Driving Record and Claims History
Accidents, traffic violations, and past claims signal higher risk, so insurers assign higher rates to drivers with more incidents.
Vehicle Make, Model, and Age
Cars with higher repair costs, powerful engines, or advanced safety features affect premiums differently; newer, safer models often qualify for discounts.
Personal Demographics
Age, gender, marital status, and credit score are used to predict liability, with younger drivers and those with lower credit typically paying more.
Geographic Location
Areas with higher accident frequencies, theft rates, or severe weather raise the cost of coverage compared to low‑risk regions.
Coverage Choices and Deductibles
Higher liability limits, comprehensive and collision coverage, and low deductibles increase the premium, while higher deductibles and minimal coverage lower it.
Additional Factors
Usage patterns (annual mileage), policy bundling, and discounts for safety devices or good driver programs can further adjust the price.
