Free cash flow (FCF): definition, formula and Apple example
What free cash flow is, how to calculate it, how to read FCF margin and FCF per share, and the stock-compensation debate, with Apple’s fiscal 2025 numbers.
On this page
Free cash flow (FCF) is the cash a business produces from its operations after paying for the equipment, buildings and other long-lived assets it needs to keep running and growing. It is the money left over that could be paid to shareholders, used to repay debt, spent on acquisitions or simply kept. Investors like it because it is harder to dress up than net income: it counts cash that actually moved.
There is no single official definition. FCF is not a US GAAP line item, so companies and data providers calculate it slightly differently. The most common version is simple: cash from operating activities minus capital expenditures, both taken from the cash flow statement.
This page shows how to compute FCF from Apple's fiscal 2025 filing, how to turn it into a margin and a per-share figure, why it fell in fiscal 2025 while profit rose, and the debates about stock-based compensation and maintenance capex that change what "free" really means.
The formula
Cash from operating activities (CFO, or operating cash flow) starts with net income, adds back non-cash expenses such as depreciation and stock compensation, and adjusts for changes in working capital. Capital expenditures (capex) are payments for property, plant and equipment. Apple labels its capex line "payments for acquisition of property, plant and equipment."
Apple's free cash flow, fiscal 2023 to 2025
A margin near 24% means that out of every $100 of sales, about $24 was left as free cash after running the business and investing in it. For a large hardware company that is unusually high; as a rough rule of thumb, many mature industrial and consumer companies land in the single digits to low teens, while asset-light software firms can be higher. Treat that only as orientation, not a benchmark.
Why FCF fell in fiscal 2025
Net income rose 19.5%, from $93,736 million to $112,010 million (helped by the absence of fiscal 2024's one-time $10.2 billion EU State Aid tax charge). Free cash flow went the other way, down $10,040 million. The cash flow statement shows two causes:
- Cash from operations fell $6,772 million (118,254 → 111,482). Changes in operating assets and liabilities took $25,000 million of cash in fiscal 2025 after adding $3,651 million in fiscal 2024. The largest items were other current and non-current liabilities (−11,076 versus +15,552 a year earlier), other assets (−9,197) and accounts receivable (−6,682).
- Capex rose $3,268 million (9,447 → 12,715).
Working capital swings like these often reverse, because they depend on the timing of supplier payments, tax payments and quarter-end sales. One filed fact is worth noting: Apple's cash taxes paid were $43,369 million in fiscal 2025 versus $26,102 million a year earlier. The filing does not attribute the liabilities swing line by line, though, so this page doesn't either. The lesson is to look at FCF over several years rather than react to one.
FCF versus net income
Net income is an accounting measure built on accruals; FCF is cash. Over a long period they should be roughly similar for a stable business. Big, persistent gaps tell you something:
- FCF well below net income can mean heavy investment (capex above depreciation), growing receivables or inventory, or revenue recognized before cash arrives.
- FCF well above net income can mean large non-cash charges (write-downs, amortization of acquired intangibles), stock compensation, customers paying in advance, or capex below depreciation as a company under-invests.
Apple's ratio was 0.88 in fiscal 2025, 1.16 in fiscal 2024 (108,807 ÷ 93,736) and 1.03 in fiscal 2023 (99,584 ÷ 96,995). The Quality of earnings: accruals, cash conversion and red flags page builds on that comparison.
The stock-based compensation debate
Cash from operations adds back stock-based compensation (SBC) because it is a non-cash expense. Apple added back $12,863 million in fiscal 2025, equal to 11.5% of net income. Critics argue this flatters FCF: employees are paid in stock instead of cash, the cost shows up as dilution, and companies often spend real cash buying back shares to offset it.
Neither number is "right." Subtracting SBC treats it like a cash wage; leaving it in and watching the diluted share count instead reaches a similar answer by another route. What matters is consistency: compare companies on the same basis, and be wary of SBC-heavy firms that quote only the friendlier FCF.
