capital expenditure vs revenue expenditure
/ CapEx vs RevEx /
Imagine you own a delivery truck. One day you put fuel in it and get the oil changed — routine upkeep to keep it running this month. Another day you drop in a brand-new, more powerful engine that adds years to the truck's life. Both are money spent on the truck, but they feel different: the first just keeps things going now, the second is really an investment that pays off for years. Accounting treats these two kinds of spending very differently, and the distinction is capital versus revenue expenditure.
A capital expenditure (CapEx) is money spent to acquire a long-lived asset or to improve an existing one in a way that extends its life, boosts its capacity, or upgrades its quality — these are called betterments. CapEx is capitalized: added to the asset's cost and then depreciated over time. A revenue expenditure (sometimes called an expense or an operating expense) is money spent on ordinary repairs, maintenance, and running costs that merely keep the asset working in its present condition — these are expensed in full in the period they occur. So replacing a worn-out roof to add 15 years to a building is CapEx; patching a leak is a revenue expenditure.
The distinction matters because it decides whether a cost hits this year's profit all at once or is spread over many years. Treating a routine repair as CapEx would overstate current profit and assets; treating a genuine improvement as a repair would understate them. The line is not always crisp — is a major overhaul a betterment or just a big repair? — so companies use judgment, materiality thresholds, and the test of whether the spending extends the asset's life or capacity beyond its original state. The common error is to confuse 'expensive' with 'capital': a costly repair is still a revenue expenditure if it only restores the asset, while a cheap upgrade that extends life could be capital.
A bus company spends 2,000 on routine servicing (oil, brakes, filters) and 60,000 on a new engine that adds 8 years to a bus's life. The 2,000 servicing is a revenue expenditure, expensed now. The 60,000 engine is a capital expenditure (a betterment), added to the bus's cost and depreciated over the extra years it provides.
Keep-it-running spending is expensed; make-it-better-or-last-longer spending is capitalized.
Cost size does not decide the category — purpose does. An expensive repair that merely restores an asset is still a revenue expenditure, while a modest improvement that extends its life is a capital expenditure.
