Whole life insurance is a type of permanent life insurance that provides coverage for the insured's entire life, as long as premiums are paid. It combines a death benefit with a cash value component that grows over time at a guaranteed rate. Unlike term life insurance, which only provides coverage for a specific period (e.g., 10, 20, or 30 years), whole life insurance remains in force for the policyholder's lifetime and includes an investment aspect through its cash value.
