Price to Sales Ratio Calculator: P/S From Market Cap and Revenue
Work out a stock's price-to-sales ratio — the valuation metric that makes sense for companies with negligible or volatile earnings, where the P/E ratio either does not exist or misleads.

Compare Common Scenarios
How the numbers shift across typical situations for this calculator:
| Scenario | P/S ratio (market cap per $1 of revenue) |
|---|---|
| $5B / $1B revenue | $5.00 |
| $200M / $40M revenue | $5.00 |
| $50B / $20B revenue | $2.50 |
| $800M / $1.2B revenue (sub-1) | $0.67 |
How This Calculator Works
Enter market capitalization and annual revenue. The calculator divides one by the other to give the P/S ratio — read as 'dollars of market cap per dollar of revenue'.
The Formula
Cost per Unit
Total Amount is the full cost or price, Quantity is the number of units it covers
Worked Example
A $5B market cap company on $1B of revenue trades at a 5x P/S ratio. Software and high-growth tech often trade above 5x; retail and traditional industry typically run 0.5x to 2x; commodity businesses often below 1x. The S&P 500 has averaged a P/S around 1.5x to 2.5x across decades.
Key Insight
P/S is the right valuation lens for three situations: pre-profitability tech, cyclicals at the trough of earnings, and turnarounds where earnings are temporarily distorted. The trade-off is that revenue tells you nothing about margin — a 5x P/S can be expensive on a 5%-margin business and cheap on a 30%-margin one. Always pair P/S with gross margin or operating margin context.
Why software P/S is 10× retail P/S — gross margin and growth
P/S correlates strongly with gross margin and revenue growth. A software company with 80% gross margin generates $0.80 of contribution margin per dollar of revenue; a retailer with 25% gross margin generates $0.25. The 'value per dollar of revenue' differs by 3×, justifying meaningfully different P/S multiples.
Add growth — a software company growing 30% annually generates faster cash flow growth than a retailer growing 3%. Combining margin and growth: an 80%-margin / 30%-growth SaaS company at 10× P/S is similar in implied valuation to a 25%-margin / 3%-growth retailer at 0.8× P/S. The cross-sector P/S comparison only makes sense after these adjustments.
For SaaS specifically, Bessemer's State of the Cloud tracks public SaaS company P/S quartiles by growth rate. 2024 medians: <20% growth: 4× P/S; 20-30%: 7×; 30-40%: 10×; 40-50%: 14×; 50%+: 18×+. The relationship is approximately linear in mature markets — investors pay premium multiples for fast-growing SaaS even at higher absolute prices.
When P/S is misleading — quality of revenue matters
Two companies with identical P/S can be very different value propositions if their revenue quality differs. (1) RECURRING vs TRANSACTIONAL — a subscription SaaS company with 95% recurring revenue is worth more per dollar of revenue than a transactional company with the same revenue but 0% recurring; (2) HIGH-MARGIN vs LOW-MARGIN — already discussed; (3) DIVERSIFIED vs CONCENTRATED — a company with 1,000 customers is more valuable than one with 5 customers each contributing 20% of revenue (concentration risk).
(4) ORGANIC vs ACQUIRED — organic revenue growth is more valuable than acquired revenue growth because it suggests sustainable competitive advantage; companies growing via acquisition often trade at lower P/S because the growth requires continued M&A which is hard to maintain; (5) GROWTH SUSTAINABILITY — a SaaS company at 50% growth showing decelerating quarter-over-quarter sequential growth is in a different valuation position than one with re-accelerating growth.
For honest valuation: never use P/S alone. Pair with growth rate (PEG-equivalent for revenue), gross margin (quality of incremental revenue), customer concentration (revenue durability), and Rule of 40 (growth + EBITDA margin). The composite picture is what drives SaaS valuation in private and public markets.
P/S benchmarks by U.S. sector (Damodaran 2024)
Reference P/S ratios by sector. Cross-sector comparison without margin / growth adjustment is misleading.
| Sector | Median P/S | Median gross margin | Notes |
|---|---|---|---|
| Software (Internet / SaaS) | 8-12 | ~75% | Growth premium |
| Tobacco | ~5 | ~67% | Brand premium |
| Pharma (Branded) | ~4 | ~74% | |
| Beverage (Alcohol) | ~3.5 | ~55% | |
| S&P 500 (overall) | ~2.7 | ~46% | |
| Healthcare Services | ~1.0 | ~32% | |
| Retail (General) | ~0.7 | ~30% | Low-margin |
| Banks (excluded — no revenue concept) | n/a | n/a | Use NIM-based metrics |
| Industrials (heavy) | ~1.2 | ~25% | |
| Auto Manufacturing | ~0.5 | ~16% | Low-margin |
| Grocery | ~0.3 | ~26% | Razor-thin margins |
| Trucking | ~0.5 | ~9% |
P/S correlates strongly with gross margin and growth rate. The cross-sector P/S spread (8-12× software vs 0.3× grocery) reflects 4-30× differences in dollar of profit per dollar of revenue. Within sectors, P/S spreads reflect growth differentials — fast-growing SaaS trades at 18×+, mature SaaS at 4-6×.
Frequently Asked Questions
How is P/S ratio calculated?
Divide market capitalization by annual revenue (trailing twelve months). A $5B market cap on $1B of revenue is a 5x P/S ratio.
When is P/S better than P/E?
When earnings are negligible (pre-profitability growth), volatile (cyclical businesses), or temporarily distorted (turnarounds, restructuring). Revenue is more stable than earnings, which makes P/S more interpretable in those situations.
What is a good P/S ratio?
Varies by industry. Software and high-growth tech often 5x to 20x. Retail and consumer 0.5x to 2x. Commodity industries below 1x. Always benchmark against industry peers, not market averages.
What does P/S miss?
Margin. Two companies on the same P/S can be very different businesses if one runs a 30% operating margin and the other a 5%. Pair P/S with margin context — high margins justify high P/S; low margins do not.
Does P/S work for banks and financials?
Less well. Banks earn from net interest margin and non-interest revenue; the revenue line is structured differently from operating businesses. Price-to-book and ROE are more common for financial-sector valuation.
When is this calculator unreliable?
For companies with very different gross margins or growth rates (cross-sector P/S comparison is misleading without normalization), when revenue is volatile or distorted by acquisitions / one-time items (use trailing 4-quarter sum or normalized estimate), or when revenue includes pass-through items that aren't really 'value-creating revenue' (e.g., gross-revenue vs net-revenue reporting in payments, advertising tech).

Methodology & Review
Price-to-sales ratio (P/S) equals market capitalization / total revenue (or stock price / revenue per share). The calculator returns the P/S ratio. P/S is most useful for companies with negative or low earnings where P/E breaks down — particularly high-growth tech, biotech, venture-stage companies. U.S. average P/S: ~2.5 for S&P 500; high-margin software 5-15; commodity / low-margin businesses 0.3-1.0. P/S correlates with gross margin (high-margin businesses can sustainably support higher P/S multiples). RELIABILITY: Reliable for revenue comparison across companies with different earnings characteristics. Less reliable for companies with very different gross margins (a 10× P/S for an 85%-margin software company is similar to 1× P/S for a 30%-margin retailer in implied valuation), when revenue is volatile or unusual (commodities, M&A activity), or when comparing across business models (a subscription SaaS company with predictable revenue warrants higher P/S than a transaction-driven retailer with the same dollar revenue).
