Universal life insurance (UL) is a relatively new insurance product intended to provide permanent insurance coverage with greater flexibility in premium payment and the potential for greater growth of cash values. There are several types of universal life insurance policies which include "interest sensitive" (also known as "traditional fixed universal life insurance"), variable universal life (VUL), guaranteed death benefit, and equity indexed universal life insurance.
Universal life insurance addresses the perceived disadvantages of whole life – namely that premiums and death benefit are fixed. With universal life, both the premiums and death benefit are flexible. Except with regards to guaranteed death benefit universal life, this flexibility comes at a price: reduced guarantees.
Depending on how interest is credited, the internal rate of return can be higher because it moves with prevailing interest rates (interest-sensitive) or the financial markets (Equity Indexed Universal Life and Variable Universal Life). Mortality costs and administrative charges are known. And cash value may be considered more easily attainable because the owner can discontinue premiums if the cash value allows it.
Flexible death benefit means the policy owner can choose to decrease the death benefit. The death benefit could also be increased by the policy owner but that would (typically) require that the insured go through new underwriting. Another example of flexible death benefit is the ability to choose option A or option B death benefits - and to be able to change those options during the life of the insured.
