Ratio analysis and interpretation

This chapter turns the financial statements into judgements about performance. It covers the four families of ratios - profitability, liquidity, efficiency and gearing - showing how each is calculated and, more importantly, interpreted, and it stresses that a ratio is only meaningful in comparison and subject to real limitations. Throughout, one consistent set of figures is used so the ratios can be seen as a coherent picture.

Ratio analysis and interpretation

Profitability ratios#

StandardAQA 7127 3.8

Profit margins

Fig. 1Working down the income statement: the gross margin (40%) falls to the operating margin (15%) as overheads bite, and to the net margin (9.4%) after interest and tax.

Profitability ratios express profit relative to sales or to the capital invested, so that performance can be compared across firms of different sizes and across years. The three margin ratios work down the income statement. The gross profit margin is gross profit as a percentage of revenue; it shows how much of each pound of sales is left after the direct cost of the goods, and it reflects pricing and the control of direct costs. The operating profit margin is profit from operations as a percentage of revenue; it captures the profitability of the core trading after overheads but before interest and tax. The profit-for-the-year margin (net margin) is the profit for the year as a percentage of revenue - the bottom line after interest and tax.

Comparing the margins is revealing. Using the illustrative figures - revenue £800,000, gross profit £320,000, operating profit £120,000 and profit for the year £75,000 - the gross margin is 40%, the operating margin is 15% and the net margin is about 9.4%. The fall from 40% to 15% shows that overheads (distribution and administrative expenses) absorb a large slice of the gross profit, which would be worth investigating; the further fall to 9.4% reflects the finance costs and tax. A related measure, the mark-up, expresses gross profit as a percentage of cost of sales rather than revenue - here £320,000 / £480,000 = about 66.7% - and is useful when a business sets prices by adding a percentage to cost.

The primary profitability ratio is the return on capital employed (ROCE), because it relates profit to the capital used to earn it. It is calculated as operating profit divided by capital employed, expressed as a percentage, where capital employed is the long-term capital in the business - equity plus non-current liabilities, or equivalently total assets less current liabilities. With operating profit of £120,000 and capital employed of £560,000, ROCE is about 21.4%, meaning the business earns roughly 21 pence of operating profit for every pound of long-term capital. ROCE is best judged against the firm's own past ROCE, against competitors, and against the cost of that capital: a ROCE below the interest rate on borrowing is a serious warning sign.

Interpreting profitability well means going beyond the number to its causes and its context. A margin is 'good' only relative to the firm's strategy and industry: a cost-leader typically runs low margins on high volume, a differentiator higher margins on lower volume. A falling gross margin points to price competition or rising input costs; a gross margin that holds while the operating margin falls points to overheads growing faster than sales. ROCE can be improved either by raising the operating margin or by using capital more intensively (higher asset turnover), and separating the two tells a manager where to act. The discipline throughout is calculate, then interpret, then compare - never quote a ratio in isolation.

\text{Gross profit margin} = \frac{\text{Gross profit}}{\text{Revenue}} \times 100\%

Gross profit margin

Reflects pricing and direct-cost control. Here 320,000 / 800,000 = 40%.

\text{Operating profit margin} = \frac{\text{Operating profit}}{\text{Revenue}} \times 100\%

Operating profit margin

Core trading profitability after overheads, before interest and tax. Here 120,000 / 800,000 = 15%.

ROCE = \frac{\text{Operating profit}}{\text{Capital employed}} \times 100\%

Return on capital employed

The primary profitability ratio. Capital employed = equity + non-current liabilities. Here 120,000 / 560,000 = 21.4%.

Worked example

Calculating and interpreting profitability

A company reports revenue £800,000, cost of sales £480,000, operating profit £120,000, profit for the year £75,000 and capital employed £560,000. Calculate the gross, operating and net margins, the mark-up and ROCE, and interpret them.

Margins
Gross profit = £800,000 - £480,000 = £320,000. Gross margin = 320,000 / 800,000 = 40%. Operating margin = 120,000 / 800,000 = 15%. Net margin = 75,000 / 800,000 = 9.4% (to 1 dp).
Mark-up and ROCE
Mark-up = 320,000 / 480,000 = 66.7%. ROCE = operating profit / capital employed = 120,000 / 560,000 = 21.4%.
Interpret
The 40% gross margin falls to 15% operating, so overheads absorb a large share and merit investigation. A 21.4% ROCE is healthy if it exceeds the cost of capital and rivals' returns, but these figures are only meaningful compared with prior years and competitors.

