📖 How to Interpret Ratio Results
A ratio on its own is meaningless — it only becomes useful when you compare it with something.
- State the result — e.g. 'The GPM is 35%'
- Explain what it means — e.g. 'The business keeps 35 cents of every dollar after COGS'
- Compare it — with previous years, competitors, or industry benchmarks
- Draw a conclusion — is the result good, bad, improving or declining?
- Recommend action — what should the business do?
Follow the 5-step approach: Calculate → State → Explain → Compare → Recommend. This structure guarantees strong answers! 🎯

🔄 Types of Comparison
Trend analysis (over time)
Compare the same ratio across multiple years to spot trends — is performance improving or declining?
- Shows direction of change (getting better or worse)
- Helps identify problems early before they become critical
- Most useful with at least 3 years of data
Inter-firm comparison (against competitors)
Compare ratios with similar businesses in the same industry to see how the business performs relative to its peers.
- Reveals competitive strengths and weaknesses
- Must compare like with like (same industry, similar size)
- Different accounting policies can distort comparisons
A GPM of 20% might be excellent in supermarkets (thin margins) but poor in luxury fashion (high margins). Always consider the industry! 🏪

⚠️ Limitations of Ratio Analysis
Ratios are powerful tools but they have important limitations:
- Based on historical data — past performance doesn't guarantee future results
- Ratios are only as good as the accounts — if accounts are manipulated (window dressing), ratios are unreliable
- Non-financial factors are ignored — staff quality, brand strength, market trends
- Different accounting methods make inter-firm comparisons difficult
- External factors — economic conditions, new regulations, pandemics affect results
- Snapshot vs trend — one year's ratio may not reflect the bigger picture
In the exam, mentioning 2-3 limitations in your evaluation shows excellent critical thinking and pushes you into the top mark band! 💎
💬 Commenting on Ratio Changes
When a ratio changes from one year to the next, you need to explain why and what it means.
Example: GPM dropped from 45% to 38%.
'The GPM has fallen by 7 percentage points, suggesting that the cost of goods sold has increased relative to revenue. This could be due to rising raw material prices or a shift toward lower-margin products. The business should investigate supplier costs and consider renegotiating or finding alternative suppliers.'
- State the DIRECTION of change (increased, decreased, stable)
- State the MAGNITUDE (by how many percentage points or how much)
- Suggest POSSIBLE CAUSES (why it changed)
- Recommend ACTIONS (what the business should do)
