The primary factors affecting car insurance rates are your driving record, age, location, the type of vehicle you drive, and your credit-based insurance score. Insurers use complex algorithms to assess risk, and a poor rating in any of these areas can significantly increase your premium.
Your personal history is the most direct factor. A clean driving record with no accidents or traffic violations signals to insurers that you are a low-risk driver. Conversely, a history of at-fault accidents, speeding tickets, or DUI convictions will cause your rates to spike. Your age is another major component; statistically, drivers under 25 and over 75 are involved in more accidents, leading to higher premiums.
Where you live matters immensely. Insurers analyze your ZIP code for data on traffic density, crime rates (specifically vehicle theft and vandalism), and even the frequency of weather-related claims. Urban areas typically have higher rates than rural ones due to these risks. The car you choose is equally important. Insurers calculate premiums based on the vehicle's loss history, which includes the cost of repairs, its likelihood of being stolen, and overall safety ratings. A high-performance sports car will always cost more to insure than a family-friendly minivan.
Finally, in most states, your credit history is a significant factor. Data shows a correlation between creditworthiness and the likelihood of filing a claim. Maintaining a good credit score can lead to more favorable insurance rates.

| Vehicle Type | Sports Car (e.g., Ford Mustang) | 25-50% higher than average | High theft rates and repair costs |
| Minivan (e.g., Honda Odyssey) | 10-15% lower than average | Excellent safety and low repair costs |
| Location | Urban ZIP Code (e.g., Detroit, MI) | 50-70% higher than national avg. | High population density and claim frequency |
| Rural ZIP Code (e.g., rural Nebraska) | 20-30% lower than national avg. | Less traffic and lower crime rates |
| Coverage Level | State Minimum vs. Full Coverage | Difference of $500-$1,500/year | Full coverage includes comprehensive/collision |