Result: Gross margin 40%, operating margin 15%, net margin 9.4%, mark-up 66.7% and ROCE 21.4% - profitable, with overheads taking a notable share; the judgement depends on comparison with the past, rivals and the cost of capital.

Typical mistakes

Using the wrong profit in each ratio (for example net profit instead of operating profit in ROCE).
Dividing by cost of sales instead of revenue for a margin, or quoting a ratio without any comparison.

Liquidity ratios#

StandardAQA 7127 3.8

Current and acid-test ratios

Fig. 2The acid-test ratio (1:1) strips out inventory from the current ratio (1.67:1); the gap shows how much of the firm's short-term cover depends on selling inventory.

Liquidity ratios measure a business's ability to meet its short-term obligations - its capacity to pay its debts as they fall due - and they matter because a business can be profitable yet fail for want of cash. The current ratio compares current assets with current liabilities: current assets divided by current liabilities, usually expressed as a ratio to one. It shows how many pounds of short-term assets are available for each pound of short-term debt. Using the illustrative figures - current assets £150,000 and current liabilities £90,000 - the current ratio is £150,000 / £90,000 = 1.67:1, meaning the firm has £1.67 of current assets for every £1 of current liabilities.

The acid-test ratio (also called the quick or liquid ratio) is a sterner test, because it excludes inventory from current assets on the ground that inventory is the least liquid current asset - it must first be sold, and then the receivable collected, before it becomes cash. It is calculated as current assets less inventory, divided by current liabilities. With inventory of £60,000, the acid-test ratio is (£150,000 - £60,000) / £90,000 = £90,000 / £90,000 = 1:1, meaning the firm's liquid assets exactly cover its current liabilities. The acid test is the better guide to immediate liquidity for a business that cannot quickly turn inventory into cash.

Interpreting these ratios requires judgement rather than a fixed ideal. Textbooks once quoted 2:1 for the current ratio and 1:1 for the acid test as 'ideal', but the appropriate level depends heavily on the industry and the business model. A supermarket holds fast-moving inventory, sells for cash and pays suppliers on credit, so it operates comfortably with a current ratio well below 1 and an acid test far below 1 - and this is a strength, not a weakness, of its model. A manufacturer with slow-moving inventory and credit customers needs higher ratios. So a ratio must be read against the norms of the sector and the firm's own trend, not against a universal benchmark.

Both too little and too much liquidity are problems, which is the key evaluative point. Too little liquidity risks the firm being unable to pay its debts - a liquidity crisis that can force even a profitable business into insolvency. But too much liquidity is inefficient: cash sitting idle, excessive inventory, or overgenerous credit to customers all tie up resources that could be earning a return, so a very high current ratio can signal poor working-capital management rather than strength. The best position is enough liquidity to be safe without so much that resources are wasted, and interpreting the ratios means asking whether the firm is comfortably solvent, dangerously tight, or carrying idle resources.

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

Current ratio

Short-term assets per pound of short-term debt. Here 150,000 / 90,000 = 1.67:1.

\text{Acid-test ratio} = \frac{\text{Current assets} - \text{Inventory}}{\text{Current liabilities}}

Acid-test (quick) ratio

Excludes inventory as the least liquid asset. Here (150,000 - 60,000) / 90,000 = 1:1.

Worked example

Calculating and interpreting liquidity

A firm has current assets of £150,000 (of which inventory is £60,000) and current liabilities of £90,000. Calculate the current and acid-test ratios and comment.

Current ratio
Current assets / current liabilities = £150,000 / £90,000 = 1.67:1 - £1.67 of current assets per £1 of current liabilities.
Acid-test ratio
(Current assets - inventory) / current liabilities = (£150,000 - £60,000) / £90,000 = £90,000 / £90,000 = 1:1.
Comment
The current ratio of 1.67:1 looks comfortable, and the acid test of 1:1 shows liquid assets exactly cover current liabilities - reasonable, but with no cushion once inventory is stripped out. Whether this is adequate depends on the industry and the firm's own trend.

Result: Current ratio 1.67:1 and acid-test ratio 1:1 - the firm appears able to meet its short-term debts, though the acid test shows little margin once inventory is excluded; the judgement depends on the sector norm and the trend.

