Your credit history can affect your car insurance rate in many states, but insurers usually use a credit-based insurance score rather than the traditional credit score a lender uses. Whether credit can be considered, how it may affect your premium, and what consumer protections apply depend heavily on state law. Some states restrict or prohibit its use, while others allow insurers to use credit information as one of several rating factors.
Key Takeaways
- Many insurers use credit information when pricing auto insurance where state law permits it.
- A credit-based insurance score is different from the credit score typically used for mortgages, credit cards, and auto loans.
- Credit is generally only one part of the premium calculation; driving history, vehicle, location, coverage, and other permitted factors can also matter.
- State rules vary significantly. Some states restrict credit use much more heavily than others.
- If credit information contributes to an unfavorable insurance decision, federal law can give you important notice and credit-report rights.
How Credit Can Affect Your Car Insurance Rate
Where permitted, an insurer may use information from your credit history to help calculate a credit-based insurance score. That score can then become one factor in underwriting or rating your auto insurance policy.
Underwriting is the process an insurer uses to decide whether and under what conditions it will insure a risk. Rating is the process used to determine the premium charged for coverage.
If an insurer’s approved rating system treats your credit-based insurance score favorably, it may contribute to a lower premium. A less favorable score can contribute to a higher premium where applicable law allows it.
The important distinction: an insurer normally does not price your policy from credit alone. Your premium can also reflect your driving record, claims history, vehicle, location, mileage, coverage choices, deductibles, and other rating factors permitted in your state.
Credit Score vs. Credit-Based Insurance Score
The phrase “credit score” is often used loosely when discussing car insurance, but the score used by an insurer may not be the same number you see when applying for a loan.
| Feature | Traditional Credit Score | Credit-Based Insurance Score |
|---|---|---|
| Primary purpose | Estimate credit repayment risk. | Estimate insurance loss or claim risk. |
| Common use | Loans, mortgages, and credit cards. | Insurance underwriting or premium rating where allowed. |
| Data source | Information from your credit history. | Selected information from your credit history. |
| Calculation | Depends on the lender’s scoring model. | Depends on the insurer or insurance-scoring model. |
The two types of scores may rely on some of the same underlying credit-report information, but they are built for different purposes and can weigh that information differently. Knowing your consumer credit score therefore does not necessarily tell you your insurer’s credit-based insurance score.
What Credit Information May Be Considered?
The exact formula varies by scoring model and state law. Common credit-report characteristics that can appear in scoring systems include payment history, outstanding balances, account history, certain public-record information, and the types or number of credit accounts.
- Payment history: Late payments or delinquent accounts may be treated differently from a history of paying on time.
- Outstanding debt: Some models consider balances and how much available credit is being used.
- Length of credit history: The age of accounts can be relevant in some models.
- Account mix: The types and number of credit accounts may be considered.
- Certain adverse information: Bankruptcy, collections, or similar items can affect some models, subject to applicable legal restrictions.
State law can prohibit or restrict particular credit characteristics even when credit-based insurance scoring itself is permitted. That is why a generic nationwide list cannot tell you exactly how your insurer is allowed to use every item on your credit report.
Does Better Credit Always Mean Cheaper Car Insurance?
No. Better credit information may help with an insurer that uses credit-based insurance scoring, but it does not guarantee a lower overall premium.
Auto insurance pricing usually involves multiple variables. A driver with favorable credit information could still pay more because of an expensive vehicle, an at-fault accident, a high-risk garaging area, greater annual mileage, higher coverage limits, or other applicable factors.
Likewise, two insurers can treat similar credit information differently. One company may offer a much more competitive overall premium even if both use some form of credit-based insurance scoring.
Credit Rules Vary Significantly by State
There is no single nationwide rule that determines how insurers may use credit information in auto insurance. States can prohibit credit use, restrict particular practices, require disclosures, or establish rules for how improved or deteriorating credit information may be treated.
A few examples illustrate how different the rules can be:
| State Example | General Treatment | Important Detail |
|---|---|---|
| Massachusetts | Credit information from consumer reporting agencies may not be used for auto insurance underwriting or rating. | Other approved risk factors can still affect premiums. |
| Maryland | Credit history may be considered when initially rating an auto policy, subject to restrictions. | Maryland limits how credit may be used and does not allow a renewal premium increase because the insured’s credit worsened. |
| Nevada | Credit-based insurance scoring is permitted as one criterion, subject to state requirements. | Credit generally must be considered alongside other applicable factors, and disclosure requirements apply. |
These examples should not be used to infer the rule in another state. If credit is affecting a quote or renewal, check your state insurance department’s current guidance or ask the insurer how state law applies to the policy.
