Inputs
Market capitalization
Also called: Market cap, MVE (market value of equity)
Where to find it: Shown prominently on any stock overview page.
How to derive: Share price × shares outstanding.
Revenue
Also called: Sales, turnover, top line
Where to find it: Income statement, very first line.
How to derive: Units sold × price; stated directly in the income statement.
Margin
Also called: Profit margin (gross/net)
Where to find it: Income statement: respective profit ÷ revenue.
How to derive: Gross margin = gross profit ÷ revenue; net margin = net income ÷ revenue.
Result, live
P/S only means something with margin context: P/S 2 at a 20% margin = P/E 10; at a 2% margin = P/E 100.
The price-to-sales ratio (P/S) compares the market value of a company to its annual revenue — the one multiple that still works when profits are thin or negative. This calculator divides market cap by sales in seconds and, if you add a net margin, shows the P/E those sales would imply.
How the formula works
Divide the whole market capitalization by yearly revenue and you get the P/S ratio. Because it ignores costs, a thin margin needs a low P/S to be cheap — so the calculator also turns sales into an implied P/E using the margin you enter.
Implied P/E = market cap ÷ (revenue × net margin)
Example: A company worth $5,000m earns $2,500m in revenue at an 8% net margin. P/S = 5,000 ÷ 2,500 = 2.0. The same sales imply a P/E of 25 — average revenue value, but a rich earnings multiple because the margin is thin.
How to read the result
- Below 1.5 — cheap relative to revenue, especially if margins are healthy.
- 1.5 to 4 — the average range for most companies.
- Above 4 — a rich revenue multiple; only fast growth or fat margins justify it.
What to watch out for
- Margins decide everything. P/S 2 at a 20% margin is a P/E of 10; at a 2% margin it is a P/E of 100.
- Revenue is not profit. Growing sales that never turn into cash can still destroy value.
- Compare within a sector. Software carries far higher P/S than retail.
P/S ratio by sector
A P/S ratio only means something next to the company's own sector: high-margin software trades at a multiple of sales, thin-margin retail far below it. The table shows median and range for every sector from our database, updated daily.