Typical mistakes

Quoting fixed 'ideal' ratios (2:1, 1:1) without reference to the industry or business model.
Forgetting to exclude inventory from the acid-test ratio.

Efficiency (activity) ratios#

StandardAQA 7127 3.8

The working-capital cycle

Fig. 3The working-capital cycle: inventory days (46) plus receivables days (37) less payables days (68) gives a short 15-day cash cycle, favourable for liquidity.

Efficiency (or activity) ratios measure how well a business manages its working capital and its assets - how quickly it turns inventory into sales, collects from customers, pays suppliers, and uses its non-current assets. They give the detail behind the liquidity ratios, because liquidity depends not just on the level of current assets but on how fast they cycle into cash. The inventory turnover measures how many times a year the business sells and replaces its inventory: cost of sales divided by (average) inventory. With cost of sales £480,000 and inventory £60,000, inventory turnover is 8 times a year, which can also be expressed as inventory days - inventory / cost of sales x 365 = about 46 days - the average time an item sits in stock.

The trade receivables collection period measures how long, on average, credit customers take to pay: trade receivables / credit sales x 365. With receivables of £80,000 and revenue of £800,000, this is about 37 days. The trade payables payment period measures how long the business itself takes to pay its suppliers: trade payables / credit purchases (or cost of sales) x 365; with payables of £90,000 and cost of sales £480,000, about 68 days. Comparing the two is informative: here the firm pays its suppliers (68 days) more slowly than it collects from customers (37 days), which eases cash flow because it is, in effect, being financed by its suppliers.

These ratios together describe the working-capital (cash operating) cycle - the time between paying for inventory and collecting the cash from selling it: inventory days plus receivables days minus payables days. Here that is 46 + 37 - 68 = 15 days, a short cycle that is favourable for cash flow. A lengthening cycle ties up more cash and can strain liquidity, so managers watch these ratios closely and act on them - chasing overdue receivables, reducing slow-moving inventory, or negotiating longer supplier credit. The non-current asset turnover (revenue / non-current assets; here £800,000 / £500,000 = 1.6 times) measures how intensively the long-term assets are used to generate sales, and links back to ROCE.

Interpreting efficiency ratios means reading them in the round and against context. A very fast inventory turnover may show tight stock control, or it may show stockouts and lost sales; a long collection period may show poor credit control, or a deliberate policy of generous credit to win customers; slow payment to suppliers eases cash flow but risks losing discounts, goodwill or supply. So each ratio invites a question rather than delivering a verdict, and the analyst must consider the trade-offs and the firm's strategy. Efficiency ratios are especially powerful in combination and over time, because a deteriorating trend in the cash cycle is an early warning that the liquidity ratios may worsen next.

\text{Inventory turnover} = \frac{\text{Cost of sales}}{\text{Inventory}}

Inventory turnover

Times per year inventory is sold and replaced. As days: inventory / cost of sales x 365.

\text{Receivables days} = \frac{\text{Trade receivables}}{\text{Credit sales}} \times 365

Collection period

Average days credit customers take to pay. Compare with the credit terms offered.

\text{Payables days} = \frac{\text{Trade payables}}{\text{Credit purchases}} \times 365

Payment period

Average days the firm takes to pay suppliers. Cost of sales is often used where purchases are not given.

Worked example

The working-capital cycle

From cost of sales £480,000, inventory £60,000, revenue £800,000, trade receivables £80,000 and trade payables £90,000, calculate the inventory, receivables and payables days and the length of the cash cycle.

Inventory and receivables days
Inventory days = 60,000 / 480,000 x 365 = 45.6, so about 46 days. Receivables days = 80,000 / 800,000 x 365 = 36.5, so about 37 days.
Payables days
Payables days = 90,000 / 480,000 x 365 = 68.4, so about 68 days - the firm takes about 68 days to pay suppliers.
Cash cycle and comment
Cash cycle = inventory days + receivables days - payables days = 46 + 37 - 68 = 15 days. A short cycle that is favourable for cash flow, because suppliers are, in effect, financing much of the firm's inventory and receivables.

Result: Inventory 46 days, receivables 37 days, payables 68 days, giving a 15-day cash cycle - the firm collects from customers and pays suppliers in a way that funds much of its working capital, easing liquidity.

