What Is Best Life Insurance Company? 
People define the best life insurance company in different ways . Some go by rating agencies : AM Best , S&P , Moody 's , Fitch , Weiss , or even independent sources like The Street . Some go by consumer ratings . Some judge life insurance companies by their size . For others , it is the one with the lowest price . So it is impossible to peg one life insurance company as the best as no one company fits these variables in every category . If you were to look just at agency ratings , New York Life , TIAA-CREF , and Northwestern Mutual all have highest ratings from the first four ratings agencies I listed above .
