Life insurance protection comes in many forms, and not all policies are created equal, as you will soon discover. While the death benefit amounts may be the same, the costs, structure, durations, etc. vary tremendously across the types of policies.
Whole Life
Whole life insurance provides guaranteed insurance protection for the entire life of the insured, otherwise known as permanent coverage. These policies carry a "cash value" component that grows tax deferred at a contractually guaranteed amount (usually a low interest rate) until the contract is surrendered. The premiums are usually level for the life of the insured and the death benefit is guaranteed for the insured's lifetime.
