Calculation of Loan amount if the balance at end of third year is $15,000 | |||||||
Loan amount = Present value of annuity + Present value of loan amount at end of third year | |||||||
Loan amount = 2000*(1-(1.03^-6)/0.03) + 15000*(1/1.03^6) | |||||||
Loan amount = 2000*(1-(1.03^-6)/0.03) + 15000*(1/1.03^6) | |||||||
Loan amount = 2000*5.41719 + 15000*0.83748 | |||||||
Loan amount | $23,396.65 | ||||||
The loan amount is $23,396.65 | |||||||

We would prepare amortization table for the loan to calculate the balance after last regular payment | |||||||

14 | $93.70 | $1,906.30 | $2,000 | $1,216.88 | |||
Therefore the balance of the loan after last regular payment is $1,216.88 | |||||||

From the amortization above, we can see that for the 6th semi annual payment which is third year payment | |||||||
The interest payment is $495.15 and principal payment is $1,504.85 | |||||||