Typical mistakes

Mixing up the numerator and denominator - inventory days uses cost of sales, receivables days uses revenue.
Reading a fast turnover or a long collection period as automatically good or bad, ignoring the trade-offs.

Active revision

Cost of sales £480,000, inventory £60,000, revenue £800,000, receivables £80,000 and payables £90,000. Calculate the inventory, receivables and payables days and the cash cycle, and comment.

Gearing#

AdvancedAQA 7127 3.8

Capital structure and gearing

Fig. 4The capital structure: equity £310,000 and long-term debt £250,000 give gearing of about 44.6% (debt as a share of the £560,000 capital employed).

Gearing measures the extent to which a business is financed by debt (borrowing) rather than by equity (owners' funds), and so measures financial risk. The gearing ratio is commonly calculated as non-current liabilities (long-term debt) divided by capital employed, expressed as a percentage - here, with non-current debt of £250,000 and capital employed of £560,000, gearing is about 44.6%. An equivalent measure is debt divided by equity. A highly geared business (broadly, gearing above about 50%) relies heavily on debt; a low-geared business relies mainly on equity. Because debt carries obligatory interest and repayment, gearing is the single clearest indicator of the financial risk in a firm's capital structure.

High gearing is a double-edged sword. In good times, borrowing at a fixed interest rate to earn a higher return magnifies the return to the ordinary shareholders - the firm earns more on the borrowed money than it pays in interest, and the surplus accrues to the owners. But in bad times the effect reverses brutally: the fixed interest must still be paid even as profits fall, so a downturn hits the shareholders' return much harder in a highly geared firm, and if profits fall below the interest bill the firm makes a loss and may be unable to meet its commitments. Gearing therefore amplifies both the upside and the downside - it raises expected return but also risk.

The interest cover ratio complements gearing by measuring how comfortably the firm can pay its interest out of profit: operating profit divided by finance costs. With operating profit of £120,000 and finance costs of £20,000, interest cover is 6 times - the firm earns six times the interest it must pay, a comfortable margin. A low interest cover (say below about 2 or 3 times) is a warning that even a modest fall in profit could leave the firm unable to meet its interest, so lenders watch it closely. Gearing shows how much debt there is; interest cover shows whether the firm can service it - the two together give a rounded view of financial risk.

Interpreting gearing requires judgement about the firm's circumstances. A business with stable, predictable profits (a utility, say) can safely carry higher gearing because it can rely on covering the interest; a business with volatile profits should be more cautious, because a bad year could be dangerous. Lenders resist lending to already highly geared firms (raising the cost or refusing credit), and shareholders may welcome moderate gearing for the boost to returns but fear excessive gearing for the risk. So a 'good' level of gearing depends on the stability of profits, the industry, interest rates and attitudes to risk - and, as always, the ratio is best read against the firm's own trend and its competitors rather than an absolute rule.

\text{Gearing} = \frac{\text{Non-current liabilities}}{\text{Capital employed}} \times 100\%

Gearing ratio

Debt as a share of long-term capital. Here 250,000 / 560,000 = 44.6%. Above about 50% is considered highly geared.

\text{Interest cover} = \frac{\text{Operating profit}}{\text{Finance costs}}

Interest cover

How many times profit covers the interest. Here 120,000 / 20,000 = 6 times - a comfortable margin.

Worked example

Assessing gearing and interest cover

A company has long-term debt of £250,000, equity of £310,000, operating profit of £120,000 and finance costs of £20,000. Calculate the gearing ratio and interest cover and assess the financial risk.

Gearing ratio
Capital employed = equity £310,000 + debt £250,000 = £560,000. Gearing = 250,000 / 560,000 = 44.6% - moderately geared, below the 50% high-gearing threshold.
Interest cover
Interest cover = operating profit / finance costs = 120,000 / 20,000 = 6 times - the firm earns six times its interest bill.
Assess
Gearing of 44.6% is moderate and interest cover of 6 times is comfortable, so the financial risk looks acceptable. The firm could probably service more debt, but whether it should depends on the stability of its profits: if profits are volatile, the fixed interest could become dangerous in a downturn.

Result: Gearing of 44.6% and interest cover of 6 times indicate moderate, well-covered borrowing and acceptable financial risk - a position that is safer the more stable the firm's profits.

