A business can report a profit and still run short of cash. It can own valuable assets while carrying too much debt. It can also generate strong sales while losing money on every additional product it sells.
These situations are easier to understand when you know how to read the three main financial statements: the income statement, balance sheet, and cash flow statement.
Each statement answers a different question. The income statement explains financial performance over a period. The balance sheet shows the company’s financial position at a particular date. The cash flow statement explains how cash moved into and out of the business during a period.
The real value comes from reading the statements together. A profit figure alone cannot establish whether a company is financially healthy, and a positive cash balance alone cannot establish whether its operations are profitable.
This guide explains the purpose of each statement, shows the key calculations, and uses one consistent hypothetical business example to demonstrate how the statements connect.
What Are the Three Financial Statements?
Financial statements are structured reports used to communicate information about a business’s financial performance, position, and cash flows.
For US companies reporting under generally accepted accounting principles (GAAP), the three core statements are:
- Income statement: Reports revenues, expenses, and profit or loss over a period.
- Balance sheet: Reports assets, liabilities, and shareholders’ equity at a particular date.
- Cash flow statement: Reports cash inflows and outflows during a period.
A fourth statement, the statement of shareholders’ equity, explains changes in owners’ equity during the reporting period. It is also important when reviewing a complete set of financial statements.
The US Securities and Exchange Commission explains these statements in its Beginner’s Guide to Financial Statements.
The statements are connected, but they are not interchangeable. Revenue is not the same as cash collected, profit is not the same as cash generated, and the value recorded for an asset is not necessarily the amount the company could receive by selling it.
To see why, consider a hypothetical company called Northstar Components.
A Consistent Example: Northstar Components
Northstar Components manufactures and sells equipment parts. We will use its hypothetical annual financial results to demonstrate how the three statements work together.
The figures below are illustrative and are not taken from an actual company’s financial reports.
Simplified annual income statement
| Item | Amount |
|---|---|
| Revenue | $500,000 |
| Cost of goods sold | −$300,000 |
| Gross profit | $200,000 |
| Operating expenses, including depreciation | −$140,000 |
| Operating income | $60,000 |
| Interest expense | −$10,000 |
| Income tax expense | −$12,000 |
| Net income | $38,000 |
Northstar reports $500,000 in revenue and $38,000 in net income.
That tells us the company was profitable under the assumptions in this example. It does not tell us how much cash customers paid during the year, how much cash was spent on equipment, or whether the company borrowed additional money.
We need the balance sheet and cash flow statement to understand those questions.
1. The Income Statement: Did the Business Make a Profit?
The income statement, sometimes called the statement of operations or statement of earnings, measures financial performance over a defined period.
The period might be a month, quarter, fiscal year, or another reporting interval.
Revenue
Revenue represents income recognized from providing goods or services under the applicable accounting rules.
Revenue is not necessarily identical to cash received.
For example, if a business sells $10,000 of goods on credit and recognizes the revenue, the income statement may record the sale before the customer pays. The unpaid amount is generally reflected in accounts receivable, subject to the applicable accounting treatment.
This distinction explains why a company can report substantial revenue while experiencing collection problems.
Cost of goods sold and gross profit
Cost of goods sold (COGS) represents the costs attributed to the goods sold during the period under the company’s accounting policies.
Gross profit is calculated as:
[{Gross profit}={Revenue}-{COGS}]
For Northstar:
[$500{,}000-$300{,}000=$200{,}000]
The company retains $200,000 after the stated cost of goods sold, before operating expenses, interest, taxes, and other items below gross profit.
Gross profit helps reveal how much remains from sales to cover other costs. It should be interpreted in the context of the business model and the consistency of cost classification.
Gross profit margin
Gross profit margin expresses gross profit as a percentage of revenue:
[{Gross margin}={{Gross profit}}{{Revenue}}\times100%]
For Northstar:
[{$200{,}000}{$500{,}000}\times100%=40%]
The company has a gross profit margin of 40% under the example’s assumptions.
This means that for every $1 of revenue, $0.40 remains after the specified costs of goods sold. It does not mean that $0.40 becomes net profit or cash.
Operating expenses and operating income
Operating expenses are costs associated with running the business that are not included in the stated cost of goods sold.
