What is Cost of Equity using Dividend Growth Model?
The Cost of Equity using Dividend Growth Model, often referred to as the Gordon Growth Model (GGM), is a fundamental valuation method used to estimate the required rate of return on a company’s equity. It posits that the intrinsic value of a stock is the present value of all its future dividends, growing at a constant rate. Consequently, the model can be rearranged to solve for the discount rate that equates the present value of these growing dividends to the current stock price, which is the Cost of Equity.
This model is particularly useful for mature companies with a stable dividend payment history and a predictable growth trajectory. It provides a straightforward way to understand the return investors expect for holding a company’s stock, considering both the dividend income and the capital appreciation implied by dividend growth.
Who should use the Cost of Equity using Dividend Growth Model?
- Equity Investors: To determine if a stock’s current price offers an adequate return given its dividend policy and growth prospects.
- Financial Analysts: As a component in valuation models (e.g., Discounted Cash Flow) or when calculating a company’s Weighted Average Cost of Capital (WACC).
- Corporate Finance Professionals: To understand investor expectations and evaluate the cost of raising equity capital.
- Academics and Students: For learning and applying fundamental valuation principles.
Common Misconceptions about the Dividend Growth Model
- Applicable to all companies: The model assumes a constant dividend growth rate indefinitely, which is unrealistic for many companies, especially those in early growth stages or those that don’t pay dividends.
- Growth rate must be less than Cost of Equity: A critical assumption is that the dividend growth rate (g) must be strictly less than the Cost of Equity (Ke). If g ≥ Ke, the formula yields a negative or undefined result, indicating the model’s limitations.
- Dividends are the only source of return: While the model focuses on dividends, total shareholder return also includes potential capital gains from stock price appreciation, which is implicitly linked to dividend growth but not explicitly separated.
- Ignores risk: While the Cost of Equity inherently incorporates risk (higher risk, higher required return), the model itself doesn’t directly quantify specific risk factors beyond what’s embedded in the market price and growth expectations.
Cost of Equity using Dividend Growth Model Formula and Mathematical Explanation
The core of the Cost of Equity using Dividend Growth Model lies in its elegant formula, which is derived from the present value of a perpetuity with growth. The model assumes that dividends will grow at a constant rate indefinitely.
Step-by-step Derivation
The intrinsic value of a stock (P0) is the sum of the present value of all future dividends:
P0 = D1/(1+Ke)^1 + D2/(1+Ke)^2 + D3/(1+Ke)^3 + …
Where D1 = D0 * (1+g), D2 = D1 * (1+g) = D0 * (1+g)^2, and so on.
Substituting these into the equation:
P0 = [D0 * (1+g)]/(1+Ke)^1 + [D0 * (1+g)^2]/(1+Ke)^2 + [D0 * (1+g)^3]/(1+Ke)^3 + …
This is a geometric series. For the sum of an infinite geometric series to converge, the common ratio must be less than 1. In this case, (1+g)/(1+Ke) must be less than 1, which implies Ke > g.
If Ke > g, the sum of this infinite series simplifies to:
P0 = D1 / (Ke – g)
To find the Cost of Equity (Ke), we rearrange the formula:
Ke – g = D1 / P0
Ke = (D1 / P0) + g
This formula shows that the Cost of Equity is composed of two parts: the expected dividend yield for the next period (D1/P0) and the constant growth rate of dividends (g).
Variable Explanations
Understanding each variable is crucial for accurate application of the Cost of Equity using Dividend Growth Model.
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Ke | Cost of Equity (Required Rate of Return) | % | 6% – 15% |
| D0 | Current Annual Dividend Per Share | Currency ($) | $0.10 – $10.00+ |
| D1 | Expected Dividend Per Share Next Year (D0 * (1+g)) | Currency ($) | Calculated value |
| P0 | Current Market Price Per Share | Currency ($) | $10.00 – $1000.00+ |
| g | Expected Constant Dividend Growth Rate | % | 1% – 8% |
Practical Examples (Real-World Use Cases)
Let’s illustrate how to calculate the Cost of Equity using Dividend Growth Model with a couple of realistic scenarios.
