Produces the principal remaining at the end of a fixed rate amortization period.
|Amortization_CFpub (171000 ; 6.95 ; 300 ; 60; "BMD" )
Use this function to calculate the Principal at the end of a fixed payment period in a mortgage.
This is a tail-recursion function that accepts the following parameters:
principal - This value is the opening balance of the mortgage.
interest - This is the annual interest rate entered in full numbers i.e. 6.95 for 6.95%.
periods - The function is expecting this to be in months i.e. 12 for one year 360 for 30 years.
payment - Make sure to supply the payment using the same principal, interest and periods.
term - This value is supplied externally and should not exceed the total number of periods.
Notes: The interest is divided by 12 to derive the monthly interest rate and then by 100 to derive the actual percentage.