Depending on the company, these may include administrative expenses, selling expenses, research and development, and depreciation associated with operations.
Operating income is calculated here as:
[{Operating income}={Gross profit}-\{Operating expenses}]
For Northstar:
[$200{,}000-$140{,}000=$60{,}000]
Operating income is $60,000 before the interest and income tax expense shown in the example.
Operating margin is:
[{$60{,}000}{$500{,}000}\times100%=12%]
The 12% operating margin can be useful for analyzing how much operating income the company generates relative to revenue. The meaning of a strong or weak margin depends on the industry, business model, cost structure, and period being analyzed.
Net income
Net income is the profit remaining after the expenses and other items included in the income statement have been accounted for.
For Northstar:
[$60{,}000-$10{,}000-$12{,}000=$38{,}000]
Net profit margin is:
[{$38{,}000}{$500{,}000}\times100%=7.6%]
Northstar earns $38,000 in net income, equivalent to 7.6% of revenue under the example’s assumptions.
That figure describes accounting profitability for the period. The company may still have spent cash on equipment, carried unpaid customer invoices, repaid debt, or experienced other cash movements not revealed by net income alone.
What the income statement does not tell you
The income statement does not, by itself, establish:
- How much cash the company has at the end of the period.
- How quickly customers pay their invoices.
- How much debt is outstanding.
- How much cash was spent on equipment.
- Whether the company can meet upcoming payments.
Those questions require information from the other statements and the accompanying notes.
2. The Balance Sheet: What Does the Business Own and Owe?
The balance sheet reports a company’s financial position at a specific date.
Unlike the income statement, which covers a period, the balance sheet is a snapshot. It shows recognized assets, liabilities, and shareholders’ equity at that reporting date.
The fundamental accounting equation is:
[{Assets}={Liabilities}+{Shareholders’ equity}]
The equation must balance under the accounting records used to prepare the statement.
Assets
Assets are resources recognized by the company under the applicable accounting framework.
Common examples include:
- Cash and cash equivalents.
- Accounts receivable.
- Inventory.
- Property, plant, and equipment.
- Certain financial investments and other recognized assets.
Some assets are classified as current, while others are noncurrent. Current classifications generally relate to the applicable operating cycle and accounting rules rather than serving as a guarantee that every asset can immediately be converted into cash.
Liabilities
Liabilities represent recognized obligations of the company.
Examples may include:
- Accounts payable.
- Accrued expenses.
- Borrowings.
- Certain lease liabilities.
- Other contractual or statutory obligations.
Some liabilities are current and others noncurrent, depending on the applicable classification requirements and the circumstances at the reporting date.
Shareholders’ equity
Shareholders’ equity is the residual interest in the company’s recognized assets after deducting its recognized liabilities.
It may include contributed capital, retained earnings, and other equity components, depending on the company’s structure and accounting framework.
Equity is not the same as the amount of cash invested in the company, and it is not necessarily equal to what shareholders would receive if the company were sold.
A Hypothetical Balance Sheet for Northstar Components
Suppose Northstar has the following balances at the end of the year.
| Balance sheet item | Amount |
|---|---|
| Assets | |
| Cash | $25,000 |
| Accounts receivable | $58,000 |
| Inventory | $37,000 |
| Net property and equipment | $115,000 |
| Total assets | $235,000 |
| Liabilities | |
| Accounts payable | $30,000 |
| Debt outstanding | $62,000 |
| Total liabilities | $92,000 |
| Shareholders’ equity | $143,000 |
| Total liabilities and equity | $235,000 |
The balance sheet balances:
[$235{,}000=$92{,}000+$143{,}000]
The company has $235,000 in recognized assets and $92,000 in recognized liabilities, leaving $143,000 in shareholders’ equity.
These figures do not automatically determine the company’s market value. Market valuation can depend on expected cash flows, risk, growth, intangible assets, market conditions, and many other factors.
What the balance sheet reveals
Several questions arise from Northstar’s balance sheet.
First, only $25,000 is shown as cash. The company has more assets, but receivables and inventory may take time to convert into available cash.
