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.
