Explain how much additional money you would need to add to your monthly payment to pay off your loan in 20 years instead of 25.
The current loan balance is $ 112,242.47. If the loan is paid with the annual compounding interest of 5.75 %, after 25 years the total payment would be approximately $ 454116.
If we pay this amount in 25 years, the annual payment will be:
454116 = X {(1+i) ^ 25 - 1)} /i
454116 = X {(1+0.0575) ^ 25 - 1)} /0.0575
The amount that will be paid in 25 years amortization will be as follows:
