How Your Credit Score Affects Your Insurance Rates (and How to Fix It)
Most consumers understand that a good credit score is the key to securing a low-interest mortgage or a competitive credit card. However, many are surprised to learn that their credit history can have a larger impact on their car and home insurance premiums than their driving record or the age of their roof.
In the insurance industry, this is known as a Credit-Based Insurance Score (CBIS). While it shares data points with your traditional FICO score, its purpose and application are entirely different. This guide explains the technical correlation between credit and risk and provides a roadmap for improving your score to secure lower rates.
1. What is a Credit-Based Insurance Score (CBIS)?
A Credit-Based Insurance Score is a numerical ranking based on specific items in your credit report. It is not used to determine your "creditworthiness" in terms of debt capacity; instead, it is used to predict the likelihood of you filing a claim that will cost the insurance company money.
The Statistical Correlation
Actuarial data collected over decades has shown a remarkably consistent trend: individuals who manage their finances responsibly are statistically less likely to be involved in accidents or file home insurance claims. While it may seem unrelated to driving a car, insurers view financial responsibility as an indicator of overall risk-avoidance behavior.

While a traditional lender looks at your "Debt-to-Income" ratio and total debt, an insurance score focuses more heavily on:
- Payment History: Do you pay bills on time?
- Outstanding Debt: How much of your available credit are you using?
- Credit History Length: How long have you been managing credit?
- Credit Mix: Do you have experience with different types of accounts?
2. The Financial Impact: How Much More Are You Paying?
The difference in premiums between a "Poor" and "Excellent" credit-based insurance score can be staggering. In 2026, depending on the state and the carrier, a driver with poor credit may pay 50% to 100% more for the exact same coverage as a driver with excellent credit.
Impact on Auto Insurance
For a standard auto policy, a low credit score can result in a "surcharge" that outweighs the impact of a minor speeding ticket or an at-fault accident. In some cases, moving from the "Fair" category to "Good" can save a driver between 200 and 500 dollars annually.
Impact on Homeowners Insurance
Insurers use credit scores to predict the likelihood of "nuisance claims"—small claims for minor damage that are costly for the insurer to process. Homeowners with higher credit scores are viewed as being more likely to self-fund minor repairs, leading to lower premiums.

It is important to note that the use of credit in insurance is not legal everywhere. As of 2026, several jurisdictions have banned or strictly limited the use of credit scores for insurance underwriting:
- California, Hawaii, and Massachusetts: These states prohibit the use of credit scores in determining auto insurance rates.
- Maryland and Michigan: There are specific restrictions regarding how credit can be used for homeowners and auto insurance respectively.
If you live in a state where credit is a factor, the law typically requires the insurer to notify you if your credit score was the reason for an "adverse action," such as a rate increase or a denial of coverage.
4. How to Fix Your Credit to Lower Your Insurance Rates
If your insurance rates are high due to your credit score, the good news is that insurance scores are dynamic. As your credit improves, your premiums can drop during your next policy renewal. Here is how to fix it:
Step 1: Correct Errors on Your Credit Report
Data inaccuracies are common. Obtain a free copy of your credit report and look for accounts that do not belong to you, incorrect payment statuses, or duplicated debts. Disputing and removing a single late payment that was recorded in error can result in an immediate score boost.

Your "utilization" is the amount of credit you are using compared to your total limits. Aim to keep this under 30%, though 10% is ideal for the highest insurance scores. Paying down high-interest credit card balances is the fastest way to improve this metric.
Step 3: Automate Your Payments
Payment history is the most significant factor in a CBIS. A single 30-day late payment can stay on your report for seven years and negatively impact your insurance rates for the duration. Set up autopay for the minimum balance on all accounts to ensure you never miss a deadline.
Step 4: Avoid Opening New Accounts Frequently
Every time you apply for a new credit card or loan, a "hard inquiry" is recorded. Multiple inquiries in a short period can signal financial instability to an insurance algorithm. Only apply for new credit when absolutely necessary.
Step 5: Keep Old Accounts Open
The "age of credit" is a key factor. Even if you no longer use a specific credit card, keeping the account open increases the average age of your credit history and your total available credit, both of which improve your score.

Improving a credit score takes time. If you are currently facing high premiums, consider these immediate alternatives:
- Shop with Non-Credit-Based Insurers: Some smaller or specialized insurers place less weight on credit and more on driving history.
- Usage-Based Insurance (Telematics): If your credit is poor but you are a safe driver, programs that track your actual driving (braking, speed, mileage) can often override the negative impact of your credit score.
- Increase Your Deductible: This lowers your premium immediately while you work on the long-term goal of improving your credit.
