Introduction
You haven’t had an accident.
You haven’t filed a homeowners claim.
You haven’t received a speeding ticket.
Your car hasn’t changed.
Your house hasn’t changed.
Yet when you shop for insurance, another person with apparently similar coverage can receive a:
very different premium.
One possible reason is something many consumers don’t immediately associate with insurance:
credit information.
In states where the practice is permitted, insurers may use what’s known as a:
credit-based insurance score
when underwriting or pricing auto and homeowners insurance.
The National Association of Insurance Commissioners (NAIC) says insurers often use consumer credit information when deciding whether to offer auto or homeowners insurance and how much coverage will cost. These scores are intended to predict insurance-loss risk rather than the likelihood that you’ll repay a loan.
That distinction is important.
Your:
regular credit score
and your:
credit-based insurance score
aren’t necessarily the same thing.
And the rules aren’t uniform nationwide.
Some states restrict how insurers can use credit information, while others prohibit certain uses altogether.
So does your credit secretly affect your insurance?
For millions of Americans:
potentially, yes.
But the full story is much more complicated.
What Is a Credit-Based Insurance Score?
A credit-based insurance score is a statistical score built using information from your:
credit history.
Insurers use it to estimate:
the likelihood of future insurance losses.
The Federal Trade Commission explains that some insurance companies use information from consumers’ credit reports to help determine whether to offer insurance and what premium to charge.
The NAIC describes the score similarly: it is based partly or entirely on credit-history information and is used to predict insurance-loss risk.
Credit Score vs. Insurance Score
These terms are often confused.
Traditional Credit Score
Primarily designed to estimate:
credit repayment risk.
Lenders may use it when considering:
Credit cards
Mortgages
Auto loans
and:
Other borrowing.
Credit-Based Insurance Score
Designed to help estimate:
insurance loss or claim risk.
Insurers may combine that information with many other rating variables.
So your insurer isn’t necessarily looking at the same score your bank sees when you apply for:
a mortgage.
Why Would Credit Have Anything to Do With Insurance?
This is the controversial part.
Why should:
paying a credit-card bill
have anything to do with:
crashing a car?
Insurers argue that statistical data demonstrates a relationship between certain credit characteristics and insurance losses.
The FTC’s major study of automobile insurance found that credit-based insurance scores were effective predictors of the number and total cost of claims in the dataset it examined. However, the FTC also said the precise reason for the relationship wasn’t clear.
That’s an important distinction.
The argument isn’t necessarily:
“Poor credit causes accidents.”
Instead:
insurers say credit characteristics correlate statistically with insurance losses.
Correlation and causation aren’t the same thing.
How Common Is Credit-Based Insurance Scoring?
Very common—where state law allows it.
According to the NAIC’s March 2026 update, FICO estimates approximately:
95% of auto insurers
and:
85% of homeowners insurers
use credit-based insurance scores in states where they’re legally permitted as an underwriting or risk-classification factor.
So this isn’t a niche insurance practice.
It can potentially influence:
millions of policies.
What Credit Information Can Affect an Insurance Score?
Insurance-scoring models vary.
The FTC has identified factors commonly associated with credit-based insurance scoring such as:
Payment delinquencies
Bankruptcy/public-record information
How much available credit you’re using
Length of credit history
Certain types of credit accounts
and:
Credit activity.
But insurers don’t necessarily use:
every factor
or:
weight each factor identically.
Models are proprietary and state laws can restrict specific factors.
Your Payment History Can Matter
Repeated:
late payments
may negatively affect credit information used in some insurance-scoring models.
Suppose two drivers have:
Similar cars
Similar ages
Similar addresses
Clean driving records
and:
Same coverage limits.
Driver A has a stronger credit-based insurance score.
Driver B has a weaker score.
In a state permitting the practice, their premiums could differ partly because of:
credit-related risk classification.
Credit Utilization Can Matter
Suppose you have:
$20,000
of total available revolving credit.
You currently owe:
$18,000.
That’s:
90% utilization.
A high proportion of balances relative to available credit may negatively affect traditional credit scoring and can also be relevant to some insurance-scoring models.
By contrast, someone using:
$2,000
of that same $20,000 limit has much lower utilization.
Exact insurer models differ.
Bankruptcy Can Matter
Bankruptcy and other serious adverse credit events can be relevant to insurance scoring where state law permits.
But the impact isn’t:
identical everywhere.
State laws may limit:
which information can be used
how old it can be
and:
how heavily credit can influence a premium.
Never assume a bankruptcy automatically means:
“My insurance will double.”
