Does Your Credit Score Affect Car Insurance Rates?

In most of the country, your credit history quietly shapes your car insurance bill, often more than a speeding ticket would. Insurers in the majority of states use a version of your credit data to predict how likely you are to file a claim, and drivers with poor credit can pay dramatically more than identical drivers with excellent credit. Understanding how this works, where it’s banned, and how to limit its impact puts real money back in your control.

This guide explains how credit affects car insurance rates, what a credit-based insurance score actually is, which states ban or restrict the practice, your legal rights when credit raises your rate, and the practical steps that lower your premium whether or not your credit improves overnight.

Yes, Credit Affects Car Insurance in Most States

In most states, insurers check your credit when you apply for a policy and use it as a pricing factor. The industry’s reasoning: decades of actuarial data show that, as a group, drivers with lower credit scores file more claims, making them statistically more expensive to insure. The Federal Trade Commission has found credit-based insurance scores to be statistically valid predictors of claim likelihood, which is why an estimated 95 percent of auto insurers use them where allowed.

The financial impact is substantial. Drivers with poor credit commonly pay on the order of 40 to 100 percent more than comparable drivers with excellent credit, in many markets, poor credit raises rates more than an at-fault accident does. That makes credit one of the most powerful and least understood rating factors in auto insurance. The practice is controversial, critics argue it penalizes low-income drivers for reasons unrelated to driving, and several states have banned it, but in most places it remains a central part of how your premium is set.

What a Credit-Based Insurance Score Is

Insurers don’t actually use your FICO score. They use a separate tool called a credit-based insurance score, built from the same credit report data but weighted with a different formula, one designed to predict insurance claims rather than loan repayment. According to the National Association of Insurance Commissioners, the typical weighting looks like this.

Notably, your income and employment aren’t part of the score. And because every insurer runs its own proprietary model, the same credit profile can produce very different quotes from one company to the next, which is exactly why shopping around matters so much for drivers with imperfect credit. One reassurance: insurance quotes use a soft credit pull, so getting quotes does not hurt your credit score. Use our car insurance calculator to think through your coverage while you compare.

States That Ban or Restrict Credit-Based Pricing

Four states ban insurers from using credit to price auto insurance: California (since 1988 under Proposition 103), Hawaii, Massachusetts, and Michigan (since its 2020 insurance reform). In these states, insurers price primarily on your driving record, mileage, vehicle, and similar factors, your credit simply doesn’t enter the equation. Michigan’s version has one nuance: credit can’t affect your rate or your insurability, but insurers may still use it when setting up monthly payment plans.

Several other states restrict the practice without banning it. Maryland allows credit in setting initial rates but prohibits using it to deny, cancel, or raise premiums at renewal. Oregon permits credit for new policies but not for cancellations or non-renewals. Utah imposes its own limits, and a few states like Texas and Colorado require insurers to justify how they use credit. Most states also prohibit credit from being the sole reason for adverse decisions. If you live in a ban state, this entire factor disappears from your bill; everywhere else, it pays to manage it.

Your Rights When Credit Raises Your Rate

Federal law gives you meaningful protections. Under the Fair Credit Reporting Act, if an insurer charges you more (or denies you) because of your credit information, it must send you an adverse action notice telling you so, identifying the credit bureau involved, and informing you of your right to a free copy of that credit report.

That notice is your cue to act. Request the free report and review it carefully, credit report errors are common, and disputing and correcting them can directly lower your insurance score and your premium. Many states also require insurers to offer exceptions for extraordinary life circumstances, such as a serious illness, divorce, job loss, identity theft, or the death of a spouse, that temporarily damaged your credit; if one applies to you, ask your insurer about an exception. And because rates based on credit are recalculated over time, you can ask your insurer to re-rate your policy after your credit improves rather than waiting for it to happen automatically.

