Cumulative subtotals in Excel

I have the following code to run subtotals

    Range("A3").Select
    Range(Selection, Selection.End(xlDown)).Select
    Range(Selection, Selection.End(xlToRight)).Select
    Selection.Subtotal GroupBy:=1, Function:=xlSum, TotalList:=Array(5, 6, 7, 8, 9, _
        13, 14, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30), Replace:=True, _
        PageBreaks:=False, SummaryBelowData:=True
    Range("A1").Select

Open in new window


I want to do the cumulative sum from Column 21 to 29

So the value in column 21 should be

(subtotal 20 + subtotal 21) = New value in column 21

The value in columns 22 should be

New value in column 21 + subtotal 22

And so on....

There is no cumulative function in the group subtotal command, however, what happens as you probably know is when that command is executed, Excel goes in and inserts rows/columns adding the subTotal() function.

So at this point, you merely need to go through that function row/column and update it.

Do you have a brief example spreadsheet that goes with this code?  I can better/more quickly help with this conversion if you'd post one.

Thanks,

Dave

That's from U to AC?  I don't speak column numbers, so just confirming...

I think that's right.

Here's your code:
Option Explicit

Sub cumlSubtotals()
Dim wkb As Workbook
Dim wks As Worksheet
Dim lastRow As Long
Dim r As Range
Dim rRow As Range
Dim rng As Range

    Set wkb = ThisWorkbook
    Set wks = wkb.Sheets("Dashboard")
    
    lastRow = wks.Range("A" & wks.Rows.Count).End(xlUp).Row
    
    Set rng = wks.Range(wks.Range("U4:AC4"), wks.Range("U" & lastRow, "AC" & lastRow))
    
    For Each rRow In rng.Rows
        For Each r In Range(rRow.Address)
            If Not r.Formula Like "=SUBTOTAL*" Then 'assume entire row to find has the subtotals, so save time skipping out if not
                Exit For
            Else 'found the subtotal row
                r.Formula = "=" & r.Offset(, -1).Address & " + " & Right(r.Formula, Len(r.Formula) - 1)
            End If
        Next r
    Next rRow
End Sub

Open in new window
