Quick Answer
Yes, your credit score directly affects your car insurance rate in most U.S. states. As of July 2025, drivers with poor credit pay on average 76% more for auto insurance than drivers with excellent credit. Insurers use a specialized credit-based insurance score — distinct from your FICO score — to predict claim likelihood.
The relationship between credit score car insurance pricing is one of the most misunderstood factors in auto coverage. Insurers across the country use credit-based insurance scores to set premiums, and according to the Insurance Information Institute, the majority of U.S. auto insurers factor credit data into their pricing models. This practice is legal in 47 states — only California, Hawaii, and Massachusetts prohibit it entirely.
With auto insurance premiums rising sharply in 2024 and 2025, understanding every pricing lever — including your credit profile — has become essential for any driver looking to manage costs. For a broader look at what is pushing rates upward, see our breakdown of why insurance premiums are exploding.
What Is a Credit-Based Insurance Score and How Does It Work?
A credit-based insurance score is a numerical rating derived from your credit report, but it is not identical to your FICO credit score. It is specifically designed to predict the statistical likelihood that a driver will file an insurance claim, not to measure creditworthiness for lending purposes.
The score is calculated using data from the three major credit bureaus: Equifax, Experian, and TransUnion. The most widely used model is the LexisNexis Attract score, though FICO also produces an insurance-specific scoring model. Key inputs include payment history, outstanding debt, credit history length, new credit inquiries, and credit mix.
How Is It Different From a Regular Credit Score?
Your standard FICO score ranges from 300 to 850 and is used by lenders. Your insurance score uses similar underlying data but weights the factors differently. Payment history and total debt levels carry more influence in insurance models because they correlate most strongly with claim frequency, according to the Consumer Financial Protection Bureau.
Insurers do not have access to your income, net worth, race, or ZIP code when calculating credit-based scores — only the credit file data permissible under the Fair Credit Reporting Act (FCRA).
Key Takeaway: A credit-based insurance score is a separate model from your FICO score, built to predict claims — not loan repayment. It draws on data from Equifax, Experian, and TransUnion and is governed by the Fair Credit Reporting Act, meaning insurers can only use permissible credit file data to generate it.
How Much Does Your Credit Score Actually Affect Your Car Insurance Premium?
The financial impact of your credit score on car insurance rates is substantial — in many cases larger than the impact of a minor at-fault accident. Drivers with poor credit pay dramatically more than those with excellent credit, regardless of their driving record.
According to Bankrate’s 2024 rate analysis, the average annual auto insurance premium for a driver with excellent credit is approximately $1,700, while a comparable driver with poor credit pays roughly $3,000 — a difference of $1,300 per year. That gap compounds over multiple policy terms.
| Credit Tier | Average Annual Premium | vs. Excellent Credit |
|---|---|---|
| Excellent (750+) | $1,700 | Baseline |
| Good (670–749) | $2,012 | +18% |
| Fair (580–669) | $2,412 | +42% |
| Poor (Below 580) | $3,000 | +76% |
The gap varies significantly by insurer and state. Progressive, Allstate, and Farmers Insurance are among the carriers that weigh credit scores most heavily. USAA and Erie Insurance tend to apply smaller credit-based adjustments, according to industry rate filings.
“Consumers with poor insurance scores file more claims, and those claims tend to be more costly. The statistical correlation is robust enough that removing credit from rating would simply shift costs onto lower-risk policyholders.”
Key Takeaway: Poor credit can increase your car insurance premium by as much as 76% compared to excellent credit — a difference of over $1,300 per year, according to Bankrate’s 2024 analysis. Shopping carriers matters because the credit penalty varies widely between insurers.
Why Do Insurance Companies Use Credit Scores to Set Rates?
Insurers use credit-based scores because actuarial data shows a consistent statistical link between credit behavior and claim frequency — not because they are judging a driver’s financial character. The rationale is pure risk prediction.
A landmark Federal Trade Commission study found that credit-based insurance scores are effective predictors of risk under automobile policies. Drivers with lower scores tend to file more claims and generate higher claim costs, which drives the actuarial case for using credit data.
Is Credit Scoring in Insurance Fair?
This is genuinely contested. Critics — including consumer advocacy groups and several state regulators — argue that credit scores can act as a proxy for income or race, disadvantaging protected classes. The National Association of Insurance Commissioners (NAIC) has conducted ongoing reviews of potential disparate impact.
Defenders, including most major carriers and the American Property Casualty Insurance Association (APCIA), argue that the score is race-neutral under the FCRA, and that eliminating it would reduce pricing accuracy and raise costs for many lower-risk drivers. If you want a full picture of the factors that go into your premium, our guide to car insurance quotes explained covers each rating variable in detail.
