Finding the right car insurance company for you

Don’t forget about the smaller insurance companies. When shopping for car insurance, it's smart to consider a wide range of choices, from our list of the nation's biggest car insurance companies to smaller, regional insurers that may be a better fit for you.

Look at the big picture of customer satisfaction, claims service and price, and use NerdWallet’s car insurance comparison tool to help you compare rates.

Collect some basic information. This includes the driving history of everyone who will be on the policy, as well as facts about your car, such as safety features and estimated annual miles driven.

Determine which types of coverage you need. For example, do you want only the bare minimum insurance that your state requires, or do you want full coverage insurance, which offers greater financial protection on the road. Check that each company you’re considering has the options you want.

Compare apples to apples. When comparing rates among insurers, make sure each is offering the same coverage limits and deductibles. You may not want to make your decision based on price alone. Look at how many consumer complaints each company has, as a high number of complaints could be a red flag about the quality of service you'll receive.

Depending on which company you choose, you may be able to buy insurance online, over the phone or through an agent. For more guidance, see how to buy car insurance.

Methodology

Insurer complaints methodology

NerdWallet examined complaints received by state insurance regulators and reported to the National Association of Insurance Commissioners in 2020-2022. To assess how insurers compare to one another, the NAIC calculates a complaint index each year for each subsidiary, measuring its share of total complaints relative to its size, or share of total premiums in the industry. To evaluate a company’s complaint history, NerdWallet calculated a similar index for each insurer, weighted by market shares of each subsidiary, over the three-year period. NerdWallet conducts its data analysis and reaches conclusions independently and without the endorsement of the NAIC. Ratios are determined separately for auto, home (including renters and condo) and life insurance.

Auto insurance ratings methodology

NerdWallet’s auto insurance ratings reward companies for customer-first features and practices. Ratings are based on weighted averages of scores in several categories, including financial strength, consumer complaints and discounts. Our “ease of use” category looks at factors such as website transparency and how easy it is to file a claim. Using our editorial discretion, we also consider customer satisfaction surveys. These ratings are a guide, but we encourage you to shop around and compare several insurance quotes to find the best rate for you. NerdWallet does not receive compensation for any reviews. Read our editorial guidelines and full ratings methodology for auto insurance.

Here’s how we evaluated each car insurance company in 2024 and the weights we placed on each category:

  • Financial strength (30%).

  • Consumer complaints (30%).

  • Ease of use (20%).

  • Affordability (20%).

The best auto insurers excel at all of these categories. They provide the information people need to make a purchase without any surprises along the way. They offer insurance at a fair price and provide more than one way to buy and manage a policy. They're financially strong and able to keep their customers happy throughout the relationship.
