Marginal cost is the additional cost attributed to an additional unit produced. Marginal product is the increase in the total product due to an additional resource allocation. The marginal cost and marginal return have an inverse relationship and can almost be represented as mirror images of each other.

The peak of the marginal product corresponds with the lowest point of the marginal cost. Thus as marginal product increases, the marginal cost decreases and vice versa. The relationship can be attributed to the law of diminishing returns. As we start adding labor, the output per additional labor increases and this means that the marginal product increases, and thereby the marginal costs decrease; however, if we continue adding more labor, they may get in each other’s way, may become inefficient and thereby reduce the marginal product and this in turn will increase the marginal cost.
The formula explains the relationship between marginal cost and marginal product MC= P /MPL
(Where MC is the marginal cost, P is the wage rate of labor and MPL is the marginal product).
Consider that marginal product is 5 additional units per unit labor and the wage rate of labor as \$15. Hence the marginal cost is 15/5 = \$3.
Now say we employ more labor and the marginal product is 10 additional units per labor, then the marginal cost is 15/10= \$1.5.
We observe that as the marginal product increases from 5 to 10 units, the marginal cost decreases from \$3 to \$1.5. This proves the inverse relationship between marginal cost and marginal cost.

B: Marginal cost is the variation in the total cost of production as a result of the production of one more or one less unit. Marginal cost is important in figuring out whether or not to vary the production rate. Typically, marginal cost decreases as the output increases due to factors such as the cost of bulk rate materials, the efficient use of the existing equipment and labor specializations of the employees. A sale at a price higher than the average marginal cost will result in the company making more profit even though the price doesn’t cover the average total unit cost. Marginal cost can be seen as the lowest amount at which a sale can be made without subtracting from the profits of a company. Marginal Cost = Total Cost divided by Quantity or (Marginal Cost)…

Marginal cost is the added cost for a company to make one or more units of production. Total cost (TC) is the combination of all variable and fixed cost expenses at various levels of production. The total fixed costs are steady costs that are not dependent on the level of output and remain the same no matter how much product is produced verses that variable total costs increase or decrease depending on the number of items produced in a particular time period. To calculate marginal cost, you would need to divide the total cost by the total output. “Marginal costs are costs the firm can control directly and immediately. Specifically, MC designates all the cost incurred in producing the last unit of output. Thus, it also designates the cost that can be “saved” by not producing that…

Marginal Costs- Marginal cost is the change in total cost when one more unit is produced. Marginal cost occurs when an activity increases by one unit. When the firm increases its production the total cost always increases even though the marginal costs may not rise. Rise in marginal costs is shown in the below chart.

CH 3. 2. Appalachian Coal Mining believes that it can increase labor productivity and, therefore, net revenue by reducing air pollution in its mines. It estimates that the marginal cost function for reducing pollution by installing additional capital equipment is MC = 40P where P represents a reduction of one unit of pollution in the mines. It also feels that for every unit of pollution reduction the marginal increase in revenue (MR) is MR = 1,000 - 10P…

On the other hand, marginal cost is the change in the total cost that comes from the production of one more unit of good. To calculate marginal cost, a company would divide the change in total cost by the quantity produced in that period.

Marginal cost is the fluctuating cost of producing a particular product, so it may cost \$1.00 to produce a single product, but as you produce more quantity the cost to produce goes down, say it only cost \$.25 per unit when producing 1000 units. With most products there is what I like to call a sweet spot in the marginal cost that is at some given quantity the marginal cost will no longer go down with more units produced, but begin to rise slightly. This may be due to the availability of your materials, the distance you have to ship them and so on. Marginal cost will fluctuate, as previously stated, but fixed cost should stay the same for a given amount of time say one year. Fixed cost would be your businesses overhead like pay roll, utility cost, building cost and so on. As your marginal cost fluctuates it also caused your total cost to fluctuate, to figure your total cost you add marginal cost and fixed cost, so if your marginal cost increase so does your total cost.…

Suppose Mr. X is hungry and eats oranges one by one. The first orange gives him great pleasure. By the time he starts taking the second, the intensity of his desire diminishes to a certain extent, and second orange yields less satisfaction. The satisfaction derived from the third will be less than that of the second, that of the fourth less than that of the third and so on. In this way, the incremental utility will go on decreasing till it drops to zero, and if he takes more, the satisfaction may become even negative or disutility may creep in. Zero utility means the consumer is not in need of the commodity any further. For each additionally unit an individual consumes, the marginal utility is less than the previous unit. Alfred Marshall in his book ‘Principles of Economics’ gave a precise explanation of this: “The additional benefit which a person derives from a given increase of his stock of a thing diminishes with every increase in the stock that he already has.”…

The basic average cost and marginal cost of a company are very different concepts, but they work together and fluctuate up and down according to how the other cost grows or declines. Average cost can be described as the ratio of the total cost to the total number of goods sold. It is equal to the total cost of the goods sold divided by the number of items sold. It has a very strong relationship with the supply and demand curves. Average cost can also be described as the sum of the average variable costs and average fixed costs. On the other hand, marginal cost is the cost that has incurred due to an additional unit or product. The average cost and marginal cost are inter-related because when the marginal cost goes up, or down, the average cost will fluctuate as well.…
