Profitability Cases
There are several common case types that occur in case interviews for management
consulting roles. Profitability cases are some of the most frequent ones. These
cases require a structured approach, analytical thinking, and a deep understanding
of business fundamentals. Let’s take a look at what profitability cases actually are
and how you can approach them successfully.
Profitability Cases – The Number 1 Reason for Most
Consulting Projects
One of the most common reasons why firms instruct consulting firms with their
projects is that they struggle with their profitability. As a consultant you will have
to diagnose the underlying issues, come up with potential solutions and
recommend actions to improve profitability.
As a candidate in a case interview, the task is pretty much the same, but on a
smaller scale. The good news is: Once you have understood the basic structure of
profitability cases, you can solve them no matter the industry or concrete business
scenario. The underlying concept is always the same and not very difficult.
Profitability issues always stem from falling revenues, rising costs, or both. It is
as simple as that. Your task will be two-fold: Perform a structured and quantitative
analysis of the data to isolate the problem, and then find a promising solution. In
most cases, you can use the profitability framework to structure the problem, but
make sure to not blindly apply it, but to really understand the problem at hand and
make adjustments as needed in the concrete business scenario.
The Profitability Framework – A Basic Tool to Structure
Your Profitability Case
The Profitability Framework is a fundamental tool for approaching profitability
cases. It is basically an issue tree that breaks down profitability into its key
components: revenues and costs.
In the first place, this equation is pretty straightforward and not complicated at all.
Next, it is your task to understand each side of the equation and identify the cause
for declining profitability. There could be three reasons:
1. Revenues have been declining.
2. Costs have been increasing.
3. Revenues have been declining and costs have been increasing.
(Always make sure to remember this option. It happens pretty easily that
candidates identify either revenue or cost issues as the problem, completely
focus on one side of the issue tree and forget to zoom out again, take a look
at the big picture and consider the other side of the equation as well.)
So, the first question to get an answer to is “Have revenues been declining?”,
“Have costs been increasing?”, or “Have revenues been declining and costs been
increasing? And if so, which one is the bigger problem?”. Whenever you get the
information that something has changed: quantify it! Ask by how much and in
what time period. Depending on the answer, you will know on which side of your
profitability tree you need to start your analysis. Always start with the most
relevant driver (Pareto Principle).
💡 Pro Tip: When trying to find out where to start your analysis, keep in mind to
communicate like a consultant. A Bainie would not go to the client and bluntly ask
“Have your revenues been declining?”, but rather formulate a question like “How
have your revenues been developing over the past five years?”. It may be possible
that your interviewer will then share an exhibit with you that not only contains
revenue information, but also valuable insights on product lines, geographies or
other relevant data, which you can use throughout the case.
Scenario 1: Revenues Have Been Declining
Let’s assume, the profitability problem stems from declining revenues. There are
many potential reasons for this and you need to find out which one applies in order
to come up with a solution. Most important for your analysis is to stay structured
at all times.
1. Understand How the Business Makes Revenue
To structure your analysis of declining revenues, you need to understand the
business model of the company you advise. So basically answer the questions:



