I have 12 different worksheets for each month in a year in one workbook. In
each month's worksheet, I want year-to-date figures up to that month. All
the worksheets have the same fields in same cells. I prepare one worksheet
with all data and formulas for one month. Then I name the worksheet "Jan"
for January and copy that worksheet 11 times and rename them according to
individual months.

How can I insert a common formula that will work in every worksheet for
getting the year-to-date figures in each month's worksheet?

Thanks in advance for your time.

If you're willing to use a User Defined Function.......

Function PrevSheet(rg As Range)
n = Application.Caller.Parent.Index
If n = 1 Then
PrevSheet = CVErr(xlErrRef)
ElseIf TypeName(Sheets(n - 1)) = "Chart" Then
PrevSheet = CVErr(xlErrNA)
Else
PrevSheet = Sheets(n - 1).Range(rg.Address).Value
End If
End Function

Say you have 12 sheets, sheet1 through sheet12...........sheet names don't
matter.

In sheet1 you have a formula in A10 =SUM(A1:A9)

Select second sheet and SHIFT + Click last sheet

In active sheet A10 enter =SUM(PrevSheet(A10),A1:A9)

Ungroup the sheets.

Each A10 will have the sum of the previous sheet's A10 plus the sum of the
current sheet's A1:A9

Let's say that in each sheet the monthly value is in B9 and we want the cumm
to date in B10.

In Feb sheet in cell B10 enter:
=B9+Jan!B10

In the Mar sheet in B10 enter:
=B9+Feb!B10

etc.


B10 builds cummulatively month-by-month