Maintenance versus growth capex
Capex covers two different things. Maintenance capex replaces worn-out assets to keep current output running. Growth capex expands capacity or enters new markets. In theory only maintenance capex should come out of "free" cash, since growth spending is optional. Companies almost never report the split, so analysts estimate it, often using depreciation as a rough proxy for maintenance.
For Apple in fiscal 2025, capex of $12,715 million was 1.09× depreciation and amortization of $11,698 million. Capex close to D&A suggests spending broadly in line with replacing assets, with some growth on top. A company whose capex runs far below D&A for years may be boosting FCF by starving the business.
Levered and unlevered free cash flow
The CFO-minus-capex figure above is close to levered free cash flow: it is after interest payments, because interest flows through operating cash flow under US GAAP. It is the cash available to shareholders.
Unlevered free cash flow (free cash flow to the firm) estimates the cash available to all capital providers, lenders and shareholders together, before interest. Analysts typically build it from operating profit after tax, add back D&A, subtract capex and the change in working capital. Unlevered FCF is the usual input to a Discounted cash flow (DCF): a step-by-step valuation on Apple model of enterprise value; levered FCF fits equity-level measures like FCF yield. Definitions vary by firm, so check how a data source builds the figure.
Free cash flow next to its neighbors
| Measure | Apple fiscal 2025 | What it counts | Main blind spot |
|---|---|---|---|
| Net income | $112,010M | Accrual profit after all expenses and tax | Ignores capex and working capital |
| EBITDA | $144,748M | Operating profit before D&A | Ignores capex, tax, working capital |
| Cash from operations | $111,482M | Cash from the business, after interest and tax | Ignores capex |
| Free cash flow | $98,767M | CFO minus capex | SBC still added back |
| FCF − SBC | $85,904M | FCF treating stock pay like cash | Can double count with dilution |
The EBITDA: what it means, how to calculate it and its limits page explains why EBITDA sits so far above FCF. Dividing FCF by market capitalization gives the Free cash flow yield: formula, benchmarks and shareholder yield, 2.62% for Apple at the September 26, 2025 close.
How Finabase does it
The Cash flow card on the Financials tab lists operating cash flow, capex and share-based compensation for each annual or quarterly period, so you can compute FCF and FCF − SBC yourself; Finabase does not show a separate FCF line in the statements. The Valuation tab charts ten fiscal years of P/FCF and FCF Yield, plus year-over-year Free Cash Flow growth as bars, using FMP data. The Key statistics on the AAPL summary page include a trailing Free cash flow figure passed through from the data provider, which may be built differently from the 10-K calculation here.
Frequently asked questions
How do you calculate free cash flow?
Subtract capital expenditures from cash from operating activities, both from the cash flow statement. For Apple's fiscal 2025, $111,482 million minus $12,715 million gives $98,767 million.
Is free cash flow better than net income?
Free cash flow is harder to manipulate because it tracks cash, but it is lumpier, since working capital and capex swing from year to year. Most analysts read both and look into large, lasting gaps between them.
Can free cash flow be negative?
Yes. A company investing heavily, building inventory or losing money can spend more than its operations bring in. Negative FCF is normal for young growth companies and a warning sign for mature ones that keep reporting profits.
Why did Apple's free cash flow drop in fiscal 2025?
Operating cash flow fell $6,772 million as working capital absorbed $25,000 million of cash, and capital expenditures rose $3,268 million. Net income rose in the same year, which shows how the two measures can diverge.
Summary
Free cash flow is cash from operations minus capital expenditures: the cash a business generates after paying to keep and grow its asset base. Apple produced $98,767 million in fiscal 2025, a 23.7% margin and $6.58 per diluted share, down from $108,807 million in fiscal 2024 as working capital absorbed cash and capex rose. Read FCF over several years, compare it with net income, decide whether to subtract stock compensation, and remember that capex mixes maintenance with growth.
