Insurance case interviews are consulting case interviews in which the business problem involves an insurance company. These cases test your ability to apply structured thinking and business analysis to problems like declining profitability, market entry, pricing strategy, or mergers within the insurance industry.

You do not need to be an insurance expert to pass these cases. However, understanding the basics of how insurance companies operate, make money, and compete will give you a significant advantage over other candidates.

In this guide, we will cover the insurance industry from the ground up, walk through the most common insurance case types, give you tailored frameworks, and provide practice cases so you can prepare with confidence.

But first, a quick heads up:

McKinsey, BCG, Bain, and other top firms accept less than 1% of applicants every year. If you want to triple your chances of landing interviews and 8x your chances of passing them, watch my free 40-minute training.

What Is an Insurance Case Interview?

An insurance case interview is a standard consulting case interview where the client or business situation involves an insurance company. The interview format is identical to any other case interview. You will receive a business problem, structure a framework, analyze data, and deliver a recommendation.

Insurance cases appear at both generalist firms like McKinsey, BCG, and Bain and at firms with dedicated insurance practices like Oliver Wyman, Deloitte, and EY. According to Glassdoor data, Oliver Wyman gives insurance cases more frequently than any other firm because insurance and financial services are among their largest practice areas.

If you are interviewing for a financial services or insurance practice, you should expect at least one insurance case during your interview rounds. Even at generalist firms, insurance cases show up because the insurance industry is a $7 trillion global market that generates enormous consulting demand. If you are new to case interviews in general, start with our complete beginner's guide to case interviews before diving into insurance specifics.

What Does the Insurance Industry Look Like?

The global insurance industry generated over $7 trillion in gross written premiums in 2025, according to Statista. The United States alone accounts for roughly $2.6 trillion of that total, making it the largest insurance market in the world. Understanding the basic structure of this industry will help you ask better clarifying questions and build stronger frameworks in your case interviews.

What Are the Major Segments of the Insurance Industry?

The insurance industry is divided into several major segments. Each segment has different business models, risk profiles, and competitive dynamics. Here are the five segments you are most likely to encounter in a case interview.

Segment	What It Covers	Major Companies
Life Insurance	Death benefits, annuities, retirement products	MetLife, Prudential, New York Life
Property & Casualty (P&C)	Auto, homeowners, commercial property, liability	State Farm, Allstate, Progressive, GEICO
Health Insurance	Medical, dental, vision, prescription drug coverage	UnitedHealth, Anthem, Cigna, Aetna, Humana
Reinsurance	Insurance for insurance companies (risk transfer)	Munich Re, Swiss Re, Berkshire Hathaway Re
Specialty Insurance	Cyber, marine, aviation, professional liability	Lloyd's of London, Chubb, AIG, Markel

Property and casualty is the largest segment by premium volume in the U.S. and is where most insurance consulting cases are set. Health insurance cases are also common, especially at firms with healthcare consulting practices.

How Do Insurance Companies Make Money?

Insurance companies generate revenue through two main channels: underwriting income and investment income. Understanding both is essential for solving insurance case interviews because many cases hinge on one or both of these levers.

Underwriting income is the difference between premiums collected and claims paid out plus operating expenses. When an insurer collects more in premiums than it pays in claims and expenses, it earns an underwriting profit. The key metric here is the combined ratio.

A combined ratio below 100% means the insurer is making an underwriting profit. A ratio above 100% means it is losing money on underwriting. According to Fitch, the U.S. P&C industry is projected to have a combined ratio of 96% to 97% in 2026, indicating modest underwriting profitability.

Investment income comes from investing the premiums that insurers collect before they need to pay claims. This pool of money is called the "float." Insurers invest the float in bonds, stocks, real estate, and other assets. In 2025, U.S. insurers earned average investment yields of roughly 4.2%, according to industry reports. Some insurers, like Berkshire Hathaway, have built their entire business strategy around maximizing investment returns on float.

This dual revenue model means that an insurer can lose money on underwriting and still be profitable overall if investment income more than offsets the underwriting loss. This is a critical insight for case interviews because it means profitability analysis must examine both sides.

What Are the Key Trends Shaping the Insurance Industry?

