10 largest auto insurance companies in the U.S.

If you’ve seen a car insurance commercial, chances are it’s for one of the largest auto insurance companies in the U.S. These insurers not only hold the largest percentage of market share nationwide but are generally the most well-known auto insurance companies in the country.

The table below highlights the 2024 market share of the largest auto insurance companies in the U.S., according to the National Association of Insurance Commissioners (NAIC); 2024 is the most recently available data.

A quick snapshot of the top 10 car insurers

Allstate

Allstate makes it easy to get an instant rate quote and file a claim online, without ever calling an agent. The company also offers a highly rated mobile app for iOS and Android devices, where you can submit claims, pay your bill, download your ID cards, request roadside assistance and access the Drivewise safe driver rewards program.

American Family

More than 50% of American Family customers say they would recommend the company. It’s one of the best car insurance companies for discounts, with various savings for teen drivers, young volunteers, generational policyholders, driving under a certain number of miles per year, switching from a competitor company and more.

Auto Club Group of Southern California (AAA)

AAA roadside assistance and travel discounts have stood out in the insurance industry for decades. While the Automobile Club Group of Southern California (AAA) is an exclusive car insurance provider, not all members are policyholders. AAA offers a variety of coverage options, from state-minimum liability insurance to full coverage, and add-ons such as GAP insurance and modified vehicle insurance. It also offers policy options for RVs and motorcycles.

Farmers

In addition to its low rates, Farmers stands out for its impressive lineup of endorsement policies. You can increase your protection with spare parts coverage, a glass deductible buyback, accident forgiveness, guaranteed value coverage, and others. You can also report a car insurance claim online or through the Farmers mobile app.

Geico

Geico has bare-bones car insurance coverage, but it offers some of the best auto insurance discounts in the industry. You’ll find savings for federal employees, military personnel, emergency deployment, affinity groups and more. Geico also stands out for its low premiums, even if you have a poor credit score or bad driving record.

Liberty Mutual

Liberty Mutual offers a wide range of car insurance options, including liability and full coverage. Policyholders can take advantage of discounts for maintaining a clean record and insuring multiple cars on the same policy. RightTrack, its usage-based insurance (UBI) program, offers savings of up to 30% for good drivers.

Progressive

Progressive is a great insurance provider if you’re looking for cheap rates and generous discounts. However, the company offers some of the best online tools and resources. You can use the Name Your Price Tool to build a policy that fits your budget and use the rate comparison tool to see how Progressive’s prices stack up against competitors.

State Farm

State Farm is the biggest car insurance company in the country and it’s rated the best overall. State Farm is known for offering affordable rates and great customer service, plus policyholders are generally satisfied with the company’s claim handling. We also like that State Farm offers a variety of discounts, including savings for teen drivers.

Travelers

Travelers has excellent financial strength with an A++ rating from AM Best and affordable rates. The company stands out for its add-on policies, like rideshare coverage and accident forgiveness, and an efficient claims-handling process. You can start a new claim online, track the status of existing claims and even find a repair shop in your area.

USAA

USAA only offers membership to active and retired military personnel and their immediate families. If you qualify, you can buy car insurance from USAA for rates that are notably cheaper than those of other large carriers.

Important factors to consider when choosing an auto insurance provider

While it may seem that all car insurance companies are virtually the same, it’s not necessarily true.

Most of the largest car insurance companies have hundreds of years of long-standing history providing drivers affordable coverage to protect their assets and property. Over time, claims and inflation have increased, spiking rates and creating a more competitive landscape. It’s easy to think all insurers have high rates, but comparison shopping will show you that’s not the case.

So, when it comes to selecting a car insurance company, what should you consider? Below are some of the most important factors to keep in mind when you’re shopping around for your policy.

