What does marginal revenue mean?
Regarding economics and finance, marginal revenue (MR) is the extra money made when one more unit of a product or service is sold. You can calculate it by dividing the change in total revenue by the quantity of goods sold.
If a company improves its output or number of units sold, this number tells them how much extra money it will make per unit.
Businesses figure out MR to see if it’s worth investing in future revenue growth by selling more goods.
It is important to remember that more sales do not always mean more earnings. When companies look at their marginal revenue, they usually have to find a mix between maximum profit margins, price optimization, and maximum revenue.
Knowing the difference between average revenue (AR) and marginal income (MI) is also important. Around a specific time, a company averages a certain amount for each output unit.
MR may be higher than average revenue (AR) in the short term. This means that the business gets more money per unit sold. In the end, it will be the same as the AR.
Prices go down when there is more competition for a good or service. Customers will want that good or service more, but AR will stay the same.

MR is short for “marginal revenue,” and the two terms often refer to the same thing.
What’s the point of marginal revenue?
MR is crucial because it helps businesses choose whether to boost sales and production or hold prices steady.
- It’s also used to maximize income and help businesses decide how much to spend on marketing, production, adding new features, and more sales efforts.
- From the point of view of MR, there are three ways to make the connection between the price of each output unit, its revenue, and the total profitability better.
- Raise the prices. To keep growth going while making more money per unit sold, demand should be higher than supply, or price elasticity should be low. If nothing else, a drop in demand shouldn’t happen faster than the price increase.
- Cut down on extra costs. Companies can stay competitive and still profit by lowering the cost of shipping or production per unit sold. A company can make more money without changing its marginal income by becoming more efficient.
- Get the most done. Businesses can make the most money by making and selling as many units as possible in a certain amount of time. This usually happens at the cost of marginal income because it usually means discounting or lowering the price altogether. The higher number of units sold must compensate for the more minor money made per unit.
- Businesses can determine which growth tactics will work best by finding the marginal revenue and applying it to the bigger-picture profitability equation.
How to Figure Out Marginal Revenue
Equation for Marginal Revenue
At its most basic level, the marginal revenue equation shows that the number of pieces sold increases when sales go up. To find MR, divide the change in total income (TR) by the change in quantity (Q).
Here is the method for marginal revenue:
MR equals (change in TR) / (change in Q).
To correctly figure out MR:
- Figure out the change in total income (TR) by taking the new TR and subtracting the old TR.
- Find the change in quantity (Q) by taking the new quantity minus the old quantity.
- To find MR, divide the change in total income by the change in quantity.
Calculator for Marginal Revenue Case in Point
Let’s say a business sells $5 widgets. Ten items were sold for $50 by the business. The company doesn’t work in a competitive market, and the price doesn’t affect how much people want the product.
The company chooses to test whether lowering the price of a widget from $5 to $4 will lead to more sales. Before we can figure out MR, we need to know how much total income has changed:
- Change in TR = new TR + original TR
- Change in TR = ($40) minus ($50)
- Change in TR = -$10
Next, calculate the change in quantity:
- Change in Q = new Q: original Q
- Change in Q = (15) – (10)
- Change in Q = 5
Finally, divide the change in total revenue by the change in quantity to determine MR.
- MR = (-$10 / 5)
- MR = -$2
For each extra widget sold in this case, the marginal income is -$2. This means the company makes $2 less in sales for every extra widget it sells than before.
It wouldn’t make sense for the company to change its pricing plan to get more sales because price changes don’t significantly affect demand.
The Link Between Marginal Cost and Marginal Revenue
While both marginal income and marginal cost are essential for determining profitability, they differ.
What the Difference Is Between Marginal Cost and Marginal Revenue
The changeable cost a business has to pay to make and sell one more unit of output is called the marginal cost. To find it, divide the slight change in the total cost by the slight change in the amount.
Costs that change and costs that don’t change with the amount of output determine the marginal cost. Sometimes, the extra cost goes up when output goes up.
When economies of scale start to work, the marginal cost decreases.
Costs aren’t considered in marginal revenue; it’s only based on changes in overall revenue, sales prices, and product quantities.
Businesses need to know their marginal profit, which is found by taking marginal costs away from marginal income. This gives them a complete picture of whether or not selling an extra unit is a good idea.
The marginal profit can vary based on the business and the situation. In any case, if a company’s marginal profit is negative, it should consider lowering prices or stopping production of that unit to lower costs and make more money.
The Curve of Marginal Revenue
The marginal revenue curve is a graph that shows what marginal revenue looks like. It shows visually what happens to the total income when more units are sold at a specific price.
The curve’s shape depends on the type of market structure, but it usually has a downward slope. This means that as more units are sold, MR starts to go down because the company has to lower costs to keep up with demand.
Because of this, businesses usually need to lower the price of their goods to gain a larger market share. The marginal income curve considers that a product’s market price will drop to a point where it will no longer make business sense to make more of it.
How to Use Marginal Revenue
While MR seems simple (e.g., “Unit X sells for $Y, so we can expect a $Y increase in revenue”), it’s not as easy to use to figure out profitability since the price per unit doesn’t always stay the same.
For example, if Company A sells ten units at $10 each and then offers a customer “buy 10 get one free,” they will make less money than if they had sold 11 units at $10 each.
These people would make less money because they would have to cut the price to sell more units.
Say Company A finds a group of people who need its goods and are ready to pay $15 per unit.
The company would make more money if they sold fewer units at a higher price. For every extra unit they sold, they would make $15 instead of $10 in marginal income.
Should the business keep prices the same, raise them to meet demand at the higher price, or drop them to make more money overall?
The MR curve shows the answer, which shows how income changes when output goes up.
By plotting marginal revenue against added output, companies can find the strategy that brings in the most extra money. They can then adjust their production level to get the most out of that strategy.
