Key Insights:
- Four Buckets Cover Every Entry Case: Test market attractiveness, competition, client fit and economics, then pick the entry mode. Tie each bucket back to the client's goal.
- Breakeven Decides Most Cases: Breakeven volume equals fixed costs divided by contribution per unit. Compare the market share you need with the share you can win.
- Entry Mode Is Part Of The Answer: Build, partner and acquire carry different costs, speeds and risks. A strong recommendation names the mode, not just "yes, enter."
A market entry framework is the structure you use when a case interview asks whether a client should enter a new market. This guide is for candidates preparing for McKinsey, BCG, Bain and other consulting interviews. You'll get the 4-bucket market entry framework, the breakeven and payback math interviewers expect, a build vs partner vs acquire comparison, and a fully worked example with numbers.
Market entry cases mirror real client work. Companies hire consultants every year to decide whether a new country, customer segment or product line is worth the investment. If you can structure that decision and back it with simple math, you show the interviewer you can do the job.
What Is A Market Entry Framework?
A market entry framework is a structure for deciding whether a company should enter a new market, and if so, how. It asks four questions: is the market attractive, can the client win against competitors, does the client have what it takes, and do the economics meet the client's goal. The answer ends with a go or no-go call and an entry mode.
Like all case interview frameworks, the market entry framework is a starting point, not a script. You adapt its branches to the prompt in front of you. A hospital chain entering a new state and a snack brand entering Japan need different questions under the same four buckets.
What Are The 3 Types Of Market Entry Cases?
Market entry cases come in three types: a new geography, a new customer segment, or a new product category. The market entry framework stays the same, but the questions you stress shift with the type.
- New Geography: "Should a U.S. coffee chain open stores in Brazil?" Stress local demand, regulation, competitors and how the client would reach customers.
- New Customer Segment: "Should a consumer bank start lending to small businesses?" Stress how the new customers buy, what they need and whether current capabilities carry over.
- New Product Category: "Should a sneaker brand launch a line of smartwatches?" Stress customer need, the client's right to win and the cost to build or buy the capability.
Name the type out loud when you recap the prompt. It tells the interviewer you already know where the risk in this market entry case sits.
What Are The 4 Parts Of The Market Entry Framework?
The four parts of the market entry framework are market attractiveness, competition, client fit and capabilities, and economics and entry mode. Before you draw them, ask for the client's goal, such as "payback within 3 years" or "$50 million in revenue by year 5." That goal becomes the pass or fail test for every bucket.
- Market Attractiveness: How big is the market, how fast is it growing, and how profitable is it? Which segments grow fastest? Are there regulatory, cultural or seasonal factors that change demand?
- Competition: Who leads, and how concentrated is the market? What do competitors charge, and how do they reach customers? How would incumbents respond if the client entered?
- Client Fit And Capabilities: Which of the client's strengths carry over: brand, products, distribution, technology or talent? What gaps would it need to close? Does entry support the client's wider strategy?
- Economics And Entry Mode: What would entry cost upfront and each year? What revenue and share can the client expect? When does it break even and pay back, and should it build, partner or acquire?
Keep the buckets MECE, so nothing overlaps and nothing is missing. Then prioritize. If the prompt says the market is large and growing, say so and spend your time on competition and economics.
How Do You Solve A Market Entry Case Step By Step?
You solve a market entry case in six steps: clarify the goal, size the market, test competition and fit, run the economics, choose the entry mode, and recommend. Each step should move you closer to a yes or no on the client's stated goal.
- Clarify The Goal: Ask what success looks like, in revenue, profit, share or payback period, and by when. Confirm the geography, segment and product.
- Size The Market: Estimate the annual value of the market and its growth. Our market sizing guide covers top-down and bottom-up methods.
- Test Competition And Fit: Look at who holds share today and whether the client has a real reason customers would switch.
- Run The Economics: Calculate breakeven volume, the share needed to break even, and the payback period.
- Choose The Entry Mode: Compare build, partner and acquire against cost, speed, control and risk.
- Recommend: Lead with the answer, give two or three reasons, name the main risk and the next step.
Stay hypothesis-driven throughout. Say what you expect to find, such as "I suspect the market is attractive but crowded, so the case turns on our right to win," then let the data confirm or change it.
How Do You Calculate Breakeven In A Market Entry Case?
Breakeven volume equals annual fixed costs divided by contribution per unit, where contribution is price minus variable cost. Divide the breakeven revenue by the market size, and you get the market share the client needs just to break even. That one number tells you fast whether the market entry plan is realistic.
Use these three formulas:
- Breakeven Volume: Fixed costs / (Price - Variable cost per unit)
- Share Needed To Break Even: Breakeven revenue / Market size
- Payback Period: Upfront investment / Annual profit (or count the years until cumulative profit turns positive)
Here is a quick check. A product sells for $50, costs $30 to make and ship, and the new market adds $8 million a year in fixed costs. Contribution is $20 per unit, so breakeven is $8 million / $20 = 400,000 units, or $20 million in revenue. If the market is worth $900 million, the client needs about 2.2% share just to cover its fixed costs.
Always say the "so what" out loud. "We need about 2% share to break even, and the third-largest player holds 6%, so breakeven looks reachable" turns a number into insight. Brush up on the arithmetic with our case interview math guide and our break-even analysis walkthrough.
Should The Client Build, Partner Or Acquire?
The client should build when it has time and the capabilities, partner when speed and local know-how count most, and acquire when it needs scale fast and a good target exists at a fair price. Every market entry recommendation should name one of these modes and say why.
| Build (organic entry) | Keeps full margin and full control, but costs more upfront than a partnership, scales slowest, and the client carries all the risk. Best when the client's brand and capabilities carry over and there is no deadline. |
| Partner (distributor, licensing or joint venture) | Fast, with less capital and local expertise on day one. The client gives up margin and some control. Best for regulated or unfamiliar markets, or when the client wants to test demand first. |
| Acquire | Fastest route to share, customers and talent. Highest upfront cost and integration risk. Best when a target is available at a price that the combined savings and growth can justify. See our M&A framework for how to test the deal. |
What Does A Market Entry Case Look Like With Numbers?
Here is a full market entry example you can practice out loud. The prompt: "Our client is a U.S. premium dog food company. It wants to enter Canada and needs its investment to pay back within 3 years. Should it enter, and how?"
Step 1: Size The Market
Start top-down. Assume Canada has about 15 million households and about 1 in 3 owns a dog, which gives 5 million dog-owning households. If each spends about $600 a year on dog food, the market is 5 million x $600 = $3 billion a year. Premium food is about 30% of that, so the client's addressable market is about $900 million.
Step 2: Set The Economics
The interviewer gives you the client's numbers. A bag sells for $50 and costs $30 to make and ship, so contribution is $20 per bag, or 40% of price. Building its own Canadian business would cost $20 million upfront and add $8 million a year in fixed costs. The client expects to win 2% of the premium segment in year 1, 3.5% in year 2 and 5% in year 3.
Breakeven is $8 million / $20 = 400,000 bags a year, or $20 million in revenue. That is about 2.2% of the $900 million premium market. Sanity check: at $600 a year, a household buys about 12 bags, so 400,000 bags means roughly 33,000 households, under 1% of Canada's dog owners.
Step 3: Test The Build Option
| Year 1 (2% share) | Revenue $18M; contribution $7.2M; minus $8M fixed = -$0.8M; cumulative after the $20M investment: -$20.8M |
| Year 2 (3.5% share) | Revenue $31.5M; contribution $12.6M; profit $4.6M; cumulative: -$16.2M |
| Year 3 (5% share) | Revenue $45M; contribution $18M; profit $10M; cumulative: -$6.2M |
| Year 4 (5% share) | Profit $10M; cumulative: +$3.8M. Payback in about 3.6 years |
The build option fails the client's 3-year test. It pays back, but about 7 months late.
Step 4: Test The Partner And Acquire Options
Now test a distributor partnership. The distributor takes $5 per bag, so contribution falls to $15 per bag (30%). In return, upfront cost drops to $8 million and fixed costs to $3 million a year. Breakeven falls to $3 million / $15 = 200,000 bags, or $10 million in revenue, about 1.1% share.
| Year 1 (2% share) | Revenue $18M; contribution $5.4M; minus $3M fixed = $2.4M; cumulative after the $8M investment: -$5.6M |
| Year 2 (3.5% share) | Revenue $31.5M; contribution $9.45M; profit $6.45M; cumulative: +$0.85M. Payback in just under 2 years |
| Year 3 (5% share) | Revenue $45M; contribution $13.5M; profit $10.5M; cumulative: +$11.35M |
Then check acquisition. Say the interviewer tells you the only premium brand for sale costs $90 million and earns $5 million a year. Payback would take 18 years. To pay back in 3 years, the deal would need about $30 million a year in profit, far more than any realistic cost savings could add. Acquisition fails the test.
Step 5: Recommend
"The client should enter Canada through a distributor partnership. The premium segment is worth about $900 million, and the partnership breaks even at about 1% share and pays back in just under 2 years, well inside the 3-year goal. Building our own business would take about 3.6 years to pay back. The main risk is giving up margin and control of the brand to the distributor. Once Canadian sales pass about $50 million, our own sales force would earn more than the partnership, so we should write the option to take distribution in-house into the contract."
That last point comes from one more line of math. Build profit is 40% of revenue minus $8 million; partner profit is 30% minus $3 million. They match at $50 million in revenue, about 5.6% share. Insights like this are what separate a good market entry answer from a great one.

What Does A McKinsey Market Entry Case Look Like?
A McKinsey market entry case is interviewer-led. The interviewer asks a series of focused questions, such as "What factors would you consider?", then hands you an exhibit or a math problem. At BCG and Bain, cases are candidate-led, so you drive from the market entry framework to the next step yourself.

What Is The Market Study Framework, And When Do You Use It?
The market study framework is the external-view cousin of the market entry framework. It looks at five areas: market, competitors, customers, company and product or service. Use it for growth and market share cases, where the question is "Why are we losing share?" or "Where can we grow?" instead of "Should we enter?"
- Market: How big is it, how fast is it growing, and which segments are growing fastest? Is there seasonality?
- Competitors: Who are the main players and what share does each hold? What do they offer, at what prices?
- Customers: Who buys, how are they segmented, and is our share in any segment rising or falling? What do they need that we don't deliver?
- Company: Where do we operate, how is revenue trending, and what capabilities do we have?
- Product Or Service: What is our product mix, at what price points, and what is in development?
Pick the framework from the question. If the client's profits fell, start with the profitability framework, which looks inward at revenue and costs. If the client is losing share in a market it already serves, start with the market study framework. If the client is deciding whether to go somewhere new, use the market entry framework.
Market Entry Vs New Product Vs Growth: Which Framework Do You Use?
Use the market entry framework when the client is considering a market it does not serve today. Use a new product framework when the client launches something new to its existing customers, and a growth framework when it wants more revenue from markets it already serves.
| "Should we sell in Germany?" | Market entry. New geography, so test attractiveness, competition, fit, economics and entry mode. |
| "Should we launch a meal kit for our grocery shoppers?" | New product. Same customers, new offering, so start with customer need and demand, then economics and launch plan. |
| "Should our airline start flying to small business travelers in a new region?" | Market entry. New segment and geography together, so treat it as entry, not growth. |
| "How do we grow revenue 20% in our current markets?" | Revenue growth. Split into existing customers, new customers and new offerings, then size each. |
| "Why is our share falling?" | Market study. Look outward at customers and competitors before you look inward. |
What Mistakes Do Candidates Make In Market Entry Cases?
The most common market entry mistake is jumping into the framework before asking for the client's goal. Without a goal, you can't say whether $10 million of profit is a win or a miss.
- Skipping The Entry Mode: Saying "yes, enter" without saying how leaves half the question unanswered.
- Forgetting Competitor Response: Incumbents may cut prices or lock up distributors. Ask how they reacted to the last new entrant.
- Treating Market Size As The Answer: A big market is only worth entering if the client can win enough share to break even.
- Ignoring The Time Frame: Payback in 4 years fails a 3-year goal, even if the business makes money.
- Reciting Every Bucket Equally: Prioritize. Tell the interviewer which bucket you think decides the case and start there.

Frequently Asked Questions
A market entry framework is a structure for deciding whether a company should enter a new market and how. It tests four areas: market attractiveness, competition, client fit and capabilities, and economics and entry mode, all measured against the client's goal.
The four parts are market attractiveness (size, growth, profitability), competition (who leads and how they would respond), client fit and capabilities (what carries over and what is missing), and economics and entry mode (breakeven, payback, and build vs partner vs acquire).
Divide annual fixed costs by contribution per unit, which is price minus variable cost. Then divide breakeven revenue by market size to get the market share the client needs just to break even, and compare it with the share it can realistically win.
The three main entry modes are build (enter on your own), partner (a distributor, licensing deal or joint venture) and acquire (buy a company already in the market). They trade off cost, speed, control and risk, so a strong recommendation names one and explains why.
A market entry framework decides whether to enter a market the client does not serve today. A market study framework looks at the market, competitors, customers, company and product to explain share loss or find growth in a market the client already serves.
McKinsey cases are interviewer-led, so the interviewer asks focused questions and hands you exhibits one at a time. BCG and Bain cases are candidate-led, so you choose the next step yourself. The market entry framework works for both.
No. Market sizing is one step inside a market entry case: it estimates how big the market is. The market entry framework then asks whether the client can win enough of that market, at what cost, and through which entry mode.
