Student Activity
In this activity, you will create a worksheet to
calculate the actual cost of purchasing two new vehicles.
You will have two different payments figured for the two different vehicles.
WHAT TO DO: Create a new Microsoft Excel
worksheet like the one in Example 1
Note: You only need
two vehicles.

Example 2: Microsoft Excel's Periodic Payment Function
Example 3
B 1 Ford Ranger 2 $18500 3 $5000 4 =B2-B3 5 8.25% 6 4 7 12 8 =PMT(B5/B7,B6*B7,-B4) 9 =B3+(B8*B6*B7) 10 =(B6*B7*B8)-B4
This table lists the necessary formula entries. Note that the number of the rows are different than the above example. However, the cell entries are correct and do match the Ford Ranger entries in example 1.
Note that the following instructions refer to example 2.
PMT Function: In Cell B10 paste Microsoft Excel's
PMT function (Periodic Payment Function). Click cell
B10, then choose Function from the Insert menu.
Select Financial from the Function Category list,
then choose PMT from the Function Name list. Click
OK.Type the following cell references in the PMT dialog
box. For Rate (the interest rate per period for the
loan), type =B7/B9; for Nper (the total number of
loan payments), type =B8*B9; for Pv (loan amount),
type =B6. Choose OK.Microsoft Excel returns a negative number to
indicate that you are making a payment.Note: To work with positive numbers on the
worksheet, calculate PMT as follows:
=PMT(rate,nper,-pv)."Total Amount Paid" Formula: In B11, type the
following formula, which will calculate the total
amount paid for a loan: =SUM(B10*(B8*B9)), where
B10=PMT (i.e., the amount paid each payment
period) and B8*B9 =nper (the total number of loan
payments)."Interest Paid" Formula: In B12, type the
following formula which calculates the total amount
of interest paid: =SUM(B11-B6), which is the total
amount paid minus the loan amount.Showing Formulas: To have Microsoft Excel show
formulas, rather than formula results, choose
Options from the Tools menu; click the View tab,
then select the Formulas check box. To display
formula results, clear the check box.Once you format the cell contents of column B,
entering appropriate formulas where necessary, you
can copy cell content and format to columns C and
D using Autofill or Fill Right.What you need to do to complete the assignment?
The length of the loan should be 3, 4 or 5 years. You make up the down payment. However, be certain that your choices are reasonable.
- State where you found the purchase price of each vehicle.
- You need to do this for the two vehicles.
- State where you got the current new-car interest rates.
- You need to insert pictures of the two vehicles.
- One of the two pictures must be a hyperlink to a web site.
- You must save the file in your math folder as "Car.xls"
- You must print a copy of your project displaying the formulas.
