Calculate fair value of any stock

Calculating the fair value of a stock is akin to an archaeological dig, unearthing its intrinsic worth. Unlike the shifting sands of market sentiment or the capriciousness of short-term market fluctuations, fair value is firmly anchored in methodical analysis and rationality. This crucial metric serves as a beacon for investors, offering clarity on whether a stock is presently undervalued, overvalued, or sitting just right.

Our journey through this comprehensive guide will lead us to unravel the intricacies of stock valuation. It matters not whether you're a newcomer to investing, eager to establish a solid foundation, or a seasoned trader seeking to hone your skills—this post is crafted to cater to all.

We will navigate through the intricacies of various methodologies, tools, and factors that contribute to fair value calculations. Our mission: to empower you with the knowledge and insights needed to make well-informed investment decisions.

Understanding Fair Value Calculations

Multi-Stage DDM Calculator for Stock’s Fair Value

The Dividend Discount Model (DDM) takes center stage, offering a method to calculate a company's stock price based on the summation of all future dividend payments. These dividends are then discounted back to their present value at a fair rate, often referred to as the discount rate or cost of equity. Selecting the appropriate discount rate is crucial, as it accounts for the time value of money and the risk associated with the investment. Much like inflation diminishes the value of money over time, the discount rate ensures that future dividends are evaluated accurately in today's terms.

For example, imagine lending a friend $100, and they return the borrowed sum after a year. You might assume you've recovered your money, but in reality, you've lost some of its purchasing power due to inflation. The present value of $110 next year is $100 if the inflation rate is 10%. The Dividend Discount Model employs a similar principle, using the discount rate as a proxy for inflation. Various forms of DDM exist, catering to scenarios where dividends remain constant, grow steadily, or even fluctuate.

Discount Rate Calculation

So, how do we determine the discount rate or cost of equity? The formula involves:

Discount Rate = Risk-Free Rate + Beta * (Market's Annual Return - Risk-Free Rate)

Beta quantifies a stock's volatility and can be found on financial websites. The risk-free rate is typically based on government bond yields, reflecting minimal risk. The market's annual return represents the historical average annualized return of the stock market.

Discounted Cash-flow (DCF) Calculator

The Discounted Cash-flow Model takes a quantitative approach, calculating a company's stock price by summing all future free cash flows and discounting them at a rate that incorporates time and risk. This method acknowledges that money today is worth more than the same amount in the future due to its earning potential.

Peter Lynch’s Fair Value Formula

Famed investor Peter Lynch offers a straightforward approach to fair value using the PEGY ratio, which inverts to determine valuation. The ratio compares a company's growth rate (including dividend yield) to its Price-to-Earnings ratio (P/E). A ratio of 1 suggests fair valuation, while values below 1 indicate overvaluation and above 3 signal significant undervaluation.

Benjamin Graham’s Number Calculator

Benjamin Graham's Number serves as a cap on a stock's price, ensuring you don't overpay. The formula considers the maximum acceptable Price-to-Earnings (P/E) and Price-to-Book (P/B) ratios. These parameters can be customized based on industry averages or a stock's long-term historical data.

In this post, we'll delve deeper into each of these valuation methods, providing examples and insights to equip you for the world of stock valuation. Whether you're a newcomer or a seasoned investor, the journey to understanding and mastering fair value calculations begins here. So, let's embark on this enlightening expedition into the realm of stock analysis.

Unlocking the Power of Fair Value

Now that we've set the stage, let's delve into each valuation method and explore how they can be harnessed to calculate the fair value of any stock:

Multi-Stage DDM Calculator for Stock’s Fair Value

Zero-Growth DDM: Imagine a stock that pays a constant dividend forever. This scenario is covered by the Zero-Growth DDM. The intrinsic value of such a stock can be calculated with a simple formula:

P0 = D / r


  • P0 is the calculated intrinsic value of the stock at present time.
  • D represents the annual dividend payment.
  • r is the discount rate.

Gordon Growth Model (GGM): In situations where a stock pays dividends that grow at a constant rate forever, the Gordon Growth Model comes into play. The formula is as follows:

P0 = D1 / (r - g)


  • P0 signifies the calculated intrinsic value of the stock at present time.
  • D1 represents next year's annual dividend payment.
  • r is the discount rate.
  • g stands for the constant dividend growth rate of the stock.

If you only have information on this year's dividend, you can use the following formula for constant growth DDM:

P0 = (D0 * (1 + g)) / (r - g)


  • P0 is the calculated intrinsic value of the stock at present time.
  • D0 represents this year's annual dividend payment.
  • r is the discount rate.
  • g signifies the constant dividend growth rate of the stock.

Variable Growth Multi-stage DDM: This method is designed for stocks you intend to hold for several years, with dividend payments experiencing variable growth rates during that time.

How to Customize Benjamin Graham’s Number

Graham’s Number is a maximum price that, if exceeded, suggests an overpriced stock. You can customize this formula in two ways:

  • Use Sector/Industry Median: Recognizing that industries have different dynamics, you can customize the parameters based on sector or industry averages. This approach ensures your valuation aligns with industry-specific benchmarks.
  • Use Stock’s Long-term Mean: Everything tends to revert to a mean value over time. By using a stock's long-term mean for P/E and P/B, you can tailor the formula to fit the stock's historical performance.
