Editing Consumption of fixed capital (section)

==Capital Consumption Allowance==
The '''Capital Consumption Allowance''' ('''CCA''') is the portion of the [[gross domestic product]] (GDP) which is due to [[depreciation]]. The Capital Consumption Allowance measures the amount of expenditure that a country needs to undertake in order to maintain, as opposed to grow, its [[productivity]]. The CCA can be thought of as representing the wear-and-tear on the country's [[physical capital]], together with the investment needed to maintain the level of [[human capital]] (e.g. to educate the workers needed to replace retirees).

===Calculation===
[[Gross domestic product]] (GDP) equals [[net domestic product]] (NDP) + CCA (Capital Consumption Allowance):
