This formula works for me:
=SUMPRODUCT(1*(COUNTIF(A1:A100,A1:A100)>1),(B1:B100))
or for entire column (a little bit slower):
=SUMPRODUCT(1*(COUNTIF(A:A,A:A)>1),(B:B))
Pregunta
If there a way to use a sumif combined with a countif?
for example if I have
TransactionNo|NumberToSum
1 |
1 | 9
2 | 6
3 | 3
4 |
4 | 4
5 | 6
6 | 4
7 |
7 | 9
8 | 7
9 | 4
10 |
10 | 1
11 | 3
12 | 6
My result would be: 23
because the values 1,4,7,10
are duplicated, so I need to sum the NumberToSum
of those 9,4,9,1
in this case.
Ideally I would like somethings along the lines of =SumIf(A:A,Count>1,B:B)
Where B is summed if the count of A inside of A:A is > 1.
but =SUMIF(A:A,COUNT(A:A)>1,B:B)
does not work.
NOTE: the Data is NOT sorted as it appears in my example.
If I wanted to do it in VBA one quick way could be:
Sub sumdups()
Dim rng As Range
Dim rng2 As Range
Dim Sum As Long
Set rng = [A2:A17]
For Each rng2 In rng
If WorksheetFunction.CountIf(Range("A1:A17"), rng2.Value) > 1 Then
Sum = Sum + rng2.Offset(0, 1).Value
End If
Next rng2
End Sub
Another option I have tried is to add a column with the formula
=IF(COUNTIF(A:A,A2)>1,B2,"")
Then sum the helper column, but I am hoping there is a simple formula that can do the same all in one cell.
I am really just looking for a faster formula that can be entered in a single cell, without the need for any additional calculations.
