Today is Sept. 1, 2009. Starting today you plan to invest $1000 every year, first deposit today and last deposit on Sept. 1, 2025. After that, you plan to leave the money in the same account until Sept. 1, 2030. However, the interest rate is 8% compounded quarterly until your last deposit and only 7% compounded annually after that. How much money will you have in your account on Sept. 1, 2030?
a. $34,504.14
b. $35,504.14
c. $48,393.84
d. $49,005.74
e. None of the above
Since rate of interest given is compounded quarterly, we have to convert the rate | |||||||
to effective rate annually using (1+r/n)^n-1 | |||||||
Here r = 8%, n = 4 | |||||||
(1+.02)^4-1 | |||||||
8.2432% | so effective rate is 8.2432 | ||||||
From Sep 1, 2009 to Sep 1, 2025, there is 17 years of deposit | |||||||
Using Future value of annuity formula | |||||||
FVA = A x[ (1+r)^t-1]/r | |||||||
Here, A = 1000 | |||||||
r = 8.243216% | |||||||
t = 17 | |||||||
FVA = 1000 x[ (1+8.243216%)^17-1]/8.243216% | |||||||
FVA = 1000 x 34.50414 | |||||||
FVA = 34,504.14 | |||||||
Now this value is further invested for 5 years | |||||||
FV = P(1+r)^t | |||||||
Here P = 34504.14 | |||||||
r = 7% | |||||||
t = 5 | |||||||
FV = 34504.14(1+.07)^5 | |||||||
FV = 48,393.84 | Option C is correct | ||||||
