Insurers weigh dozens of factors. These six drive the biggest differences in monthly premiums.
Teen drivers (16-19) pay 2-3x the adult average. Rates fall sharply through the mid-20s and remain low until around age 70.
State regulations, litigation rates, weather, and uninsured driver prevalence all affect premiums. The same driver pays 3x more in Louisiana than Maine.
A single at-fault accident typically raises premiums 45% for 3 years. A DUI can double your rate and may require an SR-22 certificate.
Liability-only costs roughly half of full coverage. Lenders require full coverage on financed vehicles.
Sports cars and luxury vehicles cost 50-70% more to insure than economy cars. Safety ratings and theft statistics also matter.
In 47 states, your credit-based insurance score can raise or lower your premium by up to 100%. Only CA, HI, and MA prohibit this practice.
The national average cost of car insurance is $212 per month, or $2,543 per year in 2026. This covers full-coverage insurance. Liability-only coverage averages around $72 per month.
Car insurance rates are higher if you are young (under 25), have accidents or tickets on your record, live in a high-risk state like Florida or Louisiana, drive a luxury or sports vehicle, or carry full-coverage rather than liability-only.
Maine has the cheapest car insurance at around $85/mo ($1,020/yr), followed by New Hampshire ($91/mo), Iowa ($107/mo), and Idaho ($99/mo). These states benefit from low population density, fewer severe weather events, and lower litigation rates.
Louisiana is the most expensive state at around $270/mo ($3,240/yr), followed by Florida ($260/mo), Michigan ($248/mo), and Kentucky ($241/mo). High litigation rates, extreme weather, and uninsured driver rates all push premiums up.
Teen drivers can reduce costs by staying on a parent's policy, taking a defensive driving course, maintaining good grades (many insurers offer a good-student discount of 8-15%), choosing a safe, modest vehicle, and comparing quotes across multiple insurers.
In most US states, insurers use a credit-based insurance score to set premiums. Drivers with poor credit can pay 50-100% more than those with excellent credit for the same coverage. California, Hawaii, and Massachusetts prohibit using credit scores for auto insurance pricing.
