Capital expenditure in the cash flow statement appears as a cash outflow inside the investing activities section, most often on a line reading “Purchases of property, plant, and equipment” or simply “Capital expenditures.” The number is shown in parentheses because the cash left the business. It captures the full dollar amount the company spent during the period acquiring or upgrading long-lived assets such as machinery, buildings, vehicles, and technology. That is the entire hit to cash in the period the money went out, not the smaller depreciation figure that shows up on the income statement.
What the Line Includes
A purchase qualifies as CapEx when the asset is expected to deliver economic value for more than one year. A delivery truck, a new warehouse, an overhauled production line, all meet the test. The company records the purchase on the balance sheet as Property, Plant, and Equipment rather than writing it off against current revenue. Over the asset’s useful life, a portion of the original cost flows through the income statement each year as depreciation.
That treatment is what separates CapEx from operating expenses. The monthly electric bill, payroll, and a short-term software subscription are operating expenses, fully deducted in the period they occur. CapEx is capitalized: its cost sits on the balance sheet and only trickles into the income statement over time. A $600,000 piece of factory equipment might generate depreciation expense of $60,000 a year for a decade. The income statement sees a modest annual charge. The cash flow statement shows the entire $600,000 leaving the bank account in the year of purchase.
Not every asset purchase gets capitalized. The IRS lets businesses elect a de minimis safe harbor to expense smaller purchases immediately. Companies with audited financial statements can expense items costing up to $5,000 per invoice. Businesses without audited financials can expense items up to $2,500 per invoice.1Internal Revenue Service. Tangible Property Final Regulations A $2,000 laptop, for example, can be written off as an operating expense rather than capitalized, as long as the company makes the election.
Software adds a wrinkle. Licensed software bought outright generally appears in investing activities alongside equipment. Internal-use software development follows the same path once the project moves past preliminary planning. Cloud arrangements are the exception: paying for a hosted service rather than owning a license runs through operating activities, even when implementation work is significant. The notes to the financial statements are the only reliable way to tell which treatment a company used.
Where It Sits Relative to the Other Sections
The cash flow statement divides all cash movements into three sections: operating activities, investing activities, and financing activities. CapEx lives in investing, which tracks cash spent on or received from long-term assets and investments.
Because CapEx represents money flowing out, it appears as a negative figure. A line reading “Purchases of property, plant, and equipment: ($14,200,000)” means the company spent $14.2 million on fixed assets that period. Some companies use “Capital expenditures” as the label instead. The meaning is identical.
The operating activities section is where depreciation makes its appearance. Under the indirect method most companies use, net income is adjusted for non-cash items at the top of that section. Depreciation gets added back to net income because it reduced earnings on the income statement without any cash actually leaving the business. The cash already left when the asset was purchased, and that outflow was captured in investing. The two sections work together. Investing activities show the real cash cost of assets bought this period. Operating activities undo the accounting echo of assets bought in earlier periods.
The financing activities section covers something different entirely. Issuing stock, borrowing money, repaying debt, and paying dividends all appear there. Those transactions change who owns or is owed money by the company. They have nothing to do with the asset investments tracked in investing.
Asset Sales in the Same Section
The investing activities section is not exclusively negative. When a company sells a piece of equipment, land, or other fixed asset, the cash received shows up as a positive figure in the same section. If a manufacturer sells a surplus warehouse for $4 million, that inflow partially offsets the CapEx outflows reported nearby. The net figure across all investing line items reveals whether the company was a net buyer or seller of long-term assets for the period.
One accounting quirk trips up casual readers. If the company sells an asset for more than its depreciated book value, the gain appears on the income statement and inflates net income. But that gain isn’t operating cash; it came from an asset sale. So the operating activities section subtracts the gain from net income to avoid double-counting, since the actual cash already appears in investing. Losses on asset sales work the same way in reverse.
Cross-Checking the Number From the Balance Sheet
The cash flow statement hands you the CapEx figure directly, but you can also back into it using the balance sheet and income statement. This cross-check is useful when the cash flow statement lumps several investing items together or when you’re building a financial model from scratch.
The formula is straightforward. Take the current period’s net PP&E balance, subtract the prior period’s net PP&E balance, and add back depreciation expense recorded during the period.
