How to Read a Cash Flow Statement

A cash flow statement shows the actual cash that came into and went out of a company over a period, sorted into three buckets: operating, investing and financing. It exists because profit on the income statement and cash in the bank are not the same thing, and the gap between them tells you a lot.

In short: the statement of cash flows reconciles a company’s starting cash balance to its ending cash balance. Operating cash flow is cash generated by the business itself. Investing cash flow is cash spent on or received from long-term assets and investments. Financing cash flow is cash raised from, or returned to, lenders and shareholders. Free cash flow, usually operating cash flow minus capital expenditures, is a common estimate of the cash a business produces that it could return to owners or reinvest.

Why profit is not cash

The income statement uses accrual accounting: it records revenue when it is earned and expenses when they are incurred, whatever happens to cash. That creates gaps in both directions.

Take Maple Widgets Inc., a hypothetical company, in its first year:

It sells $1,000,000 of widgets, but customers on 60-day terms still owe $250,000 at year-end.
It pays $600,000 for materials and wages, and also buys $150,000 of extra inventory that has not been sold yet.
It buys a $500,000 machine expected to last 10 years, so the income statement records $50,000 of depreciation.
Ignore taxes to keep it simple.

	Income statement	Cash
Sales	$1,000,000	$750,000 collected
Costs of goods sold, wages	($600,000)	($600,000) paid
Extra inventory	not an expense yet	($150,000) paid
Depreciation	($50,000)	$0 (no cash moves)
Machine purchase	not an expense	($500,000) paid
Result	$350,000 profit	($500,000) cash change

Maple Widgets reports a healthy $350,000 profit and is $500,000 poorer in cash. Nothing is wrong with the accounting. This is the normal shape of a growing business that is building inventory, extending credit, and buying equipment. It is also exactly how profitable companies run out of money.

The three sections

1. Operating activities

Most companies use the indirect method: start with net income, then adjust.

Add back non-cash expenses: depreciation and amortization, share-based compensation, impairments.
Adjust for changes in working capital: an increase in receivables or inventory uses cash (subtract it). An increase in accounts payable or deferred revenue means cash has not gone out yet, or came in early (add it).

For Maple Widgets: $350,000 net income + $50,000 depreciation minus $250,000 increase in receivables minus $150,000 increase in inventory = $0 operating cash flow. Then minus $500,000 of investing = the $500,000 drop in cash.

2. Investing activities

Cash spent on capital expenditures (capex, often labelled “payments for acquisition of property, plant and equipment”), acquisitions of other companies, and purchases of investments. Sales and maturities of investments bring cash back in.

3. Financing activities

Cash from issuing shares or borrowing, and cash used to repay debt, pay dividends, or buy back shares.

The three totals add up to the change in cash for the period, which matches the change in cash on the balance sheet.

A worked example: Apple, fiscal 2025

Here is a condensed version of Apple Inc.’s consolidated statement of cash flows for the fiscal year ended September 27, 2025, from its Form 10-K filed October 31, 2025. Figures are in millions of US dollars. This is an illustration of how to read the statement, not a view on the stock.

Operating activities	Fiscal 2025
Net income	$112,010
Depreciation and amortization	$11,698
Share-based compensation expense	$12,863
Other	($89)
Accounts receivable, net	($6,682)
Vendor non-trade receivables	($347)
Inventories	$1,400
Other current and non-current assets	($9,197)
Accounts payable	$902
Other current and non-current liabilities	($11,076)
Cash generated by operating activities	$111,482

Investing activities	Fiscal 2025
Purchases of marketable securities	($24,407)
Proceeds from maturities of marketable securities	$40,907
Proceeds from sales of marketable securities	$12,890
Payments for property, plant and equipment	($12,715)
Other	($1,480)
Cash generated by investing activities	$15,195

Financing activities	Fiscal 2025
Taxes paid on net share settlement of equity awards	($5,960)
Dividends and dividend equivalents	($15,421)
Repurchases of common stock	($90,711)
Term debt issued, net	$4,481
Term debt repaid	($10,932)
Commercial paper, net	($2,032)
Other	($111)
Cash used in financing activities	($120,686)

Net change in cash: $111,482 + $15,195 minus $120,686 = $5,991 million, which takes cash, cash equivalents and restricted cash from $29,943 million to $35,934 million.

