To enter a formula in F2 manually, you can nest up to 7 IF statements (in
Excel 2003 & earlier) like this:
=IF(A2=1,B2*12*0.67,IF(A2=2,B2*12,IF(A2=3,750,0)))
To populate F2 using VBA, you could use something like:
Sub Populate_F2()
Select Case Range("A2").Value
Case 1
Range("F2").Formula = "=B2*12*.67"
Case 2
Range("F2").Formula = "=B2*12"
Case 3
Range("F2").Formula = "=750"
Case Else
'do nothing
End Select
End Sub
