Why did my car insurance go up when I had no claims?

Your premium can increase even without claims due to statewide rate changes, higher vehicle repair costs, increased local claim activity, changes in credit-based insurance scores where permitted, lost discounts, address changes, or updates to your vehicle's risk rating.

Can insurance raise rates without telling me?

Insurance companies generally provide renewal notices that show your new premium before the next policy term begins. Notification requirements vary by state, so it is important to review all renewal documents before your payment due date.

Does credit affect car insurance?

In many states, insurers may use credit-based insurance scores as part of underwriting and rating decisions. Some states restrict or prohibit the use of credit information. According to the National Association of Insurance Commissioners (NAIC), most auto and homeowners insurers use credit-related data where permitted by law.

Will my rate go down if I stay with the same company?

Possibly, but staying with the same insurer does not guarantee lower premiums. Your rate can change because of company-wide pricing adjustments, claims trends, available discounts, driver information, vehicle factors, and coverage selections.

Is it better to lower coverage to save money?

Reducing coverage can lower your premium, but it may also increase your financial risk after an accident. Before reducing liability limits or vehicle protection coverage, consider reviewing deductible options, available discounts, and alternative ways to reduce costs.

How often should I compare car insurance quotes?

It is generally recommended to compare auto insurance quotes at least once a year. You should also shop for new quotes after major life changes such as moving, adding a driver, purchasing a vehicle, or receiving a significant premium increase at renewal.

How Bad Credit Affects Car Insurance Quotes by State

Reviewed by the AtozInsuranceusa editorial team.

Bad credit can raise your car insurance quote in states that allow insurers to use credit data. The insurer may use a score drawn from your credit report. That score can differ from the one in your banking app. State law sets the rules for its use.

California, Hawaii, and Massachusetts prohibit credit history use in auto insurance underwriting or rating. Other states place limits on certain uses. Maryland, for example, allows credit to affect the price of a new policy but bars credit from increasing a renewal premium.

Bad credit does not add one fixed fee to all quotes. Your insurer, record, car, cover, and state rules all matter. A low score also does not mean every company will refuse you.

Start with three checks:

Find the rule for personal auto insurance in the state where you insure the car.
Ask whether credit played a role in the quote and which report it used.
Compare quotes with the same limits, deductibles, drivers, and start date.

This guide covers insurance for your own car. Home, loan, and business rules can differ. The state examples below reflect the sources checked on October 1, 2026. Check with your state insurance department to confirm the rule for your plan.

What is an insurance score based on credit?

An insurance score uses parts of your credit record to help predict future claim risk. A lending score has a different role. It helps a lender judge if you will repay a debt. Both may use the same report. They need not weigh the facts in the same way.

That is why your bank app cannot tell you what an insurer will charge. The app may show one score. The insurer may use its own model and price rules.

Term	What it tells you	What it does not tell you
Credit report	Details about accounts and payment history	Your final price
Lending score	A model’s view of your chance of repaying debt	The score every insurer uses
Insurance score	A model’s view of claim risk using credit data	Whether you will have a crash
Insurance quote	The price for the terms and facts you chose	That another insurer will charge the same

The NAIC cites a FICO estimate that about 95% of auto insurers use these scores where the practice is allowed. This is an estimate of insurer use, not a measure of how many drivers pay more.

A score also does not measure your worth or prove you drive poorly. It is a tool for judging risk across groups. You should still check your own record and the other facts in the quote.

Which state rules can change the effect of bad credit?

This table shows some key rules. It does not list all state laws. A state that permits credit use may still set rules for denials, renewals, thin files, and the data a firm can use.

State	Key rule for auto insurance	What to ask next
California	Credit history cannot serve as an auto underwriting or rating factor.	Which allowed factors explain my price?
Hawaii	Credit history cannot serve as an auto underwriting or rating factor.	Did the insurer use my driving and vehicle details correctly?
Massachusetts	Insurers cannot use credit data for auto underwriting or rating.	What factors caused the quote to change?
Maryland	Credit may affect new policy pricing, but cannot raise a renewal premium. A credit surcharge cannot exceed 40%.	Is this a new quote or a renewal review?
Michigan	State law bars using an individual’s credit score to set or maintain auto rates. The law’s terms and scoring rules matter.	Ask DIFS how the company’s scoring method complies.
Oregon	Credit use is allowed. You can ask once a year for a fresh credit rating. That review cannot raise the bill.	Can I request the credit review now?
Washington	The regulator says no current ban stops insurers from using credit to set prices.	Did credit affect this quote, and what notice applies?
Texas	Credit use is allowed, with limits and rights for some major life events.	Does my situation qualify for an exception?

