Start with the question each statement answers
Profit is not the same as cash, and neither is the same as the cash balance at year-end. The income statement, balance sheet, and cash-flow statement describe different parts of the same business. Reading them together helps explain how a profitable company can still finish a year with less cash.
This introduction uses a simplified, hypothetical operating company under U.S. accounting conventions. It is a map for reading, not a complete set of accounts. The statement of shareholders’ equity and the notes matter too; “three statements” is not a claim that an annual report contains only three.
A period of activity meets a snapshot
The income statement reports revenue, expenses, and profit or loss over a period. The cash-flow statement follows cash movements over that period. The balance sheet reports assets, liabilities, and shareholders’ equity on a particular date. On that balance sheet, assets equal liabilities plus shareholders’ equity. A full-year result and a year-end balance therefore answer different questions. The SEC’s financial-statement introduction explains these roles.
Think of a manufacturer selling equipment on credit. Revenue may be recorded before the customer pays. The amount still owed appears as a receivable, an asset on the balance sheet. Collection later turns that receivable into cash; it is not a second sale. Timing connects the statements without making their totals interchangeable.
Profit also contributes to equity through retained earnings. But retained earnings is an accounting balance, not a separate bank account. Money kept in the business may have gone into inventory or equipment. Dividends and other equity movements must also be considered when following the change in shareholders’ equity. See the SEC’s balance-sheet guide.
Follow profit into operating cash
Under the indirect method, the operating section starts with net income and adjusts it to operating cash flow. Some adjustments concern expenses without a matching current-period cash payment. Depreciation, for example, allocates an asset’s cost over time; adding it back does not make the equipment free.
Other adjustments concern operating assets and liabilities. Inventory can absorb cash before goods are sold. Supplier bills can be recognized before they are paid. These timing differences help explain why profit and operating cash differ. Use the cash-flow statement’s signed adjustments rather than assuming every change between two balance sheets is a cash movement. Acquisitions and other noncash changes can complicate that comparison.
The SEC’s cash-flow guide introduces the indirect method. For the detailed reconciliation, continue to From net income to operating cash flow.
Reinvestment and financing explain more of the journey
Buying a long-lived machine for cash normally appears in investing activities, while its depreciation affects earnings over time. Reinvesting in inventory works differently: its cash effects generally belong in operations. “Reinvestment” is not one universal line on the cash-flow statement.
Financing activities include transactions such as borrowing, repaying loan principal, and paying cash dividends. Borrowing can increase cash without creating revenue. Paying a dividend uses cash without being an operating expense. The three sections separate these different reasons for cash to move.
Financing cash flow is not free cash flow. We spell out “financing” here to avoid confusing the two. Free cash flow is a separately defined measure, often operating cash flow less capital expenditures. It is not another section to add to the cash reconciliation, and it is not automatically cash available for dividends. SEC staff guidance, Question 102.07, explains its definition and limitations.
Reconcile the beginning and ending balances
Here is a hypothetical example, not Apple or another actual issuer. All amounts are USD millions. Flows cover January 1 through December 31 of an imaginary year; opening and closing balances refer to those boundaries. Assume the same cash definition throughout and no restricted cash.
The company begins with 50. It reports net income of 24, adds back 10 of depreciation, and records a net operating-asset and liability adjustment of minus 4. With no other operating adjustments in this simplified example, operating cash flow is 30.
It spends 20 on equipment, its only investing cash flow. It pays 5 in dividends and repays 3 of loan principal, its only financing cash flows. Assume it also holds foreign-currency cash: exchange-rate changes add 1 when that cash is translated into the reporting currency. The complete bridge is 50 + 30 − 20 − 8 + 1 = 53.
Cash increased by 3, not by the 24 of profit or the 30 of operating cash. Each number answers a different question. In words, opening cash plus signed operating, investing, and financing cash flows, plus the exchange-rate effect, gives closing cash. Do not subtract the dividend again: it is already included in financing.
Check what the cash total includes
“Cash” in that bridge is shorthand for the precise total being reconciled. Cash equivalents are qualifying short-term, highly liquid investments, not every marketable security. Read the company’s accounting policy.
Under U.S. GAAP, the cash-flow reconciliation includes cash, cash equivalents, and amounts described as restricted cash or restricted cash equivalents. The balance sheet may show those amounts in more than one place. Use the accompanying reconciliation rather than assuming the headline cash line must match. Restrictions can also mean that part of the total is unavailable for general use. FASB’s restricted-cash update explains the scope and the separate exchange-rate reconciliation.
A matching total is an arithmetic check, not proof that a dividend is safe. Next, try the Apple FY2024 filing lab, a historical exercise rather than a current company assessment. It follows the source rows in more detail; this introduction does not update its figures.
