Insurers price risk differently

Auto insurance pricing is based on an insurer's underwriting and rating rules. Companies may use different factors, and state law can limit which factors are permitted, so the same person and vehicle can receive different prices from different insurers.

A quote is tied to the information provided and the coverage selected. It is not a universal price for a driver or a guarantee that another quote will be lower.

Common factors to review

Factors can include driving record and claims history, household drivers, vehicle type and repair cost, where the vehicle is kept, annual mileage and use, prior insurance history, selected limits, deductibles, and optional coverages. Discounts may be available when an insurer's rules and state requirements allow them.

  • Driver and household details
  • Vehicle, location, mileage, and use
  • Coverage limits, deductibles, and optional protections
  • Driving, claims, and prior insurance history
  • Discounts or programs the insurer actually offers

How to use the list

Use these factors to make your quote comparisons consistent and to catch incorrect assumptions. Ask the insurer or licensed agent which details affected the quote and whether a change would alter protection as well as price.