How does this company make revenue?
What does the revenue consist of?
Which component of the revenue has been declining?
Understanding your client’s business model is absolutely crucial for your revenue
analysis. Only when you know which products the company sells and which
customers it serves, will you be able to give solid advice on how to solve
profitability problems.
2. Break Down the Revenue into its Single Components
Once you have understood the general business model of your client, you can go
on and break down the revenue into its components. Depending on the business
model of the company, the equation can differ.
Let’s take a look at some examples depending on different industries:
Manufacturing and Retail Industry
Revenue = Number of Units Sold × Selling Price per Unit
Number of Units Sold: The total quantity of products manufactured or sold to
customers.
Selling Price per Unit: The price at which each unit of product is sold to
distributors, retailers or customers.
Subscription-Based Services (e.g., Streaming Services, Software as a Service)
Revenue = Number of Subscribers × Monthly Subscription Fee
Number of Subscribers: The total number of customers who subscribe to the
service.
Monthly Subscription Fee: The amount charged to each subscriber on a monthly
basis.
E-commerce Industry
Revenue = Number of Transactions × Average Transaction Value
Number of Transactions: The total number of orders placed by customers.
Average Transaction Value: The average amount spent by customers per
transaction.
Advertising Industry (e.g., Digital Advertising, Print Media)
Revenue = Impressions or Clicks × Cost per Impression or Click
Impressions or Clicks: The total number of times an ad is viewed or clicked by
users.
Cost per Impression or Click: The cost charged to advertisers for each impression
or click generated.
Hospitality Industry (e.g., Hotels, Restaurants)
Revenue = Number of Rooms or Seats Occupied × Average Room Rate or Meal
Price
Number of Rooms or Seats Occupied: The total number of rooms booked or seats
occupied by guests.
Average Room Rate or Meal Price: The average price charged per room or meal.
It becomes obvious that there is no one-size-fits-all-solution for a revenue
analysis. You need to adjust your approach according to the client’s business
model and needs.
3. Analyze the Single Components of the Revenue Model
Once you have a clear picture of what the revenue of your client is composed of,
you can go on with your analysis by focusing on the component of the equation
that appears to be the problem. For example, if your client is a manufacturer with
declining revenues, you should find out if the number of units sold has been
decreasing or the selling price per unit has been lowered (or a combination of
both).
If the number of units sold has decreased, you go on with a further analysis on the
reasons behind. These can be manifold, so make sure to stay structured and use
segmentation to get to the root cause of the problem.
The segmentation you use needs to be customized to the case at hand. Make sure to
let your interviewer know your thoughts and guide him or her through the case.
That way, you will usually get valuable hints on which direction to go.
Examples for segmentations are:

Product segmentation: Product types? Price ranges? Packaging sizes?



Customer segmentation: Small / medium-sized / large businesses? Age
groups? Sex? Income groups?
Market segmentation: Geographies? Industry verticals?
Channel segmentation: Distribution channels?
If you’ve found the biggest driver of the problem, you oftentimes have to switch to
a more qualitative framework (for example the 4 Cs) to find the underlying root
cause. For example: when you have less revenue, but the price is the same and
units sold dropped, you have to find out why. Is there a new competitor on the
market? Do you have quality problems, or did you just stop a marketing initiative
that you ran for years prior to this drop?
The same procedure applies if pricing seems to be the issue for declining revenues.
“Let’s increase prices” might be an easy recommendation to give, but most likely
too easy to be valuable. It is crucial to understand first, why prices have decreased
and again, the reasons might be diverse. Make sure to use a structured approach in
order to pinpoint the exact problem.
Possible reasons and forces for decreasing prices may be:


Internal:
o Increased Supply: Overproduction or excess inventory can lead
to discounted pricing to clear out stock.
o Competitive Pricing: Aggressive pricing strategies by competitors
can force companies to lower prices to remain competitive.
External:
o Price Sensitivity of Customers: Changes in customer price
sensitivity and purchasing behavior can influence demand and
pricing strategies.
o Market Saturation: Increased competition and market saturation can
lead to price wars and downward pressure on prices.
o Economic Conditions: Economic downturns or recessions can impact
consumer purchasing power and demand for products.
o Exchange Rates: Fluctuations in exchange rates can affect
import/export prices and overall cost structure.
It may not be surprising that when looking out for the reasons of the client’s
revenue problem, staying structured is most important. Come up with solid
hypotheses and validate or neglect them in the dialogue with your interviewer and
based on the data that will be provided to you throughout the conversation. This
requires flexibility and spontaneity, so learning frameworks by heart will not help
you here. It is important to internalize the way of thinking a consultant uses and
solve cases with peers to put it into practice.

