    ' Define money format.
    Dim Fmt As String = "###,###,##0.00"
    ' Usually 0 for a loan.
    Dim FVal As Double = 0
    PVal = CDbl(InputBox("How much do you want to borrow?"))
    APR = CDbl(InputBox("What is the annual percentage rate of your loan?"))
    If APR > 1 Then APR = APR / 100 ' Ensure proper form.
    TotPmts = CDbl(InputBox("How many monthly payments will you make?"))
    Response = MsgBox("Do you make payments at the end of month?", MsgBoxStyle.YesNo)
    If Response = MsgBoxResult.No Then
        PayType = DueDate.BegOfPeriod
    Else
        PayType = DueDate.EndOfPeriod
    End If
    Payment = Pmt(APR / 12, TotPmts, -PVal, FVal, PayType)

    MsgBox("Your payment will be " & Format(Payment, Fmt) & " per month.")
