- April 4, 2015 at 3:16 pm #240128Hi John, I am trying to solve one of the questions given in mock exam on this site. Required 24,000 at time 0 
 Generates inflow of 5,000/year for 8 years (first inflow in 1 yrs time)
 I need to calculate IRRMy calculations… (as in the question was not given d.f. I took 10% and 5% to calculate NPV) 0yr (24,000) x 1 = (24,000) 1-8yrs 5,000 x 5,335 = 26,675 
 1yr 5,000 x 0,909 = (4,545)NVP (10%) is (1,870) 0yr (24,000) x 1 = (24,000) 1-8yrs 5,000 x 6,463 = 32,315 
 1yr 5,000 x 0,952 = (4,760)NVP (5%) is (3,555) 10% – 5% = 5% 
 1,870 + 3,555 = 5,425IRR = a + ((NPVa/NPVa-NPVb) x (b-a)) IRR = 5% + ((3,555/5,425) x 5%) = 8.26% And I am not even close to the answer (13%) What am I doing wrong? Thanks, Yana April 5, 2015 at 8:07 am #240162I thank u supose to Use the redeemption value of 100 and discount it at 0.467 at 10% and at 15% (0.233). Your final IRR will give sum thing like 12.9% which when u round of it will give you 13%. 
 Just a try,frm Mac DApril 5, 2015 at 8:23 am #240163Therefore: IRR=10+(2272/2272+1528) (15% – 10%) 
 Then : 10% + 2.989
 Gives ,IRR of 13%April 5, 2015 at 9:57 am #240171Donald: Thanks for answering, but please do not answer in the Ask the Tutor Forum because you are not the tutor 🙂 Yana: Since the first inflow is in 1 years time, the flows are 1 to 8. To get the present value you simply multiply by the 8 year annuity factor. This discounts for 1 to 8 and you don’t need to then subtract 1 year as you have done. 
 So the present value at 10% is 26675 – 24000 = + 2675
