Вы можете сделать что-то вроде этого:
Sub SetUpSummarySheet()
Dim ws As Worksheet
Set ws = Worksheets("Summary")
InsertWithHeaderAndFormula ws, "E", "Net Return", "=RC[-2]-RC[-3]"
InsertWithHeaderAndFormula ws, "G", "Blah", "=RC[-1]"
'etc for other solumns
End Sub
'Insert a column in sheet ws, add a header hdr and a formula sForm to extend
' as far down as there are values in ColA
Sub InsertWithHeaderAndFormula(ws As Worksheet, colLetter As String, _
hdr As String, sForm As String)
Dim lastRow As Long
lastRow = ws.Cells(ws.Rows.Count, "A").End(xlUp).Row
ws.Cells(1, colLetter).EntireColumn.Insert Shift:=xlToRight
ws.Cells(3, colLetter).Value = hdr
ws.Cells(4, colLetter).Resize(lastRow - 3, 1).FormulaR1C1 = sForm
End Sub
