TEACHING EXCEL FOR DATA ANALYSIS: HANDS ON 15 Using specialized functions

 

Using specialized functions

You have a large worksheet that contains the details of dozens of loans. A payment rate for each loan must be calculated according to the terms that have been provided for each. You will use the PMT function and the Function Arguments dialog box to complete this task.

1. Click on the link below to open the Microsoft Excel exercise document you can use to complete this exercise.

2. First, click to select cell G3:

Excel workbook open, Cell G3 selected

3. Next, click Formulas → Financial → PMT:

Excel workbook open, Formulas tab selected, Financial selected, small pane open, PMT option chosen

4. The Function Arguments dialog box appears. Within this dialog box you need to enter all of the arguments. As the interest rate is stored in cell E3, type “E3” into the Rate text box:

Function Arguments dialog window open, "E3" typed in the Rate field

5. As these are annual interest rates and the payments will be monthly, you need to divide this value by 12. Type “/12” following the cell reference in the Rate text box:

Function Arguments dialog box open, "/12" typed in the Rate field as well

6. The next argument is Nper, or the number of payment periods over the life of the loan. This information is contained in cell D3, but it is provided in years. Because you need to enter it as months, type “D3*12” into the Nper text box:

Function Arguments dialog box open, "D3*12" typed in Nper field

7. The next argument is Pv, or present value. This is the amount of money that is being borrowed. This information is contained in cell C3, so type “C3” into the Pv text box:

Function Arguments dialog box open, "C3" typed in Pv field

8. Leave the Fv (Future Value) argument field empty. This argument will default to 0, which is what we want. (This means there will be no part of the loan left outstanding at the end of the payments.) We will also let the Type field default to 0, meaning payments will be due at the end of the payment period. Click OK to create the function:

Function Arguments dialog box open, "OK" button selected

9. You now have a result in the cell G3. You will also see the PMT function in the Formula Bar:

Excel wordbook open, you can see the result in the Cell G3 and inside the Formula Bar

10. Now it is time to enter this formula for the rest of the data rows. To do this, click cell G3 to make it active, and then drag the AutoFill handle in the lower right corner of the cell down to G94:

Excel workbook open, Cell G3 selected, AutoFill dragged and handled in the lower right corner of the Cell down to G94

11. Release the mouse button. You will see that the loan payments for each entry have been calculated:

Excel wordbook open, the mouse button was released, the loan payments for each entry have been calculated

12. Save the current workbook as Activity 1-2 Complete and then close Microsoft 365 Excel to complete this exercise.
