The price-to-sales ratio is an essential valuation metric, especially for evaluating growth companies that aren't yet profitable. Pioneered by Kenneth Fisher in his 1984 book 'Super Stocks,' P/S became a key tool during the dot-com era and remains crucial for SaaS and tech valuations. The S&P 500 average P/S is approximately 2.8x, but the range spans from 0.2x for grocery chains to 20x+ for high-growth SaaS.

Key Takeaways
- • P/S = Market Cap / Annual Revenue, or P/S = Stock Price / Revenue Per Share
- • P/S < 1.0 is considered a bargain; P/S > 10 is expensive unless growth justifies it
- • P/S works for unprofitable companies where P/E doesn't apply (startups, biotech)
- • The Rule of 40 (growth + margin > 40%) helps assess if a high P/S is justified
Did You Know?
How Does the P/S Ratio Work?
Market Cap Method
P/S = Market Cap / Annual Revenue. Market cap = Stock Price × Shares Outstanding. This compares total market value to total sales.
Per-Share Method
P/S = Stock Price / Revenue Per Share. Revenue Per Share = Annual Revenue / Shares Outstanding. Both methods yield the same result.
Sector Context
Retail: 0.5-2x. SaaS: 5-15x. Healthcare: 3-6x. Auto: 0.3-0.8x. Always compare within the same industry; cross-sector P/S comparisons are misleading.
Expert Tips
P/S by Sector (Typical Ranges)
| Sector | Typical P/S | Notes |
|---|---|---|
| Retail | 0.5-2 | Thin margins |
| SaaS | 5-15 | Recurring revenue |
| Healthcare | 3-6 | IP and R&D |
| Auto | 0.3-0.8 | Capital-intensive |
| Industrial | 1-2 | Moderate growth |
Frequently Asked Questions
What is the price-to-sales ratio?
P/S ratio compares a company's stock price to its revenue per share. P/S = Market Cap / Revenue. It's useful for valuing unprofitable companies where P/E doesn't work.
What is a good P/S ratio?
Varies by industry. Retail: 0.5-2x. SaaS: 5-15x. Healthcare: 3-6x. Generally, P/S < 1.0 is considered a bargain. P/S > 10 is very expensive unless growth justifies it.
Why use P/S instead of P/E?
P/S works for unprofitable companies (many startups, biotech). Revenue is harder to manipulate than earnings and less volatile. It's popular for high-growth companies not yet profitable.
How does P/S compare to EV/Sales?
P/S uses market cap (ignores debt/cash). EV/Sales uses enterprise value (market cap + debt - cash), making it more comprehensive for comparing companies with different capital structures.
What sectors have the lowest P/S ratios?
Grocery/retail (0.2-0.5x), auto manufacturers (0.3-0.8x), and commodity businesses have low P/S due to thin margins. High P/S indicates the market expects high future margins.
How does revenue growth affect P/S?
Companies growing 30%+ often trade at P/S of 10-20x. Slow-growth (<10%) typically trades at 1-3x. The Rule of 40 (growth + margin > 40%) helps assess if a high P/S is justified.
