Employer Health Costs Set to Jump 9.5% in 2027, Aon Says

Another Steep Climb in Employer Health Costs

Employers across the United States are bracing for one of the sharpest increases in health-benefit spending in decades. A new analysis from global risk and benefits consulting firm Aon projects that employer healthcare costs will rise 9.5% in 2027, pushing average per-employee spending above $19,000 347. Multiple outlets rounded the figure to roughly 10%, framing it as a near double-digit jump that will make 2027 another financially punishing year for companies and their workers alike 125.

The Wall Street Journal notes that this marks the largest health-insurance cost increase employers have faced in at least two decades, underscoring that this is not simply a continuation of routine annual increases but a notable acceleration 6. Coverage from Axios similarly frames the trend as persistent, describing near double-digit increases as an ongoing pattern rather than a one-year anomaly 1.

What's Driving the Increase

Aon attributes the surge primarily to two forces: rising medical utilization and the escalating cost of high-priced specialty drugs 347. As more employees seek care and as pharmaceutical treatments — particularly advanced and specialty medications — carry steeper price tags, the overall cost of employer-sponsored health plans climbs. Aon, described as the second-largest global insurance broker, based its projections on a broad risk analysis of employer health plans nationwide 5.

Why Hospitals, Not Just Insurers, Are Under Scrutiny

While insurers are often the public face of rising premiums, some commentary pushes back on that narrative. A Fortune analysis argues that before employers pass more costs onto workers through higher deductibles or premiums, they should first interrogate hospital pricing practices, since healthcare has become a growing operating expense — Mercer data cited in the piece shows roughly three-quarters of corporate CFOs now rank healthcare among their top five operating cost concerns 8.

Adding to that scrutiny, research highlighted by Anthony DiGiorgio points to hospital consolidation as a significant driver of higher healthcare costs. Studies from the University of Washington cited in this commentary suggest that hospital mergers reduce competition and contribute to price increases that ripple through paychecks and medical bills, complicating the common assumption that insurers alone bear responsibility for rising costs 9.

The Stakes for Employers and Workers

Taken together, the coverage paints a picture of a healthcare cost crisis with multiple contributing factors — utilization trends, drug pricing, and consolidation in the hospital sector — all converging at once. For employers, the choice ahead involves whether to absorb rising costs, shift more of the burden to employees through higher premiums and out-of-pocket expenses, or push back against pricing upstream, including negotiating harder with hospitals and health systems. For workers, the practical impact is likely to be felt directly in paycheck deductions and insurance costs in 2027, regardless of how employers respond.
