Cash Conversion (Operating Cash Flow ÷ Net Income)
How much of each dollar of reported net income actually came in as cash. It tests whether profits are real cash or only accounting entries.
How to calculate it
Cash conversion = net cash provided by operating activities ÷ net incomeHow to read it
- A ratio near or above 1 over several years means profit is being collected as cash. Capital-intensive companies with heavy depreciation often run well above 1.
- A ratio persistently well below 1 suggests profit is tied up in receivables and inventory: goods were shipped but not paid for, or produced but not sold.
- Add up several years of operating cash flow and net income and compare the totals. That is more reliable than any single year.
Common pitfalls
- Stock-based compensation is added back in operating cash flow because it is non-cash, so companies that pay heavily in stock show flattering cash conversion. Their true cost shows up as dilution instead.
- Operating cash flow can be improved temporarily by paying suppliers later, factoring receivables or using supplier finance programs. U.S. companies must disclose supplier finance programs (ASU 2022-04); check that note.
- Fast-growing companies need working capital, so one or two weak years can be normal. Persistent weakness is the warning sign.
- For banks and insurers, operating cash flow includes deposits, loans and premiums and means something very different. The ratio is meaningless when net income is negative.
Where to find it in a 10-K
Statement of cash flows: 'Net cash provided by operating activities' at the end of the operating section. The reconciliation from net income at the top of that statement shows exactly what drove the difference (receivables, inventory, payables, stock-based compensation).
U.S. vs. China reporting
The idea is the same in both markets. One difference: U.S. GAAP lets companies classify interest paid and dividends received in operating cash flow, while some Chinese and IFRS reporters place them elsewhere, so cross-border comparisons need care. U.S. filers also start the cash flow statement from net income (indirect method), which makes the drivers easy to see.
