This page is one part of the case interview guide to consulting cases.

Why interviewers ask this

A market entry case shows whether you can turn a vague "should we expand?" into an ordered set of tests and stop when a test fails. One prep site reports that candidates are very likely to meet at least one market entry case, especially in first rounds at the large strategy firms (as of October 2026), though no firm publishes how often it appears.

Bain's official guidance says the interviewer is looking for something other than a single answer: "We're not looking for a single right answer; we're looking for how you think, structure problems, and build on ideas as the conversation evolves." A weak answer lists every framework word it remembers. A strong answer clarifies the goal, tests the market first, says what would change the recommendation and ends with a clear yes, no or yes-with-conditions backed by numbers.

Market entry case from first principles

Entry mode

An entry mode is the way a company gets into a new market, such as exporting, licensing, franchising, a joint venture, an acquisition or building its own operation, and each mode trades control against speed and the money committed up front.

Break-even share

Break-even share is the smallest share of a market at which a company's yearly contribution, which is revenue minus variable costs, equals its yearly fixed costs, so any share above it earns a profit.

Right to win

A right to win is a specific advantage, such as a stronger product, lower cost, a known brand or better distribution, that explains why a company would beat the competitors already in a market.

In plain words

Imagine you sell cakes and want to open a stall in a town you do not know. First you ask whether enough people there buy cakes and whether stalls make money. Then you look at the other stalls and ask what you do better. Next you decide how to start: rent a corner of an existing stall, buy a stall someone already runs, or build your own. Last you check that the takings cover the rent.

The analogy breaks in one place. A company often has a board and shareholders waiting for the answer, so the interviewer wants a firm recommendation with the risks named.

In one precise sentence: a market entry case is a decision problem where you compare the expected profit of entering, in a chosen way, against the cost and risk of doing so.

Step 1: Clarify the goal and the market

Start by agreeing what the client wants. Bain's tips begin with "Clarify the objective", then "Structure your thinking", "Think aloud" and highlighting key numbers (Bain, as of October 2026). Ask which company and product, which market, what the goal is (profit, share or a strategic foothold), the time horizon and the budget.

The market need not be a country. A prep site notes that the case asks whether a company should enter a new market, and the market can be a geography, a product category or a sales channel.

Input: the prompt and your questions. Output: one written sentence, such as "Should this company enter this market, by when, to reach what goal?" Say it back to the interviewer. You now have a target to test in the next step.

Step 2: Test whether the market is profitable, not just big

Check size, growth, profit margins and barriers to entry, which are the obstacles that make it hard for a newcomer to get started. A prep site gives the cut-off rule: "If the market is small, shrinking, or unprofitable, there is usually no reason to go further." Estimate size with market sizing.

Big is not the same as profitable. Porter (2008) explains why a fast-growing industry is not always a profitable one. Porter's five forces is a framework that says an industry's profit depends on rivalry among existing competitors, the power of suppliers, the power of customers, the threat of substitutes and the threat of new entrants, because these forces decide how the value the industry creates is divided.

Input: market facts. Output: a verdict. Go on only if the market is large enough and the forces leave room for profit.

Step 3: Test the competition and the right to win

Now ask who already serves the market and how they would react. Look at their share, their prices, their strengths and how easily a newcomer could be copied.

Then look at the company itself. A right to win is the reason this company would beat those rivals.

Ask what the company is good at that transfers: product, cost, brand, technology, relationships or distribution. Ask what it lacks locally. A market can pass Step 2 and fail here.

Input: competitor facts and company strengths. Output: a statement such as "attractive market, but we lack distribution", which becomes the main risk and shapes the mode in Step 4.

Step 4: Choose the entry mode

Modes sit on a spectrum: exporting, licensing and franchising, then alliances and joint ventures, then acquisition and greenfield (Global Marketing open textbook, as of October 2026; Umbrex, as of October 2026). One framework scores them on "control vs. resource commitment (or risk)", and sometimes on speed.

A joint venture is a business owned and run together with a local partner. A greenfield entry is a wholly owned operation built from scratch. An acquisition is the purchase of an existing local company. The textbook lists fast entry and existing channels as advantages of acquisition, with high upfront cost and integration issues as disadvantages. For greenfield it lists maximum control and local presence against high investment, risk from unknowns and a longer time to set up.

Theory adds a condition. One academic paper finds a firm may prefer a joint venture to an acquisition, and an acquisition to greenfield, provided the first two have sufficiently low fixed costs.

Step 5: Check the numbers and recommend

Turn the story into arithmetic. Market size is customers times the share who buy times yearly spend per buyer. Revenue is your share times market size. Contribution margin is the share of revenue left after variable costs, so contribution is revenue times that margin, and profit is contribution minus fixed costs. Payback is the upfront investment divided by yearly profit, and break-even share is fixed costs divided by market size times margin. Simple payback ignores ramp-up years and the time value of money, so say that it is a first-pass check. Practise the arithmetic with case math drills; the same logic of revenue, cost and profit appears in the profitability case walkthrough.

Finish with a recommendation: enter, do not enter, or enter under named conditions. Add two or three risks and the next steps, such as testing demand in one city first.

A market entry case runs in five steps from clarifying the goal to checking the numbers, and each step ends with a verdict that lets you stop or continue.

Step-by-step description

1. Agree what the client wants and which market.
2. Size, growth, margins and barriers decide go or stop.
3. Competitors and the company's strengths.
4. Trade control against speed and money committed.
5. Break-even share, payback, then recommend.

• A market entry case runs in five steps from clarifying the goal to checking the numbers.
• Each step ends with a verdict that lets you stop or continue.

Worked example

Take an illustrative packaged-coffee brand that wants to enter one new country. Every input below is made up for the exercise, and the arithmetic is in a script.¹ The country has 2,000,000 households, 20% of them would buy, and each buying household spends 60 currency units a year. The market is therefore 24,000,000 currency units a year (illustrative).¹

Suppose the company enters by building its own operation and reaches a 10% share. Revenue is 2,400,000, a 25% margin gives 600,000 of contribution, and fixed costs of 300,000 leave a yearly profit of 300,000 (all illustrative).¹ With an upfront investment of 1,800,000 the payback is 6.0 years.¹ Break-even share is 300,000 divided by 24,000,000 times 25%, which is 5.00%, so a 10% target leaves room.¹

Now compare modes with made-up assumptions.¹ Exporting needs 300,000 up front, reaches a 6% share at an 18% margin and has 100,000 of fixed costs. A joint venture needs 900,000, reaches 9% at 22% with 200,000 of fixed costs. An acquisition needs 3,000,000, reaches 14% at 25% with 400,000 of fixed costs. Yearly profit is then 159,200 for exporting, 275,200 for the joint venture, 440,000 for the acquisition and 300,000 for greenfield. Payback is 1.88 years for exporting, 3.27 for a joint venture, 6.82 for an acquisition and 6.0 for greenfield, and break-even shares are 2.31%, 3.79%, 6.67% and 5.00%.¹

The acquisition earns the most each year yet pays back slowest, because it commits the most money. The ranking depends on the goal agreed in Step 1.

Text description of the diagram

• Illustrative payback is 1.88 years for exporting and 6.82 years for acquisition.
• Greenfield pays back in 6.0 years.

Trade-offs and edge cases

Acquisition gives fast entry and existing channels, but brings a high upfront cost and integration issues, and greenfield gives maximum control but is slow and risky. Exporting commits little money but leaves you with a thin local presence. A joint venture shares control with a partner, which helps with local knowledge and adds the chance of disagreement.

Text description of the diagram

• Acquisition gives fast entry and existing channels but brings high upfront cost and integration issues.
• Greenfield gives maximum control but is slow and risky.

Edge cases change the answer:

• Attractive market, no right to win. Recommend a partnership or an acquisition that buys the missing capability, or recommend not entering.
• Profitable but crowded. Porter's point is that strategy can be viewed as finding a position where the forces are weaker, so look for a niche or a channel rivals ignore.
• Firm style differs. One prep author says McKinsey runs interviewer-led cases, and BCG (Boston Consulting Group) and Bain lean more candidate-led (as of October 2026). Reported practice differs, so follow the interviewer's lead.

Another prep site says most market entry cases should include four areas in some form: market, competition, capabilities and financials. That is a point for adapting a structure, not reciting one. Adapt your structure to the prompt, as in case interview frameworks that still work in 2026.

How to answer it in an interview

The spoken structure: confirm the goal, give the ordered tests, name where you would stop, and end on the numbers. Rehearse it with the 20 original practice cases.

Common mistakes

• "The market is growing fast, so we should enter." (wrong) Growth does not mean profit. (right) "Growth is encouraging, but I need margins and the strength of the five forces before I say it is attractive."
• "I will use my market entry framework." (wrong) Reciting a template ignores the prompt. (right) "Here is a structure built for this client's goal."
• "Entering means going to another country." (wrong) It can also be a product category or a channel. (right) "I will confirm what kind of market we mean."
• "Acquisition is the fast option, so I recommend it." (wrong) It ignores cost and integration. (right) "Acquisition is fast but expensive, with integration risk; I would recommend it only if speed is the priority."
• "I recommend entering." (wrong) With no numbers, it is an opinion. (right) "I recommend entering via a joint venture: in this illustrative case it pays back in about 3.3 years, roughly half the acquisition's 6.8, and breaks even at a 3.8% share against a 9% target, while reaching more share than exporting."

Follow-up questions

How do you structure a market entry case?

Clarify the goal, test whether the market is profitable, test the competition and the company's right to win, choose the entry mode, then check break-even and payback. Prep sites use a similar four-part skeleton plus an entry-mode step; it is a convention rather than an official firm framework.

What is the difference between a market entry case and a market sizing case?

A market sizing case asks only how big a market is. A market entry case uses that size as one input and goes on to decide whether and how to enter. See market sizing for the estimating technique.

Which entry mode should you recommend?

Recommend the one that fits the goal: exporting for low commitment, a joint venture for shared risk and local knowledge, an acquisition for speed and existing channels, greenfield for control. Back the choice with payback and break-even share, as in the worked example.

What if the market is attractive but the company has no right to win?

Say so plainly. Then offer options: partner with someone who has the missing strength, acquire it, or decline to enter. A clear "not yet, and here is why" is a valid result.

How do you finish a market entry case?

Give a recommendation in one sentence, the two or three numbers that support it, the main risks and the next step. Do not restate the whole case.
