How Your Credit Score Affects Your Car Insurance Rates (And How to Fix It)

You’ve got a clean driving record. No accidents. No tickets. No DUIs. So why is your car insurance bill still sky-high?

Here’s something a lot of people don’t find out until it’s too late: your credit score can move your car insurance premium just as much as, sometimes more than, your driving history. According to Bankrate’s 2025 True Cost of Auto Insurance report, drivers with poor credit pay an average of $2,006 more per year for full coverage than drivers with good credit. In some states, that gap is even wider, in South Dakota, poor credit more than doubles your premium, and in San Antonio, TX, the gap exceeds 140%. In certain cases, the credit penalty is actually larger than the penalty for a prior DUI.

That’s a lot of money leaving your wallet every year for something that has nothing to do with how you drive. The good news? Credit can be managed and improved over time. Here’s exactly what you need to know—why insurers look at your credit, what they’re actually measuring, what it could be costing you, and the concrete steps to help bring that number up and your premium down.

Why Do Insurance Companies Look at Your Credit?

It feels counterintuitive. What does paying your credit card bill on time have to do with how you drive?

Insurers have a data-based answer. Decades of actuarial research (including a landmark 2007 Federal Trade Commission study), found that there’s a measurable correlation between how people manage their finances and how often they file insurance claims. People with lower credit scores tend to file claims more frequently, and those claims tend to cost more on average. The theory is that individuals who manage their finances responsibly also tend to maintain their vehicles and exercise more caution while driving.

A few other things worth knowing here:

• Widespread Industry Practice: Roughly 95% of auto insurers use some form of credit information when setting premiums in states where the practice is legally permitted (Source: FICO).
• State Restrictions: California, Hawaii, and Massachusetts ban this practice outright, while Michigan has significant restrictions. If you reside in one of those states, your credit score won't touch your auto insurance rate. Everywhere else, it is considered fair game (Source: NAIC).
• Specialized Scoring Models: Insurers don’t use your standard FICO score. Instead, they utilize a specialized credit-based insurance score. While built from the same underlying credit report data, it is weighted differently. A standard credit score predicts your likelihood to repay a loan, whereas a credit-based insurance score is specifically designed to predict how likely you are to file an insurance claim. The score ranges differ as well—LexisNexis’s Attract score runs from 200 to 997, and FICO’s insurance score ranges from 100 to 900, compared to the traditional 300–850 credit score spectrum.

What Are the 5 Factors That Affect Your Credit-Based Insurance Score?

Here’s what each factor means in plain English, and how you can address it:

• Payment history (40%): The single biggest lever. A single missed payment can negatively impact your score, while a long track record of on-time payments establishes reliability. Setting up autopay for at least the minimum balance due on your accounts helps ensure you never miss a deadline.
• Outstanding debt / utilization (30%): This represents your credit utilization ratio, the amount of available credit you are actively using. For instance, if your card has a $5,000 limit and you carry a $4,000 balance, that equals 80% utilization, which can severely weigh down your score. Aiming to keep utilization below 30% is standard practice, though staying under 10% is even better.
• Length of credit history (15%): This factors in the age of your oldest accounts, your newest accounts, and the average age across your entire profile. This is why closing old, unused cards can backfire; keeping them open preserves the account age in your favor.
• New credit inquiries (10%): Applying for new credit triggers a hard inquiry. Multiple hard inquiries within a short window can signal financial stress and temporarily ding your score. It is generally best to avoid applying for new lines of credit right before your insurance policy renews.
• Credit mix (5%): Maintaining a diverse portfolio of installment loans (such as an auto or personal loan) and revolving credit (such as credit cards) demonstrates an ability to manage different types of credit responsibly.

What Is a Poor Credit Score Costing You on Car Insurance?

A $2,387 annual difference stands between excellent and poor credit—for the exact same vehicle, driver, and coverage options. Furthermore, in 17 states and Washington D.C., drivers categorized with poor credit pay at least double the rate of drivers with good credit for full coverage policies (Source: Bankrate 2025).

Beyond auto insurance, improving your credit health positive influences multiple areas of your financial life simultaneously. Working on your credit isn't just about qualifying for a loan down the road; it provides ongoing financial benefits, including whenever your insurance policy comes up for renewal.

How Do You Fix Your Credit Score? 5 Action Steps

The most effective way to address your credit score is to build a consistent record of paying bills on time, lowering outstanding credit card balances, preserving older accounts, adding positive credit tradelines, and disputing credit report inaccuracies.

Here is how to approach each step:

Step 1: Pay on time, every single time

Payment history accounts for roughly 40% of your credit-based insurance score, making it your highest-impact focus area. If you have missed payments in the past, work to bring the accounts current, stay consistent moving forward, and allow positive history to build over time. Setting up automated minimum payments across your accounts provides a reliable safety net.

Step 2: Aim to bring utilization below 30%

Because credit utilization is recalculated monthly when your statement closes, lowering your balances can influence your credit file relatively quickly. Paying down card balances—even partially—prior to the statement closing date ensures that lower utilization is reported to the bureaus, which frequently reflects positively on your profile within 30 to 60 days. Keep individual and total card usage under 30%, or under 10% for optimal results.

Step 3: Avoid closing old accounts

It can be tempting to close out old cards you no longer actively use, but doing so can reduce your average credit age and lower your total available credit, which inadvertently spikes your utilization ratio. If a card charges no annual fee, keeping it open, running a small recurring charge on it, and paying it off immediately helps protect your established history.

