Total Cost of Ownership is a financial estimate intended to help buyers and owners determine the direct and indirect costs of a product or service.
It includes all costs incurred throughout the life cycle of an asset or solution, from acquisition and implementation through maintenance, operation, support, and eventual disposal. TCO provides a comprehensive view of the financial impact of a purchase beyond just the initial price.
