If the hat factory was unable to handle any more units of production on the current machinery, the cost of adding an additional machine would how to calculate marginal cost need to be included in marginal cost. In this case, the cost of the new machine would need to be considered in the marginal cost of production calculation as well. The change in total expenses is the difference between the cost of manufacturing at one level and the cost of manufacturing at another.

Next, the change in total costs and change in quantity (i.e. production volume) must be tracked across a specified period. Marginal cost is often graphically depicted as a relationship between marginal revenue and average cost. The marginal cost slope will vary across company and product, but it is often a “U” shaped curve that initially decreases as efficiency is realized only to later potentially exponentially increase. If the selling price for a product is greater than the marginal cost, then earnings will still be greater than the added cost – a valid reason to continue production.
