PEG Ratio Calculator (Price/Earnings to Growth)



The PEG Ratio Calculator (Price/Earnings to Growth) is a useful tool for assessing the relationship between a stock’s price, its earnings, and the expected growth over time.
This indicator combines the traditional P/E Ratio (price/earnings ratio) with the earnings growth rate, providing a more comprehensive and realistic view of a company’s value.

While the P/E Ratio alone shows how much investors pay for each euro of earnings, the PEG Ratio adds the growth dimension, helping to distinguish between genuinely promising companies and overvalued stocks.
The app is ideal for investors, financial analysts, advisors, and economics students who wish to enhance their analyses with a more refined and interpretive indicator.

How it works

The user inputs:

  • the P/E Ratio, calculated as the stock price divided by the EPS (earnings per share);
  • the expected growth rate (%), which is the estimated increase in earnings over the coming years.

The app automatically calculates the PEG Ratio, also providing a qualitative comment to help interpret the result based on average benchmark values.

Interpreting the results

  • PEG < 1 → The stock may be undervalued: the current price does not fully reflect its growth potential.
  • 1 ≤ PEG ≤ 2 → Balanced valuation, consistent with expected growth.
  • PEG > 2 → Possible overvaluation: the stock incorporates excessive or overly optimistic growth expectations.

Why it is useful

The PEG Ratio is a fundamental tool for those who wish to:

  • identify companies with sustainable growth potential, distinguishing them from inflated market stocks;
  • compare companies in the same sector based on a more accurate measure of real value;
  • balance valuation and growth, avoiding decisions based solely on price or current earnings;
  • dive deeper into the fundamental analysis of a stock quickly and reliably.

In summary, the PEG Ratio Calculator helps to determine whether a stock is overvalued, undervalued, or fairly priced, becoming an indispensable support for informed investment decisions.

Additional tools

The result is presented in a clear and organized container, with the option for quickly copying data to the clipboard, useful for inserting values into analysis reports, presentations, or comparisons between companies.
