What is Intrinsic Value using EPS?
Calculating the intrinsic value using Earnings Per Share (EPS) is a method of stock valuation popularized by the legendary investor Benjamin Graham, Warren Buffett’s mentor. The goal is to determine the “true” underlying worth of a company’s stock based on its earnings power and growth prospects, independent of its current, often volatile, market price.
This approach allows investors to make rational decisions, aiming to buy stocks for less than their calculated intrinsic value, creating a “margin of safety.” It’s particularly useful for value investors who focus on a company’s fundamental financial health rather than market trends or speculation. The core idea is that a company’s value is directly tied to the profits it generates for its shareholders (EPS).
The Intrinsic Value Formula and Explanation
The most widely recognized formula for this calculation is Benjamin Graham’s revised formula, which accounts for both growth and prevailing interest rates.
Intrinsic Value (V) = [EPS × (8.5 + 2g) × 4.4] / Y
This formula provides a more robust estimate than simpler models by normalizing the value against the current return of safe investments (AAA corporate bonds). To learn more about valuation, consider reading about Discounted Cash Flow Analysis.
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| EPS | Earnings Per Share (Trailing Twelve Months) | Currency (e.g., $) | 0.10 – 50+ |
| g | Expected Annual Growth Rate | Percentage (%) | 0 – 20% |
| Y | Current Yield on AAA Corporate Bonds | Percentage (%) | 2% – 8% |
| 8.5 | The theoretical P/E ratio for a no-growth company. | Ratio (Unitless) | Constant |
| 4.4 | The average yield of AAA corporate bonds in 1962, when Graham developed the formula. | Percentage (%) | Constant |
Practical Examples
Example 1: Stable, Moderate-Growth Company
- Inputs:
- EPS: $5.00
- Expected Growth Rate (g): 6%
- AAA Bond Yield (Y): 4.5%
- Calculation: V = [$5.00 * (8.5 + 2*6) * 4.4] / 4.5 = [$5.00 * 20.5 * 4.4] / 4.5 = $451 / 4.5
- Result: The intrinsic value is approximately $100.22 per share.
Example 2: High-Growth Tech Company
- Inputs:
- EPS: $2.20
- Expected Growth Rate (g): 15%
- AAA Bond Yield (Y): 3.8%
- Calculation: V = [$2.20 * (8.5 + 2*15) * 4.4] / 3.8 = [$2.20 * 38.5 * 4.4] / 3.8 = $372.68 / 3.8
- Result: The intrinsic value is approximately $98.07 per share. This shows how a higher growth rate significantly impacts the valuation. For more on growth, see Earnings Growth Models.
How to Use This Intrinsic Value Calculator
- Enter Earnings Per Share (EPS): Find the TTM (Trailing Twelve Months) EPS from a reliable financial data source and enter it.
- Input Expected Growth Rate: Research analyst estimates or use your own judgment to determine a conservative annual growth rate for the next 7-10 years.
- Provide Bond Yield: Find the current yield for AAA-rated corporate bonds. This represents your opportunity cost in a very safe investment.
- Calculate and Analyze: Click “Calculate.” The tool will provide an estimated intrinsic value. Compare this value to the stock’s current market price. If the intrinsic value is significantly higher than the market price, the stock may be undervalued.
Interpreting the results requires context. A single number isn’t a buy signal; it’s a data point. Always perform further due diligence. You might also want to explore understanding P/E ratios to complement your analysis.
Key Factors That Affect Intrinsic Value
- Company Profitability: Higher and more consistent EPS directly increases the intrinsic value.
- Economic Moat: A strong competitive advantage can justify a higher expected growth rate (g).
- Interest Rate Environment: A higher bond yield (Y) increases the denominator in the formula, thus lowering the calculated intrinsic value. This is because safer investments offer better returns, making stocks comparatively less attractive.
- Industry Trends: A company in a declining industry may have a lower ‘g’ than one in a high-growth sector.
- Debt Levels: High debt can pose a risk to future earnings, potentially warranting a more conservative growth estimate.
- Management Competence: A strong leadership team is more likely to achieve projected growth rates. Explore our Management Scorecard Tool for deeper insights.
Frequently Asked Questions (FAQ)
- 1. Is this formula always accurate?
- No valuation formula is perfect. Intrinsic value is an estimate, not a certainty. The accuracy heavily depends on the quality of your inputs, especially the growth rate (g), which is a forecast.
- 2. Where can I find the data for the inputs?
- EPS data is widely available on financial websites like Yahoo Finance, Morningstar, or in a company’s quarterly/annual reports. AAA Corporate Bond Yields can be found on financial news sites or central bank websites.
- 3. Why use 8.5 as the base P/E?
- Benjamin Graham asserted that a company with zero earnings growth should trade at a P/E ratio of approximately 8.5. This serves as the foundation of the valuation before factoring in growth.
- 4. What is a good “margin of safety”?
- A common margin of safety is 20-30%. This means you would look to buy a stock when its market price is 20-30% below its calculated intrinsic value. This buffer helps protect against calculation errors and unforeseen negative events.
- 5. Can this be used for any company?
- This formula works best for stable, mature companies with predictable earnings. It may be less effective for startups with no current earnings, or for highly cyclical companies with volatile EPS.
- 6. How does the bond yield (Y) impact the value?
- The bond yield acts as a discount rate. When bond yields are high, the intrinsic value of stocks goes down because investors can get a good, safe return elsewhere. When yields are low, the intrinsic value of stocks tends to rise.
- 7. What if the calculated value is negative?
- A negative value can occur if a company has negative EPS. In this case, the Graham formula is not applicable, and other valuation methods like a Discounted Cash Flow (DCF) analysis might be more appropriate.
- 8. Why is the growth rate capped in some models?
- Sustaining very high growth rates is difficult. Many analysts cap the growth rate ‘g’ at 15% or 20% in the model to maintain a conservative and realistic valuation.
