QUESTION
Your father is 50years old now and his plan is to retire exactly at the age of 60.His goal is to create a fund that will allow him to receiveRs15,00,000 at the time of retirement so that he can start a smallbusiness. He has searched the market and is confused between thetwo options:Option 1: T
This is similar to calculating Annuity of 10 Yrs withInt rate = INT. case A. FV of annuity =FV= Rs 15,00,000,Payment PMT = 9000. Period = 10 yrs. Payments are 6 monthly. Soevery year will have 2 payments. So No of periods Nper = 10*2=20.We need to find Interest rate INT. Present value PV = 0 Formula is FVAn = PMT(FVIFAi,n)However we wil luse Excel Rate function.Rate = RATE(nper, PMT, PV, FV)ie Rate =RATE(10*2,-9000,0,1500000) = 19.06% As we are making a payment, it is a cash outflow & hencehas a negative sign. Case B. FV of annuity =FV= Rs 15,00,000, Payment PMT =9000. Period = 10 yrs. Payments are 4 monthly. So every year willhave 12/4=3 payments. So No of periods Nper = 10*3=30. We need tofind Interest rate INT. Present value PV = 0 Formula is FVAn = PMT(FVIFAi,n)However we wil luse Excel Rate
e = RATE(nper, PMT, PV, FV)ie Rate =RATE(10*3,-2000,0,1500000)= 17.73% As we are making a payment, it is a cash outflow & hencehas a negative sign. Now we may think that Option A is better. However lets see thePayments made in both options.In Option A, nper = 10*2= 20 payments of 9000 each = 20*9000 =1,80,000In Option B, nper = 10*3 = 30 payments of 2000 each = 30*2000= 60,000 Thus we can say that Option B is better as it givesthe same reqd Maturity value of Rs 15,00,000 but at a lowercontribution of rs 60,000. This is magix ofcompounding.
