Calculate the payment amount for the loan in cell C15. Reference the cells containing the
appropriate loan information as the arguments for the function you use. Cells C20-C67 in the
"Payment" column are populated with the payment amount from cell C15. - Answer:
=PMT(C13/12,C12,C11)
Calculate, in cell D20, the interest amount for period 1 by multiplying the balance in period 0
(cell F19) by the loan interest rate (cell C13) divided by 12. Dividing the interest rate by 12
results in the monthly interest rate. This formula is reusable. The interest for a given period is
always the monthly interest rate times the balance from the previous period.
f - Answer: =F19*C$13/12
Copy the Interest amount calcualtion down to complete the "interest" column of the
amortization table. - Answer: Paste down column .
Calculate, in cell E20, the principal amount for period 1. The principal amount is the difference
between the payment amount (cell C20) and the interest amount (cell D20) for period 1.
Construct your formula in such a way that it can be reused to complete the "principal" column
of the amortization table. - Answer: =C20-D20
, Copy the principal amount calculation down to complete the "principal" column of the
amortization table. - Answer: Copy and paste down.
Calculate, in cell F20, the balance for period 1. The balance is the difference between the
balance for period 0 (cell F19) and the principal amount for period 1 (cell E20). This formula is
reusable. The balance is always calculated as the difference between the balance from the
previous period and the principal amount for the current period. - Answer: =F19-E20
Copy the balance amount calculation down to complete the balance column of the amortization
table. - Answer: Copy and paste down.
Calculate, in cell G12, the total amount paid by multiplying the payment amount (cell C15) by
the term of the loan (cell C12). - Answer: =C15*C12
Calculate the total interest paid in cell G13. The total interest paid is the sum of all interest paid
in the "Interest" column of the amortization table. - Answer: =SUM(D20:D67)
Check to see if the total interest calculation in the amortization table is correct. The total
interest paid is also equal to the difference between the total amount paid over the course of
the loan and the original loan amount. Insert a formula into cell G14 to calculate the difference
between the total amount paid and the original loan amount. Notice the negative sign
associated with the original loan amount. This value should equal the total interest calculated
using the amortization table. - Answer: =G12+C11
Assume you have made the first 36 payments on your loan. You want to trade the car in for a
new car. You believe that you can sell your car for $4000. Will this cover the balance remaining
on the car in period 36? Answer either "Yes" or "No" in cell G15 from the drop-down menu. -
Answer: No
Use the HLOOKUP function to complete the "Hourly Wage" column of table 1. Use the
"Employee" column of table 1 as the lookup_value and the "Employee Wage Information"
above table 1 as your reference table. - Answer: =HLOOKUP(D16, E$11:H$12, 2,False)
