  • CAPM is just a “model” or formula used to calculate COST OF EQUITY


  • Cost of Equity is how much an investor “wants” to earn for investing in a company which is more risky than a safe bank deposit (or government bond), and (usually) more risky than investing in the general stock market with a bunch of stocks.


  • It’s called a “cost” because that’s how much you should “fairly” pay your investors for investing in your risky company.



  • CAPM assumes that investing in many stocks is safer than investing in just one company’s stock: “don’t put all your eggs in one basket” sorta thing.. this is called “diversified” risk


  • Rationale: An investor would “want” (or “expect”) more income (“return”) for investing in a highly risky company instead of the zero-risk  bank/bond, and also instead of investing in a “medium-risk” general stock market.  Therefore, cost of equity = “expected return”


You calculate Cost of Equity using the CAPM or Capital Asset Pricing Model Formula:

Ke = Rf + B (Rm-Rf)

DON’T panic! It’s MUCH  EASIER than it looks! See this formula step-by-step in action, watch it for free in the video above.

    What a fantastic website. Thank you so much for explaining this in such a simple easy to follow way. It has helped me so much.

    The only thing I got lost on was how did you get to 8.6% on the CAPM calculation as I keep getting 6.72
    because 0.02+1.1(0.08-0.02) = 1.12 x0.06 doesnt it?

      Reply Reply 21 June 2012

      Hello Lisa. You must first multiply the 1.1 with the 0.06 before adding it to the 0.02 🙂
