A finance case study is not a calculation exercise dressed up in business prose. It is a different beast. Where a typical finance assignment hands you cash flows and asks you to compute NPV, a case study hands you a company in a situation and asks: what should they do, and why? The numbers still matter — but they are evidence in service of a recommendation, not the answer themselves.
This guide takes you through the full structure of a finance case study assignment, shows you which strategic frameworks to use (and when), walks through a short worked scenario, and demonstrates how to convert analysis into the recommendation that wins marks. If you need the underlying calculation techniques — ratio analysis, NPV, WACC — those live in our dedicated guides; this post is about the case study format that puts them to work.
What a Finance Case Study Actually Requires
A case study assignment tests something different from a standard finance question. The brief usually presents a company, an industry, a decision point, and a body of supporting information — sometimes financial statements, sometimes market data, sometimes both. Your job is to read the situation, identify the real problem, analyse it through finance and business frameworks, and arrive at a defensible recommendation.
Strong case study work always demonstrates five things:
- Problem identification — Can you separate the stated problem from the underlying problem? Cases often present symptoms (falling margins) when the root issue is structural (over-reliance on one customer segment).
- Framework application — Can you choose the right strategic and financial framework for the question, and apply it specifically to this case rather than describing it generically?
- Evidence-based analysis — Are your claims supported by the data in the case (and your own calculations from it), rather than asserted from intuition?
- Decision quality — Does your recommendation follow logically from your analysis, and does it acknowledge risks and trade-offs?
- Professional presentation — Is the document structured as a piece of business writing — clear, signposted, scannable — rather than as a continuous academic essay?
Check the case study type first: Some briefs ask you to analyse a case (descriptive — "what happened and why"), some ask you to recommend (decision-focused — "what should the company do"), and some ask both. The structure differs between them. Identify which type before you start, because writing a descriptive answer to a decision brief is one of the most common ways students underperform on case studies.
The Structure — Section by Section
A finance case study assignment typically follows this five-part structure. Word counts are calibrated for a 3,000-word case study — scale proportionally to your own limit.
| Section | Purpose | Word Count (3,000w) |
|---|---|---|
| Executive Summary | One-page overview: the company, the problem, your key findings, and your top-line recommendation. Written last but placed first. | 200–250w |
| Situation Analysis | Briefly establish the company, industry and context. Use external frameworks (PESTLE, Porter's Five Forces) to ground the analysis. | 500–600w |
| Problem Identification | State the core problem the case is asking about — separating symptoms from underlying causes — and frame the specific questions your analysis will answer. | 200–300w |
| Financial Analysis | Apply finance techniques to the case data: ratio analysis, valuation, investment appraisal, capital structure. Quote your evidence from the case. | 800–1,000w |
| Recommendations & Conclusion | State your recommendation, justify it from the analysis, acknowledge risks, and outline implementation considerations. | 500–700w |
| References & Appendices | Full references and detailed calculations. Not included in word count. | Not counted |
Two structural features distinguish a strong case study from a weak one. First, the executive summary appears at the top but is written last — markers often read it first to gauge whether the rest of the document is worth a careful read, so this paragraph is doing more work than its length suggests. Second, the recommendations section gets disproportionate space — almost a quarter of the document — because that is where decision quality is assessed and where the marks concentrate.
The Frameworks You'll Actually Use
A finance case study lives at the intersection of finance and business strategy, so the frameworks are a mix of both. You will not use all of these in one assignment — picking the right two or three for the question is part of the skill.
| Framework | What It Analyses | When to Use It |
|---|---|---|
| PESTLE | Political, Economic, Social, Technological, Legal, Environmental external factors. | Establishing the macro context when the case spans multiple countries or a turbulent environment. |
| Porter's Five Forces | Competitive intensity through buyer power, supplier power, substitutes, new entrants, and rivalry. | Industry analysis — why the firm's margins look the way they do. |
| SWOT | Strengths, Weaknesses, Opportunities, Threats — internal and external in one frame. | Synthesising situation analysis before moving to recommendations. Risk: lazy SWOTs read as bullet-point cliché. |
| Value Chain | Where the firm creates value — primary and support activities. | Operational or cost-structure questions; useful when the case is about efficiency or competitive advantage. |
| Ratio Analysis | Profitability, liquidity, efficiency, gearing. | Almost every finance case. See our ratio analysis guide for the full method. |
| NPV / DCF Valuation | The value of an investment or business based on discounted future cash flows. | Investment, acquisition, or project-evaluation cases. See our NPV and IRR guide. |
The selection rule is simple: pick the frameworks that answer the question the brief is asking. A case about whether a firm should acquire a competitor needs valuation (DCF), Five Forces (industry attractiveness), and ratio analysis (target's health). A case about restructuring a struggling division needs SWOT, Value Chain, and ratio analysis. Markers penalise frameworks that are name-checked but not applied; they reward two or three frameworks used with depth.
