Liberty Mutual, founded in 1912, is one of the oldest insurance companies in the US. Liberty Mutual began as an employee's workers' compensation insurance program and wrote its first policies in 1914. Liberty Mutual is a national company, writing policies in all but a couple of states. However, due to their roots, they have a particularly strong brand in the northeastern portion of the United States. Liberty is headquartered in Boston, MA and has over 50,000 employees in 900 locations. Liberty Mutual is the Nation's sixth largest carrier, with a little over 5% market share.
The Car Insurance Guide uses a proprietary algorithm to evaluate the car insurance options presented. Factors reviewed and rated include pricing, handling of claims, age of driver, bundling, and driver type. These factors are evaluated and scored to provide an overall score for the carrier as well as being individually assessed to provide a detailed review of the fit of the carrier to the driver. The data comes from research The Car Insurance Guide conducts as an invite-only annual survey and from interviews with car insurance agents. Insights from experts, those whose job it is to understand and recommend the best insurance companies for their clients, is invaluable. Use of The Car Insurance Guide's 2021 reviews by third parties without the express written consent of The Car Insurance Guide is strictly prohibited.
