Andrew borrows a certain amount of money at 7% effective. He will repay this loan by making payments of 2000 at the end of each year for 15 years, using the amortization method.
Calculate the amount of principal repaid in the 4th payment.
A. Calculation of Present Value (PV) of Annuity(A) :
PV = A * [{(1+rate)time-1}/{rate*(1+rate)time}]
PV = 2000 * [{(1+0.07)15-1}/{0.07*(1+0.07)15}]
PV = 18,215.83
B. Calculation of principal repaid in 4th payment :

Principal Outstanding at the beginning |
Interest @ 7% |

Principal paid in current instalment |
1 | 18215.23 | 1275.07 | 2000 | 17490.30 | 724.93 |
