Credit-Based Insurance Scores vs. FICO Scores
Most people know their credit score matters for mortgages and car loans — but it also plays a major role in how much you pay for home insurance. However, insurers don't actually use your standard FICO score. Instead, they generate a separate metric called a credit-based insurance score (CBIS), and the distinction matters.
What Is a Credit-Based Insurance Score?
A credit-based insurance score is a proprietary calculation derived from your credit history that insurers use to predict the likelihood you'll file a claim. A higher score signals lower risk, which translates to lower premiums. Unlike your FICO score — which predicts whether you'll repay a debt within 24 months — a CBIS is specifically calibrated to forecast insurance risk.
Here's how the two compare:
| Factor | Credit-Based Insurance Score (CBIS) | FICO Credit Score |
|---|---|---|
| Primary Purpose | Predicts insurance claim likelihood | Predicts loan repayment probability |
| Who Uses It | Home & auto insurers | Lenders, banks, landlords |
| Soft or Hard Pull? | Soft inquiry (no credit impact) | Hard inquiry (may affect score) |
| Demographic Exclusions | Race, income, gender, age excluded | Same exclusions apply |
| Score Range | Varies by insurer model | 300–850 |
What Factors Make Up a CBIS?
The five core inputs are the same as a standard credit report, but weighted differently:
- Payment History (~40%) — On-time vs. late payments
- Outstanding Debt (~30%) — Current balances relative to limits
- Length of Credit History (~15%) — Age of your oldest and average accounts
- New Credit Applications (~10%) — Recent hard inquiries or new accounts
- Credit Mix (~5%) — Variety of account types (cards, loans, etc.)
Factors like your income, race, marital status, age, and occupation are prohibited from being used in CBIS calculations.

How Much Does Your Credit Score Affect Home Insurance Rates?
The impact is larger than most homeowners realize. Insurers in most states heavily weight credit scores, and the premium gap between credit tiers can be dramatic.
Average Rate Differences by Credit Tier
According to recent research and rate analyses, here's what homeowners typically pay based on their credit profile:
| Credit Tier | Approx. FICO Equivalent | Avg. Annual Premium | vs. Excellent Credit |
|---|---|---|---|
| Excellent | 820+ | ~$2,490/yr | Baseline |
| Good / Medium | ~740 | ~$3,282/yr | +39% more |
| Fair / Low | ~630 | ~$4,490+/yr | Up to +80–100% more |
| Poor | Below 580 | ~$5,100+/yr | Up to +105% more |
Research by the Consumer Federation of America found that a typical homeowner with a low credit score pays nearly $2,000 more per year than a counterpart with a high credit score — and in 23 states, low-credit homeowners pay at least twice as much for the same coverage in the same location.
Even a "medium" credit score around 740 costs homeowners an average of $792 extra per year compared to those with excellent credit. Meanwhile, homeowners with poor credit devote up to 24% of total housing costs to insurance alone — up from 17% in 2020.
Understanding how home insurance underwriting works can help you see why insurers weigh credit so heavily alongside other risk factors like roof age, location, and claims history.

States That Prohibit Credit-Based Insurance Pricing
Not every state allows insurers to use your credit score when setting home insurance rates. If you live in one of the following states, your credit history cannot be used against you — at least for home insurance purposes.
States with the Strongest Protections
Key notes by state:
- California — Full ban on credit-based scoring for home insurance
- Maryland — Prohibits using credit history to set homeowners insurance rates
- Massachusetts — Rates cannot be based on credit under state law
- Michigan — Cannot use credit to deny, cancel, or set rates; limited exceptions apply
- Oregon — Credit cannot be used to cancel or non-renew a policy
- Hawaii & Utah — Strict limitations, though home insurance rules differ from auto
If you're in any of the other 43 states, insurers are permitted — and very likely — using your credit in their pricing model. The home insurance underwriting process in those states treats credit as one of the most influential rating factors.
