CAPM & Cost of Equity Calculator Formula Breakdown
Benchmark sovereign yield with zero default risk (typically the 10-Year US Treasury bond yield, currently ~4.2%).
Covariance of the stock's returns relative to the benchmark market index (S&P 500). Measures systematic volatility.
The excess return demanded by rational investors over risk-free bonds to hold equities (typically 5.0% - 6.0%).
The required rate of return equity capital demands, serving as the equity component in WACC valuations.
How to Calculate CAPM Calculator Step-by-Step
Input or automatically fetch the 10-Year Treasury risk-free rate (Rf).
Retrieve the stock's 5-year monthly Beta coefficient relative to the S&P 500.
Establish the long-term historical Equity Risk Premium (ERP = Rm - Rf).
Multiply Beta by the Equity Risk Premium and add the Risk-Free Rate.
Review the Beta sensitivity matrix to evaluate cost of equity under varying market volatility conditions.

Frequently Asked Questions
What is the Capital Asset Pricing Model (CAPM)?
CAPM is a foundational corporate finance theorem developed by William Sharpe that establishes the relationship between systematic risk and expected equity returns.
Why is Cost of Equity essential in stock valuation?
Cost of Equity determines the discount rate applied to equity cash flows (such as FCFE or Dividend Discount Models). An inaccurate cost of equity distorts DCF intrinsic fair value.
What is a typical Cost of Equity for US stocks?
For large-cap US equities with a Beta around 1.0, Cost of Equity typically ranges between 8.5% and 10.5%, depending on prevailing Treasury yields and market risk premiums.
