It is calculated by the change in total cost divided by the change in quantity produced: Marginal&nbsp;Cost&nbsp;(MC)=\u0394Total&nbsp;Cost\u0394Quantity\\text{Marginal Cost (MC)} = \\frac{\\Delta \\text{Total Cost}}{\\Delta \\text{Quantity}}<\/p>\n\n\n\n<p>Total cost (TC) is the sum of <strong>fixed costs (FC)<\/strong> and <strong>variable costs (VC)<\/strong>: TC=FC+VC\\text{TC} = \\text{FC} + \\text{VC}<\/p>\n\n\n\n<p>Fixed costs are those that <strong>do not change<\/strong> with the level of output (e.g., rent, salaries of permanent staff). In contrast, variable costs change with production levels (e.g., raw materials, wages of temporary workers).<\/p>\n\n\n\n<p>If <strong>fixed costs remain constant<\/strong>, they do not influence the marginal cost directly. However, <strong>if variable costs increase<\/strong>, it means that the <strong>cost to produce each additional unit is now higher<\/strong>. This directly impacts the marginal cost, causing it to <strong>increase<\/strong> as well.<\/p>\n\n\n\n<p>For example, suppose a company pays more for raw materials due to a shortage. Even though its rent (a fixed cost) hasn\u2019t changed, the cost of producing each additional unit has increased because each unit now uses more expensive inputs. This rise in per-unit variable cost causes a rise in marginal cost.<\/p>\n\n\n\n<p>In practical terms, increasing marginal cost is a common scenario in real-world production. This often happens due to diminishing marginal returns\u2014where adding more of a variable input (like labor) to a fixed input (like machinery) results in less efficient production.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Summary:<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Fixed costs do not affect marginal cost directly.<\/li>\n\n\n\n<li>An increase in variable cost increases total cost per additional unit.<\/li>\n\n\n\n<li>Therefore, <strong>marginal cost increases<\/strong> when <strong>variable costs increase<\/strong> while fixed costs remain constant.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>If a firm&#8217;s fixed cost remains constant, but its variable cost increases, what happens to the marginal cost?
