Yes, your credit score directly affects your car insurance rate in most states
Insurance companies use your credit score to set your premium — often as much as they use your driving record. A lower credit score typically means a higher rate, sometimes 50% to 100% more than what someone with excellent credit pays for the same coverage. This practice is legal in 48 states. California, Hawaii, and Massachusetts prohibit it entirely. Insurance companies call this credit-based insurance scoring, and it is separate from your credit score itself — they build their own score using credit data.
The reason insurers do this is statistical: they have found that people with lower credit scores file more claims overall, whether for accidents, theft, or other losses. Whether that correlation reflects actual risk or other factors is debated, but the practice is established and widespread. If your credit score is low, you will see the effect immediately in your quote.
Key Takeaways
- Insurance companies in 48 states legally use credit information to set car insurance rates, and a low credit score can double your premium.
- California, Hawaii, and Massachusetts ban credit-based insurance scoring entirely, so your credit score does not affect your rate there.
- Improving your credit score over time will lower your insurance rate, though the effect is not immediate — you may need to shop around or ask your insurer to re-quote you.
- Some insurers weight credit less heavily than others, so comparing quotes from multiple companies can save you money even with the same credit score.
- Paying bills on time, reducing debt, and disputing errors on your credit report are the main ways to raise your score and lower your insurance cost.
Which states ban credit scoring for insurance
California, Hawaii, and Massachusetts do not allow insurers to use credit information when setting car insurance rates. If you live in one of these states, your credit score has no effect on your premium, regardless of how low it is.
A few other states restrict the practice but do not ban it outright. Maryland requires insurers to offer a discount to people with no credit history. South Carolina and Utah limit how much weight insurers can give to credit. If you live in one of these states, credit still affects your rate, but the impact is smaller than in states with no restrictions.
How insurance companies build a credit-based score
Insurance companies do not use your actual credit score from Equifax, Experian, or TransUnion. Instead, they build their own score using similar data: payment history, outstanding debt, length of credit history, and how often you have applied for new credit. The exact formula varies by insurer and is proprietary — they do not publish it.
This score is different from your FICO score or VantageScore in important ways. An insurer might weight payment history more heavily than a credit bureau does, or ignore certain types of debt entirely. A bankruptcy or missed payment that devastates your credit score might have less impact on your insurance score, or vice versa. You cannot see your insurance score the way you can see your credit score, and you cannot dispute it through the credit bureaus.
How much your rate increases with a low credit score
The increase varies widely by insurer and state. Some companies raise rates by 25% for a lower credit score; others raise them by 75% or more. A person with poor credit might pay $1,500 a year while someone with excellent credit pays $800 for identical coverage from the same company.
The effect also depends on your state's regulations. States that allow credit scoring but regulate it — like Maryland and South Carolina — typically see smaller rate differences than states with no restrictions. If you live in a state with no limits, shopping around is especially important, because different insurers weight credit differently.
What you can do to improve your insurance rate
The most direct route is to improve your actual credit score. Pay all bills on time, even if it is just the minimum. Reduce the total amount you owe, especially on credit cards — keeping balances below 30% of your credit limit helps more than paying them off entirely. Dispute any errors on your credit report through the credit bureaus (Equifax, Experian, or TransUnion offer free reports at annualcreditreport.com).
These changes take time. Your credit score typically improves over months, not weeks. Once your score rises, your insurance rate will not drop automatically — you will need to ask your insurer for a new quote or shop around to other companies. Some insurers re-quote annually; others only when you renew your policy. If your credit has improved significantly, switching insurers can save you hundreds of dollars.
In the meantime, compare quotes from multiple insurers. Even with the same credit score, different companies charge different rates because they weight credit differently. Getting quotes from at least three insurers takes 15 minutes and can reveal savings of $300 or more per year.
What happens if you have no credit history
If you have never borrowed money or opened a credit card, you have no credit score. Some insurers treat no credit as neutral — they do not penalize you. Others treat it as a risk factor and charge more. A few offer discounts for people with no credit history, particularly in states like Maryland that require it.
If you have no credit history, get quotes from several insurers and ask directly how they handle applicants with no credit. You may find that one company charges significantly less than others. Building credit takes time, but opening a credit card and using it responsibly (paying the full balance monthly or keeping the balance low) will establish a history and eventually lower your insurance rate.
How to find your insurance score
You cannot see your insurance score the way you see your credit score. Insurance companies do not share it with you or with credit bureaus. However, you can request it. Under the Fair Credit Reporting Act, you have the right to know what information an insurer used to make a decision about your rate.
Call your insurance company and ask for a copy of the consumer report they used to set your rate. They must provide it within a reasonable time, usually 30 days. The report will show the data they pulled — payment history, debt levels, and so on — but not the final score they calculated. If you find errors in that data, you can dispute them with the credit bureau that supplied the information.
Frequently Asked Questions
Will my insurance rate go down if I pay off my credit card debt?
Eventually, yes — but not immediately. Your credit score improves over time as you pay down debt, and your insurance rate will reflect that improvement only when you renew your policy or get a new quote. Some insurers re-quote automatically; others only at renewal. If your credit has improved significantly, shopping around to other insurers may save you money faster than waiting for your current insurer to re-quote.
Can I dispute my insurance score if I think it is wrong?
You cannot dispute the insurance score itself, because insurers do not share the formula. However, if the underlying credit data is wrong, you can dispute it with the credit bureau (Equifax, Experian, or TransUnion). Request your consumer report from your insurer first to see what data they used, then dispute any errors with the bureau that supplied it.
Do all insurance companies weight credit the same way?
No. Some insurers weight credit heavily; others barely use it. This is why comparing quotes from multiple companies matters — you might find one that charges significantly less despite your credit score. Getting quotes from at least three insurers takes 15 minutes and often reveals savings of hundreds of dollars per year.
If I live in California, Hawaii, or Massachusetts, does credit affect my rate at all?
No. These three states ban credit-based insurance scoring entirely. Your credit score has no effect on your car insurance rate, no matter how low it is. If you move to another state, your rate may change because your new state allows credit scoring.
How long does it take for a better credit score to lower my insurance rate?
Your credit score typically improves over months as you pay bills on time and reduce debt. Your insurance rate will not drop automatically — you need to ask for a new quote or shop around. Some insurers re-quote annually; others only at renewal. If your credit has improved significantly, switching to a different insurer often saves more money than waiting for your current one to re-quote.
