No, not with a formula, but it is possible to do what you want with VB event
code. Give this a try and see if you can use it or not. Right click on the
tab at the bottom of the worksheet, select View Code from the popup menu
that appears, copy/paste this code into the code window that appeared...
Private Sub Worksheet_Change(ByVal Target As Range)
With Target
If .Column = 6 Then 'Monitor changes in Column F
With .Offset(, 1) 'Puts output in Column G (one to right of Column F)
.Value = "The current tax rate1 is " & 100 * Target.Value & "%"
.Characters(21, 1).Font.Superscript = True
End With
End If
End With
End Sub
Now, go back to your worksheet and enter a value in Column F... the output
will be placed in Column G. The above code assumes values are placed in
Column F manually as opposed to having its values derived from formulas.
