Cost of Equity Calculator

The Cost of Equity Calculator helps businesses and investors determine the rate of return required by shareholders for investing in a company. This metric is essential in assessing the profitability of equity financing and comparing it to other funding options. By using key models like the Capital Asset Pricing Model (CAPM), Dividend Discount Model (DDM), and Bond Yield Plus Risk Premium Approach, the calculator provides a precise estimate of the cost of equity. This tool is invaluable for financial analysts, corporate managers, and investors who want to make informed decisions regarding investments, capital structure, and shareholder expectations.

Formula of Cost of Equity Calculator

The cost of equity can be calculated using one of the following methods:

1. Capital Asset Pricing Model (CAPM)

Cost of Equity (CAPM):
Cost of Equity = Risk-Free Rate + Beta × (Market Return − Risk-Free Rate)

Formula Components:

• Risk-Free Rate: The return on a risk-free investment, such as government bonds.
• Beta: The stock’s volatility compared to the market.
• Market Return: The expected return on the market portfolio.
• Market Risk Premium: The difference between the Market Return and Risk-Free Rate.

Market Risk Premium Formula:
Market Risk Premium = Market Return − Risk-Free Rate

2. Dividend Discount Model (DDM)

Cost of Equity (DDM):
Cost of Equity = (Next Year’s Dividend / Current Stock Price) + Dividend Growth Rate

Formula Components:

• Next Year’s Dividend: The dividend expected in the next year, calculated as:
  Next Year’s Dividend = Current Dividend × (1 + Dividend Growth Rate)
• Current Stock Price: The current market price of the stock.
• Dividend Growth Rate: The expected annual growth rate of dividends.

3. Bond Yield Plus Risk Premium Approach

Cost of Equity (Bond Yield Method):
Cost of Equity = Yield on Company Bonds + Risk Premium

Formula Components:

• Yield on Company Bonds: The annual return on bonds issued by the company.
• Risk Premium: The additional return expected for equity investments over bonds.

Additional Variables and Their Formulas

Variable	Formula
Market Return	(Ending Market Value − Beginning Market Value + Dividends) / Beginning Market Value
Dividend Growth Rate	(Recent Dividend − Previous Dividend) / Previous Dividend × 100
Beta	Covariance of Stock and Market Returns / Variance of Market Returns

General Terms Table

Below is a table with typical values and their ranges to help users estimate variables used in cost of equity calculations:

Variable	Typical Value Range	Notes
Risk-Free Rate (%)	2–5	Based on long-term government bonds
Beta	0.5–2	Higher values indicate higher risk
Market Return (%)	8–12	Based on historical market performance
Dividend Growth Rate (%)	3–8	Varies by company growth potential
Yield on Company Bonds (%)	3–7	Depends on the company’s credit rating

Example of Cost of Equity Calculator

Scenario:

A company’s financial data includes:

• Risk-Free Rate: 3%
• Beta: 1.2
• Market Return: 10%
• Current Dividend: $2
• Dividend Growth Rate: 5%
• Current Stock Price: $40
• Yield on Company Bonds: 4%
• Risk Premium (Bond Yield Method): 6%

Method 1: Using CAPM

Cost of Equity = Risk-Free Rate + Beta × (Market Return − Risk-Free Rate)
Cost of Equity = 3% + 1.2 × 7% = 3% + 8.4% = 11.4%

Method 2: Using DDM

Cost of Equity = (Next Year’s Dividend / Current Stock Price) + Dividend Growth Rate
Next Year’s Dividend = $2 × (1 + 0.05) = $2.10
Cost of Equity = ($2.10 / $40) + 5%
Cost of Equity = 0.0525 + 5% = 10.25%

Method 3: Using Bond Yield Plus Risk Premium

Cost of Equity = Yield on Company Bonds + Risk Premium
Cost of Equity = 4% + 6% = 10%

Interpretation:

Depending on the method used, the cost of equity ranges from 10% to 11.4%. Companies often use the CAPM method as it incorporates market risk more comprehensively.
