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. Learn more about what affects your car insurance rates beyond just credit.

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. Insurance scores also use different ranges — for example, LexisNexis Attract scores range from 200 to 997, while standard FICO scores run from 300 to 850. According to the NAIC, approximately 95% of auto insurers use credit-based insurance scores in states where the practice is permitted.

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. Critically, insurers cannot use your credit-based insurance score as the sole factor for denying coverage or setting rates in most states.

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. Understanding how car insurance premiums are calculated can give you deeper insight into every variable that shapes your rate.

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 have grown even more dramatic in recent years, with the widening gap between standard and high-risk car insurance rates becoming a major issue in 2026. According to H2 2025 data, low-credit driver rates rose 22% — while clean-record drivers actually saw a slight dip.

The Numbers: Bad Credit vs. Good Credit

According to the latest 2026 data, drivers with poor credit pay an average of 76% to 109% more for full coverage than drivers with excellent credit. The Zebra's analysis of 61 million car insurance rates found that drivers with poor credit pay about $2,729 per year compared to $1,308 for those with exceptional credit — a difference of approximately $1,421 per year. Bankrate's April 2026 analysis puts the annual gap even higher, at roughly $2,040 for full coverage (poor credit: ~$4,740/year vs. good credit: ~$2,697/year). On a monthly basis, bad-credit drivers pay an average of $204 more per month than those with good credit. In some states, the gap is far more extreme.

The impact varies dramatically by state:

Improving your credit by just one tier (e.g., Poor to Fair) can reduce your car insurance premium by an average of 17% or $355 per year, according to The Zebra's analysis. Moving from poor to average credit can save approximately $489 or 18% per year.

States That Ban or Restrict Credit Scoring for Car Insurance

Not every state allows insurers to use credit scores freely. Several states 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 — or only in very limited ways. Understanding how car insurance rate regulation works by state helps you know what consumer protections are in place where you live.

States With a Full Ban

• California — Insurers are fully prohibited from using credit in underwriting or rating auto policies (via Proposition 103).
• 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)

New Legislation to Watch in 2026

As of April 2026, several states have active proposed legislation that could expand restrictions on credit-based insurance scoring:

• Iowa (House File 2259) — Would prohibit credit scores for auto, snowmobile, and RV policies, effectively aligning Iowa with ban states.
• Missouri (Senate Bill 852) — Would ban credit scores from determining auto insurance rates, with an effective date of August 28, 2026; currently referred to committee.
• New York (Assembly Bill A10524, March 2026) — Would ban credit scores, small-area ZIP codes, and income as auto insurance rating factors.

Six states in total advanced anti-credit-scoring bills in their 2026 sessions. A federal bill was also reintroduced in 2025, though no federal ban is in effect as of April 2026. Regulation remains at the state level. Washington State's prior bans (2021–2022) were court-overturned, highlighting the legal complexity around these restrictions.

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 to lower what you pay. Also consider reviewing car insurance options for bad-credit drivers for a more detailed breakdown.

1. Shop Insurers That Weigh Credit Lightly

Not all insurers treat credit the same way. Some companies are significantly more competitive for drivers with lower credit scores. Based on 2026 rate data, here are the top options:

Usage-based insurance (UBI) programs are another powerful option. Programs like Nationwide SmartRide (up to 40% savings — with a 10–15% discount just for signing up), GEICO DriveEasy (up to 25–40%), State Farm Drive Safe & Save (up to 30%), and Progressive Snapshot (averaging $231/year in savings) can reduce your premium based on safe driving behavior — regardless of your credit. Pay-per-mile programs like Allstate Milewise and Nationwide SmartMiles can save low-mileage drivers significantly as well. For drivers in New Jersey, Pennsylvania, or Michigan, CURE Auto Insurance bases rates primarily on driving factors, not credit. Root Insurance uses smartphone telematics with no credit check and is available nationwide.

Learn more about high-risk car insurance options if poor credit has pushed you into the non-standard market. You can also review the best auto insurance companies for 2026 to compare overall ratings and pricing.

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 can translate to lower premiums faster than you might expect. Even a one-tier improvement can cut your annual premium by an average of $355. Learn more about how a quote can change once your credit is actually pulled during the underwriting process.

Fastest-impact steps:

• Pay down credit card balances — Lowering your utilization below 30% can improve your score within 30–60 days, since card balances are reported monthly
• 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 (~40%)
• 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. See how license points and violations affect your rates to understand the full picture of what's shaping your premium. You can also review why car insurance rates are rising in 2026 to stay informed on broader market trends.

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. According to the NAIC, approximately 95% of auto insurers use these scores in states where permitted. In most U.S. states, this score is a legal rating factor, meaning it directly influences your premium. Only a handful of states — California, Hawaii, Massachusetts, and Michigan — prohibit this practice entirely.

How much can bad credit raise my car insurance premium?

The impact is significant. Current 2026 data shows that drivers with poor credit pay an average of 76% to 109% more for car insurance than drivers with excellent credit. The Zebra reports a difference of approximately $1,421 per year based on analysis of 61 million rates, while Bankrate's April 2026 data puts the full-coverage annual gap at roughly $2,040. The exact increase depends on your insurer, state, and overall driving profile — with states like Nevada showing gaps as high as 199%. Review how premiums are calculated to understand all the factors at play.

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

Yes. Several insurers offer more favorable rates or no credit check for drivers with lower scores. CURE Auto Insurance (NJ, PA, MI) and Root Insurance (nationwide, telematics-based) do not use credit as a primary rating factor. Additionally, usage-based insurance programs from major carriers like Nationwide SmartRide, GEICO DriveEasy, State Farm Drive Safe & Save, and Progressive Snapshot can reduce the impact of credit by rewarding safe driving behavior instead — with potential savings of up to 30–40%. Learn more about car insurance options for bad-credit drivers for a full breakdown of your options.

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, the fastest route is to shop for new quotes — insurers pull a fresh score during the quoting process, so you can capture savings immediately rather than waiting for renewal. See why your car insurance quote may differ from the final price to understand how your credit score gets applied during underwriting.

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 at AnnualCreditReport.com 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 available.
