Rising Costs of Employer-Sponsored Health Insurance in 2025
Overview of Health Insurance Costs
According to Mercer’s recent 2025 National Survey of Employer-Sponsored Health Plans, the average cost of employer-sponsored health insurance reached $17,496 in 2025. This marks a 6% increase from the previous year, surpassing both inflation and wage growth rates. Projections indicate that costs will further rise by 6.7% in 2026, bringing the average cost per worker to $18,500. A significant factor contributing to this increase is the sharp rise in prescription drug spending, particularly for expensive GLP-1 weight-loss medications. The survey noted that prescription drug spending rose by an average of 9.4% among large employers, defined as those with 500 or more employees. Additionally, coverage for GLP-1 medications increased to 49% in 2025, up from 44% in the previous year.
Insight into Healthcare Cost Trends
The trend of escalating healthcare costs continues to be a pressing issue. A recent report from KFF’s 2025 Employer Health Benefits Survey revealed that family premiums for employer-sponsored health insurance increased by 6%, or $1,408, from the previous year. On average, family premiums reached $26,993 in 2025, which is notably higher than the cost of a new Toyota Corolla Hybrid, as highlighted by KFF President and CEO Drew Altman. Additionally, HUB International’s 2026 Benefits Cost Trend report projected an increase in medical and prescription benefit costs of 8% to 10% next year, attributed in part to the usage of high-cost drugs, including GLP-1s and autoimmune medications.
Potential Solutions and Strategies for Employers
Despite the rising costs, there are optimistic perspectives for employers. A global health and risk leader at WTW noted that while investment in technologies, including artificial intelligence, may lead to higher costs initially, these innovations hold the potential for reducing healthcare cost trends in the long term. In the interim, employers can adopt various strategies to manage these costs. Ed Lehman, Mercer’s U.S. Health and Benefits Leader, emphasized the importance of minimizing increases in paycheck deductions while ensuring that employees can afford necessary care.
To achieve this, employers can provide more medical plan options, encourage the selection of high-performing providers, and offer specialized health programs. The survey found that in 2025, 32% of large employers offered a standalone specialized diabetes program, 28% provided a musculoskeletal program, and 23% included a fertility program. These programs are often low-cost or free and are typically delivered virtually, according to Mercer’s survey of 2,010 employers.