Key Takeaway: The FTC confirmed credit-based insurance scores are statistically valid risk predictors, but the NAIC continues to scrutinize potential disparate impact. As of July 2025, only 3 states ban the practice for auto insurance — California, Hawaii, and Massachusetts.
How Can You Improve Your Credit Score to Lower Your Car Insurance Rate?
The most direct way to reduce a credit-penalty on your auto premium is to improve the underlying credit profile. Because insurance scores draw on the same credit bureau data as lending scores, the improvement strategies are nearly identical.
The highest-impact actions, consistent with guidance from Experian, are:
- Pay every bill on time — payment history is the single largest scoring factor.
- Reduce credit card balances below 30% utilization of your total available credit.
- Avoid opening multiple new accounts in a short window, which generates hard inquiries.
- Dispute errors on your credit report — the FCRA entitles you to free annual reports from AnnualCreditReport.com.
- Keep older accounts open to preserve average account age.
Meaningful score improvement typically takes 3 to 6 months of consistent behavior. Once your score moves into a higher tier, contact your insurer to request a re-rate, or shop new quotes. Our step-by-step guide on car insurance quote comparison shows exactly how to shop for a better rate efficiently.
You can also ask your insurer which credit scoring model they use. Some states require insurers to disclose this upon request, and knowing the model helps you prioritize the right credit behaviors.

Key Takeaway: Paying down balances to below 30% utilization and maintaining on-time payments for 3–6 months can move a driver into a higher credit tier, potentially saving hundreds annually on premiums. Combining credit improvement with strategic shopping maximizes the rate reduction.
Which States Do Not Allow Credit Score Car Insurance Pricing?
Three states — California, Hawaii, and Massachusetts — prohibit auto insurers from using credit scores as a rating factor. In those states, your credit profile has zero legal impact on your premium. Several other states impose partial restrictions or require additional disclosures.
Michigan passed legislation in 2019 restricting how credit data can be used in auto rating, though it did not implement a full ban. Washington State issued a temporary ban during the COVID-19 pandemic but allowed credit scoring to resume after a court challenge. Legislative pressure to restrict the practice has grown in several other states, including New York and Colorado.
If you live in a state that permits credit-based pricing, the impact on your premium is real and legally permitted. If you live in California, Hawaii, or Massachusetts, focus your rate-shopping energy on other variables — driving record, vehicle type, and coverage levels carry the most weight in those markets. For a complete overview of what shapes your insurance costs, our resource on the cost of insurance covers the full pricing picture.
Key Takeaway: Only 3 states — California, Hawaii, and Massachusetts — fully ban credit-based auto insurance pricing. In the other 47 states, your credit profile is a legally permitted rating factor that can swing your premium by hundreds of dollars annually, per Insurance Information Institute data.
Frequently Asked Questions
Does checking my credit score hurt my car insurance rate?
No. When an insurer checks your credit for rating purposes, it is classified as a soft inquiry under the Fair Credit Reporting Act, which does not affect your credit score. Only hard inquiries — triggered by applications for new credit — lower your score temporarily.
How often do car insurance companies check your credit score?
Most insurers check your credit-based insurance score at initial policy issuance and then again at each renewal, typically every 6 or 12 months. If your credit improves significantly between renewals, you can proactively request a re-rating in many states.
Can I get car insurance with no credit history?
Yes. Drivers with no credit file — often called “credit invisible” — are typically placed into a mid-tier risk category rather than the worst tier. Some insurers offer specialized programs for thin-file customers. Shopping multiple carriers is especially important in this situation.
What credit score is needed for the best car insurance rates?
Most insurers award their best credit-based pricing tier to drivers with a score of 750 or higher on standard FICO scoring scales. The exact threshold varies by carrier, but the 670–749 good credit range still produces rates meaningfully lower than fair or poor credit tiers.
Does credit score affect car insurance the same way in every state?
No. The three states that ban the practice — California, Hawaii, and Massachusetts — eliminate the credit factor entirely. In the remaining states, the weight given to credit varies by insurer and by state-specific regulatory guidelines. Some states require insurers to notify customers when an adverse action is taken based on credit data.
Is the credit-based insurance score the same as my FICO score?
No. A credit-based insurance score uses similar underlying data from your credit bureau file but is built using a different statistical model optimized to predict claim probability, not loan repayment. Your FICO score and your insurance score can differ meaningfully even though they draw from the same raw data.
