A company's equity beta is 1.2, the risk-free rate is 6% and the expected market return is 12%. Using CAPM, what is the cost of equity?

Under CAPM the cost of equity is the risk-free rate plus beta times the market risk premium. That is 6% plus 1.2 times 6%, which equals 13.2%.

  1. A12.0%
  2. B13.2%Correct
  3. C14.4%
  4. D7.2%
  5. 18.0%

Explanation

Cost of equity = 6% + 1.2 x (12% - 6%) = 6% + 7.2% = 13.2%. Option 14.4% wrongly adds beta times the full market return minus nothing else; 7.2% omits the risk-free rate.
