Free Cash Flow

Free cash flow is the cash a business generates after spending to maintain and grow itself.

Common mix-ups

Accounting profit can look healthy while cash flow is negative; watch both.

Picture this

A delivery company reports record net income while its free cash flow turns deeply negative. The reason: it is buying hundreds of new trucks and warehouses, spending more on expansion than operations generate. The accounting profit looks great, but until the capital spending slows, the company is a net consumer of cash — it must borrow to fund its own growth. If the expansion pays off, today’s negative FCF becomes tomorrow’s profit; if not, the debt stays. That is why FCF matters more than the headline earnings number.

How to apply it

When evaluating a business, watch free cash flow trend rather than a single quarter. A company that steadily grows FCF can fund its own growth; one with negative FCF must borrow or dilute, which caps its independence.

What it means for you

It is the money a company could truly return, reinvest, or use to survive a downturn.

A quick example

Key takeaway

Free cash flow is the cash a business truly generates after keeping itself alive, and it is far harder to fake than accounting profit. A company can report record earnings while consuming cash on expansion, debt service, or inventory, and only FCF shows the difference. Watch the FCF trend rather than a single quarter, because a company that steadily grows it can fund itself, while one with negative FCF must borrow or dilute. Cash is the truth; profit is a report.
