How Your Credit Score Affects Car Insurance Rates (And What to Do About It)

What Are Credit-Based Insurance Scores?

Credit-based insurance scores are specialized three-digit numbers, typically ranging from 200 to 997, that insurance companies calculate from your credit report to predict the likelihood you'll file a claim. Unlike traditional FICO credit scores used by lenders, these scores are specifically designed for risk assessment in the insurance industry.

How Insurance Scores Differ from Credit Scores

While both types of scores draw from your credit report, they weight factors differently. The FICO insurance score model breaks down as follows:

• Payment history (40%): Your track record of paying bills on time
• Outstanding debt (30%): Total amount of debt you currently carry
• Length of credit history (15%): How long you've maintained active credit accounts
• New credit inquiries (10%): Recent applications for new credit
• Credit mix (5%): Variety of credit types like cards, mortgages, and loans

Each insurance company generates its own proprietary score, so your rating can vary between insurers. By law, these scores cannot include race, gender, age, income, nationality, religion, disability, or marital status.

Factors That Lower Your Insurance Score

Several behaviors can negatively impact your credit-based insurance score:

• Missing or late payments on credit accounts
• Carrying high balances relative to your credit limits
• Having limited or short credit history
• Filing for bankruptcy or having accounts in collections
• Applying for multiple new credit accounts in a short period

Understanding these factors helps you identify areas for improvement that can lead to lower insurance premiums. If you're comparing quotes, your credit-based score will be one of the key factors that affect car insurance rates you receive.

Why Insurance Companies Use Credit Information

Insurance companies rely on credit-based scores because extensive research demonstrates a strong correlation between credit behavior and insurance claims. This practice has been validated through multiple independent studies and regulatory reviews.

The Statistical Connection

A Federal Trade Commission study confirmed that credit scores are accurate predictors of insurance claims. Research shows drivers with the worst insurance scores are significantly more likely to file claims (and larger claims) compared to those with the best scores. This pattern holds true across both auto and homeowners insurance, giving insurers confidence in the predictive power of these scores.

Industry Perspective

Insurers argue that credit-based scoring allows them to:

• More accurately assess individual risk levels
• Price policies fairly based on statistical data
• Prevent lower-risk customers from subsidizing higher-risk drivers
• Maintain competitive rates by identifying good risks

As of August 2026, proposals to restrict or ban credit-based scoring are actively advancing in several states. Lawmakers in Iowa, New York, Oklahoma, and Pennsylvania have all introduced active 2026 bills targeting the practice, and Congress has opened its own probe of credit-based scoring as premiums climb nationally. However, no new state has enacted a permanent ban beyond the original four (California, Hawaii, Massachusetts, and Michigan). Understanding how insurers view credit risk can help you make strategic decisions about how premiums are calculated.

How Much Credit Affects Your Car Insurance Rates

The impact of your credit score on insurance premiums can be substantial, often resulting in rate differences of 68% to over 118% between credit tiers. This makes credit one of the most significant factors in determining what you'll pay for coverage.

Average Premium Differences by Credit Tier

Multiple 2026 analyses confirm that poor-credit drivers pay significantly more than good-credit drivers for full coverage. Bankrate reports drivers with poor credit pay about 76% more for full coverage than drivers with good credit, roughly $4,644 per year, or $2,006 more than a driver with good credit. Insure.com's analysis found drivers with bad credit pay about 113% more, roughly $2,900 more per year. ValuePenguin's 2026 data shows people with bad credit pay an average of $204 more per month for full coverage than people with good credit. MoneyGeek's analysis shows poor credit costs an average of $320 more a month, adding up to $3,838 a year. NerdWallet's 2026 research puts the gap at roughly $1,581 more per year, and an August 2026 LendingTree study pegs it at 68.2% more, or about $1,553 per year and $4,660 over three years.

Drivers who improve their credit by even one tier can save hundreds of dollars annually. Even moving from poor to average credit typically knocks meaningful dollars off premiums at renewal. For broader context on premium changes, review 15 proven ways to lower car insurance.

Credit as One of Many Rating Factors

While credit significantly impacts rates, it's just one of several factors insurers consider. Your final premium also depends on:

• Driving record and accident history
• Claims history
• Age and years of driving experience
• Location and ZIP code
• Vehicle make, model, and year
• Annual mileage
• Coverage levels and deductibles

Different insurers weight these factors differently. Some emphasize credit more heavily, while others focus more on driving record or vehicle type. This variation is exactly why comparing quotes from multiple companies is so important. Reviewing how premiums are calculated can help you understand how each carrier stacks the factors that affect your rate.

