3 4. Select cell B15,type =-B10 and then press 4 to change the cell reference to an absolute reference. The amount displayed in cell B15 is the monthly payment converted to a positive number. Because the monthly payment will refer to the value in cell B15 for every row of the amortization table, the reference needs to be an absolute cell reference so that it does not change when the formula is copied to the other rows. 5. Press F, and in cell C15,type =E14*$B$7/12 and press F. The interest payment is equal to the current balance multiplied by the monthly interest rate. The interest rate is an absolute cell reference so that the formula always refers to the value in cell B7 when the formula is copied to other rows. 6. Select cell D15,type =B15-C15 and then press F. The amount of a payment applied to the principal is the payment minus the amount that is applied to interest. 7.
