“Accounting profit” is not economic profit. All you need to see to understand that is inflation. If the value of money declines by 50%, many transactions which would show an “accounting profit” would in fact be economic losses. But absolutely every exchange whatsoever, absolutely every present tense action trade, only occurs because strict epistemological economic profit is made from receiving something of more value than that which is given away in exchange.
Your statement would perhaps be correct if you listed a giant assumption: ASSUMING THE SUBJECTIVE VALUE OF “MONEY” REMAINS CONSTANT, which of course it is by definition of trade NOT constant every time it is traded, even irrespective of any changes in the quantity of money.
Here’s Mises on “accounting”.
“Every businessman includes in his normal cost accounting the compensation for losses which regularly occur in the conduct of affairs. “Regularly” means in this context: The amount of these losses is known as far as the whole class of the various items is concerned. The fruit dealer may know, for instance, that one of every fifty apples will rot in this stock; but he does not know to which individual apple this will happen. He deals with such losses as with any other item in the bill of costs.” Part 1, Chapter VI. Uncertainty in paragraph 1.VI.21
“Nor are the assets and liabilities consisting in cash exempt from the indeterminacy inherent in all business accounting items. They depend on the future constellation of the market no less than any item of inventory or equipment. The numerical exactitude of business accounts and calculations must not prevent us from realizing the uncertainty and speculative character of their items and of all computations based on them.” Part 3, Chapter XII. The sphere of economic calculation in paragraph 3.XII.5
"Accounting and bookkeeping in their endeavors to establish the result of past action are in the same position as far as they rely upon the estimation of fixed equipment, inventories, and receivables. In spite of all these uncertainties economic calculation can achieve its tasks. For these uncertainties do not stem from deficiencies of the system of calculation. They are inherent in the essence of acting that always deals with the uncertain future." Part 3, Chapter XII. The sphere of economic calculation in paragraph 3.XII.39
“Monetary calculation reaches its full perfection in capital accounting. It establishes the money prices of the available means and confronts this total with the changes brought about by action and by the operation of other factors. This confrontation shows what changes occurred in the state of the acting men’s affairs and the magnitude of those changes; it makes success and failure, profit and loss ascertainable.” Part 3, Chapter XIII. Monetary calculation as a tool of action in paragraph 3.XIII.5
"Under capitalism the arithmetical operations required for cost accounting and the confrontation of costs and proceeds can easily be effected as there are methods of economic calculation available. However, cost accounting and calculation of the economic significance of business projects under consideration is not merely a mathematical problem which can be solved satisfactorily by all those familiar with Part 4, Chapter XVI. Prices in paragraph 4.XVI.58
“Cost accounting is therefore not an arithmetical process which can be established and examined by an indifferent umpire. It does not operate with uniquely determined magnitudes which can be found out in an objective way. Its essential items are the result of an understanding of future conditions, necessarily always colored by the entrepreneur’s opinion about the future state of the market.” Part 4, Chapter XVI. Prices in paragraph 4.XVI.69
“The capital concept is operative as far as men in their actions let themselves be guided by capital accounting. If the entrepreneur has employed factors of production in such a way that the money equivalent of the products at least equals the money equivalent of the factors expended, he is in a position to replace the capital goods expended by new capital goods the money equivalent of which equals the money equivalent of those expended. But the employment of the gross proceeds, their allotment to the maintenance of capital, consumption, and the accumulation of new capital is always the outcome of purposive action on the part of the entrepreneurs and capitalists. It is not “automatic”; it is by necessity the result of deliberate action. And it can be frustrated if the computation on which it is based was vitiated by negligence, error, or misjudgment of future conditions.” Part 4, Chapter XVIII. Action in the passing of time in paragraph 4.XVIII.116
"Those who have seen in this fact something puzzling and contradictory have been misled by a misconstruction of monetary calculation and capital accounting. They attempt to assign to capital accounting tasks which it can never achieve. Capital accounting is a mental tool of calculating and computing suitable for individuals and groups of individuals acting in the market economy. Only in the frame of monetary calculation can capital become computable. The sole task that capital accounting can perform is to show to the various individuals acting within a market economy whether the money equivalent of their funds devoted to acquisitive action has changed and to Part 4, Chapter XVIII. Action in the passing of time in paragraph 4.XVIII.134
"It would be a serious blunder to neglect the fact that inflation also generates forces which tend toward capital consumption. One of its consequences is that it falsifies economic calculation and accounting. It produces the phenomenon of illusory or apparent profits. If the annual depreciation quotas are determined in such a way as not to pay full regard to the fact that the replacement of worn-out equipment will require higher costs than the amount for which it was purchased in the past, they are obviously insufficient. If in selling inventories and products the whole difference between the price spent for their acquisition and the price realized in the sale is entered in the books as a surplus, the error is the same. If the rise in the prices of stocks and real estate is considered as a gain, the illusion is no less manifest. What makes people believe that inflation results in general prosperity is precisely such illusory gains. They feel lucky and become openhanded in spending and enjoying life. They embellish their homes, they build new mansions and patronize the entertainment business. In spending apparent gains, the fanciful result of false reckoning, they are consuming capital. It does not matter who these spenders are. They may be businessmen or stock jobbers. They may be wage earners whose demand for higher pay is satisfied by the easygoing employers who think that they are getting richer from Part 4, Chapter XX. Interest, credit expansion, and the trade cycle in paragraph 4.XX.36