You do not need to memorize every trend, but knowing a few will help you sound credible and ask sharper questions. Here are the trends most relevant to case interviews.

Climate and catastrophe risk: Global insured losses from natural catastrophes have exceeded $100 billion annually for six consecutive years as of 2025, according to Swiss Re. The 2025 California wildfires alone caused an estimated $40 billion in insured losses. This trend is driving premium increases, market exits in high-risk areas, and massive investment in AI-driven risk modeling.

AI and automation: Insurers are deploying AI across underwriting, claims processing, and fraud detection. Chubb announced plans to reduce its workforce by roughly 20% over three years through AI deployment. AI is transforming how insurers price risk, assess damage, and process claims.

Cyber insurance growth: With 25% of companies experiencing a cyber event in the past year according to the 2025 Travelers Risk Index, cyber insurance has grown from a niche product into a core P&C segment. This is a common topic for market entry or new product cases.

Insurtech disruption: Technology-first insurance companies like Lemonade and Root are challenging traditional distribution models with direct-to-consumer, app-based insurance purchasing. Insurtech funding averaged over $1 billion per quarter in 2025.

Affordability pressure: Rising premiums are becoming a political and consumer issue. Family health coverage now averages $27,000 annually, and homeowner insurance deductibles increased 22% in 2025 according to MATIC. This trend drives consulting cases around cost reduction and product redesign.

What Types of Insurance Cases Come Up in Consulting Interviews?

Insurance case interviews cover the same case interview types as cases in any other industry. However, certain case types appear more frequently in an insurance context. Here is a breakdown of the most common ones.

Case Type	Example Prompt	What It Tests
Profitability	An auto insurer has seen its combined ratio rise from 95% to 108% over three years. How should it restore profitability?	Revenue vs. cost analysis, loss ratio decomposition, pricing strategy
Market Entry	A traditional P&C insurer is considering entering the cyber insurance market. Should they enter?	Market sizing, competitive landscape, capability assessment
Pricing	A health insurer needs to set premiums for a new individual plan in Texas. How should they price it?	Actuarial logic, cost estimation, competitive benchmarking, willingness to pay
M&A	A global insurer is considering acquiring a mid-size specialty insurer. Should they proceed?	Synergy analysis, valuation, integration risk, strategic fit
Operations	A large insurer's claims processing takes 45 days on average. How can they reduce it to under 15 days?	Process improvement, technology adoption, cost-benefit analysis
Growth Strategy	A life insurer is seeing flat premium growth. How should they grow?	Customer segmentation, distribution channels, product innovation

Profitability and market entry cases are the most common. In my experience coaching candidates, about half of all insurance cases involve a profitability problem tied to rising claims costs or unfavorable loss ratios.

How Should You Build a Framework for an Insurance Case?

The best frameworks are tailored to the specific case you receive, not memorized templates. That said, understanding the key categories that matter in insurance will help you build better frameworks faster. For a complete guide on how to create unique, tailored frameworks for any case, check out our case interview frameworks article.

What Framework Works Best for an Insurance Profitability Case?

When an insurance company is losing money, the issue almost always comes down to three areas. A strong framework for an insurance profitability case should cover these.

1. Underwriting performance: Start by examining the combined ratio. Break it into the loss ratio (claims divided by premiums) and the expense ratio (operating expenses divided by premiums). Ask whether claims frequency has increased, whether claims severity has gone up, or whether premiums are underpriced relative to risk.

2. Investment performance: Look at the insurer's investment portfolio. Have interest rates changed? Are returns declining? Has the asset allocation shifted? A 1% change in yield on billions of dollars of float can swing profitability significantly.

3. External market factors: Investigate whether the industry is in a soft market (excess capacity, falling premiums) or a hard market (tight capacity, rising premiums). Check for regulatory changes, catastrophe trends, or competitive pressure that may be squeezing margins.

What Framework Works Best for an Insurance Market Entry Case?

Market entry cases in insurance require you to evaluate four key areas.

1. Market attractiveness: How large is the market? What is the growth rate? What are the average combined ratios? A market with $50 billion in premiums growing at 15% per year (like cyber insurance) is far more attractive than a mature, saturated market growing at 2%.

