What is Market Price Per Share Using Dividend Growth Model?
The concept of “market price per share using dividend growth model,” often referred to as the Gordon Growth Model (GGM) or a form of the Dividend Discount Model (DDM), is a fundamental valuation method used in finance to estimate the intrinsic value of a company’s stock. It posits that the fair value of a stock is the present value of all its future dividends, assuming these dividends grow at a constant rate indefinitely.
This model is particularly useful for valuing mature companies that have a stable history of paying dividends and are expected to continue doing so with a predictable growth rate. It provides a theoretical price that an investor should be willing to pay for a stock, based purely on its dividend-paying capacity and the investor’s required rate of return.
Who Should Use It?
- Value Investors: Those looking for undervalued stocks by comparing the model’s intrinsic value to the current market price.
- Dividend Investors: Individuals focused on income generation from their investments, who want to assess the fairness of a stock’s price relative to its dividend stream.
- Financial Analysts: Professionals who use various valuation models to provide investment recommendations.
- Students and Academics: For understanding core equity valuation principles.
Common Misconceptions
- Applicability to All Stocks: The model is not suitable for companies that do not pay dividends, have erratic dividend policies, or are in early growth stages with unpredictable future earnings.
- Constant Growth Rate: The assumption of a constant, perpetual growth rate is a significant simplification. Real-world growth rates fluctuate.
- Sensitivity to Inputs: Small changes in the required rate of return or growth rate can lead to large swings in the estimated market price per share, making it highly sensitive.
- Growth Rate vs. Required Return: It’s crucial that the growth rate (g) is strictly less than the required rate of return (r). If g ≥ r, the formula yields an infinite or negative value, which is economically meaningless.
Market Price Per Share Using Dividend Growth Model Formula and Mathematical Explanation
The core of calculating market price per share using the dividend growth model lies in a simple yet powerful formula. It’s derived from the present value of a growing perpetuity.
The Formula
The formula for the market price per share (P0) using the Dividend Growth Model is:
P0 = D1 / (r – g)
Variable Explanations
- P0: Market Price Per Share
This is the intrinsic value or fair market price of the stock today, according to the model. - D1: Expected Dividend Per Share Next Year
This is the dividend that the company is expected to pay out per share over the next year. It’s crucial to use D1 (next year’s dividend), not D0 (current year’s dividend). If only D0 is known, D1 can be calculated as D0 * (1 + g). - r: Required Rate of Return
Also known as the discount rate or cost of equity, this is the minimum rate of return an investor expects to earn for taking on the risk of investing in the stock. It’s typically derived from models like the Capital Asset Pricing Model (CAPM) or by considering the risk-free rate plus a risk premium. It must be expressed as a decimal. - g: Constant Dividend Growth Rate
This is the constant rate at which the company’s dividends are expected to grow indefinitely into the future. This growth rate is assumed to be perpetual and stable. It must be expressed as a decimal.
Step-by-Step Derivation
The Dividend Discount Model (DDM) states that the value of a stock is the present value of all its future dividends:
P0 = D1/(1+r)^1 + D2/(1+r)^2 + D3/(1+r)^3 + …
If dividends grow at a constant rate ‘g’, then D2 = D1(1+g), D3 = D1(1+g)^2, and so on. Substituting this into the equation:
P0 = D1/(1+r) + D1(1+g)/(1+r)^2 + D1(1+g)^2/(1+r)^3 + …
This is a geometric series. For an infinite geometric series to converge, the common ratio must be less than 1. In this case, the common ratio is (1+g)/(1+r). For convergence, (1+g)/(1+r) < 1, which implies g < r.
The sum of an infinite geometric series a + ar + ar^2 + … is a / (1 – r_common), where ‘a’ is the first term and ‘r_common’ is the common ratio.
Here, a = D1/(1+r) and r_common = (1+g)/(1+r).
So, P0 = [D1/(1+r)] / [1 – (1+g)/(1+r)]
P0 = [D1/(1+r)] / [(1+r – (1+g))/(1+r)]
P0 = [D1/(1+r)] / [(r – g)/(1+r)]
P0 = D1 / (r – g)
This derivation clearly shows why the condition r > g is critical for the model to produce a finite and meaningful market price per share.
Variables Table
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| P0 | Estimated Market Price Per Share | Currency (e.g., $) | Varies widely |
| D1 | Expected Dividend Per Share Next Year | Currency (e.g., $) | $0.10 – $5.00+ |
| r | Required Rate of Return | % (decimal in formula) | 8% – 15% |
| g | Constant Dividend Growth Rate | % (decimal in formula) | 0% – 7% (must be < r) |
Practical Examples (Real-World Use Cases)
Example 1: Valuing a Stable Utility Company
Imagine you are evaluating a mature utility company, “SteadyPower Inc.”, known for its consistent dividend payments.
- Expected Dividend Next Year (D1): $2.00 per share
- Required Rate of Return (r): 9% (0.09)
- Constant Dividend Growth Rate (g): 4% (0.04)
Using the formula:
P0 = D1 / (r – g)
P0 = $2.00 / (0.09 – 0.04)
P0 = $2.00 / 0.05
P0 = $40.00
Interpretation: Based on these inputs, the intrinsic market price per share for SteadyPower Inc. is estimated to be $40.00. If the stock is currently trading below $40.00, it might be considered undervalued by this model, assuming the inputs are accurate and sustainable.
Example 2: Valuing a Growth-Oriented Dividend Payer
Consider “TechGrow Corp.”, a technology company that pays dividends and is expected to grow them at a slightly higher rate due to its market position.
