Ask which number answers your question
An income statement measures a period’s reported earnings under its accounting policies. Operating cash flow concerns cash generated or used by operating activities. The SEC’s financial-statements guide explains that the cash-flow statement reconciles noncash items and operating-balance changes. Neither measure is simply a synonym for the ending bank balance.
For an educational comparison, use the same reporting period, entity scope and units for both. A quarterly income figure and a year-to-date cash-flow figure will not form a valid bridge merely because they appear in the same filing. Read the headings and notes before doing arithmetic.
Build an original profit-to-cash bridge
Stipulate an invented company with $200 revenue and $170 expenses, including $10 depreciation. Assume no tax, interest or other income-statement items. Net profit is therefore $30. Over the same period, receivables rise by $40, inventory rises by $15 and operating payables rise by $5. Assume no other operating adjustments.
Start with $30 profit, add back the $10 noncash depreciation, subtract the $40 receivable increase and $15 inventory increase, then add the $5 payable increase. Operating cash flow is $30 + $10 − $40 − $15 + $5 = −$10. The company has a profit in the stipulated accounts while using operating cash.
Cross-check with cash receipts and payments
Under these same simplified assumptions, $200 revenue less the $40 receivable increase gives $160 cash collected. Cash operating payments are $170 expenses less $10 depreciation, plus $15 additional inventory, less the $5 increase in payables: $170. Receipts of $160 minus payments of $170 reproduce the −$10 operating cash flow.
This direct cross-check is an internal consistency exercise. It does not establish that a real company recognized revenue properly, will collect its receivables or has sufficient funding. The invented balance changes were selected to explain the bridge, not to represent a benchmark for a healthy business.
Keep capital spending and financing separate
Add an invented $20 equipment purchase and $50 new borrowing, with no other cash movements. The equipment cash outflow belongs in the stipulated investing column; the loan inflow belongs in financing. Total cash changes by −$10 − $20 + $50 = +$20. A rising cash balance would therefore coexist with negative operating cash flow in this example.
Investigate the reason for a real divergence rather than declaring one measure superior. Growing sales may require more inventory and customer credit; other cases may involve collection problems or delayed supplier payments. Repeat the reconciliation over comparable periods and examine disclosures. The bridge identifies questions; it does not answer them automatically.

All figures and accounting simplifications are hypothetical. Arithmetic and the SEC educational source were checked on 26 October 2026. The worksheet is not an audit, a complete accounting policy or a credit or investment recommendation. Classification and recognition details must be checked in the relevant entity’s actual statements and applicable accounting framework.
