What is cash flow from operations?
Cash flow from operations is the cash a business generates from its normal operations in a period, before capital spending and financing. It is the first section of the cash flow statement. Most companies show it by starting from net income, adding back non-cash charges such as depreciation, then adjusting for changes in receivables, inventory and payables.
Why it matters to a revenue leader
This is the number that tells you whether the business funds itself. A services company can grow revenue and profit while operating cash flow falls, because receivables grow faster than collections. Sponsors and lenders watch it closely, since debt is repaid in cash. A revenue leader affects it through payment terms, deposits, billing frequency and how quickly invoices go out after the work is done.
How to calculate it
Cash flow from operations = net income + non-cash expenses (such as depreciation and amortization) minus increases in working capital, or plus decreases. A common mistake is assuming strong profit means strong cash, when rising receivables can absorb most of it.
Example
Fictitious numbersAn environmental services company earns $3 million of net income and records $1 million of depreciation. Receivables grow $2.5 million as it adds large industrial customers on 60-day terms. Cash flow from operations is $1.5 million, half of reported net income.
