What the cash flow statement shows
Having the cash flow statement explained properly starts with one idea: profit and cash are different things. The income statement records revenue when it is earned and expenses when they are incurred, so a profitable company can still run short of money if customers pay slowly or it buys a lot of equipment.
The cash flow statement fixes that blind spot. It starts from the opening cash balance, lists every inflow and outflow in three groups, and ends at the closing cash balance that appears on the balance sheet. If your statement does not land on that figure, something is missing.
Instructors set this topic because it tests whether you understand how the other two statements connect. Almost every line comes from either a balance sheet change or an income statement item that did not involve cash.
The three sections: operating, investing and financing
| Section | What belongs here | Typical inflows | Typical outflows |
|---|---|---|---|
| Operating activities | Cash from the main trading activity of the business | Receipts from customers | Payments to suppliers and employees, interest and tax paid (under US GAAP) |
| Investing activities | Buying and selling long-term assets and investments | Proceeds from selling equipment or investments | Purchases of property, plant, equipment and securities |
| Financing activities | Dealings with the owners and lenders who fund the business | New share issues, new loans | Loan repayments, dividends paid, share buybacks |
A useful test for any item is to ask who the other party is. Customers and suppliers point to operating, sellers of long-term assets point to investing, and shareholders or lenders point to financing.
US GAAP and IFRS differ on a few items
Under US GAAP, interest paid, interest received and dividends received are operating cash flows, and dividends paid are financing. IAS 7 has allowed companies a choice for these items. IFRS 18, which applies to reporting periods beginning on or after 1 January 2027, removes most of that choice for ordinary trading companies. Follow whichever framework your course specifies and say which one you used.
The indirect method, step by step
Most published statements and most assignments use the indirect method for the operating section. You start with net income and adjust it back to cash in three moves.
- Add back non-cash expenses. Depreciation and amortization reduced profit without any cash leaving the business.
- Remove gains and add back losses on asset sales. The full sale proceeds will appear in investing, so the gain or loss must come out of operating to avoid counting it twice.
- Adjust for working capital changes. An increase in a current asset (receivables, inventory) uses cash, so subtract it. An increase in a current liability (payables, accrued wages) means cash has not yet been paid, so add it. Decreases work the other way.
Students most often lose marks on the third step by getting a sign backwards. The rule of thumb: assets move opposite to cash, liabilities move with cash.
A worked example: Harbor Supply Co.
Harbor Supply Co. is a hypothetical wholesaler. For the year it reports net income of $84,000 after depreciation of $30,000. During the year it sold equipment that had cost $40,000 with accumulated depreciation of $25,000, so its book value was $15,000. It received $11,000, a loss of $4,000.
Balance sheet movements: receivables rose $18,000, inventory fell $6,000, payables rose $9,000 and accrued wages fell $2,000. It bought new equipment for $95,000, took out a $50,000 loan, repaid $20,000 of an older loan and paid dividends of $35,000. Opening cash was $41,000.
Statement of cash flows, indirect method (hypothetical)
| Line | Working | Amount |
|---|---|---|
| Net income | From the income statement | $84,000 |
| Add: depreciation | Non-cash expense | $30,000 |
| Add: loss on sale of equipment | $15,000 book value less $11,000 proceeds | $4,000 |
| Less: increase in receivables | Asset up, cash down | ($18,000) |
| Add: decrease in inventory | Asset down, cash up | $6,000 |
| Add: increase in payables | Liability up, cash up | $9,000 |
| Less: decrease in accrued wages | Liability down, cash down | ($2,000) |
| Net cash from operating activities | 84 + 30 + 4 - 18 + 6 + 9 - 2 (thousands) | $113,000 |
| Purchase of equipment | ($95,000) | |
| Proceeds from sale of equipment | $11,000 | |
| Net cash used in investing activities | -95 + 11 | ($84,000) |
| New loan | $50,000 | |
| Loan repayment | ($20,000) | |
| Dividends paid | ($35,000) | |
| Net cash used in financing activities | 50 - 20 - 35 | ($5,000) |
| Net increase in cash | 113 - 84 - 5 | $24,000 |
| Opening cash | $41,000 | |
| Closing cash | 41 + 24 | $65,000 |
The closing figure of $65,000 must match the cash line on the year-end balance sheet. If it does not, recheck each balance sheet change before anything else.
