how to sum groups of 7 cells
 

If I have cells B4 to B250 filled with numbers and I want to sum every seven
cells (B4:B10, B11:B17, etc...). How can I do it such that in I4 is the sum
of the 1st seven, I5 the sum of the second 7, and so on.
I know I can do it manually but I have so many to do that I really need an
automated way of doing it.
Thank you in advance!

=SUM(OFFSET(B$4,(ROW(I4)-ROW(I$4))*7,0,7)) and copy down.

Enter this formula in I4 and copy down as needed:

=SUM(OFFSET(B$4,(ROWS(I$4:I4)-1)*7,,7))

What is the difference between the Offset Function and the Index Function?

Hi Dermot

In I4 enter
=SUM(INDEX(B:B,4+7*(ROW(A1)-1)):INDEX(B:B,10+7*(ROW(A1)-1)))
and copy down as far as required

Offset is volatile while Index is not