Example 1: Stable, Mature Company
Consider “Global Innovations Inc.,” a well-established technology company known for its consistent dividend payments.
- Current Annual Dividend Per Share (D0): $3.00
- Current Market Price Per Share (P0): $75.00
- Expected Constant Dividend Growth Rate (g): 4% (0.04)
Step 1: Calculate Expected Next Year’s Dividend (D1)
D1 = D0 * (1 + g) = $3.00 * (1 + 0.04) = $3.00 * 1.04 = $3.12
Step 2: Calculate Cost of Equity (Ke)
Ke = (D1 / P0) + g = ($3.12 / $75.00) + 0.04
Ke = 0.0416 + 0.04 = 0.0816
Result: The Cost of Equity (Ke) for Global Innovations Inc. is 8.16%.
Financial Interpretation: This means investors require an 8.16% annual return to compensate them for the risk of holding Global Innovations Inc.’s stock, given its current price, dividend, and expected growth.
Example 2: Utility Company with Lower Growth
Consider “Reliable Power Co.,” a utility company known for its high dividend yield and very stable, but lower, growth.
- Current Annual Dividend Per Share (D0): $4.50
- Current Market Price Per Share (P0): $60.00
- Expected Constant Dividend Growth Rate (g): 2% (0.02)
Step 1: Calculate Expected Next Year’s Dividend (D1)
D1 = D0 * (1 + g) = $4.50 * (1 + 0.02) = $4.50 * 1.02 = $4.59
Step 2: Calculate Cost of Equity (Ke)
Ke = (D1 / P0) + g = ($4.59 / $60.00) + 0.02
Ke = 0.0765 + 0.02 = 0.0965
Result: The Cost of Equity (Ke) for Reliable Power Co. is 9.65%.
Financial Interpretation: Despite a lower growth rate, the higher dividend yield contributes significantly to the required return. Investors demand a 9.65% return for this utility stock, reflecting its specific risk profile and dividend policy.

How to Read Results
The “Cost of Equity (Ke)” represents the minimum annual rate of return an investor expects to receive for holding the company’s stock. It’s a crucial input for various financial analyses, including discounted cash flow (DCF) models and calculating the Weighted Average Cost of Capital (WACC).
The “Expected Next Year’s Dividend (D1)” is the dividend per share projected for the upcoming year, based on your input for D0 and g.
The “Dividend Yield Component” (D1/P0) shows the portion of the Cost of Equity derived from the expected dividend income relative to the current stock price.
The “Growth Rate Component” (g) shows the portion of the Cost of Equity derived from the expected growth in dividends, which implicitly reflects capital appreciation.
A warning will appear if the growth rate (g) is greater than or equal to the calculated Cost of Equity (Ke), indicating that the model’s underlying assumptions may not hold true for your inputs.
Decision-Making Guidance
The calculated Cost of Equity using Dividend Growth Model can inform several investment and financial decisions:
- Investment Screening: Compare the calculated Ke with your personal required rate of return. If Ke is too low, the stock might not meet your investment criteria.
- Valuation: Use Ke as a discount rate in other valuation models. A higher Ke implies a lower present value for future cash flows.
- Capital Budgeting: Companies use Ke as part of their WACC to evaluate potential projects. Projects must generate returns higher than the cost of capital to be viable.
- Performance Evaluation: Compare a company’s actual returns against its Cost of Equity to assess if it’s meeting investor expectations.
Key Factors That Affect Cost of Equity using Dividend Growth Model Results
The accuracy and applicability of the Cost of Equity using Dividend Growth Model are highly dependent on the quality of its inputs and the underlying assumptions. Several factors can significantly influence the calculated Cost of Equity:
- Current Annual Dividend Per Share (D0): This is a direct input. A higher current dividend, all else being equal, will lead to a higher expected next year’s dividend (D1) and thus a higher dividend yield component, increasing the Cost of Equity. Companies with stable and growing dividends are ideal for this model.
- Current Market Price Per Share (P0): The market price reflects investor sentiment and perceived risk. A lower stock price, while keeping D1 constant, will result in a higher dividend yield component (D1/P0), thereby increasing the calculated Cost of Equity. Conversely, a higher stock price lowers the Cost of Equity.
