How to choose a life insurance company in 2025

What makes a good life insurance company? A few factors. When comparing life insurers, consider:

  • Financial strength ratings. These ratings are assigned by agencies like AM Best, and point to a company’s ability to pay out claims long into the future. Each ratings agency uses its own criteria and has its own ranking system, so an A+ from one agency will not mean the same as an A+ from another agency.

  • Complaint ratios. These indicate how satisfied customers are with the service they receive from their life insurance companies. NerdWallet’s star rating methodology assesses data from the National Association of Insurance Commissioners, and favors life insurers with low complaint volumes. The complaint volumes are adjusted for company size.

  • Policy options. Some companies specialize in term or permanent life insurance, but most offer both types. It’s important to choose a carrier that offers the type of policy that will meet your goals and needs.

Frequently asked questions

Life insurance companies issue policies that cover a person’s life — either for a set number of years or for a lifetime. These policies are contracts: The insured person pays premiums to maintain their coverage, and the life insurer pays out a sum of money to their beneficiaries when they die. Learn more about how life insurance works.

Northwestern Mutual is the biggest life insurance company in the United States, with 10.71% of the market share, according to the latest available data from S&P Global Market Intelligence. Founded in 1859, Northwestern Mutual is a longstanding mutual life insurance company owned by its policyholders.

A mutual life insurance company is owned by its policyholders, rather than outside stakeholders. It’s different from a stock insurance company, which is owned by shareholders and publicly traded. Some mutual life insurers operating in the U.S. include Northwestern Mutual, Guardian and Mutual of Omaha.

The best life insurance companies are financially strong and have a good track record in terms of customer satisfaction. They also offer various policies, like term and permanent life insurance, to cater to a wide range of people.

This decision comes down to personal preference. Many of the larger life insurance companies have been in business for decades or even hundreds of years, with strong financial ratings and resources across departments. Small life insurance companies tend to offer personalized service. It’s worth noting that some online-only insurers are often owned by larger companies that issue their policies.

No matter which route you choose, compare life insurance quotes to get the best possible price.