Meeting Board and simply accept one of the open invitations.
4. Recommend Actions to Get Revenues Back on Track
Once you have successfully narrowed down the problem, there is one last thing for
you to do: Come up with actions that get your profitability back on track. Most
likely these will be actions to improve your revenues (also increasing the total
value of your business), but there is a slight chance that at this point of your case,
you may have to take a look at the big picture again and consider cost cutting
measures as well.
Whatever you do, don’t get too excited before you have crossed the finish line.
Even at this final stage of your case interview, one thing is absolutely crucial. You
might have guessed it: Structure!
Don’t come up with a random list of possible solutions. Prioritize them based on
their impact and categorize them, for instance by short-term or long-term actions or
according to the difficulty of implementation.
Last but not least, remember to communicate your outcome of the analysis answerfirst. Start with what the client should do and then go on with the reasons behind.
Scenario 2: Costs Have Been Increasing
If revenues have been flat or increasing, but profitability is going down, your client
might have a cost problem. The task for you as a consultant (or candidate in a case
interview) is the same as for scenario 1: Identify the cause(s) and come up with
recommendations to solve the problem. Use a structured approach for your
analysis and communicate clearly what you are doing while working through your
case.
1. Understand the Business Model and General Cost Structure of Your Client
Before you can start to analyze the cost issue(s) of your client in detail, you need to
understand what the business is actually doing and which business model is
behind. The question of how the company makes money and which industry it is
in, already implies which cost structure may be behind. For example, a service
company will most likely have labor costs as its main cost driver while a
manufacturing company will most likely have high spendings on raw materials. So,
before you dig deeper into the cost structure of your client, get a better
understanding of its business model first.
2. Break Down the Costs into its Single Components
To start off with your cost analysis, you need to develop a structured approach
first. Segment your costs into different categories (and remember the MECE
principle while doing so). A common way to break down the costs is to
differentiate between fixed and variable costs. Fixed costs do not vary with
production or sales volume while variable costs change in proportion to the sold
goods or services.
3. Analyze the Single Components of Your Cost Structure
Once you know which component of your total costs has increased, you can go one
step further down your issue tree and focus on that component first. But always
remember to stay structured and segment as you go on identifying the root cause of
your profitability issue.
If your fixed costs appear to be the problem, you would go on by separating
different cost categories (e.g. rent or lease expenses, salaries, utilities etc.) and
taking a closer look at each one of them. Based on the business you are advising,
you should make educated guesses on which cost categories may be the most
relevant ones and start with these ones first. Let your interviewer know your
thoughts and he or she will guide you in the right direction.
If your variable costs appear to be the problem, you would go on with splitting
these costs into its components. The equation is the following:
Variable Costs = Number of Units × Cost per Unit
Number of Units is the total quantity of units produced or sold.
Cost per Unit is the cost incurred to produce one unit of product, excluding fixed
costs.
Remember to adjust the equation to the business model of your client. Which units
are we talking about? Which kind of cost per unit do we need to consider? The
equation might look different depending on whether your client is a manufacturer
or service company, so it is important to internalize these basic approaches and
adjust them flexibly to your case.
Once the composure of the variable costs is clear, you will go on by analyzing
either side of the equation. Start with the one that seems to be more relevant first.
Let your interviewer know why you would want to focus on that and receive
feedback if you are on the right track.
At this point, you will most likely be able to quantify the cause of your rising costs
and need to get more qualitative in the identification of possible reasons. Don’t
make random guesses, but think before you speak and stay structured. For
example, you could start off by differentiating internal or external reasons. If the
problem seems to be internal, you could go on by working through the value chain.
It is important that each of your steps follows a comprehensible logic.
Your procedure highly depends on the case you were given and there is no
standard framework that will help you out at this point. But don’t worry: With a
good amount of practice, you can develop the mindset of a consultant and
significantly improve your performance. We recommend at least 10-15 mock
interviews with peers before the final day, so check out our Meeting Board and
schedule meetings with like-minded candidates.
4. Recommend Actions to Improve Profitability
As a last step, identify actions that help your client get its profitability back on
track. If rising costs are your main issue, cost cutting measures may seem obvious.
However, there may be cases where rising costs are your main problem, but there
is not much you can do about it (e.g. if the prices for necessary raw materials
increase due to climate changes), so remember to keep the big picture in mind,
zoom out and do not forget that measures to increase revenues might also be a
good solution to your profitability issue.
Categorize, structure and prioritize your recommendations. What are the most
important measures and why? Make sure to communicate the outcome of your
analysis and the corresponding recommendations clearly. You have made it this
far, so stay concentrated until the end of the case and leave a lasting impression.
