Hello,

I have figured out how to calculate the total weighted average in my data sheet with this formula:

=SUMPRODUCT((DATA!AA285:AA20000)*(DATA!N285:N20000))/(SUM(DATA!N285:N20000))

Now I need to figure out, how I can calculate this with two criterias;
1) DATA!AH285:AH20000=Distrikter!C3
2) DATA!H285:H20000=Distrikter!D2

I am not sure what to do from here - maybe IF or another SUMPRODUCT.

Thank you for considering my request, I have used several hours on this now...

Try...
Rich (BB code): 
=SUMPRODUCT(
    --(DATA!AH285:AH20000=Distrikter!C3),
    --(DATA!H285:H20000=Distrikter!D2),
    DATA!AA285:AA20000,
    DATA!N285:N20000)/
  SUMPRODUCT(
    --(DATA!AH285:AH20000=Distrikter!C3),
    --(DATA!H285:H20000=Distrikter!D2),
    DATA!N285:N20000)

If you re on Excel 2007 or later:
Rich (BB code): 
=SUMPRODUCT(
    --(DATA!AH285:AH20000=Distrikter!C3),
    --(DATA!H285:H20000=Distrikter!D2),
    DATA!AA285:AA20000,
    DATA!N285:N20000)/
  SUMIFS(
    DATA!N285:N20000
    DATA!AH285:AH20000,Distrikter!C3,
    DATA!H285:H20000,Distrikter!D2)
Click to expand...

It still returns #N/A. By the way - how do easily type in the code as you have written? (I may be a newbie: I just corrected ',' into ';' and deleted new lines)

Excel Facts

Will the fill handle fill 1, 2, 3?
Yes! Type 1 in a cell. Hold down Ctrl while you drag the fill handle.
Thanks everyone, I have learned how to use iferror now..

I just registered at this community today, and I am very thankful for all your quick responses!

Wrap the formule between [x] and [/x] where x = code.

If you modify the formula in the range in AH such that it does not return #N/A...
Rich (BB code): 
=SUMPRODUCT(
    --(DATA!AH285:AH20000=Distrikter!C3),
    --(DATA!H285:H20000=Distrikter!D2),
    DATA!AA285:AA20000,
    DATA!N285:N20000)/
  SUMIFS(
    DATA!N285:N20000,
    DATA!AH285:AH20000,Distrikter!C3,
    DATA!H285:H20000,Distrikter!D2)


Otherwise:

Control+shift+enter, not just enter...
Rich (BB code): 
=SUM(
   IF(1-ISNA(DATA!AH285:AH20000),
   IF(DATA!AH285:AH20000=Distrikter!C3,
   IF(DATA!H285:H20000=Distrikter!D2,
    DATA!AA285:AA20000*DATA!N285:N20000))))/
 SUM(
   IF(1-ISNA(DATA!AH285:AH20000),
   IF(DATA!AH285:AH20000=Distrikter!C3,
   IF(DATA!H285:H20000,Distrikter!D2,
    DATA!N285:N20000))))

Thanks a lot, this is very helpful! :)

Hi everyone,

I'm trying to calculate something very similar and I can't seem to get the formula to work. Here's an example table:

[TABLE="width: 500"]
<tbody>[TR]
[TD]Group[/TD]
[TD]Score[/TD]
[TD]Percentage[/TD]
[/TR]
[TR]
[TD]1[/TD]
[TD]8769[/TD]
[TD]94%[/TD]
[/TR]
[TR]
[TD]1[/TD]
[TD]986757[/TD]
[TD]96%[/TD]
[/TR]
[TR]
[TD]1[/TD]
[TD]685[/TD]
[TD]100%[/TD]
[/TR]
[TR]
[TD]2[/TD]
[TD]765874[/TD]
[TD]87%[/TD]
[/TR]
[TR]
[TD]2[/TD]
[TD]7644[/TD]
[TD]90%[/TD]
[/TR]
[TR]
[TD]2[/TD]
[TD]76875[/TD]
[TD]90%[/TD]
[/TR]
[TR]
[TD]3[/TD]
[TD]7654[/TD]
[TD]2%[/TD]
[/TR]
[TR]
[TD]3[/TD]
[TD]76546[/TD]
[TD]40%[/TD]
[/TR]
[TR]
[TD]3[/TD]
[TD]76453[/TD]
[TD]89%[/TD]
[/TR]
[TR]
[TD]4[/TD]
[TD]8765[/TD]
[TD]65%[/TD]
[/TR]
[TR]
[TD]4[/TD]
[TD]876554[/TD]
[TD]98%
[/TD]
[/TR]
</tbody>[/TABLE]

I would like the weighed average of a group to return in one cell based on the group I select. Essentially, if group=1, return the weighted average of group 1, if group=2, return the weighted average of group 2 and so on.

I'm using a sumproduct formula but it's not dynamic, so when I filter by various groups I get the same weighted average:
=SUMPRODUCT($B$4:$B$219,$C$4:$C$219)/SUM($B$4:$B$219)

Could you all please help me adjust the formula so that it is dynamic based on a selected group? Thanks a million for your help.

In F2 enter and copy down:

=SUMPRODUCT(($A$2:$A$12=E2)+0,$B$2:$B$12,$C$2:$C$12)/SUMIFS($C$2:$C$12,$A$2:$A$12,E2)
