Total health benefit costs per employee across the United States are projected to increase by an average of 8.2% in 2027, according to preliminary survey data from global professional services firm Marsh. Based on feedback from more than 1,800 U.S. employers in the 2026 National Survey of Employer-Sponsored Health Plans, this surge represents the highest annual cost increase recorded since 2003 even after accounting for planned employer cost-mitigation strategies.
Without cost-management adjustments, participating organizations reported that expenses for their existing medical plans would surge by an average of 11%. The forecasted 8.2% rise marks the fifth consecutive year of elevated health benefit cost growth, following a decade of modest single-digit increases, and exceeds the 6.7% average growth rate projected for 2026.
Key Factors Accelerating Healthcare Expenditure Growth
Long-standing macroeconomic pressures such as advances in diagnostic technologies, expensive specialty therapeutics, health system consolidation, and reduced public sector reimbursement rates continue to push medical cost trends well past general inflation. However, emerging catalysts are driving cost growth to multi-decade highs.

Primary among these new drivers is the widespread adoption of GLP-1 weight-management medications. Additional contributing factors include the rapid integration of AI-assisted medical billing software which has increased both claim volumes and coding levels and larger-than-anticipated out-of-network provider settlements awarded under Independent Dispute Resolution processes.
“While the market for these medications is evolving in ways that could ultimately result in lower costs, some employers needing immediate cost relief chose to drop this coverage for next year,” says Mr. Patel. “Still, we estimate that rising GLP-1 utilization accounts for a full percentage point of the overall cost growth for 2027.”
Impact on Employee Paychecks and Benefit Design Strategies
To cushion financial impacts, 59% of surveyed employers intend to execute cost-cutting measures in 2027, such as raising deductibles and out-of-pocket maximums. Earlier findings from Marsh indicate that roughly two-thirds of large employers (organizations with 500 or more workers) expect to increase employee premium contribution shares, meaning many workers will see payroll deductions grow beyond the baseline 8.2% mark.
To balance cost containment with talent retention, organizations are increasingly introducing value-based, quality-focused coverage options:
Variable Copay Plans: 12% of large employers and 18% of enterprises with 20,000 or more employees plan to offer variable copay options, which feature low or zero deductibles when members select top-tier care providers.
Guiding Members to High-Quality Care: 58% of large employers cited directing employees toward higher-quality healthcare providers as a top management priority over the next few years, moving this strategy into their top three overall priorities.
Non-Traditional Medical Offerings: Over one-third of large employers plan to offer non-traditional medical structures, such as high-performance network designs.
“As very expensive new therapies for cancer and rare diseases reach the market, extremely high-cost claims have become more common. So on top of high costs, health plan sponsors are also dealing with more volatile costs, which can materially disrupt budgets and impact earnings, particularly for smaller employers,” says Mr. Patel.
Managing Volatility and High-Cost Catastrophic Claims
In addition to baseline inflation, managing high-cost claims remains the single highest operational priority for health plan sponsors. The introduction of gene therapies and specialized oncology treatments has increased the frequency of multi-million-dollar claims, introducing budget volatility for mid-sized and enterprise employers alike.
