How is this calculated?
Each state figure is the NAIC 2023 combined average premium for that state, adjusted to current dollars using the national BLS Consumer Price Index for motor vehicle insurance. We apply the same national CPI multiplier to every state because the BLS does not publish state-level insurance CPI data. This means the relative ranking reflects actual 2023 differences between states, while the dollar amounts account for overall insurance inflation since then. See our full methodology.

Why Car Insurance Costs Vary So Much by State
The gap between the cheapest and most expensive states is over $107 per month, or more than $1,277 per year. That difference exists before any personal factors (age, driving record, credit) enter the picture.
Several forces drive these differences. States with no-fault insurance systems (Florida, Michigan, New Jersey, and others) tend to have higher premiums because insurers cover medical costs regardless of who caused the accident. Urban population density increases collision frequency: more cars on the road means more claims per driver. Litigation environments matter too; states where insurance lawsuits are common (Louisiana, Florida) see higher claim payouts, which get passed to policyholders as higher premiums.
Weather plays a measurable role. States in hurricane corridors, tornado alleys, and flood zones see higher comprehensive claim costs. Fraud levels, uninsured driver rates, and state regulatory environments (how aggressively states review and approve rate increases) also contribute.
What You Can Do About It
You cannot change your state overnight, but you can control how you shop within it. Rates for identical driver profiles vary by 50% or more between carriers in the same state, because each insurer weighs risk factors differently in their pricing models. Getting at least three quotes at every renewal is the single most effective way to avoid overpaying. Use our overpaying calculator to see how your profile compares, or check your state's minimum requirements to make sure you are carrying appropriate coverage.

Urban states with more traffic and higher vehicle density also see elevated claim frequency.
