In cell C2 type:
=now()

FormattingEdit

Format the first section of your spreadsheet with:

  • an outside border
  • column dividers
  • a fill color
    • Go to the home tab
    • go to the font group
    • click on the borders drop down button
    • choose more borders
  • make sure all colors go together and you can read the text

Format the data as the proper type

  • Dollars
    • Price
    • Down payment
    • Loan amount
    • Monthly payment
    • Total interest
    • Total cost
  • Percent
    • Rate
  • General number
    • Years
  • Date
    • Date

Enter Loan DataEdit

Find a Car you want to purchase and the price

  • go to Kelley Blue Book
    • Find a NEW car you want to buy
    • Find the price
  • go to BankRate.com
    • Find the interest rate for a car loan
    • Remember the number of years for that interest rate
  • Determine if you have any money to put as a down payment NOW
  • Type in the data you have collected into your spreadsheet
    • C3 = name of car you are purchasing
    • C4 = Price for the car
    • C5 = down payment if you have one, 0 if you don't
    • E2 = interest rate for the car loan
    • E3 = number of years for the loan

Create cell Global NamesEdit

  • Click on the cell you wish to name - C4
  • Go to the Formulas tab
  • Go to the Define Names group
  • Click on Define Name
  • Make sure the name is what you want and click OK
    • C4 = Price
    • C5 = Down_Payment
    • C6 = Loan_Amount

etc...

Compute loan amountEdit

The amount of a loan you need to take out is the price of the car minus the amount you will pay when you purchase the car or the down payment.

  • go to cell C6
  • = price - down_payment

or

  • = C4 - C5

Determine the monthly paymentEdit

The monthly payment is how much you will pay each month to pay off the price of the car. This is computed with the interest rate of the loan, the years you will take to pay off the loan, and the total loan amount.

  • go to cell E4
  • -pmt(rate/12, 12*years, loan_amount

or

  • -pmt(E2/12, 12*E3, C6

Determine the total interestEdit

The total interest is the total amount the bank is going to make on loaning you the money to purchase your car. For this computation you will need to know how much the loan amount was, and how much you paid in total over the years. That is figured by taking the years times 12 to find the months, and then multiplying by the monthly payment.

  • go to cell E5
  • =12*years*monthly_payment-loan_amount

or

  • =12*E3*E4-C6

Determine the total CostEdit

The total cost of the car is how much you paid including the down payment and interest. This is figured by adding the price of the car with the total interest.

  • go to cell E6
  • =price+total_interest

or

  • =C4+E5

Analyze your dataEdit

  • Go back to kelly blue book
  • find the price of the same car that is one year old
  • Go back to BankRate.com
  • find the interest rate for a used car
  • Change your data
  • Analyze the difference in how much total you pay for the used car versus a new car

Interest Rate ScheduleEdit

TitlesEdit

  • B7 = Interest Rate Schedule
    • format to same fonts as B1
    • center across B7:E7
  • B8 = Rate
  • C8 = Monthly Payment
  • D8 = Total Interest
  • E8 = Total Cost

make all titles bold

Create a series with the fill handleEdit

  • B10 = 4.00%
  • B11 = 4.25%
  • select cells B10:B11
  • use the fill handle to drag down until you reach 8.00%

Add Initial ValuesEdit

  • C9 = E4
  • D9 = E5
  • E9 = E6

Define the Data TableEdit

  • select B9:E26
  • go to the Data tab
  • go to the Data Tools group
  • click on the what-if analysis drop down
  • choose Data Table
  • click in the column Input Cell
  • click on the rate from cell E2
  • click on OK

FormatEdit

  • select cells B8:E26
  • shade and border similar to the section above but a different color

Conditional FormattingEdit

  • select B10:B26
  • go to the HOME tab
  • go to the styles group
  • click on the conditional formatting drop down
  • click on Highlight cell rules - equal to
  • click in the format cells that are EQUAL TO
  • click on E2
  • click on OK

Change the rate in cell E2 and watch the color section change.
Notice the color rate changes, but the values in the data table does not. You would have to re-select the cells and re do the data table steps.
