When you buy a share of a company, you become a part-owner. But as an owner, can you spend the "net profit" shown on the profit and loss statement? Not really. Net profit is an accounting figure. It includes non-cash items and ignores the real cash spent on keeping the business running. To find out how much actual cash is left for you, the owner, you need to look at Free Cash Flow (FCF).

The Simple Formula for Free Cash Flow

Free Cash Flow is the money a company has left over after paying for its daily operating expenses and investing in its physical assets (like machinery, buildings, or technology). To calculate it, you only need two numbers from the Cash Flow Statement: Cash Flow from Operations (CFO) and Capital Expenditure (Capex). CFO is the cash generated from selling goods or services. Capex is the cash spent to maintain or buy new physical assets.

A Worked Example: Vibrant Paints

Let us calculate the Free Cash Flow for an imaginary company, Vibrant Paints. Suppose you open its financial reports and find the following figures for the financial year:

The Capex Trap: When is Negative FCF Okay?

Sometimes, you will see a company with negative Free Cash Flow. This happens when Capex is larger than CFO. Is this always a bad sign? Not necessarily. It depends entirely on where the company is in its life cycle.

Imagine a young, high-growth company building its very first factories. It needs to spend heavily on land, buildings, and machinery (high Capex) to grow. During this phase, its CFO might not be enough to cover the massive Capex, leading to negative FCF. This is perfectly fine as long as these investments eventually start generating high sales and profits in the future.

However, negative FCF is a major red flag for mature companies in slow-growing industries. If a company has been operating for decades but still spends more cash on maintaining its old factories than it generates from operations, it is a cash-destroying machine. As an investor, you want to see a clear path to positive and growing Free Cash Flow.
