Why should I pick a large car insurance company?
Purchasing a policy from a large auto insurer could have multiple benefits since major carriers tend to have vast resources to offer. One factor to consider when choosing the right car insurance company for you is a company’s stability.
With more premiums written, a large insurance company is often more financially stable than a smaller, regional carrier that is more limited in its scope. While some national carriers may have higher rates than regional insurers, they may also be able to offer more discounts and savings programs that policyholders can use to lower their costs.
Large auto insurance companies also tend to offer extended customer service hours, sometimes even offering 24/7 instant support by phone and chat. Smaller car insurance companies may not have the resources to maintain these extended levels of customer support.
When it comes to whether a large insurance company or small company is better, it depends on your needs and what you want in an auto insurer.
Benefits of choosing a large insurance company
Generally more financially stable
Might offer more discounts
Extended customer service hours
Faster claims processing
Customer service can be delayed due to volume
Policyholders may receive less individualized assistance
Available agents online or via phone may be less likely to understand the unique needs of drivers in your region
Frequently asked questions
Bankrate utilizes Quadrant Information Services to analyze 2023 rates for ZIP codes and carriers in all 50 states and Washington, D.C. Rates are weighted based on the population density in each geographic region. Quoted rates are based on a 40-year-old male and female driver with a clean driving record, good credit and the following full coverage limits:
- $100,000 bodily injury liability per person
- $300,000 bodily injury liability per accident
- $50,000 property damage liability per accident
- $100,000 uninsured motorist bodily injury per person
- $300,000 uninsured motorist bodily injury per accident
- $500 collision deductible
- $500 comprehensive deductible
To determine minimum coverage limits, Bankrate used minimum coverage that meets each state’s requirements. Our base profile drivers own a 2021 Toyota Camry, commute five days a week and drive 12,000 miles annually.
These are sample rates and should only be used for comparative purposes.
Our 2023 Bankrate Score considers variables our insurance editorial team determined impacts policyholders’ experiences with an insurance company. These rating factors include a robust assessment of each company’s product availability, financial strength ratings, online capabilities and customer and claims support accessibility. Each factor was added to a category, and these categories were weighted in a tiered approach to analyze how companies perform in key customer-impacting categories.
Like our previous Bankrate Scores, each category was assigned a metric to determine performance, and the weighted sum adds up to a company’s total Bankrate Score — out of 5 points. This year, our 2023 scoring model provides a more comprehensive view, indicating when companies excel across several key areas and better highlighting where they fall short.
- Tier 1 (Cost & ratings): To determine how well auto and home insurance companies satisfy these priorities, 2023 quoted premiums from Quadrant Information Services (if available), as well as any of the latest third-party agency ratings from J.D. Power, AM Best and the NAIC, were analyzed.
- Tier 2 (Coverage & savings): We assessed companies’ coverage options and availability to help policyholders find a provider that balances cost with coverage. Additionally, we evaluated each company’s discount options listed on its website.
- Tier 3 (Support): To encompass the many ways an auto insurance company can support policyholders, we analyzed avenues of customer accessibility along with community support. This analysis incorporated additional financial strength ratings from S&P and Moody’s and factored a company’s corporate sustainability efforts.
