Does Your Credit Score Affect Your Car Insurance?

For most drivers in most states, yes, your credit can affect what you pay for car insurance. Insurers do not use your credit score the way a lender does, but many build a separate credit-based insurance score from your credit history and use it as one rating factor among many. A strong score moves a meaningful slice of your premium down, while a weak, thin, or missing credit file leaves that discount on the table. How much it matters depends on the carrier, your state, and the rest of your profile, and a handful of states do not allow the practice at all.

What our filed-rate data shows

Rather than estimate, we read Clearcover's actual rate manual on file with the Arizona regulator (SERFF tracking CLEA-134142856, effective July 15, 2024). The filing contains an insurance-score tier table with roughly fifty levels plus special Neutral and No Hit tiers, and every factor sits at or below 1.0000, so the table works as a discount schedule: the reference tier pays full price and better tiers pay less. Reading the filed cells directly:

• The reference tier (Level 1) carries a 1.0000 factor, the full-price anchor.
• The top-discount tier (Level 50, continuous coverage) is 0.4163, about 58 percent below baseline, a roughly 2.4-times swing from one end of the ladder to the other.
• A higher-mid tier (Level 40) is 0.4978 and Level 29 is 0.6061, showing the discount builds gradually as the score improves.
• The Neutral tier (average or inconclusive score) is 0.6353.
• The No Hit tier (no credit record found) is 0.7514, better than baseline but well short of the deepest discount.

Every figure is transcribed cell by cell from Clearcover's filed Arizona rate pages; they are one company's filed multipliers in one state, not a market average, and another carrier or state would carry its own values. You can look up the same public filings through the state insurance department that regulates your own market.

Neutral, No Hit, and thin credit files

Not everyone has a rich credit history, and the filed table shows how carriers handle that. In Clearcover's Arizona filing, a Neutral score maps to a 0.6353 factor and a No Hit, meaning no credit record was located, maps to 0.7514. Both sit below the 1.0000 baseline, so a thin file is not automatically penalized to the top of the table, but neither earns the deep 0.4163 discount reserved for the strongest scores. This matters for young drivers, recent arrivals, and anyone who has deliberately avoided credit. Building even a modest, well-managed credit history over time can move you from a Neutral or No Hit tier toward the discounted tiers, one of the few rate levers that rewards ordinary financial habits rather than driving behavior.

How to improve the credit side of your rate

Because the insurance score is built from your credit file, the levers that help it are the same ones that build good credit generally, and they compound with every other discount:

• Pay every bill on time; payment history is the heaviest input in most scoring models.
• Keep credit-card balances low relative to limits, which lifts the score without new borrowing.
• Avoid opening several new accounts right before shopping insurance, since new credit can dip the score.
• Build history if your file is thin, since moving off a Neutral or No Hit tier toward the discounted tiers is worth real money.
• Compare carriers, because each uses its own model, so the insurer that scores your credit most kindly is only found by shopping several.

The bottom line

Does credit affect your car insurance? In most states, yes, and our reading of a real filed rate manual put the swing at roughly 58 percent, from a 1.0000 reference tier down to 0.4163 for the strongest insurance score. It is a separate score from your FICO, built for claim risk, and it is one factor among your record, age, vehicle, and location. A few states ban it entirely. The practical takeaway is to treat your credit as an insurance lever too: pay on time, keep balances low, build history if it is thin, and compare carriers, because each scores credit differently and the one that treats yours best may not be the one you have now.
