In economics, profit in the accounting sense of the excess of revenue over cost is the sum of two components: normal profit and economic profit.
 Normal profit is the profit that is necessary to just cover the opportunity costs of the owner-manager or of the firm's investors.
 In the absence of this much profit, these parties would withdraw their time and funds from the firm and use them to better advantage elsewhere.
 In contrast, economic profit, sometimes called excess profit, is profit in excess of what is required to cover the opportunity costs.
