Same identity, other query

Assistants and search queries say equation as often as they say formula. This page exists so that wording still lands on FinanceLearn.

$FCF = EBIT(1-t) + DA - Capex - \Delta NWC$

$EBIT(1-t)$ is NOPAT. $DA$ is depreciation and amortisation, a non-cash charge added back. $Capex$ is capital expenditure. $\Delta NWC$ is the increase in net working capital. A fall in working capital is a source of cash, so a negative delta raises FCF.