Pricing is insurer- and state-specific.
Does Checking an Insurance Quote Hurt Your Credit?
Consumers often worry:
“If five insurers check my credit, will my regular credit score drop?”
Insurance inquiries generally aren’t treated the same way as applying for a new loan.
More importantly, the relevant rules and scoring treatment should be distinguished from:
hard credit inquiries for new borrowing.
If you’re concerned, ask the insurer whether its insurance inquiry affects your consumer credit score before authorizing it.
Don’t avoid comparison shopping merely because you assume:
every insurance quote damages your credit.
Credit Is Only One Insurance Rating Factor
Even in states where insurers use credit, your insurance score isn’t generally the only factor determining your premium.
Auto insurers may also consider:
Driving record
Claims history
Age
Location
Vehicle
Annual mileage
Coverage limits
Deductible
and other legally permitted characteristics.
For homeowners insurance, factors can include:
Property location
Replacement cost
Construction
Roof characteristics
Prior claims
Fire protection
Deductible
and:
Catastrophe exposure.
Credit may be:
one layer of a much larger pricing model.
Example: Two Identical Drivers
Consider:
Driver A
Age: 40
Vehicle: Same SUV
ZIP code: Same
Driving record: Clean
Annual mileage: 10,000
Coverage: Same
Driver B
Everything is identical.
But their insurance-based credit classifications differ.
Imagine the insurer’s rating model produces:
Driver A:
$1,600/year.
Driver B:
$2,050/year.
Difference:
$450 annually.
This example is hypothetical.
It demonstrates how a credit-related rating factor could affect the final premium where permitted.
It does not mean a particular score creates a predictable $450 difference.
There’s No Universal “700 Credit Score Insurance Discount”
This is one of the biggest misconceptions.
You might see advice saying:
“Get your credit score above 700 and your insurance drops 20%.”
That’s far too simplistic.
Insurers can use:
different scoring models
different rating tiers
different weighting
and:
different state-approved formulas.
Your consumer FICO score isn’t necessarily the insurance score being used.
There is no universal rule such as:
650 = expensive insurance
700 = average insurance
800 = cheap insurance.
Your Insurer May Not Tell You the Exact Formula
Credit-based insurance models can be proprietary.
You may know that:
credit information affected your rate
without being given the insurer’s entire mathematical model.
However, federal and state consumer-protection laws can require notices when information from consumer reports contributes to an adverse insurance decision.
Your rights depend partly on:
what happened
and:
where you live.
State Law Changes Everything
This may be the most important section of the article.
There isn’t one nationwide rule governing how credit-based insurance scores can affect every auto and homeowners policy.
The NAIC notes that states place significant restrictions on the use of these scores. In most states, credit-based insurance scores generally cannot be the sole reason for certain adverse actions, while some jurisdictions impose stronger limitations.
So before asking:
“Does credit affect my insurance?”
ask:
“What does my state allow?”
Some States Restrict or Prohibit Credit-Based Insurance Scoring
State rules differ substantially.
The NAIC maintains state-by-state information regarding credit-based insurance scoring and notes that some states prohibit or significantly restrict its use.
That means a consumer in:
State A
could experience a different credit-related insurance-rating system from someone living in:
State B.
Never apply a national insurance article blindly to your state.
Maryland Shows How Complicated the Rules Can Get
Maryland provides an excellent example.
For:
homeowners insurance,
Maryland says insurers aren’t allowed to use your credit history to refuse coverage, cancel your policy or determine your homeowners premium.
But:
auto insurance is different.
Maryland says some auto insurers can consider credit history when initially determining a new policy’s premium, subject to specific restrictions.
So even within:
the same state,
credit rules can differ depending on:
the type of insurance.
Maryland Auto Insurance Has Specific Protections
Maryland says an insurer using credit for private passenger auto insurance cannot:
Increase your renewal premium because your credit history worsened
Apply a credit-based surcharge greater than 40%
or use certain prohibited factors, including:
Number of credit inquiries
Lack of credit history
and:
Credit factors more than five years old.
Maryland also permits consumers to request a credit-history recheck once per policy period.
If credit improves:
the renewal premium may potentially decrease.
If it worsens:
that deterioration can’t be used to increase the renewal premium under the Maryland rule.
That’s a perfect illustration of why:
state-specific rules matter.
Credit Can Affect Auto and Home Insurance Differently
Don’t assume:
“My insurer uses credit for my car, so it must use credit for my house.”
That isn’t necessarily true.
Different insurance lines can operate under:
different laws
different rating models
and:
different restrictions.