A Worked Mini-Case: Helios Retail Plc
To show the format in action, here is a short illustrative case study scenario and how a strong response would handle it. The case is constructed for demonstration; the structure mirrors what you would write in a full 3,000-word assignment.
Scenario: Helios Retail Plc, a UK-listed mid-market clothing retailer, has seen revenue grow by 8% over the past two years while operating margin has fallen from 11% to 8%. Its quick ratio has dropped from 1.1 to 0.7, and inventory days have risen from 52 to 71. The CEO is considering a major investment in an automated distribution centre at an initial cost of £12m, projected to save £2.5m annually for ten years. The CFO is concerned about funding the investment given current liquidity. Should Helios proceed with the investment?
Situation analysis: Frame Helios's current position. Revenue growth masks margin erosion and a deteriorating liquidity profile — the rising inventory days suggest cash is increasingly trapped in stock. Use Porter's Five Forces briefly to position the industry pressure (high rivalry, low switching costs in mid-market clothing) that is forcing margin compression.
Problem identification: The stated problem is whether to invest in the distribution centre. The underlying problem is that the working capital cycle is lengthening and the firm's cash position is weakening — making any major investment a liquidity decision as much as an appraisal decision.
Financial analysis: Apply ratio analysis to confirm the deterioration (link directly to ratio guide for method). Apply NPV at the firm's cost of capital — at 10%, ten years of £2.5m savings discount to a present value of around £15.4m, against the £12m outlay, suggesting NPV of roughly £3.4m. Layer in sensitivity: what if savings are 20% lower than projected? What if the cost of capital rises to 12%? Each test the robustness of the recommendation.
Recommendation: Conditional acceptance. The investment is financially attractive in isolation (positive NPV, sensitivity-resilient at the central case), but the firm's current liquidity position makes the timing the real issue. Recommend deferring by 6–9 months while addressing inventory turnover, then proceeding — funded partly through asset-backed financing rather than free cash, to preserve working capital headroom. Acknowledge the trade-off: delaying the savings by 6–9 months reduces NPV by roughly 20–30% (because the saved cash flows arrive later and discount more heavily), but protecting liquidity is the higher-order constraint.
Notice what this response does. It does not just compute NPV and accept the project. It identifies that the case has two layers — an investment decision and a liquidity constraint — and the recommendation resolves both. That is the analytical move case studies reward. A First-class response makes the trade-off explicit and quantifies the cost of the recommended path; a 2:2 response either ignores the liquidity issue or refuses to recommend at all.

2:2 vs First: The Recommendation Section
Almost every finance case study ends with a recommendation. The gap between a 2:2 and a First lives there — same case, same numbers, very different analytical work.
"The NPV of the distribution centre investment is positive at the firm's cost of capital, so the project should be accepted. The company will save £2.5m per year and this will improve its profitability over time. The investment is therefore a good decision for Helios Retail Plc."
"Acceptance is recommended conditionally. The investment is financially attractive on a standalone basis — NPV is positive at the firm's cost of capital and remains so under reasonable downside sensitivity. However, the firm's deteriorating liquidity position (quick ratio of 0.7, inventory days at 71) makes immediate funding from internal cash imprudent. The recommendation is to defer the project by 6–9 months, address working capital first, and fund the deferred investment through asset-backed financing — preserving liquidity headroom at the cost of a roughly 20–30% reduction in NPV due to deferred savings.
Five Mistakes That Cost Students Marks
Treating the case study as a calculation exercise. Producing ratios and an NPV without business interpretation misses the point of the format — case studies test decision-making.Fix: For every calculation, write one line on what it means for the company's decision. The numbers are evidence, not the answer.
Name-checking frameworks without applying them. A SWOT or PESTLE listed as bullet points with no link to the case earns very little. Markers spot generic framework use immediately.Fix: Apply each framework specifically — name the political risk that matters to this firm, the supplier-power dynamic in this industry, the specific weakness this company has. Generic frameworks score generic marks.
Solving the stated problem rather than the underlying one. Case briefs often present symptoms; the high marks go to students who diagnose the real issue.Fix: After your situation analysis, ask "what is the case really about?" Is it about the investment decision, or about why the firm is in a position where the investment is hard to fund?
Recommendations not anchored to the analysis. Generic advice ("the firm should improve cost control") that could have been written without reading the case earns almost nothing.Fix: Every recommendation should reference a specific piece of evidence from your analysis — a ratio, an NPV result, a competitive dynamic. Trace the line from data to decision.
Writing as an academic essay, not a business document. Continuous prose with no signposting, no executive summary, and no clear recommendation section reads as the wrong format for a case study.Fix: Use headed sections, an executive summary, and a clear recommendations heading. The document should be scannable — a marker should be able to find your key findings without re-reading.