- Expected Constant Dividend Growth Rate (g): This is perhaps the most critical and subjective input. A higher expected growth rate directly translates to a higher Cost of Equity. Estimating a truly constant growth rate indefinitely is challenging and often requires careful analysis of historical growth, industry trends, and management guidance.
- Market Interest Rates: While not a direct input into the formula, prevailing market interest rates (e.g., risk-free rate) influence investor expectations for returns. Higher risk-free rates might lead investors to demand higher returns from equity, potentially impacting the stock price (P0) and the perceived growth rate (g), thus indirectly affecting the Cost of Equity.
- Company-Specific Risk: The inherent risk of a company (e.g., business risk, financial risk) is implicitly captured in its stock price (P0) and the expected growth rate (g). Companies with higher perceived risk will typically have lower stock prices and/or lower growth expectations, leading to a higher Cost of Equity to compensate investors for that risk.
- Industry Outlook and Economic Conditions: The broader industry and economic environment can impact a company’s ability to grow dividends and its stock price. A booming economy might support higher growth rates and stock prices, potentially lowering the Cost of Equity, while a recession could have the opposite effect.
- Dividend Policy Stability: The model assumes a stable and predictable dividend policy. Companies with erratic dividend payments or those that frequently cut dividends are not good candidates for the Dividend Growth Model, as the “constant growth” assumption breaks down.
- Inflation Expectations: Higher inflation expectations can lead investors to demand higher nominal returns to maintain their real purchasing power. This can push up the required Cost of Equity, as investors factor in the erosion of value due to inflation.
Frequently Asked Questions (FAQ) about Cost of Equity using Dividend Growth Model
Q1: What is the primary assumption of the Dividend Growth Model?
A1: The primary assumption is that dividends will grow at a constant rate indefinitely. It also assumes that the dividend growth rate (g) is less than the Cost of Equity (Ke).
Q2: Can I use the Cost of Equity using Dividend Growth Model for companies that don’t pay dividends?
A2: No, the model is explicitly based on dividends. It cannot be used for companies that do not pay dividends. For such companies, other valuation models like the Capital Asset Pricing Model (CAPM) or Discounted Cash Flow (DCF) are more appropriate.
Q3: How do I estimate the dividend growth rate (g)?
A3: Estimating ‘g’ is crucial. Common methods include using the company’s historical dividend growth rate, analyst forecasts, or the sustainable growth rate (Retention Ratio * Return on Equity). It’s important to use a rate that is sustainable and realistic for the long term.
Q4: What if the growth rate (g) is greater than or equal to the Cost of Equity (Ke)?
A4: If g ≥ Ke, the Dividend Growth Model formula yields a mathematically nonsensical result (negative or infinite value). This indicates that the model is not applicable under these conditions, as its underlying assumption of a converging infinite series is violated. It often suggests that the stock is overvalued or the growth rate is unsustainable in the long run.
Q5: Is the Cost of Equity using Dividend Growth Model suitable for high-growth companies?
A5: Generally, no. High-growth companies often have erratic dividend policies, reinvest most of their earnings, or experience growth rates that are unsustainable in the long term. Multi-stage dividend discount models or other valuation methods are usually better for such companies.
Q6: How does the Cost of Equity using Dividend Growth Model relate to the Weighted Average Cost of Capital (WACC)?
A6: The Cost of Equity (Ke) is a key component of the WACC. WACC is the average rate of return a company expects to pay to all its different security holders (debt and equity). Ke represents the cost of the equity portion of that capital structure.
Q7: What are the limitations of this model?
A7: Key limitations include the assumption of constant dividend growth, the requirement for Ke > g, its inapplicability to non-dividend-paying firms, and its sensitivity to input changes, especially the growth rate.
Q8: Can I use this model for preferred stock?
A8: For preferred stock that pays a fixed dividend and has no growth, a simpler perpetuity formula (Dividend / Required Rate of Return) is used. The Dividend Growth Model is specifically for common stock with growing dividends.
