Total cost of ownership (TCO) is a financial estimate designed to help consumers and enterprise managers assess direct and indirect costs related to the purchase of any capital investment. In industry, automation computer software or hardware has a high capital investment, with little or no recoverable costs due to the fact that most control systems, with the exception of packaged equipment, are one off designs. A TCO assessment ideally offers a final statement reflecting not only the cost of purchase but all aspects in the further use and maintenance of the equipment, device, or system considered.