• Bunding and discounts: If you want to save on your policy, consider a car insurance company’s bundling and discount options. You could potentially save hundreds by bundling your home and auto policies with a good driver and low-mileage discounts. Also, paying your bill automatically each month can also save you! Some of the best car insurance companies will ensure they have great bundling and driver discount programs.
• Claims: When shopping around, ask your potential insurance agent about their claims process. It helps to do some review reading on this topic, too. Should you be involved in an accident or moving violation, you’re going to want an insurer who has a strong, smooth and clear claims process in place. 
• Coverage: Your coverage is the single most important factor to consider when shopping car insurance companies. It helps to list what your must-haves and nice-to-haves are when it comes to coverage and let your potential insurance agent guide you through selecting what options work best for your needs (and pocketbook). This process can be a good indicator of the type of company you will have protecting you and your property.
• Customer service: What do you consider the best customer service? This could range from addressing your needs efficiently and thoroughly assessing your concerns to helping you navigate an online experience or changing your policy. Determine what you value when it comes to customer service and ask your potential insurer how they handle certain scenarios. It could also help to do your homework and read online reviews or the Better Business Bureau’s accredited insurance companies’ profiles to learn more about a car insurance company’s customer service.
• Financial ratings: Understanding where a car insurance company stands when it comes to financial stability and claims-paying ability is essential. This indicates how likely they are to financially survive, especially after a major event. You can review companies on AM Best to learn more about how they rank.
• Premiums: The lowest rate is the best one, right? Not exactly. While most auto insurance shoppers are price comparing, it shouldn’t be the driving factor when deciding on a car insurance company. Sure, it might appear that you’re saving $70 a month with one insurer over another, but when you compare other factors — customer service, bundling options, discounts — you could find that the savings aren’t all they’re cracked up to be.  

Benefits of large vs. small insurance companies

Have you ever driven past an insurance company and not recognized its name? Chances are that was a smaller insurance provider in your city. While most drivers opt for a policy with a larger, well-known auto insurance provider, there are benefits to working with a smaller insurer. How do you decide which one is best for your needs?

“A national insurer may have more personnel to handle claims and customer service issues, especially after a major catastrophe like a hurricane or wildfire,” says Mark Friedlander, director of corporate communications for the Insurance Information Institute (Triple-I), an industry research and outreach organization.

“However, many regional insurers are highly rated for their claims and customer service. A distinguishing factor to consider is whether your insurer has a robust mobile app where you can easily manage your policy and file claims.”

Explore some of the pros and cons of working with larger and smaller insurance companies below.

Pros of larger auto insurance companies

In general, car insurance policies that major insurance companies underwrite tend to be less expensive. Because large insurers write millions of policies each year, they can afford to price their policies more competitively.

“The best benefit of larger insurance companies is that they often have a larger pool of money to offset risk, which means they should be able to maintain more stable premiums,” says Shane Page, president of Piedmont Insurance Associates in North Carolina. “If a small company sustains catastrophic losses from a storm in a given state, it will impact their future rates much more drastically than the large companies who sustain the same losses.”

Additionally, the biggest insurance companies in the U.S. often have more coverage options. A large provider will likely have those policies if you want to customize your policy with endorsements or need specialty coverage like rideshare insurance.

Cons of larger auto insurance companies

Having a policy with a larger auto insurance company may give you peace of mind that it’s established, reputable and well-equipped to deal with any situation you may face on the road, but sometimes, that’s the problem. Larger auto insurance companies are used to handling hundreds of claims and policies, which may make you feel like another cog in a big wheel.

Throughout 2024, rising inflation rates and supply chain shortages created a backlog at auto shops nationwide, which also contributed to spiking insurance rates — many of which hit the larger auto insurance companies the hardest. These situations rippled into decreased customer service satisfaction rates and rate increases led many to start price shopping at companies outside of the top 10 largest car insurance companies.  

Pros of smaller car insurance companies

On the other hand, smaller local insurance providers usually have better customer service than large providers. 

“Small companies are often much more personal and locally engaged, as you would expect,” Page says. “Plus, there is usually more latitude for underwriting decisions, and being a loyal customer can pay off.”

So, choose a local insurance company if you prefer to work with an agent in person and value a customized experience. 

Cons of smaller auto insurance companies

You may feel personally more taken care of with a smaller car insurance company, but there can be some drawbacks.

Since you’re not working with an insurer who can employ hundreds or thousands of employees, when you have a billing, coverage or online issue past closing time, you’re likely out of luck until the next business day.

While customer service concerns can be more inconvenient than a deal breaker, other issues — like finding a specific type of coverage or a much cheaper rate — could be a much bigger concern when you’re with a smaller auto insurance company.

Final thoughts

Before shopping for a policy, take a moment to determine what you need and your budget. Then, highlight what is most important to you when it comes to who you’re doing business with.

Does exceptional and personal customer service support rank high on your list? Do you want an insurance company that has lots of perks? What does “affordable insurance” mean to you? Once you decide what you need, shop around and mix it up — you never know where your best rate, claims process and discount options could be found.
