Gordon Growth Model Calculator
Calculate the Cost of Equity using the Gordon Growth Model (a variant of the Dividend Discount Model). This tool helps investors and analysts estimate the required rate of return on an investment in a company’s stock, assuming dividends grow at a constant rate indefinitely.
Gordon Growth Model Inputs
The most recently paid dividend per share.
The constant annual growth rate of dividends (in percentage). Must be less than the required rate of return.
The current market price of one share of stock.

What is the Cost of Equity using the Gordon Growth Model?
The Cost of Equity, often calculated using the Gordon Growth Model (also known as the Dividend Discount Model or DDM), represents the return a company requires to justify investing in its stock. In simpler terms, it’s the rate of return that equity investors demand for providing capital to a company. This cost is critical for companies making investment decisions, as projects undertaken should ideally yield returns higher than this cost of equity to create shareholder value. The Gordon Growth Model specifically focuses on dividend-paying stocks, assuming that dividends will grow at a constant rate indefinitely.
Who should use it: This model is most applicable to mature, stable companies that have a consistent history of paying dividends and are expected to continue doing so with predictable growth. It’s a valuable tool for:
- Financial analysts and portfolio managers
- Investors evaluating dividend-paying stocks
- Companies determining their weighted average cost of capital (WACC)
- Academics studying corporate finance and valuation
Common misconceptions: A frequent misunderstanding is that the Gordon Growth Model is a universal tool for all stocks. It’s not suitable for companies that do not pay dividends, companies with erratic dividend payouts, or high-growth startups where dividend growth is highly unpredictable. Another misconception is that the ‘constant growth rate’ is set in stone; in reality, it’s an assumption that requires careful forecasting. The model also implicitly assumes that the required rate of return (cost of equity) is greater than the dividend growth rate (g < Ke), a condition that is generally met in practice.
Cost of Equity Formula and Mathematical Explanation
The Gordon Growth Model is derived from the general Dividend Discount Model, which states that the present value of a stock is the sum of all expected future dividends, discounted back to the present at the required rate of return (cost of equity). For a constant growth scenario, this simplifies into a manageable formula.
The standard formula for the present value of a stock (P0) with dividends growing at a constant rate (g) is:
P0 = D1 / (Ke – g)
Where:
- P0 = Current market price of the stock
- D1 = Expected dividend per share next year
- Ke = Cost of Equity (required rate of return)
- g = Constant dividend growth rate
To find the Cost of Equity (Ke), we can rearrange this formula:
Ke – g = D1 / P0
Ke = (D1 / P0) + g
Furthermore, the expected dividend next year (D1) is calculated based on the current dividend (D0) and the growth rate (g):
D1 = D0 * (1 + g)
Substituting this into the Ke formula gives us the version used in our calculator:
Ke = [D0 * (1 + g) / P0] + g
Variable Explanations:
| Variable | Meaning | Unit | Typical Range / Notes |
|---|---|---|---|
| Ke | Cost of Equity | Percentage (%) | Typically 8% – 15% or higher, depends on risk. Must be > g. |
| D1 | Expected Dividend Per Share Next Year | Currency (e.g., $) | Calculated from D0 and g. |
| D0 | Current Dividend Per Share | Currency (e.g., $) | Most recently paid dividend. e.g., $1.00 – $10.00+ |
| P0 | Current Stock Price | Currency (e.g., $) | Current market price per share. e.g., $20.00 – $200.00+ |
| g | Constant Dividend Growth Rate | Percentage (%) | Assumed constant forever. Typically 2% – 6%. Must be < Ke. |
Practical Examples (Real-World Use Cases)
The Gordon Growth Model provides valuable insights when applied to real companies. Here are two examples:
Example 1: Established Utility Company
A stable utility company, “PowerGrid Inc.”, recently paid a dividend of $3.00 per share (D0). Analysts expect its dividends to grow consistently at 4% per year (g) for the foreseeable future. The current market price of PowerGrid Inc. stock is $60.00 per share (P0).
Inputs:
- D0 = $3.00
- g = 4.0%
- P0 = $60.00
Calculation:
- D1 = $3.00 * (1 + 0.04) = $3.12
- Ke = ($3.12 / $60.00) + 0.04
- Ke = 0.052 + 0.04
- Ke = 0.092 or 9.2%
Interpretation: The cost of equity for PowerGrid Inc. is estimated to be 9.2%. This means investors require an average annual return of 9.2% from their investment in PowerGrid stock, considering both dividends and growth. If PowerGrid’s required return by investors were lower than 9.2%, its stock price might be higher, or its dividends might be expected to grow faster.
