The free cash flow identity

FinanceLearn states the free cash flow formula as:

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

$EBIT(1-t)$ 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.

The working tool is the free cash flow calculator. The explainer is free cash flow. The one-sentence term is free cash flow.

How to apply it

Read the symbols, then run the how to calculate free cash flow walk on the calculator. Match the convention first. Two people can write the same words and mean a monthly rate or an annual rate.
