What is marginal revenue?

Copy link to section

Marginal revenue (MR) refers to the increase in total revenue that a company earns by selling one additional unit of a product or service. It is a key concept in microeconomics and business, providing insight into how changes in sales volume affect a firm’s overall revenue. By analyzing MR, companies can make informed decisions about pricing, production, and sales strategies.

In perfectly competitive markets, marginal revenue is equal to the price of the product, as firms can sell additional units at a constant price. However, in imperfectly competitive markets, such as monopolies or oligopolies, marginal revenue decreases as more units are sold due to the downward-sloping demand curve.

How to calculate marginal revenue

The marginal revenue is calculated using the following formula:
[
\text{MR} = \frac{\Delta \text{TR}}{\Delta \text{Q}}
]
where:

  • (\Delta \text{TR}) is the change in total revenue
  • (\Delta \text{Q}) is the change in quantity sold

For example, if a company’s total revenue increases from $1,000 to $1,200 by selling an additional 10 units, the marginal revenue is:
[
\text{MR} = \frac{1200 – 1000}{10} = 20 \text{ dollars per unit}
]

Importance of marginal revenue

  • Pricing Decisions: Marginal revenue helps firms set optimal prices. By understanding how changes in price affect total revenue, companies can adjust prices to maximize profits.
  • Production Planning: MR is crucial for determining the optimal level of production. Firms aim to produce up to the point where marginal revenue equals marginal cost (MR = MC) to maximize profit.
  • Market Analysis: Understanding MR allows businesses to analyze market conditions and competitive dynamics. It helps in assessing the impact of market changes on revenue and profitability.

Factors affecting marginal revenue

  • Market Structure: The type of market (perfect competition, monopoly, oligopoly) affects the marginal revenue. In perfect competition, MR is constant and equal to price. In imperfect competition, MR decreases as output increases.
  • Price Elasticity of Demand: The responsiveness of quantity demanded to price changes influences MR. Inelastic demand results in higher MR, while elastic demand leads to lower MR.
  • Sales Volume: Changes in sales volume directly impact MR. Increasing sales can either increase or decrease MR depending on the price and demand elasticity.
  • Product Differentiation: The uniqueness and perceived value of a product can affect its MR. Differentiated products often have higher MR due to reduced price sensitivity.

Examples of marginal revenue

  • Retail: A clothing store calculates the MR of selling an additional shirt. If the total revenue from shirts increases by $30 with the sale of one more shirt, the MR is $30.
  • Manufacturing: A car manufacturer assesses the MR of producing and selling one additional car. If selling one more car increases total revenue by $25,000, the MR is $25,000.
  • Technology: A software company evaluates the MR of licensing its software to one more client. If the total revenue from licensing increases by $1,000 with one more client, the MR is $1,000.

Implications of marginal revenue

  • Profit Maximization: Firms use MR to determine the level of output that maximizes profit. By producing up to the point where MR equals marginal cost, companies ensure that each additional unit sold contributes to profit.
  • Competitive Strategy: Understanding MR helps businesses develop competitive strategies. For instance, firms can decide whether to lower prices to increase sales volume or maintain higher prices to maximize revenue per unit.
  • Revenue Management: MR is essential for revenue management practices, such as dynamic pricing and yield management. Companies adjust prices based on MR to optimize revenue.

  • Marginal Cost: Understanding the additional cost of producing one more unit of output and its relationship with MR.
  • Total Revenue: Exploring the overall revenue generated from sales and how it interacts with MR.
  • Price Elasticity of Demand: Learning about the sensitivity of quantity demanded to changes in price and its impact on MR.