Example 2: Mature Consumer Goods Company
Consider “GlobalFoods Corp.”, a well-established company in the consumer staples sector. It paid a dividend of $1.50 last year (D0) and forecasts a steady dividend growth rate of 3% annually (g). The stock is currently trading at $45.00 per share (P0).
Inputs:
- D0 = $1.50
- g = 3.0%
- P0 = $45.00
Calculation:
- D1 = $1.50 * (1 + 0.03) = $1.545
- Ke = ($1.545 / $45.00) + 0.03
- Ke = 0.03433 + 0.03
- Ke = 0.06433 or approximately 6.43%
Interpretation: The calculated cost of equity for GlobalFoods Corp. is approximately 6.43%. This relatively low cost of equity reflects the company’s stability and low-risk profile, typical for mature businesses in defensive sectors. Investors in GlobalFoods expect a modest return, primarily driven by the consistent dividend growth.
It’s important to remember that the Gordon Growth Model provides an estimate, and its accuracy relies heavily on the validity of its assumptions, particularly the constant growth rate ‘g’.
How to Use This Cost of Equity Calculator
Our Gordon Growth Model calculator is designed for simplicity and speed. Follow these steps to get your cost of equity estimate:
- Enter Current Dividend Per Share (D0): Input the total amount of dividends the company paid out over the last full year, divided by the number of outstanding shares. For example, if a company paid $10 million in dividends and has 5 million shares, D0 is $2.00.
- Enter Expected Dividend Growth Rate (g): Provide the anticipated constant annual percentage rate at which dividends are expected to grow indefinitely. This is often based on historical trends, industry forecasts, and the company’s payout ratio sustainability. Enter this as a percentage (e.g., 5 for 5%).
- Enter Current Stock Price (P0): Input the current trading price of a single share of the company’s stock on the open market.
- Click ‘Calculate Cost of Equity’: The calculator will process your inputs using the Gordon Growth Model formula.
How to read results:
- Main Result (Cost of Equity): This is the primary output, displayed prominently. It represents the annual percentage return investors expect from the stock.
- Intermediate Values: You’ll see the calculated Expected Next Dividend (D1), the input Current Dividend (D0), and the input Growth Rate (g). These help illustrate the components of the calculation.
- Formula Explanation: A brief description of the model and formula used is provided for clarity.
Decision-making guidance: The cost of equity is a crucial benchmark. A company should only invest in projects that are expected to generate returns exceeding this cost. For investors, if the expected return from a stock (based on your analysis or other models) is significantly higher than the calculated cost of equity, it might indicate an undervalued stock. Conversely, if the expected return is lower, the stock might be overvalued or too risky for the required return.

Key Factors That Affect Cost of Equity Results
Several factors influence the calculated cost of equity using the Gordon Growth Model, and their impact can be significant. Understanding these elements is key to interpreting the results accurately:
- Dividend Growth Rate (g): This is perhaps the most sensitive input. A higher expected growth rate directly increases the cost of equity. However, the model requires g < Ke. If 'g' is too high, it might suggest the company's growth is unsustainable, or the model is inappropriate. Conversely, a low or negative 'g' lowers Ke. The Dividend Growth Rate Calculator can help explore various scenarios.
- Current Stock Price (P0): The stock price is in the denominator of the dividend yield component (D1/P0). A higher stock price leads to a lower dividend yield and thus a lower cost of equity, assuming other factors remain constant. Conversely, a falling stock price (with constant dividends and growth) increases the perceived cost of equity.
- Current Dividend (D0): A higher current dividend directly increases the expected next dividend (D1), which in turn increases the dividend yield component (D1/P0) and thus the cost of equity. Companies with generous dividend policies will typically show a higher dividend yield component.
- Market Risk Premium: While not an explicit input in the basic Gordon Growth Model, the stock price (P0) and the expected growth rate (g) are influenced by the overall market sentiment and the perceived risk of the company relative to the market. A higher market risk premium generally leads to higher stock prices (reducing Ke) or higher required returns (increasing Ke), depending on how it’s reflected.
- Company-Specific Risk: The Gordon Growth Model assumes ‘g’ is constant, which implicitly bakes in company-specific risk. However, if a company’s risk profile changes dramatically (e.g., due to new competition, regulatory changes, or strategic shifts), the expected growth rate ‘g’ and the stock price ‘P0’ would likely adjust, impacting Ke.
- Inflation Expectations: Inflation affects both the company’s ability to grow earnings and dividends and the required rate of return by investors. Higher inflation generally leads to higher nominal interest rates, which can increase the cost of equity (Ke). Investors demand a higher nominal return to maintain their real purchasing power.
- Interest Rate Environment: As a component of the required rate of return, interest rates (like the risk-free rate) play a background role. Higher prevailing interest rates tend to push up the cost of equity for all companies, as investors have higher alternative return opportunities.
