2. 

   2

   Select Blank Workbook. This will open a new Excel spreadsheet.

   Create your «Categories» column. This will go in the «A» column. To do so, you should first click and drag the divider between columns «A» and «B» to the right at least three spaces so you don’t run out of writing room. You will need eight cells total for the following categories:

   • Loan Amount $
   • Annual Interest Rate
   • Life Loan (in years)
   • Number of Payments per Year
   • Total Number of Payments
   • Payment per Period
   • Sum of Payments
   • Interest Cost

4.

   Enter your values. These will go in your «B» column, directly to the right of the «Categories» column. You’ll need to enter the appropriate values for your mortgage.

   • Your Loan Amount value is the total amount you owe.
   • Your Annual Interest Rate value is the percentage of interest that accrues each year.
   • Your Life Loan value is the amount of time you have in years to pay off the loan.
   • Your Number of Payments per Year value is how many times you make a payment in one year.
   • Your Total Number of Payments value is the Life Loan value multiplied by the Payments Per Year value.
   • Your Payment per Period value is the amount you pay per payment.
   • Your Sum of Payments value covers the total cost of the loan.
   • Your Interest Cost value determines the total cost of the interest over the course of the Life Loan value.

5. 

   5

   Figure out the total number of payments. Since this is your Life Loan value multiplied by your Payments Per Year value, you don’t need a formula to calculate this value.

   • For example, if you make a payment a month on a 30-year life loan, you would type in «360» here.

6. 

   6

   Calculate the monthly payment. To figure out how much you must pay on the mortgage each month, use the following formula: «= -PMT(Interest Rate/Payments per Year,Total Number of Payments,Loan Amount,0)».

   • For the provided screenshot, the formula is «-PMT(B6/B8,B9,B5,0)». If your values are slightly different, input them with the appropriate cell numbers.
   • The reason you can put a minus sign in front of PMT is because PMT returns the amount to be deducted from the amount owed.

7. 

   7

   Calculate the total cost of the loan. To do this, simply multiply your «payment per period» value by your «total number of payments» value.

   • For example, if you make 360 payments of $600.00, your total cost of the loan would be $216.000.

8. 

   8

   Calculate the total interest cost. All you need to do here is subtract your initial loan amount from the total cost of your loan that you calculated above. Once you’ve done that, your mortgage calculator is complete.

   Create your Payment Schedule template to the right of your Mortgage Calculator template. Since the Payment Schedule uses the Mortgage Calculator to give you an accurate evaluation of how much you’ll owe/pay off per month, these should go in the same document. You’ll need a separate column for each of the following categories:

   • Date — The date the payment in question is made.
   • Payment (number) — The payment number out of your total number of payments (e.g., «1», «6», etc.).
   • Payment ($) — The total amount paid.
   • Interest — The amount of the total paid that is interest.
   • Principal — The amount of the total paid that is not interest (e.g., loan payment).
   • Extra Payment — The dollar amount of any extra payments you make.
   • Loan — The amount of your loan that remains after a payment.

2. 

   2

   Add the original loan amount to the payment schedule. This will go in the first empty cell at the top of the «Loan» column.

3. 

   3

   Set up the first three cells in your «Date» and «Payment (Number)» columns. In the date column, you’ll input the date on which you take out the loan, as well as first two dates upon which you plan to make the monthly payment (e.g., 2/1/2005, 3/1/2005 and 4/1/2005). For the Payment column, enter the first three payment numbers (e.g., 0, 1, 2).

4. 

   4

   Use the «Fill» function to automatically enter the rest of your Payment and Date values. To do so, you’ll need to perform the following steps:

   • Select the first entry in your Payment (Number) column.
   • Drag your cursor down until you’ve highlighted to the number that applies to the number of payments you’ll make (for example, 360). Since you’re starting at «0», you’d drag down to the «362» row.
   • Click Fill in the top right corner of the Excel page.
   • Select Series.
   • Make sure «Linear» is checked under the «Type» section (when you do your Date column, «Date» should be checked).
   • Click OK.

