Hi all,

I have an formula today that I use to calculate the FY week number. The problem is that with my table, 80k+ rows and expanding, this is a very slow process.

Does anyone have an suggestion on how to speed up this formula?

Code:
[COLOR=#333333]=WEEKNUM(A2,1)-26+IF(MONTH(A2)<7,52,0)[/COLOR]

Can you AutoAverage in Excel?
There is a drop-down next to the AutoSum symbol. Open the drop-down to choose AVERAGE, COUNT, MAX, or MIN
If you copy paste special > values the first 78K, then you formula only needs to work on the current 2K odd as the rest will be static

That was interesting.. I see how this should speed everything up, but it didn't. Even when I changed all 80k rows to be static the sheet(that consist of a big table) still takes a long time to calculate every time I make a change.

So the problem must be with the formulas that refers to the this table. I'll have to look into them instead.

Thanks for your help =)

so now look for volatile functions, things that recalculate every time you update like NOW() that supports other cells
