About Price to Revenue (P/S) Calculator

How the P/S Ratio Is Calculated

The formula is: P/S Ratio = Market Cap / Annual Revenue. At the per-share level: P/S = Share Price / Revenue Per Share. Both methods produce the same result. A company with a $10 billion market cap and $2 billion in annual revenue has a P/S of 5.0x, meaning investors pay $5 for every $1 of revenue the business generates.

Worked example: Suppose a company trades at $45 per share and reports $5 in revenue per share (trailing twelve months). The P/S ratio is $45 / $5 = 9.0x. The revenue yield - the inverse of P/S - is ($5 / $45) x 100 = 11.1%. If that company has a gross margin of 65%, the price-to-gross-profit ratio is $45 / ($5 x 0.65) = 13.8x. The gross-profit-adjusted multiple is always higher than the raw P/S because gross profit is a subset of total revenue.

This calculator computes P/S ratio, revenue yield, price-to-gross-profit (when you enter a margin), and the implied revenue figure needed to hit a target P/S multiple you specify.

What Is a Good P/S Ratio?

There is no single "good" number. P/S ratios vary enormously by industry because profit margins and growth rates differ so much. A SaaS company with 80% gross margins and 30% annual growth commands a far higher revenue multiple than a grocery retailer running on 2% net margins.

As of January 2026, the S&P 500's overall P/S ratio sits around 3.2x, according to data from Multpl.com and GuruFocus. That is well above the historical median of roughly 1.6x (going back to 1999), and close to the dot-com peak of about 3.4x reached in December 1999. NYU professor Aswath Damodaran publishes detailed P/S data by industry each January. His January 2026 dataset (pages.stern.nyu.edu) shows enormous variation across sectors.

Sector	Typical P/S Range	Why
SaaS / Cloud Software	8 - 15x	High margins (70-85%), recurring revenue, scalable
Biotechnology	5 - 12x	Pre-revenue pipeline valued on potential
Tech (Hardware)	4 - 10x	Moderate margins, product cycles
Healthcare	3 - 8x	Regulated, stable demand, moderate margins
Financial Services	2 - 5x	Revenue includes interest income (different economics)
Consumer Goods	1 - 3x	Lower margins, competition on price
Retail	0.5 - 2x	Razor-thin net margins (1-3%)
Energy	0.5 - 2x	Cyclical, commodity-driven revenue
Food Wholesale / Grocery	0.2 - 0.5x	Extremely thin margins (1-2%)

The key insight is that P/S alone does not tell you whether a stock is cheap or expensive. A 10x P/S might be cheap for a fast-growing cloud company but wildly expensive for a retailer. Always compare within the same industry and consider the company's margin profile.

When to Use P/S Over PE Ratio

The price-to-earnings (PE) ratio is the most common valuation multiple, but it breaks down when a company has no earnings. Many high-growth companies are unprofitable during their expansion phase - they reinvest every dollar into growth, producing negative net income. That makes PE either negative or undefined.

P/S solves this problem because every operating company has revenue, even when it has no profit. Revenue is also harder to manipulate than earnings. Earnings can be shifted by changes in depreciation schedules, one-off write-downs, stock-based compensation treatment, and other accounting choices. Revenue recognition is more standardised under IFRS 15 and ASC 606, making P/S a cleaner signal in some respects.

That said, P/S has a major blind spot: it ignores costs entirely. A company burning through cash with unsustainable unit economics can look cheap on a P/S basis while actually being a poor investment. That is why many analysts prefer EV/Revenue over P/S for more rigorous analysis.

P/S Ratio vs EV/Revenue - Which Is Better?

The enterprise value (EV) to revenue ratio is widely considered the superior metric. The difference comes down to what is in the numerator. P/S uses market capitalisation (equity value only), while EV/Revenue uses enterprise value (market cap plus net debt). This matters because debt holders also have a claim on the company's revenue.

Consider two companies with identical $1 billion revenue. Company A has a $5 billion market cap and no debt (P/S = 5.0x, EV/Revenue = 5.0x). Company B also has a $5 billion market cap but carries $3 billion in debt (P/S = 5.0x, EV/Revenue = 8.0x). The P/S ratio says they are valued identically, but Company B is actually valued much higher when you account for the debt that also needs to be serviced from that same revenue stream. EV/Revenue catches this. In M&A contexts, acquirers always think in terms of EV/Revenue because they are buying the whole business, debt included.

