Employers Are Bracing for the Highest Health Benefit Cost Increase in 15 Years, a Projected 6.5% Increase in 2026, According to Mercer
According to Mercer’s analysis of survey responses from over 1,700 US employers, the total health benefit cost per employee is expected to rise 6.5% on average in 2026 – the highest increase since 2010 – even after accounting for planned cost-reduction measures. If employers did not make any changes to their current plans, the overall average increase would have been nearly 9%.
Based on the projections, 2026 will be the fourth consecutive year of elevated health benefit cost growth following a decade of moderate annual increases averaging only about 3%, signaling mounting pressure on employers’ healthcare budgets.

Higher prices and higher utilization are converging to drive up cost
According to
Some price pressures are ongoing. Advances in diagnostics and therapeutics, such as cancer treatments and weight-loss drugs, produce better outcomes. However, they typically cost more than the treatments they replace. In addition, the continuing consolidation of providers into fewer, larger health systems has given them greater ability to work with insurers in setting reimbursement levels.
More recently, inflation across the general economy, including higher wages in the healthcare sector, has contributed to price increases.
Virtual services make it easier to seek care, which may contribute to higher utilization
Utilization rates for various health services have been rising over the past two years, according to
Employers’ response to faster cost growth
The survey indicates that 59% of employers will make cost-cutting changes to their plans in 2026 – up from 48% making changes in 2025 and 44% in 2024. Generally, these involve raising deductibles and other cost-sharing provisions, which can lead to higher out-of-pocket costs for plan members when they seek care. But many will also pursue strategies to slow cost growth without shifting cost to employees.
When employers were asked to identify top priorities for managing health programs over the next few years, the two most common were cost management strategies: “Greater focus on managing high-cost claims,” followed by “Measuring the performance of health programs to ensure they provide value.” However, third on the list was a benefit enhancement: “Making behavioral healthcare more accessible,” with about two-thirds of large employers (those with 500 or more employees) planning to prioritize this strategy.
“Employers have been unwavering in their commitment to supporting employees’ mental health since the early days of the pandemic,” says
Considerations for employees during open enrollment this year
Employees could expect paycheck deductions for health coverage to rise 6% to 7% on average in 2026, as their share of the premium typically increases proportionally with overall plan cost, according to
Since most employers offer more than one medical plan option, employees should carefully weigh premium cost and cost-sharing provisions to determine which plan best meets their needs. If available, employees may also consider a non-traditional, high-performance network plan designed to help patients access providers pre-selected on the basis of quality and cost, which may offer lower out-of-pocket costs. A recent survey revealed that over one-third of large employers will offer some type of non-traditional plan in 2026.
