Frequently asked questions

What is free cash flow?

FCF is operating cash flow minus capital expenditures. It is the cash a company can return to investors or reinvest after maintaining its asset base.

Why does FCF matter?

Free cash flow shows real cash generation, not just accounting profit. Strong, growing FCF gives a business room to pay dividends, cut debt or fund growth.
