The purpose of life insurance is to replace your income at the time of your death so that the family you are leaving behind can maintain their current lifestyle. How much you need is best decided by working with a qualified financial planner. Things to analyze include your current assets, savings and investments and how much earning power will be available for supporting your family in your absence. Compare that amount to your anticipated liabilities and expenses. Moreover, don't forget to include items such as college tuition for your children or paying off your mortgage, in addition to your standard living expenses.
