What is Marginal Revenue?

Marginal Revenue, often abbreviated as MR, is a fundamental concept in microeconomics and business finance. It refers to the additional revenue a business generates by selling one more product unit. In other words, the change in total revenue comes from selling one additional unit of a good or service.

To illustrate, imagine a company selling 100 product units, generating a total revenue of $1,000. If they sell one more team—making it 101 units—and their total revenue increases to $1,010, the marginal revenue from selling that additional unit would be $10.

While total revenue gives an overall picture of the money coming into a business from sales, marginal revenue provides a more granular view. It offers insights into the incremental financial benefit a company can gain from increasing its output by small amounts. 

In a competitive business environment, understanding such fine details can be the difference between profit and loss, making marginal revenue an essential tool for strategic decision-making.

Importance of Marginal Revenue in Business

Marginal revenue leads to several important benefits for businesses, as follows:

  • Determining optimal production volume: Marginal revenue enables businesses to identify where they can maximize total profits. In other words, it shows when their marginal cost equals their marginal revenue and, therefore, when they should produce the required units for maximum profit.
  • Pricing strategy formulation: By analyzing MR, companies can establish a pricing strategy that maximizes their earnings per unit sold. For example, raising prices would be beneficial if the marginal cost of producing one more unit is higher than its corresponding MR. 
  • Understanding customers: Through studying changes in demand with price variations—and correlating that data with MR figures—companies gain valuable insights into customer behavior. 
  • Price elasticity of demand: The price elasticity of demand (PED) is an essential economic concept to understand when setting prices for a product or service. By analyzing MR about PED, businesses can determine whether customers will react positively or negatively to changes in the pricing structure.
  • Identifying diminishing returns: Diminishing returns occur when producing additional units no longer results in proportional increases in revenue and profits. Marginal revenue helps companies identify this phenomenon before it significantly impacts their bottom line.
  • Making reliable profit forecasts: Companies can develop reasonably accurate forecasts of their earnings with marginal revenue data. This is especially useful for budgeting and planning long-term projects that require significant investments.

Relationship Between Marginal Revenue, Demand, and Price Elasticity

To fully grasp the concept of marginal revenue, it’s essential to understand its relationship with two other economic concepts: demand and price elasticity. 

What is Demand?

Demand refers to the quantity of a product or service that consumers are willing and able to purchase at various prices; it has an inverse correlation with marginal revenue. When demand is high, each additional unit sold increases total revenue – however, as more units are sold, and demand is satisfied, the benefit from selling more units (marginal revenue) decreases. 

What is Price Elasticity of Demand?

Price Elasticity of Demand measures how responsive the demand for a product or service is to changes in its cost. If demand is elastic, even minor price decreases can greatly affect the quantity demanded, and small price increases can significantly reduce it. 

On the other hand, if demand is inelastic, changes in cost will only bring about minimal variations in the quantity demanded. 

How Do They Correlate?

How do these concepts relate to marginal revenue? When demand is elastic, marginal revenue is positive – lowering prices can increase total revenue because the percentage increase in quantity exceeds the percentage decrease in price. 

However, when demand is inelastic, marginal revenue becomes negative – reducing prices further fails to offset the decline of each unit’s value; ultimately leading to a drop-off of total revenue.

Calculating Marginal Revenue in Easy Steps

Marginal revenue can provide valuable insights for decision-making in business. Follow these steps to find out marginal revenue:

Step 1: Understand the Marginal Revenue Formula

The formula for marginal revenue is relatively straightforward:



MR stands for Marginal Revenue,

ΔTR represents the change in Total Revenue, and

ΔQ represents the change in Quantity.

In other words, marginal revenue is calculated as the total revenue change divided by the quantity sold.

Step 2: Calculate the Change in Total Revenue

The change in total revenue (ΔTR) is calculated by subtracting the total revenue before the additional units were sold from the total revenue after the additional units were sold.

For example, if a business’s total revenue increases from $200 to $230 when they sell an additional unit, the change in total revenue is $230 – $200 = $30.

Step 3: Calculate the Change in Quantity

The change in quantity (ΔQ) is simply the number of additional units sold. In our example, since one additional unit was sold, the change in quantity is 1.

Step 4: Plug the Numbers into the Formula

After determining the total revenue and quantity change, plug these values into the marginal revenue formula.

Using the previous example, MR = ΔTR / ΔQ = $30 / 1 = $30.

The marginal revenue of selling one additional unit in this scenario would be $30.

Calculating marginal revenue provides you with a powerful tool to inform your decisions. Knowing how much extra income each additional unit of product yields can help you determine: 

Remember that other considerations like cost, market conditions, and competitors should also be part of the equation when assessing marginal revenue.

Marginal Revenue vs. Marginal Cost: A Yardstick for Business Decisions

Having learned about marginal revenue, it’s important to introduce another closely related concept that often goes hand-in-hand with it in business decision-making: Marginal Cost. Marginal Cost refers to the change in total cost that arises when the quantity produced changes by one unit. Essentially, it’s the cost of making one additional product unit.