How to Lower Your Premium If Your Credit Is Poor

You have two levers: improve the score and work around it. On the improvement side, the strategies mirror good credit habits, with payment history mattering most. Pay every bill on time (the single heaviest factor at roughly 40 percent), pay down balances to cut outstanding debt (another 30 percent), keep old accounts open to preserve history length, limit new credit applications, and dispute any errors on your reports. Improvements feed into your insurance score over time, and re-rating or re-shopping after six to twelve months of progress often shows real savings.

On the workaround side, shop aggressively, since insurers weigh credit very differently, the spread between quotes for a driver with poor credit can be enormous, and some carriers de-emphasize credit entirely. Usage-based and telematics programs price you substantially on how you actually drive, letting safe drivers earn meaningful discounts regardless of credit. Raising your deductible, maintaining continuous coverage, bundling policies, and keeping a clean driving record all help too. The combination of a few quotes and a telematics program is often the fastest path to a fair rate while your credit recovers.

Frequently Asked Questions

Does your credit score affect car insurance rates?

In most states, yes. Insurers use a credit-based insurance score, built from your credit report, as a major pricing factor, and drivers with poor credit can pay 40 to 100 percent more than comparable drivers with excellent credit. Four states ban the practice entirely.

Which states don’t allow credit to affect car insurance?

California, Hawaii, Massachusetts, and Michigan ban insurers from using credit to price auto insurance. Maryland, Oregon, and Utah restrict how it can be used (for example, allowing it for initial rates but not for cancellations or renewal increases).

What is a credit-based insurance score?

It’s a score built from your credit report data but weighted differently than FICO, designed to predict how likely you are to file a claim rather than repay a loan. Typical weighting: payment history 40 percent, outstanding debt 30 percent, history length 15 percent, new credit 10 percent, credit mix 5 percent.

Does getting car insurance quotes hurt my credit?

No. Insurance quotes use a soft credit inquiry, which doesn’t affect your credit score. You can shop as many insurers as you like without any credit impact, and shopping widely is especially valuable if your credit is imperfect, since insurers weigh it very differently.

How much more do drivers with poor credit pay?

Studies consistently show drivers with poor credit pay roughly 40 to 100 percent more than those with excellent credit for identical coverage, in many markets a bigger penalty than an at-fault accident. The exact gap varies by state and insurer, which is why comparison shopping matters.

What is an adverse action notice?

Under the Fair Credit Reporting Act, if credit information causes an insurer to charge you more or deny coverage, it must notify you, identify the credit bureau used, and inform you of your right to a free copy of that report, your opportunity to check for and dispute errors.

Can I get an exception if a life event hurt my credit?

In many states, yes. Insurers may be required to offer extraordinary life circumstance exceptions for events like serious illness, divorce, job loss, identity theft, or the death of a spouse. If a documented event damaged your credit, ask your insurer about an exception.

How can I lower my insurance if my credit is bad?

Shop several insurers (they weigh credit very differently), join a usage-based telematics program that prices your actual driving, pay bills on time and reduce balances to improve your insurance score, dispute credit report errors, and ask to be re-rated once your credit improves.

The Bottom Line

In most of the country, your credit history is one of the largest hidden inputs to your car insurance bill. Insurers convert your credit report into a credit-based insurance score, weighted toward payment history and debt, and price you accordingly, with poor credit often costing more than an accident would. Four states (California, Hawaii, Massachusetts, and Michigan) ban the practice, and several others restrict it.

Your protections matter: adverse action notices tell you when credit raised your rate and unlock a free credit report, disputing errors can directly cut your premium, and extraordinary life circumstance exceptions exist in many states for credit damaged by events beyond your control.

The playbook for drivers with imperfect credit is concrete: shop widely because insurers weigh credit differently, lean on telematics programs that reward how you actually drive, keep coverage continuous, and chip away at the score itself with on-time payments and lower balances, then re-shop. Credit-based pricing is a system you can work within, and often around, once you know it exists.
