Principal Reduction amount
Amount that will be prepaid on your mortgage. This amount will be applied to the mortgage principal balance, based on the principal reduction type.

Start with payment
This is the payment number that your principal reductions will begin with. For a one time payment, this is the payment number that the single principal reduction will be included in. All principal reductions 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 principal reduction is assumed to happen before the first payment of the loan.
