10 Steps to Successfully Calculating Your Marginal Profit
Max 9 min read What is marginal profit?
Marginal profit is a concept in microeconomics that refers to the increase in a company’s profit from selling one additional unit.
It is expressed as the difference between marginal revenue (the increase in revenue from one additional unit) and marginal cost (the increase in the cost of producing one additional unit).
Companies use this concept to decide whether to expand, contract, or stop production based on the projected profit.
Marginal profit is beneficial for managers as it helps them to determine the optimal level of production and the point at which they should stop production (shutdown point).
Marginal profit equals the revenue earned from making one additional unit of product, less the cost incurred in making the additional unit.
This helps in deciding whether to increase capacity or not.
Why is calculating marginal profit important?
Calculating marginal profit is an important part of financial and management accounting.
By understanding the impact of selling one more unit on their overall income, businesses can use this information to make decisions about production levels, pricing, and more.
Marginal profit is calculated by taking the difference between marginal revenue and marginal cost.
This analysis can help businesses determine whether increasing or decreasing the output level is profitable.
This guide will explore marginal revenue, its relationship with other metrics, how to calculate it, and why it is important.
The 10 steps to successfully calculate your potential marginal profit
Let us cover the steps to calculate your marginal profits by understanding the marginal cost and revenue concepts.
Step 1: Calculate total revenue
It is important to calculate total revenue to understand a business’s overall performance.
Total revenue measures the sales or income for a specified number of items or services.
It refers to the total amount customers have paid for a provided set of goods or services.
By calculating total revenue, businesses can better assess the amount of money they bring in and how much they make from each sale.
- Calculate the total revenue by multiplying the number of items sold by the price of the items. The formula is Total Revenue = Price x Quantity.
- Calculate the marginal revenue by dividing the total revenue change by the quantity sold. The formula is Marginal Revenue = Change in Total Revenue / Change in Quantity Sold.
- Calculate the average profit by subtracting the total cost from the total revenue and dividing it by the total quantity. The formula is Average Profit = (Total Revenue – Total Cost) / Total Quantity.
Step 2: Calculate total costs (fixed + variable costs)
It is important to calculate total costs to ensure that a business is maximizing its profitability.
By calculating marginal cost and marginal profit, businesses can determine a break-even point where they can produce more items and generate more revenue while maintaining profitability.
Factors such as labor costs, cost of supplies, interest on debt, and taxes must all be factored into the total costs.
Additionally, businesses must also consider fixed costs, as these one-time expenses can significantly impact overall profitability.
By understanding the total costs of producing items, businesses can make more informed product decisions for greater profitability.
- Calculate the total fixed costs. This cost remains constant regardless of the volume produced and is not affected by changes in production levels.
- Calculate the total variable costs. This is the cost that changes with production volume and is therefore affected by changes in production levels.
- Calculate the total cost. To calculate the total cost, add the total fixed costs to the total variable costs. The total cost equals the total fixed costs plus the total variable costs, which can be calculated by multiplying the variable cost per unit by the quantity produced.
Step 3: Calculate marginal revenue
Calculating marginal revenue is important because it allows businesses to measure the impact of selling one more unit on their overall income.
Companies can understand consumer demand, plan production schedules, and set optimal product prices by understanding the revenue generated from each additional sale.
Additionally, marginal revenue analysis can help companies identify the point of profit maximization and make informed decisions that will help them maximize their profits.
- Calculate the change in total revenue by subtracting the revenue figure before the additional unit was sold from the total revenue.
- Calculate the change in quantity by subtracting the quantity figure before the additional unit was sold from the total quantity sold.
- Calculate marginal revenue by dividing the total revenue change by the quantity change.
- Marginal Revenue = Change in Total Revenue / Change in Quantity Sold
Step 4: Calculate marginal profit
To calculate marginal profit, we must first calculate the marginal revenue and cost of producing one additional unit.
The marginal revenue is the revenue received from selling one additional unit, and the marginal cost is the cost incurred from producing one additional unit.
Once we have these two values, we can calculate the marginal profit by subtracting the marginal cost from the marginal revenue.
The equation for calculating marginal profit is as follows:
- Marginal Profit = Marginal Revenue – Marginal Cost
We must first determine the marginal revenue and cost associated with each additional unit produced to use this equation.
Once we have these values, we can plug them into the above equation and calculate the marginal profit.
Step 5: Determine the optimal sales volume level
The optimal sales volume level for a potential marginal profit calculation can be determined through a few steps.
First, we need to determine the average selling price (ASP) and the sales quantity for the previous year. We can calculate the total revenue by multiplying the ASP by the quantity sold.
