Methodology, broken down by category

Our star ratings summarize how each life insurer performs in four key areas that matter for long‑term policyholders:

5.0

Overall score

Life insurance is a decades‑long promise. One way to gauge a life insurer’s ability to make good on that promise is by looking into its financial strength and credit ratings. Financial strength ratings from AM Best, the leading credit rating agency for the insurance industry, are an important measurement of a life insurance company’s financial stability — or, more specifically, its ability to pay out death benefits to beneficiaries 20 or 30 years down the road.

NAIC complaints rating (35%)

NerdWallet evaluates consumer complaints using the National Association of Insurance Commissioners (NAIC) Complaint Index for individual life insurance. The NAIC collects complaints submitted by customers to state insurance departments. It then compiles and aggregates this information by company and line of business. You can calculate a company’s complaint index rating yourself by dividing its share of complaints by its share of premiums for a particular line of business.

Consumer experience rating (20%)

Over the past two decades, the financial services industry has transformed how consumers interact with its products. As a result, consumers have come to expect a seamless digital experience across all of their financial products — be it their individual retirement account or their life insurance policy.

Transparency (10%)

Clear, public information related to available policy types, term lengths, coverage limits, eligibility and riders — as well as how much it all costs — can help shoppers better understand what they’re applying for before sharing personal data in the application process. We award more credit when key details are easy to find and specific.

Data collection and the review process

We collect data points for each insurer from its public-facing websites and from company representatives, public filings, state regulator data and third-party analyses. These data points are then compared against one another and against NerdWallet's standards for good insurance companies to determine a star rating.

Data is collected on a regular basis and reviewed by our editorial team for consistency and accuracy. Final star ratings are presented on a scale of one to five stars, where a one-star score represents "poor" and a five-star score represents "excellent."

More about our scores by category

Financial strength rating 🏦 (35%)

For our life insurance ratings, we looked at the AM Best financial strength rating of the insurer’s primary underwriting company, which is the entity responsible for approving and paying out claims. If a company has a higher AM Best rating, this means it's better positioned to meet its financial obligations even after an economic downturn or natural disaster.

Conversely, companies with a lower AM Best rating may not offer the same level of confidence to policyholders, and therefore are assigned a lower financial strength rating. If a company doesn’t have a financial strength rating with AM Best, then it isn’t eligible for NerdWallet’s overall star rating. For life insurance, our financial strength rating accounts for 35% of our overall rating.

AM Best Rating	Points
A++	5.00
A+	4.50
A	4.25
A-	4.00
B++	3.50
B+	3.00
B	2.50
B-	2.00
C++	1.50
C+	1.00
C	0.50
C-	0.00

NAIC complaints rating 📣 (35%)

The NAIC complaints rating index is normalized so the expected complaint index value is always equal to 1.00. Scores below 1.00 indicate fewer-than-expected complaints, while scores above 1.00 indicate more-than-expected complaints from customers. Persistent, above‑expected complaint levels can potentially point to a pattern of customer service issues at key consumer touchpoints, such as claims handling, making this an important consumer experience metric.

To reduce year-to-year volatility, we calculate the three-year average of each life insurer’s NAIC Complaint Index and convert it to a score for NerdWallet’s ratings. We obtain the raw NAIC data annually, aggregate results at the company level, and fact-check these results vigorously before calculating our own NerdWallet complaint ratings. For life insurance, our complaints rating accounts for 35% of the overall star rating.

NAIC Complaints Ratio	Points
0.00 to 0.27	5.0
0.28 to 0.45	4.5
0.46 to 0.80	4.0
0.81 to 1.15	3.5
1.16 to 1.50	3.0
1.51 to 1.85	2.5
1.86 to 2.20	2.0
2.21 to 2.55	1.5
2.56 to 2.90	1.0
2.91 or higher	0.5

Consumer experience rating 🤝 (20%)

Digital self-service options for getting quotes, filing a claim, policy changes, or customer service interactions are no longer just nice-to-haves, but the expectation of policyholders. By replacing paper forms and processes with their digital equivalent, insurers can reduce unnecessary consumer friction, speed up service, and make it easier for families to act when timing matters.