Second, it has $62,000 of debt outstanding. The balance sheet alone does not provide the full repayment schedule, interest rate, covenant terms, or maturity dates. Those details may appear in the notes or other disclosures.
Third, $58,000 in accounts receivable deserves attention. Analysts may want to know whether customers pay on time and whether overdue invoices or concentration in a small number of customers create collection risk.
The balance sheet provides starting points for analysis, not every answer.
Working Capital and the Current Ratio
Working capital is a common measure of short-term financial resources.
[{Working capital}={Current assets}-{Current liabilities}]
Suppose Northstar’s current assets consist of cash, accounts receivable, and inventory:
$25,000 + $58,000 + $37,000 = $120,000.
Assume the company has $30,000 of accounts payable and $10,000 of other current liabilities, for total current liabilities of $40,000.
Working capital would be:
[$120{,}000-$40{,}000=$80{,}000]
The current ratio is:
[{Current ratio}={Current assets}{Current liabilities}]
For Northstar:
[{$120{,}000}{$40{,}000}=3.0]
The current ratio is 3.0 under these assumptions, meaning the company has $3 in current assets for every $1 in current liabilities.
That does not prove that all short-term obligations can be paid comfortably. Inventory may be difficult to sell, receivables may be overdue, or cash may be restricted.
Working capital and liquidity ratios should be interpreted alongside the actual quality and timing of assets and liabilities.
3. The Cash Flow Statement: Where Did the Cash Go?
The cash flow statement reports changes in cash and cash equivalents during a period, organized into operating, investing, and financing activities under the applicable reporting framework.
It is particularly useful because accounting profit and cash generation can diverge.
For example, a business may recognize revenue from a sale before the customer pays. It may also recognize depreciation as an expense even though depreciation is not a current-period cash payment.
The cash flow statement helps explain these differences.
Operating activities
Operating cash flow reflects cash flows associated with the company’s operating activities.
Under the indirect method, operating cash flow commonly begins with net income and adjusts for noncash items and changes in operating assets and liabilities.
Common adjustments include:
- Adding back depreciation and amortization where appropriate.
- Subtracting increases in accounts receivable.
- Subtracting increases in inventory.
- Adding increases in accounts payable.
- Making other adjustments required by the applicable accounting framework.
The exact presentation depends on the business and accounting requirements. Not every cash flow statement uses the same level of detail or classification.
Investing activities
Investing cash flows commonly include purchases and sales of long-lived assets and certain investments.
For example, cash spent purchasing manufacturing equipment is generally shown as an investing outflow for a company preparing a conventional US GAAP statement of cash flows.
Selling qualifying assets may produce an investing inflow.
Investing cash flow is therefore not automatically negative or positive in a healthy business. A company investing in expansion may have negative investing cash flow because it is spending money on assets expected to support future activity.
Financing activities
Financing cash flows generally include cash related to borrowing, repaying principal, issuing shares, repurchasing shares, and distributing dividends, subject to the applicable reporting framework.
For example, when a company borrows $20,000, it receives cash from a financing activity. When it repays $8,000 of loan principal, cash decreases through a financing outflow.
Interest and dividend classification can depend on the applicable accounting framework and accounting policy. A financial statement should be read according to its stated reporting basis rather than assuming every company classifies every item identically.
Northstar’s Cash Flow Statement
Now connect the income statement and balance sheet to a hypothetical cash flow statement for the same year.
Cash flow from operating activities
Northstar reports $38,000 of net income. Assume the following adjustments:
| Operating cash flow item | Amount |
|---|---|
| Net income | $38,000 |
| Add: depreciation expense | $10,000 |
| Less: increase in accounts receivable | −$18,000 |
| Less: increase in inventory | −$7,000 |
| Add: increase in accounts payable | $5,000 |
| Net cash from operating activities | $28,000 |
The calculation is:
[$38{,}000+$10{,}000-$18{,}000-$7{,}000+$5{,}000=$28{,}000]
Northstar reports $38,000 in net income but generates $28,000 in operating cash under these assumptions.
The difference is largely explained by depreciation and changes in working capital.
Depreciation reduced accounting profit but did not involve an equivalent current-period cash payment. Meanwhile, the increase in accounts receivable means part of the recognized revenue has not yet been collected, and the inventory increase has used resources that have not yet been recovered through sales.
