Cash Flow From Operations: The Indirect Method

Introduction

The indirect method begins with a number that is not cash. Operating cash flow on almost every US cash flow statement starts from net income, a figure built on accruals, estimates and allocations, and then reverses each item that made profit differ from cash. Costco's fiscal 2025 statement is a typical example: $8.1 billion of net income at the top, then a series of adjustments, and $13.3 billion of cash from operations at the bottom.

The method looks roundabout, since a company could simply list the cash it received and paid. Its value lies in the bridge itself. Each adjustment explains a specific reason why earnings and cash diverged in the period: non-cash expenses, gains whose cash belongs elsewhere, and money tied up in or released from working capital. For a banker, reading that bridge is the fastest way to judge whether reported earnings are turning into cash, and the logic behind it is the basis of most accounting interview questions about the cash flow statement. How the operating section fits alongside investing and financing is shown in how the cash flow statement works.

Accounting Standards Codification (ASC) 230, the cash flow topic of US generally accepted accounting principles (GAAP), allows companies to present operating cash flow either by the direct method, as a list of receipts and payments, or by the indirect method, as a reconciliation from net income. Deloitte's roadmap on the form and content of the statement of cash flows summarizes what the reconciliation must do: remove items that did not affect operating cash, such as depreciation and amortization; remove gains and losses whose cash effects belong to investing or financing, such as gains on selling equipment or on retiring debt; and show changes in receivables, inventory and payables related to operations, at a minimum. A company that uses the direct method must still provide the reconciliation, which is one reason almost every company uses the indirect method.

Indirect method

A way of presenting cash flow from operating activities that starts with net income and adjusts it for non-cash items, for gains and losses whose cash effects belong in investing or financing activities, and for changes in operating working capital, arriving at the cash generated by operations.

In compact form:

Each term reverses a different kind of accrual, the timing differences described in accrual vs cash accounting. Non-cash charges reduced net income without using cash. Non-cash gains increased net income without bringing cash into operations. And the change in working capital captures the timing gap between revenue and expenses recorded and cash actually received and paid.

The first and usually largest adjustments add back expenses that reduced net income but did not require a cash payment in the period:

The reason each one is added back is the same: it is a cost on the income statement whose cash, if any, appears somewhere else or at another time.

Accrued charges deserve a separate thought. A restructuring charge for severance, or a provision for a lawsuit, reduces net income when it is recorded but may be paid months later. In the year of the charge, the expense is effectively added back through the increase in accrued liabilities; in the year of payment, the decrease in those liabilities reduces operating cash flow with no corresponding expense. A company that removes restructuring charges from its adjusted earnings therefore still pays for them in operating cash flow later, which is one reason cash flow often looks weaker than adjusted earnings after a reorganization. The detail behind each item, and the traps in each, are covered in non-cash items on the cash flow statement.

Stock-Based Compensation: The Most Debated Add-Back

Stock-based compensation is added back for the same mechanical reason as depreciation, but it is economically different. Employees were paid; they were simply paid in shares rather than cash, and existing shareholders bear the cost through dilution or through the buybacks a company makes to offset it. At large technology companies the add-back is substantial: Microsoft's fiscal 2025 Form 10-K shows about $12.0 billion of stock-based compensation added back. Operating cash flow and free cash flow that include the add-back therefore overstate the cash a business would generate if it paid its people entirely in cash. Many analysts subtract it again when comparing companies, or count the cash spent on buybacks to neutralize dilution as a cost of the business. The expense itself is explained in stock-based compensation accounting.

Some items in net income relate to cash flows reported in other sections. Leaving them in operating cash flow would count their cash twice or in the wrong place. The reconciliation therefore removes:

Equity Method Income and Dividends Received

Equity method investments show the logic of this step clearly. Suppose a company owns 30% of an affiliate that earns $100 million and pays out $40 million in dividends. The company records $30 million of equity method income in net income, but receives only $12 million in cash. The reconciliation therefore subtracts the $30 million of non-cash income and adds back the $12 million of dividends, often netted as a single $18 million deduction labeled undistributed earnings of affiliates. If cumulative dividends ever exceeded the company's cumulative share of the affiliate's earnings, the excess would generally be treated as a return of the investment and shown in investing activities.

Losses work in the opposite direction: a loss on sale is added back, because it reduced net income while the sale proceeds appear in investing. The rule is simple once the principle is clear: net income should be stripped of anything whose cash belongs to investing or financing, so that the operating section contains only operating cash.

The last group of adjustments captures timing. When revenue is recorded before cash is collected, receivables rise and operating cash flow is lower than net income; when suppliers are paid later than costs are recorded, payables rise and operating cash flow is higher. The sign logic follows from the balance sheet: an increase in an operating asset uses cash and is subtracted, and an increase in an operating liability provides cash and is added. Decreases work the other way. The full set of rules, with worked examples for each balance, is in working capital on the cash flow statement.

The same logic covers the less obvious balances. An increase in income taxes payable means tax expense was recorded but not yet paid, so it adds to cash; a rise in prepaid expenses means cash left before the cost was expensed, so it subtracts. Many companies group these smaller items into a single line for other operating assets and liabilities, which can hide meaningful movements in customer deposits, accrued bonuses or tax balances. When that catch-all line is large relative to operating cash flow, the notes or management's discussion usually explain what drove it, and it is worth finding out before relying on the total.

