Understanding Your Average Insurance Rate
Auto insurance premiums are calculated by insurers based on a complex algorithm designed to assess risk. While specific formulas vary by company, several common factors significantly influence your rate. Our calculator provides a generalized estimate by considering:
- Estimated Vehicle Value: Higher value vehicles typically cost more to replace or repair, leading to higher premiums.
- Estimated Annual Mileage: Driving more miles increases your exposure to potential accidents, thus increasing your risk and your premium.
- Driver's Age: Younger drivers, particularly those under 25, are statistically more likely to be involved in accidents, leading to higher rates. Rates tend to decrease as drivers gain experience and reach middle age, then may slightly increase again for very elderly drivers.
- Years with Clean Driving Record: A history of accidents or traffic violations (like speeding tickets or DUIs) signals higher risk to insurers. The longer you maintain a clean record, the more you can benefit from lower premiums.
- Coverage Level: The amount and type of coverage you choose directly impacts your premium. Basic liability coverage is the least expensive, while comprehensive and collision coverage, along with lower deductibles, will increase your rate.

Actual insurance rates are determined by individual insurance providers and may differ based on many other factors, including your location, credit score, specific vehicle model, claims history, and the insurer's underwriting guidelines.
