Big vs. small insurance companies

The trade-off between large insurance companies and small ones typically involves giving up competitive rates for an improved customer experience.

  • When using a small insurance company for your auto insurance, you’ll likely communicate exclusively with one insurance agent.
  • While you might lose a personal connection when selecting a major insurer, the largest companies tend to have more financial stability. In fact, these carriers underwrite and pay out billions of dollars per year, and still often leverage their resources to offer drivers lower insurance rates.

You may worry about solvency if you choose a policy from a smaller company. If you manage to find a small insurer with a base level of financial stability that you’re comfortable with, consider how much in price you’re willing to pay for better service. If you value great service, you might prefer a small insurance company.

Below, we compared the ten largest auto insurance companies according to their financial strength rating by A.M. Best.

RatingInsurers
A++/SuperiorState Farm, Geico, USAA
A+/SuperiorProgressive, Allstate, Nationwide
A/ExcellentLiberty Mutual, Farmers, Travelers, American Family

Another consideration is availability, coverage options and discounts. While you’re likely to have a more personalized experience with a small insurance company, it may not have the availability, benefits and discounts that large insurance companies do. And the major insurance companies often have representatives that are still available to speak with policyholders 24/7.



Mutual vs. Stock insurance companies

The main difference between mutual and stock insurance companies is the ownership configuration—stock insurance companies are privately or publicly owned companies that offer voting rights to stockholders. Mutual insurance companies, however, are owned by their policyholders.

Since stockholders benefit from the stock’s appreciation, people argue that the short-term interests of investors don’t always align with the long-term interest of the company. Many feel that mutual insurance companies are better because the policyholders’ interests align well with what’s best for the company, specifically lowering insurance rates and paying out dividends to attract more customers.

Below, we list the top ten auto insurance companies by type, excluding USAA, which is an insurance exchange for military personnel.

Methodology

Market share and direct written premium information for private auto insurance was gathered from the National Association of Insurance Commissioners (NAIC) and S&P Global, a financial data resource for the insurance industry.

We collected minimum coverage auto insurance quotes across 50 states and Washington, D.C. Our base driver was a 30-year-old male who drove a 2015 Honda Civic EX, and quotes were drawn from all available ZIP codes in each state.

ValuePenguin's analysis used insurance rate data from Quadrant Information Services. These rates were publicly sourced from insurer filings and should be used for comparative purposes only — your own quotes may be different.
