Which item is NOT typically considered a cost category in life cycle cost analysis?

• A. Cost-to-life span ratio
• B. Initial investment
• C. Operating costs
• D. Maintenance costs

Answer: (A)

Understanding life cycle cost analysis means looking at all the costs that accrue over an asset’s life—from purchase to disposal. In LCCA, you group expenses into categories like initial investment (the upfront capital cost), operating costs (ongoing energy, utilities, and consumables during use), and maintenance costs (repairs and preventive upkeep). You may also consider replacement costs and the eventual salvage value, but you don’t treat a ratio itself as a cost category.

The item listed as a ratio—the cost-to-life span ratio—is a metric used to compare or normalize costs over the asset’s life. It helps you evaluate affordability or annualized cost, but it isn’t a type of cost you spend money on. That’s why it’s not typically considered a cost category in life cycle cost analysis.
