^^ How to calculate payment amount for a loan
In the cell next to the word payment enter: =PMT(rate [select the field with the interest
rate]/12 [you put /12 because its monthly and there are 12 months in a year], nper
[select the field with the term], pv [select the field with the principal value] - this will
produce the results
Example: =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. [3 points]
In the proper cell do the following: ={select the field mark balance}*{select field marked
interest rate - be sure to add a $ in the field because you do not want the interest rate to
change at all}/12
EXAMPLE: =F19*C$13/12
