CCE Life Cycle Costing & Total Cost of Ownership 2 — Questions and Answers
Question 1: Total Cost of Ownership (TCO) differs from a simple purchase price analysis primarily because TCO:
- Only considers direct manufacturing costs
- Includes all direct and indirect costs associated with acquiring, operating, and retiring an asset (Correct answer)
- Focuses solely on warranty and service contract expenses
- Excludes disposal and end-of-life costs from the calculation
Correct answer: Includes all direct and indirect costs associated with acquiring, operating, and retiring an asset
TCO captures both visible costs (purchase price, maintenance) and hidden costs (training, downtime, disposal) to reveal the true economic burden of ownership.
Question 2: In LCCA, a 'study period' is BEST described as:
- The manufacturer's stated warranty period
- The time required to recover the initial investment through savings
- The time span over which alternatives are compared, encompassing the planning horizon (Correct answer)
- The period between major overhauls or capital replacements
Correct answer: The time span over which alternatives are compared, encompassing the planning horizon
The study period is selected by the analyst to match the decision-making horizon and must be identical for all alternatives being compared.
Question 3: When the real discount rate is used in LCCA (as opposed to the nominal rate), future cost estimates should be expressed in:
- Current (constant) dollars, excluding general inflation (Correct answer)
- Future (nominal) dollars, including projected inflation
- Base-year dollars escalated at the CPI rate
- International dollars adjusted for purchasing power parity
Correct answer: Current (constant) dollars, excluding general inflation
The real discount rate already strips out general inflation, so cost estimates in constant (today's) dollars are appropriate — using nominal dollars with a real rate would double-count inflation.
Question 4: Sensitivity analysis in Life Cycle Cost studies is performed to:
- Identify which input variables most significantly affect the LCC outcome (Correct answer)
- Eliminate all uncertainty from the cost model
- Replace probabilistic estimates with deterministic values
- Confirm that the discount rate selected is federally mandated
Correct answer: Identify which input variables most significantly affect the LCC outcome
Sensitivity analysis varies key assumptions (discount rate, useful life, energy prices) to determine which variables drive LCC decisions most, revealing where estimates must be most accurate.
Question 5: Which of the following is an example of an indirect cost that should be included in a Total Cost of Ownership analysis for manufacturing equipment?
- Invoice price paid to the equipment vendor
- Freight and installation charges
- Lost production revenue during unplanned downtime (Correct answer)
- Annual property tax on the equipment
Correct answer: Lost production revenue during unplanned downtime
Lost production during downtime is a hidden indirect cost of ownership that TCO analysis captures but a simple purchase-price comparison would miss.
Question 6: The breakeven point in an LCCA comparing two alternatives is reached when:
- Both alternatives have recovered their initial investment
- The cumulative LCC of both alternatives is equal at a specific point in time (Correct answer)
- The more expensive alternative achieves a positive net present value
- Annual maintenance costs of both alternatives become identical
Correct answer: The cumulative LCC of both alternatives is equal at a specific point in time
The breakeven point marks the time or usage level at which the alternative with a higher initial cost has accumulated enough savings to equal the cumulative LCC of the lower-cost alternative.
Question 7: According to LCCA best practices, replacement costs for a major component within the study period should be:
- Ignored if the component lasts more than 10 years
- Treated as a single future cost and discounted to present value (Correct answer)
- Added to the initial capital cost without adjustment
- Expensed entirely in the year the analysis is performed
Correct answer: Treated as a single future cost and discounted to present value
Replacement costs occurring at a known future date are discounted back to present value using the Single Present Worth factor so they can be added to other LCC elements consistently.
Total Cost of Ownership (TCO) differs from a simple purchase price analysis primarily because TCO:
