Price to Sales (P/S) Calculator

P/S values a company against its sales — useful when earnings are negative.

How the Math Works

The Price to Sales (P/S) ratio is calculated by dividing a company's market capitalization by its total revenue over a specific period. Market capitalization represents the total value of a company's outstanding shares (calculated as share price multiplied by shares outstanding), while revenue is the total income generated from sales of goods or services. This ratio provides a snapshot of how much investors are paying for each dollar of sales the company generates. A higher P/S ratio suggests investors expect strong future growth, while a lower ratio may indicate the stock is undervalued relative to its sales performance.

Practical Applications

Investors use the P/S ratio to compare companies within the same industry, as it helps identify potential buying opportunities. A company with a lower P/S ratio might be undervalued compared to peers, especially if its sales growth prospects are similar. This metric is particularly useful for evaluating companies with volatile or negative earnings, where the Price to Earnings (P/E) ratio would be less meaningful. Analysts also track P/S ratios over time to assess whether a company's valuation is aligning with its sales trajectory or diverging from it.

Day-to-Day Use

For individual investors, the P/S ratio simplifies the process of screening stocks during portfolio management. It helps avoid companies that are overhyped relative to their sales, which can prevent overinvestment in speculative ventures. Additionally, this ratio aids in setting realistic expectations for stock performance—investors can gauge whether a company's market valuation is justified by its current revenue and decide if it's a good time to buy or sell. By focusing on sales rather than profits, the P/S ratio also provides insights into businesses with high reinvestment needs or cyclical earnings patterns.

Worked example

$5M cap ÷ $2.5M revenue → 2.0.
