P = | Regular Payments |
PV = | Loan Amount |
r = | rate of interest |
n = | no of periods |
P = | r (PV) |
1 - (1 + r )-n | |
1200 = | (8%/12)*PV |
1 - (1 / (1 + 8%/12)^360)) | |
1200 = | 0.00666666666666667 * PV |
0.908556628 | |
PV = | 1200 * 0.908556628 / 0.00666666666667 |
PV = | 163540.19 |
LOAN AMOUNT = | 163540.19 |
TOTAL EMI PAID = | 1200 * 30 * 12 |
432000.00 | |
INTEREST = | TOTAL EMI - LOAN AMOUNT |
432000 - 163540.19 | |
268459.81 |
