While this question may seem like it has an obvious answer, many people wait too long to purchase life insurance and then can only afford enough to pay final expenses. At that point, they think of it—more appropriately, perhaps—as burial insurance. The real purpose of life insurance, however, is to ensure that the people you love will be able to go on living—without undue hardship—in the event of your untimely death. It takes a spouse about three years to recover financially, rearranging bills and adjusting to one paycheck, after a partner dies. If children are involved, the adjustment takes an average of five years if both partners had received an income. If one parent had a lower income or had been staying at home to raise the children, that individual will have to go out and find work. The work is often service work of an unskilled nature. Thus, his/her income will need to be supplemented at least until the children are grown.

People who have significant wealth to the point that life insurance is not a necessity often purchase life insurance as a legacy, intending for the proceeds to benefit a charity or provide an education for grandchildren. It can also provide a means of keeping a business going if the key person dies, or a way for heirs to pay taxes on a large estate.

Owning enough life insurance to completely provide for your family may sound like an impossibility. However, with the right kind of policy and thoughtful financial planning, it isn't as difficult as you may think.

Life insurance comes in three basic types, whole life, universal life—also known as UL—and Term. Each of those types has multiple modifications, depending on the company. Thus, while we can educate you here, it is still important to work directly with a licensed representative of a company of your choice. The company is not legally responsible if you purchase a contract that contains clauses you did not understand. It is your responsibility to understand the type of insurance you purchase as well as any particular variations created by the company.
