What Affects Your Car Insurance Rate?

Insurers weigh dozens of factors. These six drive the biggest differences in monthly premiums.

Age and Experience

Teen drivers (16-19) pay 2-3x the adult average. Rates fall sharply through the mid-20s and remain low until around age 70.

Location (State and ZIP)

State regulations, litigation rates, weather, and uninsured driver prevalence all affect premiums. The same driver pays 3x more in Louisiana than Maine.

Driving Record

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.

Coverage Level

Liability-only costs roughly half of full coverage. Lenders require full coverage on financed vehicles.

Vehicle Type

Sports cars and luxury vehicles cost 50-70% more to insure than economy cars. Safety ratings and theft statistics also matter.

Credit Score

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.

Why is my car insurance so high?

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.

Which state has the cheapest car insurance?

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.

How can a teen driver get cheaper car insurance?

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.

Does credit score affect car insurance rates?

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.