Maryland is again a clear example: credit is prohibited for homeowners pricing but can be used in specified ways for a new private-passenger auto policy.
What About Renters Insurance?
Credit-based insurance information can also be relevant to property insurance in some jurisdictions.
However, the same warning applies:
state law controls.
Don’t assume the rules applying to:
Auto
also apply identically to:
Homeowners
or:
Renters.
Ask the insurer or state insurance regulator.
Does Credit Affect Life Insurance?
This article is primarily about:
auto and property insurance.
Life insurance underwriting is different.
Life insurers primarily evaluate mortality-related factors such as:
Age
Health
Nicotine use
Medical history
Occupation
and:
Lifestyle.
Consumers shouldn’t assume the auto/home credit-based insurance-score system described here applies identically to:
term life insurance.
What About Health Insurance?
Again:
different market.
In ACA-regulated individual health insurance, premium rules are governed by federal and state health-insurance requirements.
The credit-based auto/home insurance scoring system discussed in this article shouldn’t be generalized to:
health insurance.
Why Consumers Call It a “Secret”
Insurers aren’t necessarily secretly accessing information illegally.
The bigger problem is:
many consumers don’t realize credit can be part of insurance pricing at all.
The NAIC specifically identifies consumer awareness as an issue, noting that many consumers don’t understand credit-based insurance scoring or may not know that credit characteristics are being used to create a score affecting insurance.
So “secret” is better understood as:
hidden from ordinary consumer awareness,
not:
an illegal secret system.
Why Credit-Based Insurance Scores Are Controversial
Supporters argue that credit-based insurance scores:
Improve risk classification
Help insurers price policies more accurately
and:
Can lower premiums for consumers statistically associated with lower losses.
The FTC’s auto-insurance research found that credit-based scores predicted claim frequency and cost in its dataset.
But critics raise important concerns.
The Fairness Debate
The FTC also found differences in insurance-score distributions among racial and ethnic groups and concluded that the use of scores likely resulted, on average, in some groups paying relatively more than others.
This is one reason the issue remains:
politically
and:
regulatorily controversial.
Consumer advocates have questioned whether credit-related financial circumstances should influence:
the price of legally required auto insurance
or essential homeowners coverage.
Insurers counter that the scores provide:
statistically useful risk information.
Both sides are discussing a real policy trade-off.
Correlation Doesn’t Explain Why
The FTC found predictive value.
But it also said the reason credit-based insurance scores predict insurance losses isn’t completely clear.
That’s important.
The data may show:
correlation.
But that doesn’t necessarily establish:
a simple causal explanation.
So statements such as:
“People with poor credit are bad drivers”
are unsupported and misleading.
Financial Hardship Can Make the Issue More Complicated
Imagine someone experiences:
Job loss
Divorce
Medical expenses
or:
Natural-disaster-related financial stress.
Their credit could deteriorate even though:
their driving hasn’t changed.
This is one reason many states have enacted consumer protections around extraordinary life circumstances and how insurance scores can be used.
Exact protections vary.
If a major life event damaged your credit, ask your insurer whether:
an extraordinary-life-circumstance exception
or similar state protection applies.
Credit Report Errors Can Cost You
This is where the issue becomes especially practical.
Suppose your credit report incorrectly shows:
a delinquent account.
That information could hurt:
Loan pricing
and, where permitted:
insurance scoring.
The FTC recommends checking your credit reports and disputing inaccurate information.
If your insurer uses credit information, correcting an error could potentially improve:
your insurance position too.
How to Check Your Credit Reports
The federally authorized source for free credit reports is:
Review reports from:
Equifax
Experian
and:
TransUnion.
Look for:
Accounts that aren’t yours
Incorrect balances
Incorrect late payments
Duplicate accounts
Wrong account status
and:
Identity-theft activity.
Don’t wait until:
your insurance renewal
to discover an error.
Will Improving Your Credit Immediately Lower Your Insurance?
Not necessarily.
Even if your credit improves:
tomorrow,
your insurer may not immediately rerate your policy.
The timing depends on:
State law
Insurer practices
Policy renewal
and:
When credit information is refreshed.
Maryland, for example, requires insurers using credit for qualifying auto policies to obtain new credit scores periodically and also allows policyholders to request a recheck once during a policy period.
Other states may operate differently.
Improving Credit Shouldn’t Be an Insurance “Hack”
Don’t take out unnecessary loans or manipulate accounts just to:
game your insurance score.
Insurance-scoring models are proprietary.
You don’t know exactly how a particular insurer weights each variable.