What the numbers say

Operating cash flow roughly matched net income. $111,482 million versus $112,010 million. The non-cash add-backs (about $24.6 billion of depreciation and share-based pay) were offset by cash tied up in receivables and other working capital items. When operating cash flow runs well below net income year after year, it is worth finding out why.

Investing was a net inflow. That is unusual for most companies, and here it is because more of Apple’s investment portfolio matured or was sold than it bought. Capex itself was an outflow of $12,715 million. Always look at the lines inside the total.

Most of the cash went back to shareholders. Buybacks of $90,711 million and dividends of $15,421 million add up to $106,132 million, close to the full year’s operating cash flow.

Calculating free cash flow

The most common definition:

Free cash flow = operating cash flow minus capital expenditures

$111,482 minus $12,715 = $98,767 million for fiscal 2025. For fiscal 2024 the same 10-K shows $118,254 minus $9,447 = $108,807 million.

Free cash flow is not a GAAP or IFRS line item, so companies and data providers define it differently. Some subtract share-based compensation, arguing it is a real cost paid in shares instead of cash. On that stricter basis, Apple’s fiscal 2025 figure would be $98,767 minus $12,863 = $85,904 million. Neither version is “right”; just know which one you are looking at. Free cash flow is the main input to a discounted cash flow model, covered in how to value a stock.

Taxes: expense versus cash paid

The supplemental disclosure at the bottom of Apple’s statement shows $43,369 million of income taxes paid in cash in fiscal 2025, compared with a tax provision of $20,719 million on the income statement. The two often differ because tax expense is recorded when it is incurred, while payments follow tax-authority schedules and settlements. Apple’s fiscal 2024 income statement, for example, recorded a large one-time tax charge tied to a European Union State Aid decision, and the 10-K describes the $15.8 billion owed to Ireland as payable through the release of amounts held in escrow, after the fiscal 2024 year-end. Income taxes payable on the balance sheet fell from $26,601 million to $13,016 million over fiscal 2025. Comparing the provision with cash taxes paid over several years gives a truer picture than any single year.

Patterns worth recognising

Operating	Investing	Financing	Often seen in
+	minus	minus	Mature, profitable companies funding capex and returning cash
minus	minus	+	Young or struggling companies relying on outside money
+	minus	+	Growing companies borrowing or issuing shares to expand faster
minus	+	+ or minus	Companies selling assets to cover operating shortfalls

These are tendencies, not verdicts. A start-up with negative operating cash flow may be investing sensibly. A mature company with positive cash flow may be underinvesting.

What can go wrong

Working-capital games

Operating cash flow can be flattered for a quarter by delaying payments to suppliers, selling receivables to a third party (factoring), or cutting inventory to unusually low levels. These tricks do not repeat forever. Look at several years and at the trend in receivables and payables relative to sales.

Classification choices

Under US GAAP, interest paid is an operating cash flow and dividends paid are financing. Under IFRS, which Canadian public companies use, companies have so far been allowed to choose: interest and dividends paid can sit in operating or financing activities. That can make operating cash flow look different for otherwise similar companies. IFRS 18, effective for annual periods beginning on or after January 1, 2027, amends IAS 7 to remove most of that choice (for most companies, interest and dividends paid will go to financing), so expect comparatives to shift when companies adopt it.

Treating stock-based pay as free

Adding back share-based compensation is correct accounting, because no cash left the company. But it is still a cost to shareholders, paid through dilution. Check the share count on the income statement to see whether buybacks are reducing it or just offsetting new grants.

Capex that is really maintenance

Free cash flow assumes the capex line is what it takes to keep the business running. If a company is skimping on maintenance to boost free cash flow now, it will show up later in older equipment and higher costs.

The short version

The cash flow statement shows where cash actually came from and went. Start with operating cash flow and compare it with net income over several years. Subtract capital expenditures to estimate free cash flow, and read the financing section to see whether the company is borrowing, issuing shares, or returning cash. Profits that never turn into cash are the most important warning sign it can reveal. If you want to know where these numbers sit in the annual filing, see how to read a 10-K.
