How to calculate the market added value,

Market added value = company market value-accumulated capital investment For enterprises, the higher the market added value, the better. High market added value shows that enterprises have created more wealth for shareholders. Theoretically, MVA is equal to the discounted value of future EVA, which means that MVA is the expected reflection of the market on the company's ability to obtain future EVA. If MVA is negative, it means that the value created by the company's investment activities is lower than the capital value invested by investors, indicating that investors' wealth or value is suffering. For an enterprise, its purpose is to maximize MVA, not enterprise value, because the latter can be achieved very simply by increasing investment. The biggest difference between EVA and profit-based enterprise performance evaluation index is that it also counts shareholders' equity capital (opportunity cost) into capital cost, and equity capital is no longer ignored as "free capital". It overcomes the defect that traditional accounting profits do not consider the cost of equity capital, and truly reflects the operating performance of enterprises. The traditional accounting profit only deducts the debt interest, without considering the capital cost of shareholders, which leads to many profitable enterprises that may actually damage the investment of shareholders. For example, when the EVA value is negative, although the enterprise may still have profits on its books, its value is lower than the equity cost (opportunity cost) of shareholders' investment. If shareholders invest in other enterprises, they can at least get the income equal to the average investment opportunity cost. For shareholders, the more EVA, the better, which is completely consistent with the ultimate goal of maximizing the value of corporate shareholders. Considering the total capital cost will force operators to pay attention to the capital cost related to inventory, accounts receivable and fixed assets investment, so as to use all assets of the enterprise cautiously. Economic Value Added (EVA) is a more accurate and reasonable method to evaluate the business performance of enterprises so far. It transforms accounting profits into profits in the economic sense, making economic benefits and accounting benefits more unified. EVA index contains powerful analysis function, which can better reflect the internal mechanism of enterprise operation. Taking EVA as an index to measure the business performance of an enterprise, we can measure the success of the operator, so as to determine the incentive reward for the operator, make the interests of the operator and the interests of shareholders highly unified, and make the operator really pursue the maximization of shareholders' wealth. The disadvantage of EVA is that it is based on the book value of the initial assets of the enterprise and does not consider the fluctuation of market value. In view of this, in 1997, scholars such as Jeffrey revised the economic added value. The revised economic value added (REVA) is based on the market value of enterprise assets, and its calculation formula is: REVA= adjusted operating net profit of the current enterprise-market value of enterprise assets at the beginning of the current period × weighted average cost of capital rate. This formula embodies the idea that the initial capital value of an enterprise is its market value. The difference between EVA and REVA is that
