In the case of death, life insurance will provide a form of income for your dependents, children or whoever is your beneficiary. Because of this, married couples usually require more life insurance than singles. Having someone dependent on your income will determine if you need to have life insurance. If someone such as a child, parent, spouse or other individual is dependent on your income, you should have life insurance. The following are situations where life insurance is necessary: Single parents or families with young children or other dependents. The younger your children, the more insurance is necessary. Insurance should be in proportion to the amount earned. If both spouses are working, they should both be insured. If both earners cannot afford to be insured, the primary wage earner should be the first to be insured and the secondary will follow. To fill the insurance gap, a less expensive term policy may be used. Insurance should be bought to cover the absence of services such as childcare, bookkeeping, housekeeping, which are provided by the spouse that works within the home. The insurance that covers the non-wage earner is secondary to the insurance that covers the wage earner's life, if funds are scarce. Adults that have no children or other dependents. You will need less insurance than people in the previous situation if your spouse can live comfortably without income. However, some form of life insurance is still necessary. You will want at least enough to cover burial expenses, to pay off any debts you may have acquired, and to provide an easy transition for the surviving spouse. You may want to buy more insurance if you think your spouse would go through financial hardship without your income or if your savings aren't adequate. This depends on your salary level as well as the amount of your spouse's, the amount of savings you have and the amount of debt incurred. Single adults without dependents. Unless you would like to use insurance for the purposes of estate planning, you will only need insurance to cover expenses for burial and debts. Children. Typically, children only need life insurance to cover burial expenses and medical debts. An insurance policy could also be used as a long-term savings instrument, in some instances.