Instead, focus on ordinary healthy credit habits:
Pay bills on time
Keep revolving balances manageable
Correct credit-report errors
Avoid unnecessary debt
and:
Monitor your credit reports.
Those actions can benefit your overall finances regardless of their insurance impact.
Don’t Close Every Credit Card Before Shopping for Insurance
Someone might think:
“Fewer credit cards must mean a better insurance score.”
Not necessarily.
Closing old accounts can affect:
available credit
credit utilization
and potentially:
credit-history characteristics.
Don’t restructure your financial life based on guesses about a proprietary insurance model.
Don’t Open Accounts to Manipulate Your Insurance Score Either
The opposite strategy is equally questionable.
Opening:
five new credit cards
to increase available credit isn’t a reliable insurance strategy.
It could alter multiple credit characteristics simultaneously.
Make credit decisions based primarily on:
sound personal finance principles.
Shop Around Even If Your Credit Is Weak
This is extremely important.
Insurers don’t all:
Use identical scoring models
Weight credit identically
or:
Combine credit with other factors identically.
Maryland’s regulator explicitly notes that some auto insurers use credit and some don’t.
Therefore, a weaker credit profile doesn’t necessarily mean:
every insurer will charge the same high premium.
Get multiple quotes.
Example: Three Insurers, Same Driver
Suppose the same driver receives:
Insurer A — $2,500/year
Insurer B — $2,050/year
Insurer C — $1,750/year.
All three have access to broadly similar applicant information.
But their:
Rating models
Risk appetite
Discounts
and:
Credit weighting
may differ.
Annual difference between A and C:
$750.
These figures are hypothetical, but the principle is real:
shopping matters.
Compare Identical Coverage
Don’t celebrate a:
$500 cheaper quote
until you check whether it has:
Lower liability limits
Higher deductible
No collision
No comprehensive
or:
Different endorsements.
Compare:
like with like.
For auto insurance, that means keeping:
Liability
Collision deductible
Comprehensive deductible
Uninsured/underinsured motorist coverage
and other major features as comparable as possible.
Credit Can Be Hidden Behind a “Tier”
Sometimes you may not see a line on your quote saying:
Credit adjustment: +$400.
Instead, credit information may contribute to:
A rating tier
Risk classification
or:
Eligibility for a particular pricing level.
The NAIC explains that insurers may use credit-based insurance scores to assign consumers to risk groups and adjust premiums according to the resulting classification.
That’s another reason the effect can feel:
invisible.
What Is an Adverse Action Notice?
If information from a consumer report negatively affects an insurance decision, federal consumer-reporting requirements may give you rights to information about that decision.
An adverse-action notice can help identify:
The consumer reporting agency involved
and:
Your rights regarding the report.
If you receive such a notice:
don’t ignore it.
Review the report for accuracy.
What If You’ve Never Used Credit?
A:
thin credit file
or:
no credit history
can create another question.
State laws may restrict how insurers treat consumers who lack credit information.
For example, Maryland prohibits certain auto insurers from using the absence of or inability to obtain credit history as a rating factor.
Again:
your state matters.
Does Paying Insurance on Time Build Your Credit?
Usually, paying ordinary insurance premiums isn’t the same as paying:
a credit account.
Don’t assume your monthly car-insurance payment automatically builds a traditional credit score.
However, unpaid debts that eventually enter collections can create broader financial consequences.
Pay insurance premiums on time primarily to:
avoid cancellation or coverage lapses.
A Coverage Lapse Can Create Another Problem
Suppose financial stress causes:
missed insurance payments.
Your policy cancels.
Later you shop for insurance again.
Even aside from credit, a:
lapse in prior coverage
can itself affect auto-insurance pricing or eligibility in some markets.
So financial hardship can potentially create:
multiple insurance consequences.
Credit Isn’t Why Every Premium Increase Happens
This is essential in 2026.
If your homeowners premium jumps:
15%
don’t automatically blame your credit.
Rates can rise because of:
Higher rebuilding costs
Catastrophe losses
Wildfire exposure
Severe convective storms
Hail
Reinsurance costs
Roof risk
and:
Insurer-wide rate changes.
Similarly, auto premiums can increase because of:
Repair costs
Vehicle technology
Medical costs
Theft
Litigation
and:
Claims trends.
Credit is only:
one possible factor.
Ask Your Insurer Directly
A simple question can help:
“Does credit information affect my insurance premium?”
Then ask:
“What rights do I have to request a re-evaluation if my credit improves?”
And:
“Was credit information responsible for an adverse pricing decision?”