2. Competitive landscape: How concentrated is the market? Are incumbents entrenched? Is there room for a new entrant? In insurance, switching costs for commercial clients can be high because of established broker relationships.

3. Capabilities and fit: Does the insurer have the underwriting expertise, distribution network, technology, and regulatory licenses needed to compete? Insurance is a heavily regulated industry. Entering a new state or country can require years of regulatory approval.

4. Financial impact: What are the upfront costs? How long until profitability? What is the expected return on equity? Insurance often requires substantial capital reserves, which must be factored into the entry cost.

What Framework Works Best for an Insurance Pricing Case?

Pricing cases in insurance are unique because the insurer is pricing a product before knowing the actual cost. The "cost" is future claims, which are uncertain. A strong framework should cover three areas.

1. Expected claims cost: Estimate the expected frequency of claims (how often they happen) multiplied by the expected severity (how much each claim costs). This is the actuarial foundation of insurance pricing.

2. Expense loading and profit margin: Add operating expenses (distribution, administration, technology) and a target profit margin on top of expected claims. In the U.S. P&C industry, the typical expense ratio is around 25% to 30% of premiums.

3. Competitive and regulatory constraints: Compare the resulting premium to competitor prices and any regulatory price caps. In many U.S. states, insurance regulators must approve rate changes before they take effect, which limits pricing flexibility.

What Insurance Concepts Do You Need to Know for Case Interviews?

You do not need to be an actuary to ace an insurance case. But knowing these terms will help you speak confidently and follow the interviewer's data. Here are the most important insurance concepts for case interviews.

Term	Plain-English Definition
Premium	The price a policyholder pays for insurance coverage, usually monthly or annually
Claim	A request by the policyholder for the insurer to pay for a covered loss
Underwriting	The process of evaluating risk and deciding whether to insure someone and at what price
Loss Ratio	Claims paid divided by premiums earned. A 70% loss ratio means $0.70 of every premium dollar goes to claims.
Expense Ratio	Operating expenses divided by premiums. Covers distribution, admin, and overhead costs.
Combined Ratio	Loss ratio plus expense ratio. Below 100% means underwriting profit. Above 100% means underwriting loss.
Float	The money insurers hold between collecting premiums and paying claims, which they invest for returns
Deductible	The amount the policyholder pays out of pocket before insurance kicks in
Reinsurance	Insurance that insurers buy to protect themselves against catastrophic losses
Actuary	A specialist who uses math and statistics to calculate risk and set premium prices
Hard Market	A period of rising premiums, tighter underwriting, and reduced capacity (good for insurer profits)
Soft Market	A period of falling premiums, relaxed underwriting, and excess capacity (bad for insurer profits)
Catastrophe (CAT) Loss	A large-scale loss event like a hurricane, wildfire, or earthquake that generates massive claims
Moral Hazard	The tendency for insured people to take more risks because they know they are covered
Adverse Selection	When higher-risk individuals are more likely to buy insurance, skewing the risk pool

If the interviewer uses a term you do not know, ask for a definition. Interviewers expect this for industry-specific cases and will not penalize you. It is far better to ask than to guess and structure your analysis around a misunderstanding.

How Do You Solve an Insurance Case Interview Step by Step?

Let's walk through a complete insurance case using the same seven-step approach that works for any consulting case. If you want a detailed breakdown of each step, our case interview tips article covers the general strategy in depth.

Example case prompt: "Our client is a mid-size auto insurer operating in Florida. Their combined ratio has increased from 94% to 112% over the past three years. They are losing money and need your help figuring out what is going wrong and what they should do about it."

Step 1: Understand the case and take notes. Write down the key facts. The client is a Florida auto insurer. The combined ratio went from 94% to 112%, meaning they went from a 6% underwriting profit to a 12% underwriting loss. The timeframe is three years.

Step 2: Ask clarifying questions. Good questions here would include: Is the combined ratio increase driven by the loss ratio, the expense ratio, or both? Does the client write policies in other states or just Florida? Has the client's premium volume changed over this period? These questions help you narrow the problem before building your framework.

