CAPM Calculator


The Capital Asset Pricing Model (CAPM) explores the relationship that exists between risk and return.

It basically says that investors should be rewarded for the time value of money and the risk that they take.

The CAPM model uses beta to measure the risk of a stock. The time value of money is the “risk free” rate of investment. For example, if you put your money in cash, there would be no risk at a rate of return of around 5.75%. Hence, the risk free rate would be 5.75%.

William Sharpe

The CAPM model is the work of William Sharpe. He outlined the CAPM in his 1970's book “Portfolio Theory and Capital Market”. He later won a Nobel Prize in economics with Harry M Markowitz and Merton M Miller.

The value is an average of analysts forecasts for EPS growth over 5 years which is then averaged.
