Cash Flow Indicator Ratios: Operating Cash Flow/Sales Ratio
By Richard Loth (Contact  Biography)
This ratio, which is expressed as a percentage, compares a company's operating cash flow to its net sales or revenues, which gives investors an idea of the company's ability to turn sales into cash.
It would be worrisome to see a company's sales grow without a parallel growth in operating cash flow. Positive and negative changes in a company's terms of sale and/or the collection experience of its accounts receivable will show up in this indicator.
Formula:
Components:
As of December 31, 2005, with amounts expressed in millions, Zimmer Holdings had net cash provided by operating activities of $878.2 (cash flow statement), and net sales of $3,286.1 (income statement). By dividing, the equation gives us an operating cash flow/sales ratio of 26.7%, or approximately 27 cents of operating cash flow in every sales dollar.

None
Commentary:
The statement of cash flows has three distinct sections, each of which relates to an aspect of a company's cash flow activities  operations, investing and financing. In this ratio, we use the figure for operating cash flow, which is also variously described in financial reporting as simply "cash flow", "cash flow provided by operations", "cash flow from operating activities" and "net cash provided (used) by operating activities".
In the operating section of the cash flow statement, the net income figure is adjusted for noncash charges and increases/decreases in the working capital items in a company's current assets and liabilities. This reconciliation results in an operating cash flow figure, the foremost source of a company's cash generation (which is internally generated by its operating activities).
The greater the amount of operating cash flow, the better. There is no standard guideline for the operating cash flow/sales ratio, but obviously, the ability to generate consistent and/or improving percentage comparisons are positive investment qualities. In the case of Zimmer Holdings, the past three years reflect a healthy consistency in this ratio of 26.0%, 28.9% and 26.7% for FY 2003, 2004 and 2005, respectively.
