Unsurprisingly, the 10 largest car insurance companies in terms of market share — the percentage of total industry sales each insurer has — feature a lot of familiar names. The top three car insurance companies based on market share — State Farm, Progressive, and GEICO — are some of the most well-known brands in the country.

Most of us are familiar with the GEICO gecko, Jake from State Farm, and Flo from Progressive, so it’s no surprise to see these companies top the list. In fact, the trio has snatched up nearly half of the total auto insurance market between them. But that doesn’t mean there aren’t plenty of other great options out there.

The following table includes the 10 largest auto insurance companies in the U.S. and their corresponding market share, according to data from the National Association of Insurance Commissioners (NAIC).

Insurance Company Market Share Average Monthly Rate
State Farm 17% $86
Progressive 14% $109
GEICO 14% $70
Allstate 11% $155
USAA 6% $62
Liberty Mutual 5% $100
Farmers 5% $154
Travelers 2% $128
American Family 2% $94
Nationwide 2% $123

State Farm leads the industry with a whopping 17% market share, but Progressive, Allstate, and GEICO each claim at least 1 in 10 insurance shoppers. USAA, Liberty Mutual, and Farmers all boast at least 5% of the market as well, with several other big names rounding out the top 10.

But which one is right for you? Let’s take a closer look at each company.

1. State Farm rating: 4.3 out of 5

Average monthly rate: $86

State Farm’s combination of discounts, low rates for good drivers, and highly rated customer service has led to the insurer writing the most auto insurance policies of any company in the U.S.

State Farm also boasts outstanding claims service teams and offers a variety of typical car insurance coverage options. And with above-average customer satisfaction scores in J.D. Power’s most recent auto insurance study and some of the lowest rates in the industry (even for drivers with a DUI), State Farm is a great choice for drivers looking for robust coverage at a great price.


  • Above-average J.D. Power customer satisfaction ratings
  • Wide variety of available discounts
  • 24/7 claims service


  • Higher-than-average number of customer complaints
  • Relatively limited coverage options
  • Mixed customer reviews
  • Gap insurance not available

2. Progressive rating: 4.2 out of 5

Average monthly rate: $109

Like a number of national car insurance companies, Progressive offers 24/7 service, a convenient mobile app, and competitive rates for its customers—including high-risk drivers. You can also enjoy bundling discounts for insuring multiple products — such as auto and home insurance — with Progressive. But you should be prepared for potential rate increases and issues with the Snapshot app, based on recent customer reviews.


  • Potential savings of 30% with Snapshot program
  • Outstanding discount offerings
  • 24/7 customer and claims service


  • Potential rate hikes
  • Unclear loyalty program requirements
  • Reported issues with Snapshot mobile app

3. GEICO rating: 4.65 out of 5

Average monthly rate: $70

GEICO is well-known for its low rates, which makes it a popular choice for drivers who prioritize cost when shopping for car insurance. The company also provides a fast and easy quote process — both online or over the phone — and a variety of discounts to help you save.

The company doesn’t have a lot of local insurance agents, but GEICO’s mobile app and website make it easy to manage your car insurance policy online.


  • Competitive rates for high-risk drivers
  • Wide variety of insurance products
  • Highly rated mobile app


  • Below-average customer service scores
  • Limited number of car insurance discounts
  • Gap insurance not available

4. Allstate rating: 4.2 out of 5

Average monthly rate: $155

Allstate is a well-known car insurance brand, potentially due to its reputation for insuring drivers with varying driving and insurance histories. High-risk drivers can typically get an affordable Allstate policy, but so can drivers with clean records. The company covers a range of other vehicles and products, too. Allstate has a solid online presence, but still boasts a large network of local insurance agents who can offer personalized support to those who need it.


  • Wide variety of available coverage options
  • Available in all 50 states
  • Investment and retirement products also offered


  • High number of customer service complaints
  • Reportedly inefficient claims process
  • Potential issues with Drivewise and Milewise apps

5. USAA rating: Not yet rated

Average monthly rate: $62

USAA offers what many drivers are looking for in a car insurance company — competitive rates and plentiful discounts. But you must be affiliated with the military to become a USAA member and be eligible for coverage.

Only military members, veterans, and their families are eligible for USAA, but, if you qualify, you can expect competitive rates and expansive coverage options.


