A practical look at the information insurers may use to price auto coverage—and why your quote can differ from one company to another.

Why auto insurance prices differ

Insurance pricing reflects an insurer's estimate of future claim risk and cost. Insurers do not necessarily use or weigh every permitted factor in the same way, which is why prices can vary even when the requested coverage is similar.

Driving history

Accidents, violations and other driving-history information may affect underwriting or rating, subject to state law and the insurer's rules.

Where the vehicle is kept

Location can matter because claim frequency, theft, repair costs, weather exposure and other loss patterns vary geographically.

Your vehicle

Vehicle value, repair costs, safety features, theft experience and other vehicle characteristics can influence the expected cost of claims.

How the vehicle is used

Annual mileage, commuting and other use information can be relevant to rating or eligibility for certain programs.

Coverage, limits and deductibles

More coverage or higher limits generally changes the insurer's potential obligation. Lower physical-damage deductibles generally shift more of a covered loss to the insurer.

Household and policy factors

Household drivers, prior insurance information, bundling, discounts and other permitted variables may also affect the final premium.

Shopping takeaway: Compare equivalent coverage and provide the same information to each insurer. Otherwise you may be comparing different products rather than different prices.
