Financial Statement Basics

Operating Cash Flow (OCF)

Operating Cash Flow

At a glance

The cash a company actually brought in from running its main business — real money received, not book profit.

OCF = the sum of cash that came in and went out from the main business (operating activities)

If OCF is steadily positive and similar to or larger than net income, cash generation is healthy.

In plain terms

The "profit" on the income statement includes things like credit sales, where the cash hasn't come in yet. Operating cash flow (OCF) strips away that accounting treatment and looks only at the cash that actually moved in and out of the bank account from running the main business.

So it's the starting point for seeing how different "book profit" and "real cash" are.

What it tells you

It shows whether the company is really earning cash from its main business. If book profit is positive but OCF is weak, it's a signal to consider whether profit is tied up in receivables or inventory instead of coming in as cash.

It's also the starting point for free cash flow (FCF) — subtract capital expenditures (CapEx) from OCF and you get FCF.

Formula

OCF = the sum of cash that came in and went out from the main business (operating activities)
(the operating activities section of the cash flow statement)

What high or low means

If OCF is steadily positive and similar to or larger than net income, cash generation is healthy.

If it is far smaller than net income or negative, it means profit isn't translating into cash well, which is a sign of low earnings quality.

Caution

OCF can swing from quarter to quarter due to temporary changes in working capital (receivables, inventory, etc.). It shows up better across several quarters than in a single one.

Even with strong OCF, if capital expenditures (CapEx) are larger, the cash actually left over (FCF) can be negative. Looking at it together with CapEx shows the real spare cash.

Metrics to read alongside

FCF (Free Cash Flow)

Subtracting capital expenditures (CapEx) from operating cash flow (OCF) gives free cash flow (FCF). Viewing the two together shows how much of the cash earned actually remains.

FCF Conversion

OCF is the starting point for seeing how much of book profit arrives as cash. Viewed together with the FCF conversion rate, it gives a sense of earnings quality.

Net Margin

Looking at net margin (book profit) and operating cash flow (actual cash) together lets you check whether that profit is really landing in the bank account.
