MAIN POINTS

    :

  • Rate of return is “how fast” you can get back your money after you invest it. It’s expressed as a percentage per year, forever.

 

  • For example, if you invest $100 and get back $3 per year (forever), then your rate of return is 3% (Because $3 = 3% of $100)

 

  • Internal rate of return is the same as rate of return, except it’s not so easy to figure out like in the $3 example above.  What if you get back $3 on the first year, but another amount in other years? And what if it’s not forever?

 

  • In this case, we figure out this “mystery” rate of return (a.k.a. internal rate of return) using the IRR or Internal Rate of Return Formula:
    0 = CF1(1+irr) + CF2(1+irr)-1 +…+ CFN(1+irr)-n

DON’T panic! It’s much EASIER than it looks. Watch tutorial video below.

  • IRR is used to gauge how “profitable” a business is, taking into account the amount invested in a company or a specific project

 

  • IRR can be compared to cost of borrowing money for capital (or other sources of capital).  For example: if your company’s capital comes from borrowing money from the bank at 5% interest rate, then your IRR should be higher than 5%… if your IRR is only 3%, then you are losing 2% (because 3% IRR less 5% bank interest will leave you with negative -2%)

 

  • IRR can also be compared to your alternative investment choices.  Why will  you do a business project and earn only 3% IRR… if you can instead invest your money in a bank’s fixed term deposit which earns 4%?  You are missing an opportunity to earn an extra 1%.

    Hi, I am enjoying the slides but have a question about IRR. Why would you not know what the bank rate is? Surely ‘r’ will be whatever interest rate you can receive from your bank??

      Hello! Nope, these are 2 different rates in this case. You find out “r” from IRR and then you COMPARE it to the “r” of your bank. If your IRR is higher than your bank’s “r” then you’re gettin a better deal than your bank.

    In my exam a scientific calculator isn’t allowed, how can I work out the rate of return with a regular calculator?

    1. David Avatar

      Unfortunately, you’ll have to do it the slightly longer formula with cashflow on top divided by the (1+r) at the bottom and a positive exponent for the (1+r)

    I am using my laptop calculator in scientific mode however, I cannot get the -0 exponent. What do you suggest?

    Thanks for the wonderful explanation I have one question, when guessing the first “r” why did u chose 14%? I mean , in this question the right IRR was 13% so your guessing was close. how can I do the same thing in the exam? some times IRR is 27% or 6% so how I get a hint of the range of r?

      @Awfa You kinda just make a guestimate in the beginning. Some people use an approximation formula but I don’t recommend it coz it only works with uniform conditions and uniform cashflow

        Thanks David. I wish I can use your way on tomorrow’s exam ! But they told us to use fake PV and a very time consuming method . Thank you again ,your videos are the best .

    Hi David,

    Congratulations for this excellent website that is really helping lots of people just like me to pass their exams. I would like to know why the equation to find the IRR is equal to cero. How do you know it must be equal to cero. Thank you for your help.

    Great, good for non financials to understand what it all means.

    A little too much detail on adding 1 to 0,14, but what the heck, I understand this.

    Thankyou!!!

    Loving your videos; so far the best lecturer among all. Indeed you are very patient and knowledgeable, while explaining this concept. Now,I finally understand what this IRR is all about. I also like how you used very simple examples, that we can easily relate to.

    Appreciate this free video, thus am hoping to buy more materials from your website. I’m taking couple more courses to finish up my BA-in Business! Currently, I’m on this Unv.-Online-program; literally feeling crushing by this Finance Class, until I found your classroom!

    May God Bless!
