◉ 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*0.065/12
◉ 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
