Free Cash Flow vs Net Profit: Which One Tells You More About a Business?

Table of Contents

A company can report a record profit and still be running short of money, which sounds like an accounting riddle until you look at how the two numbers are worked out. Net profit follows accounting rules that record a sale when it’s made, even if the customer hasn’t paid yet. Free cash flow only counts money once it comes in or goes out. Comparing free cash flow vs net profit side by side shows if a business is turning its earnings into cash it can use, and when the two drift apart, it’s usually the cash figure that’s closer to the truth.

Quick answer: Net profit is what a company earns under accounting rules after all costs, while free cash flow is the cash left over after running the business and paying for equipment and other investment. Free cash flow usually tells you more about financial health, because it shows the money available for dividends, buybacks and paying down debt.

How Free Cash Flow Is Worked Out

Free cash flow starts with the cash a business makes from its day-to-day operations and takes away what it spends on long-term assets like factories, machinery, software and vehicles.

Free cash flow = cash from operations − capital expenditure

Cash from operations is net profit adjusted for anything that didn’t involve real money changing hands that year, and for changes in working capital. Those two adjustments are where most of the gap between profit and cash comes from.


Why Profit Can Look Healthy While Cash Is Weak

Capital Expenditure

When a company spends $500 million on a new factory, the income statement spreads that cost over the factory’s life through depreciation, perhaps $25 million a year for 20 years. The cash leaves the bank in the year it’s spent. A business in the middle of a big building program can report steady profit while its free cash flow drops sharply or turns negative.

TSMC shows the scale this can reach, with a 2026 capital budget of $60 billion to $64 billion, and our article on AI chip stocks looks at what that spending means for investors.

Working Capital

Working capital is the money tied up in running the business day to day.

  • Receivables: if customers are given longer to pay, sales and profit rise while the cash hasn’t arrived yet
  • Inventory: stock sitting in a warehouse has been paid for but hasn’t been sold
  • Payables: paying suppliers faster uses up cash without changing profit

A company growing quickly often needs more inventory and has more unpaid invoices, which is why fast growth can drain cash even when the business is profitable.

Non-Cash Items

Some costs and gains appear in profit without any cash moving. Share-based pay is one example. It’s recorded as a cost, though no cash is paid out, and it dilutes existing shareholders over time. A one-off gain from revaluing an asset can lift profit in the same way without adding a dollar to the bank.


A Simple Example

Here’s a made-up company that looks great on profit and much less great on cash.

Amount 
Net profit$100 million
Add back depreciation+$40 million
Customers paying more slowly−$60 million
Extra inventory−$30 million
Cash from operations$50 million
Capital expenditure−$90 million
Free cash flow−$40 million

The company reported $100 million of profit and still had to find $40 million from savings or borrowing to keep going. If it pays a dividend on top, that money has to come from somewhere too.


When Net Profit Is the More Useful Number

Free cash flow isn’t perfect. It can swing sharply from one year to the next, especially for companies that invest in big projects every few years. Net profit smooths out those lumps and gives a clearer view of underlying profitability over a single year.

The most useful approach is to look at both over several years. A business whose free cash flow broadly tracks its net profit over time is usually turning earnings into real money. One where cash keeps falling short of profit year after year deserves a much closer look, and it’s one of the checks in our guide to spotting value traps.


What to Check in a Company’s Accounts

  • Cash conversion: free cash flow divided by net profit, where a figure close to 100% over several years is a good sign
  • Receivables growth: unpaid invoices growing faster than sales can mean customers are taking longer to pay
  • Capex trend: rising spending can mean expansion, or it can mean the business needs constant reinvestment to stand still
  • Dividend cover: a dividend larger than free cash flow is being funded from somewhere else

Free cash flow also feeds into valuation measures like price-to-free-cash-flow and free-cash-flow yield, both covered in our guide to judging if a company is cheap. The same numbers sit at the center of any good read of quarterly results, which our guide to reading an earnings report walks through.


Frequently Asked Questions

What is the difference between free cash flow and net profit?

Net profit is a company’s earnings after all costs, interest and tax, calculated under accounting rules. Free cash flow is the cash left after running the business and paying for long-term investment. Profit records sales when they’re made and spreads equipment costs over years, while free cash flow counts money only when it moves.

Can a company be profitable but have negative free cash flow?

Yes. A company can report a profit while its free cash flow is negative if it’s spending heavily on new equipment, building up inventory or waiting for customers to pay. This is common in fast-growing businesses. It becomes a concern when it lasts for years and the gap is covered by borrowing.

Is free cash flow more important than profit?

Free cash flow is often more revealing than profit because it’s harder to adjust with accounting choices and shows the money a company has available to pay dividends, buy back shares or reduce debt. Profit is still useful for judging underlying profitability, so most investors look at both over several years.

How do you calculate free cash flow?

Free cash flow is calculated by taking cash from operating activities and subtracting capital expenditure. Both figures appear on a company’s cash flow statement. For example, a company with $500 million of operating cash flow and $200 million of capital spending has free cash flow of $300 million for the year.
