I have a two columns: Name and Amount. I want to apply a unique filter on the Name and retrieve the Sum of all the repeated Amounts.
How do I do this?

e.g.

A 5
A 4
A 1
B 20
B 40
C 0.3
C 0.4

should give me the result:

A 10
B 60
C 0.7

Please help. Thanks

Hi fnkhan111,

Have you considered an array formula?

Try this:
=SUM(IF(\$A\$1:\$A\$7="A",1,0)*(\$B\$1:\$B\$7))
Confirm this formula by hitting Ctrl+Shift+Enter.
Drag the formula down two rows and replace the bold A by a B and C and you are done.
Remember to confirm the formula by hitting Ctrl+Shift+Enter after editing the formula.

Best regards,
Trowa
Hi Trowa,
Thanks - however, I had provided a very simplified version of my data set.
I have thousands of lines of data and there are about 500 unique entries.
Is there a way to sum each of the unique entities automatically?
Thanks

This is also an array formula. You need to enter it as Trowa instructed earlier

=IF(ISERROR(MATCH(1,COUNTIF(\$A\$1:A1,\$A\$1:\$A\$7),0)), "", SUMIF(\$A\$1:\$A\$7, "=" & INDEX(\$A\$1:\$A\$7,MATCH(1,COUNTIF(\$A\$1:A1,\$A\$1:\$A\$7),0)),B:B ))

This is to entered row 1, else modify accordingly. Once entered, drag it down to last row
