## Definition of 'Marginal Cost of Production'

The marginal cost of production is the additional cost incurred by producing one more unit of a good or service. It is the change in total cost that results from producing one more unit of output.

The marginal cost of production can be calculated as the change in total cost divided by the change in output. For example, if the total cost of producing 10 units of output is \$100 and the total cost of producing 11 units of output is \$110, then the marginal cost of producing the 11th unit is \$10.

The marginal cost of production is an important concept in economics because it helps to determine the optimal level of production for a firm. A firm will produce up to the point where the marginal cost of production is equal to the marginal revenue from production. The marginal revenue from production is the additional revenue that a firm earns by selling one more unit of output.

The marginal cost of production can also be used to calculate the profit-maximizing level of output for a firm. A firm will maximize its profits by producing up to the point where the marginal cost of production is equal to the marginal revenue from production.

The marginal cost of production can vary depending on a number of factors, including the level of output, the type of production technology used, and the prices of inputs. As the level of output increases, the marginal cost of production typically decreases. This is because fixed costs are spread out over a larger number of units of output.

The type of production technology used can also affect the marginal cost of production. For example, a firm that uses a more efficient production technology will have a lower marginal cost of production than a firm that uses a less efficient production technology.

The prices of inputs can also affect the marginal cost of production. If the prices of inputs increase, the marginal cost of production will also increase. This is because the firm will have to pay more for the inputs that it uses to produce its output.

The marginal cost of production is an important concept in economics because it helps to determine the optimal level of production for a firm and the profit-maximizing level of output. The marginal cost of production can also be used to calculate the break-even point for a firm. The break-even point is the level of output at which a firm's total revenue is equal to its total cost.

The marginal cost of production is a dynamic concept. It can change over time as the level of output changes, the type of production technology used changes, and the prices of inputs change. Managers need to be aware of the marginal cost of production in order to make informed decisions about production.
