Which term is the measure used to describe the cost of owning a product or service over its lifetime?

• A. Total Cost of Ownership (TCO)
• B. Net Present Value (NPV)
• C. Payback
• D. Single Loss Expectancy (SLE)

Answer: (A)

The main idea here is measuring all costs tied to owning something over its entire life. Total Cost of Ownership captures every expense from purchase and installation to maintenance, operation, upgrades, downtime, and eventual disposal. This holistic view lets you compare options by true lifetime cost, not just the upfront price.

Net Present Value focuses on whether an investment adds value over time by discounting future cash flows, which is about profitability rather than the complete ownership burden. Payback looks at how quickly you recover the initial investment but ignores ongoing costs and benefits after that point. Single Loss Expectancy is a risk metric for potential loss from a single incident, not a way to assess ongoing ownership costs.
