Most Arizona drivers know that tickets and accidents raise car insurance rates. Fewer realize that something in your credit file can move the price just as much. Insurers use a credit-based insurance score to estimate how likely a policyholder is to file a claim, and that score can change both whether you are offered a policy and what you pay for it.
Riseson Insurance is an independent Arizona broker based in Tempe, and credit questions come up on a lot of our quote calls. This guide explains how credit affects car insurance rates in Arizona, what insurers are not allowed to use, and what you can do if your score is dragging your premium up.
What a credit-based insurance score actually is
A credit-based insurance score is not the same number you see on a credit card app. It is built from your credit report by a scoring vendor, and insurers use it to decide whether to issue or renew a policy and how much to charge. Some carriers look at the full credit report instead of a single score (difi.az.gov).
The Arizona Department of Insurance and Financial Institutions lists the kinds of information carriers weigh, including payment history, how late payments were, the length of your credit history, recent credit inquiries, the number of open credit lines, new installment accounts, and how much of your available credit you are using. Each insurer builds its own model, so the same credit file can produce different prices at different companies.
How much credit can change your car insurance rate
The gap can be large. NerdWallet reports that drivers with poor credit pay about $3,954 a year for full coverage nationally, compared with $2,361 for drivers with good credit, a difference of roughly $1,593 (nerdwallet.com). On minimum coverage the same comparison is about $1,030 versus $648. Averaged across coverage levels, that works out to roughly 67 percent more for poor credit.
Those are national figures, not Arizona quotes, and your own result depends on your driving record, vehicle, ZIP code, and carrier. The takeaway for Arizona drivers is that credit is one of the bigger levers in the rate, and it is one you can sometimes improve. Our guide to
what drives your Arizona car insurance premium shows where credit sits next to the other rating factors.
What Arizona insurers cannot use against you
Arizona sets limits on how credit information can be used. According to DIFI, insurers may not base a decision on the absence of a credit history, on medical collection accounts, on bankruptcies or lien satisfactions more than seven years old, or on your total available line of credit. Scores derived from income, gender, address, ZIP code, ethnic group, religion, marital status, or nationality are also prohibited (difi.az.gov).
That last point matters for people who are new to credit or new to the country. A thin file should not, by itself, count against you unless the insurer can justify it actuarially or treats you as having neutral credit. A small number of states, including California, Hawaii, and Massachusetts, do not allow credit to be used in car insurance rating at all, but Arizona is not one of them (nerdwallet.com).
Your rights when credit raises your rate
If an insurer takes adverse action based on credit, it must tell you. Adverse action includes denying or ending coverage, placing you in a non-standard tier, charging a higher rate, or removing a discount. The notice must give the specific reason, name the credit report source, and explain how to get a copy (difi.az.gov).
You can pull a free report from each credit bureau every year and dispute errors. Once an error is corrected, the insurer must reconsider its decision if you ask. Carriers may also rescore you during the policy term, and you can generally request a fresh score at least once a year, so it is worth asking at renewal after your credit improves.
Practical ways to lower the credit effect on your premium
Start with the factors you control. Pay every bill on time, since payment history carries the most weight in most models. Keep card balances low compared with your limits, avoid opening several new accounts at once, and leave old accounts open to protect the length of your history.
Next, check your reports for mistakes and dispute them. Then shop the policy. Because every carrier weighs credit differently, a driver who is expensive at one company can be priced much better at another. That is the clearest advantage of working with an independent broker, and it pairs well with bundling. Our guide on
how much you save bundling home and auto insurance in Arizona walks through that side of the savings.
Frequently asked questions
Does credit affect car insurance rates in Arizona? Yes. Arizona allows insurers to use credit-based insurance scores for underwriting and rating, within limits set by the state. Carriers weigh factors such as payment history, length of credit history, and credit usage, and each company uses its own model.
How much more do drivers with poor credit pay for car insurance? NerdWallet reports that poor-credit drivers pay about $3,954 a year for full coverage nationally versus $2,361 for good credit, roughly 67 percent more across coverage levels. Arizona rates vary by carrier, driving record, and ZIP code, so a quote is the only way to see your own number.
Can my insurer raise my rate because I have no credit history? Generally not on that basis alone. Arizona bars decisions based on the absence of a credit history unless the insurer can justify it actuarially or treats you as having neutral credit information, according to DIFI.
What can I do if I think my credit score is hurting my car insurance rate? Request your free credit reports, dispute any errors, and ask your insurer to reconsider once they are fixed. You can also ask for a rescore at renewal and compare quotes from several carriers, since each weighs credit differently.
