covering the remainder. This means that even as premiums rise, the out-of-pocket cost for subsidized enrollees increases only modestly.

However, for unsubsidized enrollees — the so-called "middle-income" group — there is no such protection. These enrollees must pay the full premium increase. For a family of four earning $130,000, a 14% increase could mean thousands of dollars in additional annual healthcare costs.

Political Implications: Midterm Elections and Healthcare Reform

The premium hikes come at a politically sensitive time. With midterm elections scheduled for November 2026, healthcare affordability is emerging as a major campaign issue. Voters are expressing frustration with rising costs across the economy, and healthcare is no exception.

Democrats, who control the White House and Congress, are facing pressure to address healthcare costs. However, the party is divided over the best approach. Some lawmakers support expanding subsidies to cover more middle-income Americans, while others favor more comprehensive reforms, including a public option or drug price controls.

Republicans, who have long opposed the ACA, are using the premium hikes to argue for their alternative healthcare proposals. Some are calling for the repeal of the ACA's insurance regulations and a transition to a more market-based system.

However, no comprehensive legislation has amassed enough support to pass, and the status quo is likely to remain in place for the foreseeable future. This means that enrollees will continue to face rising costs, and the political debate over healthcare is likely to intensify.

What's Next: Rate Finalization and Open Enrollment

Next year's rates will be finalized later in the summer, but KFF's analysis provides an early glimpse at what insurers are proposing. The report measured insurers' premium increases as an average across all types of plans — bronze, silver, gold and platinum.

State and federal regulators will review the filings and may push back on increases they deem excessive. In some cases, insurers may be required to modify their proposals before final approval.

Open enrollment for 2027 ACA coverage will begin in November 2026, at which point enrollees will be able to see the final rates and choose their plans. For many middle-income Americans, the sticker shock of the new rates will be significant.

Expert Perspectives and Reactions

Healthcare policy experts have weighed in on the proposed rate increases:

"The combination of subsidy expiration and rising healthcare costs is creating a perfect storm for middle-income enrollees," said one healthcare policy analyst. "The 14% median increase is a significant burden for families who are already struggling with broader inflationary pressures."

Consumer advocates have expressed concern about the impact on unsubsidized enrollees, calling on policymakers to find solutions. "These rate increases show why the subsidy cliff is a critical flaw in the ACA," said a spokesperson for a consumer advocacy group. "Middle-income families need relief, and policymakers must act to provide it."

Insurers, meanwhile, defend the rate increases as necessary to cover rising costs. "Our proposed rates reflect the reality of the healthcare market," said a representative of one insurer. "Medical costs are rising, and we must adjust our premiums to ensure we can continue to provide quality coverage to our enrollees."

Broader Implications for the U.S. Healthcare System

The ACA premium hikes have broader implications for the U.S. healthcare system:

Affordability crisis: Healthcare affordability is already a top concern for many Americans. Rising premiums will only exacerbate this crisis, potentially leading to higher uninsured rates.
Adverse selection: The departure of healthier enrollees from the marketplace could lead to a further deterioration of the risk pool, driving even higher premiums in future years.
Political pressure: The rate increases will likely intensify political pressure on lawmakers to address healthcare costs, but partisan divisions may prevent meaningful action.
Impact on small businesses: Many small business owners rely on the individual market for their health insurance. Rising premiums could create significant financial strain.
Health outcomes: Higher premiums may lead some enrollees to forgo coverage or reduce utilization of care, potentially harming health outcomes.

Conclusion

The KFF analysis of ACA premium rate filings reveals a troubling trend: two consecutive years of double-digit premium increases are leaving middle-income Americans — those who earn too much to qualify for subsidies — particularly vulnerable. The 14% median proposed increase for 2027, on top of the 20% jump in 2026, underscores the growing affordability crisis in the U.S. healthcare system.

The root causes are complex: rising healthcare costs across the sector, the expiration of enhanced subsidies, and the resulting adverse selection as healthier enrollees depart the marketplace. While subsidized enrollees are protected from the full impact, middle-income families face the full brunt of the increases.

The policy response has been inadequate. While lawmakers have proposed various reforms, no comprehensive legislation has gained enough support to pass. This means that enrollees are likely to face another year of rising costs, and the political debate over healthcare is likely to intensify.

For millions of Americans, the proposed premium increases are more than just a statistic — they represent a real strain on household budgets. As the final rates are set and open enrollment begins, many will face difficult choices about their healthcare coverage.
