A whole life insurance policy is a type of life insurance that provides lifetime protection.

Whole Life offers guarantees on a couple different levels as it applies to your life insurance policy.  

First, the death benefit is guaranteed to remain level,  and second, the premium is guaranteed to remain level, and lastly, the cash value is guaranteed. 

Whole life insurance policies build up cash value inside the whole life insurance policy over time. You may be able to take a loan from your cash value.

In addition, Whole life insurance may pay dividends (if you buy life insurance from a Mutual Life Insurance Company) to you or you can have them paid back into the life insurance policy to add more coverage or grow the cash value.
