But the average fluctuation is actually greater nationwide, where the difference between someone with excellent credit and another person with no credit could translate to as much as a 65 percent higher insurance cost for the individual with no credit.
WalletHub, which runs a financial information website for consumers, based its findings on insurance quotes from five of the largest auto insurance companies. WalletHub reported that Allstate has the biggest fluctuation in premiums -- 116 percent -- between customers at both ends of the credit spectrum while State Farm has the smallest difference, 45 percent.
Wyoming at 114 percent, Indiana at 110 percent and Maine at 109 percent were the states with the largest fluctuation in premiums between a motorist with excellent credit and one with no credit. California, Hawaii and Massachusetts were at the other end of that spectrum, with no difference in auto insurance costs based on credit scores.
WalletHub based its study on an experienced 36-year-old male driver who drives 16,000 miles a year in a 2008 Honda Accord LX four-cylinder sedan.
The coverage includes $50,000 for injury/death to one person, $100,000 for injury/death to more than one person, $50,000 for damage to property and $1,000 for medical coverage. The premium also includes $30,000 in coverage for collision with an uninsured motorist and $1,000 comprehensive coverage.
