This is the payment number that your prepayments will begin with. For a one time payment, this is the payment number that the single prepayment will be included in. All prepayments of principal are assumed to be received by your lender in time to be included in the following month's interest calculation. If you choose to prepay with a one-time payment for payment number ZERO, the prepayment is assumed to happen before the first payment of the loan.
