Sam gets deposits a total of $3500 every three months to the bank which earns a 6.5% p/a. After five years how much will he have in his account?

Ren wants to buy a new car that costs $26255, so, he would deposit money into his savings account with an interest rate of 3.9% p/a compounded every 4 months, this has been going on for two years now. Determine Renâ€™s regular payment to the bank?

For Sam:

Use

F=R((1+i)^n-1)/i

F=future value

R=payment per period, $3500

i=interest, 0.065/4=0.01625

n=number of periods, 5*4=20

F=$81936 approx.

For Ren

Use the same formula for Sam, except

F=26255, i=0.013, n=2*3=6,

Find R. I get approx. $4236.
