What is Marginal Income? »Its Definition and Meaning [2019]

It is the additional income that arises from the sale of an additional unit .For the relationship of the price of the product with the income and therefore the benefit it generates for a If the company sells this good, it is necessary to take into account the marginal income, since as long as the marginal income is positive, the total income of the sales will be growing.

in that sense, the marginal income represents the change that is generated in the total income , because of the sale of an additional unit.Thus, when a marginal income falls to zero or less, it means that a sale additional income is not increasing or decreasing total income.

On the other hand, when the demand curve is known, the marginal income curve can be derived Mathematics of it.Thus, at the point where the marginal income curve manages to intercept the horizontal axis, the appropriate level will be marked production that will maximize total income.

In cases where a company is part of a market, where there is free competition the marginal revenue is equal to the sale price.

On the other hand, if the company participates in a market that has perfect competition , that is, where all the companies that compete in the market with the same type of product, sell to same price, the marginal revenue curve is a horizontal line, equal to the unit price for all sales volumes.

Thus, as long as the marginal cost (additional cost resulting from producing and selling an additional unit) is less than the marginal income, which is given by the price, the production and additional sales will be profitable for the company.

However, when the marginal cost exceeds price, the company loses money in each of the additional units.That is why, the volume that m it approximates the profits is given by the amount for which the marginal cost is equal to the price.

The marginal income can remain constant , but the most common or normal is to follow the law of diminishing returns , where the greater the number of units produced, the lower the marginal income.

For a company it is profitable to produce more units , so that the marginal income is decreasing, as long as it is above or equal to the marginal cost.

The calculation of the marginal income is made by dividing the total income by the number of additional units sold.
