Employer Health Insurance Costs Up 9.5% in 2026: What GLP-1 Drugs Mean for Your Premiums

# Employer Health Insurance Costs Up 9.5% in 2026: What GLP-1 Drugs Mean for Your Premiums

> **Quick answer:** Employer-sponsored health insurance costs are rising 9.5% in 2026 — the largest jump in 15 years — pushing average total costs past $17,000 per employee, according to Aon's survey of 1,000+ employers. GLP-1 drugs like Ozempic, Wegovy, and Zepbound now make up roughly 20% of all employer prescription drug spend, and total GLP-1 spending surged 50% in 2025. Workers can expect to see higher paycheck deductions, larger deductibles, and tighter prior authorization requirements in their plans — even if their employer absorbs most of the increase.

Employer health insurance costs are climbing faster in 2026 than at any point since the Affordable Care Act reshaped the market. This is not the ACA marketplace story — this is what is happening to the 160 million Americans who get coverage through a job. The Aon 2025 Health Survey, drawing on data from over 7.7 million employees and $120 billion in 2025 health care spend, projects a 9.5% cost increase this year. Mercer's parallel survey puts the total per-employee cost above $18,500. The culprit sitting at the center of both reports is the same: GLP-1 weight-loss medications and the employers trying to figure out whether covering them is sustainable.
