Many drivers and homeowners are surprised to learn that a clean driving record or claim-free history may not be the only information affecting an insurance quote. Insurers can use several rating factors, and in many states one of those factors is a credit-based insurance score.
The National Association of Insurance Commissioners (NAIC) says these scores are designed to predict the likelihood of future insurance losses, not whether a consumer will repay a loan. The scoring model may rely partly or entirely on credit-report information, but it can weigh that information differently from a traditional lending score.
Insurance score vs. regular credit score
| Feature | Credit-based insurance score | Traditional lending credit score |
|---|---|---|
| Main purpose | Estimate insurance loss/claim risk | Estimate likelihood of repaying borrowed money |
| Data source | Credit-report information, weighted for insurance risk | Credit-report information, weighted for lending risk |
| Typical use | Auto/home underwriting or rating where allowed | Loans, cards and other credit decisions |
| Is it the only insurance factor? | Usually no; state law often limits sole use | Not applicable to insurance pricing by itself |
What information can influence an insurance score?
Scoring formulas are proprietary and differ by model. They can consider credit-report characteristics such as payment history, outstanding balances, length of credit history, account mix and recent credit activity. The exact weights are not necessarily the same as the score shown in a consumer banking app.
Insurance pricing can also use many non-credit factors, including claims history, driving record, vehicle characteristics, location, property characteristics, coverage limits and deductibles. An insurance score should be understood as one input in a larger rating system where state law permits it.
State law matters
Insurance is primarily regulated at the state level, and states do not all permit the same use of credit information. The NAIC notes that most states place limits on using credit-based insurance scores as the sole reason to increase a rate or deny, cancel or refuse to renew a policy, while some states impose additional restrictions or prohibit particular uses.
Because these rules can change, do not rely on a generic national list. Check the insurance department in the state where the policy is issued if you want to know whether an insurer can use credit information for your auto or homeowners policy.
What is an adverse-action notice?
If a business denies insurance or offers less favorable terms because of information in a consumer report, federal law can require an adverse-action notice. The Federal Trade Commission explains that the notice must identify the consumer reporting company that supplied the information, and it can include credit-score information when a score was a factor.
This is important because the reporting agency did not make the insurer’s decision. The notice gives you a path to review the underlying report and dispute inaccurate information.
What to do if your insurance price changed because of credit information
- Read the adverse-action or credit notice. Identify the consumer reporting agency and the factors disclosed.
- Get your reports. Review the credit report or specialty consumer report that was used.
- Dispute factual errors. Incorrect balances, accounts that are not yours or outdated information can affect scoring.
- Ask whether extraordinary-life-event rules apply. Some state laws or insurer programs allow reconsideration after qualifying circumstances.
- Shop comparable coverage. Insurers can use different scoring models and rating weights, so results can vary even with the same credit history.
- Do not reduce essential coverage just to offset a price increase. Compare deductibles and limits carefully before making changes.
Will checking your own credit report hurt an insurance score?
Requesting your own consumer report is not the same as applying for new credit. Reviewing reports is a good risk-management step before shopping for insurance because it gives you time to dispute errors rather than discovering them after a quote or renewal.
Can you improve a credit-based insurance score?
There is no universal insurance-score formula, so no single action guarantees a specific premium change. Maintaining accurate credit reports and sound credit habits — such as paying obligations on time and managing balances — can support the underlying credit information used by many models. Insurance rates can still change for reasons unrelated to credit.
Frequently asked questions
Is my FICO score the same as my insurance score?
No. Both can use credit-report information, but they are designed for different predictions and can apply different formulas.
Can an insurer cancel my policy only because my insurance score changed?
State law controls how credit information may be used, and many states restrict using it as the sole basis for an adverse insurance decision. Check your state insurance department for the rule that applies to your policy.
Can I dispute an insurance score?
You can dispute inaccurate information in the underlying consumer report. The insurer or score provider may also have a process for questions about the score or its use.
