How much is Anthem raising small business rates?

The January 2027 number is what Anthem filed. The state hasn’t posted a final number yet, but in every earlier quarter the final number matched the filing.

The federal rate review site shows a lower figure for the same filing, 6.7%. That’s the average change in Anthem’s plan prices. The 10.9% is the average increase for the companies renewing this quarter, and it’s the number California publishes.

What Anthem small business plans cost in 2027

Anthem’s filing also shows the average monthly premium for companies renewing in early 2027, per person covered. That counts employees and any family members on the plan, and it’s the full premium before you split it with your employees.

An HMO keeps you in a set network of doctors and usually needs a referral to see a specialist. A PPO lets people see doctors outside the network, for a higher cost. Anthem’s HMOs cost less per person, but this year they’re going up faster.

Your own increase depends on your plan, your employees’ ages, and where your company is located. Anthem’s rate justification shows individual plans changing anywhere from 2.9% lower to 17.9% higher, and Anthem expects most people to see less than 15%.

Why is Anthem raising rates?

Anthem paid more in claims in 2025 than it had planned for, and that’s most of the increase. Its filing splits the 10.9% into parts. The 2025 claims account for 7.7 points. Shifts in which plans people are enrolled in add 1.3 points. Administrative costs add about 1 point, and so does risk adjustment, a federal program that moves money between insurers based on how healthy their members are.

The filing projects costs rising about 8.7% a year. Prescription drugs are climbing fastest, about 10.5% a year, and they were about a quarter of the cost of care for Anthem’s small business members in 2025. Hospitals are a big part of it too: Anthem’s costs for outpatient hospital care ran about 2.7 times what Medicare pays for the same services, and inpatient care about 2.2 times.

Anthem’s parent company, Elevance Health, told investors on its October 21 earnings call that it priced its employer plans for 2026 and 2027 expecting costs to grow at a low double-digit rate. The comment was about Elevance’s employer plans nationwide.
