Ratio Analysis and Business Performance WACE Year 12 Accounting and Finance
“Calculate and interpret profitability, liquidity, efficiency and financial stability ratios, and evaluate business performance and its limitations using ratio analysis”
Ratios convert raw financial statement figures into comparable measures. Profitability ratios (such as gross profit margin and return on equity) show how well a business generates profit. Liquidity ratios (such as the current ratio) show short-term ability to pay debts. Efficiency ratios (such as inventory turnover) show how well assets are used. Stability ratios (such as the debt ratio) show long-term solvency. Always interpret, not just calculate.

What this dot point is asking
SCSA wants you to calculate ratios from company statements, interpret what each says about performance, compare across periods or against benchmarks, and discuss the limitations of ratio analysis.
Profitability ratios
Gross profit margin = Gross profit / Net sales x 100
Net profit margin = Profit / Net sales x 100
Return on equity = Profit / Average equity x 100
A rising gross profit margin suggests better pricing or lower cost of sales. Return on equity measures the return generated for shareholders on their funds.
Liquidity ratios
Current ratio = Current assets / Current liabilities
A current ratio of 2 to 1 means $2 of current assets back every $1 of current liabilities. Too low signals difficulty paying short-term debts; very high may signal idle assets.
Efficiency ratios
Inventory turnover measures how many times a business sells and replaces its average inventory in a period. It equals Cost of Sales divided by average inventory. A higher figure usually means faster-moving stock and less cash tied up.
The accounts receivable turnover (or collection period) shows how quickly the business converts credit sales into cash.
Financial stability ratios
Debt ratio = Total liabilities / Total assets x 100
Equity ratio = Total equity / Total assets x 100
A high debt ratio means heavy reliance on borrowed funds, raising financial risk because interest must be paid regardless of profit.
Interpreting ratios
Ratios are only meaningful in context. Compare them over time (trend analysis) and against industry benchmarks or competitors. A single number in isolation tells you little.
The four families of ratios are most powerful when read together, because they can tell a connected story or expose a contradiction. A high current ratio looks like strong liquidity, but if inventory turnover is falling at the same time, the liquidity may be an illusion created by slow-moving stock rather than genuine ability to pay. A rising return on equity is good news, but if it is driven by heavy gearing rather than better trading, the extra return comes with extra risk. A widening gap between gross profit margin and net profit margin points to operating expenses rather than cost of sales as the pressure point. Reading profitability, liquidity, efficiency and stability ratios as a set, and against both prior years and industry benchmarks, is what turns calculation into genuine analysis of business performance.
Coastline Ltd reports current assets of $180 000 and current liabilities of $90 000, so its current ratio is:
Net sales are $600 000 and gross profit is $240 000, giving a gross profit margin of:
Last year the margin was 45 per cent, so profitability has slipped even though liquidity of 2 to 1 looks healthy. The combined story is a business that can pay its short-term debts but is earning less on each sales dollar, prompting questions about pricing or rising supplier costs.
Who uses ratios, and for what
Different users read the same ratios for different purposes, and tailoring interpretation to the user strengthens an answer. Owners and shareholders focus on profitability and returns, especially return on equity, to judge whether their investment is performing. Lenders and prospective creditors focus on liquidity and gearing, to judge whether the business can service and repay debt. Managers use the full set, including efficiency ratios, to identify where performance is slipping and where to act. Prospective investors and analysts combine ratios with trends and benchmarks to value the business. Because each user weighs the families differently, a question that names a user (a bank considering a loan, an investor deciding whether to buy shares) is signalling which ratios to emphasise. Recognising the user and directing the interpretation toward their decision is what lifts a calculation into genuine analysis.
A frequent error is to compute a ratio and stop. Marks come from interpretation: state whether the result is favourable or unfavourable, compare it with the prior year or a benchmark, and explain a likely cause. Remember ratios use historical data, can be distorted by different accounting policies, and ignore non-financial factors like staff quality.
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-style8 marksTwo years of data for Halse Ltd: gross profit margin fell from 44 per cent to 38 per cent; net profit margin fell from 12 per cent to 7 per cent; current ratio rose from 1.8 to 2.4; inventory turnover fell from 8 to 5 times. Interpret what these trends suggest about the company's performance and identify a likely concern.Show worked answer →
An 8 mark response needs interpretation of each trend and a linked concern.
Gross profit margin. A fall from 44 to 38 per cent means less profit per sales dollar before operating costs, suggesting rising cost of sales or price cutting.
Net profit margin. A larger fall from 12 to 7 per cent means operating expenses are also eating into profit, so the problem is both gross margin and cost control.
Current ratio. A rise from 1.8 to 2.4 looks like stronger liquidity, but read with the next ratio it may be the wrong kind.
Inventory turnover. A fall from 8 to 5 times means stock is moving more slowly. Likely concern. The rising current ratio is partly driven by a build-up of slow-moving inventory, tying up cash and risking obsolescence rather than genuine liquidity strength. The overall picture is deteriorating profitability with stock management issues. Markers reward interpreting each trend (not just restating it) and connecting the high current ratio to slow inventory.
WACE 2023-style5 marksExplain why a single ratio is of limited use on its own, and describe two ways an analyst can give a ratio meaningful context.Show worked answer →
A 5 mark response needs the limitation and two contextualising methods.
Limitation. A ratio is just a number; it carries no meaning until it is compared with something. On its own it cannot say whether performance is good, bad, improving or declining, and it ignores non-financial factors and the quality of the underlying reports.
Context. First, trend analysis: compare the ratio with the same ratio in prior years to see the direction of change. Second, benchmarking: compare it against industry averages or a close competitor to judge relative performance. A third method is comparing related ratios together (for example liquidity with inventory turnover) to test whether a result is genuinely favourable. Markers reward the in-isolation limitation and at least two valid context methods such as trend and benchmark comparison.
