A company reports Rs 80 crore of profit after tax. The board celebrates the performance. The investor presentation highlights the earnings.
But the bank account shows Rs 35 crore of operating cash flow. The Rs 45 crore gap between reported profit and actual cash generated is the cash conversion question: can the company’s accounting profit actually become cash?
The gap is not necessarily a problem. Working-capital consumption during growth, non-cash charges (depreciation, amortisation), timing differences between accrual recognition and cash receipt, all can create legitimate divergence between profit and cash flow. The question is whether the divergence is temporary (the cash will arrive in future periods) or structural (the profit is recognised in the P&L but will never fully convert to cash).
The Conversion Chain
Reported PAT → add back non-cash charges → operating cash flow before working capital → adjust for working-capital changes → operating cash flow → deduct maintenance capex → deduct tax actually paid → free cash flow
At each step, value can leak:
Non-cash revenue. Revenue recognised through accruals where the cash collection is uncertain: revenue from customers with deteriorating credit quality, revenue recognised under percentage-of-completion where the project outcome is uncertain, revenue from long-term contracts where variable consideration has been estimated optimistically.
Working-capital consumption. Receivable days expanding. Inventory building. Payable days shortening. Each movement consumes cash that the P&L does not reflect. A company can report Rs 80 crore of profit and consume Rs 30 crore of cash in working capital, leaving only Rs 50 crore of operating cash flow.
Maintenance capex disguised as growth capex. A company that classifies the replacement of a worn-out production line as “growth capex” rather than “maintenance capex” understates its maintenance burden. Free cash flow after maintenance capex is the economic cash generation. Free cash flow after total capex includes the effect of discretionary growth investment.
Tax timing. Tax expense in the P&L (based on accounting profit and deferred tax calculations) frequently differs from tax actually paid. The cash tax payment is the economically relevant figure.
The Quality Metrics
Cash conversion ratio (CCR) = Operating cash flow / EBITDA. A CCR consistently above 80% indicates strong cash conversion. A CCR consistently below 60% indicates structural cash-conversion weakness.
Free cash flow yield = Free cash flow / enterprise value. This measures the actual cash return the business generates on its total capitalisation. A company trading at 15x EBITDA but generating a 3% free cash flow yield has a valuation that the cash economics may not support.
Cash earnings ratio = Operating cash flow / reported net profit. A ratio consistently above 0.8 indicates that reported profit is converting to cash. A ratio consistently below 0.5 indicates that more than half of reported profit is not being collected as cash within the reporting period.
The Forensic Application
In Northrop Management Private Limited’s forensic and due diligence practice, the Cash Conversion Test is applied to every earnings quality assessment.
The methodology: calculate the cash conversion ratio, the free cash flow yield and the cash earnings ratio for each of the last five years. Plot the trend. If conversion is deteriorating (the ratios are declining), investigate the cause: working-capital expansion, ageing receivables, inventory build, capex misclassification or revenue recognised ahead of collection.
The investigation follows the forensic chain: identify the divergence between profit and cash, trace it to the specific balance sheet line items causing the leak, verify the documentation supporting those items and assess whether the economic substance matches the accounting treatment.
Ashish Chaudhary, frames the diagnostic directly: “Cash is where accounting claims meet economic reality. A company whose profit consistently converts to cash at 90% or above has earnings that are real. A company whose profit converts at 50% has earnings that are partly real and partly accounting. The Cash Conversion Test tells the board which portion is which.”
Questions for the Boardroom
- What is our cash conversion ratio (operating cash flow / EBITDA) for each of the last five years, and is the trend improving or deteriorating?
- What is the largest single source of divergence between reported profit and operating cash flow?
- If we separated maintenance capex from growth capex, what would our free cash flow after maintenance be?
- How does our cash tax payment compare to our reported tax expense, and what drives the difference?
- If an investor evaluated us on free cash flow yield rather than EBITDA multiple, would the conclusion about our valuation change?
Closing Implication
Profit is an opinion. Cash is a fact. A company that reports Rs 80 crore of profit and generates Rs 80 crore of operating cash flow has demonstrated that its accounting and its economics tell the same story. A company that reports Rs 80 crore of profit and generates Rs 35 crore of cash flow has a Rs 45 crore question that only the balance sheet and the cash flow statement can answer.
The Cash Conversion Test does not assume the profit is wrong. It tests whether the profit is real, meaning backed by cash that the company can reinvest, distribute, use to service debt or hold as liquidity. Profit that does not convert to cash is not worthless. But it is worth less than profit that does.
