What This Calculator Does
The Price-to-Sales Calculator divides a company's market capitalization by its annual revenue to produce the P/S ratio. This metric shows how much the market values each dollar of the company's sales. Enter the market cap and annual revenue to see the P/S ratio and understand how the company's valuation compares to its top-line performance.
Formula
Where:
- P/S = Price-to-Sales ratio
- Market Cap = Current share price × total shares outstanding
- Annual Revenue = Total revenue over the most recent trailing twelve months (TTM)
The P/S ratio can also be calculated per share by dividing the share price by revenue per share. Both methods produce the same result. TTM revenue is preferred over a single quarter to smooth out seasonal variations.
Input Fields Explained
Market Cap ($)
The total market value of the company's outstanding shares. This can be found on financial websites or calculated by multiplying the current share price by the number of shares outstanding.
Annual Revenue ($)
The company's total revenue over the trailing twelve months. Use the most recent full-year revenue or the sum of the last four quarters for the most accurate calculation. Make sure to use the same currency as the market cap.
Example Calculation
A company has a Market Cap of $5 billion and Annual Revenue of $2 billion.
P/S = 5,000,000,000 ÷ 2,000,000,000 = 2.5x
Interpretation: Investors are paying $2.50 for every dollar of the company's revenue. Whether this is reasonable depends on the industry, profit margins, and growth rate. High-margin software companies often trade at much higher P/S ratios than low-margin retailers with similar revenue.
How to Read the Result
The number of dollars of market value per dollar of revenue. A higher P/S means the market is paying more per unit of sales, which may reflect higher anticipated growth, better profit margins, or a premium brand. A lower P/S may suggest lower growth expectations or lower profitability — but no P/S level is inherently good or bad without context.
Common Mistakes
- Ignoring profit margin differences. Two companies with the same P/S ratio can have vastly different profitability. A 2% margin business needs much more revenue to generate the same earnings as a 20% margin business. Always consider margins alongside P/S.
- Comparing P/S across unrelated industries. Software companies often trade at 5-10x P/S, while retailers may trade at 0.3-0.8x. These differences reflect fundamentally different business models and margin structures, not relative cheapness.
- Assuming low P/S means undervalued. A low P/S ratio may reflect genuine problems — declining revenue, thin margins, competitive pressures, or structural challenges. It is a starting point for analysis, not a conclusion.
- Not accounting for revenue recognition policies. Different accounting treatments can inflate or deflate reported revenue, making P/S comparisons between companies with different policies unreliable.
- Forgetting that revenue does not equal cash flow. A company can have high revenue and still burn cash. P/S says nothing about whether the company is generating positive cash flow or profits.
When This Calculator Is Useful
- Valuing companies that are not yet profitable (startups, early-stage growth companies)
- Comparing revenue multiples within the same industry or sector
- Evaluating companies with volatile or negative earnings where P/E is not meaningful
- Screening stocks by revenue-based valuation as part of broader analysis
Limitations
- Does not reflect profitability — companies with the same P/S can have very different margins
- Ignores debt, capital structure, and cash flow
- Revenue recognition policies vary and can distort comparisons
- Not useful for financial companies where revenue is defined differently
- Does not account for growth rate differences between companies

Frequently Asked Questions
What is the price-to-sales ratio?
The price-to-sales (P/S) ratio divides a company's market capitalization by its annual revenue. It measures how much investors are paying for each dollar of the company's sales. Unlike earnings-based ratios, P/S uses revenue, which is less subject to accounting manipulation and is positive for most companies, even those that are not yet profitable.
How does P/S differ from P/E ratio?
The P/E ratio divides the stock price by earnings per share, while P/S divides market cap by total revenue. P/E is meaningless for companies with negative earnings, but P/S can still be calculated as long as the company has positive revenue. However, P/S ignores profitability entirely — a company with high revenue but no profits may look cheap on P/S but could be a poor investment.
What does a low P/S ratio mean?
A low P/S ratio means the market is valuing each dollar of revenue at a relatively low price. This could indicate that the company is attractively valued relative to its sales, or it could reflect concerns about low profit margins, declining growth, or business risks. A low P/S alone does not indicate undervaluation — it must be considered alongside profit margins, growth trends, and industry context.
Why use P/S for unprofitable companies?
When a company is not yet profitable, P/E and other earnings-based ratios cannot be calculated because earnings are negative. P/S provides a way to value these companies based on their revenue, which is typically positive. This makes it useful for early-stage companies, startups, and turnaround situations where profitability may not yet be achieved but revenue growth is meaningful.
What are the limitations of P/S ratio?
P/S ignores profitability, so two companies with the same P/S ratio can have very different bottom-line results. A company with a 2% profit margin and one with a 20% margin should not trade at the same P/S. P/S also does not account for debt, capital structure, or cash flow. It is less useful for financial companies where revenue is defined differently from operating businesses.
How does revenue recognition affect P/S?
Companies can recognize revenue differently depending on their accounting policies and business models. A software company booking multi-year contracts upfront will show different revenue patterns than one recognizing revenue monthly. Revenue recognition choices, currency effects, and the mix of organic vs. acquisition-driven growth can all distort P/S comparisons between companies.
