It feels like a punch to the gut: you haven’t had a speeding ticket in 10 years, you’ve never caused an accident, but your car insurance bill is higher than your neighbor who just crashed his car last month. The hidden culprit? Your credit score.
Quick Answer: In most U.S. states, insurers use a specialized “insurance credit score” to set your rates. A driver with poor credit (below 600) will pay up to 100% more for the exact same coverage as a driver with excellent credit—even with a flawless driving record. Improving your credit score by even 50 points can save you hundreds of dollars a year.
This practice is perfectly legal and incredibly common. If you don’t understand how insurance credit scores work, you are leaving money on the table. Here is exactly how your credit dictates your premium, which states ban the practice, and the fastest ways to fix your score to get a lower rate.
Why Do Car Insurance Companies Care About Credit?
Insurers don’t look at your credit score because they are lending you money. They use a derivative called an insurance-based credit score because decades of statistical data show a direct correlation: people with lower credit scores file more claims, and those claims tend to be more expensive.
According to studies backed by the Federal Trade Commission (FTC), drivers with the worst credit scores file 40% more claims than drivers with the best scores. Insurers argue that financial responsibility behind the wheel mirrors financial responsibility in the bank. Critics argue it unfairly punishes lower-income Americans, but for now, the math dictates the market.
States Where Credit Scores CANNOT Be Used
Lawmakers in a few states agree that tying credit to driving risk is unfair. If you live in one of these states, your credit score will not affect your car insurance rate:
- California – Completely banned since 1988 (Proposition 103).
- Hawaii – Completely banned.
- Massachusetts – Completely banned.
- Michigan – Banned as a primary rating factor (though restrictions are complex).
- Washington – Recently passed strict limitations limiting its use.
If you live in any other state, your insurer is legally allowed to pull your credit to calculate your premium.
The Shocking Numbers: How Much Credit Actually Costs You
Based on 2026 rate data from Quadrant Information Services, look at how a 40-year-old driver with a clean record and a standard sedan is treated based purely on credit:
- Excellent Credit (750+): $1,450 / year
- Good Credit (700–749): $1,650 / year (+14%)
- Fair Credit (600–699): $2,100 / year (+45%)
- Poor Credit (Below 600): $2,900 / year (+100%)
That is a staggering $1,450 difference per year for the exact same car and the exact same driving history. Over a few years, having bad credit will cost you more than the actual value of a used car, all paid straight to your insurance company.

Not All Insurers Punish Bad Credit Equally
This is where you can exploit the market. Insurance companies weigh credit differently in their algorithms:
- Progressive & Geico: Tend to weight credit scores very heavily. If you have great credit, these are often the cheapest. If you have poor credit, they will penalize you ruthlessly.
- State Farm: Weighs credit moderately, but factors in loyalty and agent relationships, which can soften the blow.
- Farmers: Historically places slightly less emphasis on credit than Geico or Progressive, making them a good fallback for fair/poor credit drivers.
- Non-Standard Carriers (The General, SafeAuto): Because they already deal with high-risk drivers (DUIs, SR-22s), credit matters slightly less to them, though their base rates are much higher.
The takeaway: If your credit drops, you cannot just stay with the same company. You must shop around, because the company that gave you the best rate at a 750 credit score might be the worst option at a 620 score.
How to Fix Your Insurance Credit Score Fast
An insurance credit score uses the same data as your FICO score, but weights it slightly differently (they care less about your total available credit and more about your payment history and length of credit). Here is how to raise it quickly:
- Never miss a payment again. A single 30-day late payment can drop your score by 60-100 points. Set up autopay for the minimums on all cards.
- Lower your credit utilization. If you have a $5,000 limit and owe $4,000, you are maxed out. Pay it down to under 30% ($1,500) and your score will jump within 30 days.
- Don’t close old credit cards. A card you opened in 1998 with a $0 balance is gold for your credit age. Cutting it up lowers your average account age and hurts your score.
- Dispute errors on your reports. Go to AnnualCreditReport.com (the official, free, government-mandated site). Roughly 20% of consumers have errors on their reports that are dragging their scores down.
Frequently Asked Questions
Does getting a car insurance quote hurt my credit score?
No. When an insurer checks your credit to give you a quote, it generates a “soft inquiry.” Soft inquiries do not affect your credit score at all. Only “hard inquiries” (like applying for a new credit card or car loan) lower your score by a few points.
What credit score do insurance companies use?
They usually do not use your standard FICO 8 score that mortgage lenders use. Most auto insurers use proprietary scores generated by companies like LexisNexis (AutoScore) or FICO Auto Score 8. These models heavily penalize recent late payments and collection accounts.
Can I get car insurance with no credit history at all?
Yes. If you are a new immigrant, a young driver, or simply live a cash-only lifestyle, you have a “thin file.” Insurers cannot legally deny you coverage just because you have no credit. By law, they must assign you a “neutral” score that falls somewhere in the middle—meaning you won’t get the best rates, but you won’t be penalized like someone with bad credit. Alternatively, you can opt for telematics (usage-based) insurance, which bases your rate entirely on your driving habits rather than your credit.
Don’t Let Your Credit Score Dictate Your Premium
