Understanding Operating Cash Flow
Operating cash flow is the amount of cash generated by a company in producing and selling its products or services. Let me tell you, Amazon.com Inc. (AMZN) reported a staggering $115.9 billion in operating cash flow (OCF) in 2024, more than a third more than the year before. That's enough to buy every person in the state of California two new iPhone 16 Pros—with billions left over.
While OCF is a financial metric that's less glamorous than profit margins, it's arguably more important. I'll take you through the details below.
Key Takeaways on OCF
Operating cash flow (OCF) is the first section of a cash flow statement, showing cash from operating activities. You calculate OCF using an indirect or direct method. The indirect method starts with net income, which you then adjust for non-cash items. The direct method tracks actual cash transactions. A positive OCF indicates that a company can fund its operations from its core business activities without relying on external financing or investment capital.
What Is Operating Cash Flow (OCF)?
OCF measures the amount of cash generated by a company's core business operations over a specific period. It's the cash inflows and outflows directly related to producing and selling the company's products or services. OCF specifically excludes cash flows from investing activities (like purchasing equipment) and financing activities (such as issuing stock or paying dividends).
Specifically, you can formulate OCF as follows: OCF = Net Income + Non-Cash Expenses - Increase in Working Capital. OCF provides a clear picture of how much cash a business generates from its day-to-day operations before considering any external funding sources or capital expenditures.
This makes OCF crucial when assessing a company's operational efficiency and whether it's sustainable financially. By focusing solely on core business operations, OCF helps you determine whether a company can support itself through its primary business model. Companies report OCF as part of their cash flow statement, which breaks down all cash movements into three categories: operating activities, investing activities, and financing activities.
Importance of Operating Cash Flow
OCF is a key indicator of the financial health of a company. It provides a clear picture of a company's ability to generate cash from its core business activities. Consider two lemonade stands: Stand A has high sales but mostly on credit, leading to low immediate cash, while Stand B has moderate sales mostly in cash, resulting in high OCF. Stand B shows better financial health and operational efficiency because it converts sales to cash quickly.
OCF serves as a key sign of a company's short-term liquidity to pay bills. A strong OCF signals to investors that a company can fund its operations, invest in growth, and potentially provide returns to shareholders. Companies with positive OCF are better positioned to service their debts, enhancing creditworthiness and reducing financial risk. OCF reflects a company's ability to weather economic fluctuations without external support. Additionally, the IRS considers business expenses that contribute to OCF as potentially tax-deductible.
Remember, the operating cash flow ratio represents a company's ability to pay its debts with its existing cash flows. You determine it by dividing operating cash flow by current liabilities. A ratio greater than 1.0 indicates that a company is in a strong position to pay its debts without incurring additional liabilities.
Operating Cash Flow Components
OCF consists of cash inflows and outflows related to a company's core business operations. Cash inflows typically include revenue paid in cash from sales of goods or services, collections of accounts receivable, other cash receipts from business operations, and refunds or reimbursements received.
Cash outflows generally comprise payments for inventory and raw materials, employee salaries, wages, and benefits, operating expenses like rent, utilities, and insurance, tax payments, and payments to suppliers and vendors.
Changes in working capital also significantly impact OCF. Working capital is the difference between current assets and current liabilities. For example, a decrease in accounts receivable (customers paying faster) increases OCF, while an increase in inventory (more cash tied up in goods) decreases OCF. An increase in accounts payable (delaying payments to suppliers) temporarily boosts OCF, and a decrease in accrued expenses (paying obligations sooner) reduces OCF.
Methods of Calculating Operating Cash Flow
There are two primary ways to calculate OCF: the indirect and direct methods.
Indirect Method
The indirect method starts with net income and adjusts for non-cash items and changes in working capital to arrive at OCF. This method is commonly used by companies in the U.S. Key adjustments include adding back non-cash expenses like depreciation and amortization, adjusting for changes in working capital accounts such as accounts receivable, inventory, and accounts payable, and removing non-operating gains or losses.
The basic formula for the indirect method is OCF = Net Income + Depreciation & Amortization - Changes in Net Working Capital. For example, if a company reports net income of $100 million, depreciation of $150 million, an increase in accounts receivable of $50 million, and a decrease in accounts payable of $50 million, the OCF would be $100M + $150M - $50M - $50M = $150M.
Direct Method
The direct method records all transactions on a cash basis, displaying actual cash inflows and outflows during the accounting period. While the Financial Accounting Standards Board (FASB) prefers this method for its clarity, it requires more work and is thus used less. The direct method accounts for cash received from customers, cash paid to suppliers and employees, interest and dividends received, and income taxes and interest paid.
The basic formula for the direct method is OCF = Cash Revenue - Operating Expenses Paid in Cash. For instance, if a company has cash receipts of $80 million, cash payments to suppliers of $25 million, and employee wages of $10 million, the OCF would be $80M - $25M - $10M = $45M. Both methods should yield the same result for OCF. The choice between them often depends on the company's accounting practices and the level of detail desired in financial reporting.
Example of Calculating Operating Cash Flow
Let's consider a small retail business with these variables: net income of $50,000, depreciation expense of $10,000 (a non-cash expense), increase in accounts receivable of $5,000 (customers owe more), increase in inventory of $3,000 (more inventory purchased), and increase in accounts payable of $8,000 (owed more to suppliers).
Here's how you calculate it: Start with net income: $50,000. Add back depreciation: + $10,000 (added because it's an expense without actual cash outflow). Subtract the increase in accounts receivable: - $5,000 (subtracted because increased receivables mean sales on credit, not cash). Subtract the increase in inventory: - $3,000 (subtracted because cash was spent on more goods). Add the increase in accounts payable: + $8,000 (added because the company held onto cash by delaying payments).
Result: $50,000 + $10,000 - $5,000 - $3,000 + $8,000 = $60,000 OCF.
The Bottom Line
OCF helps determine the financial success of a company's core business activities and indicates whether a company has enough positive cash flow to maintain operations. OCF is one of three cash flows listed on a company's statement of cash flows, the other two being investing activities and financing activities.
