Cost of Equity

The rate of return that a company's shareholders expect for holding stock in that company, used as part of the calculation of the total cost of capital for a firm. It represents the opportunity cost to investors of holding shares. The cost can be calculated by a formula dividing dividends per share by the current market value and adding the dividend growth rate.

Definition

Cost of Equity is the rate of return required by a company’s shareholders for them to invest in the equity of the company. This rate is crucial when calculating the total cost of capital for the firm and signifies the opportunity cost for shareholders, as they could have invested their capital elsewhere. It can be estimated using the formula:

\[ \text{Cost of Equity} = \left( \frac{\text{Dividends per Share}}{\text{Current Market Value per Share}} \right) + \text{Dividend Growth Rate} \]

Examples

  1. Company A: Company A issues dividends of $2 per share annually. The current market value per share is $40, and the dividends grow at an annual rate of 5%. The cost of equity would thus be:

\[ \text{Cost of Equity} = \left( \frac{2}{40} \right) + 0.05 = 0.05 + 0.05 = 0.10 \text{ or } 10% \]

  1. Company B: Suppose Company B has a market share value of $50 with annual dividends per share at $2.50, and a steady growth of dividends at 4% annually. The cost of equity calculation would be:

\[ \text{Cost of Equity} = \left( \frac{2.50}{50} \right) + 0.04 = 0.05 + 0.04 = 0.09 \text{ or } 9% \]
