Insurance Score vs. Credit Score: How Insurers Really Calculate Your Rate

What Is an Insurance Score?

An insurance score is a three-digit number that predicts how likely you are to file a claim, not whether you'll repay a loan. FICO builds the most widely used version, and LexisNexis markets its own model called Attract, which scores consumers on a scale of 200 to 997. According to the NAIC, insurers adopted these scores in the 1990s to replace adjusters' subjective judgment, which had placed customers in incorrect risk tiers for decades.

Your average car insurance premium depends heavily on this number. A 2007 Federal Trade Commission study confirmed that credit-based insurance scores predict claim frequency even after controlling for income, race, and geography. That research still underpins the regulatory framework across 46 states today.

Checking an insurance quote triggers only a "soft pull" on your credit report, according to FICO. Soft inquiries don't appear on your credit history and won't lower your FICO score by a single point. Hard pulls, by contrast, come from loan or credit card applications and can temporarily reduce your score by 5 to 10 points.

Insurance Score vs. Credit Score: Side-by-Side Comparison

Both scores draw from the same Experian, Equifax, or TransUnion credit report. The critical difference lies in how each model weights five categories of data, according to FICO and the NAIC.

Credit Factor	FICO Credit Score Weight	Insurance Score Weight	Difference
Payment history	35%	40%	+5 pts for insurers
Outstanding debt	30%	30%	No change
Credit history length	15%	15%	No change
New credit inquiries	10%	10%	No change
Credit mix	10%	5%	-5 pts for insurers

That extra 5% emphasis on payment history means a single 30-day late payment can hurt your insurance score more severely than your FICO score. Meanwhile, having a diverse mix of mortgages, auto loans, and credit cards matters half as much to insurers as it does to lenders.

A "good" insurance score generally starts at 770 or above, according to Insurance.com. Scores below 500 place you in the highest-risk tier, where poor credit can raise full coverage rates by 98% compared to drivers with good scores, per ValuePenguin's 2026 analysis.

How to Check Your Insurance Score

Most articles on this topic tell you to "monitor your credit." That's useful, but it won't show you the actual number insurers see. Three specific reports give you direct access to the data behind your insurance score.

Compare your Attract score against your FICO score. If your FICO sits at 720 but your Attract score is 580, check your CLUE report for errors. According to the Consumer Federation of America, roughly 1 in 5 consumers has at least one error on their credit file that could affect insurance pricing.

States That Ban Credit-Based Insurance Scoring

Four states prohibit auto insurers from using credit data to set rates, according to the NAIC and state DOI filings.

State	Ban Status	Year Enacted	Key Detail
California	Full ban	1988	Proposition 103 banned all credit-based rating
Hawaii	Full ban	2009	HB 1440 prohibited credit use for auto and home
Massachusetts	Full ban	1998	Regulated through managed competition system
Michigan	Full ban	2020	No-fault reform bill eliminated credit scoring

Maryland takes a middle approach: auto insurers can use your credit history for initial pricing on new policies, but they cannot deny coverage, cancel a policy, or increase your renewal premium based on credit alone, per the Maryland Insurance Administration. Oregon, Nevada, and Utah also restrict credit-based scoring to varying degrees.

If you live in one of the 46 states that allow credit-based scoring, your insurance score influences every quote you receive. Drivers in Washington, D.C. face the steepest penalty: poor credit triples full coverage insurance rates compared to good credit, per ValuePenguin's 2026 state-by-state data.

How to Improve Your Insurance Score

Payment history accounts for 40% of your insurance score, so setting up autopay on every credit account delivers the single largest improvement. According to FICO, a single 30-day late payment can drop your insurance score by 50 to 100 points. Recovering from that hit typically takes 12 to 18 months of on-time payments.

Avoid filing claims for damage that barely exceeds your deductible. Paying $1,200 out of pocket on a $1,000-deductible policy keeps your CLUE report clean, which protects your insurance score at renewal. According to the Insurance Information Institute, 2 claims within 3 years can raise premiums by 20% to 40% at most carriers.

Your insurance score recalculates at renewal, not mid-policy. If you've spent 6 months paying down debt and correcting credit report errors, compare quotes from 5 or more insurers before your renewal date. Each company weighs the 5 credit factors slightly differently, so a score that's "average" at State Farm might qualify as "good" at GEICO.

Drivers on tight budgets should also explore low-income car insurance programs in their state, which may offer rate relief regardless of credit standing. California's Low Cost Auto Insurance Program, for example, provides liability coverage starting at $338/year for qualifying drivers.