Step 3: Structure a framework. Based on the problem, a strong framework might have three buckets. First, claims analysis: examine whether claim frequency or claim severity (or both) has increased. Second, pricing analysis: determine whether premiums have kept pace with rising costs. Third, external factors: investigate whether Florida-specific issues like hurricane exposure, litigation trends, or regulatory restrictions are driving the problem.

Step 4: Lead the analysis. Start with the highest-impact bucket. In this case, the interviewer might reveal that claim severity for bodily injury has increased 40% in three years due to rising medical costs and increased litigation. Claim frequency is roughly flat. This tells you the problem is on the loss ratio side, specifically severity-driven.

Step 5: Handle quantitative questions. The interviewer might ask you to calculate how much premiums would need to increase to restore the combined ratio to 98%. If current premiums are $500 million and the combined ratio is 112%, the insurer is paying $560 million in claims plus expenses. To reach a 98% combined ratio, they would need $560M / 0.98 = $571 million in premiums, which is a 14.2% premium increase.

Step 6: Answer qualitative questions. The interviewer might ask what risks come with a 14% rate increase. You might note that policyholders could switch to competitors, that Florida regulators might reject such a large increase, or that the company could lose market share in a price-sensitive segment. This is where knowing that insurance is regulated and that rate approvals are required becomes valuable.

Step 7: Deliver your recommendation. A strong recommendation might be: "I recommend the client pursue a three-part strategy. First, file for a targeted rate increase of 10% focused on the highest-risk segments. Second, tighten underwriting criteria to reduce exposure to high-severity claims. Third, invest in fraud detection and claims management technology to reduce per-claim costs. If these actions do not restore profitability within 18 months, the client should consider exiting underperforming Florida zip codes."

What Are Practice Insurance Case Interview Questions?

Use these practice prompts to prepare for insurance case interviews. For each case, practice structuring a framework, identifying the key analyses you would run, and delivering a recommendation. For more practice cases across all industries, visit our case interview examples page.

Case 1 (Profitability): A large homeowners insurance company has seen its combined ratio jump from 97% to 115% after two consecutive years of severe hurricane seasons. Their CEO wants to know whether they should raise prices, exit high-risk coastal markets, or invest more in reinsurance.

How to approach: Decompose the combined ratio into loss ratio and expense ratio. Investigate which geographies and policy types are driving the loss ratio increase. Compare the cost of reinsurance vs. the cost of market exit vs. the revenue impact of premium increases. Quantify each option.

Case 2 (Market Entry): A traditional property and casualty insurer is evaluating whether to enter the U.S. cyber insurance market, which grew 25% in 2025 and is projected to reach $22 billion by 2028. Should they enter? If so, how?

How to approach: Assess market attractiveness using size, growth rate, and profitability metrics. Evaluate the competitive landscape and barriers to entry. Assess the client's capabilities in cyber risk assessment, which differs significantly from traditional P&C underwriting. Consider whether to build, buy, or partner.

Case 3 (Pricing): A health insurer is launching a new individual health plan in Texas. They need to set a premium that is competitive, compliant with state regulations, and profitable. Expected medical claims cost is $4,800 per member per year. How should they price the plan?

How to approach: Start with the expected claims cost of $4,800. Layer on administrative expenses (typically 15% to 20% of premiums for individual health plans). Add a target profit margin. Compare the resulting premium to competitors and check against any regulatory constraints on medical loss ratios under the Affordable Care Act, which requires health insurers to spend at least 80% of premiums on medical claims.

Case 4 (M&A): A European reinsurer is considering acquiring a specialty insurer that focuses on marine and aviation insurance. The target has $2 billion in annual premiums and a 94% combined ratio. Should the reinsurer proceed with the acquisition?

How to approach: Evaluate the strategic rationale: does marine and aviation specialty insurance complement the acquirer's existing portfolio? Assess the target's underwriting quality and consistency of its combined ratio over time. Estimate potential synergies in distribution, technology, and reinsurance purchasing. Calculate whether the acquisition price offers an attractive return.

Case 5 (Operations): A large auto insurer processes claims in an average of 30 days. Their competitor has reduced average processing time to 7 days using AI-powered claims assessment. How should the client modernize its claims operation?

