If your health insurance renewal came in this year and the number made you pause, you are not imagining it. Small businesses with ACA-compliant plans are facing a median premium increase of 11 percent for 2026, according to a Peterson-KFF analysis of filings from 318 insurers across all 50 states. Some plans are going up 20 percent or more. This is not the usual 3 to 4 percent annual bump most owners budgeted around for the past decade. Understanding what is driving these increases is the first step to managing them.
The Main Reasons Costs Are Going Up
The single largest driver is the underlying cost of medical care itself. Insurers consistently estimate that healthcare costs are rising approximately 9 percent in 2026, covering hospitalizations, physician services, and prescription drugs. Part of that is inflation working through the system, and part of it is a shortage of healthcare workers that has forced hospitals and clinics to pay significantly more to attract and retain staff. When provider labor costs go up, those costs move into the rates insurers pay, and then into the premiums you receive at renewal.
Prescription drug spending is the second major factor, and it is accelerating faster than medical costs overall. Pharmacy benefit spending now makes up 24 percent of total health spending, up from 21 percent in 2021. The biggest single contributor is GLP-1 medications used for diabetes and weight management. Twenty-seven of the insurers reviewed in detail by KFF specifically mentioned GLP-1 drugs as a factor pushing premiums higher. Drug spending in the U.S. grew by $50 billion in a single year, an 11.4 percent increase. Some carriers have responded by excluding GLP-1 coverage for weight loss purposes in 2026, though that decision creates its own employee relations complications.
Hospital and provider consolidation is a third factor that does not get enough attention. When large health systems merge or acquire independent practices, competition decreases and reimbursement rates go up. Insurers have less leverage in negotiations, and those higher rates flow directly into your premium. This trend has been building for years and is now a structural part of why costs keep rising regardless of what else is happening in the economy.
The small group market itself is also becoming more expensive to be in. Enrollment in small group plans dropped 11.9 percent in 2024, and insurers are projecting another 10 percent decline for 2026. When healthier businesses leave traditional group plans for self-funded arrangements or individual market alternatives, the remaining risk pool skews sicker and more expensive. Insurers respond by raising rates further, which pushes more businesses to leave, which raises rates again. For small employers who stay in traditional group coverage, this cycle is part of what is driving increases that outpace both wages and general inflation.
What This Means for Your Business Right Now
The average employer health insurance cost per employee is on track to surpass $17,000 in 2026, a 9.5 percent jump from 2025. For a business with 20 employees, that is $340,000 per year before any other compensation expense. Benefits administration decisions you make this year have direct budget consequences that compound over time.
Only about one in three small businesses currently offers any health coverage to employees. For those that do, the pressure to reduce coverage levels, shift more cost to employees, or exit group plans entirely is becoming a real business conversation rather than a theoretical one. That creates a retention risk that has to be weighed alongside the cost pressure. Workers who lose meaningful health coverage will look elsewhere, and in the current labor market, that is a real cost even if it does not show up on a premium invoice.
There are practical options worth evaluating. Individual Coverage Health Reimbursement Arrangements (ICHRAs) allow employers to set a fixed monthly contribution and let employees purchase their own coverage, giving business owners cost predictability regardless of what premiums do. ICHRA adoption jumped 34 percent among employers with 50 or more employees between 2024 and 2025. Level-funded plans, which function similarly to self-insurance but with stop-loss protection, can work well for businesses with healthier workforces. High-deductible plans paired with employer-seeded Health Savings Accounts remain a common middle-ground strategy for employers who want to keep group coverage but reduce premium exposure.
None of these options is the right fit for every business, and the wrong choice creates its own costs in employee dissatisfaction and administrative burden. Benefits administration support and HR outsourcing can help you model the actual cost difference between your current plan and alternatives before you commit to a change.
Action item: Before your next renewal date, pull your claims utilization data from your current carrier and ask for a comparison between your traditional group plan, a level-funded option, and an ICHRA model. If your broker cannot provide that comparison in writing, find one who can.
