Because the marginal cost curve measures the cost of each additional unit, we can think of the area under the marginal cost curve over some range of output as measuring the total cost of that output. When equilibrium is not achieved, parties who would have willingly entered the market are excluded due to the non-market price. As a result, the market fails to supply the socially optimal amount of the good. Further, if customers are unable to afford the product or servicedemand falls.

In this particular graph, the firm is earning a total revenue of $500, which is calculated by multiplying the price they are receiving for each unit by the profit-maximizing output. was just slightly higher, or the marginal revenue The allocatively efficient quantity of output, or the socially optimal quantity, is where the demand equals marginal cost, but the monopoly will not produce at this point. A monopolist calculates its profit or loss by using its average cost (AC) curve to determine its production costs and then subtracting that number from total revenue (TR). Subtracting this cost from the benefit gives us the net gain of moving from the monopoly to the competitive solution; it is the shaded area GRC.
