What it means
Cash flow is usually presented in three buckets: operating, investing and financing. Operating covers the trading cycle, investing covers buying and selling long-term assets, and financing covers borrowing, repayment, share issues and dividends.
Adding the three together gives the net change in cash for the period. The split matters because the same net figure can mean very different things.
A business with $190,000 of net cash inflow generated entirely by operations is healthy; the same figure produced by selling a building while operations bleed money is not. Reading the mix is the whole skill.
Cash flow diverges from profit for three main reasons: non-cash charges such as depreciation, timing differences in receivables, payables and stock, and capital spending that never hits the profit line in full. A growing business often shows rising profit alongside falling cash, because growth consumes working capital before it returns it.
That pattern is entirely normal and still dangerous if it is unfunded. Managers use cash flow to answer practical questions about whether payroll can be met, whether the loan can be serviced and whether a new site can be funded without borrowing.
Lenders use operating cash flow to test whether interest and repayments are comfortably covered. Investors watch free cash flow, which is operating cash flow less capital spending, as the closest thing to what an owner could actually take out.
The direct method lists actual receipts and payments, while the indirect method starts with profit and adjusts for non-cash items and working capital movements. Most published statements use the indirect method, which is why the first line of a cash flow statement is usually profit rather than money.
Both routes arrive at exactly the same closing cash figure.
In practice
Real-world examples
Example 1
A recruitment agency reports a profit of $220,000 but ends the year with less cash than it started. Clients now pay in 75 days rather than 45, so receivables grew by $260,000 and swallowed the profit. The owner introduces staged invoicing and a credit control routine to pull the cycle back.
Example 2
A food manufacturer generates $1,800,000 of operating cash flow but spends $1,600,000 on a new production line. Free cash flow is therefore only $200,000, even though the trading performance was strong. The board accepts the squeeze because the line adds capacity that will lift cash generation from the following year.
Example 3
A discount retailer sells goods for cash and pays suppliers 60 days later, so opening a new store actually releases cash in the short term. Each additional store generates money before it needs to be paid for. The chain funds much of its expansion from that negative working capital cycle rather than from borrowing.
Think of it
Cash flow is like the fuel gauge in a car. Just as you need to ensure there is enough fuel to keep your car running smoothly, you need to monitor cash flow to keep your business operating efficiently.
Formula
Calculation
Net Cash Flow = Operating Cash Flow + Investing Cash Flow + Financing Cash Flow
A furniture maker reports net profit of $430,000 for the year. Adding back depreciation of $150,000 and an increase in payables of $90,000, then deducting an increase in receivables of $50,000, gives operating cash flow of $430,000 + $150,000 + $90,000 - $50,000 = $620,000.
It buys machinery for $310,000 and sells an old van for $60,000, so investing cash flow is $60,000 - $310,000 = minus $250,000. It draws a new loan of $100,000, repays $180,000 of existing loans and pays a dividend of $100,000, so financing cash flow is $100,000 - $180,000 - $100,000 = minus $180,000.
Net Cash Flow = $620,000 - $250,000 - $180,000 = $190,000.
The company opened the year with $310,000 in the bank, so it closes with $310,000 + $190,000 = $500,000. The quality of that result is good, because the cash came from trading rather than from asset sales or new borrowing.Case study
Seen in the real world
Tallow Bay Brewing is a fictional craft brewery used here purely as an illustrative example. In its fourth year it reported a profit of $310,000, its best result yet, and the founders were surprised to find the bank balance almost unchanged.
The cash flow statement explained it. Profit of $310,000 plus depreciation of $120,000 came to $430,000, but receivables rose by $180,000 as the brewery took on supermarket customers with long payment terms, stock rose by $205,000 as it built up cans and kegs for summer, and payables rose by only $50,000. Operating cash flow was therefore $310,000 + $120,000 - $180,000 - $205,000 + $50,000 = $95,000.
In this illustrative story Tallow Bay renegotiated supermarket terms from 60 days to 35, released about $140,000 of trapped cash, and lifted operating cash flow to roughly $95,000 + $140,000 = $235,000 the following year on similar profit. Nothing about the beer changed; only the timing of the money did.
Watch out
Common mistakes
- Treating profit and cash flow as the same number, then wondering why the bank balance disagrees with the accounts.
- Celebrating a positive net cash figure without checking whether it came from trading, an asset sale or new debt.
- Ignoring that fast growth consumes cash, so a rising order book can be the thing that breaks the business.
Questions
People also ask
What is free cash flow?
It is operating cash flow less the capital spending needed to keep the business running, and it approximates what is genuinely available to lenders and owners.
Why does depreciation get added back?
Because it is an accounting charge that spreads the cost of an asset over its life, and no money leaves the bank in the year the charge is recorded.
Can a profitable company run out of cash?
Yes, and it is common, because profit can be earned long before customers pay while wages, rent and suppliers still have to be settled on time.