Accounts payable increased by $5,000, which means the company recognized or incurred additional supplier obligations that had not yet been paid in cash under this simplified example.
Cash flow from investing activities
Assume Northstar purchased equipment costing $25,000 and had no other investing cash flows in the example.
| Investing cash flow item | Amount |
|---|---|
| Equipment purchases | −$25,000 |
| Net cash used in investing activities | −$25,000 |
Northstar invested $25,000 in equipment.
The cash outflow is not necessarily a $25,000 expense on the income statement in the same year. The equipment may be capitalized as an asset and depreciated over its useful life under the applicable accounting rules.
This is one reason capital spending and accounting profit differ.
Cash flow from financing activities
Assume the company borrowed $20,000, repaid $8,000 of debt principal, and paid $5,000 in dividends.
| Financing cash flow item | Amount |
|---|---|
| New borrowing | $20,000 |
| Principal repayments | −$8,000 |
| Dividends paid | −$5,000 |
| Net cash from financing activities | $7,000 |
Northstar received a net $7,000 from the specified financing activities.
The company raised new debt, but it also repaid principal and distributed cash to shareholders. The net result was positive financing cash flow for the year under these assumptions.
Reconcile the change in cash
Combining the three categories:
| Cash flow category | Amount |
|---|---|
| Operating activities | $28,000 |
| Investing activities | −$25,000 |
| Financing activities | $7,000 |
| Net increase in cash | $10,000 |
If the company’s beginning cash balance was $15,000, its ending cash balance becomes:
[$15{,}000+$10{,}000=$25{,}000]
That agrees with the $25,000 cash balance shown on the illustrative ending balance sheet.
The relationship among the statements is now visible: the company reports $38,000 in net income, generates $28,000 in operating cash, invests $25,000 in equipment, and receives $7,000 net from the stated financing activities. Its cash balance increases by $10,000.
This is why the three financial statements need to be analyzed together.
How the Three Financial Statements Connect
The statements are different views of the same underlying business activity.
Net income affects equity
Under the assumptions in this example, net income increases retained earnings, while dividends reduce the amount retained in the company.
The simplified change in equity is:
Beginning equity + Net income − Dividends = Ending equity.
Northstar’s opening equity would be $110,000 under this simplified reconciliation:
$110,000 + $38,000 − $5,000 = $143,000.
This agrees with the ending equity balance used in the hypothetical balance sheet.
Other equity movements, such as share issuance, share repurchases, and other comprehensive income, would need to be included if they occurred.
Depreciation affects profit and asset values
Depreciation is an accounting allocation of an asset’s depreciable cost over its useful life under the applicable rules.
It reduces income through the income statement and generally affects the carrying amount of property and equipment on the balance sheet.
Under the indirect cash flow method, depreciation is added back to net income when reconciling operating cash flow because it is a noncash expense in the period.
It is not added back because the equipment was free. The equipment purchase involved a cash outflow when acquired, which is reflected separately in the example’s investing activities.
Borrowing affects both cash and liabilities
When the company borrows $20,000, cash increases and debt increases, assuming no additional transaction effects.
When it repays $8,000 of principal, cash decreases and the debt balance falls.
These transactions change the balance sheet and cash flow statement, but borrowing and principal repayment are not themselves revenue and operating expenses in the income statement.
Interest expense, on the other hand, affects reported profit under the example’s classification.
Customer collections affect receivables and cash
If a customer pays an invoice that was previously recorded as accounts receivable, cash increases while accounts receivable decreases.
The collection itself does not generally create new revenue at that moment if the revenue was already recognized when the original sale was recorded.
This distinction is essential for understanding why revenue and cash collections may differ during a reporting period.
Common Mistakes When Reading Financial Statements
Mistake 1: Assuming net income equals available cash
The company may have recognized sales that customers have not paid, invested in inventory, purchased equipment, or repaid debt. Net income alone does not show whether enough cash is available to cover future payments.
Mistake 2: Treating a larger balance sheet as proof of a stronger business
Assets and liabilities should be examined for quality, liquidity, recoverability, and risk. An increase in assets funded by substantial borrowing does not necessarily mean the business is financially healthier.
