Limitations of Ratio Analysis and Financial Decision Making WACE Accounting and Finance Unit 4
“Explain the limitations of ratio analysis, evaluate the role of non-financial and ethical factors in decision-making, and recommend a course of action using both financial and qualitative information”
Ratios are useful but limited. They use historical data, depend on the quality of the underlying reports, ignore non-financial factors, and can be distorted by different accounting policies or one-off events. A sound decision combines ratio analysis with non-financial information (staff, reputation, market conditions) and with ethical considerations (the effect on employees, customers, the community and the environment). The best recommendation weighs the financial evidence alongside these qualitative factors.

What this dot point is asking
SCSA wants you to explain why ratios can mislead, evaluate non-financial and ethical factors, and reach a justified recommendation using both.
Limitations of ratio analysis
Ratios are based on historical financial statements, so they describe the past rather than guarantee the future. They are only as reliable as the reports behind them, and they can be distorted when businesses use different accounting policies, making comparisons unfair. A single ratio in isolation says little; it needs a benchmark such as prior years or industry averages. One-off events, seasonal timing and inflation can all skew a ratio, and ratios capture nothing about quality, staff morale or market position.
Because of these limits, ratios are best used as a group, compared over time and against similar businesses, and read alongside the notes to the accounts.
Non-financial factors
A decision based only on numbers can be poor. Non-financial factors include the skill and morale of staff, the strength of the brand and customer loyalty, the state of the economy and competition, the quality of management, and legal or regulatory changes. These can outweigh a favourable set of ratios, or rescue an investment that looks weak on paper.
Ethical factors
Ethical decision-making considers the effect of a choice on all stakeholders, not just on profit. It weighs the interests of employees, customers, suppliers, the community and the environment, and considers honesty and fairness in how the business reports and behaves. An ethical lens can change a decision that the financial figures alone would support.
A decision that maximises short-term profit might damage the environment, mistreat workers or mislead customers, harming the business's reputation and long-term value. Ethical and financial considerations therefore often point in the same direction over the long run.
Building a justified recommendation
The hardest marks in this dot point come from turning analysis into a defensible recommendation. A strong answer follows a clear shape. First, state what the ratios show, in plain terms (for example, profitability has fallen and is below the benchmark). Second, qualify that evidence by naming the relevant limitations: is the figure distorted by a one-off cost, an unusual accounting policy, or a seasonal timing effect? Third, bring in the non-financial factors that the numbers cannot capture, such as staff capability, brand strength, market conditions and the quality of management. Fourth, weigh the ethical dimension: who is affected by the decision, and how. Finally, recommend a course of action and justify it by reference to all of the above, ideally with a review trigger (for example, monitor next year once the one-off cost drops out). The examiner is testing judgement, not arithmetic: the ratios are evidence to be interpreted and weighed, never a verdict to be applied mechanically.
A company is deciding whether to close a regional store. The store's net profit margin is 3 per cent against the company average of 9 per cent, and its return on assets is well below target, so the ratios favour closure. Before deciding, management considers the limitations and the wider factors.
The ratios are historical and partly reflect a one-off refurbishment cost this year, which overstated expenses; adjusting for it lifts the margin to 6 per cent. Non-financial factors include a loyal local customer base and the store's role in brand presence in the region. Ethical factors include the loss of 12 local jobs and the effect on the community.
Weighing all of this, a reasonable recommendation is to keep the store open for now, monitor its performance once the one-off cost drops out, and set a clear profitability target for review next year. The decision uses the ratios as evidence but is not dictated by them alone.
Students often calculate ratios and then recommend a decision purely from the numbers. Ratios are evidence, not a verdict. A strong answer states what the ratios show, acknowledges their limitations, and then weighs relevant non-financial and ethical factors before recommending and justifying a course of action.
Exam-style questions
Questions in the style of SCSA exam questions on this dot point, each with a worked answer. They are written by ExamExplained unless tagged "Past paper"; the year shows the paper a question is modelled on.
WACE 2022-style7 marksA business is deciding whether to close a branch whose net profit margin is 4 per cent against a company average of 10 per cent. Explain three limitations of relying on this ratio alone, and identify two non-financial and one ethical factor that should inform the decision.Show worked answer →
A 7 mark response needs three limitations plus the named factors.
Limitations. First, the ratio is historical, describing the past rather than guaranteeing the future. Second, it may be distorted by one-off events (for example a refurbishment cost this year) that overstate expenses and understate the margin. Third, a single ratio in isolation needs a benchmark and context; different accounting policies can also make the comparison with the company average unfair.
Non-financial factors. The loyalty of the local customer base and the branch's role in maintaining brand presence and market share in that region.
Ethical factor. The effect on employees who would lose their jobs, and the wider impact on the local community. A sound recommendation weighs the ratio as evidence alongside these factors rather than deciding on the number alone. Markers reward three genuine limitations and correctly classified non-financial and ethical factors.
WACE 2023-style5 marksExplain why a decision that maximises short-term profit may not be in a business's long-term interest, using one ethical and one non-financial consideration.Show worked answer →
A 5 mark response needs the argument with both considerations applied.
Ethical consideration. Cutting costs by mistreating workers, misleading customers or damaging the environment may lift this year's profit but can breach the trust of stakeholders, attract penalties, and harm the business's reputation, reducing long-term value.
Non-financial consideration. Eroding product quality or customer service to save cost can lift short-term margins while driving away loyal customers and weakening the brand, lowering future sales. Because reputation and customer loyalty drive long-run profitability, ethical and financial interests usually align over time, so a purely short-term, profit-maximising choice can destroy more value than it creates. Markers reward a clear short-term-versus-long-term argument with one ethical and one non-financial point.