States That Ban or Restrict Credit-Based Insurance Scoring

Not all states permit insurers to use credit information when setting rates. As of August 2026, four states have effectively banned the practice for auto insurance, while several others have placed meaningful restrictions on its use.

States with Complete Bans

California: California's prohibition stems from Proposition 103 and has been in place since 1988, making it one of the most consumer-friendly states for drivers with poor credit. Learn more about the cheapest car insurance in California for drivers in the state.

Hawaii: Auto insurers are banned from using credit in underwriting standards, rating plans, or premium calculations.

Massachusetts: Law forbids use of credit information for setting rates, underwriting new policies, or renewing auto coverage. This protection extends to all drivers regardless of their credit situation.

Michigan: Insurers cannot use credit to deny, cancel, refuse renewal, or determine rates for auto policies. Michigan's ban stems from 2020 no-fault reform legislation and provides comprehensive protection for consumers.

States with Partial Restrictions

Maryland: Insurers can consider credit for initial new policy rates but cannot use it to deny applications, cancel policies, refuse renewals, or increase renewal premiums.

Oregon: Insurers cannot cancel or refuse renewal based on credit but can consider limited credit information for initial underwriting and rating.

Utah: Credit can be used for initial underwriting (not as the sole factor) and only to offer discounts, not surcharges. This approach rewards good credit without penalizing poor credit.

Virginia: New restrictions on credit-based rating are cited with an effective date of July 1, 2026, limiting how insurers can apply credit data at renewal.

In 2026, credit-based scoring is under a fresh round of legislative pushback: lawmakers in Iowa, New York, Oklahoma, and Pennsylvania have active bills that would ban or sharply restrict it, though none have passed yet. A Missouri bill introduced in January 2026 would similarly prohibit credit scores from determining car insurance costs. Understanding why some drivers are denied car insurance can also depend on which state rules apply to you.

How to Improve Your Credit-Based Insurance Score

Improving your credit-based insurance score takes time but can lead to significant savings on your car insurance premiums. The strategies below focus on the factors that matter most to insurance scoring models.

Priority Actions for Score Improvement

Pay All Bills on Time

Payment history accounts for 40% of your insurance score, the single most important factor. Set up automatic payments or reminders to ensure you never miss due dates on credit cards, loans, utilities, and other bills. Even one late payment can stay on your report for up to seven years and drop your score by 50 to 100 points.

Reduce Outstanding Debt

Work to pay down balances, especially on credit cards. Aim to keep your credit utilization below 30% of your available credit limits, ideally under 10%. Prioritize high-interest debt first, but make minimum payments on all accounts to maintain positive payment history.

Maintain Established Credit Accounts

Length of credit history matters. Keep older accounts open and active rather than closing them, as this demonstrates financial stability. Even if you don't use a card regularly, charging a small purchase monthly and paying it off keeps the account contributing positively to your credit history.

Limit New Credit Applications

Each hard inquiry can temporarily lower your score by a few points. Apply for new credit only when necessary and avoid multiple applications in a short timeframe. If you're rate shopping for loans, do it within a 14 to 45 day window when multiple inquiries are typically counted as one.

Monitor and Dispute Errors

Check your credit reports from all three bureaus (Equifax, Experian, TransUnion) at AnnualCreditReport.com. Reports are available weekly for free. Dispute any inaccuracies such as accounts that don't belong to you, incorrect payment statuses, or outdated information.

Important 2026 medical debt update: On July 11, 2025, the U.S. District Court for the Eastern District of Texas vacated the CFPB's rule (Regulation V) that would have prohibited medical debt on credit reports. As a result, medical debt can appear on your credit report again in 2026 and may impact your credit-based insurance score. The three major bureaus still voluntarily exclude paid medical collections, medical collections under $500, and enforce a 12-month waiting period before medical debt in collections can be reported. In October 2025, the CFPB also clarified that the Fair Credit Reporting Act preempts most state laws attempting to restrict medical debt reporting. Check your report to ensure those voluntary removals have been applied. If your rate was set based on this information, you may receive an insurance adverse action notice that entitles you to a free credit report and dispute rights.

Credit-Building Tools

Consider these options to establish or rebuild credit:

• Credit-builder loans: 6-24 month products specifically designed to build credit history
• Secured credit cards: Require a deposit but report to credit bureaus just like traditional cards
• Authorized user status: Being added to a family member's account in good standing
• Experian Boost: Tool that adds rent and utility payments to your Experian credit file
• Rent reporting services: Services that report monthly rent payments to credit bureaus

These tools work best when combined with consistent, positive financial habits.

Getting Affordable Car Insurance with Poor Credit

Even with poor credit, several strategies can help you secure more affordable coverage. The key is combining multiple approaches to offset the higher rates your credit score might trigger.

