| π is used to symbolize profit. (π = TR - TC) | ||
| Revenue per unit produced. (AR = TR/Q) NOTE: AR always equals Price. | ||
| The extra revenue earned from producing an extra unit of a good. The change in total revenue divided by the change in quantity. (MR = change TR/change Q) | ||

| The guide by which firms maximize profit (or minimize loss.) | ||
| When a firm faces the certainty of incurring losses, its goal is to incur the lowest loss possible with the production of its goods and services. | ||
| Ceasing operations - the firm's loss minimization occurs at zero output. |
