Financial statement analysis
Use ratios and trends to explain business drivers, not to label a company from one number. Check comparability, earnings quality and cash conversion before drawing a liquidity, profitability or solvency conclusion.
Select a ratio for the decision
- Collection speed
- Days sales outstanding = average receivables ÷ annual credit sales × 365.
- Interest coverage
- EBIT ÷ interest expense.
- Return on equity
- Net income ÷ average equity.
Use comparable periods and accounting policies. No single ratio establishes good liquidity or sustainable performance.
See the decision
Revenue grows while cash collection slows
Two comparable illustrative years have revenue of $800,000 and $1,000,000, all credit sales. Average receivables are $80,000 and $150,000. Use a 365-day year.
Days sales outstanding
- Year 136.5 days
- Year 254.75 days
Investigate credit terms and aging before concluding that growth improved liquidity. These ratios identify a question, not its cause.
How to apply these ideas
1. Comparable statements
Align periods, accounting policies and the scope of the business.
Acquisitions, disposals and policy changes can break year-to-year comparisons. Common-size statements scale lines to a common base; trend analysis compares the same measure across time. Neither removes a change in the underlying business automatically.
Watch for: Calling all reported revenue growth organic growth.
2. Ratio selection
Match the measure to the decision.
Liquidity concerns near-term obligations; leverage and coverage address financing risk; turnover describes asset use; margins describe income per sales dollar. Use average balance-sheet amounts where the flow-to-stock ratio calls for them and state your convention.
Watch for: Comparing a period flow with an unexplained point-in-time balance.
3. Profitability drivers
Break return into margin, turnover and financing effects.
A higher return on equity can reflect better operations or more leverage. Follow the components before judging quality. A common-size income statement helps locate the margin change but does not prove why it occurred.
Watch for: Treating higher ROE as unqualified evidence of better operations.
4. Earnings and cash
Check whether profit turns into recurring operating cash.
Investigate receivable aging, inventory growth, unusual gains and changes in estimates. A single period’s cash shortfall can reflect growth or seasonality, so combine trend evidence with the notes and business context.
Watch for: Assuming accrual profit is immediately available for debt service.

Make the comparison meaningful before calculating ratios
Horizontal analysis compares a line across periods. Common-size analysis expresses each line relative to a base, such as revenue for an income statement or total assets for a balance sheet. These approaches answer different questions: sales growth shows scale, while an expense as a percentage of sales shows how the cost burden changed. Use both before attributing a movement to efficiency.
Check period length, seasonality, acquisitions, currency, accounting policies and unusual transactions. A company acquired halfway through the year may add substantial closing assets but only half a year of earnings. Comparing that income with ending assets can depress a return measure for a timing reason. Prefer consistent definitions and explain unavoidable limitations rather than treating every ratio movement as an operating change.
Choose ratios that answer the stakeholder’s question
A supplier may care about near-term payment capacity, a lender about debt service and downside protection, and an equity investor about sustainable returns and growth. Start with the decision, then choose a small set of related measures. No single “good ratio” applies to every business model, industry or season.
Use average balance-sheet balances when a period flow is compared with the resources employed over that period and the data permits it. For turnover, keep the sales or cost basis consistent with the asset: receivable turnover commonly uses credit sales, while inventory turnover uses cost of goods sold. Report a proxy explicitly when only total sales or ending balances are available.
| Purpose | Examples | Interpretation check |
|---|---|---|
| Liquidity | Current ratio, quick ratio | Composition and realizability of current assets |
| Activity | Receivable and inventory turnover | Use a consistent flow and average balance |
| Solvency | Debt ratios and interest coverage | Maturities, variable rates and off-balance-sheet commitments |
| Profitability | Margins, ROA and ROE | Policy changes, unusual items and asset base |
| Market perspective | EPS and valuation multiples | Expectations and share-count changes, not only current profit |
Decompose profitability instead of stopping at the percentage
Gross margin can change because of price, product mix, input costs, production efficiency or inventory accounting. Operating margin adds selling, administrative and other operating expenses. Net margin also reflects financing and tax effects. A lower tax rate can improve net margin while the underlying operating margin deteriorates.
Under consistent definitions, ROE can be decomposed into net margin × asset turnover × equity multiplier. A rise in leverage can increase ROE without improving operating efficiency and can amplify losses. Compare the components and the risk exposure, not just the final percentage. Changes in buybacks or accumulated losses can also shrink equity and make ROE difficult to interpret.
Test earnings against cash conversion and supporting balances
Revenue recognized on credit creates a receivable; a build in inventory consumes resources before a sale. Strong reported growth alongside slower collections or rising inventory can increase funding needs. Inspect receivable aging, credit terms, return patterns and obsolete inventory. The pattern is a reason to investigate, not proof of manipulation.
