Subtract the risk-free rate from the market (or index) rate of return. If the market or index rate of return is 8% and the risk-free rate is again 2%, the difference would be 6%. 5. Divide the first difference above by the second difference above. This fraction is the beta figure, typically expressed as a decimal value.

Risk Premium = ra (100,000 x 18 / 100) – rf (100,000 x 3 / 100) = 18,000 – 3000 = 15,000 US$.
