#### What is the Price to Sales (P/S) Ratio?

The Price to Sales Ratio is a method of evaluating a business based on the price of its stock and revenue.

The Price to Sales ratio can be calculated 2 ways; based on market cap and total revenue, or on a per share basis based share price and revenue per share.

First way, based on market cap and total revenue:

Second way, based on the company’s stock price and revenue per share:

Revenue per share is calculated by taking the total revenue and dividing by the number of shares outstanding (which is found on a company’s income statement).

For an example on calculating a company’s P/S ratio, lets look at Intel’s (INTC) 2011 10- k annual report, which can be found here:

At time of writing, Intel is trading at \$21.80 a share, with 5.4 billion shares outstanding (and therefore a market cap of about \$117 billion).

Market Cap ÷ Revenue = \$117 Billion ÷ \$54 billion = 2.16 Price to Sales Ratio

Or,

Share Price ÷ (Revenue ÷ Share Outstanding) = \$21.80 ÷ (\$54 Billion ÷ 5.4 billion shares) = 2.18 Price to Sales Ratio

(The small difference is due to rounding.)

Investors can then see that by purchasing Intel’s stock today they are paying about \$2.16 for each \$1 in sales. Investors can compare that ratio to Intel’s competitors to see if Intel’s stock is trading at a premium or a discount compared to their competitors stock.

The Price to Sales (P/S) ratio is preferred by some analysts over a Price to Earnings (P/E) ratio because earnings are easier for a company to “fudge” then sales. By looking at a company’s sales an investor can get a true picture of the outstanding demand for a company’s product.

Generally a lower P/S ratio indicates better value for investors. However it is important to note that investors should not base a decision to invest in a company solely on its P/S ratio. Investors need to take income and other figures into account before investing in a company.