   Select the first empty cell in the «Payment ($)» column.

6. 

   6

   Enter the Payment per Period formula. The formula for calculating your Payment per Period value relies on the following information in the following format: «Payment per Period<Total Loan+(Total Loan*(Annual Interest Rate/Number of Payments per Year)),Payment per Period,Total Loan+(Total Loan*(Annual Interest Rate/Number of Payments per Year)))».

   • You must preface this formula with the «=IF» tag to complete the calculations.
   • Your «Annual Interest Rate», «Number of Payments per Year», and «Payment per Period» values will need to be written like so: $letter$number. For example: $B$6
   • Given the screenshots here, the formula would look like this: «=IF($B$10<K8+(K8*($B$6/$B$8)),$B$10,K8+(K8*($B$6/$B$8)))» (sans the quotation marks).

7. 

   7

   Press ↵ Enter. This will apply the Payment per Period formula to your selected cell.

   • In order to apply this formula to all subsequent cells in this column, you’ll need to use the «Fill» feature you used earlier.

8. 

   8

   Select the first empty cell in the «Interest» column.

9. 

   9

   Enter the formula for calculating your Interest value. The formula for calculating your Interest value relies on the following information in the following format: «Total Loan*Annual Interest Rate/Number of Payments per Year».

   • This formula must be prefaced with a «=» sign in order to work.
   • In the screenshots provided, the formula would look like this: «=K8*$B$6/$B$8» (without quotation marks).

10. 

    10

    Press ↵ Enter. This will apply the Interest formula to your selected cell.

    • In order to apply this formula to all subsequent cells in this column, you’ll need to use the «Fill» feature you used earlier.

11. 

    11

    Select the first empty cell in the «Principal» column.

12. 

    12

    Enter the Principal formula. For this formula, all you need to do is subtract the «Interest» value from the «Payment ($)» value.

    • For example, if your «Interest» cell is H8 and your «Payment ($)» cell is G8, you’d enter «=G8 — H8» without the quotations.

13. 

    13

    Press ↵ Enter. This will apply the Principal formula to your selected cell.

    • In order to apply this formula to all subsequent cells in this column, you’ll need to use the «Fill» feature you used earlier.

14. 

    14

    Select the first empty cell in the «Loan» column. This should be directly below the initial loan amount you took out (e.g., the second cell in this column).

15. 

    15

    Enter the Loan formula. Calculating the Loan value entails the following: «Loan»-«Principal»-«Extra».

    • For the screenshots provided, you’d type «=K8-I8-J8» without the quotations.

16. 

    16

    Press ↵ Enter. This will apply the Loan formula to your selected cell.

    • In order to apply this formula to all subsequent cells in this column, you’ll need to use the «Fill» feature you used earlier.

17. 

    17

    Use the Fill function to complete your formula columns. Your payment should be the same all the way down. The interest and loan amount should decrease, while the values for the principal increase.

18. 

    18

    Sum the payment schedule. At the bottom of the table, sum the payments, interest, and principal. Cross-reference these values with your mortgage calculator. If they match, you’ve done the formulas correctly.

    • Your principal should match up exactly with the original loan amount.
    • Your payments should match the total cost of the loan from the mortgage calculator.
    • Your interest should match the interest cost from the mortgage calculator.

• The «-» sign in front of the PMT function is necessary, or else the value will be negative. Also, the reason the interest rate is divided by the number of payments is because the interest rate is for the year, not month.

• To AutoFill the date using Google Dogs spreadsheet, type the date in the first cell and then a month forward in the second cell, then highlight both cells and do the AutoFill as described above. If AutoFill recognizes a pattern, it will AutoFill in for you.

• Try building the table like the example first, inputting the example values. Once everything checks out and you’re sure the formulas are right, input your own values.
