Price-to-Sales Calculator

The price-to-sales ratio compares a company's market capitalization to its annual revenue. It tells you how much the market is paying for each dollar of revenue. A P/S of 3× means investors are paying $3 for every $1 of annual revenue. P/S is particularly useful for companies that are not yet profitable — where P/E is meaningless — because revenue is always positive.

P/S = Market Capitalization ÷ Annual Revenue (TTM). Alternatively: P/S = Stock Price ÷ Revenue Per Share. For example, a company with a $5B market cap and $2B in trailing twelve-month revenue has a P/S of 2.5×. You can also start from per-share data: if the stock trades at $50 and revenue per share is $20, P/S = 50 ÷ 20 = 2.5×.

It depends entirely on the sector and the company's margin profile. High-margin SaaS businesses routinely trade at 8–20× P/S because each dollar of revenue converts efficiently to profit. Low-margin retailers trade at 0.3–1.0× because margins are thin. A P/S ratio is only meaningful compared to sector peers with similar margin structures.

Early-stage growth companies — particularly in technology and biotech — often invest heavily in growth at the expense of near-term profitability. P/E is undefined or negative for these companies, making it useless. P/S provides a relative valuation anchor even when earnings are absent. However, it must be paired with revenue growth rate and gross margin to assess whether the multiple is justified.

P/S ignores profitability. A company with 5% net margins and a 5× P/S trades at a very different intrinsic value than a company with 40% net margins at the same multiple. High revenue growth can justify a high P/S, but only if that growth eventually converts to meaningful earnings. P/S alone cannot distinguish between a genuinely undervalued business and a high-revenue, low-profit company with structural margin problems.

P/S and net profit margin are directly linked through the P/E ratio: P/S = P/E × Net Margin. If you expect a business to eventually achieve a 20% net margin and trade at 25× earnings, the implied P/S is 5× (25 × 0.20). This relationship helps assess whether a current P/S is reasonable given the margin trajectory the market is implicitly pricing in.

Equity Rank incorporates price-to-sales into its multi-method valuation consensus, with sector-adjusted weighting. For high-growth, pre-profitable technology and biotech companies, P/S receives more weight in the consensus. For capital-heavy industrials and energy companies where margins are thin, EV/EBITDA and cash flow multiples receive more emphasis. The result is a composite fair value estimate calibrated to the company type.
