What Is Operating Cash Flow?
Operating Cash Flow (OCF) shows how much cash a company’s normal business activities generate, separate from investing or financing activities. It’s a key indicator of whether a business can sustain and grow operations without relying on outside funding.
The Formula
OCF = Operating Income − Taxes + Depreciation & Amortization − Increase in Working Capital. Depreciation is added back because it’s a non-cash expense, while a rise in working capital (more tied up in receivables or inventory) reduces available cash.
- A positive, growing OCF generally signals healthy operations.
- OCF can differ significantly from net income due to non-cash items and timing of cash receipts/payments.
