You can create all kinds of financial calculators in Visual Basic easily as long as long you know the relevant formulas.<\/p>\n

For example, you can create a future value calculator using the following formula:<\/p>\n

FV = PV * (1 + i \/ 100)n<\/sup><\/p>\n

FV=Future Value<\/p>\n

PV=Present Value<\/p>\n

i=Interest<\/p>\n

n=Number of periods<\/p>\n

You simply create a function for the future value, as follows:<\/p>\n

Private Function FV(pv As Single, i As Single, n As Integer) As Double
\nFV = pv * (1 + i \/ 100) ^ n
\nEnd Function<\/p>\n

You then write code for a button where it can compute the future value when the user clicks on the button, as follows:<\/p>\n

Private Sub BtnCal_Click(sender As Object, e As EventArgs) Handles BtnCal.Click<\/p>\n

Dim FutureVal As Single
\nDim PresentVal As Single
\nDim interest As Single
\nDim period As Integer<\/p>\n

PresentVal = TxtPV.Text
\ninterest = TxtInt.Text
\nperiod = TxtN.Text
\nFutureVal = FV(PresentVal, interest, period)
\nLblFV.Text = Format(FutureVal, “$#,##0.00”)<\/p>\n

End Sub<\/p>\n
