Add specified amount of numbers in a list

[judoist]

I have a long list of numbers in column A. I'd like to be able to add these numbers, 20 at a time... i.e. numbers 1 -20, 21 -40, 41- 60, etc.

Any ideas ?

Hi,

Try

=SUM(INDIRECT("a"&(ROW()-1)*20+1&":A"&ROW()*20))

and formula-drag that down for 1/20th of the number of rows involved

Another option

=SUM(OFFSET($A$1,(ROW(A1)-1)*20,0,20,1))
