Total Cost of Ownership (TCO) — definition
Sum of acquisition, operating, maintenance and disposal costs of an asset over its useful life, used to compare purchase options beyond initial price.
Total cost of ownership incorporates energy consumption, spare parts, maintenance labour, downtime, financing cost and residual value alongside the purchase price. Equipment with a lower purchase price can have a higher total cost of ownership if it consumes more energy or requires more frequent maintenance.
Why it matters to industrial buyers
Evaluating purchases on TCO rather than price alone reduces the risk of selecting equipment that appears economical initially but costs more over its operating life.
Key reference points
Typical cost split
For industrial equipment, operating and maintenance costs over the asset life commonly exceed the initial purchase price.
Common inputs
Energy consumption, consumables, spare parts, downtime cost and financing cost are typical TCO components.
Commonly confused with
Should-cost analysis
TCO evaluates lifetime cost of an asset for the buyer; should-cost analysis estimates what a supplier's price should reasonably be based on cost build-up.
How it is used in practice
A buyer compares two compressor models by projecting energy use and maintenance costs over ten years, rather than relying on purchase price alone.
Frequently asked questions
How far into the future should a TCO analysis project?
It commonly spans the expected useful life of the asset, often 7–15 years for major industrial equipment.
Does TCO account for financing cost?
It can, particularly when comparing options with different financing structures or payment schedules.
