  • Money (capital) needed to run a company comes from either borrowing (debt) or the owners’ money (equity).


  • The COST of capital is either the interest payment on the debt, or the required profit that the owners want in return for their investment (in MBA bullshit language: “expected return”).



  • When you COMBINE BOTH the interest rate of debt AND the ‘expected return’ of the investors/owners, we get the total cost of capital.


  • If the cost of debt (e.g. interest) and cost of equity (expected return) are different, then we have to get an AVERAGE of the two to get our COST OF CAPITAL


  • Cost of capital is expressed as a percentage; because it’s compared to the total capital (as a percentage of the total capital).  Just like bank loan interest is expressed as a percentage of  your total loan.


  • What if your company has more debt vs. equity, OR vice versa? Then our formula must give more importance or ‘WEIGHT’ to whichever is bigger; and must give LESS weight to whichever is SMALLER.  Thus, we have the WACC or Weighted Average Cost of Capital concept.


  • This is the basic WACC or Weighted Average Cost of Capital Formula:

WACC = (Debt Proportion)(Cost of Debt %)(1 – tax rate %) + (Equity Proportion)(Cost of Equity %)

  • To understand this formula step-by-step in action, watch my free video below.

    I do not understand the last part: Why do I compare the cost of capital to a project’s return rate? One is the cost (I take X money and pay y interest/ return) and one is earning (I pay X for a project and take Y money in return). How can that be useful?

    Thanks in advance!

      Hi, not sure I understand your 2nd sentence.. but your project’s rate of return is how much you earn, and your cost of capital is the expense of the money you’re using for your project. So your rate of return should be higher than it.

    I came across this website yesterday and I have since found it very straight forward. I now have more knowledge about some of the financial concepts that I had much difficulty in understanding.

    Can you please specify where to find the step by step solution to the WACC Exam type of Questions?

    I have an exam question that includes the concept of covariance and variance and corporate bonds as well as the expected return on the stock exchange. I am not sure of how to go about the question. Can you please help?

    Hi David, thanks for the explanations…easy to really get the calculations. But my interest would be to figure out how to get the risk premium for the cost of equity?where can I find it for a company when it is not stated on its annual report?

    Many thanks.

    • David

      Reply Reply 23 April 2016

      @Nas Risk premium is basically the difference between the general stock market’s average return and the risk-free interest of a bank deposit… so if the stock market’s general return is 8%/year and the bank deposit rate is 1%/year, then risk premium is 8%-1% = 7%. For particular stock, it would depend on how risky that specific company is compared to the stock market. If that stock is 2X as risky as the general stock market (Beta = 2.0) then the risk premium for that stock would be 7% x 2 = 14%.
