I am making a budget spreadsheet in which I keep each month's expenses
in one column and then the annual expenses in another column.

For example, the January (month 1) expenses for line item 1001 are
$100 and therefore the annual expenses for line item 1001 are $100.

In February the 1001 expenses are $200 and therefore the annual 1001
expenses are last month's 1001 expenses ($100) plus this month's 1001
expenses ($200) which is $300.

Without keeping a separate column for each month's line item expenses,
is there a tricky way of adding a number to itself? That is, when I
enter $200 into the February spreadsheet how can I add the annual
expenses to it without keeping a separate tally sheet somewhere else?

Jim

Option Explicit
Dim oldvalue As Double
Right click sheet tabview codeinsert this.
Now, when you enter a value in a5 it will be added to what is there
'====
Option Explicit
Dim oldvalue As Double
Private Sub Worksheet_Change(ByVal target As Excel.Range)
If target.Address = "$A$5" Then
On Error GoTo fixit
Application.EnableEvents = False
If target.Value = 0 Then oldvalue = 0
target.Value = 1 * target.Value + oldvalue
oldvalue = target.Value
fixit:
Application.EnableEvents = True
End If
End Sub

Can be done.....see Don's response.

But what you are asking for is fraught with peril.

No way to trouble shoot any errors in data input.

Once the new value is added to old, the old data is gone.

Say you had 100 in a cell, then you want to add 200.

Don's code will allow that but what if you inadvertantly added 209?

How will you keep track of current and past entries?

You have no 'paper trail" to follow to see how you got the results you have.

You'll be scratching your head wondering where and when the data input was
not done correctly.

Excel sheet has many cells.

Why not use them?

I came to that conclusion myself, the "paper" trail (actually a cell
trail) is a Good Thing® so I made a matrix sheet of account numbers
and months, then linked the main sheet to each cell in the matrix
sheet so that I have a running tally on the main sheet of that months
expenses plus a summed column of the year to date expenses.

To change months you do a simple Find&Replace replacing last month's
column letter with this month's column letter. Pretty simple once I
got my head wrapped around it.

Thanks for all your help...

I find myself doing that Don.

Let's say that the your Y-T-D is column D1 and your monthly column is called C1, then what you want to do is in column D1 enter the formula: =SUM(C1,D1). You are going to get an error message (called a circular reference)close it. Now go to the excel menu (it's the little circle on the left hand corner with the microsoft symbol) and click on excel options, then go to formulas.
There you will enable iterative calculation and enter 1 in the maximum iterations and in the maximum change also.

i hope this helps...
