Average Cost (AC)

The average cost is the total cost divided by the number of units produced.

It is important to understand that firms maximize profits by considering the marginal cost, not the average cost.  The difference between the average cost and the sales price does determine the profits per unit once the profit maximizing quantity is determined, but the profit maximizing quantity generally does not maximize profits per unit.

Perfect Competition and Monopoly emphasize the roles of average cost and marginal cost curves.
