What Is a Credit-Based Insurance Score?

Most drivers know their credit score matters for loans and credit cards — but far fewer realize it plays a significant role in determining their car insurance premium. Insurers don't actually use your standard FICO score. Instead, they use a separate metric called a credit-based insurance score, and understanding the difference could save you a lot of money.

Credit-Based Insurance Score vs. FICO Score

A credit-based insurance score is a three-digit number calculated from the same underlying credit report data as your FICO score, but it is weighted very differently. While a FICO score is designed to predict whether you'll repay a debt, an insurance score is designed to predict whether you're likely to file a claim — and how costly that claim might be.

Here's how the two scoring models compare in their factor weighting:

One important note: neither score uses personal information like your income, race, gender, age, or job. However, your insurance score can change independently of your FICO score because the weighting and interpretation differ by insurer.

Why Do Insurers Use Credit Scores?

Multiple large-scale studies — including a Federal Trade Commission report — have confirmed a strong statistical correlation between credit behavior and the frequency and cost of insurance claims. Drivers with lower credit-based insurance scores are statistically more likely to file claims than those with higher scores. For insurers, this correlation justifies using the score as one of several rating factors alongside your driving record, vehicle type, and location.

How Much Does Credit Affect Your Car Insurance Rates?

The impact of credit on car insurance premiums is substantial — and often underestimated by consumers.

The Numbers: Bad Credit vs. Good Credit

According to 2026 data from ValuePenguin, drivers with poor credit pay an average of $412 per month for full coverage, while drivers with good credit pay significantly less — a difference of roughly $204 per month or over $2,400 per year. Bankrate's national analysis shows that poor credit drivers pay, on average, 76% more for car insurance than those with good credit. Some studies place that figure as high as 88% more.

The impact also varies dramatically by state:

A drop in credit from "good" to "poor" can add more than $2,000 per year to your insurance costs — more than the cost of a speeding ticket.

States That Ban or Restrict Credit Scoring for Car Insurance

Not every state allows insurers to use credit scores freely. Several have passed laws banning or heavily restricting the practice. If you live in one of these states, your credit won't affect your car insurance rate at all.

States With a Full Ban

• California — Insurers are fully prohibited from using credit in underwriting or rating auto policies.
• Hawaii — Credit ratings cannot be used in any underwriting standards or premium rating plans.
• Massachusetts — Credit information cannot be used for setting rates or underwriting new policies or renewals.
• Michigan — Insurers cannot use credit to deny, cancel, or determine auto insurance rates.

States With Restrictions (Partial Use Only)

As of early 2026, states like Iowa and Oklahoma have active legislation advancing to ban or restrict credit-based insurance scoring — so this list may grow. Understanding how your state's insurance regulations work can help you know your rights as a consumer.

What to Do If Your Credit Is Hurting Your Car Insurance Rates

Having poor credit doesn't mean you're stuck with sky-high premiums. There are several concrete steps you can take right now.

1. Shop Insurers That Weigh Credit Lightly

Not all insurers treat credit the same way. Some companies offer policies without credit checks or use telematics-based pricing instead:

• CURE Auto Insurance — Available in NJ, PA, and MI; rates based on driving factors, not credit
• Dillo Insurance — Texas-only, specifically designed for hard-to-insure drivers with no credit check
• Root Insurance — Uses smartphone-based driving behavior data with no credit check
• Direct Auto Insurance — Specializes in coverage for drivers with bad credit or poor driving history
• Usage-based programs (Allstate Drivewise, Nationwide SmartRide, GEICO DriveEasy) — Let your driving behavior reduce your premium regardless of credit

2. Improve Your Credit Score

The most powerful long-term solution is improving your underlying credit. Your insurance score is re-evaluated at renewal (every 6–12 months), so better credit translates to lower premiums sooner than you might expect.

Fastest-impact steps:

• Pay down credit card balances — Lowering your utilization below 30% can improve your score within 30–60 days
• Dispute errors on your credit report — Get your free report at AnnualCreditReport.com and challenge any inaccuracies
• Never miss a payment — Payment history is the heaviest factor in both credit and insurance scoring
• Avoid opening new credit accounts — Hard inquiries temporarily lower your score
• Keep old accounts open — A longer credit history works in your favor

3. Request Reconsideration From Your Insurer

Many insurers will reconsider your premium if your credit has improved or if your credit was negatively impacted by an extraordinary life event such as a job loss, medical emergency, or natural disaster. Here's how to request a review:

1. Contact your insurer or agent and ask them to re-run your credit-based insurance score
2. Ask what score range you currently fall in and what range qualifies for a lower premium tier
3. Document any life events that caused a temporary credit dip (divorce, illness, layoff)
4. Shop competing quotes — even if your current insurer won't budge, competitors may offer better rates
5. Review annually — make credit improvement a part of your annual insurance review cycle

Under the Fair Credit Reporting Act (FCRA), insurers are required to notify you if your credit information resulted in an adverse action on your policy — meaning a higher rate or a denial. If you receive such a notice, you have the right to know which credit bureau was used and to dispute any inaccurate information.

Frequently Asked Questions

Does my credit score directly affect my car insurance rate?

Not your standard credit score — insurers use a separate credit-based insurance score pulled from the same credit report data but weighted differently to predict claim likelihood. In most U.S. states, this score is a legal rating factor, meaning it directly influences your premium. The better your insurance score, the lower your rate, and vice versa. Only a handful of states like California, Hawaii, Massachusetts, and Michigan prohibit this practice entirely.

How much can bad credit raise my car insurance premium?

The impact is significant. National data from 2026 shows that drivers with poor credit pay an average of 76–88% more for car insurance than drivers with good credit — a difference that can exceed $2,000 per year for full coverage. In some states like Washington D.C. and Florida, the penalty for poor credit can nearly triple your premium. The exact increase depends on your insurer, state, and overall driving profile.

Are there car insurance companies that don't check credit scores?

Yes. A few insurers offer policies without a credit check, including CURE Auto Insurance (NJ, PA, MI), Dillo Insurance (TX), and Root Insurance (nationwide, telematics-based). Usage-based insurance programs from major carriers like Allstate, Nationwide, and GEICO can also reduce the weight credit plays in your final rate by rewarding safe driving behavior instead. See how to find cheap car insurance with bad credit for a full breakdown.

How long does it take for a credit improvement to lower my car insurance rates?

Credit utilization improvements can reflect in your score within 30–60 days since credit card balances are reported monthly. However, your insurer will typically re-evaluate your credit-based insurance score at your next renewal (every 6 or 12 months). If you've made meaningful credit improvements mid-policy, you can proactively ask your insurer to re-run your score or simply shop competing quotes to see if better rates are available now.

Can I dispute an insurance rate increase caused by my credit score?

Yes. The Fair Credit Reporting Act (FCRA) requires insurers to notify you when your credit report contributes to an adverse action, such as a premium increase. You can request the name of the credit bureau used, pull your free credit report to check for errors, dispute any inaccuracies directly with the bureau, and ask your insurer to reconsider your rate. If your credit drop was caused by a qualifying life event (job loss, medical crisis, divorce), many insurers have formal reconsideration processes for those circumstances.
