What the price-to-sales ratio is
The price-to-sales ratio divides a company's total market value by its annual revenue, or equivalently its share price by its sales per share. It tells you how much investors are paying for each dollar of sales the company generates.
Because almost every company has revenue, even ones that are not yet profitable, the price-to-sales ratio can be calculated when an earnings-based ratio cannot. That makes it a popular tool for valuing fast-growing or early-stage businesses.
When it is most useful
The price-to-sales ratio comes into its own when a company has little or no profit. A young growth company reinvesting everything, or a cyclical business in a downturn, may show no earnings, which makes price-to-earnings meaningless. Revenue is steadier and harder to wipe out, so price-to-sales still gives a reference point.
It is also useful as a quick first screen, because revenue is harder to manipulate with accounting choices than profit is.
💡 Margins change everything:A dollar of sales at a high-margin software firm is worth far more than a dollar of sales at a low-margin retailer. That is why a high price-to-sales ratio can be perfectly reasonable in some industries and alarming in others.
How to read it
A lower price-to-sales ratio suggests you are paying less for each dollar of revenue, and a higher one suggests the market expects strong future growth or fat profit margins. The reasonable range varies enormously by industry, so the number means little on its own.
Comparing a company with its own history and with close competitors is far more informative than judging it against a universal benchmark.
What it leaves out
The big weakness of price-to-sales is that it ignores profitability entirely. A company can have enormous revenue and still lose money on every sale, and the ratio would not show it. Two firms with the same price-to-sales ratio can be worlds apart if one keeps far more of each sale as profit.
It also ignores debt. For that reason, price-to-sales is best used as one lens among several, paired with a look at margins and the balance sheet.
Frequently asked questions
What is a good price-to-sales ratio?
It depends heavily on the industry and the company’s profit margins. High-margin software companies routinely carry much higher ratios than low-margin retailers, so there is no universal good number. Comparing to peers and to the company’s own history is more useful.
When should I use price-to-sales instead of price-to-earnings?
Price-to-sales is most useful when a company has little or no profit, such as a young growth business or a cyclical company in a downturn, where price-to-earnings cannot be calculated. It gives a valuation reference point when earnings are absent or distorted.
Does the price-to-sales ratio account for profit?
No. It looks only at revenue, not at how much of that revenue becomes profit. A company can have a low ratio and still lose money on every sale, which is the main limitation of the measure. It should be paired with a look at margins.
Why does price-to-sales vary so much by industry?
Because profit margins differ. A dollar of sales is worth more at a high-margin business than at a low-margin one, so investors pay more per dollar of revenue for companies that keep more of each sale. That is why software trades higher than retail.
