Payback period
The payback period identifies the point at which we estimate the
operating cost savings equal the acquisition costs and the
acquisition starts to show a cost benefit or profit. In calculating the
estimated payback period, we assume that investment costs occur
at the beginning of the year of the acquisition and annual or 3-year
operating costs spread evenly across the months.
Figure 15 shows the payback calculation for the Dell PowerEdge
R810 solution and the 24 HP ProLiant DL385 solutions.