Use P/S for quick screening and rough comparisons. Switch to EV/Revenue for any serious valuation work, especially when comparing companies with different capital structures.

Revenue Yield - The Inverse of P/S

Revenue yield flips the P/S ratio to show how much revenue a company generates per dollar of market value. If P/S is 5.0x, the revenue yield is 20% - the company generates $0.20 in revenue for every $1 of market cap. This framing can be more intuitive when comparing across companies. A higher revenue yield means you are getting more revenue per dollar invested. It functions similarly to how the dividend yield shows income return, but using total revenue instead of dividends.

Price-to-Gross-Profit - Adjusting for Margins

One major limitation of P/S is that it treats all revenue as equal, regardless of how much the company keeps after cost of goods sold. A company with 80% gross margins keeps $0.80 of every revenue dollar for operating expenses and profit, while a company with 20% gross margins keeps just $0.20. Comparing these two on raw P/S is misleading.

Price-to-gross-profit adjusts for this by dividing market cap (or share price) by gross profit instead of revenue. The formula is: P/GP = Price / (Revenue x Gross Margin). Enter a gross margin percentage in this calculator to see the adjusted ratio. This metric provides a more level comparison between companies with different cost structures within the same sector.

Common Mistakes When Using P/S

The most common error is comparing P/S ratios across different industries. A 2x P/S in retail means something completely different from 2x in software. Always compare within the same sector.

Another frequent mistake is ignoring revenue quality. Recurring subscription revenue is worth more than one-time project revenue, even if the total is the same. A SaaS company with $100 million in annual recurring revenue (ARR) will trade at a higher multiple than a consulting firm with $100 million in project-based revenue, because the SaaS revenue is more predictable and has higher retention rates.

Watch out for companies that inflate revenue through aggressive practices like channel stuffing (shipping excess inventory to distributors) or premature revenue recognition. While revenue is harder to manipulate than earnings, it is not immune. Always check whether revenue growth is matched by corresponding cash flow growth - if revenue rises sharply while operating cash flow stays flat or declines, that is a warning sign.

Finally, remember that P/S is a snapshot. A company's trailing twelve-month revenue might not reflect its current run rate. Fast-growing companies often trade on forward revenue estimates, which makes their trailing P/S look inflated. Analysts typically calculate both trailing and forward P/S to get the full picture.

Historical P/S Trends for the S&P 500

The S&P 500's aggregate P/S ratio has ranged from a low of about 0.65x (during the 2008-2009 financial crisis) to a high of roughly 3.4x (at the peak of the dot-com bubble in late 1999). The long-term median sits around 1.6x. As of early 2026, the ratio is approximately 3.2x according to Multpl.com, placing it near the 99th percentile historically and roughly 2.5 standard deviations above its long-run average.

This elevated level does not necessarily mean the market is about to crash. The composition of the S&P 500 has shifted heavily toward technology and healthcare companies that naturally command higher revenue multiples. In 2000, tech represented about 20% of the index by weight. By 2026, it accounts for roughly 30%. Since higher-margin sectors now make up a larger share of the index, a structurally higher P/S than the historical average is partly justified - but how much higher is a constant debate among market strategists.

Using P/S in Practice

A practical approach to using the P/S ratio involves three steps. First, identify the sector median P/S for the company you are analysing. Damodaran's dataset (updated each January at NYU Stern) is the standard reference. Second, compare the company's P/S to that sector median. If it is trading significantly above the median, the market is pricing in faster growth or better margins than the peer group. If below, the market expects weaker performance or perceives higher risk. Third, check whether the premium or discount is justified by looking at the company's revenue growth rate, gross margin trajectory, and competitive position.

For example, if the software sector median P/S is 8.0x and a particular company trades at 12.0x, ask why. If it is growing revenue at 40% annually while peers average 20%, the premium is reasonable. If growth has slowed to 15% and margins are compressing, the premium may not hold up. Combining P/S with the compound growth rate (CAGR) calculator helps quantify historical revenue growth trends for comparison.

Screening for low P/S stocks relative to their sector can surface value opportunities, but always investigate further. A low P/S might reflect a genuine bargain, or it might reflect deteriorating fundamentals that the market is pricing in correctly.
