Annual Operating Costs. You can determine the average annual operating costs by computing the average of the individual annual operating costs. In this example, they are estimated to be $8,000, $8,200, $8,400, and $8,600. The average for these figures is $8,300 which you obtain as follows: Annual operating costs = $8,000 + $8,200 + $8,400 + $8,600
