What this dot point is asking

NESA wants you to know the seven syllabus-named financial ratios, calculate them from a given balance sheet and income statement, interpret each one, and understand the limitations of financial reports. Section II questions on this dot point routinely give you a small set of figures and ask for two or three ratios plus interpretation. The maths is simple; the marks are in the interpretation.

The answer

The seven syllabus ratios

Ratio	Formula	What it measures
Current ratio	Current assets / Current liabilities	Short-term liquidity
Debt to equity	Total liabilities / Total equity	Gearing/solvency
Gross profit ratio	Gross profit / Sales	Profitability after COGS
Net profit ratio	Net profit / Sales	Profitability after all costs
Return on equity	Net profit / Total equity	Return earned per dollar of owner capital
Expense ratio	Total expenses / Sales	Cost efficiency
Accounts receivable turnover	Sales / Average accounts receivable	Speed of customer collection

Liquidity

Current ratio.

\text{Current ratio} = \frac{\text{Current assets}}{\text{Current liabilities}}

Interpretation: a current ratio above 1.0 means current assets cover current liabilities. A healthy ratio for most industries is between 1.5 and 2.0. Below 1.0 signals potential liquidity stress unless the business is a fast-turnover retailer with negative working capital by design.

Example: Woolworths Group typically reports a current ratio around 0.7-0.8 - low by general benchmark but normal for a supermarket because inventory turns over so fast.

Gearing (solvency)

Debt to equity.

\text{Debt to equity} = \frac{\text{Total liabilities}}{\text{Total equity}}

Interpretation: a ratio above 1.0 means more debt than equity. Capital-intensive industries (utilities, infrastructure, REITs) routinely run debt to equity above 1.5; manufacturing and services typically run below 1.0; tech companies often have very low gearing.

Higher gearing amplifies returns in good times (positive financial leverage) but raises insolvency risk in bad times. The Virgin Australia FY20 collapse was partly a debt-to-equity story - high gearing into a sudden revenue collapse left no margin.

Profitability

Gross profit ratio.

\text{Gross profit ratio} = \frac{\text{Gross profit}}{\text{Sales}} = \frac{\text{Sales} - \text{COGS}}{\text{Sales}}

Interpretation: the proportion of every sales dollar left after direct cost of goods. Industry-specific: software businesses can run gross margins above 80 percent; supermarkets around 25-28 percent; mining around 50 percent.

Net profit ratio.

\text{Net profit ratio} = \frac{\text{Net profit}}{\text{Sales}}

Interpretation: the proportion of every sales dollar left after all expenses (including operating expenses, interest and tax). Woolworths reports a net margin of around 3 percent; Apple globally reports around 25 percent (a high-margin technology business).

Return on equity (ROE).

\text{ROE} = \frac{\text{Net profit}}{\text{Total equity}}

Interpretation: the return earned per dollar of owner capital. The ASX 200 long-term average is around 11-13 percent. ROE is the most-watched profitability ratio because it speaks directly to shareholder return.

Efficiency

Expense ratio.

\text{Expense ratio} = \frac{\text{Total expenses}}{\text{Sales}}

Interpretation: the proportion of revenue consumed by total expenses. A lower ratio means more revenue is converted to profit. Aldi's expense ratio is structurally lower than Coles's because of leaner store operations.

Accounts receivable turnover.

\text{Accounts receivable turnover} = \frac{\text{Credit sales}}{\text{Average accounts receivable}}

Interpretation: how many times per year accounts receivable are collected and replaced. A higher number means faster collection. For most B2B businesses on 30-day terms, turnover of 10-12 times per year is normal.

A related figure - days sales outstanding (DSO):

\text{DSO} = \frac{365}{\text{Accounts receivable turnover}}

A DSO of 45 days means it takes the business an average of 45 days to collect from credit customers.

Trend, comparative and industry analysis

Single-period ratios are limited. Three analytical perspectives matter.

Trend analysis. How the ratio has moved over the past three to five years. A current ratio declining from 2.0 to 1.0 over five years is a warning even if 1.0 is acceptable today.
Comparative analysis. Comparing against a peer or against the business's own past performance. Coles compared to Woolworths is a fair comparative; Coles compared to Aesop is not.
Industry benchmarks. Industry-specific averages from ABS, IBISWorld or industry associations. A 2 percent net margin is good for a supermarket and dire for a software company.

