Insurance companies: Big or small?

In order to improve customer service, large insurance companies will often trade off with smaller ones.

  • You will likely only communicate with one agent when you use a small company to insure your auto.
  • Although you may lose your personal connection to a major insurer when choosing one, the biggest companies have greater financial stability. These carriers actually underwrite and pay billions of dollars annually and often leverage their resources in order to offer lower rates for drivers.

If you select a policy from an inexperienced company, it may be necessary to worry about your financial stability. You can find a small insurance company that offers a good level of financial stability. Now think about how much you are willing to pay to get better service. A small company might be better for you if you are looking for great service.

Below is a comparison of the top 10 auto insurance companies based on AM Best’s financial strength rating.

Rating Insurers
A++/Superior State Farm, Geico, USAA
A+/Superior Progressive, Allstate Nationwide
A/Excellent Liberty Mutual, Farmers, Travelers, American Family

Also, consider the availability of coverage options and discounts. Although you may have a more personal experience with small insurance companies, they might not offer the same benefits or discounts as large insurance companies. The representatives of the largest and most well-known insurance companies are often available 24/7 to assist policyholders.

Insurance companies that offer mutual vs. stock coverage

The most important difference between stock and mutual insurance companies is their ownership structure. Stock insurance companies can be privately-owned or publicly-owned, and offer stockholders voting rights. However, mutual insurance companies are owned by their policyholders.

Stockholders are able to benefit from stock appreciation. However, some people feel that investors’ short-term interests may not always be in the best interest of the company. Mutual insurance companies are preferred because policyholders have a strong interest in the company’s success, including lowering insurance rates and exchanging dividends to increase customer numbers.

Below is a list of the 10 largest auto insurers by type.

Insurance companies that offer mutual insurance Stock insurance companies
State Farm Geico
Liberty Mutual Allstate
