Total Cost of Ownership (TCO)
Total Cost of Ownership (TCO) is the comprehensive accounting of all costs associated with a system over its full lifetime, including purchase price, implementation, training, maintenance, upgrades, infrastructure, internal labor, and migration. In PLM deployment decisions, TCO analysis frequently reverses the apparent cost advantage of on-premise perpetual licensing when internal labor and upgrade project costs are counted honestly.
Why it matters
PLM deployment decisions made on license cost alone consistently underestimate the true cost of on-premise. TCO analysis that includes internal DBA labor, server refresh cycles, and upgrade project costs typically changes the comparison significantly—sometimes reversing the conclusion.
