Speed up =sumif(A:A,A:A,B:B) ?

=sumif(A:A,A:A,B:B)

Very quickly gets very slow.

What ways are there to tell it not to add up one million rows (or whatever)?

Typically the business use involves a very few thousand rows, tops. Usually 1 or 2 thousand only.

Purpose is balances by (accounting) reference.

I plan to make it a named formula, so any array type solutions also welcome.

I am trying to avoid A1:A1000 as a solution.

You could try using dynamic named ranges that will only include rows with values.

What data do you have in the 3 columns?

By the way, the criteria (3rd argument) is normally a single expression not a range.

Get your data...
highlight a cell inside it...
then use Data > InsertTable

Then use FormulaNames to name the table.
Then in sumif start typing the table name... it will appear in the list... then open square brackets and a list of your columns will appear.
Construct formula this way =SUMIF(Table1[AA],"A*",Table1[BB])

See attached.

The table will grow / shrink as data in it changes, so the ranges will be the right size automaticaly.

Normally SUMIF only uses the "used range" anyway so actually using the whole column for the ranges isn't normally any more "expensive" than using a named range.....but why are you using a whole column for the criteria range? If the formula should be copied down then use just

=sumif(A:A,A1,B:B)

in row 1 copied down

Also do you need a sum on each row even if A1 is repeated? You could invoke SUMIF just on the first row for each repeated value, i.e. like

=IF(COUNTIF(A$1:A1,A1)=1,SUMIF(A:A,A1,B:B),"")

What data do you have in the 3 columns?

invoice numbers
reference number being cross reference to the payment
amount of invoice(s)
amount of payment

amount of payment contains a sumif to derive the payment from the invoices with the same reference as this payment

amount of balance remaining unpaid per invoice

ok, that's more than 3 columns.
if all Greek I will write and upload an example.

Anthony (I have seen the replies above and now savouring them, thank you).

edit: if an example is needed I will make it another question.

edit I am wondering if the answer is as simple as the twice mentioned criteria needs only be one cell not a column.

Points for (if as a mere aside) directly and being the first to solve the problem. The Range as criteria was slowing everything down.
