What is how to calculate cost of equity using dividend growth model?
Knowing how to calculate cost of equity using dividend growth model (also known as the Gordon Growth Model) is a fundamental skill for financial analysts, corporate treasurers, and retail investors. This method estimates the rate of return that a company must provide to its shareholders in exchange for their investment, specifically focusing on the stream of dividends the company pays.
The core logic behind how to calculate cost of equity using dividend growth model is that the value of a stock is the present value of all future dividends. By rearranging this relationship, we can determine the “discount rate” or cost of equity that the market is currently applying to those cash flows. It is widely used for mature companies with stable, predictable dividend policies.
Common misconceptions include the idea that this model works for all stocks. In reality, how to calculate cost of equity using dividend growth model is only applicable to firms that pay dividends. Growth stocks that reinvest all earnings back into the business cannot be valued directly with this specific formula without making significant assumptions about future dividend initiations.
How to Calculate Cost of Equity Using Dividend Growth Model: Formula and Mathematical Explanation
The mathematical derivation of how to calculate cost of equity using dividend growth model starts with the Dividend Discount Model (DDM). The simplified constant growth version is expressed as:
To use this correctly, follow these steps:
- Identify the current dividend (D₀).
- Forecast the next year’s dividend (D₁) by multiplying D₀ by (1 + g).
- Divide the forecasted dividend by the current market price (P₀) to find the dividend yield.
- Add the constant growth rate (g) to the dividend yield.
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Kₑ | Cost of Equity | Percentage (%) | 7% – 15% |
| D₁ | Dividend Next Period | Currency ($) | Varies by stock |
| P₀ | Current Stock Price | Currency ($) | Market value |
| g | Growth Rate | Percentage (%) | 2% – 6% |
Practical Examples of How to Calculate Cost of Equity Using Dividend Growth Model
Example 1: Utility Company Analysis
Suppose a stable utility company pays an annual dividend of $4.00 per share (D₀). The stock is currently trading at $80.00 (P₀). Analysts expect the company to grow its dividend at a steady 3% per year (g). To learn how to calculate cost of equity using dividend growth model here:
- D₁ = $4.00 * (1 + 0.03) = $4.12
- Dividend Yield = $4.12 / $80.00 = 5.15%
- Cost of Equity = 5.15% + 3.00% = 8.15%
Example 2: Consumer Staple Revaluation
A consumer staple brand is trading at $120.00. It just paid a $2.00 dividend. Investors expect an aggressive 7% growth. Applying how to calculate cost of equity using dividend growth model:
- D₁ = $2.00 * 1.07 = $2.14
- Dividend Yield = $2.14 / $120.00 = 1.78%
- Cost of Equity = 1.78% + 7% = 8.78%

Key Factors That Affect How to Calculate Cost of Equity Using Dividend Growth Model Results
- Interest Rates: Higher market interest rates generally lead to higher required returns for equity (Kₑ).
- Dividend Policy: If a company changes its payout ratio, the “g” and “D” variables will shift, altering the result.
- Market Sentiment: Changes in P₀ (stock price) inversely affect the cost of equity; as price falls, Kₑ rises.
- Inflation: High inflation usually drives up both growth expectations and required rates of return.
- Company Risk Profile: Riskier companies must offer a higher dividend yield to attract investors.
- Sustainable Growth: The growth rate (g) cannot exceed the overall economy’s growth rate indefinitely, or the model fails.
Frequently Asked Questions (FAQ)
Can I use this model for a stock that doesn’t pay dividends?
No, the primary requirement for how to calculate cost of equity using dividend growth model is a consistent dividend stream. For non-dividend stocks, use the CAPM (Capital Asset Pricing Model).
What happens if the growth rate is higher than the cost of equity?
The mathematical model becomes unstable (negative value). In the real world, a company cannot grow faster than its required return forever.
Is the DGM better than CAPM?
Neither is “better.” CAPM focuses on market risk (beta), while DGM focuses on dividends. Analysts often use both to find a range of values when determining how to calculate cost of equity using dividend growth model.
Where do I find the growth rate?
You can use the retention ratio (1 – payout ratio) multiplied by the Return on Equity (ROE), or look at historical dividend growth over 5-10 years.
Does this account for taxes?
The standard DGM calculates the pre-tax cost of equity for the investor, which is the cost for the firm.
Why is the stock price in the denominator?
The price represents the investment amount. Dividends divided by price equals the current yield on that investment.
Is “g” really constant?
In the Gordon Growth Model version of how to calculate cost of equity using dividend growth model, we assume a single constant rate. Multistage models exist for varying growth.
How often should I recalculate the cost of equity?
At least quarterly or whenever there is a significant change in the stock price or dividend announcement.
