In order to calculate the increase in the monthly payment amount we would have to make the following calculation:
increase in the monthly payment amount=installment increase-installment
installment=(loan amount/1,000)*rate of interest
installment=($120,000/1,000)*4
installment=$480
installment increase=(loan amount/1,000)*rate of interest
installment increase=($120,000/1,000)*5.5
installment increase=$660
increase in the monthly payment amount=$660-$480
increase in the monthly payment amount=$180
The increase in the monthly payment amount is $180