From there, we can calculate the change in revenue and quantity for each year by subtracting the prior period value from the end-of-period value.
Next, we need to use the “Goal Seek” function in Excel to adjust the quantity sold step function to make the Year 3 cell equal to zero (or as close to it as possible).
This will return a value for the quantity step function that gives us the optimal sales volume level.
Given our parameters, we can confirm that our company’s marginal profit in Year 3 is near zero.
Finally, we can calculate the marginal profit for Years 2 to 4 by subtracting the marginal cost from the marginal revenue.
This will give us an indication of the point at which our company’s profits are maximized.
Hypothetically, if our company’s cost structure were to be adjusted and its margin profile was to improve by implementing cost-cutting measures or by increasing the average selling price (ASP), the optimal quantity would adjust accordingly.
Step 6: Calculate the revenue impact of each additional unit sold
Calculating the revenue impact of each additional unit sold is important because it allows businesses to accurately determine the impact of increasing production levels on their overall profits.
Knowing the marginal revenue can also help businesses assess whether increasing production is worth it, as it also considers the marginal costs incurred.
Understanding marginal revenue is also essential for businesses to manage their growth and development, as it is subject to the law of diminishing returns which states that any production increases will result in smaller increases in output.
Finally, calculating marginal revenue is key to understanding whether the amount earned by raising profits offsets the losses incurred from selling fewer items.
- Calculate the change in revenue by subtracting the total revenue from Year 1 from the total revenue from Year 2.
- Calculate the change in quantity by subtracting the number of units sold in Year 1 from those sold in Year 2.
- Calculate the marginal revenue by dividing the change in revenue (Step 1) by the change in quantity (Step 2).
- The result from Step 3 will give you the marginal revenue of each additional unit sold.
Step 7: Calculify the profit margin at different sales volumes
You must first calculate the total revenue and cost to calculate the profit margin at different sales volumes.
The total revenue is calculated by multiplying the number of products sold by the price per product.
The total cost can be calculated by adding the fixed cost (e.g., machine cost) and the variable cost (e.g., material and labor cost).
Once you have these values, you can calculate the total profit by subtracting the total cost from the total revenue and then calculate the average profit by dividing the total profit by the number of products sold.
To calculate the marginal profit, consider the marginal revenue and cost.
The marginal revenue is the incremental increase in revenue for each product sold.
It can be calculated by multiplying the quantity sold by the price per product.
The marginal cost is the incremental increase in expenses for each product sold.
It can be calculated by multiplying the quantity sold by the cost per product.
Finally, you can calculate the marginal profit of each product by subtracting the marginal cost from the marginal revenue.
To maximize profits, you can use the “Goal Seek” function in Excel to adjust the quantity step function to maximize the profit.
Step 8: Calculation of marginal cost curve and marginal revenue curve
The marginal cost curve (MCC) and marginal revenue curve (MRC) can be calculated by taking the derivative of the cost and revenue functions, respectively.
For example, the equation for the MCC is given by the derivative of the cost function, and the derivative of the revenue function gives the equation for the MRC.
First, take the derivative of the cost function to calculate the MCC.
This can be written as MCC=dC(x)/dx. In this equation, d is the derivative operator, C(x) is the cost function, and x is the number of units produced.
Next, take the derivative of the revenue function to calculate the MRC.
This can be written as MRC=dR(x)/dx. In this equation, d is the derivative operator, R(x) is the revenue function, and x is the number of units produced.
The marginal cost and revenue curves can then be graphed to show the relationship between cost, revenue, and the number of units produced.
These curves are often used to find the optimal output level for a company, as production beyond the optimal level will result in losses.
Step 9: Understand the relationship between sales and market demand
Understanding the relationship between sales and market demand can help you calculate your potential marginal profit by allowing you to understand how much revenue will be generated from each additional unit sold.
Knowing your marginal revenue can help you determine the optimal price point to maximize your profits and help you decide how much to produce to meet demand without overproducing.
Additionally, it can help you determine how introducing new competitors or changes in market demand will affect your profitability.
Step 10: Run an empirical analysis to validate your hypothesis
It is important to run an empirical analysis to validate any hypothesis when making important business decisions.
Running an empirical analysis allows you to analyze the numbers and understand their formulas to make informed decisions that can boost profits.
For example, suppose you are looking to optimize marginal profit. In that case, you can use empirical analysis to calculate marginal revenue to determine the impact of selling one more unit on your overall income.
This will help you identify whether increasing production levels will increase profits, helping you manage your growth and development.
