Suppose your credit card balance is $15 comma 500. The minimum payment is $344, and the annual percentage rate is 19.6%.
a. If you make a constant monthly payment of $344, how long will it take you to pay off the credit card balance?
b. How much interest will you pay if you elect to make the minimum payment?
- Credit Card balance = $15,500
a). Minimum monthly payment = $344
Annual percentage rate(APR) = 19.6%
Calculating the time it will to take to pay off the Loan balance:-
Where, P = Credit card balance = $15,500
r = Periodic Interest rate = 19.6%/12 =1.633%
n= no of periods
EMI = Minimum monthly payment = $344
1.35878868(1.016333)^n - 1.35878868 = (1.016333)^n
0.35878868(1.016333)^n = 1.35878868
(1.016333)^n = 3.78715594
Taking log on both sides..
nLog(1.016333) = Log(3.78715594)
n(0.007036027) = 0.578313188
n = 82.19 monthly payments.
So, it will take 82 monthly payments to pay off the credit card balance.
b). Interest Payment = (Minimum monthly payment*No. of Monthly Payments) - Credit card balance
= ($344*82) -$15500
= $ 12,708
