What lifecycle cost analysis is
Lifecycle cost analysis (LCA) calculates the total cost of owning an asset from acquisition through disposal. It includes the purchase price, installation, operating costs, maintenance, downtime, and end-of-life costs. The purpose is to support better acquisition and replacement decisions by showing the full cost picture rather than just the upfront price.
Components of lifecycle cost
A rigorous LCA captures costs at every stage of the asset's life.
- Acquisition: Purchase price, shipping, installation, commissioning
- Operation: Energy, consumables, operator labour, insurance
- Maintenance: Preventive, corrective, and predictive maintenance costs
- Downtime: Production loss, temporary replacements, overtime
- Upgrades: Technology refreshes, capacity expansions, compliance modifications
- Disposal: Decommissioning, environmental compliance, scrap or resale value
Using LCA for replacement decisions
The most valuable application of lifecycle cost analysis is determining the exact replacement point. As assets age, maintenance costs typically increase while performance and reliability decrease. LCA helps identify the crossover point where continuing to maintain an existing asset becomes more expensive than replacing it.
This analysis is particularly powerful when combined with condition data from the asset register and maintenance history from the work order system.
Common LCA mistakes
The most common mistakes are ignoring downtime costs, using generic maintenance estimates instead of actual data, failing to account for disposal and environmental costs, and not discounting future costs to present value for meaningful comparison.
