Credit Score Car Insurance Rates: How Your Score Affects Premiums

Most people know that a good credit score helps them qualify for better loan terms, but far fewer realize the direct connection between credit score car insurance rates. In most states, auto insurance companies use a credit-based insurance score as one of the key factors when calculating your premium. If your credit has taken a hit, you could be paying hundreds of dollars more each year for the same coverage as someone with excellent credit.

In this guide, we will explain exactly how insurers use your credit information, why this practice is legal, how much it can affect your premium, and what steps you can take to improve both your credit and your insurance costs.

What Is a Credit-Based Insurance Score?

A credit-based insurance score is not the same as your regular FICO score or VantageScore, though it is derived from similar data in your credit report. Insurance companies use specialized scoring models—often developed by FICO or LexisNexis—that predict the likelihood that you will file a claim.

While your standard credit score predicts whether you will repay a debt, a credit-based insurance score predicts your risk as an insurance customer. Insurers have found a strong statistical correlation between how people manage their finances and how likely they are to file claims. This is why credit score car insurance rates are so closely linked.

Why Do Car Insurance Companies Check Your Credit?

Auto insurers are in the business of assessing risk. When you apply for a policy or request a quote, they evaluate dozens of factors to estimate how likely you are to file a claim and how expensive that claim might be. These factors include your driving record, age, location, vehicle type, and—critically—your credit-based insurance score.

Research from insurance industry groups and independent studies has consistently shown that drivers with lower credit-based insurance scores tend to file more claims and higher-cost claims than those with stronger scores. Insurers argue that using credit data helps them price policies more accurately and fairly for all customers.

How Much Does Credit Affect Car Insurance Rates?

The impact of credit on your auto insurance premium can be dramatic. According to multiple industry studies, drivers with poor credit can pay 50% to 100% more for car insurance than drivers with excellent credit, depending on the state and insurer.

Here is a general breakdown of how credit tiers affect premiums:

• Excellent credit (750+): You will typically receive the lowest available rates. Insurers view you as a low-risk customer.
• Good credit (700-749): Your rates will be competitive, though slightly higher than the best tier.
• Fair credit (650-699): You may see a noticeable increase in premiums compared to those with excellent credit.
• Poor credit (below 650): Expect significantly higher premiums. In some states, the difference can be thousands of dollars per year.

For example, a driver with excellent credit might pay $1,400 per year for full coverage, while a driver with poor credit could pay $2,800 or more for the same policy from the same insurer. That is a substantial difference that adds up over time.

Which States Restrict Credit-Based Insurance Scores?

Not all states allow insurers to use credit information when setting rates. Several states have banned or limited this practice:

• California, Hawaii, Massachusetts, and Michigan prohibit the use of credit scores in auto insurance rating.
• Oregon and Utah have restrictions on how credit data can be used.
• Other states have introduced legislation to limit or study the practice.

If you live in a state where credit-based scoring is allowed, improving your credit is one of the most effective ways to lower your car insurance premium. Check with your state’s department of insurance to understand the rules in your area.

What Credit Factors Do Insurers Look At?

While each insurer uses its own proprietary model, most credit-based insurance scores consider the following factors from your credit report:

• Payment history: Whether you pay your bills on time. This is typically the most heavily weighted factor.
• Outstanding debt: How much you owe relative to your credit limits.
• Length of credit history: How long your accounts have been open.
• New credit applications: Recent hard inquiries and newly opened accounts.
• Credit mix: The variety of credit accounts you hold (credit cards, loans, mortgages).

Notably, insurers do not consider your income, race, gender, or marital status when calculating your credit-based insurance score. The score is purely based on the information in your credit file.

How to Improve Your Credit and Lower Your Insurance Rates

If your credit score is dragging down your car insurance rates, the good news is that you can take concrete steps to improve the situation. Here is what works:

1. Pay All Bills on Time

Payment history accounts for roughly 35% of your FICO score. Set up automatic payments or calendar reminders to ensure you never miss a due date. Even one late payment can cause a significant drop in your score.

2. Reduce Your Credit Utilization

Your credit utilization ratio—the amount of credit you are using compared to your total limits—should stay below 30%, and ideally under 10%. Pay down existing balances and avoid maxing out your cards. Learn more about managing your credit utilization ratio effectively.

3. Check Your Credit Report for Errors

Errors on your credit report are more common than you might think. Incorrect accounts, wrong balances, or outdated negative marks can all drag down your score. Request your free reports from AnnualCreditReport.com and dispute any inaccuracies you find. Our guide on how to find credit report errors can help you get started.

4. Avoid Opening Unnecessary New Accounts

Each new credit application generates a hard inquiry, which can temporarily lower your score. Only apply for credit when you genuinely need it.

5. Keep Old Accounts Open

The length of your credit history matters. If you have an old credit card in good standing, keep it open even if you do not use it regularly. Closing it could shorten your average account age and hurt your score.

6. Shop Around for Insurance

Different insurers weigh credit data differently. If your credit is fair but not excellent, getting quotes from multiple companies can reveal significant price differences. Some insurers place less emphasis on credit than others.

Does Improving Credit Actually Lower Insurance Premiums?

Yes, but the timing depends on your insurer. Most auto insurance companies re-evaluate your credit-based insurance score at each policy renewal, which typically happens every six or twelve months. If your credit has improved since your last renewal, you may see a lower premium at your next renewal period.

Some insurers allow you to request a mid-term review if your credit has improved significantly. Contact your insurance agent or company to ask about their policy on mid-term adjustments.

Other Factors That Affect Car Insurance Rates

While credit is an important factor, it is just one piece of the puzzle. Your car insurance rate is also influenced by:

• Driving record: Accidents, tickets, and DUIs significantly increase premiums.
• Age and experience: Younger and older drivers typically pay more.
• Vehicle type: Cars with high safety ratings and lower repair costs tend to be cheaper to insure.
• Annual mileage: Driving fewer miles generally means lower risk and lower premiums.
• Location: Urban areas with higher traffic density and theft rates often have higher premiums.
• Coverage levels: Higher deductibles and lower coverage limits reduce your premium but increase your out-of-pocket risk.

Understanding how all these factors work together can help you make smarter decisions about both your credit and your insurance coverage.