How Much Can Credit Change Your Premium?
There is no reliable nationwide percentage that applies to every driver. The effect can differ substantially by insurer, state, scoring model, and the other characteristics used to rate the policy.
For that reason, a statement such as “bad credit increases car insurance by a specific percentage” should not be treated as a universal rule.
The most useful way to understand the effect on your own premium is to ask whether the insurer uses credit information, review any required notice you receive, and compare equivalent quotes from several companies.
A Practical Example
Consider two hypothetical drivers applying for identical coverage from an insurer in a state where credit-based insurance scoring is allowed. These numbers are illustrative only and are not market averages.
Driver A: has a clean driving history and receives a favorable credit-based insurance score under the insurer’s model.
Driver B: has an otherwise similar insurance profile but receives a less favorable credit-based insurance score.
If the insurer’s approved rating plan uses that score, Driver B could receive a higher premium even though the two drivers have similar driving records. The actual difference would depend on the insurer’s model and applicable state rules.
If both drivers requested quotes from a different company, the price difference could change because insurers do not necessarily use the same scoring model or give credit information the same weight.
Can Improving Your Credit Lower Car Insurance Rates?
Potentially. If your insurer uses credit-based insurance scoring and state rules allow updated credit information to benefit you, improvements in your credit history may eventually contribute to a better insurance rate.
There is no guarantee that a change in your consumer credit score will produce a specific insurance discount. Insurance scoring models differ, and other rating factors may change at the same time.
General credit practices that may improve traditional credit information over time include paying bills on time, reducing outstanding balances, and avoiding unnecessary new credit accounts. More importantly for insurance purposes, make sure the underlying credit report is accurate.
Check Your Credit Report for Errors
Because a credit-based insurance score relies on information from your credit history, inaccurate information can potentially affect an insurance decision.
Review your credit reports and dispute information that is inaccurate or incomplete. Examples might include an account that does not belong to you, an incorrectly reported late payment, or an account that should have been updated after a balance was paid.
After correcting an error: contact your insurer and ask whether the corrected information can be used to recalculate your insurance score or re-rate the policy. Your rights and the insurer’s obligations can depend on state law.
What if Credit Causes You to Get a Worse Insurance Rate?
Federal Fair Credit Reporting Act protections can apply when information in a consumer report contributes to an adverse insurance decision.
An adverse action can include situations such as being denied insurance or being charged more when information from a consumer report contributed to the decision.
The required notice generally identifies the consumer reporting agency that supplied the information and explains rights related to obtaining the report and disputing inaccurate information.
Do not ignore an adverse-action notice. It can help you identify which consumer reporting agency supplied the information so you can review the report and dispute errors if necessary.
Can Shopping for Car Insurance Hurt Your Credit?
Insurance-related credit rules should not be assumed to work exactly like applying for a loan. State laws can restrict how credit inquiries related to insurance shopping are treated.
For example, Nevada specifically restricts insurers from negatively using inquiries generated when a consumer shops for insurance coverage. Other states may apply different rules.
If this is a concern, ask the insurer what type of credit information it obtains during the quote process and check your state’s insurance rules rather than assuming an insurance quote works like a new credit-card application.
How to Lower Your Rate if Credit Is Hurting Your Premium
Improving your credit history may help over time, but it is not the only strategy available. You can also look for immediate ways to reduce your insurance cost without waiting for your credit profile to change.
- Compare several insurers: Different companies may treat the same credit and driving profile differently.
- Check your reports: Correct inaccurate credit information that could be affecting an insurance score.
- Ask about re-scoring: Find out whether improved credit can trigger a new insurance score under your state’s rules.
- Review discounts: Multi-policy, low-mileage, safe-driver, vehicle-safety, and other discounts may offset part of the cost.
- Compare deductibles carefully: A higher collision or comprehensive deductible can reduce premiums but increases what you may pay after a covered claim.
Frequently Asked Questions
The Bottom Line
Your credit history can affect car insurance rates in many parts of the United States, but the process is more complicated than an insurer simply looking at your ordinary credit score.
Where permitted, insurers may use a credit-based insurance score along with driving history, vehicle information, coverage choices, and other approved rating factors. State laws can significantly restrict how that information is used, so the answer can change depending on where you live.
If credit appears to be increasing your premium, review your credit reports for errors, ask the insurer how credit affects its rating process, understand your state protections, and compare equivalent quotes from other insurers.
