TL;DR: Capital expenditure, or CapEx, is cash spent on long term assets that will be used for more than one year. Illustrative example only: a company ends the year with property, plant, and equipment of $850,000, began with $700,000, and recorded depreciation of $90,000. Its CapEx is $240,000, since $850,000 minus $700,000 plus $90,000 equals $240,000. That derivation assumes no asset sales, write downs, or acquisitions in the period. CapEx is an investing cash outflow, not an expense on the income statement in the year it is spent.
Key Takeaways
- The worked example in this draft is fully illustrative. Its arithmetic is recorded in Sources and method below and was recomputed for this draft.
- Definitions here follow standard filing usage. Where providers or filings use a different definition, the draft says so and tells you to check which one a source is using.

Derive CapEx from the balance sheet in full
All figures in this section are illustrative. Companies report CapEx directly on the cash flow statement, usually as purchases of property, plant, and equipment, but you can also derive it from the balance sheet, which is a useful cross check. Property, plant, and equipment, net of depreciation, rose from $700,000 to $850,000 during the year, an increase of $150,000. Depreciation for the year was $90,000, which reduced the book value of those assets without any cash leaving.
For the net figure to rise by $150,000 while depreciation pulled it down by $90,000, the company must have added $240,000 of new assets. That is the CapEx: $850,000 minus $700,000 plus $90,000 equals $240,000. This derivation assumes the figures are net property, plant, and equipment, that the $90,000 of depreciation all relates to it, that additions were paid in cash, and that there were no asset sales, write downs, revaluations, currency effects, or acquisitions in the period. Where those exist, the cash flow statement figure is the cleaner source, and the balance sheet check in how to read a balance sheet shows where each item sits. CapEx is also the spending subtracted from operating cash flow inside the free cash flow that price to free cash flow explained prices.
How is CapEx different from an operating expense?
An operating expense, such as rent, wages, or a repair that merely maintains an asset, is charged against profit in the period it occurs. CapEx is treated differently. The cost is recorded as an asset first, then charged gradually through depreciation over the asset useful life. That is why a company can spend heavily on CapEx in a year when reported profit barely moves, and why the cash flow statement, covered in how to read a cash flow statement, is essential for seeing the real cash cost.
Analysts often split CapEx into maintenance CapEx, which keeps existing capacity running, and growth CapEx, which expands it. Companies rarely report that split directly, so treat any estimate of it as an estimate. The distinction matters because free cash flow, in what is free cash flow, subtracts all CapEx. Judging whether that subtraction is mostly upkeep or mostly expansion changes how you read the result.
What CapEx tells an investor
Compare CapEx with depreciation over several years. CapEx persistently below depreciation can mean the asset base is being run down, which may flatter near term cash flow while storing up a catch up bill. CapEx far above depreciation may indicate expansion, though replacement cost inflation and lumpy replacement timing can produce the same gap, and expansion is only good news if the new assets earn adequate returns, a question return on invested capital explained helps you test. Also compare CapEx with operating cash flow. A business funding large CapEx entirely from its own operations is in a different position from one borrowing to build.
CapEx intensity varies enormously by industry, so compare a company with its own history and its direct peers, not with businesses in unrelated sectors.
