The countrywide average auto insurance expenditure rose 5.0 percent to $1,056.55 in 2018 from $1,006.33 in 2017 according to the National Association of Insurance Commissioners. In 2018 (the latest data available), the average expenditure was highest in Louisiana ($1,545.82) followed by Michigan ($1,469.73), and the District of Columbia ($1,429.43).

To calculate average expenditures the National Association of Insurance Commissioners (NAIC) assumes that all insured vehicles carry liability coverage but not necessarily collision or comprehensive coverage. The average expenditure measures what consumers actually spend for insurance on each vehicle. It does not equal the sum of liability, collision and comprehensive expenditures because not all policyholders purchase all three coverages. The average expenditure measures what consumers actually spend for insurance.

AAA’s 2020 Your Driving Costs study found that the average cost to own and operate a 2020 model vehicle was $9,561 in 2020. The average insurance cost for medium sedans was $1,245, down from $1,251 in 2019. AAA insurance cost estimates are based on a full coverage policy for a driver who is under 65 years of age, has more than six years of driving experience, has had no accidents and lives in a suburban/urban location. The coverage is for a policy with $100,000/$300,000 personal liability, $25,000 medical, $100,000 property and $25,000/$50,000 uninsured/underinsured motorist coverage, with a $500 deductible for collision and comprehensive claims. These figures are not comparable with the National Association of Insurance Commissioners’ auto expenditures data, below.