The Profit Maximizing Condition

In a perfectly competitive market, a business aims to set its production level such that marginal revenue equals marginal cost (MR = MC). This is known as the profit-maximizing condition. Here’s why:

  • If the marginal revenue of selling an extra unit exceeds the marginal cost, the company can increase profits by increasing production.
  • Conversely, if the marginal cost of producing an extra unit is higher than the marginal revenue obtained, the company can increase profits by reducing production.

Practical Applications of Marginal Revenue in Business Strategy: A Case Study

Let’s imagine you’re managing a company that manufactures laptops. Your brand is well-received in the market, and you’re considering ramping up production. To help you decide, you start calculating your marginal revenue and marginal cost.

When MR > MC: Go Ahead with More Production

At first, you find that it costs your company an extra $500 to produce one additional laptop, including parts, labor, and other variable costs. You generate an additional $600 in revenue when you sell this laptop. So, you’re earning $100 more for each additional laptop you produce and sell. This extra $100 says, “Hey, keep the production going!”

When MR < MC: Not Good for Your Business Profitability

But, as with all good things, there comes a point where this no longer holds. As you further increase production, your costs are creeping up. The price of parts starts to rise due to the increased demand you’re creating, and you may even need to pay overtime to your workers to meet the production demand.

Suddenly, you find that producing one more laptop costs you $700. Yet, because of your established pricing structure, you’re only generating $600 from selling that additional laptop. Now, instead of making an extra $100 per laptop, you’re losing $100. The numbers tell a different story: “Hold on, it’s time to stop ramping production.”

Aim for MR = MC to Maximize Profit

In essence, you’ll want to keep increasing your laptop production as long as your marginal revenue (the additional income from selling one more laptop) exceeds your marginal cost (the additional cost to produce that extra laptop). When these two values are equal, you’ve hit your sweet spot. Beyond this point, producing more laptops won’t bring in extra profits, and you’re starting to lose money on each additional unit produced.

It’s a delicate balancing act, but understanding this interplay between marginal cost and marginal revenue can be a game-changer for any business aiming for profit optimization.

5 Pitfalls in Interpreting Marginal Revenue and How to Navigate Them

While marginal revenue is a powerful tool in business strategy, it is essential to remember that its application is challenging. Misinterpreting marginal revenue can lead to strategic missteps and missed opportunities. Here are five common pitfalls to avoid and tips on how to navigate them:

  • Ignoring market conditions: Market demand is never static – it shifts with changing economic conditions, trends, and consumer preferences. Companies must consider these dynamics when making pricing or production decisions – not just marginal revenue figures.
  • Not accounting for competitive forces: Businesses don’t operate in a bubble – competitors’ actions, like pricing changes or new product launches, can impact their marginal revenue. Companies must stay vigilant and adjust strategies to stay ahead of the game.
  • Underestimating fixed costs: Marginal revenue may show the additional revenue from selling more units, but it doesn’t account for the fixed costs of running a business. To ensure profitability, businesses must consider these costs when making production and pricing decisions.
  • Relying too heavily on historical data: Historical data can be invaluable – yet relying solely on it to make future decisions is dangerous. Markets evolve, consumer preferences change – and companies need to take current trends and forecasts into account as well.
  • Ignoring non-monetary factors: Producing more isn’t always about increasing revenue; other considerations, such as environmental concerns or employee overwork, impact a company’s reputation. Companies must weigh these non-monetary factors alongside potential revenue gains.

To navigate these pitfalls, businesses should adopt a comprehensive approach to decision-making, considering various factors alongside marginal revenue. Regular market analysis, competitor monitoring, cost management, and forecasting are all critical components in developing an effective and adaptable business strategy.

Importance of Continuously Monitoring Cost Factors

Monitoring cost factors is crucial for informed decision-making and strategic planning, including calculations related to marginal revenue. Here’s how continuous cost monitoring can benefit businesses:

  • Understand production costs: Tracking costs over time helps identify trends, anticipate changes, and understand their impact on marginal revenue.
  • Monitor time factors: Changes in production time can affect labor costs and overheads, thereby impacting marginal cost and revenue. Try using advanced time-tracking solutions like to keep track of time and project costs through detailed reports.

  • Keep track of material costs: Regular monitoring allows businesses to anticipate cost changes due to fluctuating material prices and adjust their strategies accordingly.
  • Analyze overhead costs: Regular analysis helps businesses understand how these costs affect their marginal cost and revenue.
  • Consider external factors: Keeping an eye on external factors like regulatory changes or market demand can help businesses anticipate cost changes and adjust their strategies.

In short, continuous cost monitoring helps businesses anticipate changes, adjust their strategies, and make data-driven decisions, optimizing their pricing and production strategies for maximum profitability.