Shop Multiple Insurers

Since each company calculates insurance scores differently, rates can vary dramatically between carriers. Based on the latest 2026 data, the most competitive national options for poor-credit drivers include USAA (military only), Nationwide, Travelers, GEICO, and Progressive, with regional carriers like Country Financial, Erie, and American Family often beating major carriers where available. Always compare quotes from at least 5 to 7 companies. Drivers with high-risk profiles should also review high-risk car insurance options.

Maximize Discounts to Offset Higher Rates

Use every available discount to counteract credit-related surcharges:

• Bundle auto and home/renters insurance (typically 10-25% savings)
• Take a defensive driving course (5-10% discount)
• Install anti-theft devices (2-5% discount)
• Opt for paperless billing and auto-pay (2-5% discount)
• Maintain continuous coverage without lapses
• Drive fewer miles annually (low-mileage discount)

These discounts can stack, potentially reducing your premium by 30-40% or more. See how common car insurance myths around discounts can cost you money.

Consider Usage-Based Insurance

Some insurers offer telematics programs that track your driving habits through a mobile app or device. Good driving behavior (avoiding hard braking, limiting nighttime driving, and maintaining steady speeds) can earn meaningful discounts regardless of your credit score. Pay-per-mile programs base rates primarily on mileage rather than credit, making them a strong option for low-mileage poor-credit drivers.

Popular usage-based programs include:

Note that with Progressive Snapshot and GEICO DriveEasy, some drivers can see rates increase if driving habits show elevated risk, so review the terms carefully. Learn more about AI in car insurance pricing and how telematics data is factored into your rate.

Request Credit-Based Re-Rating

If your credit has improved since you first obtained coverage, contact your insurer and ask about a re-rating. Some companies will review your updated credit information mid-term or at renewal and adjust premiums accordingly. If you've improved your score by 50+ points, this single call could save you hundreds of dollars. You may also receive an adverse action notice if your rate was originally set based on a lower score, which entitles you to a free credit report and dispute rights.

Explore Non-Standard Insurer Options

For drivers who have difficulty securing standard coverage, carriers specializing in high-risk auto insurance pricing may offer competitive options. These carriers often place less emphasis on credit than mainstream companies, though premiums may still run 50-200% above standard rates. If you've been denied car insurance, poor credit is one of the most common triggers, and rebuilding your score can restore access to the standard market.

Frequently Asked Questions

Is it legal for insurance companies to check my credit?

Yes, it is legal in most states for insurers to check your credit and use credit-based insurance scores when determining rates. Federal law allows insurers to access your credit information for underwriting purposes under the Fair Credit Reporting Act. However, California, Hawaii, Massachusetts, and Michigan prohibit this practice entirely for auto insurance, while Maryland, Oregon, Utah, and Virginia have specific restrictions. Insurance companies typically conduct soft inquiries when providing quotes, which do not affect your credit score.

How long does it take for credit improvements to lower my insurance rates?

Credit improvements typically affect your insurance rates at your next policy renewal, which usually occurs every 6 or 12 months. Positive changes may appear on your credit report within 1 to 2 months of making improvements, but insurers generally review credit only at renewal. If you've made significant progress, such as paying down debt or resolving collections, contact your insurer directly to request a re-rating rather than waiting for automatic renewal. The sooner you start improving, the sooner you'll see savings.

Can I get car insurance without a credit check?

While most major insurers use credit-based scores in states where it's permitted, you do have options. If you live in California, Hawaii, Massachusetts, or Michigan, insurers are legally prohibited from checking your credit for auto insurance. In other states, telematics-focused insurers and pay-per-mile carriers weight rates heavily on mileage and driving behavior rather than credit. Comparing at least 5 to 7 companies with the help of a beginner's car insurance guide is the best way to find these options.

Will shopping for car insurance quotes hurt my credit score?

No, getting car insurance quotes will not hurt your credit score. When insurers check your credit to provide a quote, they perform a "soft inquiry" or "soft pull," which does not affect your score at all. This differs from "hard inquiries" that occur when you apply for loans or credit cards, which can temporarily lower your score. You can request as many insurance quotes as you need without any negative impact, making it all the more important to compare carriers actively.

Does paying my car insurance bill on time help my credit score?

Unfortunately, paying your car insurance premiums on time does not typically improve your credit score, as most insurance companies do not report payment information to credit bureaus. However, failing to pay can hurt your credit if your account goes to collections or unpaid balances are reported as debt. To build credit that leads to better insurance rates, focus on paying credit cards, loans, and mortgages on time, as these have the greatest impact on your credit-based insurance score. You can also explore tools like Experian Boost, which adds utility and rent payments to your credit file.
