Cash Flow Statement Methods: Inventory Adjustments
Compare direct and indirect operating cash flows, calculate inventory working-capital adjustments, and derive cash paid to suppliers step by step.
Quick answer
Under the indirect method, an inventory increase is ordinarily subtracted from net income and a decrease in inventory is ordinarily added. Under the direct method, inventory changes help convert cost of goods sold into purchases before accounts payable converts purchases into cash paid to suppliers.
Quick answer: inventory is an operating working-capital adjustment
The sign is not a slogan detached from the facts. Trace the inventory and payable roll-forwards, then isolate noncash acquisitions, write-downs, business-combination balances, foreign exchange, or other items stated in the problem.
Worked example: derive cash paid to suppliers
- 1Assume cost of goods sold is $420,000, inventory rises from $120,000 to $150,000, and accounts payable falls from $70,000 to $60,000. Ignore other reconciling items for this focused example.
- 2Purchases equal $420,000 plus the $30,000 inventory increase, or $450,000. Because accounts payable decreased by $10,000, the company paid $10,000 more cash than current purchases. Cash paid to suppliers is therefore $460,000.
- 3Under the indirect method, subtract both the $30,000 inventory increase and the $10,000 payable decrease from net income. After the example, try free FAR practice and explain each sign in words.
| Step | Calculation | Amount |
|---|---|---|
| Cost of goods sold | Given | $420,000 |
| Add inventory increase | $150,000 ending - $120,000 beginning | $30,000 |
| Inventory purchases | $420,000 + $30,000 | $450,000 |
| Add accounts-payable decrease | $70,000 beginning - $60,000 ending | $10,000 |
| Cash paid to suppliers | $450,000 + $10,000 | $460,000 |
| Working-capital change | Indirect adjustment | Cash interpretation |
|---|---|---|
| Inventory increases $30,000 | Subtract $30,000 | Purchases exceeded inventory expense |
| Accounts payable decreases $10,000 | Subtract $10,000 | Cash payments exceeded purchases recognized through payable |
| Combined effect in this example | Subtract $40,000 | Working capital used operating cash |

The inventory bridge is beginning inventory plus purchases minus cost of goods sold equals ending inventory in the simple fact pattern. Rearranging gives purchases equal cost of goods sold plus ending inventory minus beginning inventory.
The payable bridge is beginning accounts payable plus credit purchases minus cash paid equals ending accounts payable. Rearranging gives cash paid equal purchases plus beginning payable minus ending payable.
Inventory valuation methods belong to LIFO versus FIFO. Physical-count corrections belong to inventory adjustment journal entries. This route owns the cash-flow conversion, not valuation or shrinkage measurement.
- 1Start with COGSUse cost of goods sold as the accrual-basis inventory expense in the basic conversion.
- 2Convert expense to purchasesAdd an inventory increase or subtract an inventory decrease, subject to other stated inventory items.
- 3Convert purchases to cashAdd a payable decrease or subtract a payable increase.
- 4Check extra factsAddress noncash acquisitions, foreign exchange, business combinations, and classification facts separately.
Compare the operating sections without changing the total
| Question | Direct method | Indirect method |
|---|---|---|
| Starting point | Gross classes of operating receipts and payments | Net income |
| Inventory appears as | Part of deriving cash paid to suppliers | Working-capital adjustment |
| Operating cash flow total | Same total when both are prepared correctly | Same total when both are prepared correctly |
| Investing and financing sections | Unaffected by operating presentation choice | Unaffected by operating presentation choice |
Apply a statement-wide cash-flow checklist
Classify each cash and noncash event first. Then prepare operating cash flows using the required method, reconcile inventory and payables independently, and disclose significant noncash investing and financing activity as the question requires.
For indirect questions, start at the specified income measure and separate noncash expenses, gains or losses, and operating working-capital changes. For direct questions, derive each gross receipt or payment from its related income-statement and balance-sheet accounts.
Use the FAR section hub for broader statement scope, the 2026 CPA Exam Blueprints for current scope, and trial balance for pre-statement adjustments. Check that ending cash agrees with the comparative balance sheet after all three cash-flow categories are complete.
Frequently asked questions
How does an increase in inventory affect cash flow under the indirect method?
An increase in inventory is ordinarily subtracted in the operating section under the indirect method because cash was used to acquire more inventory than the amount reflected through cost of goods sold, subject to the complete facts and other adjustments.
How do you calculate cash paid to suppliers?
In a basic fact pattern, first derive purchases as cost of goods sold plus an increase in inventory, or minus a decrease. Then adjust purchases for accounts payable: add a decrease in payable or subtract an increase.
Do direct and indirect methods change investing and financing cash flows?
No. The method choice changes how operating cash flows are presented. Investing and financing classifications do not change merely because the operating section uses direct or indirect presentation.
