Alter the Monthly Payment Using Goal Seek
After you enter the PMT formula, use Goal Seek to peek into different data options. In this tutorial, you’ll see how Goal Seek is used to show the change in the total number of payments to be made when the monthly payment is lowered. We’ll reduce the monthly payment to $3000.00 to see the difference in the number of payments.