Scenario 3: Revenues Have Been Decreasing and Costs Have Been
Increasing
This is the worst scenario your client could possibly face. Profitability is going
down, because revenues have been decreasing and costs have been increasing.
How can you approach this case in a case interview?
It is actually quite simple. First, you need to understand which one is the bigger
problem or the problem you have more scope of action to address: Decreasing
revenues or increasing costs. Focus on that problem first and follow the procedure
you have learned in scenario 1 and 2. If you notice, you are going down the wrong
path, go up your issue tree again and take the other branch. Not validating your
initial hypothesis is always fine as long as you communicate it clearly to your
interview and stay structured in everything you do.
Profitability Case Example
Let’s take a look at a profitability case example just like the ones you might
encounter in your case interview:
Your client is a chewing gum manufacturer. The CEO of the manufacturing
company is concerned because her company is experiencing declining profitability.
Please investigate the reasons for the decline and give suggestions for
improvement.
👉 Do you want to solve the case yourself? Find it here.
1. Clarify the Problem
Start off by making sure you have understood the question correctly. A good way
to do so restating the problem: “Just so we are on the same page, our main
objective is to determine the reasons behind the decline in profitability for a
chewing gum manufacturer and provide recommendations to improve the
profitability of the business, is that correct?”
You can then go on and ask further questions to better understand the structure of
the company and industry. What is the size of the company? Which kind of
chewing gum do they sell? Who are the customers? What is the price of the
product and how does it compare with competitors? Who are the key players in the
industry?
Ask what you need to know to understand the situation of the customer and take
notes. Summarize your findings, collect feedback from the interviewer if you have
understood everything correctly and go on with the preparation of your structure.
2. Prepare your Structure
“Thank you, may I take a minute to prepare my structure?”
Based on the term “declining profitability” in the case prompt (“falling sales” or
“rising costs” can also be hints), it is valid to assume a profitability case and work
the corresponding framework as a basis for your structure. But be careful: Don’t
jump to conclusions too fast and make sure in step 1 that you have really
understood the situation of your client and prepare a structure that is customized
for it. Off-the-shelve-frameworks are never a good idea - neither in case interviews
nor in the real consulting world.
Here, we do have a profitability case that can be analyzed by using the profitability
equation to isolate and quantify the problem:
When profits go down, you either have a decline in revenue, rising costs, or both.
The best way to find the root cause is to sketch the problem as an issue tree. Start
with the more promising part, for instance, revenues - because the market is highly
competitive. Obviously, you would share that thought with your interviewer and be
on the lookout for hints. For example: “I am going to look at revenues first, since
in a competitive market like the market for chewing gums, I’d expect this to be a
big driver.”
You can further break down the profit tree like below:
Now you can start with one of the branches. Let's take the revenue side.
Try to start with the branch of the tree that also has the biggest impact on the case
solution. Share your hypothesis with the interviewer and watch out for hints if you
are on the right track.
3. Analyze the Revenue Side
To understand the revenue side of the chewing gum manufacturer, segment the
revenue streams. You can ask the interviewer whether you can segment the
revenues into its component parts. If the interviewer prompts you to do the
segmentation, you can think about different customer segments (small business /
large business, etc., age group, sex, etc…), product lines, or regions (South
America, Asia, etc.). This segmentation will help you isolate the root of the
problem. You'll be able to develop better and more targeted analyzes.
To help the chewing gum manufacturer improve her profitability, you may ask:
“What are the revenue sources?”. The interviewer tells you that all revenue comes
from two products: Flavored and non-flavored chewing gums. At this point, you
might want to know the development of sales over the past couple of years. “How
have sales figures developed over the years for both products?” She shares the
following diagram with you:
It now becomes clear that revenue is not the problem because it has grown steadily
in recent years. Therefore, it must be costs that rose significantly, leading to a drop
in profitability.
4. Analyze the Cost Side
Now explore the cost side. You know that costs can be broken down into fixed and
variable costs. You can then inquire about the breakdown of costs: "Please tell me
about the direct/indirect cost split for the products.” The interviewer hands you the
following graph:
As we know that there are two different product lines, it is advisable to calculate
their margins to check if there is a more profitable product line.
“I'd like to calculate the margins for both products; do you have information on the
different prices and costs for each of them?” The interviewer hands you the
following graph:
You calculate the margin for both products based on the following formula:
The root cause of the profitability problem becomes clear: “Analyzes show that the
product whose sales have increased (flavored chewing gum) is also the one with
lower margins due to the added flavor. Therefore, total profit margins have
decreased while sales have increased.”
5. Close the Profitability Case
After you have determined the root cause, you must develop a good logical
solution (e.g., developing a competitive response, starting a marketing initiative,
etc.)
It is important to stay structured even if you think you have reached the final stage.
Therefore, categorize your approaches, for instance on a timeline:
Short term


