When you need it
Use when alternatives have different purchase, operating, maintenance or replacement costs. Apply during option selection or asset renewal once a common service requirement and assessment horizon can be defined.

Lifecycle Cost Data and Review Worksheet
Blank worksheet for organizing lifecycle cost events, assumptions and results from a separately reviewed financial model. No discounting or lifecycle cost calculations are included.

How to use this template
What it helps you decide
The worksheet organizes costs that a purchase-price comparison misses. It helps reviewers identify whether a lower modeled lifetime cost depends on uncertain service life, operating assumptions or inconsistent financial treatment.
How to complete it
- Define Alternative / event and Service boundary so options provide comparable capacity and availability. Identify relevant renewal cycles and residual-life differences before comparing costs.
- Record Timing / frequency, Cost source and Amount / unit for capital, operation, maintenance and end-of-life events. Keep unresolved costs visible in the event schedule.
- State Financial basis and link Model result reference to a separately reviewed calculation. Test each Sensitivity driver; the worksheet supplies no discounting or lifecycle-cost formulas.
Who prepares and reviews it
An asset or cost analyst prepares it with engineering, operations and maintenance contributors. Finance reviews the separate calculation model and discount basis; the owner selects an option after technical suitability is considered independently.
A mistake to avoid
Combining future nominal costs with a real discount basis distorts the comparison, even when the spreadsheet appears internally precise and the purchase prices are correct.
Illustrative example
Illustrative example: a facility compares two ventilation units with different purchase prices, energy use and replacement needs. The worksheet records equivalent duty and evidence for each cost event. A reviewed model tests operating-hour assumptions before the owner decides which option deserves technical and procurement progression.
