Marginal cost (MC)
Marginal cost follows a J-shaped pattern whereby cost initially declines but turns higher at some point in reflection of rising costs at higher production volumes.

it is not necessarily consistent with maximizing total profit. In Exhibit 13, the least-cost point of production is 3 units; ATC is 75, derived as [(225 ÷ 3) or (33.3 + 41.7)]. Any other production level results in a higher ATC. <span>Marginal cost (MC) is the change in total cost divided by the change in quantity. Marginal cost also can be calculated by taking the change in total variable cost and dividing by the change in quantity. It represents the cost of producing an additional unit. For example, at 9 units marginal cost is 300, calculated as [(1,300 – 1,000) ÷ (9 – 8)]. Marginal cost follows a J-shaped pattern whereby cost initially declines but turns higher at some point in reflection of rising costs at higher production volumes. In Exhibit 13, MC is the lowest at 2 units of output with a value of 25, derived as [(175 – 150) ÷ (2 – 1)]. <span><body><html>
