How Your Credit Score Impacts Your Car Insurance in the US

When you shop for car insurance, you probably expect your driving record, the type of car you drive, and your zip code to dictate your rates. But there is a silent factor working behind the scenes that catches many American drivers off guard: your credit score.

In most US states, auto insurers use your credit history as a primary tool to determine how much you will pay for coverage. Let’s dive into exactly how your credit score affects your premiums and what you can do to keep your costs down.

The Shocking Cost of Poor Credit

Industry data consistently shows that drivers with poor credit can pay over 100% more for full coverage car insurance compared to drivers with excellent credit. Insurers believe that individuals with poor credit are statistically more likely to file future claims.

Credit Tier	FICO Score Range	Avg. Annual Premium
Excellent	740 - 850	$2,318
Good	670 - 739	$2,697
Average	580 - 669	$2,947
Poor	300 - 579	$4,745
