Free cash flow: what the business actually keeps.
Profit is what accountants record. FCF is what the business can spend.
The profit Ravi earned — and couldn't take home
Ravi's kirana store had a record year. The accountant printed the profit statement — numbers that made him smile. Then his wife asked a simple question: where is the money? The bank account looked thinner than expected. The profits were real. The cash, somehow, was not.
Profit is what accountants record. It follows strict rules — when to recognise revenue, how to treat depreciation, when to expense an item and when to capitalise it. A company can show growing profit quarter after quarter while its bank account stays flat or shrinks. Cash flow ignores those accounting conventions. It counts only what physically arrived — cash in and cash out, nothing more and nothing less.
Free cash flow has a simple formula: Operating Cash Flow minus Capital Expenditure. Operating cash flow is the cash the business generates from its core activity — selling goods, providing services, collecting payments from customers. Capital expenditure is what it spends to maintain existing equipment, upgrade infrastructure, or build entirely new capacity for the future.
Asset-light businesses convert most of their profit into FCF. A software company writes code. It needs laptops and office space, not blast furnaces or transmission towers. For every ₹100 of profit it reports, most arrives as real, spendable cash. A steel plant also earns ₹100 but must reinvest a large portion back into maintenance just to stay in operation. Without that reinvestment, the plant degrades and the business eventually stops. That constant reinvestment is not profit — it is the ongoing cost of staying alive.
FCF is the money a company can actually deploy. Dividends come from FCF. Share buybacks come from FCF. Debt repayment comes from FCF. Acquisitions come from FCF. Profit is a score on paper. FCF is the prize money sitting in the bank.
What Ravi can actually put in his locker
Ramesh runs a kirana store. He earns ₹5 lakh profit this year. He also buys a new refrigerator for ₹2 lakh to stock cold drinks — a necessary upgrade, not a luxury. That money is gone from the business. Ramesh cannot put the full ₹5 lakh in his home locker and call it free. Only ₹3 lakh is truly his to use — for savings, family needs, or investment elsewhere. Free cash flow is exactly what lands in the locker: profit after paying for what the business needs to keep running.
Why this matters
When you read a company's annual report, go to the Statement of Cash Flows. Every listed company in India must publish one — it is a legal requirement under Ind AS 7. Find operating cash flow. Subtract capital expenditure. That is the FCF. Divide it by the company's market cap to get the FCF yield. If the FCF yield exceeds what your FD currently offers, the business generates more cash per rupee invested than a completely risk-free deposit. That is not an automatic signal to act. There are quality differences, growth assumptions, and risks to weigh. But it is where honest valuation begins — in cash, not in accounting profit.
Move the slider. Watch profit shrink to real cash.
Try the widget below. Adjust how much of the operating cash flow goes back into capex and watch ₹100 of OCF shrink, in real time, into what the business actually keeps. The gap between reported profit and free cash is not failure — it is the price a business pays for staying in business.
How much of operating cash does the business actually keep?
Out of ₹1,000 of operating cash, 30 goes back into maintaining and growing the business. That leaves ₹700 — the free cash flow, or 70 of OCF. This is what funds dividends, buybacks, and debt repayment. Profit is what the accountant records; FCF is what the business can actually spend. Asset-light businesses like IT and FMCG keep 70–90%; steel and telecom firms often keep less than 20%.
Check the cash. Not just the profit.
Where people go wrong
- Trusting net profit without checking the cash flowA company can book revenue the moment goods are delivered, even if the customer pays 90 days later. Profit can look healthy and growing while the actual bank balance shrinks. The Statement of Cash Flows shows what physically arrived.
- Calling a company cash-rich when FCF is negativeProfit sitting in receivables or inventory is not spendable — it is a claim on future cash. If FCF is consistently negative, the business is consuming more cash than it generates. The balance sheet profit headline can mislead you entirely.
- Penalising growth companies for years of negative FCFReliance Jio's FCF was deeply negative while it built India's 4G network. Those were years of deliberate investment, not distress. Always separate growth capex from maintenance capex — one builds future earnings, the other just keeps the lights on.
- Comparing FCF yields across different sectors directlyA steel plant needs heavy ongoing capex just to stay operational. An IT firm barely spends on equipment. The same FCF yield number tells very different stories in very different industries.
FCF = Operating Cash Flow minus Capex — the cash a business actually keeps after staying operational.
Asset-light companies convert most profit to FCF; capital-heavy ones often cannot, and that is normal.
FCF yield compared to your FD rate is the first honest test of whether a stock earns its keep.
Profit headlines appear on the first page of every financial summary; the Statement of Cash Flows is buried deep in the annual report, full of arithmetic that most investors skip. The business speaks in cash — but most investors only listen to accountants.