Negotiate with current suppliers.
Look for other suppliers (form partnerships or buy greater amounts with
batch discounts).
Long term


Vertical integration.
Release new products with better margins (e.g., low-calorie flavor gum or
tooth cleaning gum).

The client could also increase the price of the flavored gum, risking
decreasing sales if customers do not see any added value with the price rise
(high price sensitivity).
Key Takeaways - 7 Tips to Ace Your Profitability Case
with Confidence
Profitability problems are frequent in consulting case interviews and nothing to
worry about. We have summarized the 7 most important tips to keep in mind when
solving profitability cases:
1. Understanding the business model of your client and adjusting your
approach according to the company’s needs is crucial to success. The
standard profitability framework can be a good base to structure your case,
but needs to be customized individually.
2. Profitability equals revenues minus costs. Use this profit formula to build an
issue tree and tackle down the root cause of your problem (but don’t forget
about tip 1).
3. Quantify your problem and look for trends. Locate the biggest driver of your
profitability issue and prioritize it in your analysis.
4. Combine quantitative and qualitative analysis to not only identify facts, but
also understand the reasons behind.
5. Keep the big picture in mind when recommending actions to improve the
client’s profitability. The most obvious may not always be the most
sustainable and best solution in the long run.
6. Stay structured in everything you do and make sure you communicate your
thoughts clearly to the interviewer. This applies to all cases and is the most
important skill to master prior to your interviews (and the actual consulting
job as well).
7. Practice makes perfect: Solve one or two profitability cases on your own
and then make sure to connect with peers and practice together. There is no
better way to not only get into the habit of thinking like a consultant, but
communicating like one as well. You will receive valuable feedback and
improve your abilities much faster than with self-study only. Find plenty of

Direct Costs vs. Indirect Costs
Direct and indirect costs are two primary categories of expenses incurred by a
business. They are essential components of financial analysis and decisionmaking.
Direct Costs


Definition: Costs that can be directly traced to a specific product, service, or
project.
Examples:
o Raw materials
o Direct labor
o Manufacturing supplies
o Shipping costs
o Sales commissions

Understanding the distinction between direct and indirect costs is crucial for
accurate cost accounting, pricing decisions, and profitability analysis. By correctly
classifying costs, businesses can make informed decisions about resource
allocation and pricing strategies.
Fixed Costs vs. Variable Costs
Fixed Costs and Variable Costs are two primary categories of expenses that
businesses incur. They have different characteristics and impact on profitability.
Fixed Costs


Definition: Costs that remain relatively constant within a specific relevant
range, regardless of changes in production or sales volume.
Examples:
o Rent
o Salaries of administrative staff
o Property taxes
o Insurance premiums
o Depreciation of fixed assets
Characteristics:



Tend to remain unchanged over a specific range of activity.
Are often committed expenses, meaning they are difficult to adjust in the
short term.
Can be a significant portion of a business's total costs.
Variable Costs


Definition: Costs that change in direct proportion to changes in production
or sales volume.
Examples:
o Raw materials
o Direct labor
o Sales commissions
o Utilities (if usage varies directly with production)
Characteristics:

