Marginal cost and marginal revenue

Marginal revenue

The concept of marginal revenue is generically understood as the additional revenue the company generates from the sale of one more unit of its product or service. In a different formulation, the marginal revenue represents the money generated by the sale of the last item, be it product or service.

The marginal revenue is computed through the division of the change in total revenue by the change in quantity of sold items. This computation method also represents the relationship between the marginal revenue and the total revenue.

MR = Change in TR / Change in Q, where

MR is the marginal revenue

TR represents the total revenues, and Q. represents the quantity of items sold (Economics. Fundamental Finance).

Marginal cost

Similar to the marginal revenue, the marginal cost also refers to the change incurred relative to the unit of one product or service. Specifically, the marginal cost represents the change in total costs which is incurred as one more unit of product is being produced.

"The marginal cost of an additional unit of output is the cost of the additional inputs needed to produce that output. More formally, the marginal cost is the derivative of total production costs with respect to the level of output" (EconModel).

The interest in the marginal cost is represented by the fact that, as the production tends to increase, the cost of producing the specific items decreases. In other words, the marginal costs helps create advantages of the scale economy and allows manufacturers to find the optimal point at which profits are maximized.

3. Profit and profit maximization

The profit is computed by subtracting the total costs from the total revenues:

Profit = Total Revenue -- Total Expenses

The profit as such represents the amount of money that is left from the company's revenues after all costs have been covered. These costs include operational expenses, personnel costs, utilities, taxes as well as any other costs incurred in the efforts to make the business sustainable.

The profits do not belong to the organizational entity, but to the owner of the business. In turn, the owner / the owners are the ones to decide how the profits would be used. They could be reinvested in the firm, saved, invested in other personal and professional endeavors and so on (Investopedia).

The primary scope of each economic agent is that of maximizing its profit. Profit maximization traditionally refers to sustained efforts by which companies strive to generate more revenues, while decreasing costs. The Investor Words website explains:

Profit maximization refers to "a process that companies undergo to determine the best output and price levels in order to maximize its return. The company will usually adjust influential factors such as production costs, sale prices, and output levels as a way of reaching its profit goals."

4. Optimal output

The scope of profit maximizing organizations is that of identifying the optimal output for which there is demand for their products, where they can deliver the items and generate the highest possible level of revenues and profits. This specifically means that a balance has to be identified between the marginal cost and the marginal revenue. In the diagram below, this point of equilibrium -- the optimal output -- is represented at point A.

The explanation is quite simple: marginal profit equals marginal revenues minus marginal costs. If marginal revenues are higher than the marginal costs, then the marginal profit is positive; if, on the other hand, marginal revenue is lower than marginal cost, the marginal profit is negative. The total profit is directly influenced by the marginal profit in the meaning that a positive marginal profit generates increases in the total profits and a negative marginal profit generates decreases in the total profit. Given this relationship, companies strive to attain a point of equilibrium between marginal cost and marginal revenues in the meaning that they are equal -- marginal profit is as such zero. This point of balance represents the optimal output (Nowsell).
