A Closer Look at the Biggest Car Insurance Companies
Let’s explore the key elements of each of the 10 biggest car insurance companies, including industry standing, availability, affordability, and coverage.
1. State Farm: Best for Student Drivers
State Farm is the biggest auto insurance company in the U.S. In our research, we’ve noted its financial strength and discounts for students. The company also has great customer service ratings. According to the NAIC, State Farm had 1,522 complaints in 2019, which is above average for an insurer, but State Farm commands more of the market than any other provider.
AM Best financial strength rating: A++ State availability: 48 states Affordability: Competitive prices and more than 10 discounts, including a 25-percent discount for students Coverage: Six standard coverage options as well as optional rideshare, rental car, and sports car and classic coverage
The second on our list of biggest car insurance companies, GEICO ranks well across the board. It’s available wherever you go, and it’s made the insurance process even easier with the GEICO mobile app. Along with the standard types of car insurance, you can get extras like mechanical breakdown insurance (MBI), which is similar to an extended car warranty.
AM Best financial strength rating: A++ State availability: 50 states Affordability: Very affordable coverage with more than 15 discounts and a coverage calculator Coverage: Standard coverage plus optional roadside assistance, rental reimbursement, and MBI
Also available in every state, Progressive has a mobile app and an online quote tool to aid you in pricing out your insurance plan and your claims process alike. We like Progressive’s variety of discounts, including those for teen and student drivers. However, customers have reported their claims process with the insurer to be just average.
AM Best financial strength rating: A+ State availability: 50 states Affordability: Competitive prices and two major savings programs (Snapshot and a deductible savings bank) Coverage: Standard coverage as well as optional rental car reimbursement, loan/lease payoff, and complementary pet coverage
The fourth biggest car insurance company, Allstate has a track record of being expensive, yet comprehensive. While we like its coverage options, especially for those who drive for Uber or Lyft, be prepared to pay for it. Allstate has higher prices than many of the biggest car insurance companies.
AM Best financial strength rating: A+ State availability: 50 states Affordability: Tends to be expensive with few discounts Coverage: Standard coverage as well as optional rideshare insurance, classic car insurance, and custom parts coverage
High premium prices
Support from local agents
Strong financial rating

5. USAA: Best for Military Families
USAA is one of our highest-ranking car insurers, but it’s only available to military members and their families. It’s known for its excellent claims servicing experience, accident forgiveness program, and low policy prices.
AM Best financial strength rating: A++ State availability: 50 states Affordability: Very affordable coverage and about 10 discounts, including a 15-percent discount for military servicemen Coverage: Standard coverage plus rideshare coverage, roadside assistance, and rental car reimbursement
We recommend Liberty Mutual for students and new drivers. Not only does it provide great discounts but also educational tools to build safe driving habits. However, Liberty Mutual is middle-of-the-road for prices, especially with reported frequent rate increases for policyholders.
AM Best financial strength rating: A State availability: 50 states Affordability: Average prices with quite a few discounts for new and student drivers Coverage: Standard coverage as well as accident forgiveness, rental car reimbursement, and other unique coverage options
We like Farmers’ non-standard coverage add-ons and bundling options, but customers have reported increasing rates and average service. However, Farmers might be a more affordable option if you’re dealing with a low credit score. The insurer also has a highly-rated mobile app that lets you manage your policy on the go.
AM Best financial strength rating: A State availability: 50 states Affordability: Tends to be expensive with discounts varying by state Coverage: Standard coverage plus towing and roadside service, rental reimbursement, and rideshare coverage

Based on our research into the biggest car insurance companies, Nationwide is a good choice for coverage. According to the 2019 J.D. Power U.S. Auto Claims Satisfaction Study, Nationwide is considered “average.” The highlight of Nationwide auto insurance, however, is its SmartRide program. A usage-based discount program, SmartRide gives you instructions for safer driving habits and could lead to discounts up to 40 percent.
AM Best financial strength rating: A+ State availability: 47 states Affordability: Average prices with many discounts, but excludes a new driver or military discount perk Coverage: Standard coverage alongside accident forgiveness, roadside assistance, and gap coverage
Inconsistent customer service

9. American Family
American Family is a great choice for bundling with an almost 30-percent discount for those with more than one policy. However, According to the J.D. Auto Claims Satisfaction Study, American Family is considered “average,” but on the lower end of average at that. It’s also only available in 19 states, all of which are mainly concentrated in the Midwest and California. If you’re on the East Coast, you should look for other options among the biggest car insurance companies.
AM Best financial strength rating: A+ State availability: 19 Affordability: Competitive rates with good discounts for bundling Coverage: Standard coverage and optional classic car insurance, commercial car insurance, and rideshare insurance

How to Choose the Best Insurer For You
Now that we’ve reviewed the biggest car insurance companies in the business, you should consider what you’re looking for in an auto insurer. There are pros and cons that come along with every coverage option, so let’s discuss your insurance priorities.
There are some big insurers on this list. State Farm, GEICO, and Progressive account for over 40 percent of the market alone. With bigger companies like these, you’re granted financial stability and lower premiums, but would you prefer to work with a smaller, local provider? Sometimes it can be hard to beat the customer service of a small company, but you will miss out on valuable perks and, in some cases, lower prices because the companies may not have the same financial bargaining chips as leading insurers.
