Beating the Trend – How Employers Can Control Rising Healthcare Costs without Cutting Benefits

November 19, 2025

Rising Costs, New Pressures

Employer healthcare costs are poised to rise sharply. Mercer's National Survey of more than 1,700 U.S. employers projects a 6.5% year-over-year increase in total health benefit cost per employee (PEPY) for 2026 — driven largely by high-cost therapies such as GLP-1 drugs and advanced cancer treatments.

The Limits of Traditional Cost Control

Increasing employee cost-sharing and plan tweaks may ease short-term pressure, but they don't address the underlying drivers. The cost curve keeps climbing.

A Smarter Path Forward

Employers beating trend apply operating discipline and vendor accountability to flatten costs while protecting benefits. That means:

  • Continuous claims monitoring with timely alerts to identify risks early and prevent avoidable costs
  • Holding TPAs, PBMs, and networks accountable to contract terms and performance guarantees
  • Demanding transparency and measurable results from vendor partners

Case Study: Fortune 100 Healthcare Organization, 65,000+ Employees

Our client substantially reconfigured their vendor ecosystem in 2023. Continuous monitoring and proactive improvements were essential to maximizing plan performance — cost of care, quality of care, and member satisfaction. By holding vendors accountable, improving care, and continuously improving the plan, the client has been able to:

  • Beat industry projected per-employee-per-year (PEPY) costs every year by 10% on average, since 2023
  • Project 2026 PEPY at a 3% increase from prior year, below Mercer's projected 6.5% increase
  • Improve employee cost share by limiting premium growth to 2% — less than half of the market increase
  • Achieve $320 million (projected) in accumulated savings through the end of 2025
Moving from reactive cost-shifting to proactive oversight lets employers beat trend and protect employees.
