How to Find Marginal Revenue: The Ultimate Guide

May 31, 2022

As a business owner, you’re always looking for ways to increase your revenue. One way to do this is by understanding and calculating your marginal revenue. This guide will show you how to find marginal revenue for your business and explain why you need to calculate it.

Marginal revenue is the additional income that your business earns by selling one more unit of a good or service. In other words, it’s the amount of money that you make from each sale after all fixed costs have been covered.

So if you want to learn how to find marginal revenue and more, read on!

Marginal Revenue Definition

The MR is the amount of profit you make from each unit you sell. The MC is the cost of producing that product.

At the break-even point of marginal cost and revenue, it is time to stop selling. At this point, any additional production will not result in any benefits as there would be no revenue to be made.

At the point where marginal cost and revenue meet, it is no longer beneficial to produce more goods as there is no revenue to be made. This break-even point marks the end of production.

The company should continue to produce as long as the marginal revenue from the additional production is greater than the marginal cost.

It is important to keep in mind that marginal costs can differ from product to product and may even fluctuate at various production levels for the same product. The financial ratio calculation will not be affected by the output level.

The Law of Diminishing Returns states that as production increases, the incremental revenue from each additional unit decreases.

In a perfect competition, businesses will continue to produce until their revenues equal their costs.

Marginal revenue is the term used in accounting to describe the revenue a company earns by selling one additional unit. The marginal revenue can also be used to show how much it costs a company to produce one additional unit.

Marginal revenue is an important concept for company management because it helps them determine the demand for their products, plan production schedules, set product prices, and calculate sales percentages.

Why does your business need to calculate marginal revenue?

To maximize profits, companies must keep track of their net profits, or their total revenue minus their total costs. They must also determine their optimal price point, or the price that maximizes their total sales.

To set their pricing, they need to figure out their profit margins and the optimal price to charge.

1. Understand the revenue impact that an additional unit sale has on your business.

Increasing the number of products and services you sell will generally lead to a higher overall profit, more sales, and higher costs.

Because it’s a measure of how much additional money you can make by selling more products, it’s crucial that you understand the concept of marginal revenue from sales.

The Law of Diminishing Returns says that as productivity rises, efficiency will decline. This basically means that your company has reached its maximum capacity.

A company makes profit as long as their Marginal Revenue (MR) is greater than their Marginal Cost (MC). Once their MR. is equal or less than their M.C., they stop making more sales.

2. Understand the relationship between sales and market demand

Marginal Revenue is the relationship between the sale of one unit, the demand for that item, and the level of competition in that market.

In order to achieve growth and profitability, it is important to understand the relationship between the two.

The market demand is for your products and services, and your sales are for those same products.

In a market where competition is fierce, the profit you make from selling your product is equal at all production volumes.

In a market where there are many competitors, companies can sell as much of their product as they want at any given price point. Since there is little to no competition, there is no need to lower prices in order to increase sales volume.

As more competitors enter the market, they will decrease their pricing in order to attract customers. This is because these competing companies require a lower price point in order to increase their sales volume. On the other hand, because these companies cannot set their own prices, they can sell their goods or services at any price point, and price increases are not required to increase their volume.

The total revenue will decrease below $0.

3. Profit maximization

Businesses need to keep increasing their production as long as each unit of output is worth more than the cost of making it.

Companies should produce until their extra revenue from the extra product produced is equal to the extra cost of that production.

A company can produce no more profit than it has at the MC = MR point. Beyond that point, it’s not in the company’s best interest to produce any more.

Marginal Revenue Calculation

The marginal revenue (or MR) is the increase in revenue from selling one more unit

Marginal revenue formula: MR = ΔTR/ ΔQ

How to find marginal revenue

Assuming you sell all 15 dog sweaters this year, that would be a best-case scenario!

If you reduced your sweater prices to $35, you would make $280 in revenue and 8 more sales than you did the previous year. Your profit would be $10.

3 additional sweater sales $30 increase in monthly revenue.

To calculate marginal revenue, you need to find the change in revenue when you sell one more unit. In the previous example, you lowered your selling price by $5, sold one extra sweater, and made an extra $20 in revenue. Your marginal revenue was $20.

You sold three more sweaters this time, but at a lower sale price. Your total profit was $10.

It’s time to ask yourself if it was worth your effort to only get an extra $10 for each sweater. Remember, you sold 5 sweaters last year for $50 each.

If you sold all 15 of your sweaters that were priced at $25 each, you’d make $225.

Your total profit would be -$2.50:

$25 decrease in revenue from 10 additional sweater sales

It’s tough to stomach the fact that you’re actually losing money on sweaters. You’re literally spending $2.50 on each garment just to get them out of your warehouse!


Now you know how to find marginal revenue for your business. Calculating your marginal revenue can help you understand where your business stands and where it has potential for growth. So go ahead and make a difference in your business!