The answer will depend on:
Your insurer
Your state
and:
Your policy type.
Can Better Credit Save You Money?
Potentially.
Where credit-based insurance scoring is permitted, stronger credit-related characteristics may place a consumer into a:
more favourable insurance risk tier.
But there is no universal savings percentage.
Don’t believe claims like:
“Improving your score 50 points saves exactly $400.”
Insurance pricing doesn’t work that simply.
A Better 2026 Insurance Strategy
Instead of obsessing over a specific insurance score, focus on four areas:
1. Maintain Healthy Credit
Pay obligations on time and keep balances manageable.
2. Check for Errors
Incorrect credit information shouldn’t be increasing your financial costs.
3. Shop Multiple Insurers
Different carriers price the same consumer differently.
4. Review Coverage
Make sure savings don’t come from accidentally reducing protection.
Your Credit-and-Insurance Checklist
Before your next auto or homeowners renewal:
- Find out whether your state allows credit-based insurance scoring.
- Ask whether your insurer uses credit.
- Review all three credit reports.
- Dispute inaccurate information.
- Pay bills on time.
- Reduce excessive revolving balances where financially appropriate.
- Avoid unnecessary new debt.
- Don’t close accounts merely to manipulate an insurance score.
- Ask whether an extraordinary-life-circumstance exception applies.
- Review any adverse-action notice.
- Ask whether improved credit can trigger rerating.
- Shop several insurers.
- Compare identical coverage.
- Check deductibles.
- Review discounts.
- Check claims history.
- Review annual mileage.
- Check vehicle information.
- Review property information.
- Re-shop periodically.
Frequently Asked Questions
Does my credit score affect my car insurance?
It can. In states where credit-based insurance scoring is permitted, insurers may use credit information as one factor in underwriting or pricing auto insurance. State restrictions vary considerably.
Does my normal FICO score determine my insurance premium?
Not necessarily. Credit-based insurance scores are designed for insurance-loss prediction and aren’t necessarily the same as the consumer credit score used by lenders.
Can poor credit increase my insurance rate?
Potentially, where permitted. Credit information can contribute to the risk tier or premium assigned by an insurer. But the effect depends on state law and the insurer’s rating model.
Does good credit guarantee cheap insurance?
No. Driving history, claims, vehicle, location, coverage, property characteristics and many other factors can still produce a high premium.
Does checking insurance quotes hurt my credit?
Don’t assume insurance shopping works like applying for multiple loans. If concerned, ask the insurer how its credit inquiry is classified and whether it affects your consumer credit score.
Can insurers deny me solely because of bad credit?
Rules vary. The NAIC says most states impose restrictions on using credit-based insurance scores as the sole basis for certain adverse underwriting or rating actions.
Can credit affect homeowners insurance?
Yes, in jurisdictions where permitted. But some states restrict or prohibit it. Maryland, for example, prohibits credit history from being used to price homeowners insurance.
Why do insurers use credit?
Insurers argue that credit-based insurance scores statistically help predict future insurance losses. The FTC found predictive relationships in its auto-insurance research, although the reason for the relationship wasn’t fully clear.
Will fixing a credit-report error reduce my premium?
Potentially, if credit is used in your state’s insurance pricing and the error materially affected your insurance score. It isn’t guaranteed or necessarily immediate.
Should I improve my credit before shopping for insurance?
Maintaining healthy credit is sensible generally. But don’t postpone comparison shopping—different insurers can price the same risk very differently.
Final Thoughts
Your insurance company doesn’t necessarily see:
“Credit Score: 680”
and simply add:
$500
to your premium.
The system is more complicated.
In states where it’s permitted, insurers may use:
credit-based insurance scores
alongside many other variables to predict insurance losses and determine:
risk classifications
and:
premiums.
The NAIC says the practice remains widespread where legally allowed, with FICO estimating that about 95% of auto insurers and 85% of homeowners insurers use credit-based insurance scores in those markets.
But:
your state matters enormously.
Some states impose substantial restrictions.
And even within the same state, rules can differ between:
auto
and:
homeowners insurance.
Maryland demonstrates this clearly: credit use is prohibited in homeowners pricing, while some credit use is permitted for pricing new auto policies under specific restrictions.
So don’t assume:
poor credit automatically means expensive insurance.
And don’t assume:
excellent credit guarantees cheap insurance.
Instead:
Check your credit reports
Correct errors
Maintain responsible credit habits
Understand your state’s rules
and:
shop multiple insurers.
The most important thing to remember is that the insurance score you never see can potentially affect the premium you see every month.