How to Improve Your Credit Score for Lower Home Insurance Rates
The good news: credit scores can be improved, and the savings can be substantial. Below are the most effective strategies — and what to do if your credit needs time to recover.
Steps to Boost Your Credit-Based Insurance Score
1. Dispute Errors on Your Credit Report Studies suggest over 25% of credit reports contain errors such as incorrectly reported late payments, duplicate accounts, or outdated collections. Request your free report at AnnualCreditReport.com from all three bureaus — Experian, Equifax, and TransUnion — and dispute any inaccuracies. This is one of the fastest ways to see a score jump.
2. Pay Bills On Time, Every Time Payment history carries the most weight (~40%) in both your FICO and CBIS. Set up autopay or calendar reminders. Even one missed payment can cause a meaningful dip, while consistent on-time payments will steadily lift your score over 6–12 months.
3. Lower Your Credit Utilization Ratio Aim to use less than 30% of your available credit across all cards. Paying down balances — even partially — can produce a noticeable score improvement within 30–45 days once your creditors report updated balances.
4. Keep Old Accounts Open The length of your credit history accounts for roughly 15% of your score. Closing old credit cards shortens your average account age and can actually lower your score. Keep them open even if you rarely use them.
5. Avoid Opening New Accounts Unnecessarily Each new application generates a hard inquiry and lowers your average account age. Avoid applying for new cards or loans in the months before you plan to shop for or renew home insurance.
How Long Until Your Insurance Rates Improve?
Credit changes typically appear in your score within 30–45 days of being reported by creditors. However, meaningful rate improvements from insurers usually take 6+ months of consistent habits. Once your score climbs, proactively ask your insurer to re-pull your credit or shop competing quotes — insurers won't automatically lower your rate mid-term.
Options If You Have Bad Credit Right Now
If improving your credit will take time, you still have options:
Among insurers considered more lenient with credit, Westfield averages around $1,080/year for poor-credit applicants, AIG averages approximately $1,730/year, and Allstate offers flexible coverage options with bundling discounts. Rates vary significantly by location and home profile, so always compare multiple quotes.
If private market insurers won't offer coverage or rates are unaffordable, contact your state's FAIR Plan (Fair Access to Insurance Requirements) as a backstop option — though coverage is typically more limited.
Frequently Asked Questions
Does my credit score directly affect my home insurance premium?
Not directly — insurers don't use your FICO score itself. Instead, they pull your credit history and generate a credit-based insurance score (CBIS), which is a proprietary metric calibrated to predict claim likelihood. This score then influences your premium tier. A higher CBIS typically means lower premiums, and a lower CBIS can significantly increase what you pay.
How much can bad credit increase my home insurance rates?
The increase can be dramatic. Research shows that homeowners with poor credit pay an average of 105% more than those with good credit — nearly double the annual premium. In some states, the gap is even wider. For example, Pennsylvania homeowners with low credit scores pay up to 181% more than those with excellent credit for comparable coverage.
Which states don't allow credit scores in home insurance pricing?
California, Maryland, and Massachusetts fully prohibit the use of credit history in setting home insurance rates. Michigan has significant restrictions, and Oregon limits credit use for cancellations and non-renewals. If you live outside these states, it's very likely your insurer is factoring your credit into your premium.
Will shopping for home insurance quotes hurt my credit score?
No. Insurers use soft credit inquiries when pulling your credit history for insurance quotes. Soft pulls do not appear on your credit report as inquiries and will not affect your FICO score. You can freely shop multiple quotes without any negative credit impact.
What can I do to lower my home insurance if I have bad credit?
Start by disputing any errors on your credit report, paying down balances, and making all future payments on time — these moves can improve your score within a few months. In the short term, shop multiple insurers (some weigh credit less heavily than others), raise your deductible, bundle policies, and add safety features to your home. If you live in California, Maryland, or Massachusetts, your credit cannot be used against you at all.