Typical mistakes

Confusing gearing (a financing/risk ratio) with liquidity (a short-term solvency ratio).
Declaring high gearing always bad - it can boost returns and is safer for firms with stable profits.

Interpreting ratios and their limitations#

AdvancedAQA 7127 3.8

Families of ratios

Fig. 5The five families of ratios, each answering a different question - a rounded judgement reads them together and always in comparison.

Ratios come in families that answer different questions, and interpretation means reading them together to build a coherent picture. Profitability ratios ask whether the business is making enough profit; liquidity ratios whether it can pay its debts; efficiency ratios how well it manages its assets and working capital; gearing how risky its financing is; and, for companies, investment ratios (such as earnings per share and dividend yield) how the shares reward their holders. A rounded judgement weaves these together - a firm can be highly profitable yet illiquid, or liquid yet over-borrowed - so the analyst looks for the story the ratios tell as a set, and for the interactions between them (a lengthening cash cycle threatening liquidity, high gearing amplifying a profit fall).

A ratio is only meaningful in comparison, and this is the first rule of interpretation. A single ratio in isolation says almost nothing; it becomes informative only when compared - with the firm's own past figures (to reveal a trend), with competitors or the industry average (to reveal relative standing), or with a budget or target (to reveal whether plans are being met). A gross margin of 40% is neither good nor bad until you know whether it was 45% last year, or whether rivals earn 35% or 50%. Every interpretive answer should therefore reach for a comparison, and a conclusion drawn from one year's ratios with nothing to compare them against is worth little.

The limitations of ratio analysis are a rich and frequently-examined source of evaluation. Ratios are based on the published financial statements, which are historic (often months out of date by the time they are read), are prepared on the historical-cost basis (so they can be distorted by inflation and understate current values), and reflect accounting policy choices (a firm using a different depreciation method or inventory valuation is not strictly comparable). They can be distorted by one-off or seasonal events, and by 'window dressing' - arranging transactions around the year end to flatter the figures. And they are only as reliable as the accounts they come from, which returns us to the importance of honest, faithfully-represented information.

Above all, ratios ignore the non-financial factors that often determine a firm's future - the quality and morale of its staff, the strength of its brand and customer loyalty, the state of its markets and the economy, the calibre of its management, and its social and environmental standing - none of which appear in the accounts (recall the money-measurement concept). So ratio analysis is a powerful starting point that raises the right questions, but it does not answer them on its own: it must be combined with qualitative judgement and wider information. The skilled interpreter uses ratios to locate where to look, then investigates the causes, weighs the non-financial context, and reaches a reasoned conclusion - which is exactly the analysis-and-communication skill developed in the later synoptic chapter.

Ratio summary

Fig. 6The full ratio set for the illustrative company - a coherent picture: profitable (ROCE 21.4%), adequately liquid (acid test 1:1), efficient (15-day cash cycle) and moderately geared (44.6%).

Worked example

A rounded interpretation and its limits

A company shows ROCE 21.4%, gross margin 40%, current ratio 1.67:1, acid test 1:1, cash cycle 15 days and gearing 44.6%. Assess its overall position and state the limitations of relying on these ratios.

Read the families together
Profitability is healthy (ROCE 21.4%, gross margin 40%); liquidity is adequate (acid test exactly 1:1); efficiency is good (a short 15-day cash cycle); and gearing is moderate (44.6%) with interest well covered. The picture is of a sound, profitable, reasonably financed business.
Insist on comparison
This judgement is provisional until the ratios are compared with prior years and competitors: the same figures could be an improvement or a decline, above or below the industry - only comparison reveals which.
State the limitations
The ratios are historic and on the historical-cost basis; they depend on accounting policies that may differ from rivals'; and they ignore non-financial factors such as staff, brand, markets and management. So they locate where to look but do not settle the verdict.

Result: The ratios paint a sound, profitable, adequately liquid and moderately geared business, but the conclusion is provisional pending comparison with the past and rivals, and is limited by the historic, policy-dependent and non-financial blind spots of ratio analysis.

Typical mistakes

Concluding from one year's ratios with nothing to compare them against.
Ignoring the limitations and the non-financial factors, treating the ratios as the whole story.

Active revision

Using the illustrative ratio set (ROCE 21.4%, acid test 1:1, cash cycle 15 days, gearing 44.6%), write a short assessment of the company's overall position and state three limitations of your analysis.
