Definition
Economic Life refers to the remaining period for which a machine or other property is expected to generate more revenue than operating expenses. This period is crucial for businesses as it indicates the duration during which an asset is profitable and viable for continued use before it becomes more cost-effective to replace or retire the asset.
Examples
-
Manufacturing Equipment: A piece of equipment in a manufacturing plant might have an economic life of 10 years, where the revenues generated from its production capabilities exceed the operating and maintenance costs for those 10 years.
-
Commercial Property: A commercial real estate property might have an economic life of 30 years if the rental income consistently exceeds upkeep, taxes, and other operating expenses for that duration.
-
Vehicle Fleet: A delivery company’s van might have an economic life of 5 years, after which the maintenance and operational costs might outweigh the financial benefits from its use.
