What a cash flow statement is

The income statement can say a company is profitable and still be lying to you about its cash position — not through fraud, just through how accrual accounting works. A company books revenue the moment it sells something, even if the customer hasn’t paid yet. It books depreciation as a cost even though no cash actually leaves the building that day. Profit is an accounting opinion; cash is a fact.

The cash flow statement strips all of that away and answers one plain question: how much actual cash came in and went out, and where from? It splits the answer into three buckets:

  • Cash from Operations (CFO) — cash generated by the actual business: running the factory, selling snacks, collecting from distributors.
  • Cash from Investing (CFI) — cash spent on (or received from) long-term assets, mainly capex — buying or expanding the plant.
  • Cash from Financing (CFF) — cash from loans, repayments, and dividends — money moving between the company and its lenders/shareholders.

Add the three together and you get the change in the company’s cash balance for the year — which should match the difference between last year’s closing cash and this year’s, on the balance sheet. If it doesn’t, something’s wrong.

🧒 Explain it like I'm 10 (optional — skip if this is already clear)

You do ₹500 of chores for your neighbours this month (operating), but two of them still owe you ₹100 and haven’t paid yet. You also buy a new bicycle for ₹200 (investing) and your parents give you a ₹50 top-up to your piggy bank (financing). Your “profit” from chores is ₹500, but the actual cash that landed in your hand is less — because ₹100 of it is still a promise, not money. That gap between what you earned and what you actually have is exactly what a cash flow statement tracks.

Worked example: Desi Bites Foods, FY25

Desi Bites builds its cash flow statement starting from PAT and adjusting for non-cash items and working capital changes — a simplified version of the standard “indirect method”:

  ₹ Lakh
PAT 209
+ Depreciation (non-cash) 115
± Working capital changes (inventory, receivables, payables — see below)
= Cash from Operations 326
Capex (plant spend) -80
= Cash from Investing -80
Loan draw/repayment, dividend paid  
= Cash from Financing -144
Net change in cash 102
Opening cash 178
Closing cash 280

PAT for FY25 was ₹209L. Add back depreciation (a real cost, but not a cash one), adjust for the fact that inventory and receivables grew (cash tied up in stock and in what distributors owe, but haven’t paid) while payables also grew (cash the company is temporarily holding onto before paying its own suppliers) — and operating cash comes out to ₹326L, higher than PAT. From there, Desi Bites spent ₹80L expanding the plant and used ₹144L net on loan repayment and dividends, landing at a closing cash balance of ₹280L — which is exactly what shows up on the balance sheet for the same year.

Full three-year version, including how FY25’s lighter capex year freed up more cash than FY23 or FY24, is on the case study page.

Common mistakes

  • Assuming profit means cash. The single most common misread. A company can report a healthy PAT and still have weak or negative operating cash flow, if too much of that profit is sitting in unpaid customer invoices or growing inventory.
  • Ignoring negative operating cash flow as a red flag. If a profitable company’s CFO is negative, that’s worth understanding before anything else — it usually means working capital (inventory, receivables) is quietly eating cash faster than the business is generating it.
  • Not distinguishing growth capex from maintenance capex. Investing cash outflow that’s expanding capacity is a very different signal from outflow that’s just replacing worn-out equipment to stand still. The cash flow statement alone doesn’t always tell you which — that’s a judgment call, covered later in the Cash Flow Quality module.
  • Treating one year’s loan draw as “strong cash flow.” Financing inflows (new debt, new equity) aren’t the company generating cash — they’re the company borrowing or raising it. Operating cash flow is the number that reflects the business itself.

Takeaway: profit is an opinion, cash is a fact — the cash flow statement is where you check whether a company’s paper profit actually showed up as money in the bank.
