Solution:
Assume Loan amount = $100,000
Let Interest rate = 12%, Monthly rate of interest = 1%
Number of month to pay back = 12 months
a) Monthly payment amount = Loan amount / Cumulative PV factor at 1% for 12 periods
= $100,000 / 11.25508 = $8,885

| 1 | $8,885.00 | $1,000.00 | $7,885.00 | $92,115.00 |
| 2 | $8,885.00 | $921.15 | $7,963.85 | $84,151.15 |
| 3 | $8,885.00 | $841.51 | $8,043.49 | $76,107.66 |
| 4 | $8,885.00 | $761.08 | $8,123.92 | $67,983.74 |
| 5 | $8,885.00 | $679.84 | $8,205.16 | $59,778.58 |
| 6 | $8,885.00 | $597.79 | $8,287.21 | $51,491.36 |
| 7 | $8,885.00 | $514.91 | $8,370.09 | $43,121.27 |
| 8 | $8,885.00 | $431.21 | $8,453.79 | $34,667.49 |
| 9 | $8,885.00 | $346.67 | $8,538.33 | $26,129.16 |
| 10 | $8,885.00 | $261.29 | $8,623.71 | $17,505.45 |
| 11 | $8,885.00 | $175.05 | $8,709.95 | $8,795.51 |
| 12 | $8,885.00 | $87.96 | $8,795.51 | $0.00 |
b: Interest expense would be included in first payment = $1,000
c. Interest expense would be inclueded in last payment = $87.96
d. Total amount repaid over 12 months = $8,885*12 = $106,620
Amount of loan = $100,000
Total interest paid over the term of loan = $106,620 - $100,000 = $6,620
