Annuities and compounding Personal Finance Problem: Janet Boyle intends to deposit $340 per year in a credit union for the next 9 years, and the credit union pays an annual interest rate of 10%.
a. Determine the future value that Janet will have in years, given that end-of-period deposits are made and no interest is withdrawn, if
(1) $170 is deposited semiannually and the credit union pays interest semiannually.
(2) $85 is deposited quarterly and the credit union pays interest quarterly.
FV = 4617.02
FV = PMT ((1+i)n - 1 / i
FV =340 x ((1+0.1)9 - 1 / 0.1
FV = 340x (1.3579 / 0.1)
FV = 340 x 13.5795
FV = 4617.02
(1)FV =4782.51
$170 is deposited semiannually and the credit union pays interest semiannually.
FV = PMT ((1+i)n - 1 / i
FV =170 x ((1+0.05)18 - 1 / 0.05
FV = 170 x (1.4066/0.05)
FV =170 x 28.1324
FV =4782.51
(2)FV =4870.62
$85 is deposited quarterly and the credit union pays interest quarterly.
FV = PMT ((1+i)n - 1 / i
FV =85 x ((1+0.025)36 - 1 / 0.025
FV = 85 x (1.4325 / 0.025)
FV = 85 x 57.3014
FV =4870.62
