The Constant Growth Formula is a powerful tool for calculating stock price, and it's surprisingly simple to use. It's based on the idea that a company's earnings will grow at a constant rate over time.
To use the formula, you'll need to know the company's current stock price and its earnings per share (EPS). This information can usually be found on financial websites or in the company's annual reports.
The formula itself is P = EPS / (r - g), where P is the stock price, EPS is the earnings per share, r is the required rate of return, and g is the growth rate.

What Is the Constant Growth Formula?
The constant growth formula is a key component of the constant growth DDM, which assumes a fixed annual percentage growth rate for dividend payments. This formula is used to value mature companies with steadily increasing dividend payments.
The formula is D0 / (r - g), where D0 is the value of the dividend received this year, r is the required rate of return, and g is the growth rate of the dividend.
This formula can be simplified to the Gordon growth model formula, which is used to determine the value of a company's stock by considering the current worth of its upcoming dividend payouts.

Calculating Stock Price

Calculating Stock Price is a crucial step in investing. The constant growth formula is a powerful tool for doing so.
The Gordon Growth Model is a useful tool for evaluating stocks and pinpointing undervalued ones. It considers the anticipated dividend growth rate and required rate of return to calculate a stock's intrinsic value.
Investors can use this model to identify stocks trading below their fair value, presenting an opportunity for capital appreciation. This is particularly useful for investors looking to grow their wealth over time.
Determining a stock's value using scenarios of constant dividend growth is another approach. This method helps investors understand how different growth rates can impact a stock's price.
By considering different scenarios, investors can gain a deeper understanding of a stock's potential and make more informed investment decisions.

Understanding the Formula
The constant growth formula is a powerful tool for estimating a fair stock price based on its dividend payouts and growth rate. It's a straightforward formula that takes into account the current stock price, current annual dividends, and the required rate of return.

To determine the annual dividends, you'll need to forecast long-term income and compute a percent of that income to be paid out. This can be a bit tricky, but it's a crucial step in calculating the stock price.
The required rate of return is another important factor in the formula. To find it, you'll need to look at the dividend growth rate over a given period. For example, if the starting dividend value in 2019 was $2.00 and the end dividend value in 2020 was $2.05, the dividend growth rate would be 2.5% (calculated as ($2.05 / $2.00) - 1) X 100.
The formula itself is simple: Constant Growth Rate = (Current stock price X r) - Current annual dividends / (Current stock price + Current annual dividends). But what does it all mean?
Here's a breakdown of the key components:
- Current stock price: This is the current market value of the stock.
- r: The required rate of return, which is the expected return on investment.
- Current annual dividends: This is the amount of money paid out to shareholders in the form of dividends.
- Dividend growth rate: This is the rate at which the dividend payments are expected to grow.
By plugging in these values, you can calculate the estimated stock price. For example, if a company has just paid a dividend of INR 3 per share, expects dividends to grow at 5% annually, and the required rate of return is 8%, the stock price would be calculated as follows:
- Calculate the expected dividend for the next period: D1 = D0 x (1 + g) = 3 x (1 + 0.05) = 3.15
- Apply the GGM formula: P0 = D1 / r - g = 3.15 / 0.08 - 0.05 = 3.15 / 0.03 = 105
So, the estimated stock price would be INR 105.
Example and Application

The Gordon Growth Model is a simple yet powerful tool for calculating the net present value of a stock. It uses a straightforward formula to determine the stock's value based on its dividend growth rate and required return.
A key aspect of the model is the calculation of the expected dividend for the next period, which is done by multiplying the current dividend by (1+g), as seen in Example 2. This is a crucial step in determining the stock's value.
The GGM formula itself is P0=D1/r−g, where P0 is the stock price, D1 is the expected dividend for the next period, r is the required rate of return, and g is the dividend growth rate. This formula is applied in Example 2 to calculate the stock price.
To illustrate this, let's consider Example 1, where a company has a dividend of $2.50 per share and a dividend growth rate of 5%. Using the GGM formula, we can calculate the stock's value as $2.50 / (0.11 - 0.05) = $41.67. This means that if the stock trades around this price, it's a fair value for investors.
A stock price well above this level suggests the market has overvalued the stock, while one considerably below it implies an undervalued stock.
