Depreciation expense or simply depreciation, is the reduction in value of a fixed asset due to wear and tear. Most fixed assets have a limited life, the exception being land, and therefore depreciate over time. An estimate of the cost of depreciation is included in the income statement each accounting period and represents an expense of the business.
