In this article, we will simplify the cost of equity formula in a way that even non-finance professionals can understand. So, don’t worry, we’ve got you covered!

What Is Cost of Equity?

The cost of equity is the return that a company expects from a financial investment. This can be determined through various methods such as the dividend discount model, capital asset pricing model, or bond yield plus risk premium. Knowing the cost of equity is crucial in determining a company’s capital structure and evaluating potential investments.

Why Is Cost of Equity Important?

The importance of the cost of equity lies in its role in determining the minimum return expected by investors, which in turn influences a company’s financial decisions and ultimately its stock price. Recognizing the significance of the cost of equity aids in evaluating potential investments, setting performance goals, and instilling confidence in shareholders.

What Is the Cost of Equity Formula?

The cost of equity formula, also known as the return on equity, is used to calculate the minimum rate of return expected by stockholders based on a company’s risk, the current risk-free rate, and market return. It is represented as: Cost of Equity = (Dividends per Share / Current Stock Price) + Growth Rate of Dividends.

In the world of finance, the cost of equity formula has been a vital tool for investors and financial analysts in determining the expected rate of return for stockholders.

What Are the Components of the Cost of Equity Formula?

The components of the cost of equity formula include:

  • The risk-free rate, which represents the return on a risk-free investment.
  • Beta, which measures the volatility of a stock.
  • Market risk premium, which reflects the expected excess return from the overall market.

A helpful tip is to regularly update these components using current market data to ensure accurate calculations of the cost of equity.

How to Calculate the Cost of Equity?

  • Calculate the cost of equity using the dividend growth model: Cost of Equity = (Dividends per share / Current market value of stock) + Dividend growth rate
  • Utilize the capital asset pricing model (CAPM) to find the cost of equity: Cost of Equity = Risk-free rate + Beta * (Market rate of return – Risk-free rate)
  • Assess the bond yield plus risk premium to calculate the cost of equity: Cost of Equity = Bond yield + Risk premium

The concept of calculating the cost of equity has been around since the early 20th century, originating from the works of financial theorists exploring different equity valuation models.

What Are the Different Methods for Calculating the Cost of Equity?

The different methods for calculating the cost of equity include:

  • Capital Asset Pricing Model (CAPM)
  • Dividend Discount Model (DDM)
  • Bond Yield Plus Risk Premium
  • Earnings Capitalization Model

What Are the Assumptions and Limitations of the Cost of Equity Formula?

The cost of equity formula relies on several assumptions and has certain limitations that need to be considered.


  • The formula assumes that the dividends will grow at a constant rate, which may not always reflect real-world scenarios.


  • It does not account for market fluctuations, changes in interest rates, or company-specific events that can impact the cost of equity.

Therefore, it is advisable to use the cost of equity formula alongside other valuation methods for a comprehensive financial analysis that takes into account all potential factors.
