Internal Rate of Return (IRR)
For Example:
A ) In Jan-2008 We have Invested 100,000,000 $ for that 50% (50,000,000) we took a loan from financial institution and 50% (50,000,000) we invest from our capital.
B) Rate of interest for borrowing (50,000,000) is 8% flat yearly.
C) We need to pay extra (cost) of $ 1,000,000 for incurring cost monthly.
C) We sold out this investment in 120,000,000. in June-2008.
Can anybody guide me to calculate IRR (Internal Rate of Interest).
Also convey with if you have any easy example/function/theory.
Best Regards,
Zakariyya
Dear Zakariyya,
Between January 2008 and June 2008 you registered some cash from your investment?
Or you invested only for speculative matter?

You need to focus on the cash flow items:
The cash flow items are (in chronological order):
- The investment out of pocket (50 MM). (The other 50 MM you receive from the bank and you pay for the invesment so it is 0 at the beginning)
- the interest that you pay monthly (8% divided by 12 months applied to 50 MM = 333.333 per month)
- the 1 MM that you pay (I am assuming at the end)
- the payback of the loan (50 MM) at the end
- the income received (120 MM) at the end
If you put those in order you have:
Month 1: – 50.000.000
Month 2: – 333.333
Month 3: – 333.333
…
Month 6: – 333.333
End: +69.000.000 (-1.000.000 – 50.000.000 +120.000.000)
if you put them in the same column in Excel you will use the IRR Function and get 5.02% per month IRR. If you want to compare that with the rate of interest you need to multiply by 12 so you get aprox 60%
You need to be careful of the timeline (if interest is paid at the beginning or at the end of the period etc)
You can check if IRR is correct by computing the NPV of the project if interest rate is IRR. It should be nil

Simplified approach- if your cash flows incurred at the beginning and end of the year
