Does Your Credit Score Affect Your Car Insurance Rates?

The short answer: In most states, yes. Auto insurers use a credit-based insurance score, related to but not the same as your regular credit score, as one factor in setting your premium, so weaker credit often leads to higher rates. A handful of states restrict or ban the practice. Improving your credit over time can meaningfully lower what you pay to insure a car.

This guide explains how credit ties into insurance rates, why insurers use it, and where it does not apply.

How credit ties into insurance

Insurers in most states use a credit-based insurance score when pricing a policy. It draws on your credit report but is calculated differently from a lending score, and it exists because studies have linked certain credit patterns to how likely someone is to file claims. The result is that two similar drivers can pay different premiums largely because of their credit.

Why insurers use it

From the insurer’s point of view, the credit-based insurance score is a statistical predictor of risk, one input alongside your driving record, vehicle, location, and coverage. It is not a judgment of character; it is an actuarial tool. Still, it means your credit habits quietly affect a bill that has nothing to do with borrowing.

Where it does not apply, and what to do

A few states restrict or prohibit using credit in auto insurance pricing, so it may not affect you at all depending on where you live. Everywhere else, the same fundamentals that build a good credit score, on-time payments and low utilization, gradually improve your insurance score too. So improving your credit can pay off twice, in lower borrowing costs and lower premiums, and it is worth shopping insurers, since they weigh credit differently.

The bottom line
  • Most states let insurers use a credit-based insurance score.
  • Weaker credit often means higher premiums.
  • It is related to but not identical to your regular credit score.
  • A few states restrict or ban the practice.
  • Improving your credit can lower your rates over time.

Frequently asked questions

Does credit affect car insurance rates?
In most states, yes. Insurers use a credit-based insurance score as one factor in your premium, so weaker credit often means higher rates. A few states restrict or ban it.
Is the insurance credit score the same as my regular credit score?
No. A credit-based insurance score draws on your credit report but is calculated differently and predicts claim risk rather than lending risk, though good credit habits help both.
Can improving my credit lower my car insurance?
In states that use credit, yes. The same habits that raise your credit score, paying on time and keeping utilization low, improve your insurance score and can reduce premiums over time.