Mistake 3: Comparing companies without considering accounting and business differences
Different industries have different operating models, capital needs, and margin structures. Accounting policies and estimates may also affect comparisons.
A financial ratio that is meaningful for a retailer may be less informative for a software company or a capital-intensive manufacturer.
Mistake 4: Ignoring the notes to the financial statements
The notes can explain accounting policies, debt maturities, commitments, contingencies, segment information, related-party transactions, and other details necessary to interpret the reported figures.
The statements should not be analyzed independently of their accompanying disclosures.
Mistake 5: Assuming an audit eliminates all uncertainty
An audit provides assurance under its applicable standards and scope, but it does not guarantee that a business will be profitable, remain solvent, or perform as expected in the future.
The SEC explains that Form 10-K includes financial statements and accompanying disclosures. It also describes the role of the auditor and the sections that provide information about business risks and management’s discussion of results.
See Investor.gov: How to Read a 10-K.
Mistake 6: Looking at only one year
One year’s results may reflect unusual events, seasonal changes, acquisitions, or temporary cost pressures.
Where available, compare multiple reporting periods and investigate material movements rather than simply extrapolating the latest figures.
How to Read the Financial Statements of a Public Company
For a US public company, its Form 10-K is a useful place to begin.
The report usually provides business information, risk factors, management’s discussion and analysis, financial statements, and supporting notes.
The SEC’s How to Read a 10-K guide explains these sections and how they contribute to understanding the company.
A practical reading sequence is:
- Read the business description to understand how the company earns revenue.
- Review the risk factors to identify important business and market risks.
- Read management’s discussion and analysis to understand changes in performance and liquidity.
- Examine the income statement, balance sheet, and cash flow statement.
- Read the notes for debt terms, accounting policies, commitments, and significant estimates.
- Compare the results with prior years and investigate material differences.
Do not treat management’s explanations as a substitute for your own analysis. Compare narrative statements with the figures and disclosures to understand whether the evidence supports the claims being made.
Frequently Asked Questions
What are the three main financial statements?
The three main statements are the income statement, balance sheet, and cash flow statement. A complete set of financial statements also includes a statement of shareholders’ equity and related notes under the applicable reporting requirements.
Which financial statement should I read first?
The income statement is a useful starting point for understanding profitability, but the best sequence depends on your question. For liquidity and debt risk, the balance sheet and cash flow statement may be equally important.
Can a company be profitable but have negative cash flow?
Yes. Revenue may not yet be collected, inventory may absorb cash, or operating liabilities may be paid during the period. Capital expenditures and debt repayments can also reduce cash even when reported net income is positive.
Why is depreciation added back in the operating cash flow statement?
Under the indirect method, net income includes depreciation expense even though depreciation itself is not a current-period cash payment. It is added back to reconcile accounting profit to operating cash flow. The original asset purchase still requires cash and is reflected according to the applicable cash flow classification.
What is the difference between a balance sheet and an income statement?
A balance sheet shows assets, liabilities, and equity at a specific date. An income statement reports revenue, expenses, and profit or loss over a period.
Are all financial statements prepared using US GAAP?
No. US GAAP applies to many US reporting entities, but other entities may use different applicable accounting frameworks, such as International Financial Reporting Standards (IFRS). The reporting basis should be identified before comparing financial statements across jurisdictions.
The Financial Accounting Standards Board identifies its Accounting Standards Codification as the authoritative source of nongovernmental US GAAP. The standards applicable to a particular entity depend on its reporting circumstances.
Conclusion
The income statement, balance sheet, and cash flow statement provide complementary views of a company’s financial condition.
The income statement explains profitability, the balance sheet reveals financial position, and the cash flow statement shows how cash changed during the period. Reading them together helps explain why a company can report profits while experiencing liquidity pressure, or why a business can borrow money and increase its cash balance without generating additional operating profit.
Start with the purpose of each statement, verify how the figures connect, and use the notes and multi-period comparisons to understand the context. A sound financial analysis does not rely on a single number—it examines the relationship among profitability, assets, liabilities, and cash flows.
