You have a clean driving record. You haven’t had a speeding ticket in years, you’ve never been in an at-fault accident, and you drive a modest, safe vehicle. Yet, when your car insurance renewal notice arrives in the mail, the premium has jumped significantly. You stare at the number, baffled. Why is your rate skyrocketing when your driving habits haven’t changed?
The answer likely lies in a three-digit number that has nothing to do with how well you parallel park: your credit score. For millions of drivers, credit history is the “silent passenger” driving up costs behind the scenes. In fact, in many states, having poor credit can cost you more than having a DUI on your record.
In this guide, we will pull back the curtain on the controversial relationship between credit and car insurance. We will explain exactly how insurers use your financial data against you, calculate how much extra you are paying, and most importantly, show you actionable steps to stop the bleeding and lower your premiums today.
The Hidden Link: Why Insurers Care About Your Credit
It seems counterintuitive. What does paying your credit card bill on time have to do with your likelihood of crashing your car? According to insurance companies, the answer is “everything.”
Insurers are in the business of predicting risk. Decades of actuarial data have shown a strong statistical correlation between a person’s financial stability and their likelihood of filing an insurance claim. Studies from the Federal Trade Commission (FTC) and major insurers suggest that drivers with lower credit scores file claims more frequently and for higher dollar amounts than those with high credit scores.
It is important to understand that insurers are not necessarily worried that you won’t pay your monthly premium. They are worried that you are a higher risk for an accident or a lawsuit. This statistical correlation allows them to justify charging higher rates to offset that perceived risk, a practice known as “risk-based pricing.”
“Insurance Score” vs. FICO Score: What’s the Difference?
When an insurer checks your credit, they aren’t looking at the same FICO score that a mortgage lender or credit card company sees. They are calculating a specific metric called a Credit-Based Insurance Score (CBIS).
While a standard credit score predicts your ability to repay a loan, a CBIS predicts the likelihood that you will experience an insurance loss. Although they are different metrics, they are built from the exact same data found on your credit report. The weighting of factors, however, is slightly different.
The Breakdown of an Insurance Score
Most credit-based insurance scores are calculated using the following weighted factors:
- Payment History (~40%): Do you pay your bills on time? Late payments are the biggest score killers.
- Outstanding Debt (~30%): How much do you owe compared to your credit limits? High utilization signals financial stress.
- Credit History Length (~15%): How long have you been managing credit? Longer is better.
- New Credit Applications (~10%): Have you applied for multiple new cards or loans recently? This indicates risk.
- Credit Mix (~5%): Do you have a healthy mix of revolving credit (cards) and installment loans (mortgages, auto loans)?
Notice what is not included: your income, job title, or net worth. You can be a high earner with a messy payment history and still suffer from a poor insurance score.
The Financial Impact: How Much Extra Are You Paying?
The cost of having a low credit-based insurance score is staggering. In some cases, the penalty for poor credit is steeper than the penalty for reckless driving. Data from major consumer advocacy groups reveals the harsh reality of this pricing model.
On average, a driver with “Poor” credit (typically below 580) will pay double the rate of a driver with “Excellent” credit. Even a drop from “Excellent” to “Average” can result in a premium hike of 20% to 30%. In dollar terms, this often translates to an extra $1,000 to $2,000 per year for the exact same coverage.
Comparison: The “Credit Penalty”
Imagine two neighbors, Alex and Ben. They are both 35 years old, drive 2020 Honda Civics, and have clean driving records.
Alex (Credit Score 780): Pays $1,400 per year.
Ben (Credit Score 560): Pays $2,950 per year.
Ben is effectively paying a “credit tax” of $1,550 annually, despite being just as safe on the road as Alex.

The Legal Landscape: States Where This is Banned
Because the practice of using credit scores for car insurance pricing disproportionately affects low-income drivers, it has become a hot-button political issue. Several states have stepped in to ban or restrict the practice to ensure fair pricing.
As of 2025, if you live in California, Hawaii, or Massachusetts, you are in luck. These states have laws that strictly prohibit insurers from using credit history to set auto insurance rates. In these states, your premium is based solely on your driving record, years of experience, annual mileage, and other non-financial factors.
Other states, like Michigan and Utah, have placed partial restrictions on how the data can be used, such as prohibiting it from being the sole reason for a rate increase or cancellation. However, for the vast majority of Americans, credit remains a primary rating factor.

Real-World Strategy: How to Improve Your Insurance Score
If you live in a state where credit matters, you are not powerless. Improving your credit-based insurance score is the most reliable way to lower your car insurance premium over the long term. Unlike a driving violation, which stays on your record for 3-5 years, credit scores are dynamic and can be improved in a matter of months.
1. Attack Your Credit Utilization
The fastest way to boost your score is to pay down credit card balances. Your “utilization ratio” (balance divided by credit limit) is a massive factor. If your limit is $5,000 and you owe $4,500, your score tanks. Aim to get your utilization below 30%. Even paying down $500 can bump you into a better pricing tier.
2. Dispute “Zombie” Errors
Millions of Americans have errors on their credit reports—old debts that were paid off but still show as “due,” or accounts that don’t belong to them (often from identity theft or mixed files). These are known as “zombie debts.”
Go to AnnualCreditReport.com and pull your reports from Equifax, Experian, and TransUnion. If you see an error, dispute it immediately. Removing a single erroneous collection account can raise your score by 50+ points overnight.
3. Don’t Close Old Accounts
Length of credit history matters. If you finally pay off an old credit card you don’t use anymore, do not close the account. Keeping it open increases your total available credit (lowering utilization) and preserves the age of your credit history. Cut up the physical card if you must, but keep the trade line active.
The “Usage-Based” Loophole
If your credit is poor and you cannot fix it quickly, there is a loophole: Telematics. As we have discussed in other articles, usage-based insurance (UBI) allows insurers to rate you based on how you drive, rather than who you are.
Programs like Progressive’s Snapshot, Allstate’s Drivewise, or State Farm’s Drive Safe & Save rely heavily on real-time driving data (braking, speed, mileage). While credit might still be a factor, demonstrating “Elite” driving safety can often offset the penalty of a poor credit score. If you are a safe driver with bad credit, this is your best immediate option.

Shopping Around With Poor Credit
Not all insurance companies weigh credit equally. Some carriers, often referred to as “non-standard” insurers, specialize in high-risk drivers and may place less emphasis on credit scores than premium carriers.
If you have been with the same major carrier for years and your credit has taken a hit, you are likely being overcharged. Shopping around is critical. When getting quotes, be honest about your credit tier (e.g., “Fair” or “Poor”) to get accurate pricing. You might find a regional carrier that offers a significantly better rate than the national giants.

Conclusion: Take Control of Your Financial Identity
The realization that your credit score is hiking up your car insurance rates is a tough pill to swallow. It feels invasive and unfair, especially if you are a safe driver struggling to get back on your feet financially. But understanding this mechanism is the first step toward defeating it.
You cannot change the insurance industry’s algorithms, but you can change your data. By aggressively managing your credit utilization, disputing report errors, and considering telematics-based policies, you can decouple your driving costs from your financial history. Don’t let a three-digit number dictate your budget—start repairing your score today and watch your premiums fall.
