U.S. consumers are bracing for substantial health insurance premium increases in 2027, driven by a combination of persistent inflation, growing utilization of GLP-1 weight-loss medications, and the expiration of enhanced Affordable Care Act subsidies. According to industry experts, these factors are elevating costs across the healthcare system and placing additional strain on household budgets during an already difficult economic period.
Jonathan Oberlander, a professor of health policy and political science at the University of North Carolina at Chapel Hill, warned that cost burdens will extend beyond monthly premiums to include higher deductibles and copayments. “They can expect to pay more,” Oberlander said, noting the impact on both employer-sponsored and individual marketplace plans.
Employer-Sponsored Plans Face Record Gains
Approximately 166 million Americans under age 65 receive coverage through their employers. In 2025, the average worker contributed $6,850 toward annual premiums, while employers covered over $20,000 per worker, according to the Kaiser Family Foundation (KFF).
Looking ahead, consulting firms project historic spikes in employer healthcare costs for the coming year. Mercer estimates that benefit costs will rise by 8.2% per worker, marking the largest increase since 2003. WTW forecasts an 11.1% jump, the steepest in over two decades, while Aon anticipates a 9.5% rise. Aon described this trend as the fourth consecutive year of elevated healthcare costs, highlighting one of the most sustained periods of health care inflation employers have experienced in decades.
Nearly 60% of employers plan to implement cost-cutting measures in 2027, such as raising deductibles, according to a Marsh survey of over 1,800 companies. While higher deductibles may help curb premium hikes, they shift more financial responsibility to workers when they seek care. Matt McGough, an ACA policy analyst at KFF, noted that consumers are squeezed through multiple avenues, not just premiums.
ACA Marketplace Premiums Surge
In the individual market, insurers have proposed a median premium increase of 15% for 2027 across 276 carriers, according to KFF. If approved, this would mark the second straight year of double-digit hikes, following an 18% median proposed increase last year that resulted in a 20% finalized rate.
For many enrollees, premium tax credits shield them from the full brunt of these increases by capping costs as a percentage of income. However, individuals earning above 400% of the federal poverty line do not qualify for subsidies and will face the full price hike. Furthermore, the expiration of enhanced subsidies contributed to a 58% average increase in premiums for ACA enrollees from 2025 to 2026, pushing monthly costs to $178 from $113. Deductibles also reached a record high of $3,786 in 2026.
Key Drivers of Rising Costs
Several structural and market forces are fueling the inflation in health care spending. Sunit Patel, U.S. chief actuary for health and benefits at Marsh, identified the rapid adoption of GLP-1 drugs as a major factor, estimating that rising utilization accounts for about one percentage point of overall employer cost growth. Some employers have responded by dropping coverage for these medications entirely to achieve immediate savings.
Broader economic conditions also play a significant role. McGough pointed to persistent general inflation and healthcare labor shortages, which drive up wages and operational costs for insurers. Additionally, the consolidation of hospital systems and medical practices has reduced competition, allowing larger entities to negotiate higher reimbursement rates from insurers.
Oberlander suggested that the sharp cost increases over the past two years may signal the end of a roughly two-decade period of relative moderation in health spending growth. While the baseline costs were already high, the current trajectory indicates a significant shift in the economic landscape for American health insurance consumers.
