Valuation sits at the heart of finance, yet many find it intimidating. As someone who has spent years analyzing businesses, I know that valuation isn’t just about plugging numbers into formulas—it’s about understanding the story behind those numbers. In this article, I’ll break down the Price Method, one of the most widely used valuation techniques, and explain how it works in plain terms.

What Is the Price Method?
The Price Method is a valuation approach that determines the worth of an asset, business, or security by comparing it to similar entities in the market. Unlike intrinsic valuation methods like Discounted Cash Flow (DCF), the Price Method relies on market-driven metrics. The core idea is simple: if a comparable company trades at a certain multiple, a similar business should follow suit.
Key Price-Based Valuation Techniques
- Price-to-Earnings (P/E) Ratio
- Price-to-Book (P/B) Ratio
- Price-to-Sales (P/S) Ratio
- Enterprise Value-to-EBITDA (EV/EBITDA)
Each of these methods has strengths and weaknesses, which I’ll explore in detail.
The Price-to-Earnings (P/E) Ratio
The P/E ratio is perhaps the most famous valuation metric. It measures how much investors are willing to pay for each dollar of earnings. The formula is:
P/E = \frac{\text{Market Price per Share}}{\text{Earnings per Share (EPS)}}Example Calculation
Suppose Company A trades at $50 per share and has an EPS of $5. Its P/E ratio would be:
P/E = \frac{50}{5} = 10A P/E of 10 means investors pay $10 for every $1 of earnings. But is this cheap or expensive? That depends on the industry.
Interpreting P/E Ratios
| Industry | Average P/E (2023) |
|---|---|
| Technology | 25 |
| Healthcare | 18 |
| Utilities | 12 |
| Financials | 10 |
A tech stock with a P/E of 25 might be normal, but a utility stock at the same P/E could be overvalued. Context matters.
The Price-to-Book (P/B) Ratio
The P/B ratio compares a company’s market value to its book value (net assets minus liabilities). It’s useful for asset-heavy industries like banking.
P/B = \frac{\text{Market Price per Share}}{\text{Book Value per Share}}Example Calculation
If Company B has a share price of $30 and a book value per share of $20, its P/B is:
P/B = \frac{30}{20} = 1.5A P/B below 1 suggests the stock trades for less than its book value—potentially undervalued.
The Price-to-Sales (P/S) Ratio
For companies with erratic earnings, the P/S ratio can be a better measure. It compares market cap to total revenue.
P/S = \frac{\text{Market Price per Share}}{\text{Revenue per Share}}Example Calculation
Company C trades at $15 per share and generates $5 in revenue per share. Its P/S ratio is:
P/S = \frac{15}{5} = 3A P/S of 3 means investors pay $3 for every $1 of sales. This is common in high-growth sectors like SaaS.
Enterprise Value-to-EBITDA (EV/EBITDA)
EV/EBITDA is a broader metric, factoring in debt and cash. It’s useful for comparing firms with different capital structures.
EV/EBITDA = \frac{\text{Enterprise Value}}{\text{EBITDA}}Where:
\text{Enterprise Value} = \text{Market Cap} + \text{Debt} - \text{Cash}Example Calculation
Company D has:
- Market cap: $100M
- Debt: $20M
- Cash: $10M
- EBITDA: $15M
First, calculate EV:
EV = 100 + 20 - 10 = 110Then, EV/EBITDA:
EV/EBITDA = \frac{110}{15} \approx 7.33A ratio of 7.33 suggests the company is reasonably priced if peers trade at similar multiples.
Advantages of the Price Method
- Simplicity: Easy to calculate and interpret.
- Market-Based: Reflects real-time investor sentiment.
- Comparability: Helps benchmark against industry peers.
Limitations of the Price Method
- Dependent on Comps: Requires accurate comparable companies.
- Ignores Growth: Doesn’t account for future potential.
- Accounting Differences: Variations in reporting can skew ratios.
When to Use the Price Method
I prefer the Price Method when:
- The industry has clear, stable comparables.
- The company has consistent earnings (for P/E).
- I need a quick sanity check on valuation.
For early-stage startups or firms with negative earnings, I avoid it.
Final Thoughts
The Price Method isn’t perfect, but it’s a powerful tool when used correctly. By understanding the nuances of P/E, P/B, P/S, and EV/EBITDA, I can make more informed investment decisions. The key is to combine it with other methods—like DCF—for a complete picture.
