Understanding the Cost of Common Equity using Gordon Growth Model

A) What is Cost of Common Equity using Gordon Growth Model?

The Cost of Common Equity using Gordon Growth Model, also known as the Dividend Discount Model (DDM) with constant growth, is a fundamental concept in finance used to estimate the required rate of return for a company’s common stock. It represents the return that equity investors expect to receive for bearing the risk of holding the company’s shares. This model is particularly useful for valuing dividend-paying stocks that are expected to grow their dividends at a constant rate indefinitely.

Who should use it:

• Investors: To determine if a stock’s current market price offers an adequate return given its dividend stream and growth prospects.
• Financial Analysts: For equity valuation, capital budgeting decisions, and assessing a company’s overall cost of capital.
• Companies: To understand the cost of raising equity capital and to set appropriate hurdle rates for investment projects.

Common misconceptions:

• Applicability: It’s often mistakenly applied to non-dividend-paying stocks or companies with erratic dividend growth. The model strictly assumes a constant, perpetual dividend growth rate.
• Growth Rate: The “constant growth rate” (g) must be less than the Cost of Common Equity (Ke). If g ≥ Ke, the model yields an infinite or negative stock price, which is illogical.
• Sensitivity: Users sometimes underestimate the model’s sensitivity to changes in the growth rate. Even small adjustments to ‘g’ can significantly alter the calculated Cost of Common Equity using Gordon Growth Model.

B) Cost of Common Equity using Gordon Growth Model Formula and Mathematical Explanation

The Gordon Growth Model is a variation of the Dividend Discount Model (DDM) that assumes dividends grow at a constant rate. The formula for the Cost of Common Equity using Gordon Growth Model (Ke) is:

Ke = (D1 / P0) + g

Where:

• D1 = Expected Dividend per share next year
• P0 = Current Market Price per share
• g = Constant Growth Rate of Dividends (expressed as a decimal)

To calculate D1, we use the current dividend (D0) and the growth rate (g):

D1 = D0 * (1 + g)

Step-by-step derivation:

1. The basic Dividend Discount Model states that the intrinsic value of a stock (P0) is the present value of all future dividends.
2. If dividends grow at a constant rate (g), the future dividends are D1, D1(1+g), D1(1+g)^2, and so on.
3. The formula for the present value of a growing perpetuity is P0 = D1 / (Ke – g).
4. Rearranging this formula to solve for Ke gives us: Ke = (D1 / P0) + g. This is the Cost of Common Equity using Gordon Growth Model.

Variables for the Gordon Growth Model

Variable	Meaning	Unit	Typical Range
D0	Current Dividend per Share	Currency ($)	$0.01 – $10.00+
P0	Current Market Price per Share	Currency ($)	$1.00 – $1000.00+
g	Expected Dividend Growth Rate	Decimal (%)	0% – 10% (must be < Ke)
D1	Expected Dividend Next Year	Currency ($)	Calculated
Ke	Cost of Common Equity	Decimal (%)	5% – 20%

C) Practical Examples (Real-World Use Cases)

Let’s illustrate how to calculate the Cost of Common Equity using Gordon Growth Model with practical examples.

Example 1: Stable Growth Company

Imagine Company X, a mature utility company, has just paid a dividend (D0) of $1.50 per share. Its stock is currently trading at $30.00 per share (P0), and analysts expect its dividends to grow at a constant rate (g) of 4% annually.

• Current Dividend (D0): $1.50
• Current Market Price (P0): $30.00
• Expected Dividend Growth Rate (g): 4% (or 0.04 as a decimal)

Calculation:

1. Calculate Expected Dividend Next Year (D1):
   D1 = D0 * (1 + g) = $1.50 * (1 + 0.04) = $1.50 * 1.04 = $1.56
2. Calculate Dividend Yield (D1 / P0):
   Dividend Yield = $1.56 / $30.00 = 0.052 (or 5.2%)
3. Calculate Cost of Common Equity (Ke):
   Ke = (D1 / P0) + g = 0.052 + 0.04 = 0.092 (or 9.2%)

For Company X, the Cost of Common Equity using Gordon Growth Model is 9.2%. This means investors require a 9.2% return to hold Company X’s stock, given its dividend policy and growth expectations.

