Investors are always looking for reliable ways to evaluate stock value. One essential metric used in fundamental analysis is the PEG Ratio—a financial indicator that enhances the popular Price-to-Earnings (P/E) Ratio by incorporating expected earnings growth. Our PEG Ratio Calculator simplifies this process, enabling users to assess whether a stock is fairly valued, overvalued, or undervalued based on its earnings growth rate.
Whether you’re a retail investor, financial analyst, or student studying finance, understanding and calculating the PEG Ratio is vital. This article will explore the PEG Ratio in-depth, explain how to use the tool, provide the formula in simple terms, showcase examples, and answer the 20 most frequently asked questions.
🔧 How to Use the PEG Ratio Calculator
Using this tool is extremely straightforward. Here’s how you can calculate the PEG Ratio step-by-step:
- Enter the Price-to-Earnings (P/E) Ratio of the stock.
- Enter the Earnings Per Share (EPS) Growth Rate in percentage.
- Click the Calculate button.
- The tool will instantly display the PEG Ratio based on your input.
Make sure both values are valid numbers, and the EPS Growth Rate is not zero, as dividing by zero will lead to invalid results.
✍️ PEG Ratio Formula Explained
The PEG Ratio is calculated by dividing the P/E Ratio by the Earnings Growth Rate.
Formula:
PEG Ratio = Price to Earnings Ratio / Earnings Per Share Growth Rate
- Price to Earnings Ratio is a company’s stock price divided by its earnings per share.
- Earnings Per Share Growth Rate is the expected annual growth rate of the company’s earnings, usually expressed in percentage.
👉 Note: If the earnings growth rate is expressed in percent, you don’t need to convert it into a decimal for this calculator.
🧠 Why Use the PEG Ratio?
The PEG Ratio is particularly useful because it:
- Offers a more complete valuation than the P/E ratio alone.
- Helps compare companies with different growth expectations.
- Indicates whether a stock is potentially undervalued or overvalued relative to its growth rate.
📊 Example Calculation
Let’s consider the following values:
- P/E Ratio: 20
- EPS Growth Rate: 10%
Using the formula:
PEG Ratio = 20 / 10 = 2.0
Interpretation:
A PEG Ratio of 2.0 may suggest that the stock is overvalued relative to its earnings growth, as many analysts consider a PEG around 1.0 to indicate fair value.

💡 Investment Insights from PEG Ratio
- PEG < 1: May indicate undervalued stock (potential buy opportunity).
- PEG = 1: Generally suggests the stock is fairly valued.
- PEG > 1: Could signal that the stock is overvalued.
However, it’s crucial to analyze the PEG Ratio in conjunction with other financial metrics and industry-specific factors. A low PEG might be justified in high-risk sectors, while a high PEG could be acceptable for extremely stable companies.
🧾 Common Use Cases

- Sector Analysis: PEG helps assess different sectors with varying growth trends.
- Long-term Investing: Ideal for evaluating growth potential over multiple years.
🔍 Additional Tips
- Always use forward-looking EPS growth estimates from credible sources for better accuracy.
- For cyclical industries, combine PEG with historical performance for context.
- PEG Ratio might not be reliable for companies with irregular earnings or negative growth.
