Step-1:Calculation of present value of annuity | |||||||||||
Present Value of annuity | = | Annuity x Present Value of annuity of 1 | |||||||||
= | $ 50,000 | x | 10.6036 | ||||||||
= | $ 5,30,179.96 | ||||||||||
Working: | |||||||||||
Present Value of annuity of 1 | = | ((1-(1+i)^-n)/i)*(1+i) | Where, | ||||||||
= | ((1-(1+0.08)^-20)/0.08)*(1+0.08) | i | 8% | ||||||||
= | 10.6036 | n | 20 | ||||||||
Step-2:Calculation of present value of above amount | |||||||||||
Present Value of above amount | = | Above Amount x Present Value of 1 | |||||||||
= | $ 5,30,179.96 | x | 0.3152 | ||||||||
= | $ 1,67,134.83 | ||||||||||
Working: | |||||||||||
Present Value of 1 | = | (1+i)^-n | Where, | ||||||||
= | (1+0.08)^-15 | i | 8% | ||||||||
= | 0.3152 | n | 15 | ||||||||
Thus, Required investment today is | $ 1,67,134.83 | ||||||||||
