Pros and cons of large car insurance companies
Large insurance companies tend to have more sophisticated technological platforms than their smaller competitors.
This, in turn, usually makes it more convenient to shop, manage your policy and file a claim with them. However, this doesn’t always translate into lower rates.
Depending on your driving record, ZIP code, age and other rate factors, a small or midsize company may give you a lower rate than a large company.
Also, size is not the only factor that determines an insurance company’s ability to provide quality customer service.
In J.D. Power’s customer survey on claims satisfaction, midsize companies occupy four of the top five positions. The highest rated company, Amica Mutual, ranks 22nd for size.
These are among the reasons to compare quotes from companies of all sizes when you shop for car insurance.

Do all agencies offer car insurance from major companies?
Most major auto insurance companies make it easy to shop online or by phone. However, they also sell their products through insurance agencies that are typically either independent or captive.
Independent agencies offer insurance products from multiple companies. Captive agents only sell insurance products from the company they work for.
Each type of car insurance agency has its pros and cons:
Car insurance agency type | Pros | Cons |
---|---|---|
Independent | Agents can compare prices from multiple companies for you. | Independent agents can not quote companies with captive agents. |
Captive | Agents have thorough knowledge of their company’s coverages and discounts. | You have to contact captive companies individually to compare quotes. |
Of the top 10 car insurance companies, these four work with independent agencies:
-
-
- Liberty Mutual
- Nationwide
- Progressive
- Travelers
-
These major auto insurance companies use captive agents:
-
-
- Allstate
- American Family
- Farmers
- State Farm
-
USAA and Geico also use captive agents, but they rely more heavily on online and phone services than most other major companies.
Methodology
Auto insurance company rankings are based on total U.S. premiums written, or amounts billed, in 2022, according to the National Association of Insurance Commission (NAIC).
Claims satisfaction ratings are based on the J.D. Power 2022 U.S. Auto Claims Satisfaction Study.
-
-
- Companies with a claims satisfaction score more than 1% higher than the industry average are very good.
- Those whose score is more than 1% lower than the industry average are poor.
-
Complaint ratings are based on the NAIC’s Complaint Index, which tracks confirmed complaints. Confirmed complaints are those that lead to a finding of fault. A 2.0 Complaint Index score reflects twice as many confirmed complaints as expected for a company’s size, and a 0.5 score reflects half as many.
-
-
- A Complaint Index score lower than 0.5 is very good.
- Scores between 0.5 and 0.9 are good.
- Scores between 0.9 and 1.1 are average.
- Scores above 1.1 are poor.
-
Average insurance company prices are based on an analysis of auto insurance quotes obtained from Quadrant Information Services for sample drivers across the U.S. Rates reflect prices quoted for policies for a male 30-year-old with these coverages, limits and deductibles:
-
-
- Bodily injury liability: $50,000 per person/$100,000 per accident
- Property damage liability: $25,000
- Collision: $500 deductible
- Comprehensive: $500 deductible
