Definition
Maintenance cost is the total expenditure attributable to keeping assets in service (labor, spare parts, contracted services, tools, and related overhead) tracked in absolute terms. It is the raw cost figure that other measures, such as maintenance cost as a percentage of RAV, put into context relative to the value of what is being maintained.
Key facts
- An absolute expenditure figure (labor, parts, contracted services, overhead) not yet related to asset value or output.
- Boundaries matter: whether spare-parts inventory carrying cost, overtime premiums, or contractor markup are included affects comparability.
- Read alone, a rising cost figure can mean more work is needed or that work is less efficient: it does not distinguish between the two.
- The raw figure that ratio-based measures like maintenance cost as a percentage of RAV are built from.
How is Maintenance cost calculated?
Maintenance cost covers every direct and indirect expenditure attributable to keeping assets functioning (technician labor and overtime, spare parts and materials, contracted or vendor services, tools and consumables, and allocated overhead) tracked as an absolute figure for a defined period and asset scope.
How it differs from maintenance cost as a percentage of RAV
Maintenance cost is the absolute expenditure figure by itself. Maintenance cost as a percentage of RAV relates that same expenditure to the replacement asset value it protects, turning an absolute number into a benchmarkable ratio: a plant with higher absolute maintenance cost is not necessarily spending inefficiently if its asset base is proportionally larger.

Frequently asked questions
Which expenditures belong to maintenance costs?
Maintenance cost covers labor, spare parts, contracted services, tools, and related overhead attributable to keeping assets in service: the absolute expenditure figure, before it is related to asset value as a percentage.