Example 2: Growth-Oriented Company

Consider Company Y, a growing tech firm, which paid a dividend (D0) of $0.80 per share. Its stock trades at $50.00 per share (P0), and its dividends are projected to grow at 7% annually.

• Current Dividend (D0): $0.80
• Current Market Price (P0): $50.00
• Expected Dividend Growth Rate (g): 7% (or 0.07 as a decimal)

Calculation:

1. Calculate Expected Dividend Next Year (D1):
   D1 = D0 * (1 + g) = $0.80 * (1 + 0.07) = $0.80 * 1.07 = $0.856
2. Calculate Dividend Yield (D1 / P0):
   Dividend Yield = $0.856 / $50.00 = 0.01712 (or 1.712%)
3. Calculate Cost of Common Equity (Ke):
   Ke = (D1 / P0) + g = 0.01712 + 0.07 = 0.08712 (or 8.712%)

Company Y’s Cost of Common Equity using Gordon Growth Model is approximately 8.71%. Despite a lower dividend yield, its higher growth rate contributes significantly to the overall required return.

D) How to Use This Cost of Common Equity using Gordon Growth Model Calculator

Our calculator simplifies the process of determining the Cost of Common Equity using Gordon Growth Model. Follow these steps to get your results:

1. Input Current Dividend per Share (D0): Enter the most recent annual dividend paid by the company. For example, if a company paid $1.00 per share last year, enter “1.00”.
2. Input Current Market Price per Share (P0): Enter the current trading price of one share of the company’s stock. For instance, if the stock trades at $20.00, enter “20.00”.
3. Input Expected Dividend Growth Rate (g): Enter the anticipated constant annual growth rate of the company’s dividends as a percentage. If dividends are expected to grow by 5%, enter “5”.
4. View Results: The calculator will automatically update the results in real-time as you type.

How to read the results:

• Cost of Common Equity (Ke): This is the primary result, displayed prominently. It represents the minimum rate of return an investor expects to earn from holding the company’s stock.
• Expected Dividend Next Year (D1): This shows the projected dividend payment for the upcoming year, calculated as D0 * (1 + g).
• Dividend Yield (D1/P0): This is the expected dividend next year divided by the current market price, indicating the immediate return from dividends.
• Growth Rate (g): This displays the growth rate you entered, converted to a decimal for clarity in the formula.

Decision-making guidance: The calculated Cost of Common Equity using Gordon Growth Model can be used as a discount rate for future cash flows in valuation models, or as a hurdle rate for new investment projects. A lower Ke might suggest a less risky investment or one with lower growth expectations, while a higher Ke implies higher perceived risk or greater growth potential. Compare this Ke to other investment opportunities or the company’s Weighted Average Cost of Capital (WACC) for a comprehensive financial analysis.

E) Key Factors That Affect Cost of Common Equity using Gordon Growth Model Results

Several critical factors influence the outcome when calculating the Cost of Common Equity using Gordon Growth Model. Understanding these can help in interpreting the results and making informed financial decisions.

