"Marginal cost" represents the additional amount required in producing one further unit of goods or help. For instance, if it costs $150 to manufacture five carpets, and the expense of manufacturing six carpets is $165, then the marginal charge is $15. Producers will factor in marginal prices when determining how much to price for a good or assistance.
