Revenue refers to the income derived by a producer or firm from business activities or from the sale of his or its products.
TYPES OF REVENUE
- TOTA REVENUE (TR): This refers to the total income which a firm derives from the sale of its products.
Total Revenue = Price x Quantity (TR = PxQ)
- AVERAGE REVENUE (A.R): The average revenue is the same as the price per unit of the commodity. It is derived by dividing the total revenue by the total unit of the commodity sold.
= = P
- Marginal revenue: This is the additional income earned by selling an extra unit of a commodity.

| 0 | 0 | 0 | – |
| 1 | 400 | 400 | 400 |
| 2 | 700 | 350 | 300 |
| 3 | 900 | 300 | 200 |
