Free cash flow, simply explained

In short

Free cash flow is the money a company has left after paying all running costs and investing in its business. It is harder to dress up than profit. It is what a company uses to pay dividends, buy back its own shares or pay down debt.

What is really left over

Picture a baker. At the end of the year he has sold bread and paid for flour, electricity and wages. What is left, the accountants call profit. But this year the baker also had to buy a new oven. That money is gone, even though the oven shows up in the profit figures only bit by bit over many years.

Free cash flow therefore asks a practical question: how much more money is actually in the account at the end of the year – after everything that keeps the business running? That is exactly the money a company can pass on to its owners.

The formula

Free cash flow=Operating cash flow−Capital expenditure
Operating cash flow
money the ongoing business brings in during the year
Capital expenditure
spending on machines, buildings, software and the like

Both figures are in the cash flow statement, a mandatory part of every annual report. Operating cash flow is usually called "cash from operating activities", capital expenditure "purchases of property and equipment" or similar.

The worked example

In the article on fair value, the made-up Example Inc. had a free cash flow of €10 per share. This is how it could arise from profit:

Example Inc. · from profit to free cash flowper share
ItemAmount
Profit€11.00
+ Depreciation€4.00
− more money tied up in inventory and unpaid invoices€1.00
= Operating cash flow€14.00
− Capital expenditure€4.00
= Free cash flow€10.00
Made-up company.

How to read the table: depreciation is a cost that lowers profit, but no money left the company for it this year – the oven was paid for earlier. That is why it is added back. On the other hand, more money got tied up in inventory and in invoices customers have not paid yet. That is missing from the account and is subtracted. The result is €10 – a little less than profit.

Why profit and cash flow drift apart

Profit follows accounting rules, cash flow follows the money. Both are useful, but they can be far apart:

A growing company often invests much more than it depreciates. Its free cash flow is then below profit, even though it is healthy. A company that hardly invests any more, on the other hand, shows free cash flow above profit – that looks good, but may mean it is living off its substance.

It is a warning sign when profit rises for many years but free cash flow does not keep up. Then the profit is apparently not arriving in the account as money.

Free cash flow per share and yield

Divide free cash flow by the number of shares and you get free cash flow per share. Divide that by the share price and you get the free cash flow yield. If a share of Example Inc. costs €200, that is €10 ÷ €200 = 5%. It tells you how much money the company earns relative to what you pay for it – similar to the P/E ratio, but based on cash instead of profit.

Three common mistakes

1
Looking at one year onlyFree cash flow swings a lot, for example when a company builds a new factory in one year. Always look at several years. Only the trend shows what a company has left over in the long run.
2
Overlooking stock-based payMany companies pay employees partly in shares. No money leaves operating cash flow for this, so it looks higher. Shareholders still bear the cost, because new shares dilute their stake.
3
Celebrating cut investmentCutting capital expenditure lifts free cash flow immediately – at the expense of the future. A sudden jump is therefore worth a look at whether the company is simply investing less in itself.

Frequently asked questions

Is negative free cash flow bad?

Not necessarily. Young or fast-growing companies often invest more than they take in. What matters is whether the investments bring in money later and whether the company can finance the time until then.

How is it different from EBITDA?

EBITDA is earnings before interest, taxes, depreciation and amortization. It leaves out investment, taxes and interest entirely. Free cash flow subtracts all of that and is therefore closer to the money that is really left over. What EBITDA is still useful for is shown in the article EV/EBITDA.

Where do I find free cash flow?

Many companies state it in their annual report. If not, you calculate it yourself from the cash flow statement: operating cash flow minus capital expenditure. Note that different sources define it slightly differently.

Why does a DCF use free cash flow and not profit?

Because in the end a company can only give its owners money it actually has. A DCF estimates exactly that money for the future and discounts it back to today.
