The Gordon Growth Model GGM is a method used to find the fair value of a stock based on future dividends that grows at a constant growth rate. As a form of dividend discount model DDM, the Gordon Growth Model assumes that a company will keep paying dividend payments that rise at a steady growth pace forever. Understanding the Gordon Growth Model formula starts with three inputs: the expected dividend per share for next year, the required rate of return that investors demand, and the expected dividend growth rate. The formula divides next year's dividend per share by the gap between the required rate of return and the constant growth rate to produce a fair stock value.
To see how the model works, consider a stock with a two dollar dividend per share that has a growth rate of dividends at four percent per year. If the required returns for this stock equal ten percent, the Gordon Growth Model values it at about thirty-three dollars. When market prices fall below this figure, the stock looks cheap and may offer a good buying chance. When market prices sit above the calculated value, the stock may be too expensive. This simple comparison between model output and market prices helps investors spot deals in the dividend-paying space.
The cost of equity serves as the discount rate in the Gordon Growth Model and plays a central role in the result. Analysts often derive the cost of equity from the Capital Asset Pricing Model, which adds a risk premium to the risk-free rate based on how much the stock moves with the broader market. Small shifts in growth rates discount rates can change the output by large amounts, so getting both inputs right matters a great deal. The relationship between growth rates discount rates must always show the required returns exceeding the growth rate, or the formula breaks down and gives a negative or infinite result.
Despite its clean design, the limitations of the Gordon Growth model are worth noting. The model only works for firms that pay regular dividend payments and show steady growth patterns. Companies in fast-changing sectors rarely grows at a constant rate, which means the model may not reflect their true worth. High-growth firms that reinvest all profits instead of paying dividends fall outside its scope entirely. For these cases, a discounted cash flow approach using projected future dividends across multiple stages may produce better results than the single-stage Gordon Growth Model.
Value investors still rely on the Gordon Growth Model as a quick screen for dividend stocks trading at fair or below-fair prices. Pairing it with other tools like discounted cash flow models and relative valuation methods gives a fuller picture of what a stock should be worth. The required rate of return and expected dividend growth rate remain the two most important inputs, and even small errors in these figures can lead to large swings in the final value. Careful research into a company s payout history and future earnings potential helps ensure the model gives useful results for long term investment choices.
