Capital Expenditure (CapEx) Definition: Capital expenditure is the money a company spends to buy, build or upgrade long-lived assets such as factories, machinery, vehicles, buildings and software. Instead of being deducted from profit at once, the cost is recorded as an asset on the balance sheet and expensed gradually through depreciation over the asset’s useful life. A $10 million machine expected to last 10 years therefore reduces profit by about $1 million a year, while the full $10 million leaves the company’s bank account when it is paid for.
What Is Capital Expenditure?
Every business spends money in two ways. Some spending is used up within the year, such as wages, electricity and raw materials. Other spending buys something that will keep producing revenue for years, such as a warehouse, a fleet of trucks or a new chip factory. Accountants call the second kind capital expenditure.
The split matters because it changes when the cost shows up in profit. Day-to-day costs hit the income statement immediately. Capital spending is first recorded on the balance sheet as property, plant and equipment (PP&E), then written down a little each year through depreciation, the accounting charge that matches an asset’s cost to the years it is used.
This creates a gap between cash and earnings. In the year a company builds a plant, its cash falls sharply while its profit barely moves. That gap is why traders who watch earnings alone can miss how much money a business really consumes, and why CapEx sits at the centre of cash-based analysis.
How to Calculate Capital Expenditure
Most companies report CapEx directly in the investing section of the cash flow statement, often as purchases of property and equipment. When it is not shown, you can rebuild it from two balance sheets and the income statement: CapEx = PP&E at the end of the period − PP&E at the start + depreciation for the period.
Suppose net PP&E rises from $400 million to $450 million during the year while depreciation is $70 million. Depreciation alone would have shrunk the asset base to $330 million, so reaching $450 million required $120 million of new spending. This shortcut ignores asset sales, so it works best for companies that rarely dispose of equipment.
Now follow a delivery company that buys 100 trucks at $50,000 each, a $5 million purchase with a five-year useful life. In year one, $5 million leaves the bank and shows up as capital expenditure. On the income statement, depreciation is only $1 million a year for five years.
Had the company expensed the trucks at once, operating profit would have fallen by $5 million in year one and been flattered in each of the next four years. Capitalising the cost smooths profit to match the trucks’ working life. That is the purpose of the rule, but it also means a company can look profitable in a year when its cash is draining away.
Types of Capital Expenditure
Maintenance CapEx replaces worn-out assets so the business can keep producing at its present level. An airline replacing ageing engines or a retailer refitting tired stores falls into this group. Warren Buffett’s 1986 letter to Berkshire Hathaway shareholders defined owner earnings as profit plus depreciation minus this maintenance spending, arguing that it is a real cost of staying in business.
Growth CapEx expands capacity: a second factory, new stores, additional data centres. It should raise future revenue, but the payoff is uncertain and often years away.
Companies rarely split their spending between these two buckets in published accounts. Analysts often use depreciation as a rough proxy for maintenance CapEx and treat anything above it as growth.
CapEx vs. OpEx
| Capital expenditure (CapEx) | Operating expenditure (OpEx) | |
|---|---|---|
| What it buys | Assets lasting more than a year | Goods and services used up in the period |
| Examples | Factories, trucks, servers, capitalised software | Salaries, rent, utilities, marketing |
| Income statement | Spread over years through depreciation | Deducted in full immediately |
| Cash flow statement | Investing section | Operating section |
| Effect on EBITDA | None, since depreciation is added back | Reduces it directly |
That last row explains why EBITDA can flatter capital-hungry businesses. A telecom operator and a software firm may report the same EBITDA, yet the operator must spend a large share of it every year on network equipment just to stand still.
Why Is Capital Expenditure Important for Traders?
CapEx is the bridge between profit and cash. Subtracting it from operating cash flow gives free cash flow, the money available for dividends, buybacks and debt repayment. A company that must reinvest most of its operating cash just to keep its assets working has little left for shareholders, however strong its earnings look.
Spending plans also move stock prices on their own. On 27 October 2022, Meta shares fell about 25% in a single session after the company guided 2023 capital expenditure to between $34 billion and $39 billion, mostly for data centres and servers, at a time when its revenue was shrinking. Investors were not reacting to a loss; they were questioning whether the money would ever earn a return.
The main limitation is that capitalisation involves judgement. Management decides which costs count as assets and how long those assets will last, and a longer assumed life means lower annual depreciation and higher reported profit. Comparisons across companies are also distorted when one firm owns its servers and another rents cloud capacity, turning the same need into OpEx instead of CapEx.
Key Takeaways
- Capital expenditure is spending on assets that last longer than a year, recorded on the balance sheet rather than deducted from profit at once.
- Depreciation spreads the cost of CapEx over the asset’s useful life, which is why cash and reported profit diverge in years of heavy investment.
- Maintenance CapEx keeps the business running at its present size, while growth CapEx adds capacity whose returns arrive later and are uncertain.
- Free cash flow is operating cash flow minus CapEx, so capital-hungry companies can show healthy earnings and still leave little cash for shareholders.
- Assumptions about useful life and what to capitalise are management choices, and they can raise reported profit without changing the cash a business produces.
Is CapEx on the income statement?
Not directly. The purchase appears in the investing section of the cash flow statement and as an asset on the balance sheet, and only the yearly depreciation charge reaches the income statement.
Is high capital expenditure good or bad for a stock?
Neither by default. Spending that earns more than the company's cost of capital creates value, while spending on projects that never earn that return destroys it, and the market often cannot tell which until years later.
What is the difference between CapEx and depreciation?
CapEx is the cash paid for an asset when it is bought. Depreciation is the accounting charge that spreads that cost over the asset's useful life, so a company spending far more than its depreciation is usually expanding.