How to approach: Map the current claims process end to end. Identify the biggest bottlenecks. Evaluate technology solutions such as AI damage assessment, automated fraud detection, and straight-through processing for simple claims. Estimate the cost of implementation against the savings from faster processing and improved customer retention.

The best way to practice these cases is with a partner who can play the role of interviewer. If you do not have a partner available, our guide on how to practice case interviews by yourself gives you a step-by-step method for solo preparation.

What Tips Help You Ace an Insurance Case Interview?

These tips are specific to insurance cases and will help you stand out from candidates who treat insurance like any other industry.

1. Always ask about the combined ratio. In any insurance profitability case, the combined ratio is the first metric you should request. It immediately tells you whether the problem is on the claims side, the expense side, or both.

2. Remember both revenue streams. Many candidates forget about investment income. If the interviewer says the insurer is losing money, ask whether that includes investment income or is just the underwriting result. This shows you understand how insurers actually make money.

3. Think about regulation. Insurance is one of the most heavily regulated industries. Rate changes often require regulatory approval. Market exits may require giving policyholders advance notice. M&A deals need approval from insurance commissioners in every state where the target operates. Always consider regulatory constraints in your recommendation.

4. Separate frequency from severity. When claims costs are rising, the natural follow-up question is whether it is because more claims are being filed (frequency) or each claim is costing more (severity). The solutions are different for each. Higher frequency might suggest fraud or expanded coverage. Higher severity might point to inflation, litigation, or catastrophe events.

5. Know the underwriting cycle. The insurance industry moves in cycles. In a hard market, premiums are rising and capacity is tight, which is good for insurer profits. In a soft market, premiums fall and competition intensifies. According to industry analysts, U.S. commercial lines are entering a softer phase in 2026, with property rates down 8% to 10% for preferred risks.

6. Do not be afraid to ask for definitions. If the interviewer uses a term like "reinsurance treaty" or "loss development factor" that you do not know, ask. This is expected in an industry-specific case and will not count against you. What will count against you is pretending to understand and building your analysis on a wrong assumption.

7. Connect your recommendation to implementation risk. Insurance recommendations often have long lead times. A rate increase takes months to file and approve. An IT modernization takes years to implement. A market exit triggers policyholder notification requirements. Acknowledge these timelines in your recommendation to show practical business judgment.

Frequently Asked Questions

Are insurance case interviews different from regular case interviews?

The format is identical. You will still structure a framework, analyze data, and deliver a recommendation. The only difference is the industry context. Insurance cases use industry-specific metrics like the combined ratio, loss ratio, and underwriting cycle. If you know the basics of how insurance works, you can apply the same case interview techniques you use for any other industry.

Do I need to be an insurance expert to pass an insurance case interview?

No. The interviewer will explain any technical details you need to solve the case. That said, candidates who demonstrate familiarity with basic insurance concepts like premiums, claims, and the combined ratio tend to move through the case faster and make a stronger impression. Spending 30 to 60 minutes learning the terminology in this article is more than enough preparation.

Which consulting firms give the most insurance cases?

Oliver Wyman gives insurance cases more frequently than any other major firm because financial services and insurance are core practices. Deloitte, EY, and Accenture also have large insurance consulting teams and may give insurance-related cases. At McKinsey, BCG, and Bain, insurance cases are less common in generalist rounds but may appear if you are interviewing for their financial services practices.

How should I prepare for an insurance case interview in one week?

First, learn the core case interview methodology using a structured resource like a case interview course. Second, spend one to two hours reading this article to understand insurance industry basics, key metrics, and common case types. Third, practice three to five insurance cases using the practice prompts in this guide. That combination will cover both the general case skills and the industry-specific knowledge you need.

What is the combined ratio and why does it matter in insurance cases?

The combined ratio is the sum of the loss ratio and the expense ratio. It measures whether an insurer is making or losing money on its core underwriting business. A combined ratio below 100% means the insurer is earning an underwriting profit, while above 100% means an underwriting loss. For context, the average U.S. P&C combined ratio has hovered between 96% and 102% in recent years. In case interviews, the combined ratio is usually the starting point for any insurance profitability analysis.
