Families with small children usually need life insurance because parents want to make sure their children are taken care of and can go to college. Even when one parent is a full-time homemaker without an income, life insurance can help your spouse continue the care you provided, such as childcare and housekeeping. Empty nesters or people without children may still need insurance to pay off debt, cover funeral costs, help pay estate taxes or to borrow money against for retirement. And military members may want life insurance as a supplement to SGLI, or as a cheaper option to VGLI.