• Current Dividend per Share (D0): A higher current dividend, all else being equal, will lead to a higher expected dividend (D1) and thus a higher dividend yield, increasing the calculated Cost of Common Equity. This reflects that investors demand a higher return for a larger immediate payout.
• Current Market Price per Share (P0): The market price is inversely related to the dividend yield. A higher market price (P0) for the same expected dividend (D1) will result in a lower dividend yield, thereby reducing the calculated Cost of Common Equity. This suggests that the market values the company more highly, requiring a lower return.
• Expected Dividend Growth Rate (g): This is arguably the most sensitive input. A higher expected dividend growth rate directly increases the Cost of Common Equity using Gordon Growth Model. Investors expect a higher return from companies that can sustain higher growth in their dividend payments. However, ‘g’ must be less than ‘Ke’ for the model to be valid.
• Market Risk and Investor Sentiment: Broader market conditions, economic outlook, and investor risk appetite can influence the required rate of return. During periods of high market uncertainty, investors typically demand a higher risk premium, which translates to a higher Cost of Common Equity.
• Interest Rates: Benchmark interest rates (like government bond yields) serve as a baseline for risk-free returns. As these rates rise, investors generally demand higher returns from equity investments, pushing up the Cost of Common Equity. Conversely, falling interest rates can lower the required equity return.
• Company-Specific Risk: Factors unique to the company, such as its industry, competitive landscape, financial leverage, and management quality, contribute to its specific risk profile. Higher company-specific risk will lead investors to demand a higher return, increasing the Cost of Common Equity. This is often captured by a company’s beta in other models like the Capital Asset Pricing Model (CAPM).
• Inflation Expectations: Future inflation erodes the purchasing power of future dividends. Investors will demand a higher nominal return to compensate for expected inflation, thereby increasing the Cost of Common Equity.

F) Frequently Asked Questions (FAQ)

Q: When is the Cost of Common Equity using Gordon Growth Model most appropriate?

A: The Gordon Growth Model is best suited for mature, stable companies that pay dividends and are expected to grow those dividends at a constant, predictable rate indefinitely. It’s less appropriate for growth companies that don’t pay dividends or have highly variable dividend policies.

Q: What are the limitations of the Gordon Growth Model?

A: Its main limitations include the assumption of a constant dividend growth rate, which is rarely perfectly true in reality. It also assumes the growth rate (g) is strictly less than the required rate of return (Ke). If g is greater than or equal to Ke, the model breaks down, yielding an infinite or negative stock price. It’s also highly sensitive to the inputs, especially the growth rate.

Q: How does the Gordon Growth Model compare to the Capital Asset Pricing Model (CAPM) for calculating Cost of Common Equity?

A: Both are methods to estimate the Cost of Common Equity. The Gordon Growth Model focuses on dividends and their growth, while CAPM focuses on systematic risk (beta), the risk-free rate, and the market risk premium. They can be used as complementary tools, with CAPM often preferred for non-dividend-paying stocks or when a reliable growth rate is hard to estimate. Our Capital Asset Pricing Model (CAPM) calculator can help you explore this further.

Q: Can I use this model for non-dividend paying stocks?

A: No, the Gordon Growth Model explicitly relies on current and future dividend payments. It cannot be used for companies that do not pay dividends. For such companies, other valuation models like the Free Cash Flow to Equity (FCFE) model or CAPM are more appropriate.

Q: What if the expected dividend growth rate (g) is higher than the calculated Cost of Common Equity (Ke)?

A: If g ≥ Ke, the Gordon Growth Model becomes invalid. Mathematically, it would imply an infinite or negative stock price, which is not realistic. This scenario suggests that the assumptions of the model (perpetual constant growth rate less than the discount rate) are not met, or the growth rate is unsustainable in the long run.

Q: How sensitive is the model to the growth rate?

A: The model is highly sensitive to the growth rate (g). A small change in ‘g’ can lead to a significant change in the calculated Cost of Common Equity. This sensitivity underscores the importance of accurately estimating the long-term sustainable growth rate.

Q: What is a “good” Cost of Common Equity?

A: There isn’t a universally “good” Cost of Common Equity; it’s relative. It depends on the company’s risk profile, industry, and prevailing market conditions. A lower Ke generally indicates lower perceived risk or lower growth expectations, while a higher Ke suggests higher risk or higher growth potential. It should be compared to the company’s Weighted Average Cost of Capital (WACC) and the returns of similar investments.

Q: How often should I recalculate the Cost of Common Equity?

A: It’s advisable to recalculate the Cost of Common Equity whenever there are significant changes in the company’s dividend policy, market price, growth prospects, or broader market conditions (e.g., interest rates, market risk premium). For ongoing analysis, quarterly or semi-annual reviews are common.
