CarInsurance.com Insights

  • In most states, car insurance companies are generally allowed to raise premiums if you have bad credit, because credit-based insurance scores are widely used to assess risk.
  • States like California, Massachusetts, Michigan and Hawaii prohibit insurers from using credit information to set rates, meaning your credit score won’t affect premiums.
  • Insurers typically check your credit when you apply and at policy renewal, so a drop in your credit score can lead to higher premiums over time.

In most states, it is legal for car insurance companies to raise your premiums if you have a poor credit score. Insurers use credit-based insurance rates to determine the likelihood of you filing a claim.

However, a few states, including California, Massachusetts, Michigan and Hawaii, prohibit using credit information when setting car insurance rates. If you live in a state where it’s allowed, your premium may increase if your credit score drops.

How often do insurance companies check your credit score?

Insurance companies typically check your credit scores when you apply for a new policy or when your policy is up for renewal. It helps them assess your risk profile and determine your premium.

When applying for auto insurance, the insurer might run a credit check as part of the underwriting process. Some insurers periodically review your credit score when your policy is renewed, often annually, to adjust your rate if your credit profile has significantly changed.

Do all insurance companies use credit scores?

Not all insurance companies use credit scores to calculate car insurance rates, but many do. Credit-based insurance rates are standard because they help insurers predict the likelihood of future claims. However, whether or not an insurer uses credit information depends on the company’s policies and state laws.

Some insurers may rely heavily on credit scores as a rating metric, while others might emphasize driving history, vehicle type, location and other factors.

Sophie’s wise words

Your credit score is just one factor. Shopping around and comparing quotes from at least three insurers can help you find affordable coverage, even with poor credit. Because insurance companies weigh financial risk differently, exploring your options is the best way to find lower rates without sacrificing coverage.

How a poor credit score can affect your car insurance rate

A poor credit score can significantly increase your car insurance rates. Many insurance companies use a credit-based insurance score to help determine how much risk you pose as a policyholder. 

Drivers with poor credit are often charged much higher premiums than those with good or excellent credit. If your credit score drops over time, your insurer may increase your premium at renewal. On the other hand, improving your credit could lower your rates with some companies.

If you have a poor credit score, it’s worth shopping around. Insurers weigh risk differently, and some may offer better rates than others.

Frequently Asked Questions: Poor credit

Can my car insurance go up if my credit score drops?

Yes, your auto insurance rate can increase if your credit score drops significantly. Many insurers run a credit check when your policy is up for renewal to update your credit-based insurance score. If your score has fallen, the insurer may classify you as a higher risk and raise your premium accordingly.

Which states ban credit scores for car insurance?

California, Hawaii, Massachusetts and Michigan strictly prohibit insurance companies from using credit scores to determine car insurance rates. If you live in one of these four states, insurers must rely on other factors, such as your driving record, vehicle type and coverage limits, to calculate your premium.

Can an insurance company deny coverage due to bad credit?

No, an auto insurance company cannot deny you coverage solely because you have a bad credit score. While a poor credit history will almost certainly result in significantly higher premium rates, regulations prevent insurers from refusing you a policy outright based on your finances.
