📊 Star rating categories
When NerdWallet evaluates life insurance companies, our editorial team considers the insurer's strengths and weaknesses, as well as the things that matter most to customers buying a long-term financial product. We then weigh these factors carefully:
💰 Financial strength (35%). We use AM Best ratings to confirm an insurer’s financial stability and ability to pay claims far into the future. The top life insurance companies have an exceptional financial strength rating of A+ or A++ (Superior).
🗣️ Consumer complaints (35%). Our top-rated life insurance companies have fewer than the expected number of complaints to state regulators over a three-year period, according to the National Association of Insurance Commissioners — so you can expect a smoother customer experience.
☎️ Consumer experience (20%). Insurers who allow consumers to contact them by email, phone and live chat earn the highest scores. The same goes for insurers who support online quotes, beneficiary changes and claims.
👀 Transparency (10%). Our methodology gives higher scores to transparent insurers who clearly display information about their policy options, coverage amounts and term lengths (if applicable) on their site.
⭐ What our star ratings mean
Companies with 5 stars are exceptional, with strong financials, diverse policy lineups and great reputations for customer service.
Companies with 4.5 stars are excellent, with solid financials and policy offerings, and good customer service track records.
Companies with 4.0 stars are good, and potentially great for people looking for niche coverage options.
Companies with 3.5 stars or fewer could do better in certain categories, like financial strength and customer complaints.
