Life insurance provides a death benefit to beneficiaries that is paid out by an insurance company in exchange for premium payments from the insured. It is important for protecting dependents from financial loss if the primary income earner dies. There are two main types of life insurance - term insurance, which provides coverage for a set period of time without cash value accumulation, and permanent insurance, which provides lifetime coverage and allows cash value to grow within the policy. Factors like income needs of dependents and existing debts are considered to determine how much life insurance coverage is appropriate for an individual.
