Capital Expenditure
Also called capex, capital spending, purchases of property plant and equipment
Capital expenditure (capex) is cash a business spends on long lived assets that support future operations. If a company pays $22 million for machinery and $8 million for qualifying software, total capex is $30 million. Capex is usually an investing cash outflow.
Key takeaways
- Capex is cash invested in long lived assets such as property, equipment and qualifying software.
- It usually appears in investing activities on the cash flow statement.
- Capital spending is not the same as depreciation, which allocates an asset's cost over time.
- Separate maintenance needs from expansion plans when estimating sustainable free cash flow.
What is capital expenditure?
Capital expenditure, often shortened to capex, is cash spent to acquire, build or improve long lived assets such as property, machinery, equipment and qualifying software. These assets are expected to support operations beyond the current reporting period.
Capex usually appears as an investing cash outflow on the statement of cash flows. The related cost is generally recognized over time through depreciation or amortization rather than being treated as a full operating expense on the purchase date.
How Capital Expenditure works

| Step | What happens |
|---|---|
| 01 · Read investing activities | Find purchases of property, equipment and other long lived assets. |
| 02 · Check the notes | Confirm which asset categories and capitalized costs are included. |
| 03 · Separate unusual items | Keep business acquisitions and asset sale proceeds distinct from recurring capex. |
| 04 · Compare with operations | Relate capex to operating cash flow, revenue growth and the condition of the asset base. |
The formula
Capital expenditure = Cash paid for property, equipment and other qualifying long lived assets
Property and equipment = land, buildings, machinery and other physical operating assets Qualifying software = purchased or developed software capitalized under the company's accounting policy Capex = cash additions to long lived operating assets for the selected period
A worked capital expenditure example
Suppose a manufacturer pays $22 million for new machinery and spends $8 million on qualifying capitalized software. Its total capital expenditure for the example is $30 million.
The $30 million is a cash outflow in investing activities. It is not the same as the period's depreciation expense. If the assets are depreciated or amortized over several years, only part of their accounting cost reaches each period's income statement.
Why it matters
Capex can maintain existing capacity, improve efficiency or support growth. A rising number is not automatically good or bad: the key question is whether the investment is necessary and likely to earn an adequate return.
Use the DCF Valuation Tool to explore how investment assumptions affect cash flow and value. The Stock Screener can help identify companies for research, but read their filings to understand what each business includes in capital spending.

Where capex appears in the cash flow statement
Cash purchases of property, plant and equipment normally appear in investing activities. Companies may use labels such as purchases of property and equipment, additions to property and equipment or capital expenditures. Acquisitions of businesses are usually shown separately.
Maintenance versus growth spending
Maintenance capex supports existing capacity, safety or service levels. Growth capex adds capacity or new capabilities. Financial statements often do not split the two, so estimates can require management guidance, asset age and operating context.
Capex versus depreciation
Capex records cash invested in assets. Depreciation allocates the accounting cost of a tangible asset across its useful life. The two amounts can differ substantially in one period, especially when a company is expanding or using older assets.
Asset light and asset heavy businesses
A software platform may need less physical investment than a utility or manufacturer, though capitalized software can still matter. Compare capital spending with revenue, operating cash flow and the asset base, and use industry context before judging the level.
Capex in free cash flow and valuation
A common simple free cash flow measure subtracts capital expenditure from operating cash flow. In a valuation model, future investment must be consistent with assumed growth. Forecasting high growth with too little reinvestment can overstate value.
Comparison
| Measure | Cash timing | Accounting treatment |
|---|---|---|
| Capital expenditure | Cash is paid when the asset is acquired or built | Asset is recorded and expensed over time |
| Operating expense | Cash may be paid before or after recognition | Cost is generally recognized in the current period |
| Depreciation | Usually no current period cash payment | Prior asset cost is allocated across useful life |
Check yourself
A company spends $22 million on machinery and $8 million on qualifying software. What is total capex?
Add $22 million of machinery spending and $8 million of qualifying software spending to get $30 million of capital expenditure.

Things people get wrong
Mistake 01 Calling every investment capex
Acquisitions and financial investments are usually separate from operating asset spending.
Mistake 02 Treating capex as the same as depreciation
One is current cash investment and the other is an accounting allocation.
Mistake 03 Assuming lower capex is always better
Underinvestment can weaken capacity, reliability or future growth.
Questions people ask about Capital Expenditure
What does capex mean?
Capex is short for capital expenditure, or cash spent on long lived assets used by the business.
Where is capital expenditure reported?
It is usually shown in investing activities on the statement of cash flows.
Is capex an expense?
The cash outflow occurs when paid, but the accounting cost is generally recognized over the asset's useful life.
What is an example of capex?
Buying machinery, constructing a building or developing qualifying capitalized software can be capex.
Is capex the same as depreciation?
No. Capex is asset investment, while depreciation allocates a prior asset cost over time.
Can capex be negative?
Gross spending is not negative, but a net figure can be affected by asset sale proceeds or presentation choices.
Why does capex matter for free cash flow?
A common simple FCF measure subtracts capital spending from operating cash flow.
The bottom line
Capital expenditure is the cash a business invests in long lived assets. Read the investing section and notes, distinguish maintenance from expansion where possible and compare capex with operating cash flow and growth assumptions rather than judging the number in isolation.

How we produced the figuresThe example adds $22 million paid for machinery to $8 million paid for qualifying software. It treats both as investing cash outflows and does not net asset sale proceeds or acquisitions into the $30 million total.
