&lt;br /&gt;
The &#039;&#039;&#039;Capital Consumption Allowance&#039;&#039;&#039; (&#039;&#039;&#039;CCA&#039;&#039;&#039;) 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&#039;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).&lt;br /&gt;
&lt;br /&gt;
==Calculation==&lt;br /&gt;
[[Gross Domestic Product]] (GDP) equals Net Domestic Product (NDP) plus Capital Consumption Allowance plus Indirect Taxes (less subsidies; sales and excise taxes).  &lt;br /&gt;
&lt;br /&gt;
&amp;lt;math&amp;gt;GDP = NDP + CCA + Indirect Taxes &amp;lt;/math&amp;gt;&lt;br /&gt;
