What it means
Capital expenditure, usually shortened to capex, is spending on assets that will be used for more than one year. The cash flow statement records it when the money leaves the bank, which is quite different from the income statement, where the same spending appears slowly as depreciation over many years.
Cash flow capex is therefore the version that tells you what the business could and could not afford this year. It matters because capex is often the largest discretionary outflow a company controls.
Management can defer a factory upgrade to protect cash in a weak year, and the cash flow statement shows that choice immediately while the income statement barely moves. Investors watch the line closely because sustained underspending quietly erodes the asset base.
Analysts usually split the number into two parts. Maintenance capex is what must be spent to keep the existing business running at the same level, and growth capex is the extra spending aimed at new capacity or new markets.
Companies rarely report the split, so it is normally estimated by comparing capex with the annual depreciation charge. The most common way to use the figure is as a ratio against operating cash flow, which shows how comfortably the business funds its own investment.
A ratio of 1.0 means every cent of operating cash is consumed by capex, leaving nothing for debt repayment or dividends. Higher ratios indicate more room to manoeuvre.
Two nuances catch people out. Acquisitions of whole businesses are reported separately and are not capex, and assets obtained under a lease may appear in the financing section rather than the investing section, so a company moving from buying to leasing can show falling capex without reducing its real investment at all.
In practice
Real-world examples.
Example
A supermarket chain reports cash flow capex of $240,000,000 against depreciation of $200,000,000, so it is investing slightly above the rate at which its stores wear out. The investor relations team uses that comparison to argue the estate is being properly maintained.
Example
A haulage company cuts cash flow capex from $30,000,000 to $8,000,000 during a weak trading year by deferring fleet replacement. Cash improves in the short run, but maintenance costs on the ageing lorries rise sharply two years later, and the deferred spending returns as a much larger bill.
Example
A data centre operator shows operating cash flow of $90,000,000 and cash flow capex of $120,000,000, giving a ratio below 1.0. The gap is funded with new borrowing, which is acceptable while the new capacity is being built but would be a warning sign if it continued indefinitely.
Formula
Calculation
Cash Flow Capex = Cash Paid for Property, Plant and Equipment and Intangibles - Cash Received from Disposals
Cash Flow to Capex Ratio = Operating Cash Flow / Cash Flow Capex
A food producer paid $7,500,000 during the year for new ovens, a warehouse extension and a production planning system, and received $1,500,000 from selling two retired delivery lorries. Cash flow capex is $7,500,000 - $1,500,000 = $6,000,000.
The same company generated operating cash flow of $18,000,000. The cash flow to capex ratio is $18,000,000 / $6,000,000 = 3.0, meaning operating cash covered its investment three times over. With depreciation running at $5,000,000 a year, roughly $5,000,000 of the $6,000,000 looks like maintenance spending and about $1,000,000 looks like growth.Case study
Seen in the real world.
Harbourlight Bottling is a fictional, illustrative drinks bottler created to show how the figure behaves. For four years it reported steady profit of about $11,000,000 while cash flow capex averaged only $3,000,000 against an annual depreciation charge of $8,000,000. On paper the company looked like a strong cash generator.
A prospective buyer spotted the mismatch during due diligence. Spending less than half the depreciation charge for four years meant roughly $20,000,000 of deferred investment, and an engineering survey confirmed that two of the three bottling lines were near the end of their working lives. The apparent cash strength was really a backlog.
In this illustrative case the buyer reduced its offer by the estimated catch-up spending and made the first year of capex a condition of the deal. The lesson is simple: cash flow capex should always be read next to depreciation, because a low number can mean efficiency or it can mean a bill waiting to arrive.
Watch out
Common mistakes.
- Treating low capex as automatically good news. Spending well below depreciation for several years usually means the asset base is being run down rather than managed well.
- Including acquisitions of other companies in capex. Buying a business is a separate investing line, and mixing the two makes the underlying investment trend impossible to read.
- Using gross purchases and ignoring disposal proceeds. A company that sold $1,500,000 of old assets did not really spend the full $7,500,000 of cash on its asset base.
Questions
People also ask.
Where do I find cash flow capex in the accounts?
In the investing activities section of the cash flow statement, usually labelled as purchases of property, plant and equipment, with disposal proceeds a line or two below.
Why does capex differ from the depreciation charge?
Capex is this year's cash spending while depreciation spreads the cost of assets bought in earlier years, so the two only match when investment is steady over a long period.
Does switching from buying to leasing reduce capex?
It reduces the reported capex line, but the lease payments appear elsewhere in the statement, so the real economic investment has not fallen at all.