Step 4: Add a positive tradeline

If you have a thin credit file, adding a positive, regularly reporting account can be highly beneficial. Financial technology tools such as Ava's Credit Builder Mastercard and Save & Build Credit Account are designed to help. Ava reports monthly payment activity to all three major credit bureaus (Equifax, Experian, and TransUnion) with no hard credit check required during application. Establishing a consistent history of on-time payments through credit-building tools reinforces both your insurance score and your broader credit profile.

Step 5: Dispute errors on your credit report

A 2021 study by Consumer Reports revealed that more than a third of consumers surveyed discovered errors on their credit reports—ranging from outdated accounts to incorrect late payment marks and duplicates. You can access your free credit reports from each bureau via annualcreditreport.com. Review all three documents thoroughly and submit disputes directly with the respective bureau to correct any inaccuracies. While resolution typically takes 30 to 45 days, removing an inaccurate negative mark can noticeably benefit your score.

How Do Credit Rebuilding and Reporting Apps Compare?

If your primary goal is to lower your car insurance premiums over time, the most useful credit-rebuilding applications are those that report to all three major bureaus, do not require a hard credit check, and assist you in establishing steady payment habits. Ava offers an all-in-one suite for this path, alongside alternatives like Self, Experian Boost, and Credit Karma Money.

Here is a closer look at how these platforms operate:

• Ava (Credit Builder Mastercard + Save & Build Credit Account):⁸ Ava is structured explicitly to assist users looking to establish or rebuild credit. The Credit Builder Mastercard is a virtual card that requires no hard credit check and charges no interest on builder products. The Save & Build Credit Account operates as a 12-month secured savings loan, letting you save funds while building a documented payment history. To receive the full amount, members must complete the full payment schedule; applicable origination fees are excluded, and early program exits receive only the exact amount they successfully contributed. Both products report to Experian, Equifax, and TransUnion monthly, ensuring on-time payments count toward your standard FICO and insurance scores. Ava also provides rent and utility payment reporting, adding additional positive monthly touchpoints to your credit files.
• Self (Credit Builder Loan): Self provides a credit-builder loan structured like a savings plan. You commit to fixed monthly payments (starting around $25/month), which Self reports to all three bureaus, and the accumulated funds are unlocked at the end of the term. While it is a structured installment option, it does accumulate interest and administrative fees, which reduces the total amount returned to you at completion. Self also offers an optional secured credit card after meeting initial account milestones.
• Experian Boost: This free feature scans your connected bank account transactions for recurring on-time payments—such as utilities, phone bills, rent, and streaming services—and adds them directly to your Experian credit file, yielding an average reported score increase of 13 points. The primary limitation is that it only affects your Experian credit report, leaving Equifax and TransUnion unimpacted. Because auto insurers frequently pull data from all three major bureaus, it functions best as a supplement rather than a standalone credit-building strategy.
• Credit Karma Money (Credit Builder): This option utilizes a secured line of credit layout where payments are saved into a locked account and reported to all three major bureaus. The service is free, earns interest on your deposits, and links directly with Credit Karma's monitoring tools. However, it is primarily focused on passive saving and credit building, meaning it does not directly address existing high utilization on external accounts or credit report errors.

The Takeaway: For consumers starting from scratch or actively recovering their credit, Ava’s combined approach of a virtual credit card, a savings-backed account, and integrated rent/utility reporting covers extensive credit-building ground without requiring a hard credit check or charging interest on builder features.

How Long Until a Better Credit Score Shows Up in Your Insurance Rate?

It is important to manage expectations: your auto insurance premium will not suddenly drop the week after your credit score improves. Here is the realistic timeline you can expect:

1. Credit Bureau Reporting (30–60 Days): Creditors generally update and report account balances and payment statuses once per month. If you clear a card balance today, it can take 30 to 60 days for that change to register across your credit files.
2. Insurance Score Updates (Every 6–12 Months): Most auto insurance companies pull a refreshed credit-based insurance score exclusively at your semi-annual or annual policy renewal. Consequently, mid-term credit improvements usually will not alter your current active premium.
3. Mid-Policy Re-Rating (By Request Only): A handful of insurance providers may allow a mid-term policy re-rate if your credit score has experienced a substantial upward shift (typically 50+ points). It is worth calling your agent to inquire, but it should not be assumed as a guarantee.

The most reliable approach is to focus on steady credit improvement well ahead of time so that the progress naturally reflects in your upcoming renewal quotes. While individual results depend entirely on personal financial profiles, dedication to credit health can yield notable benefits. According to national data from Bankrate's 2025 report, moving up a single credit tier from "poor" to "average" can save drivers an average of over $1,700 annually on auto premiums.

The Bottom Line

Your credit score is a significant financial lever that quietly impacts what you pay for car insurance every six months. The math remains straightforward: improved credit health can unlock lower premiums, better financing terms, and reduced out-of-pocket expenses.

The core habits require consistency: pay your bills on time , reduce your outstanding credit utilization , keep your oldest accounts active , establish positive history , and check your reports for errors. If you are looking for a clear path to build or rebuild your credit profile, Ava’s Credit Builder Mastercard and Save & Build Credit Account provide a streamlined, three-bureau reporting mechanism designed to ensure your daily financial responsibility works in your favor.

Disclaimers: Results vary by individual. Credit score improvement and any associated savings are not guaranteed and depend on your specific financial situation, credit history, insurer, state laws, and other factors. Potential savings ranges represent illustrative projections across multiple financial products and do not guarantee specific outcomes.
