What is a cash flow statement?
By MacrosLM Team · Reviewed by Togzhan Shagirova, Subject Matter Expert in Audit and Assurance
A cash flow statement is a financial report that shows how much cash a business generated and spent during a period, broken into operating, investing, and financing activities. Unlike the income statement, which recognizes revenue and expenses when earned or incurred, the statement of cash flows tracks actual cash movement — why a profitable company can still run short on cash, and why analysts treat it as the tiebreaker when earnings look strong but cash doesn't follow. Its structure is set by IAS 7 (IFRS) and, for US filers, US GAAP as maintained by the FASB.
The three sections of the statement of cash flows
Every cash flow statement organizes activity into three sections, each answering a different question about where cash came from.
| Section | What it captures | Typical line items |
|---|---|---|
| Operating activities | Cash generated by core business operations | Net income, depreciation/amortization, changes in receivables, inventory, payables |
| Investing activities | Cash used to acquire or sell long-term assets | Capital expenditures, purchases/sales of equipment, acquisitions, investment purchases |
| Financing activities | Cash exchanged with lenders and owners | Debt issuance/repayment, share issuance/buybacks, dividends paid |
Operating activities get the most scrutiny because they reflect the cash-generating power of the core business, separate from investment decisions or financing structure. Strong net income paired with persistently negative operating cash flow is a common warning sign in credit analysis and quality of earnings work.
Direct vs. indirect method — and why indirect wins
The direct method lists actual cash receipts and payments (cash collected from customers, cash paid to suppliers and employees) — intuitive, but it requires tracking cash transactions separately from the general ledger. The indirect method starts with net income and adjusts for non-cash items and working capital changes to arrive at operating cash flow. Almost every company uses the indirect method because it can be built directly from the income statement and balance sheet without extra cash-tracking infrastructure. Investing and financing sections are identical under both methods — only the operating section's presentation differs.
How the statement reconciles net income to the change in cash
The indirect method's core logic is a bridge: start with an accrual-basis number (net income) and walk it back to a cash-basis number (change in cash). The adjustments fall into two buckets: non-cash items (add back expenses that reduced net income but didn't consume cash, like depreciation, amortization, and stock-based compensation) and working capital changes (adjust for timing gaps — a rise in accounts receivable subtracts from cash flow, a rise in accounts payable adds to it). The result should tie out: net income, plus or minus adjustments across all three sections, equals the actual change in cash for the period. This reconciliation is also the starting point for a 13-week cash flow forecast, which projects the same logic forward on a rolling basis.
Worked example: Acme Manufacturing (illustrative)
Acme Manufacturing is a hypothetical company used here for illustration only — the figures are simplified and self-consistent, not drawn from any real filing.
| Line item | Amount |
|---|---|
| Net income | 500,000 |
| Add: Depreciation & amortization | 120,000 |
| Less: Increase in accounts receivable | (80,000) |
| Add: Decrease in inventory | 40,000 |
| Add: Increase in accounts payable | 30,000 |
| Net cash from operating activities | 610,000 |
| Purchase of equipment | (250,000) |
| Sale of old equipment | 20,000 |
| Net cash used in investing activities | (230,000) |
| Repayment of long-term debt | (100,000) |
| Dividends paid | (50,000) |
| Net cash used in financing activities | (150,000) |
| Net increase in cash | 230,000 |
| Beginning cash balance | 300,000 |
| Ending cash balance | 530,000 |
Acme's net income of $500,000 converts to $610,000 of operating cash flow, mainly because depreciation and a drop in inventory freed up cash without appearing as income. After $230,000 in net capital spending and $150,000 returned to lenders and shareholders, cash still grew by $230,000. Every figure ties: operating minus investing minus financing equals the net change, and beginning cash plus that change equals ending cash.

Free cash flow: the number investors watch
The statement is also where free cash flow (FCF) comes from — operating cash flow minus capital expenditures. For Acme, that's 610,000 − 250,000 = $360,000, the cash actually available to pay down debt, return to shareholders, or reinvest after the business funds its own asset base. FCF is often a more honest gauge of financial health than net income, because it can't be lifted by non-cash accounting choices.
Why cash flow diverges from net income
Net income and operating cash flow rarely match, and the gap is informative, not a red flag by itself. Common drivers: revenue recognition timing (sales booked on credit inflate net income before cash is collected); non-cash charges (depreciation, amortization, impairments); working capital swings (rapid growth often consumes cash even while profitable); and capital intensity (heavy capex sits in investing activities, not net income). This is also why net working capital normalization matters in diligence: reported earnings can look stable while working capital swings quietly drain or build cash behind the scenes.
| Metric | Acme (illustrative) | Apple FY2024 (real) |
|---|---|---|
| Net income | $500k | $93.7B |
| Operating cash flow | $610k | $118.3B |
| Cash above net income | +$110k | +$24.5B |
A classification nuance worth knowing
Where an item lands can shift the headline operating-cash-flow number. Under IAS 7, interest and dividends paid or received can be classified in operating or financing/investing sections at the preparer's policy choice, whereas US GAAP is more prescriptive. The same is true of capitalized versus expensed costs. These choices are technically compliant but can make two otherwise-similar companies look different, so it's worth checking the classification policy before comparing operating cash flow across filers.
What a cash flow statement can't tell you
The statement of cash flows is a lagging, period-end view — it won't show intra-month cash crunches, seasonal timing gaps, or covenant headroom on any given day. It also doesn't explain why working capital moved; that requires digging into underlying schedules, which is why analysts pair it with an EBITDA bridge or a balance sheet review rather than reading it alone.
Where MacrosLM fits
Disclosure: MacrosLM is our own product. MacrosLM can help assemble cash flow statements from source ledgers and flag reconciliation breaks between net income and the change in cash — agents like the 13-Week Cash Runway Engine, Cash Burn and Runway Analysis, and FCF Yield & Capital Allocation Scorecard work the cash side directly. It doesn't replace the judgment needed to classify unusual transactions or explain why working capital moved.
Bottom line
A cash flow statement translates accrual accounting into cash reality by splitting activity into operating, investing, and financing sections and reconciling net income to the actual change in cash. The gap between net income and operating cash flow is often the most useful number in the report. Read it alongside the income statement and balance sheet, not on its own.

Frequently asked questions
- What are the three sections of a cash flow statement?
- Operating, investing, and financing activities. Operating captures cash from core business operations; investing captures cash used to buy or sell long-term assets; financing captures cash exchanged with lenders and shareholders. Together they explain the full change in cash for the period.
- What's the difference between the direct and indirect method?
- The direct method lists actual cash receipts and payments; the indirect method starts with net income and adjusts for non-cash items and working capital changes. Both produce the same operating cash flow total, and identical investing and financing sections. Nearly all companies use the indirect method.
- Why is net income different from cash flow?
- Net income is recognized on an accrual basis; cash flow reflects actual cash movement. Non-cash charges like depreciation, plus timing gaps in receivables, inventory, and payables, mean the two figures rarely match, even for a healthy, growing business.
- Can a profitable company run out of cash?
- Yes. A company can report strong net income while receivables, inventory, or capital spending consume cash faster than operations generate it. This is why lenders and analysts look at operating cash flow, not just net income, when assessing near-term obligations.
- Does the cash flow statement replace the income statement or balance sheet?
- No. The three statements are meant to be read together — the income statement shows profitability, the balance sheet shows financial position at a point in time, and the cash flow statement shows how cash moved between two balance sheet dates. Each answers a question the others can't.
