- calculating the change in a predetermined initial value of an investment over a time interval based on changes in value over a randomly-selected first historical time interval to obtain a changed investment value;
updating the changed investment value based on a selected contribution or withdrawal amount corresponding to the length of the time interval in accordance with the financial plan to obtain a further changed investment value; and
calculating the change in the further changed investment value over a second time interval based on changes over a second historical time interval, said second historical time interval being randomly-selected independent of said first historical time interval, to obtain a second changed investment value, and repeating said steps of calculating, updating and again calculating with respect to a third historical time interval and a fourth historical time interval, respectively, said third historical time interval and said fourth historical time interval being selected randomly.