If your state does not appear here, do not assume it has no safeguards. Ask its insurance department about credit use for new quotes, renewals, and the right to buy a plan. Each is a separate question.

Why should Michigan drivers check the exact rule?

Michigan’s law uses a defined term, “credit score.” The Michigan Department of Insurance and Financial Services (DIFS) says insurers must show that score filings comply with the law if the insurance score relies wholly or partly on a credit score as defined in the statute.

The NAIC chart also describes permitted uses of credit information under separate Michigan provisions. Do not read the score ban as a blanket ban on all credit data. Ask what drove your quote. If the answer is unclear, send the quote and explanation to DIFS for help.

Why do new quotes and renewals need separate checks?

A rule may let a firm use credit for a new plan but set limits when you renew. Maryland makes that distinction. It also bars using credit to refuse coverage, cancel a policy, or refuse renewal.

Ask which rule the insurer is using. Do not assume a fresh quote from another company follows the same rules as your current renewal.

How much can bad credit raise your quote?

No single percent change will tell you what you will pay. Each firm has its own price rules. Each state sets limits. Your cover and driving record affect the total too.

Use actual quotes to measure your options. The prices below are made up. They do not show the effect of credit alone. They are not average prices.

Sample quote	Cost for six months	Payment pattern	What to compare
Company A	$1,200	$200 each month for six months	Same limits and deductibles
Company B	$960	$160 each month for six months	Same drivers and car use
Company C	$900	$300 first, then five payments of $120	Same fees and benefits

Assume all plan terms and fees match. Company B costs $240 less than A for the term, or 20% less. Company C costs another $60 less, but requires more cash at the start.

You could not say that credit caused the whole gap. Each quote includes other factors. Ask each insurer how credit changed its offer. Would a new score change the rate? What else drove the price?

Be cautious with claims that “bad credit always doubles insurance.” A study may use set driver traits, states, and cover levels. Its average cannot tell you what your next bill will be.

Why can credit matter when your driving record is clean?

Firms that use credit see it as a separate risk factor. A clean driving record does not erase that factor. The NAIC lists driving history, prior coverage, car use, mileage, and other details among common rating factors.

Check the whole quote, not just credit. A wrong commute estimate, missing discount, or wrong claim can affect price too.

For example, suppose you stopped driving to work but the quote still shows your old annual mileage. Correct that fact and request a revised quote. That change is separate from your credit and may help you compare more fairly.

If you moved, confirm where the insurer lists the car. Our guide to insurance addresses and driver’s licenses explains why accurate address details matter.

What credit details might an insurer review?

Texas consumer guidance lists past due payments, open accounts, amounts owed relative to available credit, and applications for new credit among the details insurers may review. Other states and models can set different rules.

Ask for the main reasons behind a poor result. “Your credit affected the quote” is less useful than knowing which report and facts drove the choice.

Do not assume your pay forms part of the score. Your pay and your credit record are distinct. Low pay does not have to mean poor credit.

Also distinguish an insurance inquiry from a loan inquiry. Texas, for example, bars insurers from using insurance related credit checks against you.

Is having no credit history the same as bad credit?

No. A thin file may mean the report has too little data to score. It does not prove that you missed bills.

States may limit how insurers treat missing or thin credit files. The NAIC’s state chart lists such limits for some states. Ask what rule the insurer applies when it cannot score your file.

This matters for young drivers and people who do not borrow much. Do not open a loan solely because you hope it will reduce an insurance bill. First ask how the insurer rates your file now.

What rights do you have if credit leads to a worse offer?

Federal law requires an adverse action notice when a consumer report plays a role in certain adverse insurance decisions. That can mean a denial or a higher bill. The FTC explains that the report need only play a part in the decision.

The notice should name the reporting firm. It should explain how to get a free report and dispute errors. You generally have 60 days after the notice to ask that firm for the free report.

Keep the notice with your quote. Check the following:

Which company supplied the report?
What date did the insurer use it?
Does the notice state how to get a copy?
Which reasons or score factors appear?
How can you ask for a review once the firm fixes an error?

A notice does not prove that the data is wrong. It gives you a route to check it. You may still get a policy, even if the firm did not give you its lowest price.

What should you ask the insurer?

You can ask: “Please explain whether credit affected my quote. Which report did you use, and how can I ask for a fresh review if I find an error? Please keep my limits the same in any new quote.”

Write down the response and save the quote number. That makes it easier to track whether the next price reflects fixed data, new terms, or both.

How do you find and dispute credit report errors?

Get your reports through AnnualCreditReport.com, the authorized source identified by the CFPB. You can review reports from the three nationwide credit reporting companies online for free each week. Checking your own report does not hurt your score.

Read each account, not just the score. Look for an account you do not recognize, a payment marked late in error, a wrong balance, or a record that belongs to someone else.

