CAPM Calculator
CAPM Calculator Overview
Calculate expected return using CAPM
The Capital Asset Pricing Model (CAPM) Calculator is a sophisticated financial tool used to estimate the expected return on an investment based on its riskiness relative to the market. It is a cornerstone of modern portfolio theory, widely used by financial analysts and corporate finance professionals to calculate the 'Cost of Equity'.
The model helps investors determine if a stock is worth the risk. It combines the 'Risk-Free Rate' (what you'd get from a safe bond), the asset's 'Beta' (how volatile it is), and the 'Expected Market Return'. The result tells you the minimum return you should demand for holding that risky asset. If the stock's estimated return is lower than the CAPM result, it may be overvalued.
How to Use CAPM Calculator
- Enter the Risk-Free Rate (usually the current 10-year Treasury yield).
- Enter the stock's Beta (available on most finance news sites).
- Enter the Expected Market Return (historical S&P 500 average is ~10%).
- Calculate the Expected Return (Cost of Equity).
Frequently Asked Questions
- What is the Risk-Free Rate?
- It is the theoretical return of an investment with zero risk. In practice, the yield on 10-year U.S. Government Treasury bonds is used as the standard benchmark.
- What does Beta mean?
- Beta measures volatility relative to the market using regression analysis. A Beta of 1.0 means the stock moves with the market. Beta > 1.0 is more volatile (riskier), and Beta < 1.0 is more stable (defensive).
- Why use CAPM?
- It provides a grounded, mathematical framework for pricing risk. It prevents investors from accepting low returns for high-risk assets by quantifying the 'risk premium' they should earn.
- What is the Market Risk Premium?
- It is the difference between the Expected Market Return and the Risk-Free Rate. It represents the extra return investors demand for investing in the stock market instead of risk-free bonds.