Suppose a company reported net PP&E of $50 million at the end of last year and $60 million at the end of this year, with $5 million of depreciation expense during the current year. The math: ($60 million minus $50 million) plus $5 million equals $15 million in CapEx. Depreciation reduced the PP&E balance by $5 million during the year, so you need to add it back to see how much new spending actually occurred. Without that adjustment, the $10 million increase in PP&E would understate the true investment by the amount depreciation eroded.
Depreciation comes from the income statement or the notes. The PP&E balances come from the balance sheet. Tying the three statements together this way is a quick way to sanity-check whether reported CapEx makes sense relative to the movement in the asset base.
Reading the CapEx Number
The reason investors watch CapEx is that it’s the bridge between operating cash flow and free cash flow. Free cash flow equals cash flow from operations minus capital expenditures. What’s left tells you how much cash the business generated after paying for everything it needs to keep running and investing in its asset base. That leftover is what’s genuinely available for dividends, buybacks, debt reduction, or acquisitions.
A company can report strong net income and robust operating cash flow while still burning through cash if CapEx is high enough. This is common in telecommunications, oil and gas, and utilities, where physical infrastructure demands constant heavy spending. Asset-light businesses like software companies and consulting firms convert a much larger share of operating cash flow into free cash flow because their CapEx needs are modest.
Tracking the CapEx-to-revenue ratio over time shows whether a company is becoming more or less capital intensive. A rising ratio means each dollar of revenue costs more to support with physical assets. Utilities and energy companies routinely spend north of 10% of revenue on CapEx. Service-oriented businesses often sit in the low single digits. Comparing a company’s ratio to its industry peers and to its own history is more informative than the absolute dollar figure.
Maintenance vs. Expansion
The cash flow statement reports one CapEx number. Analysts split it into two conceptual buckets because they mean very different things about where the business is headed.
Maintenance CapEx is what the company must spend just to keep the lights on at current capacity. Replacing a worn factory roof, swapping aging delivery vehicles, upgrading safety equipment. Skip this spending and current revenue starts to erode. Expansion CapEx is everything above that baseline: building a new plant, entering a new market, adding a line for a product that doesn’t exist yet. This is spending aimed at growing the business beyond where it stands today.
The distinction matters for valuation. A company reporting $200 million in CapEx sounds like an aggressive investor in growth until you learn that $180 million of it goes to maintaining an aging asset base. That’s a mature, capital-heavy business spending most of its cash just to stand still. A company spending the same total but directing $120 million toward new capacity is making a fundamentally different bet.
Companies rarely break this out explicitly. The most common workaround is using the annual depreciation charge as a rough proxy for maintenance CapEx, on the reasoning that over time a company must spend at least as much as depreciation to replace assets as they wear out. Any CapEx materially above depreciation likely represents expansion. It’s an imperfect estimate, but the Management Discussion and Analysis section of the annual report usually gives enough context about specific projects to refine it.
Where Tax Rules Fit
Accelerated tax deductions like Section 179 expensing and 100% first-year bonus depreciation, restored permanently by the One Big Beautiful Bill Act for qualified property placed in service after January 19, 2025,2Internal Revenue Service. Treasury, IRS Issue Guidance on the Additional First Year Depreciation Deduction Amended as Part of the One Big Beautiful Bill do not change where CapEx appears on the cash flow statement. The full cash outflow still lands in investing activities in the year of purchase. What those provisions change is the tax bill, which shows up in operating activities. So when a company takes a large bonus depreciation deduction, operating cash flow rises through lower taxes even though CapEx in investing activities is unchanged.
Reading CapEx in Context
A single period’s CapEx figure in isolation says almost nothing. The number gains meaning only when stacked against depreciation, revenue, operating cash flow, and the same figures from prior years and competitors. A spike could mean the company is building aggressively for growth or replacing failing infrastructure. The Management Discussion and Analysis section is usually where management explains which one it is, and it’s worth reading before drawing conclusions from the numbers alone.
When reviewing the investing section, watch whether CapEx is climbing faster than revenue. If it is, each incremental dollar of sales is costing more to produce, a trend that compresses free cash flow and eventually pressures returns. If CapEx is falling while revenue holds steady or grows, the company may be harvesting the benefits of past investment, or it may be underinvesting in ways that catch up later. Neither trend is inherently good or bad without the context of the business’s competitive position and industry.
