TCO (Total Cost of Ownership) is the concept of calculating the total cost of owning a product (beyond the initial purchase price) over the course of its useful life. This includes accompanying items like maintenance and repairs, accessories and supplies, and the actual estimated life of the product.
In many cases, acquisition costs may account for an average of only 33% of the total cost for most products and services. The balance are associated costs of owning and using the product.