Assess whether earnings depend on recurring operations or on unusual gains, releases of estimates and changes in classification. Cash flow can also be temporarily improved by delaying suppliers or collecting advances. An operating-cash-flow figure is therefore useful evidence, but it still needs context about working capital and the sustainability of the actions behind it.
Identify inflation, currency and accounting effects
Inflation can increase nominal revenue while physical volume is flat, and historical asset costs can distort comparisons with newer assets. Currency translation can change reported revenue without an equivalent change in local-currency operations. Separate the economic movement from the reporting translation when information is available.
Accounting differences in inventory, depreciation, development costs or impairment can affect comparability. Read policies and reconcile adjustments transparently; do not selectively remove only unfavorable items. An adjusted measure is useful only if the reader can see what changed and why. The Part 1 reporting lesson explains how those measurement choices enter the statements.
Work it through
Worked example: Revenue grows while cash collection slows
Two comparable illustrative years have revenue of $800,000 and $1,000,000, all credit sales. Average receivables are $80,000 and $150,000. Use a 365-day year.
| Measure | Year 1 | Year 2 |
|---|---|---|
| Revenue | $800,000 | $1,000,000 |
| Average receivables | $80,000 | $150,000 |
| Receivable turnover | 10.00× | 6.67× |
| Days sales outstanding | 36.5 days | 54.75 days |
- 1
Year 1 DSO = 80,000 / 800,000 × 365 = 36.5 days.
- 2
Year 2 DSO = 150,000 / 1,000,000 × 365 = 54.75 days. Revenue grew 25%, but collection time increased 18.25 days.
Investigate credit terms and aging before concluding that growth improved liquidity. These ratios identify a question, not its cause.
Work through the alternatives
More worked cases: financial statement analysis
Original teaching scenarios. Each case states its assumptions, shows the working and explains the limits of the conclusion.
The same ROE can come from different operating models
Two businesses each report 15% ROE using consistent average balances. A has 10% net margin, 1.0 asset turnover and 1.5 equity multiplier. B has 5% net margin, 1.5 turnover and 2.0 multiplier.
| Component | Business A | Business B |
|---|---|---|
| Net margin | 10% | 5% |
| Asset turnover | 1.0× | 1.5× |
| Equity multiplier | 1.5× | 2.0× |
| ROE | 15% | 15% |
- A: 10% × 1.0 × 1.5 = 15%. B: 5% × 1.5 × 2.0 = 15%.
- B compensates for the lower margin with higher turnover and leverage. Analyze financing risk and the sustainability of the turnover advantage.
What the result means: Equal ROE does not imply equal operating quality or equal risk.
Revenue grows while operating margin falls
Revenue rises from $500,000 to $600,000. Cost of goods sold rises from $300,000 to $390,000, and operating expenses from $150,000 to $165,000. Ignore other income, interest and tax.
| Measure | Earlier year | Later year |
|---|---|---|
| Revenue | $500,000 | $600,000 |
| Gross profit | $200,000 | $210,000 |
| Gross margin | 40% | 35% |
| Operating income | $50,000 | $45,000 |
| Operating margin | 10% | 7.5% |
- Revenue increased 20%, but cost of goods sold increased 30%. Gross profit increased only $10,000.
- Operating expenses increased $15,000, more than the additional gross profit. Operating income therefore fell $5,000.
What the result means: Investigate price, mix and unit-cost drivers. Sales growth alone does not support a conclusion that profitability improved.
Practice this topic
Check your understanding
Try each short application before opening its explanation. These are original learning checks, not official exam questions or a score prediction.
1. Cash is $20,000, short-term investments $10,000, net receivables $50,000 and inventory $40,000. Current liabilities are $80,000. Using those first three assets as quick assets, what is the quick ratio?
Show answer and explanation
1.0×.
Quick assets total $80,000. Inventory is excluded under the stated definition; including it would produce the current ratio of 1.5×.
2. Credit sales are $720,000 and average receivables are $90,000. On a 360-day convention, what is DSO?
Show answer and explanation
45 days.
Turnover is 8×; 360 ÷ 8 = 45. State the day-count convention instead of mixing 360 and 365.
3. Could ROE rise after a debt-funded share repurchase even with unchanged operating income?
Show answer and explanation
Yes.
The equity base can shrink while leverage rises. Interest effects and the period definition also matter; a higher ROE is not sufficient evidence of operating improvement.
Questions about financial statement analysis
- Is there a universally good current ratio?
- No. Industry, seasonality, asset quality and payment timing matter. A high ratio can include slow or uncollectible assets. Compare suitable peers and the company’s own history.
- Why use average receivables?
- Sales accumulate throughout a period while receivables are a balance at a date. An average better aligns the denominator or numerator with the period flow, although a simple opening/closing average can still miss seasonality.