If you find a problem:

Mark the exact entry and explain what is wrong.
Gather proof, such as statements or a payment record.
Dispute the entry with the reporting company.
Send the dispute to the firm that supplied the data too.
Save copies and review the response.
Ask the insurer to rerun the quote once the data is right.

The CFPB recommends disputing inaccurate or incomplete information with both the reporting company and the source of the data.

Keep paying for your car insurance while you work on the dispute. A credit review does not extend your policy or change its payment due date.

Do not pay someone who promises to remove accurate negative history. The FTC warns that credit repair firms cannot legally erase accurate, current negative information from your report.

Can illness, job loss, or identity theft qualify for an exception?

Some states grant rights if a major life event harms your credit. The events, proof, and steps vary.

Texas law, for example, provides a written request process for reasonable exceptions after certain extraordinary events. The insurer may ask for proof of the event and how it hurt your credit.

Ask about this if illness, a death in the family, divorce, job loss, or identity theft harmed your record. You may need to ask for help. That does not remove all other price factors.

Prepare a short timeline. Explain when the event took place, which accounts it affected, and what proof you can provide. Ask what the insurer needs before sending sensitive records. Keep copies and request a written response.

If the firm gives an unclear answer, ask your state insurance department to explain the local rule. Even if it sets some credit data aside, it does not promise a set price.

How can you lower costs while you work on credit?

Start with quotes from several insurers. An agent who sells plans from more than one firm may help you find more quotes. Ask whether each quote uses credit and what else affects the price.

Compare the same limits, drivers, car, use, and dates. A lower quote can reflect less cover rather than a better price. Check the total term cost and the amount due now.

Ask about valid discounts for low mileage, safe driving, good grades, approved courses, or several policies. Offers vary. Texas’s shopping checklist suggests reviewing discounts, payment choices, and deductibles.

If you raise your share of a claim, be sure you can pay it. A made up change from $500 to $1,500 adds $1,000 to your share of a covered claim. Compare that risk with the true savings.

A smaller first payment may help your cash flow without lowering your full bill. Read about no down payment car insurance and ask the provider for the full list of payments.

If the car has a loan, keep the lender’s required coverage. Our guide to insurance requirements for financed cars explains why a bare minimum quote may not fit.

Will improving your credit lower your insurance rate?

It may help where credit use is legal, but you need a fresh review under the plan’s rules. The insurer may not check for changes as soon as your report improves.

Oregon’s regulator says consumers can request a credit rating once a year. The review can reduce the premium, but it cannot increase it. Other states have their own rules, so check local rules before you seek a new score.

To help your credit, the CFPB recommends paying bills on time and keeping balances low relative to card limits. You do not need to carry a card balance and pay interest to build a good record.

Set reminders for due dates. If you set bills to pay on their own, check that you have enough funds. Keep a simple list of bills so a missed notice does not become a missed payment.

Even after your credit improves, repair costs, driving changes, or other rate changes may offset part of the gain. Compare the new quote with other offers. Do not expect a set dollar cut.

Frequently asked questions

What credit score do I need for cheap car insurance?

No score guarantees a cheap quote. Insurers may use different insurance scores and price groups. Your state, record, cover, and car also matter. Get quotes with your own facts. Do not rely on a lending score cutoff.

Does getting a car insurance quote lower my credit score?

Insurance quote checks generally use soft inquiries. Progressive states that its quote inquiry does not affect your credit rating. Ask the provider how it checks credit, especially if a separate company offers financing for the premium. Applying for a loan is a separate step.

Can I buy car insurance without a credit check?

Some insurers do not use credit for pricing, and some states prohibit that use. Ask each provider directly. Do not assume “no credit check” means the lowest price or no other checks. Compare the final cost and coverage with standard offers.

Can bad credit cause a denial or nonrenewal?

State law sets the rules. The NAIC notes that most states restrict using credit as the sole reason for certain adverse decisions. Some have stronger limits. Read the insurer’s reason and ask your regulator about the rule for your state and policy.

Will paying my car insurance bill build credit?

Do not assume so. Paying an insurance premium is not the same as repaying a reported credit account. Ask the insurer whether it reports payments. Pay on time to keep coverage active, and use your credit reports to see which accounts actually appear.

Why did my rate rise even though my credit improved?

Credit is just one factor. Changes in claims history, drivers, mileage, coverage, or company rates can affect the total. Ask for an explanation and check whether the insurer used new credit data. Compare matching quotes before deciding whether to switch.

What should you do next?

Check your state’s rule first. Then ask whether credit affected the quote, review the report, and correct errors. Compare equal coverage across insurers and request any review or exception that your state allows. Keep your plan active while you work through those steps.
