If to repeat your formula to make it more universal when

`=SUM(B\$4:\$B4)/COUNT(B\$4:\$B4)`

Or you mean something else?

Hi Baklan,
thanks for your quick reply. I got this but what the real problem is how to perfrom this action in Pivot table. I have a month coulumn form 1 to 12. Then in second column I have an average of some numbers repeating monthly. in the third I want to perform the above action.

# Re: Excel Cumulative Sum

please see the picture in attachment. I want to perform that incrementing cummulative action in pivot in the red marked area.

# Re: Excel Cumulative Sum

For cumulative sum, the formula is:
=SUM(B\$4:B4)
For cumulative average, as what it seems you need, the formula is:
=AVERAGE(B\$4:B4)

# Re: Excel Cumulative Sum

@Ubaid ur Rahman , so, like in your Excel file example but within PivotTable, correct?

# Re: Excel Cumulative Sum

@Sergei Baklan yes! as shown in the picture that how to simply apply that above formula to that column.

# Re: Excel Cumulative Sum

@Ubaid ur Rahman and how do you pivot first column, what gives 2.27 in Grand total?

# Re: Excel Cumulative Sum

@Sergei Baklan I don't need grand total. It comes up auto. So if possible without Grand total.

Solution

@Ubaid ur Rahman , I tried to do that on your data model, but didn't catch what do you calculate in it. Thus emulate on the table

It is named as Range in data model, the measure will be

```CumulativeCountDifd:=CALCULATE (
SUM ( [Actual value] )/COUNTROWS(Range),
FILTER ( ALLEXCEPT ( Range, Range[Year] ), Range[Month] <= MAX ( Range[Month] ) )
)```

You may it in Power Pivot and result is in second sheet.
