Total Payments: The total amount paid (both principal and interest) over the life of the loan. The NPER formula is used to calculate the number of payments required to pay off the mortgage, taking into account extra payments.

Number of Payments: This would normally just be 12 months times the Term of the loan, except that making extra payments can result in paying off the mortgage early. Normally, accelerated bi-weekly payments are set up such that each year the total amount of extra payments is equal to one normal monthly payment. To estimate Accelerated Bi-Weekly payments, enter an Extra Payment that is equal to the normal Monthly Mortgage Payment divided by 12. This assumes no penalties for making prepayments. Derived from the amount borrowed, the term of the loan, and the mortgage interest rate.Įxtra Monthly Payment: The extra amount you want to pay towards the principal each month (a regularly scheduled prepayment). Monthly Mortgage Payment (PI): Consists of both principal (P) and interest (I). Initial Monthly Interest: The monthly interest payment will go down each month, but for purposes of comparing the interest to the principal payment, the initial monthly interest payment (and the initial monthly principal) is shown.

For example, to enter "10 years + 3 months", enter the following formula: =10+3/12įor Canadian mortgages, the definition of "Term" is different, so for Canadian mortgages you may want to change this label to "Amortization Period."
