Let us consider a scenario where a Purchase order for a desktop has been placed. The total cost of the desktop for its whole life can be split into Purchase Cost, Operational Cost (which includes component cost), and its Disposal Cost. The operational cost can include the amount spent on servicing the desktop every year. On configuring the depreciation for the asset, the current value of the asset after its depreciation value will be displayed as Current Book Value. Any additional components like keyboard, mouse, speakers, etc., purchased along with the desktop will be added as component cost. Thus, the Total Cost of Ownership indicates the total sum of all the costs spent on purchasing, maintaining, disposing of the asset, and the component cost.
