Profit maximization using the total revenue and total cost curves of a perfect competitor. To obtain the profit maximizing output quantity, we start by recognizing that profit is equal to total revenue minus total cost (). Given a table of costs and revenues at each quantity, we can either compute equations or plot the data directly on a graph.
Only in the short run can a firm in a perfectly competitive market make an economic profit. Economic profit does not occur in perfect competition in long run equilibrium; if it did, there would be an incentive for new firms to enter the industry, aided by a lack of barriers to entry until there was no longer any economic profit.

In the long run a firm operates where marginal revenue equals long-run marginal costs, but only if it decides to remain in the industry. [30] Thus a perfectly competitive firm's long-run supply curve is the long-run marginal cost curve above the minimum point of the long-run average cost curve. [31]
The total cost curve, if non-linear, can represent increasing and diminishing marginal returns.. The short-run total cost (SRTC) and long-run total cost (LRTC) curves are increasing in the quantity of output produced because producing more output requires more labor usage in both the short and long runs, and because in the long run producing more output involves using more of the physical ...
The transition from the short-run to the long-run may be done by considering some short-run equilibrium that is also a long-run equilibrium as to supply and demand, then comparing that state against a new short-run and long-run equilibrium state from a change that disturbs equilibrium, say in the sales-tax rate, tracing out the short-run ...

A firm's short-run supply curve is the marginal cost curve above the shutdown point—the short-run marginal cost curve (SRMC) above the minimum average variable cost. The portion of the SRMC below the shutdown point is not part of the supply curve because the firm is not producing any output. [13]
Only in the short run can a firm in a perfectly competitive market make an economic profit. Companies do not make any economic profits in a perfectly competitive market once it has reached a long run equilibrium. If an economic profit was available, there would be an incentive for new firms to enter the industry, aided by a lack of barriers to ...
