# CAPM Calculator

In finance, the Capital Asset Pricing Model is used to describe the relationship between the risk of a security and its expected return. You can use this Capital Asset Pricing Model (CAPM) Calculator to calculate the expected return of a security based on the risk-free rate, the expected market return and the stock's beta.

## CAPM Formula

The calculator uses the following formula to calculate the expected return of a security (or a portfolio):

E(R i ) = R f + [ E(R m ) − R f ] × β i

Where:

E(R i )  is the expected return on the capital asset,

R f is the risk-free rate,

E(R m )  is the expected return of the market,

β i is the beta of the security i

Example: Suppose that the risk-free rate is 3%, the expected market return is 9% and the beta (risk measure) is 4. In this example, the expected return would be calculated as follows:

E(R i ) = R f + [ E(R m ) − R f ] × β i = 3% + (9% − 3%) × 4 = 27%

E(R i ) = 27%
