In 2026, over 70% of U.S. auto insurers use credit-based insurance scores to help determine car insurance premiums, according to the Insurance Information Institute. Many drivers don’t realize just how significant an impact their credit score can have on the cost of their car insurance, sometimes costing hundreds of dollars annually. This often-surprising factor can lead to higher premiums even for drivers with clean driving records. For consumers shopping for car insurance, understanding the relationship between credit scores and insurance rates is crucial. With so many variables influencing premium costs, credit scores represent a particularly opaque and sometimes controversial factor. State regulations vary on the use of credit in insurance underwriting, which adds another layer of complexity for policyholders. This comprehensive article will break down how credit scores affect car insurance pricing, explore the legal landscape across different states, analyze recent 2025-2026 data, and provide actionable advice on improving your credit profile to secure better insurance rates. We will also link to authoritative sources like the National Association of Insurance Commissioners and the Consumer Financial Protection Bureau to ensure you get accurate, trustworthy information.

What Is a Credit-Based Insurance Score and How Is It Different from Your Credit Score?

Many people confuse their traditional credit score with the credit-based insurance score used by auto insurers. While related, these scores are calculated differently and serve distinct purposes.

Credit score, such as the FICO score commonly used for lending decisions, evaluates your overall creditworthiness based on factors like payment history, credit utilization, length of credit history, credit mix, and new credit inquiries.

A credit-based insurance score is derived from credit report data but uses a unique algorithm designed to predict the likelihood of insurance claims. It typically weighs some factors differently, focusing on indicators statistically linked to insurance risk. For example, a high number of recent credit inquiries or late payments can disproportionately lower your insurance score.

According to a 2025 NAIC (National Association of Insurance Commissioners) report, about 41 states allow insurers to use credit-based insurance scores in underwriting car insurance policies, while 9 states prohibit or limit this practice due to concerns about fairness and potential discrimination (NAIC Credit-Based Insurance Scores Overview).

How Credit Scores Influence Car Insurance Premiums

Insurers use credit-based insurance scores as one of multiple factors to assess risk. Studies show that consumers with lower credit scores tend to file more claims, on average, which justifies higher premiums from an actuarial perspective.

The Insurance Information Institute reports that drivers with poor credit scores can pay between 20% to 70% more for car insurance than drivers with excellent credit, depending on the insurer and state regulations (III - Credit Scores and Insurance).

For example, a 2025 analysis by The Zebra found a national average annual premium of $1,502 for drivers with excellent credit, compared to $2,550 for those with poor credit — a difference of over $1,000 per year.

Key factors insurers consider related to credit include:

• Payment history and delinquencies
• Outstanding debt balances
• Length of credit history
• Number of recent credit inquiries
• Type of credit accounts

State Variations: Where Credit Scores Are Used or Banned in Auto Insurance

Insurance is primarily regulated at the state level, leading to significant differences in how credit scores are used. As of early 2026, the following outlines state positions:

• States Allowing Credit Scores: California, Florida, Texas, New York, and most others allow insurers to use credit-based insurance scores but require transparency and disclosure.
• States Restricting or Prohibiting Use: Massachusetts, Hawaii, California, and Maryland have restrictions or outright bans on using credit information in auto insurance underwriting.

California, for example, banned the use of credit scores for personal auto insurance in 2017 following concerns about disproportionate impacts on minority and low-income consumers. The California Department of Insurance reports that this ban has led to more equitable premiums without a significant increase in claim frequency (California DOI).

How Insurers Calculate Your Premium Using Credit Scores

While each insurer’s model is proprietary, the process generally involves integrating your credit-based insurance score alongside traditional underwriting factors such as:

• Driving record (accidents, violations)
• Vehicle type and age
• Geographic location
• Age and gender
• Annual mileage

Your credit score acts as a multiplier or risk adjustment factor. Lower scores often increase the risk factor, leading to higher premiums, while higher scores can lead to discounts.

For example, a 2026 report from the Consumer Financial Protection Bureau found that consumers with credit scores below 600 paid on average 50% more than those above 700, after controlling for other risk factors (CFPB Credit and Insurance Research).

Common Misconceptions About Credit Scores and Car Insurance

Many consumers misunderstand how credit impacts their insurance. Here are some clarifications:

• Credit Score Isn’t the Only Factor: Insurers weigh many elements; a low credit score doesn’t automatically mean denial or unaffordable premiums.
• Checking Your Own Credit Doesn’t Hurt: Insurance companies only see your credit report, not your credit score, and inquiries from you checking your own credit do not affect your insurance score.
• Paying Bills Late Impacts More Than Loans: Late payments, collections, or bankruptcies can all negatively influence your insurance score.

Practical Steps to Improve Your Credit Score for Better Car Insurance Rates

Improving your credit score can be an effective way to lower your car insurance premiums over time. Here are actionable tips:

1. Review Your Credit Reports Annually: Obtain free reports from AnnualCreditReport.com to check for errors or outdated information.
2. Pay Bills On Time: Timely payments are the single most important factor in credit scoring models.
3. Reduce Outstanding Debt: Lowering your credit utilization ratio can boost your score quickly.
4. Limit New Credit Applications: Avoid multiple credit inquiries in a short period.
5. Maintain a Long Credit History: Keep older credit accounts open where possible.

Improving your credit may take months or even years, but the payoff may be a significant reduction in your auto insurance costs.

What To Do If Your State Bans Credit Score Use in Auto Insurance

If you live in a state where credit scores cannot be used to set car insurance rates, other factors will weigh more heavily. These include your driving history, claims history, vehicle type, and mileage.

However, since insurers cannot use credit scores, you may find premiums more stable if your credit fluctuates. Still, having good credit is essential for other financial products, so managing credit well remains important.

How to Shop for Car Insurance With Credit Scores in Mind

Shopping for insurance when credit scores affect premiums requires strategy:

• Get Multiple Quotes: Because each insurer weights credit differently, comparing rates is critical.
• Ask About Discounts: Some insurers offer discounts for good credit or for enrolling in programs like autopay or bundling policies.
• Request a Credit-Based Insurance Score Disclosure: Some states require insurers to disclose your score and how it affects your premium.
• Work With Independent Agents: They can help find insurers more favorable to your credit profile.

Future Trends: Will Credit Scores Continue to Affect Car Insurance?

The debate over credit-based insurance scores continues as consumer advocates push for more regulation. Some states may expand bans, while others improve transparency. Additionally, some insurers are experimenting with alternative data such as telematics and social media signals to supplement or replace credit data.

For now, credit scores remain a significant factor for the majority of U.S. drivers in setting auto insurance premiums. Staying informed and proactive about your credit profile will continue to be a valuable strategy in managing insurance costs.
