What is Capital Expenditure?
Short answer: Capital expenditure, or CapEx, is cash or accrued spending to acquire, construct or improve a long-term asset when the applicable accounting policy requires capitalisation. It differs from operating expenditure, which is recognised as expense as the related benefit is consumed.
Typical items include property, equipment and qualifying development or implementation costs. Payment size does not decide the treatment. Recognition depends on the applicable standard, expected benefits, control, reliable measurement and the company's consistent capitalisation policy. The capitalised amount enters the balance sheet, then is depreciated or amortised over its useful life and tested for impairment where required. Cash may be paid before, during or after recognition. Maintenance and growth CapEx are useful analytical labels, but they are not universal accounting categories.
How it works
Approve projects against a business case and record purchase orders, invoices and asset identifiers. Determine which directly attributable costs bring the asset to the location and condition needed for use. Expense training, inefficiency and other amounts when the accounting rules require it. Set the in-service date, useful life, residual value, depreciation method and component treatment. Reconcile the fixed-asset register to the general ledger and cash flow statement. For planning, separate committed from discretionary projects, map payment dates and distinguish replacement capacity from expansion using engineering or operating evidence.
Straight-line depreciation = (capitalised cost - residual value) / useful life
Example
A machine has a purchase price of 500, qualifying installation cost of 40 and staff training cost of 20. If the applicable policy capitalises the purchase and installation but expenses training, initial asset cost is 540 and current training expense is 20. With a five-year useful life, no residual value and straight-line depreciation, annual depreciation is 540 / 5 = 108. If all amounts are paid immediately, total cash outflow is 560 even though only 20 is current expense and 540 is initially recorded as an asset.
Why it matters
Founders and CFOs use CapEx plans to balance capacity, maintenance and liquidity. Boards approve major investments and monitor benefits against the business case. Lenders assess whether required spending leaves enough cash for debt service and may define permitted CapEx. Buyers examine whether historical investment was deferred and what must be spent after completion. Sellers support asset condition and forecast requirements with records. Investors incorporate CapEx into free cash flow, return analysis and valuation rather than relying on EBITDA alone.
Capitalisation can increase current profit without increasing cash, so aggressive policies can overstate performance. Useful lives, residual values and impairment involve judgement. Tax depreciation and allowances often differ from book accounting. Leases, software, development, borrowing costs and asset retirement obligations have separate requirements. Maintenance versus growth classification does not override IFRS or US GAAP recognition. Accountants and tax advisers should confirm the treatment, while lenders and transaction parties must follow their signed definitions.
