The way to calculate the OCF is by dividing your operating expenses by current liabilities. OCF is the cash generated by a company’s operating activities, while current liabilities include accounts payable and other debts that are due within one year or less. Operating Cash Flow takes this into account with information from your statement of cash flows rather than relying on Income Statement & Balance Sheet which would be impacted by non-cash expenses such as depreciation charges for assets used in operations over time. The formula for OCF is: Operating cash flow ratio = Operating cash flow / Current liabilities
