Six Major Factors that Influence Auto Insurance Rates

No two car insurance rates are the same. From driver to driver, several factors will change how much a policyholder pays for even the same coverage. Here we review the six main components that go into the auto insurance rates recipe.

1. How Much You Drive

Car insurance companies measure rates based on risk. The more miles you drive, the higher the risk you will be in a car accident. You’ll pay more if you drive more. If, on the other hand, you drive fewer than 10,000 miles annually, you may qualify for a low mileage discount from your auto insurer. People who carpool often receive discounts because they drive less frequently.

2. Your Driving History

Being a good driver matters to car insurers. Many insurance companies offer special discounts to good drivers. If you have had a series of accidents or traffic violations, you may pay more for your premium. If you have not carried car insurance in several years, you may also pay more for your policy.