Why the Cash Flow Changes Do Not Match the Balance Sheet

A common surprise is that the working capital changes on the cash flow statement rarely equal the differences between the two balance sheets. The reason is that some balance sheet changes involve no operating cash. When a company buys another business, the target's receivables, inventory and payables arrive on the balance sheet as part of the acquisition, paid for through the single acquisition outflow in investing activities; counting them again as working capital changes would double count the cash. Currency translation moves the dollar value of foreign subsidiaries' balances without any cash flow, and divestitures remove balances in the same way. The cash flow statement reports only the operating changes, which is why a banker reconciling the two statements should expect gaps in a year with acquisitions or large currency moves, and should use the cash flow statement figures, not balance sheet differences, when measuring working capital investment.

Putting the Three Steps Together

Consider a distribution company with $120 million of net income. Its income statement includes $40 million of depreciation, $10 million of stock-based compensation, $6 million of deferred tax expense and a $5 million gain on selling a warehouse. During the year its receivables rose by $30 million, inventory by $20 million, payables by $15 million and accrued liabilities by $4 million, while deferred revenue fell by $2 million:

Operating cash flow of $138 million exceeds net income by $18 million: net non-cash adjustments added $51 million, but working capital growth tied up $33 million, mostly in receivables and inventory. For a growing distributor, that pattern is normal; the question is whether working capital is growing in line with sales or faster.

Costco's fiscal 2025 annual report shows a real reconciliation, and a business model whose working capital usually helps rather than hurts cash flow:

Two features stand out. Operating cash flow is about 1.6 times net income in fiscal 2025, a high conversion driven by non-cash charges and favorable working capital. And the working capital lines show how Costco's model works: in fiscal 2024, inventory grew by $2.1 billion, but payables grew by $1.9 billion, so suppliers financed almost all of the inventory build. In fiscal 2025 inventory fell slightly and payables still rose, releasing cash. Membership fees paid in advance, included in other operating liabilities, add a further source of cash as membership grows.

What the Bridge Says About Costco's Model

The membership model shows up directly in the balance sheet behind the reconciliation. Deferred membership fees, cash collected from members for the year ahead and recognized as revenue over the membership period, rose from $2.5 billion to $2.9 billion during fiscal 2025, so growth in membership adds cash before it adds revenue. Combined with payables that fund inventory, that structure means Costco's operating cash flow tends to rise faster than its earnings as the business grows, the opposite of a manufacturer selling on credit.

Cash conversion

The proportion of a company's earnings that turns into operating cash flow, usually measured as operating cash flow divided by net income or by earnings before interest, taxes, depreciation and amortization (EBITDA), or as free cash flow divided by net income. Persistently low cash conversion can signal working capital problems or aggressive accounting.

Conversion ratios are only comparable within an industry. A retailer collecting from shoppers at the till and paying suppliers on credit can convert well above 100% of net income, as Costco does; a manufacturer extending 60-day terms to customers and holding months of inventory may convert well below it in a growth year, without anything being wrong. The useful comparison is with peers and with the company's own history.

The indirect method is mechanical, but a few mistakes recur, in models and in interviews alike. The most common is getting the working capital signs backwards, treating an increase in receivables as a source of cash. Another is adding back a non-cash charge that was never deducted from net income, such as capitalized costs, or adding back a charge twice when it appears both in a separate line and within another adjustment. A third is leaving a gain on sale in operating cash flow while also counting the full proceeds in investing. A fourth is forgetting that under US GAAP interest paid is already inside operating cash flow, because it was deducted in net income: subtracting it again double counts it, and building unlevered free cash flow from operating cash flow requires adding it back after tax.

Beyond the mechanics, bankers read the reconciliation for signals about earnings quality. Operating cash flow persistently below net income, with receivables or inventory growing faster than sales, can indicate aggressive revenue recognition or slowing collections, patterns discussed in accounting red flags. Large and growing stock-based compensation add-backs inflate operating cash flow relative to the economic cost of paying employees, which is why many analysts deduct stock compensation when they compare free cash flow across companies. And rising deferred tax add-backs mean cash taxes are running below the tax expense reported in earnings, which may or may not continue.

The Bridge in Models and Interviews

Financial models build projected operating cash flow the same way the indirect method presents it: projected net income, plus projected depreciation, amortization and stock compensation, less the projected increase in working capital driven by days assumptions. Getting the three-step logic right is what makes a projected balance sheet balance, a modeling point covered in the Valuation guide's article on the three-statement model. The same logic underpins one of the most frequent interview questions, asking a candidate to explain how net income becomes operating cash flow, which is approached as a spoken answer in walking through the three statements.

The indirect method's bridge is ultimately a list of reasons. Each line answers why this period's cash differed from this period's profit, and a banker who can read those reasons can tell whether a company's earnings are backed by cash, financed by its suppliers, or temporarily flattered by a working capital release. Those reasons, read over several years and against peers, are what turn a reconciliation into analysis.
