Economic Profit
Economic profit is a firm's total revenue minus its total costs, where these costs crucially include the opportunity cost of capital. This opportunity cost represents the minimum return required by shareholders to keep their funds invested in the firm, a concept also known as normal profits. Therefore, economic profit is any additional earnings above this minimum required return. A firm that earns zero economic profit is still covering all its costs, including the necessary payments to its owners.
