Understanding Your Car Insurance Premium
Calculating car insurance is a complex process used by underwriters to assess risk. While every company uses a proprietary algorithm, most follow a similar logic involving your personal profile and vehicle data. Use this calculator to see how different variables impact your wallet.
Top Factors That Influence Your Rates
Driver Age: Statistics show that drivers under 25 are involved in more accidents. Premiums typically drop significantly once you reach age 25 and remain stable until age 65.
Vehicle Value: More expensive cars cost more to repair or replace, leading to higher comprehensive and collision costs.
Coverage Level: Liability-only coverage is the legal minimum but doesn't cover your own vehicle. Standard and Premium policies include collision and comprehensive protection.
Deductible: This is the amount you pay out-of-pocket before insurance kicks in. A higher deductible lowers your monthly premium because you are assuming more of the financial risk.
Driving History: A clean record is the best way to keep rates low. Major violations or multiple at-fault accidents can double or triple your premium.

Low Mileage Discount: If you work from home or drive less than 7,500 miles a year, tell your agent.
Defensive Driving Course: Completing an accredited course can earn you a 5-10% discount in many states.
Improve Your Credit: In many regions, insurance companies use credit-based insurance scores to determine risk.
Frequently Asked Questions
Why is my insurance so high?
Common reasons include living in a high-crime zip code, having a low credit score, or driving a vehicle that is expensive to repair.
Does the color of my car matter?
Contrary to popular belief, the color of your car (like red) does not impact your insurance rate. The make, model, and engine size do.
