We should remember, however, that this same line gives us the market price, average revenue, and the demand curve facing the firm. A perfectly competitive firm faces a horizontal demand curve at the market price. More generally, we can say that any perfectly competitive firm faces a horizontal demand curve at the market price.
We saw an example of a horizontal demand curve in the module on elasticity. Such a curve is perfectly elastic, meaning that any quantity is demanded at a given price. Note that Figure 9. This video demonstrates how average revenue equals marginal revenue, which equals price in a perfectly competitive market.

Reading: Price and Revenue in a Perfectly Competitive Industry and Firm Price and Revenue Each firm in a perfectly competitive market is a price taker; the equilibrium price and industry output are determined by demand and supply.
Two other terms closely related to average revenue are total revenue and marginal revenue. It's good to know the difference between these terms for clarity. Here are their definitions:. Related: Total Revenue vs. Marginal Revenue: What's the Difference? Many companies use the average revenue formula to analyze and forecast their revenue.
Telecommunication companies, like cell phone carriers, may use ARPU on a monthly basis. They use the average revenue formula to calculate and track the amount of revenue generated for each cell phone user.
Cable companies also calculate ARPU for their subscription users and use that data internally, externally, as a comparison to other companies and for forecasting future revenue. Social media platforms use average revenue to explain gaps in valuation, track sources of revenue and report to investors.
The relationship between the amount of goods produced and average revenue gets determined by one of the four market structures, perfect competition, monopoly, monopolistic competition and oligopoly. In a company with perfect competition, the average revenue is equal to the price and equal to marginal revenue. In the other three market structures, the average revenue is greater than the price and marginal revenue.
The larger the quantity of output, the more the price and marginal revenue will decrease, showing the market control of the company. Related: What Is Perfect Competition?
You calculate the average revenue of a unit or user by taking the total amount of revenue and dividing it by the number of units or users during a specific time period. The number of units or users can vary throughout the specified time period, so the number of units or users gets estimated, or a weighted average gets used, in order to provide the most accurate calculation possible.

What Is Marginal Revenue? Key Takeaways Marginal revenue refers to the incremental change in earnings resulting from the sale of one additional unit. Analyzing marginal revenue helps a company identify the revenue generated from one additional unit of production. A company that is looking to maximize its profits will produce up to the point where marginal cost equals marginal revenue. When marginal revenue falls below marginal cost, firms typically do a cost-benefit analysis and halt production.
