8 Introduction to Financial Statement Analysis

Learn how to read connected financial statements, calculate key performance ratios, interpret a worked example, and organize a practical company analysis.

Questions financial analysis answers

turns accounting figures into evidence about a company’s performance and financial condition. It helps answer four central questions: Is the company profitable? Can it meet near-term bills? Can it manage longer-term obligations? How effectively does it use its resources?

Read the statements together

Each statement provides a different view, so read them together rather than relying on one figure or .

The reports revenue, expenses, and profit or loss over a period.
The reports assets, liabilities, and owners’ equity at a specific date. Its equation is:

\text{Assets} = \text{Liabilities} + \text{Equity}

The reports cash movements from operating, investing, and financing activities over a period.
The statement of changes in equity explains changes in owners’ interests over a period.

Profit is not the same as cash. Under accrual accounting, revenue or expenses may be recorded before cash is received or paid. Read the statements alongside the notes and management’s discussion to understand the figures in context.

Use ratios with context

A relates two financial statement amounts. Ratios help track a company over time and compare it with similar businesses, but they are not definitive verdicts. Accounting methods, seasonality, business models, and industry norms can affect results, so a high or low may mean different things in different contexts.

For ratios that relate income over a period to a balance-sheet amount, average beginning and ending balances are often more representative than the ending balance alone.

Assess profitability

Profitability ratios show how much profit a company generates from sales, assets, or owners’ investment. Each margin focuses on a different point in the movement from revenue to profit.

shows the share of sales remaining after the direct cost of goods sold:

\text{Gross profit margin} = \frac{\text{Revenue} - \text{Cost of goods sold}}{\text{Revenue}}

Operating margin shows the share of sales remaining after operating expenses, before interest and income taxes:

\text{Operating margin} = \frac{\text{Operating income}}{\text{Revenue}}

Net profit margin shows the share of sales left as profit after expenses, including interest and taxes:

\text{Net profit margin} = \frac{\text{Net income}}{\text{Revenue}}

Returns relate profit to resources or owners’ investment. indicates how effectively assets generate profit, while measures profit relative to owners’ investment:

\text{ROA} = \frac{\text{Net income}}{\text{Average total assets}}

\text{ROE} = \frac{\text{Net income}}{\text{Average owners’ equity}}

A high ROE can reflect strong performance, but it can also result from a small equity base or substantial borrowing.

Check near-term payment capacity

is the ability to pay obligations due soon. gives a dollar measure, while ratios compare current assets with current liabilities.

\text{Working capital} = \text{Current assets} - \text{Current liabilities}

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

The is a stricter measure because it excludes inventory and other less readily available current assets:

\text{Quick ratio} = \frac{\text{Cash} + \text{Short-term investments} + \text{Accounts receivable}}{\text{Current liabilities}}

A above $1$ means current assets exceed current liabilities on the balance-sheet date. It does not prove that the company can readily pay every bill. Consider how quickly receivables are collected, whether inventory can be sold, and when liabilities come due.

Evaluate longer-term obligations

concerns a company’s longer-term ability to meet financial commitments. Debt can help fund growth, but borrowing also creates required payments and increases financial risk.

The compares creditor financing with owners’ financing. In this guide, it uses total liabilities, although some calculations use interest-bearing debt instead; check how a particular source defines debt.

\text{Debt-to-equity ratio} = \frac{\text{Total liabilities}}{\text{Owners’ equity}}

indicates how many times operating income covers interest expense. A lower or falling result may signal less capacity to absorb a decline in earnings.

\text{Interest coverage} = \frac{\text{Operating income}}{\text{Interest expense}}

Interpret these measures alongside cash flow, debt maturities, and the company’s industry and business risks.

Assess resource use

, or activity, ratios relate sales or costs to assets and operating balances. measures revenue generated per dollar of assets:

\text{Total asset turnover} = \frac{\text{Revenue}}{\text{Average total assets}}

estimates how many times inventory is sold and replaced during the period:

\text{Inventory turnover} = \frac{\text{Cost of goods sold}}{\text{Average inventory}}

Average inventory is commonly calculated as:

\text{Average inventory} = \frac{\text{Beginning inventory} + \text{Ending inventory}}{2}

Higher turnover is not always better. Unusually low may indicate slow-moving stock, while very high turnover may mean the company risks running short. Compare turnover with past periods and similar businesses.

Work through a retailer example

Suppose a retailer reports annual revenue of $\$500{,}000$ , cost of goods sold of $\$300{,}000$ , operating income of $\$60{,}000$ , net income of $\$40{,}000$ , and interest expense of $\$10{,}000$ . Average total assets are $\$400{,}000$ , average equity is $\$200{,}000$ , and average inventory is $\$40{,}000$ . At year-end, current assets are $\$120{,}000$ , including $\$40{,}000$ of inventory; current liabilities are $\$80{,}000$ , and total liabilities are $\$240{,}000$ .

: $(\$500{,}000 - \$300{,}000) \div \$500{,}000 = 40\%$ .
Operating margin: $\$60{,}000 \div \$500{,}000 = 12\%$ ; net profit margin: $\$40{,}000 \div \$500{,}000 = 8\%$ .
ROA: $\$40{,}000 \div \$400{,}000 = 10\%$ ; ROE: $\$40{,}000 \div \$200{,}000 = 20\%$ .
: $\$120{,}000 - \$80{,}000 = \$40{,}000$ ; : $\$120{,}000 \div \$80{,}000 = 1.5$ ; : $(\$120{,}000 - \$40{,}000) \div \$80{,}000 = 1.0$ .
: $\$240{,}000 \div \$200{,}000 = 1.2$ ; : $\$60{,}000 \div \$10{,}000 = 6$ times.
: $\$500{,}000 \div \$400{,}000 = 1.25$ times; : $\$300{,}000 \div \$40{,}000 = 7.5$ times.

These results describe several aspects of the business, not a complete judgment. Interpret them by comparison with the retailer’s earlier results and relevant competitors, and by considering explanations in the financial statement notes and management’s discussion.

Follow a practical analysis sequence

Use a consistent sequence to organize an analysis:

Identify the reporting period and confirm that figures being compared cover comparable periods.
Review revenue, margins, and net income for trends; investigate unusually large changes.
Check and the timing of cash receipts and payments.
Examine debt, interest costs, and the company’s ability to generate operating cash.
Assess turnover measures in light of the company’s operations and industry.
Read the notes, audit report, and management’s discussion for accounting policies, estimates, risks, and explanations behind the figures.

Public-company filings include these materials. The SEC explains that its review process does not itself guarantee a filing’s accuracy.

Bring the findings together

Combine the , , , and accompanying disclosures rather than relying on a single measure. Profitability measures returns; measures near-term payment capacity; measures longer-term financial risk; and measures how effectively resources support operations.

Ratios are most informative when calculated consistently, compared across time and with appropriate peers, and interpreted alongside cash flows and the company’s context.
