Life insurance is a personal financial tool, so the right type of insurance for you depends on your goals and current situation. One of the main differences between term life insurance and whole life insurance is that term life insurance only covers you for a set period of time. Once you meet the premium payment requirements on a whole life plan, it covers you for the rest of your life. Whole life insurance also builds cash value, making it a potential investment. But whole life insurance is typically much more expensive than term life insurance.
