How Your Credit Score Affects Car Insurance Rates and What You Can Do About It

Most people have no idea that their credit history plays a major role in determining their car insurance premium. It seems like an odd connection at first glance: what does your payment history on a credit card have to do with how safely you drive? But insurance companies have spent decades analyzing data, and they have found a strong statistical correlation between credit behavior and the likelihood of filing insurance claims. Drivers with poor credit file claims more frequently than drivers with excellent credit, and that pattern holds true even when you control for other factors like age, driving record, and vehicle type. Whether this correlation reflects a causal relationship or simply captures broader patterns related to financial stress is a matter of ongoing debate, but the practical reality is that your credit score can raise or lower your premium by hundreds of dollars per year.

The score that insurers use is not exactly the same as the FICO score your bank looks at when you apply for a mortgage or credit card. It is called a credit based insurance score, and it weighs certain factors differently. The most widely used model is the LexisNexis Attract score, though some companies use models from FICO, TransUnion, or their own proprietary systems. These scores pull data from your credit reports but emphasize the factors that are most predictive of insurance risk rather than lending risk.

Payment history is the single largest component of your credit based insurance score, accounting for roughly 40 percent of the total. This includes whether you pay your bills on time, how many late payments you have, and how recently those late payments occurred. Outstanding debt and credit utilization make up about 30 percent. The length of your credit history contributes around 15 percent, and the mix of credit types and recent credit inquiries account for the remaining 15 percent. Notably, your income, employment status, and bank account balances are not included in the calculation, because credit reports do not contain that information.

The impact of credit on insurance pricing is larger than most people expect. According to a study by the Consumer Federation of America, drivers with poor credit pay an average of 60 to 115 percent more for car insurance than drivers with excellent credit, even when they have identical driving records. In dollar terms, that can mean a difference of $1,000 to $2,500 per year for the same coverage. A driver with a clean record and a 580 credit score might pay $2,800 per year for a policy that would cost a driver with a clean record and a 780 credit score only $1,200. That is a $1,600 annual penalty for having poor credit, and over a five year period, it adds up to $8,000 in extra premiums.

The magnitude of the credit impact varies by insurer and by state. Some companies weigh credit more heavily than others in their pricing models, which is one reason why shopping around is so important for drivers with less than perfect credit. A company that places heavy emphasis on credit will charge you significantly more, while a company that weighs driving record more heavily may offer a much better rate for the same coverage. This variation means that the cheapest insurer for someone with great credit is often not the cheapest insurer for someone with poor credit.

Not every state allows insurers to use credit in their pricing. California, Hawaii, Massachusetts, and Michigan have banned or severely restricted the use of credit based insurance scores for auto insurance. If you live in one of these states, your credit will not affect your car insurance premium. Maryland and Oregon have also placed limitations on how credit can be used, requiring insurers to weigh it less heavily than they might in other states.

In the remaining states, insurers are generally allowed to use credit as a rating factor, but they must follow certain rules. Most states prohibit insurers from using credit score alone to deny coverage. Many require that insurers offer an extraordinary life circumstances exception, which allows you to request that your credit not be used if you can show that a recent event like a divorce, job loss, serious illness, or death of a family member caused a temporary decline in your credit. This exception is underutilized because most people do not know it exists, so if you have experienced a qualifying hardship, it is worth asking your insurer about it.

Because payment history is the most heavily weighted factor, the single most impactful thing you can do is make every payment on time going forward. Set up autopay for at least the minimum payment on all of your accounts to eliminate the risk of missed payments due to forgetfulness. A single 30 day late payment can drop your insurance score significantly, and it takes two to three years of on time payments to fully recover from that damage.

Reducing your credit utilization is the second most effective step. Credit utilization is the percentage of your available credit that you are currently using, and lower is better. If you have a credit card with a $5,000 limit and a $4,000 balance, your utilization on that card is 80 percent, which is considered very high. Aim to keep your overall utilization below 30 percent, and below 10 percent if possible. You can achieve this by paying down existing balances, requesting credit limit increases on your existing cards, or both. Paying down balances has a relatively quick impact on your score because credit utilization is recalculated each time your card issuer reports to the credit bureaus, which is typically once per month.

Avoid opening multiple new credit accounts in a short period of time, because each application generates a hard inquiry on your credit report and reduces the average age of your accounts. Both of these factors can lower your insurance score. If you need to open a new account, try to space applications at least six months apart. On the other hand, do not close old credit accounts unless they carry an annual fee you cannot justify. Closing an old account shortens your average account age and reduces your total available credit, both of which can hurt your score.

You cannot access your exact credit based insurance score the way you can check your FICO score, because insurance scoring models are proprietary. However, your regular credit score is a reasonable proxy. If your FICO score is improving, your insurance score is very likely improving as well because they draw from the same underlying data. Check your credit reports from all three bureaus at least once per year through AnnualCreditReport.com, and dispute any errors you find. Errors on credit reports are surprisingly common, and correcting them can boost your score quickly.

When you notice a meaningful improvement in your credit score, contact your insurer and ask them to re-run your credit based insurance score. Some companies do this automatically at renewal, but others use the score they pulled when you first purchased your policy and do not update it unless you ask. If your credit has improved significantly, getting a fresh score could lower your premium at your next renewal without requiring you to switch companies. And if your current insurer will not re-score you, use that improved credit to shop around and get new quotes, because other companies will pull a fresh score as part of the quoting process.
