Capital Expenditure (CapEx): Definition, Formula & Ratio Analysis
Capital expenditure is the cash a company must deploy into physical assets just to stay in business — and to grow. It is the single largest lever separating companies with high free cash flow from those that generate accounting profits but little actual cash. CapEx intensity varies enormously across sectors: a utility reinvests 15–25% of revenue into physical infrastructure while a software company reinvests 1–3%. Understanding how much CapEx a business requires — and whether that spending is maintenance or growth — is fundamental to any DCF valuation or FCF yield analysis.
Capital expenditure (CapEx) is cash spent to acquire, upgrade, or maintain long-term physical assets — it reduces free cash flow directly. CapEx / Revenue measures how asset-intensive a business is. Apple FY2024: $9.4B CapEx on $391B revenue = 2.4% — exceptionally low for a hardware company.
How to Find CapEx in Financial Statements
CapEx appears in two places on a 10-K: directly on the cash flow statement as a labeled line item, and indirectly on the balance sheet through changes in PP&E. The cash flow statement is always the easier and more reliable source.
| Method | Formula | When to use |
|---|---|---|
| Direct (cash flow) | Read “Purchases of PP&E” | Always preferred — exact figure, no calculation required |
| Indirect (balance sheet) | ΔPP&E + Depreciation | When cash flow statement is not available or you want to cross-check |
The indirect formula works because gross PP&E rises when assets are purchased and falls through depreciation. Adding back depreciation isolates the net new spending. Differences between the two methods usually reflect asset disposals or acquisitions.
Maintenance CapEx vs Growth CapEx
The most analytically important distinction is between spending that simply sustains current output and spending that expands it. Companies rarely break this out in their filings — but the distinction drives valuation.
Maintenance CapEx
Spending required to preserve existing productive capacity — replacing worn equipment, repairing facilities, refreshing fleet. This is a recurring cost of doing business; it should be deducted when calculating true owner earnings or free cash flow. A business with high maintenance CapEx has less financial flexibility than its operating income implies.
Growth CapEx
Discretionary spending to expand capacity and generate future revenue — a new semiconductor fab, an additional distribution center, a new data center cluster. Growth CapEx is an investment in future cash flows; its value depends on the returns it earns relative to the cost of capital. High growth CapEx compresses near-term FCF but creates value if ROIC exceeds WACC.
Apple FY2024 — CapEx Worked Example
Apple (AAPL) FY2024 (ended September 2024) illustrates why CapEx intensity matters for valuation. Apple's 2.4% CapEx/Revenue ratio is strikingly low for a company that ships physical hardware — the result of its fabless manufacturing model where TSMC and other contract manufacturers own the production assets.
- Revenue
- $391B — iPhone, Services, Mac, iPad, and Wearables combined
- Operating Cash Flow
- $118B — exceptionally high; reflects 24% net margin + D&A add-back
- Capital Expenditures
- $9.4B — primarily retail stores, corporate facilities, and data infrastructure; no fabs
- CapEx / Revenue
- 2.4% — asset-light despite being a hardware company
- Free Cash Flow (OCF − CapEx)
- $108.8B — one of the largest FCF pools of any public company
Apple's low CapEx intensity is a structural advantage: it earns hardware economics while carrying software-like reinvestment requirements. Compare this to Intel, which runs CapEx/Revenue of 25–35% because it owns its own fabs.
CapEx / Revenue by Sector
CapEx intensity is a structural feature of a business model, not a management choice. Asset-heavy sectors must constantly reinvest to maintain their physical infrastructure. Asset-light sectors generate cash with minimal physical reinvestment — which is why software companies trade at higher multiples on the same earnings.
| Sector | Typical CapEx / Revenue |
|---|---|
| Utilities | 15–25% |
| Telecom | 12–18% |
| Energy (Integrated) | 8–15% |
| Semiconductors (IDM) | 15–25% |
| Industrials / Manufacturing | 4–8% |
| Consumer Staples | 3–6% |
| Technology Hardware (fabless) | 2–5% |
| Healthcare / Pharma | 3–7% |
| Retail | 2–5% |
| Software / SaaS | 1–3% |
| Financial Services | 1–2% |

Why CapEx Matters to Investors
CapEx directly determines free cash flow. FCF = Operating Cash Flow − CapEx. A company with $1B operating cash flow but $900M in CapEx generates only $100M of FCF — very different from a company with $500M operating cash flow and $50M in CapEx, which generates $450M FCF. Accounting earnings can look similar; FCF tells the truth about what cash is actually available to shareholders.
CapEx intensity affects valuation multiples. Investors pay premium EV/EBITDA and P/E multiples for asset-light businesses precisely because their earnings convert to cash at a high rate. A 20x P/E on a software company with 1% CapEx intensity is a fundamentally different bet than 20x on a utility with 20% CapEx intensity — even if both have identical GAAP earnings. See the DCF calculator to model how different CapEx assumptions change intrinsic value.
Return on invested capital requires CapEx context. High CapEx alone is not the problem — high CapEx that earns returns below the cost of capital is. A company reinvesting heavily into projects that earn 8% ROIC when its WACC is 10% is destroying value with every dollar spent. Conversely, a company earning 25% ROIC on growth CapEx is compounding value rapidly. The ROIC guide covers how to evaluate whether CapEx spending is creating or destroying shareholder value.
Watch for capitalizing operating expenses. Companies under pressure sometimes reclassify recurring operating costs as CapEx to boost reported earnings (the cost hits depreciation over several years instead of hitting this year's income statement all at once). A sudden unexplained jump in CapEx alongside rising goodwill or intangible assets warrants scrutiny.
Frequently Asked Questions
What is capital expenditure (CapEx)?
CapEx is cash a company spends to acquire, upgrade, or maintain long-term physical assets — property, plant, and equipment (PP&E). Unlike operating expenses, CapEx is capitalized on the balance sheet and depreciated over time. It appears as a cash outflow in the investing section of the statement of cash flows.
How do you calculate CapEx from financial statements?
Read it directly from the cash flow statement as “Purchases of property and equipment.” If you need to back-calculate, use: CapEx = Ending PP&E − Beginning PP&E + Depreciation & Amortization. The cash flow statement figure is always the more reliable source.
What is the difference between maintenance CapEx and growth CapEx?
Maintenance CapEx sustains existing capacity (replacing aging equipment). Growth CapEx expands capacity to generate future revenue (building a new facility). The distinction matters for valuation: maintenance CapEx is a recurring cost that permanently reduces owner earnings; growth CapEx is an investment whose value depends on the returns it earns relative to the cost of capital.