- Expected Dividend Next Year (D1): $1.20 per share
- Required Rate of Return (r): 12% (0.12)
- Constant Dividend Growth Rate (g): 7% (0.07)
Using the formula:
P0 = D1 / (r – g)
P0 = $1.20 / (0.12 – 0.07)
P0 = $1.20 / 0.05
P0 = $24.00
Interpretation: For TechGrow Corp., the estimated market price per share is $24.00. Despite a lower initial dividend, the higher growth rate and higher required return (reflecting potentially higher risk) lead to this valuation. This highlights how the interplay of ‘r’ and ‘g’ significantly impacts the final price.
How to Use This Market Price Per Share Using Dividend Growth Model Calculator
Our calculator simplifies the process of applying the Dividend Growth Model. Follow these steps to get your estimated market price per share:
Step-by-Step Instructions
- Enter Expected Dividend Per Share Next Year (D1): Input the dividend amount you expect the company to pay per share in the upcoming year. If you only have the current dividend (D0), estimate D1 by multiplying D0 by (1 + your estimated growth rate). For example, if D0 is $1.00 and g is 5%, D1 would be $1.00 * (1 + 0.05) = $1.05.
- Enter Required Rate of Return (r) (%): Input your desired annual rate of return for this investment, as a percentage. This reflects the risk associated with the stock. A higher risk typically warrants a higher required return.
- Enter Constant Dividend Growth Rate (g) (%): Input the expected constant annual growth rate of the company’s dividends, as a percentage. This rate should be sustainable and less than your required rate of return.

- Market Price Chart: The chart visually represents the relationship between the dividend growth rate and the estimated market price, offering a quick insight into the model’s dynamics.
Decision-Making Guidance
If the calculated market price per share (P0) is higher than the current market price of the stock, the stock might be considered undervalued, suggesting a potential buying opportunity. Conversely, if P0 is lower than the current market price, the stock might be overvalued. Remember, this model is just one tool; always combine its insights with other valuation methods and qualitative analysis before making investment decisions.
Key Factors That Affect Market Price Per Share Using Dividend Growth Model Results
The accuracy and reliability of the market price per share calculated by the Dividend Growth Model are highly dependent on the quality of its inputs. Several key factors can significantly influence the results:
- Expected Dividend Next Year (D1): This is the numerator of the formula. A higher expected dividend directly leads to a higher estimated market price per share. Accurately forecasting D1 requires careful analysis of a company’s historical dividend payments, earnings stability, payout ratio, and future growth prospects.
- Required Rate of Return (r): This represents the investor’s hurdle rate and is in the denominator. A higher required rate of return (due to increased perceived risk or higher opportunity costs) will decrease the estimated market price per share. This factor is subjective and varies among investors based on their risk tolerance and alternative investment opportunities.
- Constant Dividend Growth Rate (g): This is also in the denominator and has a profound impact. A higher growth rate leads to a significantly higher estimated market price per share, especially as ‘g’ approaches ‘r’. Estimating ‘g’ involves analyzing historical growth, industry trends, company-specific growth drivers, and management’s future outlook. It’s crucial that ‘g’ is sustainable and less than ‘r’.
- Sustainability of Growth: The model assumes a perpetual, constant growth rate. In reality, companies cannot grow dividends at a high rate indefinitely. Overly optimistic growth rate assumptions can lead to significantly inflated valuations. A sustainable growth rate is often linked to a company’s return on equity and its retention ratio.
- Market Conditions and Economic Outlook: Broader economic factors, such as interest rates, inflation, and overall market sentiment, can influence both the required rate of return (r) and the expected dividend growth rate (g). For instance, rising interest rates might increase ‘r’, thereby lowering valuations.
- Company-Specific Risk: Factors unique to the company, such as competitive landscape, management quality, debt levels, and regulatory environment, all contribute to the perceived risk and thus influence the required rate of return. Higher company-specific risk will demand a higher ‘r’, reducing the calculated market price per share.
- Dividend Payout Policy: A company’s policy on how much of its earnings it pays out as dividends versus reinvesting for growth can impact both D1 and ‘g’. A higher payout ratio might mean a higher D1 but potentially lower future growth, and vice-versa.
Frequently Asked Questions (FAQ)
A: The primary limitation is its assumption of a constant, perpetual dividend growth rate and the requirement that the growth rate must be strictly less than the required rate of return. It’s also not suitable for non-dividend-paying stocks or companies with unpredictable dividend policies.
A: No, the Dividend Growth Model is explicitly based on future dividend payments. For non-dividend-paying companies, other valuation methods like Discounted Cash Flow (DCF) or comparable company analysis are more appropriate.
A: The required rate of return can be estimated using models like the Capital Asset Pricing Model (CAPM), which considers the risk-free rate, the stock’s beta, and the market risk premium. Alternatively, it can be a subjective rate based on an investor’s personal hurdle rate.
A: If ‘g’ is greater than or equal to ‘r’, the formula yields an infinite or negative stock price, which is economically illogical. This indicates that the model is not applicable under such conditions, as it implies unsustainable growth or an unrealistic required return.
A: No, it’s one of several valuation models. Other popular methods include Discounted Cash Flow (DCF), Price-to-Earnings (P/E) ratio, Price-to-Book (P/B) ratio, and Enterprise Value to EBITDA (EV/EBITDA). A comprehensive valuation often involves using multiple models.
A: You should update your inputs whenever there are significant changes in the company’s dividend policy, earnings outlook, industry growth prospects, or changes in market interest rates and your personal required rate of return. Regularly reviewing inputs ensures the valuation remains relevant.
A: D0 is the dividend that has just been paid (the current dividend). D1 is the dividend expected to be paid in the next period (next year’s dividend). The Dividend Growth Model uses D1 because it values future cash flows.
A: Yes, a simplified version of the DDM can be used for preferred stock, as preferred stock typically pays a fixed dividend indefinitely (meaning g=0). In this case, P0 = D1 / r.
