Insured Value There are different methods to calculate the amount of insured value you should obtain. One of them is to determine the amount of financial support you would expect to give your family throughout your working life. This will help you choose a specific amount to enable your family to maintain the same quality of life. Another way to calculate this insured value is to determine a specific need you would like to cover, such as a mortgage or an education fund. The size of your policy is typically correlated with the value of your estate. The greater the estate, the greater the amount of insurance you should have.
