What Is a P/S Calculator?

A PS calculator helps you compute the Price-to-Sales ratio, one of the fastest ways to compare valuation across stocks. The P/S ratio tells you how much investors are paying for each dollar of a company’s revenue.

Unlike earnings-based metrics, revenue is generally less affected by accounting choices, so P/S is often useful when evaluating younger companies, turnaround stories, or firms with low/negative earnings.

P/S Ratio Formula

The core formula is simple:

• P/S Ratio = Market Capitalization ÷ Annual Revenue

If you know per-share values, you can also use:

• P/S Ratio = Share Price ÷ Revenue Per Share

Quick Example

If a business has a market cap of $5 billion and annual revenue of $1 billion, the P/S ratio is 5.0. Investors are paying $5 for every $1 of annual sales.

How to Use This PS Calculator

• Enter market capitalization.
• Enter annual revenue.
• (Optional) Enter shares outstanding to see current share price and implied target price.
• (Optional) Enter a target P/S multiple to estimate fair-value market cap.

Once you click Calculate, the tool provides your current P/S ratio plus additional valuation insights.

How to Interpret P/S Results

Lower P/S

Can indicate a stock is undervalued, but may also signal weak growth, low margins, or business risk.

Higher P/S

Often reflects strong growth expectations, superior margins, or high-quality recurring revenue. It can also mean the stock is expensive if growth slows.

Sector Context Matters

A software company and a grocery chain should not be judged by identical P/S thresholds. Compare companies to peers with similar business models and margin structures.

When P/S Is Especially Useful

• Early-stage growth companies with low profits.
• Cyclical firms during temporary earnings dips.
• Cross-checking P/E and EV/EBITDA based valuations.
• Screening many stocks quickly before deeper analysis.

Limitations of the Price-to-Sales Ratio

• Ignores profitability: $1 of sales can be high-margin or low-margin.
• Ignores debt: Two firms with similar P/S may have very different balance-sheet risk.
• Can overvalue hype: High revenue growth does not always convert to free cash flow.

That’s why investors often pair P/S with gross margin trends, operating margin, free cash flow, and debt ratios.

Practical Tips for Better Analysis

• Compare current P/S to the company’s own 5-year history.
• Compare P/S against close industry peers.
• Use forward revenue estimates, not just trailing numbers.
• Stress-test your assumptions using different target P/S multiples.

FAQ

Is a low P/S always good?

No. A low P/S can be a bargain—or a warning sign about deteriorating demand, weak margins, or high debt.

What is a “good” P/S ratio?

There is no universal number. “Good” depends heavily on industry, growth rate, and profitability profile.

Can I use this calculator for target stock price?

Yes. Enter shares outstanding and a target P/S multiple to estimate implied market cap and implied share price.
