The interest rate on the loan is 8.25% per year. The bank doesn’t tell you, but it is compounded quarterly. (a) Find the amount of the monthly loan payments. (b) The amount owed immediately after the 30th payment is
(a) $ 1,056.57
(b) $ 15,753.45
Step-1:Calculation of equivalent monthly interest rate | |||||||
(1+i)^n | = | (1+i)^n | Where, | ||||
(1+i)^3 | = | (1+0.020625)^1 | Quarterly Interest rate | = | 8.25%/4 | ||
(1+i)^3 | = | 1.020625 | = | 0.020625 | |||
1+i | = | 1.020625 | ^(1/3) | ||||
1+i | = | 1.00682827 | |||||
i | = | 0.00682827 | |||||
So, | |||||||
Equivalent monthly interest rate | = | 0.00682827 | |||||
Step-2:Monthly Loan payment calculation | |||||||
Monthly Loan payment calculation | =-pmt(rate,nper,pv,fv) | Where, | |||||
= $ 1,056.57 | rate | = | 0.020625 | ||||
nper | = | 48 | |||||
pv | = | $ 32,000 | |||||
fv | = | 0 | |||||
Step-3:Calculation of money owed after 30th payment | |||||||
Money owed after 30th payment | =pv(rate,nper,pmt,fv) | Where, | |||||
= $ 15,753.45 | rate | = | 0.020625 | ||||
nper | = | 18 | |||||
pmt | = | $ -1,056.57 | |||||
fv | = | 0 |