  • Extremely low rates
  • Numerous available discounts
  • Potential savings of 30% with SafePilot


  • Only available to active military members, veterans, and their families
  • 24/7 customer service not available
  • Gap insurance not available

6. Liberty Mutual rating: 3.95 out of 5

Average monthly rate: $100

Liberty Mutual’s competitive car insurance rates and wide variety of discounts have helped make it one of the largest car insurance companies in the industry. The insurer offers standard car insurance options as well as less traditional ones, such as antique car insurance policies and coverage in Mexico.

The company also covers several other vehicle coverages and insurance products, making it ideal for someone who wants to protect all their belongings with one company.


  • Potential savings with RightTrack
  • Competitive rates
  • Large number of available discounts


  • Reportedly long, frustrating claims process
  • Technical issues with quote process
  • Mixed customer service reviews

7. Farmers rating: 4.1 out of 5

Average monthly rate: $154

Farmers’ local agent model gives you the best of both worlds — the personalized touch of a small insurance company with the benefits of a larger insurer, such as great rates and plentiful coverage options. Farmers also offers a variety of car insurance discounts and savings programs, such as its telematics program, Signal. The downside is the insurer’s rates and customer service ratings don’t stack up well with the other companies on this list.


  • Multiple car insurance coverage options available
  • Expansive local agent network
  • Available bundling opportunities


  • Above-average premiums
  • Below-average customer satisfaction rates
  • Potential rate increases with Signal

8. Travelers rating: 4.03 out of 5

Average monthly rate: $128

Travelers offers a number of car insurance coverage options in addition to property insurance products and other financial services. While the company boasts solid financial strength and fewer complaints than average, it’s seen its share of low customer satisfaction marks. And though Travelers’ quote process is easy, completing the purchase is less convenient because you have to call to finalize your policy.


  • Cheaper-than-average car insurance rates
  • Plentiful discount programs available
  • Wide array of available coverage options


  • Must purchase policies over the phone
  • More expensive than direct competitors
  • Below-average customer satisfaction scores

9. American Family Insurance rating: 3.63 out of 5

Average monthly rate: $94

American Family Insurance offers a wide range of car insurance coverages with customizable coverage limits. The insurer also boasts multiple discounts to help you save on your monthly premium.

You can also insure your home, business, and more with American Family Insurance. But the insurer only offers car insurance in 19 states, and has struggled with financial strength compared to its competitors.


  • Above-average customer satisfaction ratings
  • Multiple discount opportunities
  • Competitive rates for high-risk drivers


  • Only available in 19 states
  • Customer service varies by local agent
  • More expensive than many competitors

10. Nationwide rating: 3.8 out of 5

Average monthly rate: $123

Nationwide rounds out the list of largest insurers in the United States. The company — which has been in business for nearly 100 years — is ideal for drivers seeking specialty auto insurance coverage and full-coverage options.

Nationwide is also known for its wide-ranging coverages, discounts, and strong financial standing. But its rates are higher than many companies on this list, and the insurer struggles with customer service.


  • Plenty of savings opportunities
  • Highly rated local agents
  • Extensive coverage options


  • Higher-than-average rates
  • Below-average customer service scores
  • Reported issues with quote process

3 Tips for Choosing the Best Car Insurance Company

A person flipping through car insurance paperwork

We’ve gone over the 10 largest car insurance companies by market share, but that doesn’t mean your options end here. The right auto insurance company for you will depend on a number of factors, including price, customer service, available coverages, and more.

Here are a few things to consider when choosing your next auto insurance company:

Compare multiple companies

You might find a good fit on the first attempt, but be sure to check out a few other auto insurance companies. There could be a company that offers more discounts you’re eligible for or covers something you own that other companies don’t. And the only way to know you’re getting the best deal is by comparing personalized quotes from as many companies as possible. Fortunately, car insurance comparison sites do the hard work for you. Many work with more than 50 of the nation’s top companies, ensuring you find the best deal on your next policy.

Consider more than price

You obviously want to pay the least amount you can for proper car insurance, but the company with the lowest rate doesn’t always mean it’s the best fit. Be sure to consider what you’re sacrificing for low car insurance quotes. Are you still getting all the coverage you need? Does the insurer reward you for insuring more than one product with its company? What’s its claim process like? What do other customers think? All these questions are worth asking next time you’re considering switching companies.

Read customer reviews

Many companies offer cheap rates and great service, but seeing what others have to say about a car insurance company can help you sift through the advertising claims and find the best company for your needs. Pay close attention to what people have said about a company’s claims process and customer service. If the feedback is generally positive and the insurer offers competitive car insurance rates, you may have a winner.