Limitations of financial reports

NESA explicitly tests the limitations of financial reports for ratio analysis.

Historical. Reports show what happened, not what will happen.
Accounting judgement. Depreciation methods, inventory valuation, intangible asset values, provisions all involve judgement. Two honest businesses can report different profits.
Window dressing. Period-end timing of transactions can flatter the reported position.
Inflation. Reports are in nominal dollars. Comparing a $1 million 1995 figure with a$ 1 million 2025 figure ignores inflation.
Non-financial drivers ignored. Brand strength, IP value, staff capability, customer loyalty, ESG and reputational risk are not on the balance sheet but matter to value.
Comparability. Different accounting policies between businesses make direct comparison hard.
Industry context required. Ratios only make sense against an industry benchmark.

Tying it together: a worked Australian comparison

Comparing Coles and Woolworths Group on illustrative FY24 figures.

Ratio	Coles FY24	Woolworths FY24	Interpretation
Current ratio	~0.68	~0.65	Both run low - structural for supermarkets
Debt to equity	~1.4	~1.6	Both moderately geared; Woolworths slightly higher
Gross profit ratio	~26%	~28%	Woolworths captures slightly more margin per sales dollar
Net profit ratio	~2.7%	~2.8%	Very similar; net margin is structurally thin in supermarkets
Return on equity	~30%	~28%	Both well above ASX average; high asset turnover drives ROE
Expense ratio	~22%	~24%	Coles slightly leaner cost base

The conclusion: both supermarkets run very similar financial profiles, reflecting near-duopoly dynamics. The small differences are within normal year-on-year noise. The story is in trends, not single-period levels.

Worked example

"Calculate and interpret the debt to equity ratio and the return on equity for a business with total liabilities $2,400,000, total equity$ 1,600,000, and net profit $240,000. (4 marks)"

Debt to equity.

\text{Debt to equity} = \frac{2{,}400{,}000}{1{,}600{,}000} = 1.50

Interpretation: the business has $1.50 of debt for every$ 1 of owner equity. This is a moderately high gearing - common in capital-intensive industries but risky for cyclical or service businesses. The business should be confident in stable cash flows to service the interest on this debt.

Return on equity.

\text{ROE} = \frac{240{,}000}{1{,}600{,}000} = 0.15 = 15\%

Interpretation: for every $1 of owner equity, the business generates 15 cents of net profit annually. This is above the long-term ASX 200 average of around 12 percent, suggesting strong returns for owners. The 1.5 gearing amplifies these returns; if business conditions deteriorate, the same gearing will amplify losses.

Together: the business is generating attractive returns but with significant leverage. The directors should consider whether the current gearing is sustainable through a downturn.

Past exam questions, worked

Real questions from past NESA papers on this dot point, with our answer explainer.

2023 HSC6 marksUsing the financial data provided, calculate the current ratio, gross profit ratio and return on equity. Briefly interpret each.

Show worked answer →

Assume given: current assets $800,000; current liabilities$ 500,000; sales $4,000,000; cost of goods sold$ 2,400,000; net profit $200,000; total equity$ 1,500,000.

Current ratio.

\text{Current ratio} = \frac{800{,}000}{500{,}000} = 1.60

Interpretation: the business holds $1.60 of current assets for every$ 1 of current liabilities. This is a healthy short-term liquidity position, comfortably above 1.0.

Gross profit ratio.

Gross profit = sales - COGS = 4,000,000 - 2,400,000 = 1,600,000.

\text{Gross profit ratio} = \frac{1{,}600{,}000}{4{,}000{,}000} = 0.40 = 40\%

Interpretation: for every $1 of sales, the business retains 40 cents after the direct cost of goods. Strong for a retail or services business; lower for a heavy-manufacturing business.

Return on equity (ROE).

\text{ROE} = \frac{200{,}000}{1{,}500{,}000} = 0.133 = 13.3\%

Interpretation: for every $1 of owner equity, the business generates 13.3 cents of net profit annually. Comparable to or slightly above an average ASX 200 ROE; depends on industry benchmark.

Markers reward (1) correct formula and calculation for each ratio, (2) interpretation linked to the number, (3) acknowledgement that judgement depends on industry benchmark and trend.
