Thank you in advance for any helps anyone can provide. My knowledge of VBA is very limited.
I have a list of vba codes that I have to update the cell references every month when new column was added for new month.
I am looking for a way to simplify those codes, so that instead of updating the range (column) for all of them, I only need to update a few.

Is there a way to simplify the codes below?
The range that will be change monthly (move up one column as new column were added for a new month), is the "K" and "H" as in example below. The rows stay the same.
This is referenced to several tables within a worksheets (with headers), that's why some rows were not included (for example, row 1 to 3 are headers, row 12 & 13 are empty, and row 14 & 15 are headers again, etc).
The iOffset is an integer declaration (set for cases to look at values in certain ranges)

Range("W4").Formula = "=AVERAGE(K4:OFFSET(H4,," & iOffset & "))"
Range("W5").Formula = "=AVERAGE(K5:OFFSET(H5,," & iOffset & "))"
Range("W6").Formula = "=AVERAGE(K6:OFFSET(H6,," & iOffset & "))"
Range("W7").Formula = "=AVERAGE(K7:OFFSET(H7,," & iOffset & "))"
Range("W8").Formula = "=AVERAGE(K8:OFFSET(H8,," & iOffset & "))"
Range("W9").Formula = "=AVERAGE(K9:OFFSET(H9,," & iOffset & "))"
Range("W10").Formula = "=AVERAGE(K10:OFFSET(H10,," & iOffset & "))"
Range("W11").Formula = "=AVERAGE(K11:OFFSET(H11,," & iOffset & "))"

Range("W22").Formula = "=AVERAGE(K22:OFFSET(H22,," & iOffset & "))"
Range("W23").Formula = "=AVERAGE(K23:OFFSET(H23,," & iOffset & "))"
Range("W24").Formula = "=SUM(W22:W23)"
Range("W25").Formula = "=AVERAGE(K25:OFFSET(H25,," & iOffset & "))"
Range("W26").Formula = "=AVERAGE(K26:OFFSET(H26,," & iOffset & "))"
Range("W27").Formula = "=SUM(W25:W26)"
Range("W28").Formula = "=AVERAGE(K28:OFFSET(H28,," & iOffset & "))"
Range("W29").Formula = "=AVERAGE(K29:OFFSET(H29,," & iOffset & "))"

Range("W36").Formula = "=AVERAGE(K36:OFFSET(H36,," & iOffset & "))"
Range("W37").Formula = "=AVERAGE(K37:OFFSET(H37,," & iOffset & "))"
Range("W38").Formula = "=AVERAGE(K38:OFFSET(H38,," & iOffset & "))"

Range("W51").Formula = "=SUM(K51:OFFSET(BH51,," & iOffset & "))"
Range("W52").Formula = "=SUM(K52:OFFSET(BH52,," & iOffset & "))"
Range("W53").Formula = "=SUM(K53:OFFSET(BH53,," & iOffset & "))"
Range("W54").Formula = "=SUM(K54:OFFSET(BH54,," & iOffset & "))"

Range("W61").Formula = "=SUM(K61:OFFSET(H61,," & iOffset & "))"
Range("W62").Formula = "=SUM(K62:OFFSET(H62,," & iOffset & "))"
Range("W63").Formula = "=SUM(K63:OFFSET(H63,," & iOffset & "))"
Range("W64").Formula = "=SUM(K64:OFFSET(H64,," & iOffset & "))"

Welcome to the Forum!

Here's one way you could cut down the code lines, and also get rid of the volatile OFFSET function calls.

Code: 
Range("W4:W11,W22:W29,W36:W38").Formula = "=AVERAGE(K4:" & Range("H4").Offset(, iOffset).Address(0, 0) & ")"
Range("W24,W27").Formula = "=SUM(W22:W23)"

Range("W51:W54").Formula = "=SUM(K51:" & Range("BH51").Offset(, iOffset).Address(0, 0) & ")"
Range("W61:W64").Formula = "=SUM(K51:" & Range("H61").Offset(, iOffset).Address(0, 0) & ")"

But why use VBA at all? With all these ranges hard-coded, you're going to have problems if you rearrange the rows and columns of your workbook in any way.

Instead, why not make iOffset an Excel name (i.e. rather than a VBA variable). Then you can just have Excel formulae, e.g.

W4: =AVERAGE(K4:OFFSET(H4,,iOffset)) which will adjust automatically if you start inserting/deleting rows/columns

Thank you for the response, StephenCrump.

As for your suggestion to make iOffset an Excel name instead of a VBA variable, I don't think I understand how to get that done, as I am not familiar with it.
How do I turn a variable of cases into an excel name so I can use it in a formula?

Below is what the case variables that was declared for the iOffset.
(the iOffset value is a manual input via messagebox, the value should be one of the cases listed below)

Code: 
Dim iOffset As Integer

Select Case iOffset
    Case 1
        Range("D52").Value = "EOP Nov"
        Range("E52").Value = "EOP Dec"
        Range("E54").Value = "EOP Dec"
        Range("F54").Value = "FCST Jan"
        Range("D59").Value = "EOP Nov"
        Range("E59").Value = "EOP Dec"
        Range("E61").Value = "EOP Dec"
        Range("F61").Value = "FCST Jan"
    Case 2
        Range("D52").Value = "EOP Dec"
        Range("E52").Value = "EOP Jan"
        Range("E54").Value = "EOP Jan"
        Range("F54").Value = "FCST Feb"
        Range("D59").Value = "EOP Dec"
        Range("E59").Value = "EOP Jan"
        Range("E61").Value = "EOP Jan"
        Range("F61").Value = "FCST Feb"
    Case 3
        Range("D52").Value = "EOP Jan"
        Range("E52").Value = "EOP Feb"
        Range("E54").Value = "EOP Feb"
        Range("F54").Value = "FCST Mar"
        Range("D59").Value = "EOP Jan"
        Range("E59").Value = "EOP Feb"
        Range("E61").Value = "EOP Feb"
        Range("F61").Value = "FCST Mar"
    Case 4
        Range("D52").Value = "EOP Feb"
        Range("E52").Value = "EOP Mar"
        Range("E54").Value = "EOP Mar"
        Range("F54").Value = "FCST Apr"
        Range("D59").Value = "EOP Feb"
        Range("E59").Value = "EOP Mar"

You could replace this second block of code with the more succinct:

Code: 
Dim sDate As Variant
Dim iOffset As Integer
iOffset = 1    'say

sDate = Array("Jan", "Feb", "Mar", "Apr", "May", "Jun", "Jul", "Aug", "Sep", "Oct", "Nov", "Dec")

Range("D52,D59").Value = "EOP " & sDate((iOffset + 9) Mod 12)
Range("E52,E54,E59,E61").Value = "EOP " & sDate((iOffset + 10) Mod 12)
Range("F54,F61").Value = "FCST " & sDate(iOffset - 1)

But again, why use VBA when you can do this using simple formulae?

If you have an Excel named range called iOffset (say), then your formulae could include, for example:

D52: ="EOP " & TEXT(DATE(2016,iOffset-2,1),"mmm")
F54: ="FCST " & TEXT(DATE(2016,iOffset,1),"mmm")
etc

If you want to, you could populate this range using VBA, e.g.

Code: 
Dim vInput As Variant
vInput = Application.InputBox("Enter 1 to 12", , , , , , , 1)

If vInput Then
    With Worksheets("Sheet1").Range("A1")
        .Value = vInput
        .Name = "iOffset"
    End With
Else
    'User has cancelled
    'Do something else
End If
