The Cost of Common Equity Calculator is a financial tool used to determine the rate of return required by investors who have invested in a company’s common stock. It’s an essential metric for businesses and investors to evaluate the attractiveness of investing in a company’s equity.

**Cost of Common Equity Formula and Variables:**

The formula to calculate the cost of common equity (Ke) is:

$\mathrm{KE}=\frac{D1}{P0}+g$

**Ke**: Cost of common equity, expressed as a percentage (%)**D1**: Expected annual dividends per share ($)**P0**: Current market price per share ($)**g**: Growth rate of dividends, expressed as a decimal

**Importance and Application:**

**Investment Evaluation:**Helps investors assess the attractiveness of investing in a company’s common stock by determining the rate of return they expect to earn on their investment.**Capital Budgeting:**Provides businesses with a benchmark for evaluating potential investment projects and making decisions regarding capital allocation.**Cost of Capital:**The cost of common equity is a component of the company’s overall cost of capital, which is used in financial analysis, budgeting, and investment decision-making processes.

**How to Use:**

- Determine the expected annual dividends per share (D1) based on the company’s dividend policy and financial projections.
- Determine the current market price per share (P0) by referencing financial data or stock market information.
- Determine the growth rate of dividends (g) based on historical data, analyst forecasts, or the company’s growth prospects.
- Apply the formula: Divide the expected annual dividends per share by the current market price per share, then add the growth rate of dividends to calculate the cost of common equity as a percentage.

**Example:** Let’s say a company’s expected annual dividends per share (D1) is $2, the current market price per share (P0) is $50, and the growth rate of dividends (g) is 5%.

$\mathrm{KE}=\frac{2}{50}+0.05$

$\mathrm{KE}=0.04+0.05$

$\mathrm{}$$\mathrm{KE}=0.09$

In this example, the cost of common equity would be 9%.

**Conclusion:** The Cost of Common Equity Calculator is a fundamental tool in finance used by both investors and businesses to assess the rate of return required on investments in common stock. By calculating the cost of common equity, investors can make informed investment decisions, while businesses can evaluate their cost of capital and determine appropriate financing strategies.
