Excel VBA SUMIF Super slow code - excel

Question

I have SUMIF running really really slow. My data has 14,800 Rows and 39 Columns.
I do the following:
Application.ScreenUpdating = False
Application.DisplayStatusBar = False
Application.Calculation = xlCalculationManual
Application.EnableEvents = False
ActiveSheet.DisplayPageBreaks = False
EDITED TO ADD more potentially relevant code that may be interacting with the SUMIF command
It may be relevant to the speed issue so I'll mention it. I get the user to open a file from wherever they may have stored the report. The file then stays open. Maybe that is a problem. I don't know if it should be some other way.. like I close it but keep the address in mind or something??
FilterType = "Text Files (*.txt),*.txt," & "Comma Separated Files (*.csv),*.csv," & "ASCII Files (*.asc),*.asc," & "All Files (*.*),*.*"
FilterIndex = 4
Title = "File to be Selected"
File_path = Application.GetOpenFilename(FileFilter:=FilterType, FilterIndex:=FilterIndex, Title:=Title)
If File_path = "" Then
MsgBox "No file was selected."
Exit Sub
End If
Set wbSource = Workbooks.Open(File_path)
Original_Name = ActiveWorkbook.Name
If ActiveSheet.AutoFilterMode Then
ActiveSheet.AutoFilterMode = False
End If
Set wb1 = ActiveWorkbook
Set ws1 = wb1.Worksheets("Sheet1")
With ws1
FinalColumn = .Cells(1, .Columns.Count).End(xlToLeft).Column
FinalRow = .Range("B" & .Rows.Count).End(xlUp).Row
For j = 1 To FinalColumn
If .Cells(1, j).Value = "Effec.Date" Then
Effective_Date_Column = j
ElseIf .Cells(1, j).Value = "FolderId" Then
FolderId_column = j
ElseIf .Cells(1, j).Value = "FolderNotional" Then
FolderNotional_column = j
End If
Next j
'range_Total_Folder_Fixed = .Cells(2, Total_Folder_Column).Address & ":" & .Cells(FinalRow, Total_Folder_Column).Address
range_FolderId_Fixed = .Cells(2, FolderId_column).Address & ":" & .Cells(FinalRow, FolderId_column).Address
range_FolderId_Cell = .Cells(2, FolderId_column).Address(RowAbsolute:=False, ColumnAbsolute:=False)
range_FolderNotional_Fixed = .Cells(2, FolderNotional_column).Address & ":" & .Cells(FinalRow, FolderNotional_column).Address
Everything runs in 8-10 seconds until we come to the lie below. Now the total time jumps to a 150 seconds.
.Range(range_Total_Folder_Fixed).Formula = "=SUMIF(" & range_FolderId_Fixed & "," & range_FolderId_Cell & "," & range_FolderNotional_Fixed & ")"
Am I doing something wrong? Is there a better (more efficient) way to write a general formula?
EDIT: Code generated Raw Formula
Some of the excel worksheet functions in my code:
.Range(range_Isnumber).Formula = "=(RIGHT(" & range_TradeId_cell & ",2)<> ""IB"")*1"
.Range(range_Is_IB).Formula = "=(RIGHT(" & range_TradeId_cell & ",2)= ""IB"")*1"
.Range(range_Exceptions).Formula = "=(SUMIF(" & range_FolderId_Fixed & "," & range_FolderId_Cell & "," & range_Isnumber_fixed & ")= COUNTIF(" & range_FolderId_Fixed & "," & range_FolderId_Cell & "))*1+(SUMIF(" & range_FolderId_Fixed & "," & range_FolderId_Cell & "," & range_Is_IB_fixed & ")= COUNTIF(" & range_FolderId_Fixed & "," & range_FolderId_Cell & "))*1 "
.Range("C13").FormulaR1C1 = "=SUM(IF(FREQUENCY(MATCH([SCL_FL_2013_11_30.xlsx]Rest!R2C2:R2321C2,[SCL_FL_2013_11_30.xlsx]Rest!R2C2:R2321C2,0),MATCH([SCL_FL_2013_11_30.xlsx]Rest!R2C2:R2321C2,[SCL_FL_2013_11_30.xlsx]Rest!R2C2:R2321C2,0))>0,1))"
So Stuff like
Range("I2")=SUMIF($H$2:$H$5,H2,$G$2:$G$5)
Where the data could be like
RowG RowH RowI
Alice 1 4
Alice 3 4
Bob 9 17
Bob 8 17
Dan 2 2
EDIT2 : Implementing Sam's solution, I am getting errors:
Set range_FolderId_Fixed = .Range(.Cells(2, FolderId_column), .Cells(FinalRow, FolderId_column))
Set range_FolderId_Cell = .Range(.Cells(2, FolderId_column),.Cells(FinalRow, FolderId_column))
Set range_FolderNotional_Fixed = .Range(.Cells(2, FolderNotional_column), .Cells(FinalRow, FolderNotional_column))
Set range_Total_Folder_Fixed = .Range(.Cells(2, Total_Folder_Column), .Cells(FinalRow, Total_Folder_Column))
.Range(range_Total_Folder_Fixed).Value = SumIf_func(range_FolderId_Fixed, range_FolderId_Cell, range_FolderNotional_Fixed)
I am getting a type application defined or object defined error in the line below.
.Range(range_Total_Folder_Fixed).Value = SumIf_func(range_FolderId_Fixed, range_FolderId_Cell, range_FolderNotional_Fixed)
I have no idea what to do next.

Answer 1

Ok this is what I came up with
Public Function SumIf_func(rng As Range, _
criteria As Range, _
sumRange As Range) As Variant()
Dim rngArr() As Variant
Dim sumArr() As Variant
Dim criteriaArr() As Variant
Dim returnArr() As Variant
Dim temp As Double
rngArr = rng.Value2
sumArr = sumRange.Value2
criteriaArr = criteria.Value2
If UBound(sumArr) <> UBound(rngArr) Then _
Err.Raise 12345, "SumIf_func", "Sum range and check range should be the same size"
If UBound(sumArr, 2) <> 1 Or UBound(rngArr, 2) <> 1 Then _
Err.Raise 12346, "SumIf_func", "Sum range and check range should be a single column"
ReDim returnArr(1 To UBound(criteriaArr), 1 To 1)
For c = LBound(criteriaArr) To UBound(criteriaArr)
returnArr(c, 1) = Application.WorksheetFunction.SumIf(rng, criteriaArr(c, 1), sumRange)
Next c
SumIf_func = returnArr
End Function
This function takes in three ranges:
The range to check
The range where the criteria are
The range where the values to sum are
The range to check and the sum range should both be the same length and only be 1 column across.
The array that is returned will be the same size as the criteria array..
Here is an example of usage:
Public Sub test_SumIf()
Dim ws As Worksheet
Set ws = Sheet1
Dim rng As Range, sumRng As Range, criteria As Range
Set rng = ws.Range("A1:A100")
Set sumRng = ws.Range("B1:B100")
Set criteria = ws.Range("C1:C10")
ws.Range("D1:D10").Value = SumIf_func(rng, criteria, sumRng)
End Sub
