Life cycle costing, or whole-life costing, is the process of estimating how much money you will spend on an asset over the course of its useful life. Whole-life costing covers an asset’s costs from the time you purchase it to the time you get rid of it. Buying an asset is a cost commitment that extends beyond its price tag.
