Capital expenditure, or CapEx, is spending on long-lived assets that support operations over multiple periods. Examples include equipment, facilities, infrastructure, capitalized software, and major upgrades.
CapEx matters when comparing EBITDA margin to cash flow. EBITDA excludes depreciation and amortization, but asset-heavy companies often need ongoing CapEx to maintain revenue.
Use CapEx with free cash flow, EBITDA margin, and ROIC. Related calculator: CapEx Calculator.
