Car Insurance Cost Calculator

What actually drives the cost of car insurance

Nationally, car insurance averages about $646 a year for state-minimum liability coverage and $2356 a year for full coverage, according to NerdWallet's August 2026 pricing data. That national figure hides a lot, though: two of the biggest levers on your actual premium are which state you live in and what kind of vehicle you drive.

State is the single largest factor. Minimum coverage requirements, accident and theft rates, the cost of medical care and vehicle repairs, the local litigation environment, and weather-related claim frequency (hail, flooding, hurricane exposure) all vary significantly by state.

Louisiana, New Jersey, and Florida price well above the national average for these reasons, while states like Wyoming and Vermont price well below it.

Coverage level is the biggest lever you control directly. State-minimum liability coverage pays for injuries or damage you cause to someone else and meets your state's legal requirement, but it pays nothing toward your own vehicle.

Full coverage adds collision and comprehensive protection on top, which is why it costs meaningfully more everywhere, and why it usually only makes sense to carry on a vehicle worth enough to be worth repairing or replacing.

Vehicle type is a real factor too, though a smaller one than state. According to MoneyGeek's 2026 body-style pricing comparison, a sports car costs roughly double what a comparable sedan costs to insure, driven by higher accident severity, higher theft rates, and a typically younger driver demographic for that body style.

A pickup truck, by contrast, typically costs somewhat less than a sedan to insure for the same driver.

This calculator deliberately does not model your age or driving record, two factors that can move your premium as much as state does. For that side of the picture specifically, the auto insurance cost by age and driving record calculator covers it directly, using this same kind of national pricing data.