The direct method with the same numbers
The direct method lists actual cash receipts and payments instead of adjusting profit. Standard setters encourage it, but few companies use it, so assignments usually ask for it only as a comparison. To build it you need the income statement detail.
Harbor's income statement shows sales of $620,000, cost of goods sold of $372,000, cash-type operating expenses (including wages) of $126,000, depreciation of $30,000, the $4,000 loss and interest expense of $4,000, which was paid in full. Check: 620 - 372 - 126 - 30 - 4 - 4 = 84, matching net income.
| Cash flow | Working | Amount |
|---|---|---|
| Received from customers | Sales $620,000 less increase in receivables $18,000 | $602,000 |
| Paid to suppliers | Purchases = $372,000 COGS - $6,000 inventory decrease = $366,000; less $9,000 payables increase | ($357,000) |
| Paid for operating expenses | $126,000 plus the $2,000 reduction in accrued wages | ($128,000) |
| Interest paid | Expense fully paid in the year | ($4,000) |
| Net cash from operating activities | 602 - 357 - 128 - 4 | $113,000 |
Both methods give $113,000. Depreciation and the loss never appear in the direct method, because neither involved cash. Seeing the two totals agree is the best way to prove to yourself, and your marker, that the adjustments were right.

Order your cash flow statement helpHow to interpret a cash flow statement
Many assignments go beyond preparation and ask what the statement says about the business. Look at the pattern of the three totals first, then at a few measures.
| Pattern (operating / investing / financing) | Usual reading |
|---|---|
| Positive / negative / negative | A healthy, mature business funding investment and paying owners from its own trading |
| Positive / negative / positive | Growing; borrowing or raising equity to invest beyond what operations generate |
| Negative / negative / positive | Early stage or struggling; outside money is keeping the business going |
| Negative / positive / any | Possibly selling assets to survive; worth investigating |
For Harbor: free cash flow, defined here as operating cash flow less capital spending, is $113,000 - $95,000 = $18,000. Operating cash flow is 1.35 times net income ($113,000 / $84,000), which suggests profit is backed by cash. If current liabilities at year end were $90,000, the operating cash flow ratio would be $113,000 / $90,000 = 1.26.
The one warning sign is receivables growing by $18,000. If sales did not grow at a similar rate, customers may be paying more slowly, which is worth a sentence in your analysis.
Common mistakes in cash flow assignments
- Reversing working capital signs An increase in receivables is subtracted, not added.
- Counting the asset sale twice Remove the gain or loss in operating; show full proceeds in investing.
- Using the asset cost instead of the cash received Investing shows the cash proceeds, not the original cost or book value.
- Putting dividends paid in operating Under US GAAP they are financing.
- Netting new loans against repayments Show borrowing and repayment as separate lines.
- Not reconciling to the balance sheet Closing cash must equal the balance sheet figure.
- Forgetting non-cash transactions Buying equipment with a loan or with shares is disclosed in a note, not in the statement.
Building the statement from two balance sheets
Exam questions often give you only an opening and closing balance sheet plus an income statement. Work through it in a fixed order and nothing gets missed.
- List every balance sheet line with its change. Put the opening figure, the closing figure and the difference side by side.
- Tick each change off as you use it. Current assets and liabilities go to operating; long-term assets to investing; loans, share capital and retained earnings to financing.
- Reconstruct the long-term asset accounts. The change in equipment is usually a mix of purchases, disposals and depreciation, so it cannot be used as a single number.
- Explain retained earnings. Opening balance plus net income minus dividends should give the closing balance; the gap is often the dividend figure you need.
Reconstructing the equipment accounts (hypothetical)
| Account | Opening | Add | Less | Closing |
|---|---|---|---|---|
| Equipment at cost | $400,000 | Purchases $95,000 | Disposal at cost $40,000 | $455,000 |
| Accumulated depreciation | $150,000 | Charge for year $30,000 | On disposal $25,000 | $155,000 |
Check the cost line: 400 + 95 - 40 = 455. Check the depreciation line: 150 + 30 - 25 = 155. If a question gives you the two closing figures and the disposal details, the purchase figure is whatever balances the first row.
Leaving one balance sheet change unticked is the most common reason a statement fails to reconcile, so the ticking step is worth the extra minute.
