Multiple consulting firms project substantial increases in employer healthcare costs for 2027, with estimates ranging from 8.2% to 11.1% per worker. This marks the largest annual increase since 2003 for some metrics and reflects one of the most sustained periods of healthcare inflation in decades. Employers are likely to pass these additional costs to workers through higher premiums, increased deductibles, and expanded out-of-pocket expenses.
Workers with employer-sponsored insurance already experienced a 7.9% jump in total healthcare costs during 2026, the fastest annual pace in a decade. Nearly 6 out of 10 employers plan to implement cost-cutting measures in 2027, particularly by raising deductibles. While higher deductibles may moderate premium increases, they shift more financial burden to workers who actually use their insurance. Deductibles and family premiums have grown 54% and 53%, respectively, over the past decade—significantly outpacing the overall inflation rate of 36%.
For the approximately 19.2 million Americans enrolled in Affordable Care Act marketplace plans, insurers have proposed a median 15% premium increase for 2027, continuing the pattern of double-digit hikes. Most ACA enrollees receive subsidies that cap their premiums as a percentage of income, largely shielding them from premium increases. However, roughly 1.6 million enrollees with incomes exceeding 400% of the federal poverty line have lost eligibility for subsidies and face the full unsubsidized premium amounts following the expiration of enhanced tax credits.
The surge in healthcare costs stems from multiple factors. A significant driver is increased utilization of GLP-1 medications for weight management, which consulting firm Marsh estimates accounts for approximately 1 percentage point of overall employer cost growth. This uptick follows roughly two decades of relative moderation in healthcare spending growth, and experts remain uncertain whether the recent acceleration signals a permanent shift in the trajectory of U.S. healthcare inflation.
