You want to have $45000 to send a child to college in 10 years. Your bank offers a college savings account that pays an APR of 4.2% compounded monthly.
a. How much would you need to deposit monthly to reach your goal?
b. Write the first four lines of the amortization table for this investment.
(a) We find the monthly deposit using 'PMT' function in excel
PMT = PMT(0.042/12,120,0,45000)
Here, Rate = 4.2% / 12 ( Since the rate is compounded monthly)
nper = 120 ( The number of periods = 10 years*12 months = 120)
PV = 0
FV= 45000
we get PMT = -$302.39
ie. $302.39 is to be deposited monthly to reach the goal
